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. It is important for both men and women to have optimal levels of oestradiol as it is essential for bone strength, libido and sexual function, and the distribution of fat. 

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

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.

Oestradiol blood test results below 18.4 pmol/L are expressed as <18.4 pmol/L (less than 18.4 pmol/L) due to the sensitivity of the testing assay.
