Basal serum prolactin values and responses to the administration of thyrotrophin releasing hormone (TRH) in women with amenorrhoea.
Basal prolactin concentrations were measured in 77 patients presenting with amenorrhoea; 17 per cent were found to have hyperprolactinaemia. The release of prolactin in response to a standard dose of thyrotrophin releasing hormone for amenorrhoeic subjects with normal basal levels of prolactin was within the normal range. However, patients with hyperprolactinaemic amenorrhoea and no evidence of pituitary tumour were found to have a blunted response.
