Summary The histochemical distribution of various hydroxysteroid dehydrogenases in human, term, foetal membranes has been investigated using the tetrazolium dye, Nitro-B.T. The trophoblastic layer was the most active, showing 3α-, 3β-, 11β-, 16β- and 17β-hydroxysteroid dehydrogenase activities, a pattern of activity similar to that of the placental villous trophoblast. The amniotic epithelium showed weak 3α-, 3β-, 16β- and 17β-hydroxysteroid dehydrogenase activity; weak 3α- and 3β-hydroxysteroid dehydrogenase activity was noted in the connective tissue layers. All activity demonstrated was N.A.D.-linked.
