Further study details as provided by Baskent University:

Primary Outcome Measures:
  • ongoing pregnancy rates [ Time Frame: pregnancy >12 weeks of gestation ]

Secondary Outcome Measures:
  • The effects of different coh regimens on outcomes [ Time Frame: 14 days after IUI procedure ]

Enrollment: 228
Study Start Date: May 2008
Study Completion Date: July 2009
Primary Completion Date: May 2009 (Final data collection date for primary outcome measure)
Arms Assigned Interventions
Sham Comparator: Single IUI
Single IUI will be carried on after 36-38 hours of HCG administration
Procedure: Intrauterine insemination (single)
Single IUI after 36-38 hours of HCG
Other Name: Group I
Active Comparator: Double IUI Procedure: Double intrauterine insemination
Double insemination after 18 and 40 hours of HCG administration.
Other Name: Grup II

Detailed Description:

Metaanalysis for the effects of double IUI demonstrates that effects of this procedure is not different from single IUI. It is known that nearly 25% of coh cycles is evident by monofollicular development.For this reason it is possible that this monofollicular cycles in the studies could decrease the effects of double IUI.

Inclusion criteria:

  1. Patients with unexplained infertility or mild male factor infertility whom admitted to the COH+IUI programme in our infertility unit.
  2. Female age <37 years old.
  3. Baseline FSH <12 mIU/L
  4. Total antral follicle count>6
  5. During the first three cycles of COH+IUI
  6. Minimum 2 follicles >16 mm at the day of HCG.

Primary outcome:

Ongoing pregnancy rates

Secondary outcomes:

The effects of different coh regimens (CC,FSH,CC+FSH)on the outcomes.
