Jump to content. An antisperm antibody test looks for special proteins antibodies that fight against a man's sperm in blood, vaginal fluids, or semen. The test uses a sample of sperm and adds a substance that binds only to affected sperm. Semen can cause an immune system response in either the man's or woman's body. The antibodies can damage or kill sperm. If a high number of sperm antibodies come into contact with a man's sperm, it may be hard for the sperm to fertilize an egg.

IBT allows the determination of the antibody class attached to spermatozoa, the localization on the spermatozoa, and the proportions of spermatozoa coated with antibody [ 14 ]. The immunoglobulin class detected can be of clinical importance Fig. These adjustments are occasionally necessary if the sample is oligozoospermic or asthenozoospermic. The IBT can also be conducted indirectly on reproductive fluids such as seminal plasma, follicular fluid, cervical mucus, as well as serum. The intra-assay reproducibility of the indirect IBT was evaluated by testing aliquots of ASA-positive sera from two patients against the same donor sperm sample.

The presence of antisperm antibodies ASA in the ejaculate is an immune cause of male infertility. The adhesion of antibodies to sperm affects their motility , making the sperm's journey to the egg highly difficult or even impossible. There exist some treatment options to become a father in spite of having ASA in the semen. An antibody, also known as immunoglobulin , is a substance produced by the immune system that identifies and attacks strange substances.
