Testicular germinal cell antibodies were found in 44 of 59 patients with lepromatous leprosy and in 4 of 10 patients with tuberculoid disease. A similar pattern was found in 12 of 262 controls and normal subjects. The antibody was found to be of the IgG class and 40 of 49 of these antibodies were shown to be complement fixing. Spermatozoal antibodies were detected in 12 patients, but no ovarian antibodies were found in any specimen. There was no close correlation between erythema nodosum leprosum and testicular antibodies. It was found that the characteristic of the testicular antibody in leprosy was its ability to be absorbed by Mycobacterium BCG suspension suggesting that this is another antibody induced by infection. A similar fluorescent pattern was seen in some patients who did not have leprosy, but in these cases, it could not be abolished with BCG. It is concluded that autoimmunity may be 1 of the factors involved in the pathogenesis of orchitis in leprosy.
