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.

Immunological studies in patients with mumps orchitis.

Seventy patients with mumps orchitis were investigated. Serological tests for antitesticular antibodies, using four different techniques showed positive results in 25 patients. Antivirus antibodies were detected and they reached higher values during the remission period of acute cases.
