E.N.D.E.A.V.O.R.: An Exemestane Needed Dose Efficacy and Verification as an Ovulation Induction Regimen Study

The goal of this clinical trial is to learn if study drug exemestane will increase chances of ovulation for patients with polyendocrine metabolic ovarian syndrome (PMOS, formerly called polycystic ovary syndrome (PCOS)). It will also learn about side effects of study drug exemestane in this study population. The main questions it aims to answer are: Does exemestane lead to ovulation for patients with polyendocrine metabolic ovarian syndrome (PMOS- formerly called PCOS)? Researchers will compare exemestane to a placebo (a look-alike substance that contains no drug) to see if exemestane helps PMOS patients ovulate. Participants will: Take exemestane or a placebo every day for 5-10 days Visit the clinic three times for ultrasounds, labs, and to answer questions about side effects. If they become pregnant during this study, they will tell us how their pregnancy went after the study via a registry online.
