title: Antisperm antibodies are more prevalent in men with low sperm motility.
abstract: Fifty-six men with low sperm motility (less than or equal to 40% of sperm with forward progression) who attended our infertility clinic were tested for antisperm antibodies (IgG and IgA) using the indirect immunobead test. Nineteen (34%) of these men were found to be positive (greater than 10% binding). This was significantly higher (P less than 0.01) than the incidence (5%) of antibodies in men who attended our infertility clinic with high sperm motility (greater than 40% of sperm with forward progression). It is concluded that significantly more men with low sperm motility have antisperm antibodies. The functional significance of these antibodies warrants further investigation.
