COOL-COS
EXPERIMENTALAll women will receive Letrozole, Clomiphene, and Corifollitropin Alfa for controlled ovarian stimulation
Interventions
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).
Eligibility Criteria
You may qualify if:
- Women scheduled to controlled ovarian stimulation for oocyte retrieval.
- Body mass index between 18 and 35 Kg/m2.
- Ultrasound scan up to the third day of a menstrual cycle with absence of a dominant and active follicle (follicle \>10mm and serum estradiol ≥ 40 pg/L).
- Signing an informed consent.
You may not qualify if:
- None
