[Growth hormone and prolactin levels in galactorrhea of unknown etiology]

We tested the levels of prolactin and growth hormone in the group of 50 patients with galactorrhoea of unknown etiology during the investigation that took one year. The control group consisted of 21 patients. All of the 71 patients were in fertile ages (20-40 years), healthy, not being pregnant in last six months, not breast-feeding, not being under medication, and did not experience total anesthesia in last three months. Hormone levels were estimated through usual procedure, on the 10th and 22nd day of menstrual cycle. According to the menstrual cycle, the patients were divided into three groups: with regular cycle, with irregular cycle and with amenorrhea. We found that the patients with galactorrhoea of unknown etiology did not have elevated levels of prolactin hormone. As for growth hormone, we found that in patients with regular and irregular cycles it had been elevated in the second phase of the cycle (statistical significance of differences on 0.05 level), while in patients with amenorrhea the growth hormone was significantly increased (statistical significance of differences on 0.01 level).
