Womb waves: could uterine contractions predict IVF success?

This study looks at whether the natural contractions of the uterus (called endometrial peristalsis) influence the chance of pregnancy in women undergoing frozen embryo transfer with hormone replacement therapy. Researchers will measure these contractions using ultrasound at three key times during the treatment cycle. The goal is to see if certain contraction patterns are linked to higher live birth rates, which could help doctors personalize embryo transfer timing.
