Estrogen and Progesterone

Meaning

Estrogen and Progesterone are the two primary female sex steroid hormones, though they are present and physiologically important in all genders. Estrogen is a collective term for estradiol, estrone, and estriol, primarily responsible for the development of female secondary sexual characteristics and maintaining reproductive, bone, and cardiovascular health. Progesterone is crucial for the menstrual cycle, pregnancy, and exerts significant neuroprotective and calming effects in the central nervous system. The precise ratio and rhythm of these hormones are fundamental to hormonal balance and overall vitality.
