  Purpose
In this study,the investigators compared two protocols for controlled ovarian hyperstimulation in infertility patients requiring IVF. In the control group, the patient undergoes a standard antagonist protocol. In the study group, the administration of gonadotropins is stopped in the late follicular phase and replaced by low dose human chorionic gonadotropins. The primary endpoint of the study is the number of oocytes retrieved in both groups.

Condition Intervention Phase
Infertility Drug: human chorionic gonadotropin Drug: recombinant gonadotropins Phase 4

Study Type: Interventional
Study Design: Allocation: Randomized
Intervention Model: Parallel Assignment
Masking: Single (Investigator)
Primary Purpose: Treatment
Official Title: Among ICSI Patients Undergoing Antagonist Protocols With Recombinant FSH, Does Replacement of Recombinant FSH by 200 IU of hCG in the Late Follicular Phase Compared With Continuing Recombinant FSH, Result in a Similar Number of Oocytes?

Study Completion Date: November 2008
Primary Completion Date: January 2008 (Final data collection date for primary outcome measure)
Arms Assigned Interventions
Active Comparator: A
Patients undergo a standard antagonist protocol for in-vitro fertilisation, and are stimulated with recombinant gonadotropins.
Drug: recombinant gonadotropins
200 IU per day during controlled ovarian stimulation
Other Name: Puregon, NV Organon, Oss, The Netherlands
Experimental: B
Patients are undergo an antagonist protocol for in-vitro fertilisation and are stimulated with recombinant gonadotropins. When the patient has an estradiol value of 600 ng/L or more and when the patient has at least 6 follicles of 12 mm, the administration of gonadotropins is stopped and replaced by low dose human chorionic gonadotropins.
Drug: human chorionic gonadotropin
hCG 200IU in the late follicular phase
Other Name: Pregnyl, NV Organon, Oss, The Netherlands
