Progesterone after IUI: a simple step to more live births?
NCT ID NCT05080569
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study tests whether giving progesterone (a hormone) after intrauterine insemination (IUI) with mild ovarian stimulation increases the chance of a live birth. About 1,000 couples with unexplained infertility will take part. The goal is to see if this simple support can improve pregnancy rates and reduce miscarriage risk.
