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.

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.
