Human anti-spermatozoa antibody serum ELISA kit can be used for measuring in vitro quantitative concentrations of antibodies directed ASA (anti-spermatozoa antibody, anti sperm antibody) in human serum samples. This assay has a minimum analytical sensitivity limit of 25.0 U/ml.
The ELISA-plate contains a mixture of spermatozoa proteins which can be recognised by anti-spermatozoa antibodies.
Anti-spermatozoa antibody (ASA) is present in both men and women, these have been found to lead to infertility. Infertility is regarded as a frequent problem in couples during their reproductive phase, generally, the occurrence of anti-sperm antibodies present in the serum or semen tend to be response for causing immuno-infertility. It is an ideal diagnostic tool for a wide variety of fertility related immunological disorders. Serum can be used as an indirect test for detecting antibodies against sperm.
The presence of anti-sperm antibodies in the serum will result in generating a positive test. Majority of these antibodies fight against male sperm in the semen, blood and vaginal fluids. They can trigger an immune response which has the ability to damage or even kill sperm in either men or women.
All reagents supplied need to be stored at 2 °C – 8 °C, unopened reagents will retain reactivity until expiration date. Do not use reagents beyond this date.
