Study on serum sperm agglutination in cases of unexplained infertility. Indian Journal of Pathology & Microbiology. 1998 Jul; 41(3): 343-50http://imsear.searo.who.int/handle/123456789/72849In our study we investigated 100 couples of unexplained infertility in order to detect the presence of anti-spermatozoal antibodies. Both auto-immunity and Iso-immunity have been found responsible in 12.5% of couples of primary infertility & 10% of couples of secondary infertility. As many as, 21% of cases of unexplained infertility were attributed to presence of antibodies in sera of infertile couples. Here, we highlight the importance of anti-spermatozoal antibodies testing in the first instance itself in cases of unexplained infertility.engAgglutination TestsAutoantigens --bloodFemaleHumansInfertility, Female --bloodIsoantigens --bloodMaleSpermatozoa --immunologyJournal Article
