TURNER'S SYNDROME in its most common form is a congenital disorder appearing in phenotypic females. It is characterized clinically by short stature, gonadal dysgenesis, sexual infantilism, and various somatic anomalies. A counterpart of this disorder in phenotypic males has been reported much less frequently and is not universally considered to be related to the female entity. In an effort to further define this syndrome in the male and its relationship to Turner's syndrome in the female, the present case is reported with a current review and summary of the literature. Report of Case A 13-year-old white boy was admitted to Ohio State University Hospital on Sept 6, 1964 for evaluation of growth retardation. The patient had had undescended testicles since birth. At age 11 an operation was performed and a 1 cm gonad was found high in each inguinal canal. These were brought into the scrotum at that time.
