Estrogen is one of the most important hormones in the female body. It is responsible for the development and regulation of the female reproductive system and secondary sex characteristics. There are three major types of estrogen - estradiol, estriol, and estrone.
Estradiol is the primary estrogen during a woman's reproductive years. It is produced mainly by the ovaries and promotes the growth of the uterine lining during the first part of the menstrual cycle. Estradiol levels drop during menopause, causing many of the symptoms associated with it.
Estriol is the main estrogen produced during pregnancy. It is made by the placenta and helps support fetal growth and development. High levels of estriol help prepare the body for childbirth.
Estrone is a weaker estrogen that is produced by body tissues like fat. After menopause, estrone is the predominant estrogen in a woman's body. It helps maintain bone density and skin elasticity.
Some key facts about estrogen:
- Stimulates breast growth at puberty and regulates breast size in adulthood
- Contributes to feminine fat distribution around the hips, thighs, and buttocks
- Maintains the lining of the vagina and uterus by controlling cell growth
- Plays a role in regulating the menstrual cycle and ovulation
- Helps build and maintain bone density
Estrogen also has effects throughout the body:
- Improves cholesterol levels by increasing HDL ("good" cholesterol) and decreasing LDL ("bad" cholesterol)
- Helps regulate body temperature
- Influences production of clotting factors
- May offer some protection against heart disease and osteoporosis in women
Estrogen levels naturally fluctuate throughout a woman's life during puberty, menstruation, pregnancy, and menopause. Taking medications like birth control pills or receiving
hormone therapy can also affect estrogen levels.
Some women may experience low estrogen levels due to primary ovarian insufficiency, eating disorders, excessive exercise, or surgical removal of the ovaries. This can lead to symptoms like hot flashes, vaginal dryness, and mood changes. Hormone replacement therapy may be recommended in these cases.
