Exenatide
Exenatide is an injected medicine that acts like GLP-1, a gut hormone released after eating. It slows the stomach, lowers appetite, and helps the body handle glucose. Exenatide was the first GLP-1 drug cleared for type 2 diabetes.
A woman with PCOS (polycystic ovary syndrome, now also called PMOS) may already be taking it for weight and blood sugar. In a trial of 60 women with PCOS and few ovulations, 86 percent ovulated on exenatide with metformin, against 29 percent on metformin alone.1
Most such trials used bleeding as a stand in for ovulation. The effect on true ovulation stays unclear.2
