ABSTRACT

Background:

The aim of our study was to assess the influence of intervals from sperm wash to intra uterine insemination on the IUI outcome.

Methods:

This was prospective study of 1125 cycles in Obstetrics and Gynecology Department of Baskent University Medical Faculty between January 2011 and December 2011.

Results:

In totally 1125 cycles IUI performed within < 30 minute in 202 cycle, 30-59 minute in 367 cycle, 60-89 minute in 381 cycle, 90-119 minute in 114 cycle, 120-180 minute in 61 cycle. Pregnacy rate was %4.5,%7.9,%11,%8.8, ve %11.5 respectively. We reanalyzed <30 minutes and other groups again we found that the difference reached statically significant level (%9.5 vs %4.5)(p: 0.01). In good prognostic patients with total motile sperm count was ≥ 10x106, pregnancy rates were lower in patients whose inseminated in <30 minute than the others (%10.1 vs %5.2) (p: 0.024).

Conclusion:

The results of our study showed that if a washing sperm can be incubated minimum 30 minute at 37 C the pregnancy rate is optimum. The longer period up to 180 minute doesn’t compromise the pregnancy rate.
