Influence Of Teratozoospermia On Intrauterine Insemination Outcomes

Although sperm morphology criteria are clearly defined, there are still slight differences among laboratories; moreover, the influence of teratozoospermia on the results of intrauterine insemination is not still clear. We have examined the influence of abnormal semen morphology on clinical pregnancy rate (CPR) in intrauterine insemination cycles with conjugal fresh semen, in 626 cycles between January-2011 and October-2012. We conducted two study groups, according to the severity of the teratozoospermia (cut off 4 %). Differences were statitiscally significant between the two groups. We have analyzed the results by diagnostic groups: male factor, unexplained infertility, ovulatory, and other factors. When the results were analyzed by diagnostic groups, only the male factor group proved similar results. According to our results, insemination with semen with severe teratozoospermia is not efficient and other options, such as ICSI, should be considered.
