  Purpose
The proposal of this study is to evaluate the association between the achievement of ongoing pregnancy and hormonal levels on the first day after the period had stopped in rec-FSH/GnRH- antagonist cycles.

Primary Outcome Measures:
  • Ongoing pregnancy rate. [ Time Frame: 3 months ]

Estimated Enrollment: 90
Study Start Date: November 2009
Study Completion Date: May 2011
Primary Completion Date: February 2010 (Final data collection date for primary outcome measure)
Detailed Description:

Ovarian stimulation will be achieved by rec- FSH, Puregon® starting on day 2 of the cycle at a dose of 200 IU/day. The dose of rec-FSH remains unchanged during stimulation until day 10 of the cycle. If it is necessary to increase the dose of rec-FSH after 10 days of stimulation, or to decrease the dose of rec-FSH due to a risk of OHSS, the patient will be dropped out of the study.

To inhibit premature LH surge daily GnRH - antagonist (orgalutran 0,25mg ) is used from the morning of day 6 of stimulation.

Final oocyte maturation will be achieved by administration of 10.000 IU of HCG (Pregnyl®) as soon as ≥ 3 follicles ≥ 17 mm are present. E2 levels should not be criteria for HCG administration. Oocyte retrieval will be carried out 36 hours after HCG administration. Conventional IVF or ICSI will be carried out. Embryo transfer will be carried out day3 or day5 after oocyte retrieval.

Similar luteal support for all patients with vaginal administration of 600mg natural micronised progesterone in three separate doses (Utrogestan® 200mg 3xday) starting one day after oocyte retrieval will be used. Hormonal assessment (E2,FSH,LH,Progesterone) will be performed at initiation of stimulation, on the first day after the period had stopped and every 2 days until the day of HCG administration.
