ABSTRACT
Hyper-immunization of male mice with human LDH-C4 evoked autoimmune reactions illustrated by the loss of LDH activity, associated histopathological changes in testes and epididymis and induction of sterility in mice. This was substantiated by the altered morphology of sperm mitochondria and plasma membrane, and by reduced number of cytoplasmic droplets as observed by electron microscopy. However, the presence of lymphoblasts and other lymphoid cells in testes indicated that the testicular damage is accentuated by activated T lymphocytes. It is concluded that immunization with human LDH-C4 produces lesions in mouse testis and epididymis, which are similar to experimentally induced autoimmune orchitis.
