title: [Effect of testosterone preparations on the function of the hypothalamic pituitary axis in Klinefelter's syndrome].
abstract: This article prospectively observed the suppressive effects of the testosterone preparations on the elevated gonadotropin levels in Klinefelter's syndrome (KS). After sublingual administration of methyl testosterone 5 mg Bid, the serum T levels increased 97 and 126 ng/ml respectively in 6 normal men and 9 patients of KS and the serum FSH and LH levels did not changed significantly. After intramuscular injection of testosterone propionate 25 mg 3/week testovirone 100 mg 1/10 days and testosterone enanthate 200 mg/20 days, the serum T levels increased significantly both in 6 normal mon and 17 patients with KS. It took about 1 month for the LH levels to decrease to normal range and 3-6 months for the FSH levels to become normal. Our result indicates that it is necessary to treat the KS patients for long period to normalize the increased hypothalamic pituitary function.
