Does different subfertility etiology affect pregnancy rates in intrauterineinsemination cycles?

BACKGROUND/AIM: To investigate the relationship between subfertility etiologies and success rates in controlled ovarian stimulation and intrauterine insemination (COS–IUI) cycles.

MATERIALS AND

METHODS

The medical records of 218 couples who applied to a university-based fertility center were analyzed retrospectively. Detailed infertility examination data and pregnancy outcomes were compared according to different subfertility etiologies. The study groups with regard to subfertility etiologies were minimal–mild endometriosis, unexplained infertility, and mild male infertility. The primary outcome measure was live birth rate.

RESULTS

There were no statistically significant differences between the groups regarding demographics except for total motile sperm count. Live birth rates in the male infertility group were comparable to the endometriosis and unexpected infertility groups (6.6%, 11.9%, and 10.3%, respectively; P = 0.63).

CONCLUSION

The success rate of the mild male subfertility group following COS–IUI cycles for live birth rates was similar to those of the endometriosis and unexplained subfertility groups.
