Begin tampering with nature's finely tuned messengers of life's processes and you are asking for trouble. A woman's physiology and psyche are intimately connected to her monthly flow of hormones.
Hormones stimulate, regulate and control all vital bodily functions.
The two main sex hormones in a woman's body are estrogen and progesterone. Estrogen actually refers to a class of hormones. The key estrogens are estradiol, estrone and estriol . These estrogens are produced mainly in the ovaries although small quantities are secreted from the adrenal glands, the placenta during pregnancy and in fat cells. However, progesterone is both the name of the class and the single member of the class.
