Disorders of sex development generally present in the neonatal period with ambiguity of external genitalia. We report a very old male patient presenting at 75 years because of panhypopituitarism and a large nonsecreting pituitary macroadenoma secondary to long-standing primary hypogonadism due to 46,XX sex reversal disorder now first diagnosed. Sex development disorders may go unrecognised for the entire life span, despite infertility and long-standing primary gonadic failure may lead to uncommon complications.
Keywords: neonatal hypogonadism; pituitary gonadotrophic adenoma; sex reversal.
