Outcome of IUI Based on Sperm Morphology in Cases of Unexplained and Male Factor Infertility.

To evaluate the effects of sperm morphology on the success rate of IUI. This was a prospective study of 200 couples who underwent IUI in order to improve the likelihood of conception. The patients were divided into 2 groups, one consisting of 100 patients with a normal sperm morphology of ≤20%, and the other consisting of 100 patients with a normal semen morphology of >20%, and an otherwise normal semen analysis. A total of 59 clinical pregnancies were obtained for a pregnancy rate / cycle of 10.5%. No significant differences were found between the two groups examined. There are no substantial differences in the success of intrauterine insemination when normal sperm morphology in semen analysis is more than 20% compared to when it is less than 20%.
