Primary Outcome Measures:
  • number of retrieved oocytes [ Time Frame: at the ovarian puncture, 36 hours post HCG administration ]

Secondary Outcome Measures:

  • delivery rate [ Time Frame: 9 months later ]
  • number of obtained embryos [ Time Frame: 2 days after in vitro fertilization ]
  • duration of FSH administration [ Time Frame: at the end of ovarian stimulation usually after a mean of 12 days of administration ]
    number of days of administration

  • Total FSH dose [ Time Frame: at the end of ovarian stimulation usually after a mean of 12 days of administration ]
    daily dose x number of days of administration


Enrollment: 472

Study Completion Date: May 2011
Primary Completion Date: July 2010 (Final data collection date for primary outcome measure)
Arms Assigned Interventions
Active Comparator: Estrogen pre-treatment Drug: 17beta-estradiol
Pretreatment with 17beta-estradiol (Provames®, Aventis, Paris, France) was administered daily (2 mg twice a day) during the cycle preceding the IVF/ICSI cycle, starting 7 days before the predicted onset of menses and administered up until to the following Thursday after the occurrence of menses.
No Intervention: Control
The control group did not receive any pre-treatment.
