Brief summary
To study the influence of different daily rec-FSH dosages (150 IU versus 300 IU), performed in the same patient in consecutive cycles, on the relation between FSH- and LH-receptors of the granulosa cells of the growing follicle.
Detailed description
This is a prospective cross-over study. Investigators want to study the effect of different dosages of recombinant FSH in the same patient on the expression of the FSH- and LH-receptors in the granulosa cells and on the endocrine milieu in the blood and the follicular fluid. An improved understanding of the mechanism leading to progesterone elevation might initiate a change in the ovarian stimulation approach, thereby not only preventing progesterone elevation and its negative consequences on ART (Assisted Reproductive Technology) outcome, but also improving individualization of the ovarian stimulation treatment according to the patients' characteristics.
Interventions
DRUGFollitropin beta injection 150 IU
Participants commence ovarian stimulation on day 2 or 3 of their menstrual cycle with a daily dosage of 150 IU rec-FSH. The dosage will remain constant throughout the course of the stimulation. From the morning of the 5th stimulation day, GnRH-antagonist will be administered daily to prevent LH-rise. As soon as ≥ 3 follicle of a size of 17mm are seen, 0.3 mg GnRH-Agonist will be administered for final oocyte maturation. During ovarian stimulation, follicle puncture procedures with the aspiration of follicular fluid will be performed at the following time: * one follicle on the morning of day 5, before the administration of the first GnRH-antagonist * one follicle of the size of 12 to 14 mm, when at least 2 to 3 follicles have reached a size of 12 to 14 mm * two follicles (= pre-ovulatory follicle) on the morning of the day of final oocyte maturation. Oocyte retrieval of all other follicles will be carried out 36 hours after injection of the medication for final oocyte maturation.
