Oestradiol is a female steroid hormone, produced in the ovaries of women and to a much lesser extent in the testes of men. It is the strongest of three oestrogens and is responsible for the female reproductive system as well as the growth of breast tissue and bone thickness. In pre-menopausal women, oestradiol levels vary throughout the monthly cycle, peaking at ovulation. In women, oestradiol levels decline with age, culminating with the menopause when the ovaries stop producing eggs. Low oestradiol can cause many symptoms associated with the menopause, including hot flushes, night sweats and mood swings. Low oestradiol can also cause osteoporosis.
Special instructions

How to prepare for your test

Prepare for your Oestradiol Blood Test by following these instructions. Take this test two to five days after the start of your period, ideally on day three. It can be taken any time if you do not have periods. Avoid taking a finger-prick sample from a finger used to apply hormone gels/pessaries/patches in the past 4 weeks. Use gloves to apply these. Do not take biotin supplements for two days before this test, discuss this with your doctor if it is prescribed. Hormonal contraception can affect the results of this test. Taking a break from this and waiting for your periods to restart before your blood test will give more accurate results.

Why is oestradiol important for women?

In women, oestradiol is secreted by the ovaries, adrenal glands and placenta during pregnancy. It is responsible for developing and maintaining reproductive structures, including fat distribution, preparing the follicle in the ovary for the release of an egg, and helping maintain bone density.

Why is oestradiol important for men?

In men, oestradiol is converted from testosterone by the action of the aromatase enzyme. Elevated oestradiol in men can cause gynaecomastia, also known as moobs or man-boobs.

What is oestradiol?

Oestradiol is a steroid hormone that accounts for 80% of the oestrogen in the female body. It is also found in men at much lower levels. Both men and women need to have optimal levels of oestradiol as it is essential for bone strength, libido and sexual function, and fat distribution.
