About this study

Gonal-F® (follitropin alfa) is a recombinant FSH without LH activity, while Menopur® contains both LH and hCG. The MEGASET trial compared Menopur® and Gonal-F® in GnRH antagonist cycles with SET, showing similar efficacy. A subsequent study (MEGASET-HR) in high responders found ongoing pregnancy rates of 35.5% for Menopur® and 30.7% for Gonal-F®, with a lower early pregnancy loss for Menopur® (14.5% vs 25.5%). Telomere length (TL) in oocyte cumulus cells (CC) correlates with oocyte quality and embryo outcomes. This study aims to assess whether stimulation type (hMG vs. Gonal-F) affects TL in CC and subsequent blastocyst development. A randomized, open-label, cross-over study in normo-responders will analyze telomere length, embryo quality, and hormonal markers.
