The Effect of Intervals from Sperm Wash to Intra Uterine Insemination (IUI) Time on Pregnancy Rate

Background: The aim of our study was to assess the influence of intervals from sperm wash to intra uterine insemination on the IUI outcome. Material and 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 (%4.5 vs %9.5)(p: 0.01). In good prognostic patients with total motile sperm count was 3 10x106, pregnancy rates were lower in patients whose inseminated in <30 minute than the others (%5.2 vs %10.1)(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.
