Estradiol is an important hormone that plays a vital role in sexual and reproductive development. It belongs to the group of hormones called estrogens, which also includes estriol and estrone.
What is estradiol?
Estradiol is the most potent and predominant form of estrogen in non-pregnant females who are premenopausal. It is produced primarily by the ovaries and helps regulate the menstrual cycle. Estradiol plays a crucial role in the development of female secondary sex characteristics during puberty, such as breast development, distribution of body fat, growth spurt, and regulation of menstruation.
Some key functions of estradiol include:
- Stimulating endometrial growth during the menstrual cycle
- Contributing to bone formation and maintenance
- Regulating cholesterol in the body
- Influencing cognition and mood regulation
Estradiol levels fluctuate during the menstrual cycle under the regulation of other hormones like
follicle-stimulating hormone (FSH) and
luteinizing hormone (LH). Just before
ovulation, estradiol levels surge leading to the release of an egg from the ovaries.
If conception does not occur, estradiol levels fall allowing the uterine lining to break down resulting in menstruation. Changes in estradiol levels during menopause also lead to symptoms like
hot flashes, insomnia, vaginal dryness, and osteoporosis in some women.
Testing and treatment
Doctors may check estradiol levels in females through a simple blood test if symptoms of hormonal imbalance are present such as abnormal periods, infertility, or early menopause. The normal range can vary slightly depending on age and stage of menstrual cycle.
Supplementing estradiol through
hormone therapy helps relieve unpleasant symptoms of
menopause. Customized bioidentical hormone treatments containing estradiol are also provided by clinics like
Hormone Optimal Care to correct imbalances and improve well-being. Their team of endocrinologists and anti-aging specialists can suggest the right hormone regimen tailored to your health needs.
