striol (E3), also spelled oestriol, is a steroid, a weak estrogen, and a minor female sex hormone. It is one of three major endogenous estrogens, the others being estradiol and estrone. Levels of estriol in women who are not pregnant are almost undetectable. However, during pregnancy, estriol is synthesized in very high quantities by the placenta and is the most produced estrogen in the body by far, although circulating levels of estriol are similar to those of other estrogens due to a relatively high rate of metabolism and excretion.Relative to estradiol, both estriol and estrone have far weaker activity as estrogens.
In addition to its role as a natural hormone, estriol is used as a medication, for instance in menopausal hormone therapy; for information on estriol as a medication, see the estriol (medication) article.
Injections of estradiol are sometimes given to treat symptoms like these. They can also be used to compensate for ovary failure or similar conditions in women, and some forms of it can treat symptoms caused by prostate cancer in men. When given to women, it is necessary for them to use an effective form of birth control, due to the high risk of complications and birth defects that would exist in the event of a pregnancy.
Despite a common belief to the contrary, estrogens are important for male reproductive health and development as well. Estradiol is produced by a certain type of cell in the testes, and evidence suggests that it may be responsible for preventing the spontaneous death of sperm cells. Elevated levels can have negative effects, including a lowered sperm count. Males who have genetic conditions involving the sex chromosomes, such as Klinefelter's Syndrome, often have higher-than-normal levels. While it is primarily a sex hormone, estradiol also has complex interactions with the liver, governing the production of certain proteins, including those responsible for blood clotting.
