What this trial studies

This study investigates the effectiveness of combining letrozole and clomiphene citrate compared to using letrozole alone in treating infertility in women with polycystic ovary syndrome (PCOS). PCOS is a common endocrine disorder that often leads to anovulatory infertility. The study aims to evaluate whether the combination of these two medications can improve ovulation rates and pregnancy outcomes. Participants will be women diagnosed with PCOS who have been unable to conceive after a specified period of regular unprotected intercourse.

Who should consider this trial

Good fit: Ideal candidates for this study are women under 35 years old with a diagnosis of infertility and PCOS based on the Rotterdam criteria.

Not a fit: Patients with unexplained infertility or other conditions causing chronic anovulation may not benefit from this study.

Why it matters

Potential benefit: If successful, this approach could enhance ovulation induction and increase pregnancy rates in women with PCOS.

How similar studies have performed: Previous studies have shown varying success with similar ovulation induction approaches, but this specific combination is being evaluated for the first time.
