Importance of estrogen for women
Estrogens are the most important hormones that influence the lives of women. Estrogens are the hormones responsible for female sexual characteristics such as breast development and menstrual cycle. For young women, puberty begins when estrogen production increases in the eggs. Estrogen level remains relatively unchanged for 25 years, after which decrease steadily. The body tries to fight this problem by producing two other pituitary hormones: the egg stimulating hormone (FSH) and Luetinisante Hormone (LH). However, decreased levels of estrogen and increased production of FSH and LH create symptoms such as hot flashes or night sweats. There are three main forms of estrogen found in the human body: estrone, estradiol and estriol. Estradiol is the most commonly measured type of estrogen to nonpregnant women. The amount of estradiol in the blood varies throughout the menstrual cycle. After menopause , estradiol production falls to a very low but steady. In men, FSH and LH are necessary for the formation of sperm and stimulating the synthesis of testosterone. So no surprise that men sometimes show the same symptoms as women.

Indeed, they operate at all levels: cardiac , neuro-psychological, temperature control … Hence the presence of clinical signs varied when the thyroid gland malfunction.
The pituitary is the “head” of the glands of the body and therefore of the thyroid. It is a small gland at the base of the brain and it secretes hormones, including TSH (Thyroid stimulating hormone) which regulates the secretion of T3 and T4. If they fall, the pituitary then secretes more TSH to try to increase their concentration. Read the rest of this entry »
