Estriol is a metabolic product of Estradiol and Estrone created in the urine of pregnant women in high concentrations. It is produced by the fetal liver and in the placenta during pregnancy. It is assumed that production of large amounts of Estriol during pregnancy ensure a quiet uterus along with the majority of the myometrial nuclear receptors, by exiting an insufficient number for a stimulatory estradiol concentration.
The abnormal level of Estriol revel the abnormality in the development of a woman fetus and suggest for more tests and screening. So, doctors suggest the routine quad screen including Estriol test to check out the development. Another assumption about the Estriol is that it amount of formation can be controlled by the amount of estradiol present.
The Estriol's strong point or flaw is totally dependent on the extent of severity and persistent while given to infantile animal. On the other hand, if it is given with the estradiol, it can also serves as an antagonist. The Estriol also play its role in the growth of breast cancer but act as an antagonist to the G-protein coupled estrogen receptor at the same time. It does not usually increase the risk of hormone-dependent cancers of the breast or endometrium among women. The use of Estriol for therapeutically purpose is also confirmed by most of the researchers.
The Estriol is further used in the screening and can be measures in the urine or blood of a woman have pregnancy. It is also used as an indicator of the heath of a pregnant woman as her adrenal cortex produces DHEA-S that is transformed in to Estriol by the help of placenta.
One of the major uses of Estriol is in the screening as it can be easily measured in the urine or blood. So, it acts as an indicator of the fatal health of pregnant women. The fetus of mother creates DHEA-S that is also changed to Estriol by placenta.
The significant lower level of unconjugated Estriol among pregnant women shows the chromosomal or congenital related anomalies such as Down syndrome or Edward's syndrome. It is incorporated as part of the test such as triple test & quadruple test for screening of fetal anomalies. There are many pathological situations presented in a pregnant woman that can basis the deviations in the Estriol levels. Such screenings are frequently seen as less perfect of fetal-placental health as the non-stress testing. The conditions that create false positives and false negatives in the testing of Estriol for fetal misery contain preeclampsia, anemia as well as the impaired kidney function.
In concluding, Estriol, once supposed to be insignificant and weedy, but many protective effects have seen for it against other stronger estrogens. That's why; it is a comparatively safer choice for the bioidentical hormone-replacement therapy.
