Immunologic studies of male infertility.
The immunological basis of male sterility, as previously described, is related to alterations of spermatogenesis or impairment of seminal plasma formation. Both may be developed independently or may be related. Acute or subacute lesions of the genital tract or gonads may be more closely related to the presence of autosensitization than are chronic inflammatory processes or endocrine diseases of the testis. Oligo- or azoospermia may reflect the destruction of cells or halting of spermatogenesis. Immobilization and agglutination of sperm cells would depend predominantly on an allergic reaction that originates in the adnexal glands. Antibodies against testis do not affect adnexal glands but may immobilize epididymal spermatozoa, whereas antiseminal plasma antibodies react only with adnexal glands and seminal spermatozoa, but not with testicular cells. The pathogenic role of detectable antispermatic antibodies in sterile male or female patients are not sufficiently clarified. Their presence apparently correlate with unexplained cases of infertility, but this does not necessarily mean that they are specifically responsible for this abnormality; furthermore, they might be only an epiphenomenon of the immunological process involved.
