Postmenopausal Hormone Status describes the characteristic profile of circulating sex steroids and gonadotropins in a woman who has experienced 12 consecutive months of amenorrhea, marking the permanent cessation of ovarian function. This status is defined by significantly low levels of estrogen and progesterone, coupled with markedly elevated levels of the pituitary gonadotropins, Luteinizing Hormone (LH) and Follicle-Stimulating Hormone (FSH). Clinically assessing this status is crucial for evaluating symptoms, determining the need for hormone replacement therapy, and assessing long-term health risks related to estrogen deficiency, such as bone loss and cardiovascular changes.
Origin
This term is a standard clinical descriptor within reproductive endocrinology, signifying the final stage of the reproductive lifespan. The definition is based on the physiological observation of ovarian follicular depletion and the resulting failure of the negative feedback loop to the pituitary. The term ‘status’ emphasizes the stable, albeit altered, hormonal equilibrium achieved after the menopausal transition is complete.
Mechanism
The physiological mechanism is ovarian senescence, where the ovaries no longer respond to FSH and LH stimulation due to the exhaustion of the follicular reserve. This lack of response results in a drastic drop in estrogen and inhibin production. The pituitary, sensing the low sex steroid levels, attempts to stimulate the gonads by dramatically increasing the output of FSH and LH, leading to the characteristic high-gonadotropin, low-sex-steroid profile that defines the postmenopausal status.
