Estradiol is one of the main estrogens or sex steroid hormones produced by the ovaries. Simply put, estradiol is an important hormone that regulates ovulation and aids in the development of secondary sex characteristics in women.
Some key points about estradiol:
- Estradiol helps control a woman's menstrual cycle. It thickens the lining of the uterus during the follicular phase, enabling fertilization and implantation of the embryo if pregnancy occurs.
- Optimal levels of estradiol aid in producing cervical mucus that helps sperm travel through the cervix. This facilitates fertilization.
- Estradiol regulates breast development in puberty and plays a role in bone maintenance. It contributes to bone mineral density and protection against osteoporosis.
- Along with other hormones, estradiol influences mood, cognition, and overall well-being in women.
- During perimenopause and menopause, estrogen levels, including estradiol, start to decline. This contributes to menopausal symptoms like hot flashes, night sweats, vaginal dryness, etc.
