What is the function of oestradiol?

Oestradiol, which is also known as E2, estradiol and 17-beta (o)estradiol, is a reproductive hormone in men and women, although, men do not need as much oestradiol as women.

For women, oestradiol mainly acts to mature and maintain the female reproductive system, with Oestradiol being the strongest of three naturally produced oestrogens. Oestradiol plays a role in:

  • The development and subsequent release of an egg during ovulation
  • The preparation of the uterus in the event of fertilisation
  • Promoting the development of breast tissue
  • Enhancing bone and cartilage density

As women age, Oestradiol levels slowly reduce. During the menopause, there is a large decrease in the levels of Oestradiol when the ovaries switch off. This is associated with menopausal symptoms such as hot flushes, night sweats, vaginal dryness, mood swings, depression, and fatigue. After the menopause, women are at an increased risk of osteoporosis because of a lack of estrogen. If you have an excess of Oestradiol, you may experience a variety of symptoms from acne, low sex drive, constipation, depression and weight gain to infertility, stroke, heart attack and an increased risk of developing breast and uterine cancer.

For men, Oestradiol contributes to sperm production, resulting from the conversion of testosterone within the testes. In men, an excess of Oestradiol can result in sexual dysfunction, loss of muscle tone, increased body fat, and the development of female characteristics, such as breast tissue.
