Relationship between serum progesterone concentration and top quality embryo rate.
With a decrease in the TQE rate, the serum progesterone concentration increased progressively. When serum progesterone levels were within the interval 2.0–2.5 ng/ml and >2.5 ng/ml, the TQE rate was significantly lower than the progesterone level < 1.0 ng/ml. In each group, values with different superscript letters differ significantly (P<0.05).

Top quality embryo rate according to different serum progesterone concentration cut-point on the day of hCG administration.
(A) progesterone cut-point, 1.5 ng/mL; (B) progesterone cut-point, 2.0 ng/mL; (C) progesterone cut-point, 2.5 ng/mL. The TQE rate was significantly different (P <0.05) between serum progesterone levels < 2.0 ng/ml and >2.0 ng/ml.
