[Use of function tests in the diagnosis of hyperprolactinemia in women treated for sterility].

28 women with hyperprolactinaemia were examined (prolactin levels varied from 720 to 66000mlU/l). These patients were subjected to the functional tests with GnRH, TRH and metoclopramid. In all groups of the patients, who were devided acording Prolactin levels, the sensitivity of lactotrophs was decreased. There is reserve correlation between levels of the prolactin and gonadotrophins (r = -0.64). The test with metoclopromid is more informative in the diagnosis of tumoral and functional hyperprolactinaemia.
