Lactate dehydrogenase C4 in male sex accessory glands of normal mice and in testes of sex-reversed mice.

Lactate dehydrogenase (LDH) C4 activity was observed in testis extracts of sex-reversed mice (Sxr) and in male sex accessory gland (seminal vesicle and prostate) extracts from C3H/He and C57BL/Go mice. These results reflect either (1) the presence of low concentrations of germinal cells in these tissues; or (2) the synthesis of LDH-C4 by somatic cells in Sxr testes and normal male sex accessory glands.
