What is Estrogen?

Estrogen is one of the key sex hormones that is essential for sexual and reproductive development. It is primarily responsible for the development of what we consider "feminine" characteristics.

Some key points about estrogen:

• Estrogen is produced mainly by the ovaries. Small amounts are also produced by other tissues like fat cells and the adrenal gland.
• There are three major forms of estrogen in women - estradiol, estriol, and estrone. Estradiol is the predominant and most potent one.
• Estrogen performs a wide variety of functions in the female body:
  • It is responsible for the development of the uterus, vagina, fallopian tubes, and other parts of the female reproductive system.
  • It contributes to the development of secondary sex characteristics during puberty - breast growth, pubic and underarm hair, etc.
  • It regulates the menstrual cycle and prepares the body for pregnancy.
  • It maintains bone strength and density.
  • It influences the production of FSH and LH, which stimulate ovulation.
  • It affects the production of cervical mucus and plays a role in fertility.
• Estrogen levels peak during the fertile window in the menstrual cycle just before ovulation. This triggers the release of an egg from the ovaries.
• After menopause, estrogen levels decline as ovarian function diminishes. This can lead to symptoms like hot flashes, vaginal dryness, mood changes, and bone loss.
• Hormone replacement therapy can provide estrogen to counteract menopausal symptoms. Birth control pills also contain estrogen.
• High estrogen levels may increase the risk for hormonal cancers like breast cancer or endometrial cancer. Lifestyle changes like regular exercise, maintaining a healthy weight, and limiting alcohol intake help keep estrogen in balance.
