Abstract
Antisperm autoantibodies were determined in 16 men suffering from psychogenic anejaculation who underwent assisted reproduction treatments. Blood and semen samples were collected after transrectal electroejaculation and antisperm antibodies in serum and on the surface of motile spermatozoa were measured using the direct and indirect immunobead binding test. Five men (31%) were found positive for antisperm antibodies. The majority of antibodies were directed against the sperm heads. Surface antibodies were mainly IgA isotype whereas serum antibodies were IgG isotype. These results suggest that psychogenic anejaculation might be associated with increased incidence of antisperm autoimmunity.
