Association between Pregnancy Rate of AID with Clomiphene Citrate and Follicle Size on hCG Day.

Objective: To investigate the association between follicle size on human chorionic gonadotropin (hCG) day and clinical pregnancy rate in cycles with clomiphene citrate. Methods: 212 infertile couples who accepted artificial insemination with donor semen treatment cycles were evaluated retrospectively in this study. They were divided into four groups according to the diameter of leading follicle on the day of hCG injection: group A (18-19.5 mm), group B (20-21.5 mm), group C (22-23.5 mm) and group D (above 24 mm). The pregnancy outcomes were compared. Results: The pregnancy rates of four groups were 24.39%, 14.29%, 18.18% and 7.14%. There was not significant difference among the four groups (P > 0.05). Conclusions: There is not association between pregnancy rate of AID in cycles with clomiphene citrate and follicle size on hCG day according to our present study. [ABSTRACT FROM AUTHOR]
