Congenital lipoid adrenal hyperplasia results in deficient virilization of genetic male infants, indicating that gonadal testosterone biosynthesis is impaired in such patients. In order to better define the characteristics of the gonadal lesion, we studied a Japanese genetic male infant with congenital lipoid adrenal hyperplasia who underwent bilateral orchiectomy at 14 months of age. The basal serum testosterone was low before and after orchiectomy (6.6 +/- 1.1 vs. 9.5 +/- 1.3 ng/dl), though it was higher at 9 days of age (30 ng/dl). A stimulation test with human chorionic gonadotropin at 12 months of age yielded no testosterone response (7----less than 5 ng/dl). At the time of the surgical intervention, the external genitalia were completely female but Wolffian duct derivatives (epididymides and vasa deferentia) were well developed. The microscopic examination of the testes revealed an increased number of Leydig cells which were filled with abundant lipoid material.- The above data demonstrate that the fetus produced a sufficient amount of testicular testosterone for a male Wolffian duct development. This indicates a quantitative difference in androgen requirements for the male sexual development of the external genitalia and the Wolffian ducts.
