What is Estradiol?
Estradiol is the most potent, naturally occurring estrogen in the human body. It is a sex hormone that is essential for sexual and reproductive development, mainly in women.
Some key facts about estradiol:
- Estradiol plays a vital role in regulating the menstrual cycle. It controls the growth and shedding of the endometrium (uterine lining) during the menstrual cycle to prepare the body for pregnancy.
- It is produced mainly by the ovaries and small amounts are also made in other tissues like fat. Estradiol production peaks right before ovulation.
- In addition to reproduction, estradiol is important for bone health, cardiovascular function, brain function, skin health, and more in both males and females.
- Levels of estradiol fluctuate during the menstrual cycle and are highest just before ovulation. After menopause, estradiol levels decline as ovarian function diminishes.
- Estradiol works by binding to estrogen receptors on cells throughout the body. This triggers gene expression and physiological responses in those tissues.
- Abnormal estradiol levels can cause issues like irregular periods, infertility, osteoporosis, and metabolic problems. Hormone replacement therapy can help normalize levels.
- Estradiol levels can be tested with a simple blood test. Tracking levels over time gives insight into ovarian function and menopause transition.
In summary, estradiol is an essential sex hormone that coordinates reproduction and impacts systems all throughout the body. Getting estradiol levels tested and addressing abnormalities is important for wellbeing. While mainly considered a female sex hormone, estradiol also plays biological roles in men.
