Estradiol is a key female sex hormone that plays many important roles in the body. It is one of the three major estrogens produced by the body, along with estrone and estriol. Estradiol has numerous functions, including:
- Regulating the menstrual cycle - Estradiol is responsible for controlling the menstrual cycle. It stimulates the growth of the uterine lining during the first half of the menstrual cycle. High levels of estradiol trigger ovulation. After ovulation, estradiol levels decrease and this signals the uterus to shed its lining.
- Breast development - Estradiol promotes the growth of breast tissue during puberty and pregnancy. It stimulates ductal growth and cooperates with other hormones like progesterone to cause full breast enlargement.
- Bone maintenance - Estradiol helps regulate bone remodeling and maintain bone density. It prevents excessive bone resorption by osteoclasts. This is why low estradiol after menopause leads to osteoporosis.
- Brain function - Estradiol influences areas of the brain like the hypothalamus, hippocampus, and amygdala. It impacts cognition, memory, mood and more. Declining estradiol during menopause is linked to problems like depression, anxiety, and dementia.
- Heart health - Estradiol has a protective effect on the cardiovascular system. It helps keep blood vessels flexible and dilated, lowering blood pressure. It also helps regulate cholesterol.
- Skin and hair - Estradiol improves skin thickness, hydration, and collagen content. It may also prolong the growing phase of hair follicles and prevent hair thinning.
So in summary, estradiol is the predominant and most potent estrogen in females during reproductive years. It plays pivotal roles in the regulation of the menstrual cycle, reproductive health, bone density, brain function, heart health, and more. Estradiol levels start to rise during puberty and peak during the child-bearing years until menopause causes a dramatic drop in production.
