Weight-Loss drug may boost IVF success for overweight women
NCT ID NCT07242534
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study tests whether taking semaglutide (a weight-loss medication) for 12 weeks before starting IVF can lead to better-quality embryos in overweight or obese women. About 62 women aged 38 or younger with a BMI between 27 and 40 will be randomly assigned to receive semaglutide or no pre-treatment. The goal is to see if the drug improves the number of good-quality blastocysts available for freezing.
