title: Hormone profiles in Klinefelter's syndrome with and without testicular epidermoid cyst.
abstract: Hormonal studies were performed in patients of Klinefelter's syndrome with and without testicular epidermoid cyst. Mean levels of plasma gonadotropins were elevated above normal ranges. The mean testosterone level in plasma was abnormally low. The mean prolactin level in plasma was within the normal limit. However, mean plasma levels of these hormones were not significantly different between the two groups. The administration of LH-RH resulted in low response of plasma gonadotropins. The response of plasma testosterone to the administration of hCG was also abnormally low. However, in the LH-RH and hCG tests there were no significant differences between the two groups. These data suggested that the hormonal disturbance in Klinefelter's syndrome is unrelated to the occurrence of testicular epidermoid cyst.
