title: In vitro 16 alpha-hydroxylation of progesterone by testes of crab-eating monkey (Macaca irus): a characteristic of primates?
abstract: Radioactive 16 alpha-hydroxyprogesterone was obtained as one of the major metabolites of [14C]pregnenolone and progesterone by testicular homogenates of an adult crab-eating monkey (Macaca irus). 16 alpha-hydroxylation of progesterone occurred by incubation of testes of men and and the monkey, but not by those of rodents and other vertebrates examined.
