Spermatogenic antibodies are antibodies to normal semen and sperm produced by the immune system for various reasons that have not yet been identified. Once sperm enters the body, it is recognized as an antigen by the immune system and the sperm is swallowed up by the corresponding antibodies to prevent the normal meeting and union of sperm and egg, resulting in infertility. If you have unexplained infertility symptoms, it is best to check whether there are spermogenic antibodies in your body that are affecting normal conception, and those who are positive for spermogenic antibodies need to be treated promptly with hormonal drugs for systematic treatment to suppress the immune response and reduce the titer of the original spermogenic antibodies in your body to reduce the production of new antibodies.
