Role of hormone therapy in the management of menopause

Abstract:
There are many options available to address the quality of life and health concerns of menopausal women. The principal indication for hormone therapy (HT) is the treatment of vasomotor symptoms, and benefits generally outweigh risks for healthy women with bothersome symptoms who elect HT at the time of menopause. Although HT increases the risk of coronary heart disease, recent analyses confirm that this increased risk occurs principally in older women and those a number of years beyond menopause. These findings do not support a role for HT in the prevention of heart disease but provide reassurance regarding the safety of use for hot flushes and night sweats in otherwise healthy women at the menopausal transition. An increased risk of breast cancer with extended use is another reason short-term treatment is advised. Hormone therapy prevents and treats osteoporosis but is rarely used solely for this indication. If only vaginal symptoms are present, low-dose local estrogen therapy is preferred. Contraindications to HT use include breast or endometrial cancer, cardiovascular disease, thromboembolic disorders, and active liver disease. Alternatives to HT should be advised for women with or at increased risk for these disorders. The lowest effective estrogen dose should be provided for the shortest duration necessary because risks increase with increasing age, time since menopause, and duration of use. Women must be informed of the potential benefits and risks of all therapeutic options, and care should be individualized, based on a woman's medical history, needs, and preferences.

Hormonal Regulation of the Menstrual Cycle
At puberty, GnRH begins a pulsatile release pattern, which triggers the anterior pituitary gland to secrete follicle-stimulating hormone (FSH) and luteinizing hormone (LH). The frequency and amplitude of GnRH pulses vary across the menstrual cycle, with faster pulses favoring LH release and slower pulses favoring FSH release.
Major Hormones and Their Functions
Oxytocin, produced in the hypothalamus and released by the pituitary gland, plays a role in social bonding, childbirth, and lactation.
Hormonal Control of the Ovarian Cycle
Before puberty, the hypothalamus releases GnRH in a low frequency, low amplitude pulsatile manner. This along with the immature hypothalamic-pituitary-gonadal axis activity, results in low estrogen levels and the absence of a fully functional ovarian cycle. At puberty, GnRH secretion increases in both frequency and...
