Step-down approach and late follicular phase progesterone level
The study will be performed using the stimulation medication Gonal-F which is a recombinant FSH-preparation. Due to application as pen-device, it allows reduction of the stimulation dosage in steps of 12.5IU.
It is important to evaluate the dynamics of progesterone-rise after final oocyte maturation, as this dynamic might also have an influence on the receptivity of the endometrium.

| Label | Type | Description | Intervention Names |
|---|---|---|---|
| Control group | Active Comparator | Follicle stimulating Hormone will be applied, starting from day 3 of the cycle, the dosage will be choosen between Gonal F 150 - 225 IU, according to the ovarian reserve parameters (13). The stimulation dosage will remain unchanged until the criteria for final oocyte maturation are met (≥ 3 follicles of ≥ 17 mm). |
|
| Study group | Experimental | Follicle stimulating Hormone will be applied, starting from day 3 of the cycle, the dosage will be choosen between Gonal F 150 - 225 IU, according to the ovarian reserve parameters (LaMarca et al.). As soon as ≥ 3 follicle of a size of 14mm are seen, the stimulation dosage will be reduced daily by 12.5 IU recFSH until the criteria for final oocyte maturation are met (≥ 3 follicles of ≥ 17 mm). |
