Phase 4
Recruiting
Conditions
Fertility
Interventions
Drug: Follitropin-delta (Rekovelle) 20 mcg/day from D1
Drug: Follitropin-delta (Rekovelle) 15 mcg/day from D1
Registration Number
NCT06154083
Lead Sponsor
Fundación Santiago Dexeus Font
Brief Summary

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.
