Estradiol is one of the most important sex hormones in women. It plays a vital role in the development and regulation of the female reproductive system and secondary sex characteristics. But what exactly is estradiol and how does it affect the body?
Estradiol is a form of estrogen, the primary female sex hormone. It is produced mainly by the ovaries and also in smaller amounts by the adrenal glands and fat tissue. Estradiol levels fluctuate throughout a woman's menstrual cycle, peaking just before ovulation and dropping during menstruation.
What does estradiol do?
Estradiol has numerous critical functions in the female body:
- Stimulates breast development during puberty and maintains breast tissue in adulthood
- Regulates the menstrual cycle by controlling the growth of the uterine lining
- Plays a role in bone maintenance helping prevent osteoporosis in older age
- Affects female distribution of fat tissue
- Influences reproductive health and fertility
- May impact sexual desire and arousal
Estradiol also has effects on other body systems like the cardiovascular system and even the brain.
Some research indicates it may help with neuronal growth and memory.
What are normal estradiol levels?
Estradiol levels vary widely depending on a woman's age and where she is in her menstrual cycle. In general, prepubertal girls have very low levels less than 20 pg/mL. During the reproductive years, a normal estradiol range is:
- Follicular phase: 25-75 pg/mL
- Mid-cycle peak: 85-400 pg/mL
- Luteal phase: 43-250 pg/mL
- Postmenopause: less than 10 pg/mL
Imbalances in estradiol, either too high or too low, can lead to unpleasant symptoms and health effects. Some include hot flashes, menstrual irregularities, vaginal dryness, insomnia, headache, mood changes, and more.
