COOL-COS

All women will receive Letrozole, Clomiphene, and Corifollitropin Alfa for controlled ovarian stimulation

Group Type EXPERIMENTAL

COOL-COS

Intervention Type DRUG

Controlled ovarian stimulation will start on the second or third day of a menstrual cycle: Oral clomiphene citrate: 100 mg/day until the day of the triggering. Oral letrozole: 7.5 mg/day during the first 5 days of the controlled ovarian stimulation.

Corifollitropin Alfa: 100 mcg on the 3rd day of the controlled ovarian stimulation.

The triggering will be performed using leuprorelin 1 mg (subcutaneous).
