Bacterial vaginosis (BV) is a common vaginal infection among women of reproductive age. Increasing evidence suggests BV may be sexually transmitted indicating a potential role for the treatment of sexual partners. If partner treatment reduces BV recurrence in women, real-world success will depend on sexual partners’ willingness to accept it. However, a lack of data exists on the acceptability of partner treatment among sexual partners, and no data exists on male partners’ experience of BV specifically. The aim of this study was to explore male partners’ views and experience of BV and their attitudes toward associated partner treatment. A social constructionist approach informed the framework of this study. Semi structured interviews were conducted with eleven men who participated in a BV partner treatment trial. Interviews were transcribed verbatim and analysed thematically. In the absence of symptoms in themselves, BV had little impact on men beyond their concerns for their partner’s health and self-esteem. Acceptance of treatment was largely a demonstration of care and support. While all participants had accepted treatment, men surmised the primary reasons other men may reject treatment as being: if they felt BV had “nothing to do with them”, which was related to not wanting to be viewed as having a ‘problem’ and exacerbated by norms of masculinity and STI-related stigma; lack of a diagnostic test to indicate if a male “had BV”; and a casual or less established relationship. Men’s attitudes to BV and partner treatment were primarily influenced by the nature of their relationships. The ambiguous aetiology of BV appears to attenuate STI related stigma and questions of infidelity.
Bacterial vaginosis (BV) is the most common vaginal infection in reproductive aged women globally [
While BV can result in adverse physical sequelae, several studies have also shown the symptoms of BV often have a significant impact on women’s psychosocial well-being and relationships [
Given its high global prevalence, associated morbidity, high rates of recurrence, and adverse psychosocial impacts, identifying new approaches to improve sustained cure for BV in women is of significant public health importance.
The concept that BV may be sexually transmitted, with incident and recurrent infections due to exposure to infected sexual partners, has been a controversial area of inquiry for the last 50 years. Currently, BV is not considered an STI and treatment of partners is not routine practice in any clinical guideline. While there is strong evidence supporting a dominant role for sexual transmission in the pathogenesis of BV, other factors may also contribute, although BV is rare/absent in women prior to sexual debut [
Determining whether BV is sexually transmitted has been complicated by difficulties in determining its aetiology, lack of clear evidence of infection in males, and the failure of five out of six partner treatment trials to demonstrate an impact on recurrence [
Currently, researchers at the largest free sexual health clinic in Victoria, Australia, the Melbourne Sexual Health Centre (MSHC), are conducting the StepUp Randomised Control Trial (StepUpTrial; Australian and New Zealand Clinical trial registry: ACTRN12619000196145). This is a well-powered MPT trial of treatment of women and concurrent treatment of their male partners with combined oral and topical antimicrobial therapy. The RCT aims to determine whether MPT improves BV cure and reduces associated sequelae in women. If successful, this will represent a major shift in the way BV is managed and, for the first time, provide an opportunity for the long-term control of this infection that has such significant health, economic and personal costs [
Though considerable qualitative literature regarding attitudes to partner
To date, there is a lack of data on men’s views and experiences of BV within their relationship, and their attitudes to the possibility of being offered partner treatment. The aim of this study was to explore male partners’ experiences of BV and the acceptability of associated MPT for BV. If MPT is found to be effective, a nuanced understanding of what motivates men to accept or decline treatment will be crucial to the successful uptake of MPT. This study adds to the extremely limited qualitative literature of partner treatment acceptance for genital infections more generally. This will be the first study to provide an insight into how BV infections affect men, developing a body of knowledge that provides a holistic view of BV’s impact on both partners in a sexual relationship.
This study has been reported in accordance to the Consolidated criteria for reporting qualitative research (COREQ) guidelines [
Ethical approval for this study was granted by the Alfred Hospital Ethics Committee, Victoria, Australia, Application Number 506/18 on the 27th November 2018.
A social constructionist methodology informed this study, as partner treatment is a function of a social relationship by its very nature. Social constructionism fits within the research paradigm of interpretivism which seeks to understand ‘the nuanced world of lived experience from the point of view of those who live it’ [
Despite not being classified as an STI, the genital location of BV means it is likely to be similarly understood. STIs are highly stigmatised conditions, and the negative social connotations of genital infections are likely to influence how people perceive, cope with and respond to a diagnosis and treatment of BV.
Theories of gender and health argue that health-related beliefs and behaviours are a means for demonstrating masculinity and are therefore culturally understood symbols that can be leveraged to assert a particular identity or cultural norm [
Semi-structured interviews were utilised to explore lived experiences from the first person point of view [
All interviews were conducted by RW, an experienced sexual health and research nurse at MSHC who undertook the research a part of her Masters of Public Health. As a sexual health nurse, RW is highly accustomed to speaking to people about sexual health and has a sound understanding of the epidemiology of BV. However, it is acknowledged that RW’s gender (cisgender woman) and profession may have influenced the nature of information participants shared. RW had no prior relationship with participants and is not part of the StepUp studies’ recruitment team. Men were informed that the research was being undertaken to better understand men’s perceptions and experiences of BV, as well as motivations for the acceptance or rejection of male partner treatment.
This study was conducted at Melbourne Sexual Health Centre, Victoria Australia.
Men were purposively recruited through the StepUp pilot and RCT (StepUp studies) as it allowed access to men who had been offered partner treatment for BV, something which is not yet standard clinical practice.
Within the Step Up studies, male partners of women being treated for BV were randomised to oral Metronidazole and a topical antibiotic cream applied to the penis twice a day for 7 days or current standard of care (female treatment only). Participants self-collected genital samples monthly for a follow up period of 3 months. All male procedures, including initial recruitment were able to be conducted remotely via phone and using post packs. To ensure consistency, all male partners were provided with the same information regarding the trial and BV at recruitment; that BV is a commonly occurring infection in women, that BV associated bacteria have been found on male genitals and that these bacteria may be exchanged during sex. No further education was provided. Men were also made aware that all answers in questionnaires were kept strictly confidential and not shared with partners.
As men must have been offered the opportunity to participate in the StepUp studies to be eligible for interview, with the eligibility criteria for this outlined in
• Female partner with a confirmed clinical diagnosis of BV who has been offered participation in either the Step Up Pilot or Step Up RCT |
• Aged 18 years or above |
• Monogamous relationship with female partner for minimum of 8 weeks |
• Sufficient English proficiency to understand study requirements |
• Able to comply with study requirements |
• No contraindications to treatment |
• Had been offered participation in Step Up studies |
• Consented to audio recording of interview |
As described, this study aimed to recruit men who had either accepted or declined MPT through the StepUp studies. Men were recruited in one of three ways.
All men who were still actively engaged in the StepUp pilot at the time of ethics approval were contacted via a single SMS offering the opportunity to participate in the qualitative study. Men were invited to contact the study number if they were interested in participating. If they did not respond to the SMS, no further contact was made.
Men who participated in the RCT could indicate their interest in being interviewed by checking a tickbox on the StepUp RCT consent form. If men checked this box, their contact details were forwarded to RW. All men who provided consent were contacted by RW until saturation was deemed to be met.
Men who declined participation in the StepUp studies were contacted through their female partners who were provided with a flyer including a summary of this study and the research telephone number. Men were invited to contact the study telephone number if they were interested in participating.
RW contacted all men who had indicated their interest to explain the study in detail and arrange an appropriate time for interview. Men were contacted a maximum of three times before being considered lost to follow up.
Men were offered the option of a face-to-face interview at MSHC or a telephone interview. Participants were provided with a Participant Information and Consent Form (PICF) prior to the interview which assured them participation was voluntary and that any data they provided would be treated confidentially. Men were informed their data would be stored on double password protected on-site databases, and no identifying information would be used in any publications arising from the study.
Men were informed that the interviews needed to be audio recorded to allow the interviewer to pay full attention to their accounts and lived experience of being offered BV treatment. No men raised concerns about the audio recording or declined to participate in the interview based on this requirement. Men were informed they did not need to answer any questions they were not comfortable with and could cease the interview at any point.
All participants chose to participate in a phone interview. Verbal consent was provided whereby RW read the previously provided consent form aloud and asked them to state their name, the date and affirmation of their consent. This was recorded on a separate audio file to their interview data to ensure confidentiality. No names were used during the interview.
All interviews were conducted between January and September 2019. Prior to interview, men were sent a copy of the PICF to ensure they had a full understanding of the study.
At the commencement of the interview, men were asked a number of demographic questions including length of their current relationship, prior STI testing and couple contraceptive use. Men were then asked a series of open-ended questions exploring men’s knowledge of BV, views and attitudes about STIs, the impact of BV on their relationship, motives for MPT acceptance and hypotheses why men may decline MPT. All interviews were audio recorded. Men were not reimbursed individually, but went into a ballot to receive a $200 gift card for their participation.
RW met regularly with JB and CV, experienced social researchers adept in qualitative methods in the area of sexual and reproductive health, to discuss the interviews and emerging themes. New lines of questioning were added throughout the data collection period including questions around the influence of uncertainty of infection in men on their willingness to accept MPT, and experience of personal symptoms (refer to

All interviews were transcribed and de-identified to protect confidentiality. An inductive latent thematic analysis [
During the recruitment period, before it was decided data saturation had been met, 20 men were eligible for this study. All eligible men were contacted for interview. Of those contacted, 11 men were interviewed; 7 were recruited from the StepUpPilot and 4 from the StepUpRCT. Of the remaining 9 men that were contacted, 8 did not respond to the SMS invitation and 1 decided to withdraw after consenting. These 9 men were not followed up further as per the study protocol and ethics approval. If data saturation had not been met after 11 interviews, further participants would have been prospectively recruited from the men enrolled in the ongoing StepUp RCT. All participants had received treatment, although two were yet to take the antibiotics at the time of the interview. No men who had declined participation in the StepUp studies contacted the research team to participate. As men could only be invited through their female partners who were not obliged to provide them with study information, it is not possible to know how many men who declined partner treatment were offered the opportunity to participate.
All participants chose the option of a telephone interview, which lasted between 20 to 60 minutes (average 39 minutes). Participants ranged in age from 23 to 60. All participants were in committed relationships and had been with their current partner from 4 months to 8 years, with half (n = 5) in relationships under a year in length. All had previous STI testing experience. Further participant characteristics are outlined in

Participant 10 was a man in his thirties who had himself experienced a “fishy” genital odour for over ten years. Symptoms would increase with any sexual activity and his sexual partners had also experienced many repeat BV infections, including his previous wife and current partner. This led him to believe his symptoms could be sexually transmitted, but this idea was previously rebuffed by his female partner due to BV being a “women’s issue”. The odour he experienced had a substantial effect on his sexual confidence, undermining his willingness to embark on new sexual relationships or receive oral sex due to fear of “the smell” being discovered. Despite the impact of his symptoms on his personal life, he came to understand “the smell” as “normal” and “just the way he was”. It was his care for his partner and witnessing her distress with BV that led him to investigate if there was any new research on sexual transmission of BV from men, as this continued to be his assumption. Had his partner not demonstrated concern about her own symptoms, he would not have sought further medical attention for himself. For this participant, who experienced a complete clearance of his symptoms following MPT, this prospect of ‘cure’ for his own symptoms was revolutionary. |
Participant 3 was a man in his twenties who had been in a relationship with his partner for over five years. His partner had asked him to participate in a similar MPT trial for BV at the beginning of their relationship, but he had declined at that time. His reasons for previously declining were: 1) He did not believe that BV had anything to do with him as he had no symptoms and had a clear previous STI screen—“it didn’t apply to me” 2) The relationship was relatively new—“we’re not that far into our relationship, so why do I need to do this for you?” 3) He simply did not want to–“I didn’t wanna do it, so I didn’t do it”. These reasons reflect the hypotheses of all participants around why men may not accept treatment. On this current occasion of being offered MPT, the more established nature of his relationship, and possibly the recurrence of his partner’s symptoms, were sufficient to lead to treatment acceptance despite no more evidence that his partner’s BV “had anything to do with him”. This demonstrates the central importance of the nature of a relationship (and how committed it is) in influencing MPT acceptance. Despite accepting treatment, this participant demonstrated an extremely judgmental attitude towards STIs and those who had experienced them, as well as demonstrating high levels of the type of “manly” masculinity described by all participants as a likely barrier to MPT acceptance. For this participant, the concept of BV as a “lady problem” was protective against the “crushing” social anxiety that he felt treatment for an STI would result in. |
Participant 1 was a man in his twenties who had been in his relationship for six months. He had noticed symptoms in his partner of slight odour and her discomfort during sex. The communication in the relationship was very open, leading to the couple seeking medical attention together to identify the cause of his partner’s symptoms. He was very receptive to the possibility that he could be a “carrier” and keen to have treatment to help and support his partner as he could “see the discomfort she was in”. He saw this as his role as a partner and believed that the support he had demonstrated for his partner through the process had strengthened their relationship. His partner had also compared the higher degree of comfort she experienced “going through this with him” than she would have with previous partners who would have been less supportive. This demonstrates the importance of female comfort in engaging men in MPT, as well as the role of the relationship and care. |
Table 4. Case scenarios demonstrating different impacts and experiences of BV and partner treatment.
Overall, men had little awareness of BV but had developed an understanding of the infection due to their participation in the StepUp studies.
Generally, men had low levels of awareness and knowledge about BV, unless they had previously been with a partner who had experienced the infection. Most men reported that prior to their partner’s diagnosis, they had never heard of BV. Men whose partners had previous experience of BV were more likely to show some knowledge of BV and less inclined to feel confused or frustrated as they knew it was a treatable condition.
Men in this study were informed as part of the BV studies that BV was not currently classed as an STI, however, increasing evidence suggests it is associated with sexual activity and that bacteria may be “exchanged between partners”.
Participants’ views around STIs varied. Some men viewed them as a part of life that one has to be proactive about identifying and addressing, whilst others saw an STI diagnosis as a personal failing that would “crush” them and endanger their standing in social networks.
Interestingly, as BV is not currently classified as an STI, men who demonstrated high levels of STI stigma did not express the same degree of distress, stigma, or fears of infidelity around BV that an STI diagnosis would evoke.
A number of men mentioned that “other men” may suspect their partner had been unfaithful due to the sudden appearance of symptoms, yet they did not. However one participant reported that if BV were classified as an STI, his partner’s diagnosis would have made him question her fidelity. This demonstrates that the impact of BV on men within their relationships centres to a great degree on how they understand the infection.
Whilst men generally spoke of not wanting their social networks to be aware of being treated for BV as this may be “embarrassing” and leave them open to ridicule, this was somewhat minimised by the current classification of BV. This suggests that the current conceptualisation of BV may be protective, despite a number of men identifying that STI stigma could be applied regardless of the classification of BV purely because of its genital location. Indeed, one participant identified that the “flexibility of the knowledge” could protect individuals from the stigma of STIs.
Overall, most men reported that BV did not directly impact on them physically or emotionally, beyond concern for their partner’s health and psychological wellbeing and the impact it had on their sexual relationship due to their partner’s concerns around symptoms.
Most men in this study felt BV had no direct impact on them physically as they did not experience any symptoms.
Interestingly, however, two men spoke of experiencing genital symptoms that they attributed to BV. One participant spoke of developing symptoms of genital discomfort and sensitivity after occasions of unprotected sex with his partner who had long standing symptoms of BV that she had been unable to have accurately diagnosed and managed.
Another spoke of having experienced a genital “fishy like” odour for
Men who felt they had experienced symptoms, were more likely to report personal impacts centring around blame, reduced self-esteem, and negative impacts on their sexual relationships and sex lives.
For the participant who had experienced a “fishy” odour for ten years, the impact of this symptom had a profound
The other participant’s symptoms did not undermine his own self-esteem but instead affected his attitude towards his partner and the relationship due to the belief that his partner had “given him something”. This generated unwanted and uncomfortable feelings of
Half of the men interviewed had not noticed any symptoms in their partner, while others most commonly noticed the malodour with descriptions ranging from “not a big deal” to “unpleasant”. Most men reported that their partners seemed more aware of the odour than they were and their partner’s embarrassment tended to have a negative impact on their sex lives and at times, caused tension and frustrations within the relationship.
Men did not generally see BV as a “big deal” in and of itself, but the impact of it on women’s self-esteem and confidence was of great concern. Many men identified that the impact of symptoms on their partners was significant, and led women to feel unattractive and sexually inadequate. This in turn affected women’s self-esteem, and men often felt a sense of helplessness around wanting to help their partners feel better, but not knowing how. Indeed, it was clear that the impact of BV on men centred largely around their partner’s response to their symptoms rather than the presence of symptoms themselves.
While men described various negative impacts of BV, many identified that the appearance of symptoms led them as a couple to improve their communication about sex and sexual health. The greatest positive impact however, was unquestionably the “bonding experience” of partner treatment which almost all men believed further strengthened their relationship.
All participants had accepted MPT and the main reasons they had accepted treatment centred on feeling it was part of being in a committed relationship, their role as a supportive partner and man, part of open communication in a relationship and concern around potentially being the source of infection.
The most important reason men accepted MPT was unquestionably to show care and support for their partner. Men largely viewed treatment as an avenue to support their partner and as a way to demonstrate their commitment to the relationship. Whilst some men related the desire to “help” their partner with the distress her symptoms seemed to cause her, the act of taking treatment was a symbolic affirmation of their role as a supportive partner, with or without referring to this distress. Indeed, one participant described the acceptance of MPT as a metaphor for the relationship, where trivialising of BV would be a trivialisation of his relationship.
For a number of men, having the option of partner treatment was reassuring as it gave them something tangible they could do to address the issue of BV.
Two participants were so motivated to help their partners who were frustrated with repeat BV infections, they proactively sought out further information and ways to help, such as the StepUp studies.
A number of men used the same language to say they felt it was their responsibility or role in the partnership as a man to support their partner. In this way, their sense of responsibility was linked to the nature of the relationship, but also male identity.
For a couple of men, this sense of male responsibility was more general and derived from a sense that women suffered disproportionately with reproductive health.
Interestingly, participants in this study often differentiated themselves from “other men”, who they felt could be unwilling to support their partners, take responsibility for sexual health issues or aligned themselves with traditional homophobic ideals of masculinity.
Open, trusting communication within the relationship was cited as an important element of treatment acceptance. However, a number of men noted that open communication could be hampered by women’s fear of being judged for having BV.
Though some participants felt their comfort in communicating openly was dependant on the length of the relationship, others stated that this had been a key element of their relationship from the beginning. Open communication enabled discussion of sexual health matters, allowed men to understand the cause of their partner’s distress, and often led to shared or supported decision-making about seeking medical help for BV.
Most men who understood BV as something they could potentially be “giving” to their partners were very pragmatic in their acceptance of MPT as a way to “fix it”.
For some men, the belief that they could unknowingly be posing a risk to their partners meant that they viewed treatment as a moral obligation. Men who were concerned about being a source of infection generally expressed that they would likely accept MPT regardless of the nature of the relationship within which it was offered, as this was the “right thing” to do.
All bar one participant described the treatment as easy, and a reason why they would accept MPT again in the future.
Despite having accepted MPT as part of the StepUp studies, many participants expressed strong views on why “other” men may decline MPT and hypothesised on what may influence their own choice of whether to accept MPT if they were offered it again in the future. Of note, one participant had previously been asked by his ongoing female partner to participate in a preliminary study by our group years prior, and had declined at that time (see
The primary reason participants believed men would refuse MPT, was due to a belief that BV had “nothing to do with them”. This was seen to be the product of a traditional masculine identity in which having a health “problem” may be perceived as “weak”; BV being understood as a “lady problem”; and the absence of physical symptoms or a confirmatory test for men.
Avoidance of treatment was cited by most participants as a way to prevent the spoiling of a “masculine” identity. They hypothesised that MPT acceptance could be viewed as an admission of “having something wrong with you”. Thus, MPT rejection could be a way for men to avoid this perception and responsibility. Participants linked this to traditional norms of masculinity, where “having something” is seen as “weak” and a personal failure. In this way, men would be able to conserve their masculine identity and “pride” by distancing themselves from the infection.
Of interest, one participant identified that if BV is indeed something that can involve men, the name itself may be alienating and somewhat feminising, presenting another potential barrier for “masculine” men.
Many men observed that the perception of BV as a purely female condition would lead to men declining treatment simply because they did not feel that taking it would present any personal benefit. This is particularly true in the absence of any symptoms in themselves.
The absence of symptoms in men and lack of a confirmatory test for males were generally viewed as important barriers to MPT acceptance. Despite having accepted treatment as part of a trial in an effort to address their partner’s distress, some participants also felt that they would want more evidence of infection in themselves if they were to accept treatment in the future, particularly if they were in a casual relationship.
Participants viewed casual or less established relationships as an important reason that men may decline MPT. Whilst accepting treatment within a committed relationship is a demonstration of care, acceptance of MPT for BV in a causal relationship may be seen as a favour. This was reflected by one participant when explaining why he had declined a preliminary MPT study by our group years prior.
The lack of “proof” of infection in themselves was viewed by all participants to be of greatest relevance in casual relationships.
Men were instructed not to drink alcohol or have sex during the seven days of antibiotic treatment. Participants generally felt that the treatment and its related restrictions would not be a huge barrier to treatment acceptance, however as noted earlier, other people knowing they were being treated for BV could be.
Participants believed that a fear of judgement from others would be an important reason men would decline MPT. Whilst being seen to “have a problem” could be perceived as “weak” in itself, the genital location of BV could evoke the stigma that surrounds STIs, leading to greater perceived judgement, ridicule, and shame. Thus, avoidance of MPT was a way to protect an inviolable, socially accepted identity.
Research exploring the impact of genital infections on intimate relationships is extremely limited and has focused exclusively on the accounts provided by those with a diagnosed infection [
This study has demonstrated that while the symptoms of BV often do have an impact on men’s sex lives this appears to be mainly due to the shame and embarrassment women feel, and men in this study demonstrated they are more concerned with the impact of symptoms on their partner’s self-esteem than their sex lives per se.
It has also shown that many men are often unaware of their partner’s symptoms and do not generally believe they are as noticeable as women believe they are. Women in other studies have reported receiving similar reassurances from their partners [
Men often noticed the distancing of their partners when symptoms were present, which reflects the finding by Bilardi
Different health conditions can be imbued with varied meanings in cultural and social contexts, affecting the way in which they are viewed and experienced [
However, several participants themselves demonstrated that the impact of STI stigma can be somewhat attenuated by the current ambiguity of the classification of BV. Men who discussed how they perceived of people who may have STIs and how they may feel with an STI diagnosis did not demonstrate the same response to partner treatment for BV. Furthermore, whilst men did not question the fidelity of their partners’ due to their BV diagnosis, this was in part due to an understanding that this condition was
What is clear from the results of this study is the central importance of the relationship in influencing not only the impact of BV on men, but their acceptance of treatment. Concern for partners was a unique driving force for treatment acceptance, not merely because men wanted to help ease their partner’s suffering, but because they viewed this as their role as a man in a partnership. Most previous BV MPT trials did not collect any information on the nature of the relationships of the participating couples, except for one in which 75% of couples were married [
Participants largely related MPT acceptance to ideas of being a good and supportive partner or a responsible, caring man; whilst they hypothesised that declining treatment may largely be a way for “other” men to maintain a “strong” “masculine” image. In this way, MPT can be understood as tool to demonstrate a certain type of masculine identity.
Participants unanimously identified that it was traditional norms of masculinity among “other” men that would likely represent the
However, numerous participants conceived that “being a man” meant being a supportive partner and “taking responsibility”. Many simultaneously did this whilst identifying themselves as “different to other men” which demonstrates the ironic observation of Wetherell and Edley (1999) that
A tendency in men’s studies is to analyse masculinities by looking only at men and relations among them, presuming that women and their relationships with men are irrelevant [
The central importance of the relationship is also reflected in the STI literature relating to partner notification. While we were unable to identify any studies that explore partner treatment acceptance, the literature demonstrates that men are more likely to notify partners of an STI diagnosis if they are in committed relationships, with stronger emotional ties [
Many participants identified that men, including themselves, may refuse MPT for BV due to the belief that treatment would be of no personal benefit. Similarly, a review of literature exploring HPV vaccination acceptability and intention to vaccinate among men demonstrated that this same belief that the vaccine would not directly benefit males was repeatedly cited as the primary reason men would decline HPV vaccination [
However, an unexpected finding of great interest in this study was the prolonged symptoms one participant experienced which he attributed to BV and his resulting belief that BV was sexually transmitted. This participant’s feelings of embarrassment, sexual withdrawal and self-stigmatization, and his reported hygiene practices to conceal his symptoms perfectly mirror the documented experiences of women with BV [
The major strength of this study is that it is the first study we are aware of to explore male partners’ views and experiences of BV and associated MPT, and has identified productive directions for future research.
This study has some very important limitations. Men who had not participated in the StepUp studies may have very different views from the men interviewed in this study. Despite attempting to recruit men who declined MPT through the StepUp studies, none of these men expressed interest in participating. Accordingly, all study participants had accepted MPT. Thus, the reasons identified for MPT decline are largely hypothetical, with the exception of one participant who had previously declined a similar study. As MPT is still experimental and access to it is part of a larger study with its’ own requirements, it cannot be said how this may have influenced MPT decline. The lack of cultural diversity among the men interviewed means this study may not have captured the diversity of attitudes or experiences among different populations of men. Male experience of symptoms was an unexpected theme that did not reach saturation and will be the subject of another study.
Considering the significant health and personal costs of BV on women, and economic costs of repeated infection, evidence of successful sustained cure in women through partner treatment would be a welcome management approach that could radically change the way the infection is managed. However, uptake of treatment by male partners may be heavily influenced by contextual factors that may improve or diminish their willingness to accept treatment. The subjective social norms that underpin how sexual health issues are viewed and how individuals “do gender” will no doubt exert a significant influence over men’s decision-making. Encouragingly, it seems that strong caring relationships may mitigate some of these issues, as does the fact BV is not currently classified an STI.
In the absence of male symptoms and a confirmatory test to “prove” the presence of infection in men, achieving MPT acceptance may be more challenging. Interestingly, this research suggests there may indeed be men suffering from BV like symptoms which may alter their understandings of the personal health benefit of seeking and accepting treatment.

5. Review Comments to the Author
Please use the space provided to explain your answers to the questions above. You may also include additional comments for the author, including concerns about dual publication, research ethics, or publication ethics. (Please upload your review as an attachment if it exceeds 20,000 characters)
Reviewer #1: The author fills an important knowledge gap of male perspectives on their partner’s BV infection, how that affects their relationship with their partner and what attitudes they have about getting treatment for BV, a condition that has typically has no effect on them physically but may give better recovery results for their partners.
Major:
- Ethics section needs more details particularly around confidentiality
- Doubts about maximum variation in participants and data saturation
- Interesting results but need to be presented in a better way
Minor:
- Check for grammar and typos (for example, lines 119, 133, 530…)
Introduction:
The argument is built well and the objective stated clearly.
Minor:
- You mention that BV being sexually transmitted is a controversial and debated idea and then you elaborate more on the possibility of it being sexually transmitted. I would like to see a short sentence summarising what the other lines of thought are if BV is not sexually transmitted, eg ethnic/racial pre-dispositions to BV, BV in women prior to sexual debut ++
Methods:
I liked how reflexivity regarding the interviewer’s gender and profession was considered during the interview process.
Major
- Ethics statements needs more elaboration on confidentiality and verbal consent. How was confidentiality ensured? Was verbal consent taken when setting up an interview time or just before the interview began?
- In Table 1, one of the eligibility criteria listed was “consented to audio recording of interview” Justify this criteria. Why was this important? If it is a sensitive/private topic then perhaps this introduced a bias in the group that agreed to speak with you as perhaps not everyone wants to be audio recorded even though they may not mind participating in the study. If you agree about potentially biased selection of respondents, include in limitations. If you disagree, explain a bit why this was a good approach for the current setting.
- Study setting is missing from methods. All I know is that a hospital in Victoria gave the ethical approval, but where was the study conducted? Later I read about phone interviews, but it needs to be clear in the methods where they were conducted.
- What was the age distribution of the respondents? And ethnicities? How did you ensure maximum variation in the respondents when you purposely selected them? Were your respondents varied enough to conclude saturation?
Minor
- It is unclear to me what you mean by “explore consciousness” on line 113
- Line 177, the acronym JB appears for the first time… who is this person? Why was this person an appropriate person to conclude data saturation? Explain
- You conducted phone interviews about a potentially private/sensitive topic – was anything done to build trust?
- Line 175: Influence on what?
-
Results
You have some interesting and useful findings to fill a knowledge gap.
Major:
- Table 4 is difficult to read, also this isn’t a case study from what I can tell, so presenting the variation as text and explaining it will be better.
- Analysis needs some more work and cleaning up for example, line 231/232: how are 3.1 and 3.2 different? 3.2 seems more about manhood/perceptions of masculinity than “the supportive man” while 4.1.1 also speaks of “manhood” a bit differently.
- Page 16/17: Case 2: “This participant demonstrated extremely high levels of STI stigma and traditional masculinity”. Here ‘stigma’ and ‘traditional masculinity’ need to be contextualised and defined. You do it a bit in your discussion but these concepts can be defined in the methods and theory section.
- Line 650-653: From the data presented here, it seems to me that their sex lives DO matter to them
-
Minor:
- Table 2 “How would they like to receive information” – what information? Specify.
- Line 194, You write about JB and CV being experienced social researchers. This should come earlier when or before JB was first introduced
- Line 200, How were the 20 men chosen to be contacted? Were there only 20 who contacted you with interest in being in a study? When you stopped at 11, did you contact the remaining 9 to inform them why they were not contacted further?
- Table 3. Did you mean “Average length of relationship”?
- The list of themes and sub themes is unnecessary
- Check for repetition in the results
-
Discussion
Major:
- Check for repetition
Minor:
Reviewer #2: This is a really well written article about men's experiences of BV and their views on male partner treatment. It is a qualitative study conducted alongside a RCT where women with confirmed BV were enrolled, as well as male partners.
A few comments:
It would be interesting to know a bit more about what the Step Up Trial consisted of for the male partners, beyond the eligibility requirements. Was it treatment only or were there other aspects of the study (e.g. education).
Consent process: Did the study team require written/electronic informed consent or verbal consent? A bit more detail on the consent process in the text would be helpful.
Recruitment: In the analysis, the authors state that they reached data saturation after 11 participants had been interviewed but, in the results section, it seems that the others who were not interviewed (the remaining 9 of the 20 contacted) were not interested in participating. Had data saturation not been reached, what would have happened?
Methods: 20-60 minute interviews seem quite short for lived experience research, what was the average length?
Results: What was the sexual identification of the 1 participant who did not identify as heterosexual?
Is there a better way to format the case scenarios? It was difficult to read side by side over several pages.
Discussion: Regarding your point about local categories of illnesses and its impact on the disease and treatment experiences (and acceptance), I wonder if there is any literature about the perceptions of men regarding vaccination for HPV and about stigma related to HPV care seeking. This literature, if it exists, might be interesting to explore.
I also think that the finding about BV not being classified as a STI is important to think about when working out how to communicate with the public about treatment and decision making as well as the case of the man who had symptoms.
Additionally, I do think that further research is needed into reasons men decline MPT beyond the hypothetical reasons listed by those who had already accepted it. The group interviewed were a very specific population as they were enrolled in studies about the topic with partners who were also enrolled in studies. Their views might be wildly different than those who refused participation and within the community more broadly but the finding from this study could be used to inform data collection in other studies.

Reviewer One
1. Introduction
1a) Comment
You mention that BV being sexually transmitted is a controversial and debated idea and then you elaborate more on the possibility of it being sexually transmitted. I would like to see a short sentence summarising what the other lines of thought are if BV is not sexually transmitted, e.g. ethnic/racial pre-dispositions to BV, BV in women prior to sexual debut ++
1a) Response
Thank you for your comment. The following line has been inserted into the introduction (lines 37 to 42) to address this point.
“While there is strong evidence supporting a dominant role for sexual transmission in the pathogenesis of BV, other factors may also contribute, although BV is rare/absent in women prior to sexual debut(1). These factors include racial variants in vaginal microbiota, altered host immunity, an endogenous source, environmental factors such as nutrition and intravaginal practices such as douching (2).”
2. Methods
2a) Comment
Ethics statements needs more elaboration on confidentiality and verbal consent. How was confidentiality ensured? Was verbal consent taken when setting up an interview time or just before the interview began?
2a) Response
Thank you for this comment. We have now elaborated on confidentiality and verbal consent in the Methods, under the recruitment and data collection sections. The following lines have been inserted or revised (in blue).
“RW contacted all men who had indicated their interest, to explain the study in detail and arrange an appropriate time for interview.” (Line 188)
“Participants were provided with a Participant Information and Consent Form (PICF) prior to the interview which assured them participation was voluntary and that any data they provided would be treated confidentially. Men were informed their data would be stored on double password protected on-site databases, and no identifying information would be used in any publications arising from the study.”
(Line 194-198)
“All participants chose to participate in a phone interview. Verbal consent was provided whereby RW read the previously provided consent form aloud and asked them to state their name, the date and affirmation of their consent. This was recorded on a separate audio file to their interview data to ensure confidentiality. No names were used during the interview.” (Line 207-211)
2b) Comment
In Table 1, one of the eligibility criteria listed was “consented to audio recording of interview” Justify this criteria. Why was this important? If it is a sensitive/private topic then perhaps this introduced a bias in the group that agreed to speak with you as perhaps not everyone wants to be audio recorded even though they may not mind participating in the study. If you agree about potentially biased selection of respondents, include in limitations. If you disagree, explain a bit why this was a good approach for the current setting.
2b) Response
The reviewer raises a valid point that the requirement for audio recording could potentially bias the group, however, this is our usual process in studies conducted through Melbourne Sexual Health Centre, particularly where sensitive topics exploring lived experiences are concerned. It is important that in interviews such as these, the interviewer is able to pay full attention to participants accounts and pursue relevant lines of questioning without distraction and enable an easy and comfortable flow of conversation. Men were informed when first contacted of the need to audio record the interview for these purposes, and no participants declined upon learning of this requirement. We have provided further justification for this eligibility requirement under “Data collection” with the following lines inserted:
“Men were informed that the interviews needed to be audio recorded to allow the interviewer to pay full attention to their accounts and lived experience of being offered BV treatment. No men raised concerns about the audio recording or declined to participate in the interview based on this requirement. Men were informed they did not need to answer any questions they were not comfortable with and could cease the interview at any point.” (Line 200-205)
2c) Comment
Study setting is missing from methods. All I know is that a hospital in Victoria gave the ethical approval, but where was the study conducted? Later I read about phone interviews, but it needs to be clear in the methods where they were conducted.
2c) Response
All participants were recruited through the Step Up trials which were conducted in and coordinated by the largest free sexual health clinic in Victoria, Australia, the Melbourne Sexual Health Centre (MSHC) (line 193-194). Participants were able to be interviewed in person at MSHC, or via phone (line 202). All participants elected to be interviewed over the phone (line 272). The aforementioned lines were in the submitted manuscript, and we have also added the following line (130) to clarify study location:
“This study was conducted at Melbourne Sexual Health Centre, Victoria Australia.” (Line 145)
2d) Comment
What was the age distribution of the respondents? And ethnicities? How did you ensure maximum variation in the respondents when you purposely selected them?
2d) Response
Only men with a lived experience of accepting or declining MPT within the StepUp study were eligible to participate as this was central to the research question. As maximum variation sampling is utilised to capture the available diversity of experiences relevant to the research question [1], contacting all eligible men provides the maximum variation possible within this very limited pool of eligible men. Men had to be eligible for participation in the StepUp studies and provide consent to be contacted about a qualitative research study. All men who were eligible to participate were contacted for interview, thereby providing insights from all available angles.
As noted in the paper, participants ranged in age from 23 to 60 (line 273), with a median age of 28 (Table 3). This was not an ethnically diverse sample, as only one participant was born outside of Australia (Table 3) and most identified as Australian with European ancestry. The limited cultural diversity of the sample has been highlighted in the limitations in the previously submitted manuscript.
“The lack of cultural diversity among the men interviewed means this study may not have captured the diversity of attitudes or experiences among different populations of men.” (Line 877-879)
In order to further clarify the limited size of the potential pool from which men could be recruited, and that all eligible men were contacted, the “Recruitment” section of the paper has been changed to “Recruitment and participant selection” (Line 144), the explanation of who was contacted and recruited has been altered as below.
“During the recruitment period, before it was decided data saturation had been met, 20 men were eligible for this study. All eligible men were contacted for interview. Of those contacted, 11 men were interviewed; 7 were recruited from the StepUpPilot and 4 from the StepUpRCT. Of the remaining 9 men that were contacted, 8 did not respond to the SMS invitation and 1 decided to withdraw after consenting. These 9 men were not followed up further as per the study protocol and ethics approval. If data saturation had not been met after 11 interviews, further participants would have been prospectively recruited from the men enrolled in the ongoing StepUp RCT.” (Line 255-263)
The following lines have also been amended (in blue) and added to the manuscript to improve clarity and address the questions about participants:
“All men who were still actively engaged in the StepUp pilot at the time of ethics approval were contacted via a single SMS offering the opportunity to participate in the qualitative study.” (Line 171-172)
“All men who provided consent were contacted by RW until saturation was deemed to be met.” (Line 179-180)
2e) Comment
Were your respondents varied enough to conclude saturation?
2e) Response
In addition to our response to Comment 2d above, saturation was reached within the available sample we were able to recruit. As noted in our earlier response, maximum diversity was limited but achieved among the eligible men who were offered MPT for BV and expressed interest in the qualitative study. Male experience of symptoms was an unexpected theme that did not reach saturation, and will be the subject of another study. We have also added the inability to reach saturation on this theme in the limitations.
“Male experience of symptoms was an unexpected theme that did not reach saturation, and will be the subject of another study” (Line 879-881)
2f) Comment
It is unclear to me what you mean by “explore consciousness” on line 113
2f) Response
We have replaced “explore consciousness” to “explore lived experiences” in line 128 to improve clarity for the reader.
2g) Comment
Line 177, the acronym JB appears for the first time… who is this person? Why was this person an appropriate person to conclude data saturation? Explain
2g) Response
Thank you for raising this. We have amended this in the manuscript by introducing relevant members of the research team (JB and CV) at an earlier point in the paper.
“RW met regularly with JB and CV, experienced social researchers adept in qualitative methods in the area of sexual and reproductive health, to discuss the interviews and emerging themes.” (Line 226-227)
2h) Comment
You conducted phone interviews about a potentially private/sensitive topic – was anything done to build trust?
2h) Response
RW is an experienced sexual health nurse accustomed to discussing sexual health matters with patients and participants and made a considerable effort to put participants at ease. Participants were also given multiple opportunities to ask questions, to decline participation or cease the interview. Men were reminded in the PICF and at the beginning of the interview that they did not need to answer anything they did not feel comfortable with. As participants were either actively participating in Step Up RCT, or had recently participated, they had developed trust in the research teams at Melbourne Sexual Health Centre.
We have added the following line to the manuscript to clarify this in the text also:
“Men were informed they did not need to answer any questions they were not comfortable with and could cease the interview at any point.” (Line 204-205)
2i) Comment
Line 175: Influence on what?
2i) Response
Thank you for highlighting this. We have clarified this in line 230.
“…including questions around the influence of uncertainty of infection in men on their willingness to accept MPT.”
3. Results
3a) Comment
Table 4 is difficult to read, also this isn’t a case study from what I can tell, so presenting the variation as text and explaining it will be better.
3a) Response
This table is intended to provide a snapshot of the complexity and differences in experiences among men that we feel is better achieved in a table than in text. We have provided a similar 3 case scenario table in a previous PLOS One paper exploring women’s experiences of BV and it was well received in the paper [2]. The case study format allows the provision of a summary of a single individuals overall experience and relates to a number of themes, particularly in case study 3 (who declined study participation in a similar trial years prior with the same partner, and accepted on this occasion). It is the authors preference to keep these descriptions in table format if possible but we have reformatted the table for easier readability. We have also reduced the wordcount within the case studies to keep the table as small as possible without losing the narrative of these participants experiences, which is intended to provide the reader with a clearer understanding of the diversity of men’s lived experiences across themes presented in the manuscript.
If the reviewers/editor feels that the table of case scenarios do not add any value to the paper, we can remove this table from the manuscript. Please note, if it is removed, we would need to reformat some aspects of the manuscript where the reader is referred to the cases studies.
The reformatted table (Line 312) currently occupies only one page if it is not embedded within text.
3b) Comment
Analysis needs some more work and cleaning up for example, line 231/232: how are 3.1 and 3.2 different? 3.2 seems more about manhood/perceptions of masculinity than “the supportive man” while 4.1.1 also speaks of “manhood” a bit differently.
3b) Response
Thank you for this feedback. We can see how 3.1 and 3.2 may be difficult to differentiate.
3.1 Speaks to the role of the relationship itself in influencing acceptance, whilst 3.2 speaks to men’s perceptions of what it is to be a man in relation to their partner or women more generally. 4.1.1 speaks of manhood in a different way as it is presenting the idea of the “masculine” version of manhood as a potential barrier to acceptance. We pick up on these differences throughout the discussion.
To improve the clarity of distinction between 3.1 and 3.2, we have changed the subtitle of 3.2 from “The supportive man” to “My responsibility as a man” (Line 531). We have also removed a portion of 3.1 that could be viewed as repetitive (Lines 508-515).
We feel that this feedback has significantly improved the clarity of these themes. Thank you.
3c) Comment
Page 16/17: Case 2: “This participant demonstrated extremely high levels of STI stigma and traditional masculinity”. Here ‘stigma’ and ‘traditional masculinity’ need to be contextualised and defined. You do it a bit in your discussion but these concepts can be defined in the methods and theory section.
3c) Response
Thank you for raising this point. In order to clarify the meaning of this in context, we have changed the wording in this case study as highlighted in blue below:
“Despite accepting treatment, this participant demonstrated an extremely judgmental attitude towards STIs and those who had experienced them, as well as demonstrating high levels of the type of “manly” masculinity described by all participants as a likely barrier to MPT acceptance. “(Table Four)
We have also added the lines below to the theory section of the manuscript to highlight the role of norms of masculinity earlier in the manuscript.
“Theories of gender and health argue that health-related beliefs and behaviours are a means for demonstrating masculinity and are therefore culturally understood symbols that can be leveraged to assert a particular identity or cultural norm (5–7) Traditional masculine ideals that prescribe stoicism, dominance, independence and self‐reliance (5–8) are increasingly identified as one of the most important socio-cultural factors influencing men’s health attitudes, behaviours and outcomes.” (Line 119-124)
3d) Comment
Line 650-653: From the data presented here, it seems to me that their sex lives DO matter to them
3d) Response
Thank you for your comment. The presence of female symptoms does not bother men as much as their partners response to them (embarrassment, shame and reduced self-esteem). Accordingly, we have slightly changed the wording of this line to improve clarity. The change is underlined below.
“This study has demonstrated that while the symptoms of BV often do have an impact on men’s sex lives this appears to be mainly due to the shame and embarrassment women feel, and men in this study demonstrated they are more concerned with the impact of symptoms on their partners self-esteem than their sex lives per se.” (Line 719-723)
3e) Comment
Table 2 “How would they like to receive information” – what information? Specify.
3e) Response
This line has been changed to the following (change in blue):
“How would they like to receive information about BV” (Table 2)
3f) Comment
Line 194, You write about JB and CV being experienced social researchers. This should come earlier when or before JB was first introduced
3f) Response
Thank you for highlighting this. We have amended this in the manuscript by introducing JB and CV earlier in the paper (please see earlier response 2g).
3g) Comment
Line 200, How were the 20 men chosen to be contacted? Were there only 20 who contacted you with interest in being in a study? When you stopped at 11, did you contact the remaining 9 to inform them why they were not contacted further?
3g) Response
As described in the response addressing maximum variation (2d), we have amended the manuscript to clarify that 20 men were eligible and all were contacted by RW.
Those who did not reply to the initial invitation SMS or withdrew consent were not followed up further as per study protocol and HREC approval. We have also amended the results section to clarify these remaining men did not respond to the invitation to participate and were therefore not followed up further.
“During the recruitment period, before it was decided data saturation had been met, 20 men were eligible for this study. All eligible men were contacted for interview. Of those contacted, 11 men were interviewed; 7 were recruited from the StepUp Pilot and 4 from the StepUp RCT. Of the remaining 9 men that were contacted, 8 did not respond to the SMS invitation and 1 decided to withdraw after consenting. These 9 men were not followed up further as per the study protocol and ethics approval.” (Line 260-261)
3f) Comment
Table 3. Did you mean “Average length of relationship”?
3f) Response
This is the median length of relationship, and the range. We agree it is currently made difficult for the reader by the table being split across two pages due to insertion directly under the paragraph in which it was mentioned as per submission guidelines.
3g) Comment
The list of themes and sub themes is unnecessary
3g) Response
Thank you for this feedback. We have removed this list.
3h) Comment
Check for repetition in the results
3h) Response
We believe that this may refer to the perceived repetition in the results in 3.1 and 3.2 and have addressed this in our earlier comment (3b). We have now clarified the difference between these two themes and removed some of the text that may have been viewed as repetitive.
Reviewer Two
1a) Comment
It would be interesting to know a bit more about what the Step Up Trial consisted of for the male partners, beyond the eligibility requirements. Was it treatment only or were there other aspects of the study (e.g. education).
1a) Response
Thank you for this feedback. We have added the below to describe the requirements of the Step Up Pilot and RCT within the manuscript.
“Within the Step Up studies, male partners of women being treated for BV were randomised to oral Metronidazole and a topical antibiotic cream applied to the penis twice a day for 7 days or current standard of care (female treatment only). Participants self-collected genital samples monthly for a follow up period of 3 months. All male procedures, including initial recruitment were able to be conducted remotely via phone and using post packs. To ensure consistency, all male partners were provided with the same information regarding the trial and BV at recruitment; that BV is a commonly occurring infection in women, that BV associated bacteria have been found on male genitals and that these bacteria may be exchanged during sex. No further education was provided. Men were also made aware that all answers in questionnaires were kept strictly confidential and not shared with partners.” (Line 150-160)
2a) Comment
Consent process: Did the study team require written/electronic informed consent or verbal consent? A bit more detail on the consent process in the text would be helpful.
2a) Response
Thank you for this feedback. We have addressed this point earlier in the response to Reviewer 1’s comments under subheading 2a.
3a) Comment
In the analysis, the authors state that they reached data saturation after 11 participants had been interviewed but, in the results section, it seems that the others who were not interviewed (the remaining 9 of the 20 contacted) were not interested in participating. Had data saturation not been reached, what would have happened?
3a) Response
Thank you for this question. Had data saturation not been met within this sample, interviews would have continued as participants were recruited to the ongoing Step Up RCT. We have added the line below to the manuscript to clarify this for the reader.
“If data saturation had not been met after 11 interviews, further participants would have been prospectively recruited from the men enrolled in the ongoing StepUp RCT.” (Line 262-264)
One area where saturation was not met was the experience of men with symptoms they attributed to BV. This was an unexpected theme and beyond the scope of the original research question and therefor will be the subject of a future paper. We have just received ethics approval to conduct interviews to explore symptomatic men’s experiences further.
For further elaboration on the limited ability to purposively sample for maximum variation, we invite the reviewer to see our response to Reviewer 1’s comment under subheading 2d.
4. Methods
4a) Comment
20-60 minute interviews seem quite short for lived experience research, what was the average length?
4a) Response
The average length was 39 minutes. We have added this to the manuscript:
“All participants chose the option of a telephone interview, which lasted between 20 to 60 minutes (average 39 minutes).” (Line 274)
4b) Comment
What was the sexual identification of the 1 participant who did not identify as heterosexual?
4b) response
This participant identified as bicurious, which is a heterosexual person who is interested in having a sexual experience with a person of the same sex.
This information and definition has been added to Table 3.
4c) Comment
Is there a better way to format the case scenarios? It was difficult to read side by side over several pages.
4c) Response
Thank you for this feedback. As per our earlier response to Reviewer 1, we have reformatted the table to improve readability.
4d) Comment
Regarding your point about local categories of illnesses and its impact on the disease and treatment experiences (and acceptance), I wonder if there is any literature about the perceptions of men regarding vaccination for HPV and about stigma related to HPV care seeking. This literature, if it exists, might be interesting to explore.
4d) Response
The reviewer’s comment inspired us to look at the literature regarding willingness of men to accept HPV vaccination in comparison to women, as this is recognised (among heterosexuals in particular) to be of greatest benefit for females. Therefore, there appear to be parallels between men’s willingness to accept MPT “for his partner” and accept HPV vaccination “to protect women”. We would like to thank the reviewer for this comment at this is an interesting parallel we had not identified, and the literature appears to reflect our own finding that the lack of perceived personal benefit is of great importance. We have therefore added the following lines to the discussion of our paper.
“Many participants identified that men, including themselves, may refuse MPT for BV due to the belief that treatment would be of no personal benefit. Similarly, a review of literature exploring HPV vaccination acceptability and intention to vaccinate among men demonstrated that this same belief that the vaccine would not directly benefit males was repeatedly cited as the primary reason men would decline HPV vaccination (9) Indeed, one study of college students in the USA demonstrated that only 38% of men would accept vaccination if they understood that this would protect their female partners from cervical cancer alone, compared to 78% that would accept the vaccine if there was the personal benefit of protection against genital warts (10). These findings support the finding that the lack of BV symptoms in men may represent a serious barrier to the success of MPT.” (Line 834-844)
4e) Comment
I also think that the finding about BV not being classified as a STI is important to think about when working out how to communicate with the public about treatment and decision making as well as the case of the man who had symptoms.
4e) Response
We also feel that this is a very important point for future communications regarding BV treatment. We have also added the line below to more clearly identify the importance of this finding.
“This finding will be important when considering how clinicians may communicate MPT for BV if it is found to be successful in reducing BV recurrence in women.” (Line 773-734)
As noted in response to reviewer one (2e) we plan to undertake further interviews specifically with men who feel they have had BV-like symptoms in a separate study.
