Effect of Post-Wash Total Motile Sperm Count on the Pregnancy Rate of Infertility Patients Undergoing Intrauterine Insemination

Intrauterine insemination (IUI) is one of the most important infertility treatments. Infertility is failure to establish pregnancy (>12 months) with regularly unprotected sexual intercourse. Post-wash total motile sperm count (TMSC) vaguely defined as a predictor of IUI pregnancy rate. The minimum value required is also not clear. This study aimed to further define the relationship and determine the minimum recommended value to achieve a satisfactory IUI pregnancy rate.

Post-wash TMSC is predictive of IUI success. No optimal cut-off could be identified. In conclusion, post-wash TMSC is highly suggested as a quantitative predictor along with others in counseling and informed consent. The recommended threshold value is >3 x 106.
