Obstructive lesions of the genital tract in men

Obstructive lesions of the efferent and epididymal ducts in man were a common finding at necropsy. Although they demonstrated evidence of resorption of spermatozoa, they did not appear to be associated with the development of spermagglutinating antibodies in most cases. It is concluded that local spermiophagy within the genital tract in men is insufficient to lead to the development of antisperm autoallergy as detected by the tray agglutination test.
