corifollitropin alfa + recFSH
corifollitropin alfa + hCG
Eligible participants will receive a subcutaneous (SC) injection of corifollitropin alfa (Stage 1a: 15mcg, Stage Ib/II: 30 mcg) the first, second, or third day after onset of a progestagen-induced withdrawal bleeding. If the follicle growth is insufficient, the participant will receive a second or third dose of corifollitropin alfa (Stage 1a: 15 mcg, Stage Ib/II: 20 mcg). As soon as the largest follicle reaches a size of ≥12 mm, the participant will start daily SC injections with FSH (Stage 1A: 50 IU, Stage II: 75 IU) the same day. A bolus injection of hCG (5000 IU) will be administered if at least one follicle is ≥18 mm and in total no more than two follicles ≥15 mm are observed.
