IgM antibodies , because of their large size, are rarely found in semen, while IgA and IgG antibodies are thought to have greater clinical importance and are both present in semen. Once sperm antibodies have forme these antibodies bind to the proteins (antigens) on the sperm hea mid-piece or tail and can affect sperm in several different ways.

The presence of antisperm antibodies (ASA) in the ejaculate is an immune cause of male infertility. There exist some treatment options to become a father in spite of having ASA in the semen. Men or women with high levels of sperm antibodies have significantly reduced fertility.

In this laboratory we use the mixed antiglobulin reaction, which enables us to specifically detect sperm -bound antibodies. Any of a group of antibodies produced against four distinct components of spermatozoa ( sperm cells). Carbone DJ Jr, Shah A, Thomas AJ Jr, Agarwal A.

As of yet, the effect that anti- sperm antibodies have on female fertility is little understood. In fact, both men and women can be affected by the presence of anti- sperm antibodies in their system. In the case of women, on whom we are focusing here, these antibodies are present in the vaginal fluids.

Neither the proportion of sperm in the ejaculate antibody-bound nor the regional specificity of binding of individual classes to the sperm surface can be determine however. Mixed Agglutination Reaction. Within the male reproductive system, the sperm cells should be protected by the immune system by a blood barrier.
