Brief summary

The current prospective observational pilot study aims to evaluate the endocrine profile of a single-injection protocol (single CFA + daily oral administration of CC).

Interventions

DRUGCorifollitropin alfa (CFA) 150 mcg + Clomiphene Citrate (CC) 100 mg/day from D1

On day 2 or 3 of the menstrual cycle or after 5 days of pill-free interval, a single injection of 150 mcg of CFA (Stimulation Day 1) will be administered.

DRUGClomiphene Citrate (CC) 100 mg/day from D1

On day 2 or 3 of the menstrual cycle or after 5 days of pill-free interval, the patients will start oral administration of Clomiphene Citrate 100/day continuing up to and including the day of ovulation triggering

DIAGNOSTIC_TESTMonitoring cycle

Scan controls and blood exams will be performed on stimulation days 1, 6, 8, 10 and, according to clinical needs, until trigger day.
