[The coincidence of gonadal dysgenesis and hyperprolactinemia]

It was reported about 6 female patients aged from 3 to 31 years (average age 18 years) with gonadal dysgenesis and hyperprolactinemia. Beside one all these females were not treated with synthetic sexual steroids. In 5 of the 6 patients both hyperprolactinemic and hypergonadotropic serum levels were observed. In one case the gonadotropic serum levels were normal. In 4 patients a stimulation test with GRH-TRH or Arg-GRH-TRH, respectively, was performed. In patients with gonadal dysgenesis a change on the area of the hypothalamic-hypophyseal axis is supposed to cause the hyperprolactinemia.
