Title: A Prospective Randomised Study to Evaluate the Effect of Triggering Ovulation With GnRHa (Buserelin) and Low Dose hCG (Pregnyl) as Compared to the Use of Conventional Doses of hCG (Pregnyl)
Brief Summary: The purpose of this study is to possibly further improve the clinical outcome and explore the incidence of OHSS in patients, who have final oocyte maturation with GnRHa (Buserelin) in GnRH antagonist IVF/ICSI cycles

* Patients with \> 25 follicles on the day of triggering ovulation
B: Inclusion Criteria:

* Women undergoing embryo transfer following controlled ovarian hyperstimulation with a long GnRH agonist protocol, oocyte pick-up and ICSI.
* Embryo transfer performed on day 3.

Exclusion Criteria:
