[Hyperprolactinaemic endocrinopathy in gynaecological practice (author's transl)].

Prolactin and, to some extent, the gonadotrophins were determined in the serum of 50 patients with amenorrhoea (oligomenorrhoea) and or galactorrhoea. -- Hyperprolactinaemia was safely recorded from 32 cases. That relatively high number of patients with hyperprolactinaemia was attributed to retrograde examination of sterility patients who had been resistant to therapy. -- In the presence of galactorrhoea prolactin levels were increased in nine of 16 patients, whereas the same levels were increased in only three of 18 patients with postpill amenorrhoea. -- Gonadotrophin levels usually dropped in concomitance with marked hyperprolactinaemia, but they failed to deviate from normal with moderate prolactin increase. -- The above results are likely to underscore the importance of prolactin to the diagnosis of gynaecological endocrinopathies.
