Male pseudohermaphroditism can be caused by absent mullerian regression, inadequate
synthesis of testosterone, inadequate synthesis of dihydrotestosterone, or ardrogen
receptor deficiency. Defects in either the production or the action of androgenic steroids
knave been demonstrated to cause pseudovaginal perineoscrotal hypospadias, a syndrome
of male pseudohermaphroditism. This is mostly caused by a deficiency of 5¥á-reductase,
which controls the conversion of testosterone to 5¥á-dihydrotestosterone.
We report a case of male pseudohermaphroditism due to 5¥á-reductase deficiency who
was born with ambiguous genitalia and was reared as female.
