Estrogen is a group of hormones that play an essential role in the growth and development of female sexual characteristics and the reproductive system. The three major naturally occurring estrogens in women are:
- Estrone
- Estradiol
- Estriol
What does estrogen do?
Estrogen performs a wide variety of functions in the female body including:
- Development of female sexual characteristics during puberty such as breasts, widening of hips, menstrual cycles etc.
- Regulates the menstrual cycle
- Maintains the lining of the uterus during the menstrual cycle
- Plays a role in pregnancy by supporting fetal development
- Affects the release of eggs from the ovaries (ovulation)
- Helps maintain bone strength and health
- Influences skin health and appearance
- Impacts heart health and cholesterol levels
Where is estrogen produced?
The main sources of estrogen production are:
- Ovaries - Produce estrogen to trigger ovulation and menstruation
- Adrenal glands - Produce small amounts of estrogen
- Fat cells - Aromatase enzymes convert androgens into estrogen
- Placenta - Large amounts of estrogens produced during pregnancy
Estrogen levels across a woman's lifespan
Estrogen levels vary significantly at different life stages:
- Puberty - Rising estrogen triggers development of female sexual characteristics
- Reproductive years - Estrogen levels peak during the reproductive years
- Menopause - Estrogen levels rapidly decline during perimenopause and menopause
- Post-menopause - Low levels of estrogen post-menopause increase risks of osteoporosis, heart disease etc.
Supplementation
During perimenopause and post-menopause, some women may need to take low-dose estrogen therapy to help manage menopausal symptoms. However, the risks and benefits of hormone therapy should be carefully considered. Lifestyle changes like regular exercise, healthy diet, and stress management can also help manage declining estrogen levels.
In summary, estrogen is an essential female hormone that plays a vital role in sexual development, the reproductive cycle, and maintenance of bone, heart, and overall health. Changes in estrogen levels at different life stages lead to associated effects and risks that women should be aware of.
