- Abstract
The aim of this study was to assess the correlation of sperm morphology with the intrauterine insemination ( IUI) outcome in patients with normal sperm concentration and motility. About 412 couples who underwent 908 IUI cycles were involved in the present study. A total of 110 clinical pregnancies were achieved with a pregnancy rate of 12.11% per cycle. The pregnancy rates per cycle were 7.60%, 12.67%, 13.62% and 13.13% in patients with <5%, 5-9%, 10-14% and >14% normal forms, respectively. The lowest pregnancy rate (7.60%) was obtained in the group with normal forms below 5%. However, this rate was not significantly different from other subgroups. Moreover, no pregnancies occurred in women >35 years old with normal sperm forms below 5%, in comparison with that in other subgroups of the same age. For women younger than 35 years old, no significant difference in pregnancy rate was observed in terms of different level of morphologically normal sperm. Our results show that for patients with normal sperm concentration and motility, IUI is recommended for first-line treatment when the woman is younger than 35 years, or morphologically normal sperm is ≥5%. IVF/ ICSI should be performed when the normal forms are <5% and female age is >35 years.
