Estradiol, often shortened to E2, is the most potent naturally occurring estrogen in women. A steroid hormone, it plays a key role in the female reproductive system and influences various other bodily functions in both men and women.
What does estradiol do?
Estradiol's functions are multifaceted:
Where does estradiol come from?
In women, the ovaries are the primary source of estradiol. During pregnancy, the placenta also produces significant amounts. In men, smaller amounts are produced by the testes and adrenal glands.
What happens when estradiol levels are off?
Low estradiol (hypoestrogenism) can cause irregular periods, infertility, vaginal dryness, decreased libido, mood swings, sleep problems, and increased risk of osteoporosis. This is especially prevalent during and after menopause. High estradiol (hyperestrogenism), less common without hormonal treatments, can manifest with symptoms such as weight gain, irregular periods, mood swings, blood clots, and breast tenderness.
How are estradiol levels measured?
A blood test can measure estradiol levels. Your doctor may order this test if they suspect low or high levels based on your health concerns. It's also commonly used to monitor fertility treatments or hormone replacement therapies.
Is estradiol synthetically produced?
Yes. Synthetic estradiol is used in hormone replacement therapy (HRT) to manage symptoms of menopause, post-menopause, hormone imbalances, or conditions following breast surgery. These medications require a prescription from a physician. Self-medicating is dangerous and should be avoided.
In a nutshell, estradiol is a vital hormone with wide-ranging effects. Understanding its role is crucial for overall health and well-being. Consult your doctor if you have concerns about your estradiol levels.
