[Role of prolactin determination in sterility diagnosis (author's transl)]

Prolactin, luteinising hormone, follicle-stimulating hormone, 17beta-oestradiol, and testosterone were measured from sera of 307 sterility patients with anovulatory cycles or amenorrhea, among them 32 women with galactorrhoea. Hyperprolactinaemia, with values being between 720 mU and 38.000 mU of prolactin/L, was recorded from 34 patients (11.1 per cent). Increased prolactin levels were recordable from 14 patients with galactorrhoea (43.8 per cent). Gonadotrophins in patients with hyperprolactinaemia were normal in 15 cases and drastically reduced in 19. Strongly reduced 17beta-oestradiol values were measured, at the same time, in eight cases. The above results were matched against literature data.
