ABSTRACT

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

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

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).

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.
