Gonadotropin secretion and hypothyroidism.
Hypothyroidism is generally associated with hypogonadotropism. Occasionally, however, increased gonadotropin concentrations are encountered. The mechanisms, presumably hypothalamic, which determine the gonadotropin shift are unclear. A case report of hyperprolactinemic hypothyroidism with associated hypergonadotropism is presented. The previous literature is reviewed. It appears that hypothyroidism is generally associated with a decrease in the gonadogropin secretion. However, hypothyroidism with exxagerated hTSH secretin and hyperprolactinemia can be associated with increased gonadotropin secretion.
