Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

This randomized trial was designed as a no-inferiority trial aiming to evaluate if the intensity of stimulation (a milder vs a more intense approach) may have an impact on the number of euploid embryos and the morpho kinetic parameters in advanced age women undergoing PGT-A with a PPOS protocol.

Study Groups

Review each arm or cohort in the study, along with the interventions and objectives associated with them.

Follitropin-delta 20 mcg/day from D1

Group Type EXPERIMENTAL

Follitropin-delta (Rekovelle) 20 mcg/day from D1

Intervention Type DRUG

On day 2 or 3 of the menstrual cycle, daily injections of 20 mcg of Rekovelle (Stimulation Day 1) will be administered. Scan controls blood exams are performed on stimulation days 6, 8, 10 and, according to clinical needs, until trigger day. The dose will be the same during the whole course of stimulation and no dose adjustments will be performed.

Follitropin-delta 15 mcg/day from D1

Group Type ACTIVE_COMPARATOR

Follitropin-delta (Rekovelle) 15 mcg/day from D1

Intervention Type DRUG

On day 2 or 3 of the menstrual cycle, daily injections of 15 mcg of Rekovelle (Stimulation Day 1) will be administered. Scan controls and blood exams are performed on stimulation days 6, 8, 10 and, according to clinical needs, until trigger day. The dose will be the same during the whole course of stimulation and no dose adjustments will be performed.
