背景介紹：
總雌激素包括雌酮、雌二醇和雌三醇的總量。雌激素參與了女性性器官的發(fā)育和第二性征的發(fā)生。在卵子受精之前，雌激素的主要作用是影響生殖道的生長(zhǎng)和功能，為受精的卵子做準(zhǔn)備。在月經(jīng)周期的卵泡期，總雌激素水平略有升高?？偞萍に氐漠a(chǎn)生隨后顯著增加，在第13天左右達(dá)到高峰。峰值持續(xù)時(shí)間短，到第16天的周期水平將會(huì)很低。第二個(gè)高峰出現(xiàn)在周期的第21天左右；如果不進(jìn)行受精，總雌激素的產(chǎn)生就會(huì)減少。在絕經(jīng)后婦女，所有雌激素的濃度顯著降低，雌激素成為主要的雌激素。在孕婦中，所有雌激素的濃度上升，雌三醇成為主要的雌激素。
Total estrogens comprise the total quantity of estrone, estradiol, and estriol. The estrogens are involved in the development of female sex organs and secondary sex characteristics. Before the ovum is fertilized the main action of the estrogens is on the growth and function of the reproductive tract to prepare it for the fertilized ovum. During the follicular phase of the menstrual cycle the total estrogens level shows a slight increase. The production of total estrogens then increases markedly to peak at around day 13. The peak is of short duration and by day 16 of the cycle levels will be low. A second peak occurs at around day 21 of the cycle; if fertilization does not occur, the production of total estrogens decreases. In post-menopausal women the concentration of all estrogens decreases substantially and estrone becomes the predominant estrogen. In pregnant women the concentration of all estrogens escalates and estriol becomes the predominant estrogen.
