What this trial studies

This interventional study aims to evaluate the effects of pulsatile intravenous administration of Follicle Stimulating Hormone (FSH) on women with obesity who are experiencing infertility. The study will compare the hormonal outcomes of pulsatile FSH treatment to conventional daily FSH injections, focusing on luteal phase progesterone excretion as the primary outcome. By using a crossover design, each participant will serve as their own control, allowing for a direct comparison of treatment effects across different cycles. The goal is to assess the potential of this innovative approach to enhance folliculogenesis and address reproductive hormone deficiencies associated with obesity.

Who should consider this trial

Good fit: Ideal candidates for this study are women with obesity (BMI between 30 and 40) who have been unable to conceive for at least six months and meet specific hormonal and reproductive criteria.

Not a fit: Patients with a clinical diagnosis of polycystic ovarian syndrome (PCOS) or those who do not meet the inclusion criteria will not benefit from this study.

Why it matters

Potential benefit: If successful, this treatment could improve fertility outcomes for women with obesity by correcting hormonal imbalances.

How similar studies have performed: While the approach of pulsatile FSH administration is innovative, similar studies have shown promise in addressing reproductive hormone deficiencies, suggesting potential for success.
