關於Estriol微粉化
Estriol Micronized是一種性激素，可用於激素替代療法。 
Estriol (E3), also spelled oestriol, is a steroid, a weak estrogen, and a minor female sex hormone.雌三醇（EXNUMX），也拼寫為雌三醇，是類固醇，弱雌激素和次要女性性激素。 It is one of three major endogenous estrogens, the others being estradiol and estrone.它是三種主要的內源性雌激素之一，其他是雌二醇和雌酮。 Levels of Estriol Micronized in women who are not pregnant are almost undetectable.未懷孕婦女中的雌三醇微粉化水平幾乎無法檢測到。 However, during pregnancy, Estriol Micronized 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 Micronized are similar to those of other estrogens due to a relatively high rate of metabolism and excretion.然而，在妊娠期間，雖然通過相對較高的新陳代謝率和較高的雌激素水平，環己烯醇微粉化後的水平與其他雌激素相似，但胎盤素合成的雌三醇量很高，並且是迄今為止人體中產生最多的雌激素。排泄。 Relative to estradiol, both Estriol Micronized and estrone have far weaker activity as estrogens.相對於雌二醇，微粉化的雌三醇和雌酮的雌激素活性均弱得多。
