Human anti-spermatozoa antibody seminal ELISA kit is designed for detecting in vitro quantitative levels of antibodies directed against anti sperm antibody (ASA, anti-spermatozoa antibody) using human seminal plasma. This assay has a minimum analytical sensitivity limit of 25.0 U/ml.
Mixture of spermatozoa proteins that are recognised by anti-spermatozoa antibodies are coated on the ELISA-plate.
Anti-spermatozoa antibody (ASA) are known to fight against man’s sperm in the blood, semen or vaginal fluids. These can cause an immune system response which can either damage or even kill sperm in the bodies of men or women. The use of anti-spermatozoa antibody is widely recommended in the diagnosis of immunological disorders of fertility.
Elevated levels of sperm antibodies come into contact with sperm they can make it very difficult or even impossible for the sperm to fertilise an egg (often referred to immunologic infertility). A women can produce sperm antibodies through an allergic reaction to the partner’s semen, whereas in men if the sperm comes into contact with his immune system this can lead to the production of sperm antibodies. Human ASA can also be applied for clinical practices to the diagnosis of infertility in men. Please note: the terms anti-sperm antibodies, anti-spermatozoa antibodies and sperm antibodies are equivalent.
All reagents supplied with this need to be stored at 2 °C – 8 °C, unopened reagents will retain reactivity until expiration date. Do not use reagents beyond this date.
