About this trial

This is a single-center, randomized, open-label, non-inferiority trial comparing two fixed daily doses of follicle-stimulating hormone (FSH): 150 IU versus 225 IU in women with predicted normal ovarian response undergoing in vitro fertilization (IVF) or intracytoplasmic sperm injection (ICSI) with a gonadotropin releasing hormone (GnRH) antagonist protocol. The primary objective is to determine whether the 150 IU dose is noninferior to the 225 IU dose regarding the cumulative live birth rate per initiated cycle. Secondary objectives include comparing oocyte yield, incidence of OHSS, treatment costs, and patient-reported outcomes.

Eligibility criteria

This trial does not accept healthy volunteers

Qualifiers

First or second IVF/ICSI cycle.

Planned GnRH antagonist protocol.

Disqualifiers

Predicted poor or high ovarian response (AMH <1.2 or >3.5 ng/mL; AFC <8 or >20).

Polycystic Ovary Syndrome (PCOS) according to Rotterdam criteria.

Severe endometriosis (Stage III-IV per ASRM).

Severe uterine abnormalities affecting implantation.
