T von Holst,

The endocrinology of the perimenopause--the time between pre- and postmenopause--is characterized by changes in the metabolism of the steroid hormones caused by increasing insufficiency of the ovaries. Until the age of 48 the concentrations of the estrogens are relatively constant with a median level of 120 pg/ml serum for estradiol and of 75 pg/ml for estrone. Between the age of 49 and 54 the levels decrease to concentrations of 35 pg/ml for estrone and 10 pg/ml for estradiol. In the corresponding time, there is a tenfold rise of the level of FSH. The level remains constant until high age. The decrease of the estrogens causes the menopause in an age of 51 to 52. In the postmenopause the ovaries don't play a role for the concentrations of the estrogens. The concentrations are determined by the conversion of the androgens secreted by the adrenal cortex. The serum concentrations of androstenedione are five times higher than those of testosterone. The function of the adrenal cortex remains until high age; there is no 'adrenopause' comparable to the 'menopause'. The suppression of the adrenal cortex by treatment with corticoids (e.g. for asthma) causes a dramatic decrease of the androgens and consecutively for the estrogens. The lack of estrogens play an important role in the induction of osteoporosis and other disturbances of the late postmenopause, e.g. coronary heart disease. Obese women show in the pre- and the perimenopause more often dysfunctional bleedings caused by anovulation or corpus luteum insufficiency.(ABSTRACT TRUNCATED AT 250 WORDS)
