Ovaries of two goats with persistent corpus luteum were studied by histochemical methods. Lutein cells showed moderate alkaline phosphatase and acid phosphatase activity associated with strong delta 5-3beta-hydroxysteroid dehydrogenase and succinic tetrazolium reductase activity. The results are interpreted as an indication that the corpus luteum was functioning.
