What this trial studies

This clinical trial aims to evaluate the effectiveness of Myo-inositol supplementation in reducing resistance to Clomiphene Citrate in women diagnosed with polycystic ovarian syndrome (PCOS) who wish to conceive. The study is designed as a controlled, randomized, and double-blinded trial, where participants will be divided into two groups: one receiving Myo-inositol and levomefolic acid alongside Clomiphene Citrate, and the other receiving a placebo with levomefolic acid. The supplementation will begin at least one month prior to Clomiphene treatment and will continue until pregnancy is achieved or after six ovulatory cycles without success.

Why it matters

Potential benefit: If successful, this study could enhance ovulation induction success rates in women with PCOS, potentially leading to higher pregnancy rates.

How similar studies have gone: Previous studies have shown promising results with Myo-inositol supplementation in improving ovulation rates in women with PCOS, suggesting this approach may be effective.
