Summary
Brief summary (as posted)
The purpose of our study was to conduct a placebo controlled, double-blind randomized trial in chronic oligoovulatory or anovulatory , hyperandrogenic, infertility patients comparing the effects of adjuvant metformin plus clomiphene citrate to clomiphene citrate plus placebo on pregnancy rates and ovulation rates. We hypothesized that combining metformin with clomiphene citrate would result in higher ovulation and pregnancy rates in hyperandrogenic women who have chronic oligoovulation or anovulation as the sole etiology for their infertility and who have unknown responsiveness to clomiphene citrate.
