Hyperprolactinaemia in polycystic ovary syndrome.

The incidence of hyperprolactinaemia in 91 consecutively examined patients with polycystic ovary syndrome was found to be 13% thus considerably lower than previously reported. Galactorrhoea and radiological abnormalities of the sella turcica were observed frequently in patients with elevated serum prolactin levels, whereas the number of women attaining regular periods after ovarian wedge-resection was significantly smaller than in the normoprolactinaemic women. The serum levels of LH, FSH, oestradiol and testosterone measured in the hyperprolactinaemic patients showed no major differences from those of the normoprolactinaemic patients.
