Can a lower dose of fertility drug work just as well for IVF?
NCT ID NCT07346235
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study tests whether a lower daily dose (150 IU) of follicle-stimulating hormone (FSH) is as effective as a higher dose (225 IU) for women with normal ovarian reserve undergoing IVF. The main goal is to see if the lower dose leads to similar live birth rates while possibly reducing side effects and costs. About 440 women will take part in this phase 3 trial.
