Estradiol also known as Estrogen (for men)

17-bêta-oestradiol Estradiol (17-ß-) (E2) from serum.

Estradiol concentrations are low in men. About 30% is produced by the testes and the rest comes from conversion in the liver and adipose tissue.

Estradiol not only affects the reproductive system, but also influences bone structure, among other things.

Estrogen is as important to men as testosterone.

Estrogen levels in the elderly can be high because of obesity and particularly because of fat mass.

It is assumed that almost everything that makes men men depends on testosterone. And that the "female" hormone estrogen has nothing to do with it. Recent research has remarkable news. In men, much depends on the amount of female hormone, including their sex drive and weight. Even though testosterone levels are rising. It has recently become clear that the role of the female hormone is much more decisive than was thought. A reduction in estrogen levels also seems to be a major cause of men gaining fat around the waist as they age.

Medical reasons for determination of estradiol in blood in men may include:

• Suspicion of high oestradiol levels in men
• In men with breast development
• Checking aftertreatment

Estradiol is bound to sex hormone binding globulin (SHBG). If there is a decreased SHBG value then this will affect the estradiol result. Normal levels of SHBG are assumed when establishing reference values. LH and FSH measurements can support to see what is going on.

The measurement range goes up to >11010 pmol/L
