NCT ID NCT07496294
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study compares two common progesterone treatments (oral dydrogesterone vs. vaginal micronized progesterone) for women going through menopause. All 200 participants will use an estradiol gel and be randomly assigned to one of the two progesterone options. The goal is to see which one better relieves symptoms like hot flashes and night sweats while keeping the uterus healthy. Results may help doctors choose the best hormone therapy for each woman.
