Abstract
Background: Intrauterine insemination (IUI) is one of the therapeutic approaches for infertility. The objective of this study was to evaluate DNA integrity and apoptosis role in success of IUI in both mild male and female factor infertility. Methods: Patients were divided into two groups: M (mild male factor; n=29) and F (female factor; n=31) undergoing single IUI. Ejaculates were analyzed and chromatin quality was assessed using chromomycin A3 (CMA3) staining. In addition, spermatozoal apoptosis was recognized using TUNEL assay. Statistical analyses were done using t-test and Mann Whitney test for sperm apoptosis and sperm chromatin by SPSS. Data were expressed in mean ± SD for variables. P < 0.05 was considered statistically significant. Results: Sperm concentration and progressive motility were higher in F than M group. Sperm with normal morphology were statistically similar in M and F infertile patients (32.7±15.6% vs. 35.5±9.07%, p=0.39). Sperm chromatin immaturity was higher in patients with mild male infertility, when compared with the other group (p < 0.01). Also, 32.0±5.6% and 30.8±6.1% of the spermatozoa showed signs of apoptosis in groups M and F, respectively (p=0.49). Very low (3.4%) clinical pregnancy rates were noticed in patients with mild male factor infertility Conclusion: Defect in sperm motility as well as high rates of DNA damage and apoptosis may be involved with very low rate of pregnancy outcomes in patients with mild male factor infertility. Therefore, it seems the application of IUI may have better outcomes in patients with female infertility compared to mild male factor infertility.
