title: Male pseudohermaphroditism due to 17-ketoreductase deficiency: report of a case without gynecomastia and without vaginal pouch.
abstract: A black adult subject, exhibiting complete virilization at puberty with psychological female orientation, was investigated. An older sister had similar physical habitus. Hormonal data showed an androstenedione/testosterone ratio greater than 1. This led us to the diagnosis of 17-ketoreductase deficiency, with possible genetic transmission of the defect.
