Estrogen is one of the key sex hormones that plays an integral role in female physical development and reproduction. It is responsible for development of secondary sexual characteristics in girls during puberty, regulating the menstrual cycle, and supporting pregnancy.
What does estrogen do?
Some of the major functions of estrogen in the female body include:
- Development of female reproductive organs and breasts during puberty
- Regulation of the menstrual cycle
- Thickening the lining of the uterus to prepare for implantation of a fertilized egg
- Maintaining the uterine lining during early pregnancy
- Regulating bone density and strength
- Influencing release of other hormones like progesterone
Types of Estrogen
The three major types of naturally occurring estrogens in women are:
- Estrone - produced mainly after menopause
- Estradiol - the predominant estrogen during reproductive years
- Estriol - the main estrogen produced during pregnancy
Estrogen Production
In premenopausal women, estrogen is predominantly produced by the
ovaries. Some quantity is also produced in fat tissues and the adrenal glands.
During the menstrual cycle,
estradiol levels usually peak just before
ovulation. This triggers release of an egg from the ovaries.
If pregnancy occurs, high levels of
estriol are produced by the placenta to support fetal growth and development.
After menopause, estrogen levels significantly drop but some estrone continues to be produced in fat tissues. Many women may experience symptoms like hot flashes and vaginal dryness due to this natural
decline in estrogen.
