Progesterone is the hormone secreted by the ovaries after a woman produces an egg during the middle of her menstrual cycle. Progesterone is the dominant female hormone for the last half of the menstrual cycle.
Female hormonal balance between the estrogen hormones and progesterone is essential in order for women to obtain and maintain health and wellness. The three human estrogen hormones have numerous effects on the body which require the balance of progesterone to prevent the hyper effects of estrogen dominance which can lead to a host of health problems. (See What are the Benefits of Progesterone?) Good health occurs when the hormones in the body are produced in adequate amounts and are in balance. Think of this as hormonal harmony, as if the hormones are a symphony orchestra. If one section of the orchestra, say the brass section, is too loud, then this will drown out the other sections of the orchestra and ruin the symphony.
