Further study details as provided by Clinic and Research Center in Human Reproduction Roger Abdelmassih:

Primary Outcome Measures:
  • Comparative response to ICSI cycles with GnRH agosnist and cetrotide [ Time Frame: 16 months ]

Secondary Outcome Measures:
  • Compare number of oocytes retrieved, injected and fertilized, embryos transferred, and clinical pregnancy and miscarriage rates in both groups [ Time Frame: 16 months ]

Enrollment: 2005
Study Start Date: September 2005
Study Completion Date: December 2006
Detailed Description:
160 women were equally divided between a GnRH antagonist protocol (Group 1) versus a GnRH agonist protocol (Group 2) in ICSI cycles. The trial was conducted between September 2005 and December 2006. The mean age in both groups was 32 (range 22-40). The main outcome measures were the number of oocytes retrieved, injected and fertilized, embryos transferred, and clinical pregnancy and miscarriage rates.
