What the Study Found (In Plain English)
Published in Fertility and sterility (1999), this randomized controlled trial evaluating human clinical outcomes investigated: To evaluate whether pretreatment with metformin improves FSH-induced ovulation in women with clomiphene-resistant polycystic ovary syndrome (PCOS). Key clinical takeaway: By reducing hyperinsulinism, metformin determines a reduction in intraovarian androgens. This leads to a reduction in E2 levels and favors orderly follicular growth in response to exogenous gonadotropins.

Study Limitations & Caveats Before You Act
Clinical trials evaluate specific inclusion/exclusion cohorts under protocol-controlled conditions (Randomized Controlled Trial). Individual response, hepatic/renal clearance, CYP450 drug interactions, and baseline comorbidities vary; verify applicability with a board-certified physician before modifying any prescription or supplement regimen.
