Progesterone, primarily a female hormone but also found in males in small amounts, is made in the ovaries, the adrenal glands, and in the placenta during pregnancy. It is one of the major regulatory hormones. Like estrogen, progesterone levels decline with age. Female progesterone levels drop drastically at menopause. Progesterone helps estrogen levels remain within a therapeutic range and therefore, can protect against endometrial cancer of the uterus.

When dealing with female sex hormones, the balance amongst them often is more important than the actual levels. This is true of the ratio of estrogen to progesterone, as well as estrogen to testosterone. In females, a higher ratio of testosterone to estrogen is indicative of an increased risk of heart disease (the opposite is true in males). In females, as the progesterone to estrogen ratio decreases, it creates estrogen dominance and subsequently an increased risk of breast cancer. Estrogen and progesterone act in tandem to control cell growth for normal function.

Bio-identical estrogens have the same molecular structure as the estrogens found in the human female. These natural plant estrogens are altered so that they have the same bio-identical structure as the estrogens found in human females. Unlike many FDA- approved estrogen medications, natural bio-identical soy-derived estrogens are safe, effective.

Combining the benefits of bio-identical estrogen and progesterone replacement provide many of the benefits without the risks. Together they can improve or prevent osteoporosis, improve mood and mental status, improve sexual function or libido.
