Climacteric disorders and menopause are concerned by female patients.After menopause,women can be treated by hormone replacement therapy.Estrogen
is the key hormone to ease the difficulty of aged women.Estrogen and progesteron are controled by the hypothalamus-pituitary gland system of the brain.
The level of the female hormone is maintained by the hormonal feedback system.FSH(follicle stimulating hormone) stimulates the estrogen secretion from the ovary and LH(luteinizing hormone) stimulates the progesteron secretion from the ovary.
