The value or plasma radio-immune assays of steroid and pituitary hormones in amenorrhoea is discussed. The accent is placed on the need for repeated plasma sampling. Dynamic tests aimed at investigating the hypothalamo-hypophysial-ovarian axes are analysed. A proposal is put forward for a scheme of investigation that will make better use of these tests.
