What this trial studies

This clinical trial investigates the effectiveness of semaglutide in treating obese infertile women aged 22-40 with polycystic ovary syndrome (PCOS). A total of 75 participants will be randomly assigned to receive either metformin, semaglutide, or a combination of both, alongside a calorie-restricted diet and physical exercise for 12 weeks. The primary focus is on weight loss percentage, while secondary outcomes include metabolic markers, ovulation rates, and pregnancy outcomes over a 24-week follow-up period. The study aims to provide insights into how these treatments can improve fertility and metabolic health in this population.

Who should consider this trial

Good fit: Ideal candidates are obese infertile women aged 22-40 who meet the diagnostic criteria for PCOS.

Not a fit: Patients with severe endometriosis, low ovarian reserve, or those unable to tolerate pregnancy and ovulation induction therapy may not benefit from this study.

Why it matters

Potential benefit: If successful, this study could enhance fertility and metabolic health in obese women suffering from PCOS.

How similar studies have performed: Other studies have shown promise in using similar approaches for managing PCOS and improving fertility outcomes.
