Premature luteinization in patients undergoing IUI can occur in up to 24% of cycles. These patients, according to recent data, have a lower pregnancy rate than controls. The possibility to avoid premature luteinization with GnRH antagonist may restore the chances of achieving a pregnancy in these women.

Primary Outcome Measures:
  • Pregnancy rate [ Time Frame: 2 weeks after intervention ]

Secondary Outcome Measures:
  • premature luteinization [ Time Frame: at the time of intervention ]

Enrollment: 662
Study Start Date: October 2008
Study Completion Date: March 2011
Primary Completion Date: December 2010 (Final data collection date for primary outcome measure)
Groups/Cohorts Assigned Interventions
Patients with premature lutenization (progesterone >1,2 ng/ml) who did not get pregnant during the first IUI underwent a second IUI.
Drug: Ganirelix
Ganirelix 0.25mg s.c every 24 h starting stimulation day 6
Other Name: Orgalutran
Patients without premature lutenization (progesterone >1,2 ng/ml) underwent a only one IUI.

Detailed Description:
The purpose of this study was to investigate whether a subset of patients benefits from GnRHa administration during IUI. PL was tested for in patients who were undergoing artificial insemination procedures, and the effect of GnRHa on PR in patients who
