Estradiol is the most potent and predominant form of estrogen in the human body. It is a steroid hormone produced primarily by the ovaries and placenta during the reproductive years of cisgender women and smaller amounts are also produced by the adrenal glands and testes in people of all genders.
What are some key functions of estradiol?
Estradiol plays a vital role in numerous processes in the body for people of all genders. Some of its main functions include:
- Regulating the menstrual cycle and supporting reproduction in cisgender women
- Contributing to bone strength and density
- Impacting salt and water balances in the body
- Influencing cholesterol levels and cardiovascular health
- Affecting skin health and quality
- Potentially supporting brain, memory and mood regulation
Estradiol levels fluctuate naturally during the menstrual cycle and with age. When estradiol is out of ideal range, people may experience symptoms like hot flashes, night sweats, vaginal dryness, headache, mood changes, sleep disruptions, and more.
If you are experiencing perimenopausal or menopausal symptoms related to shifting estrogen levels, consider contacting Renew Hormone Clinic to explore customized bioidentical hormone therapy options to help you find balance and relief. Our caring team of hormone specialists can provide safe, effective treatment plans with estradiol and other hormones tailored to your unique needs and goals.
What causes low or high estradiol?
Imbalances in estradiol can stem from various factors. Common causes of low estradiol include:
- Perimenopause and menopause
- Ovarian failure or ovary removal surgery
- Excessive exercise or low body weight
- Certain medications, chemotherapy or radiation
High estradiol can sometimes result from:
- Estrogen-producing tumors
- Pregnancy
- High-dose external estrogen intake
- Certain health conditions like polycystic ovarian syndrome (PCOS)
How is estradiol measured and monitored?
Doctors can measure estradiol levels through a simple blood test. Estradiol blood tests are often done:
- To investigate menstrual cycle or menopausal symptoms
- To monitor hormone therapy
- To assess ovarian function and reserve
- To diagnose conditions like PCOS or tumors
- To support fertility treatments
Keeping your estradiol in a healthy range is important for overall wellbeing. Work with your healthcare provider to track your hormone levels and address any imbalances with lifestyle changes, medications, or hormone therapy as needed.
