Could ovulation timing unlock more flexible fertility treatments?
NCT ID NCT07648381
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study looks at how the corpus luteum—the structure left after ovulation—affects hormones and the heart during a natural menstrual cycle. Researchers will take blood samples and perform ultrasounds on women with regular cycles to measure substances like progesterone and relaxin. The goal is to understand if inducing ovulation in smaller follicles could safely make frozen embryo transfer cycles more flexible.
