Functional role of spermagglutinating antibodies in men

The presence of spermagglutinating antibodies in blood and semen has been associated with reduced fertility in men. In this study 203 men were screened for infertility. An antibody measurement was performed on the blood and semen of each patient. Each semen specimen was also examined for spontaneous agglutination. Twelve patients with a positive reaction in the blood underwent a sperm-cervical mucus contact test. We have attempted to correlate the findings in blood with the observed functional results in semen and cervical mucus. We believe that these simple tests should be included in the infertility work-up in order to determine the presence of immune infertility.
