The effect of elevated serum progesterone during ovulation induction in in vitro fertilization-embryo transfer.

Abstract：

OBJECTIVE:Our purpose was to determine whether elevated progesterone (P) during ovulation induction in IVF-ET cycles is a poor prognostic factor for achieving pregnancy. DESIGN:We retrospectively reviewed 672 consecutive IVF-ET cycles in which ovulation was performed using luteal LA downregulation and hMG. SETTING:The ART program at the Brigham & Women's Hospital, a tertiary care institution, was the study setting. MAIN OUTCOME MEASURES:Patients were divided into groups by serum P levels at baseline, on stimulation day 5, on the day of hCG injection, and, on the day after hCG injection and the following parameters were compared: duration of luteal LA treatment, number of ampoules of hMG used, estradiol (E2) levels, number of follicles > or = 12 mm, number of follicles > or = 15 mm, number of oocytes, number of normal embryos, number of polyspermic embryos, fertilization rate, implantation rate, and clinical and ongoing/live birth pregnancy rates. RESULTS:Based on serum P level, patients were divided into three groups: Group I, < or = 0.31 ng/ml (conversion factor to SIU, 3.180); Group II, and > 0.3 and < 1.0 ng/ml and Group III, > or = 1.0 ng/ml. Measureable P at baseline was associated with a higher cancellation rate, but no difference in other cycle outcome parameters. Progesterone > 0.31 ng/ml on stimulation day 5 was associated with a higher fertilization rate in Groups II and III, but there was no difference in the clinical pregnancy or ongoing/live birth rates among the three groups. Based on P on the day of hCG administration, Groups II and III had significantly more oocytes and higher fertilization rates than did Group I, however, clinical pregnancy and ongoing/live birth rates were not significantly different. On the day after hCG, there was a trend toward a higher clinical pregnancy rate in Group III, which had younger patients, better follicular recruitment, and more embryos than Groups I or II, but these differences did not reach statistical significance. CONCLUSIONS:Serum P > 0.31 ng/ml during ovulation induction reflects good follicular recruitment, and is not a predictor of IVF outcome.
