  1. Estrogen and Progesterone Progesterone and estrogen are the two most important hormones in the female body. These are steroid hormones that are responsible for various female characteristics in the body. The ovaries are a pair of ova-producing organs (that is, they produce egg cells) that maintain the health of the female reproductive system. In addition to their role in producing ova, the ovaries also have the distinction of being an endocrine gland because they secrete hormones—primarily estrogen and progesterone—that are vital to normal reproductive development and fertility. Estrogen, a steroid hormone, carries physiological messages to body organs and systems. These messages differ for each body organ and system. Estrogen sends messages to the uterus to grow and replace the lining that is shed during the previous menses. The three major naturally occurring estrogens in women are estrone (E1), estradiol (E2), and estriol (E3). Estradiol is the predominant estrogen during reproductive years both in terms of absolute serum levels as well as in terms of estrogenic activity. During menopause, estrone is the predominant circulating estrogen and during pregnancy estriol is the predominant circulating estrogen in terms of serum levels. Though estriol is the most plentiful of the three estrogens it is also the weakest, whereas estradiol is the strongest with a potency of approximately 80 times that of estriol.
