Can weight management plus hormones reverse precancerous uterine changes and preserve fertility?

NCT ID NCT05316493

First seen Jun 27, 2026 · Last updated Jun 27, 2026

Summary

This study is for overweight or obese women aged 18–45 with atypical endometrial hyperplasia, a precancerous condition of the uterine lining. Participants will receive either a levonorgestrel-releasing IUD (Mirena) or megestrol acetate pills, combined with a weight management program including diet and exercise guidance. The goal is to see if this combination can reverse the abnormal cells and allow women to later become pregnant.

What this could lead to
If successful, this approach could help obese women with precancerous endometrial changes avoid hysterectomy and preserve their ability to have children.
