Maintaining estrogen balance can be difficult for many. For many decades of a woman’s life circulating estrogens are fluctuating and cause both good and bad influences. The primary role of estrogen is to maintain the growth and function of the uterus so that the sex organs can become adult sized, and prepares the uterine lining to accept an egg. Additionally, estrogen affects skeletal growth, skin, fat and protein deposition, and electrolyte balance. Men also produce a certain amount of estrogen.
Progesterone is the building block for many other major hormones. Other sex hormones are formed from progesterone, including the corticosteroids, which are essential for stress response, electrolyte balance, blood pressure, and lastly, survival. Progesterone is the primary hormone of fertility and pregnancy. It is essential to the survival of the fertilized egg, then the embryo, then the fetus. In pregnancy, it prevents the shedding of the uterine lining. A drop in progesterone can result in a miscarriage.
