GLP-1 receptor agonists (semaglutide, tirzepatide, liraglutide) produce significant weight loss (6–30%+ TBWL) and improve fertility outcomes (spontaneous conception, IVF pregnancy rates) in women with obesity and PCOS when used in the preconception period.

If you have obesity and are trying to conceive, GLP-1 medications (like Wegovy or Zepbound) are highly effective for weight loss and improving fertility, especially if you have PCOS. You must stop taking them 2 months before you try to conceive to ensure the drug is out of your system. Work with your doctor to manage side effects and costs.

GLP1-RAs reduce food cravings, appetite, and “food noise” and improve insulin sensitivity and satiety, all of which lead to significant weight loss, ranging from 6 to 30% of starting total body weight or greater... GLP-1 RAs can reverse polycystic ovary morphology and decrease serum concentrations of androgens... Elkind-Hirsch et al. illustrated enhanced menstrual regularity and improved rates of conception in women suffering from overweight or obesity with PCOS treated with GLP-1 RAs in the preconception period
