  • Title: Prevalence, testicular function and seminal parameters in men with sperm antibodies.
    Author: Handelsman DJ, Conway AJ, Radonic I, Turtle JR.
    Journal: Clin Reprod Fertil; 1983 Mar; 2(1):39-45. PubMed ID: 6640473.
    Abstract:
    A prospective survey of 289 unselected men, attending a male infertility clinic (200 subjects) or as donors presenting for an artificial insemination programme (89 subjects) was performed. High titres of sperm agglutinating antibodies (greater than 1/32) were present only in a group of (6.5%) of infertile men but not in volunteer donors. Low titres occurred with similar frequencies (12%) in both groups. The sperm immobilizing antibody test was less sensitive and more specific but of no additional diagnostic benefit. Patients with high titres of sperm antibodies had evidence of testicular damage with decreased testicular volumes, elevated serum FSH and LH levels and reduced sperm density and motility whereas low titres were not associated with any testicular or seminal pathology. These data suggest a sub-group of infertile men have evidence of spermatogenic damage and impaired sperm function associated with high titres of sperm antibodies. Immunologic infertility in these men may reflect either an underlying autoimmune orchitis or a secondary immune reaction following testicular damage of various causes.
