Nineteen cases of sexual disturbance caused by endocrine dysfunction were surveyed for the clinical features. In hypogonadotropic hypogonadism ejaculatory failure was observed in 12 out of 13 cases. On the contrary, 2 of three hypergonadotropic patients preserved their ejaculation. The serum testosterone levels of hypogonadotropic and hypergonadotropic hypogonadisms were less than 200ng/dl. When the testosterone level decreased to less than 100ng/dl, nine patients out of 13 complained loss of libido and 12 patients complained loss of ejaculation, but six patients preserved erectile function.
Hyperprolactinemic patients showed loss of libido in 4, erectile failure in 4 and loss of ejaculation in 2.
When good response to hCG test was present or the testicular volume was more than 4ml, patients with hypogonadotropic hypogonadism showed good response to hCG therapy.
