title: Sperm motility characteristics and pregnancy outcome of artificial insemination with husband's semen for male infertility.
abstract: What parameter of semen has influence on the pregnancy outcome of artificial insemination with the husband's semen (AIH) with washed sperm for male infertility was investigated. Two hundred fifteen cycles in 62 patients of AIH with washed sperm for male infertility were prospectively studied. We compared six parameters (total sperm count, motility rate, sperm motile efficiency (SME) both before and after washing) in pregnant and non-pregnant cycles. SME of washed sperm was significantly higher in the pregnant than in the non-pregnant cycles (241.0 +/- 68.0 vs. 169.5 +/- 80.0). There were no differences in other five parameters between pregnant and non pregnant cycles. SME, the parameter of sperm motility characteristics, of washed sperm is closely related to the outcome of AIH for male infertility. Sperm motility characteristics after washing may be one of the important indexes of the result of AIH for male infertility.
