Role of luteal phase support on gonadotropin ovulation induction cycles in patients with polycystic ovary syndrome.

Objective: To evaluate the effect of luteal phase progesterone support on pregnancy rates in women with polycystic ovary syndrome (PCOS) who were treated for clomiphene citrate-resistant anovulatory infertility with ovulation induction and intrauterine insemination (OI/ IUI).

Study Design: This randomized study included 110 clomiphene citrate-resistant PCOS patients. All patients underwent ovulation induction with recombinant follicle-stimulating hormone and intrauterine insemination, up to 3 cycles, and were randomized into 2 groups: (1) luteal support with progesterone or (2) a control group. The main outcomes were clinical pregnancy rates and live birth rates per cycle.

Results: Demographic data were not different between the study and control groups. Cycle characteristics were found to be homogeneous between groups. A total of 38 pregnancies were achieved (15.5% pregnancy rate per cycle). The clinical pregnancy rate and live birth rate per cycle in progesterone supported cycles were 18.9% and 16.8%, respectively.

Conclusion: There might be a clinical benefit of luteal progesterone supplementation on OI/IUI cycles for women with PCOS. Although we did not reach a statistically significant difference between the 2 groups, luteal-supported cycles demonstrated a 6.7% higher clinical pregnancy rate and 6.1% higher live birth rate.
