About this trial

Ovarian stimulation (OS) is a key component of IVF, aimed at increasing oocyte yield and improving embryo development potential. While early protocols relied solely on FSH, newer approaches incorporate hMG and LH-based stimulation, allowing more individualized treatments for specific patient populations. Evidence suggests that hMG and recombinant FSH (rFSH) have comparable effectiveness in stimulation outcomes, and current guidelines support the use of both. However, the impact of different gonadotropins on embryo quality remains unclear, with mixed findings across protocols. Given the increasing use of combined rFSH and hMG and the limited data in PPOS protocols, this study proposes a randomized controlled trial to compare embryo quality between two different rFSH-hMG dosing strategies.

Trial design

Design model

Parallel

Treatments tested in this trial

  • 10 mcg of follitropin-delta + 150 of hMG

    Drug

    On day 2 or 3 of the menstrual cycle, daily injections of 10 mcg of Rekovelle + 150 IU of Menopur (Stimulation Day 1) will be administered. Scan controls and blood exams will be performed on stimulation days 6, 8 and on trigger day. Further blood exams will add according to clinical needs. The dose will be the same during the whole course of stimulation and no dose adjustments will be performed.

  • 5 mcg of follitropin-delta + 225 of hMG

    Drug

    On day 2 or 3 of the menstrual cycle, daily injections of 5 mcg of Rekovelle + 225 IU of Menopur (Stimulation Day 1) will be administered. Scan controls and blood exams will be performed on stimulation days 6, 8 and on trigger day. Further blood exams will add according to clinical needs. The dose will be the same during the whole course of stimulation and no dose adjustments will be performed.
