Estradiol is a very important hormone in both men and women. It is a sex hormone and is also called E2 or 17β-estradiol. Estradiol is the most potent and predominant form of estrogen found in the human body.
Estradiol has many vital functions, including:
- Development and regulation of the female reproductive system - it is essential for the growth and maturation of the ovaries, uterus, and vagina during puberty. It also controls the menstrual cycle, prepares the body for pregnancy, and maintains pregnancy.
- Development of female secondary sex characteristics during puberty - estradiol stimulates breast growth, widens the pelvis, and causes fat deposition around the hips and thighs giving the female body its curves.
- Bone maintenance - estradiol helps regulate bone formation and maintenance of bone mineral density in both sexes. Deficiency can lead to osteoporosis.
- Role in the central nervous system - estradiol has neuroprotective and anti-inflammatory effects on the brain and influences cognition and mood regulation.
- Cardiovascular effects - estradiol has a beneficial role in maintaining healthy cholesterol levels when balanced with progesterone. It also helps dilate blood vessels.
- Skin and hair health - estradiol improves skin thickness, moisture and Collagen content, reducing wrinkles. It also prolongs the growing phase of hair.
In males, estradiol is produced as a byproduct of testosterone conversion. It is present at lower levels and has essential functions like bone maturation during puberty. Imbalances in estradiol can affect sperm production and libido in men.
The normal range of estradiol is:
- Females:
- Follicular phase: 25-75 pg/mL
- Mid-cycle peak: 85-400 pg/mL
- Luteal phase: 43-211 pg/mL
- Postmenopausal: <15 pg/mL
- Males: 10-50 pg/mL
Estradiol levels are measured through a simple blood test. Imbalances can occur due to many reasons like hormonal disturbances, tumors, menopause, or intake of certain medications.
