背景介紹：

雌二醇是天然雌激素的主要成分之一，是月經(jīng)周期中分泌的主要雌激素。血清雌二醇水平在卵泡期處于低水平，逐漸升高，直到排卵前一天左右，雌二醇水平出現(xiàn)顯著上升(排卵高峰)。雌二醇水平在排卵時或排卵后迅速下降，并再次處于卵泡期水平之內(nèi)。雌二醇在周期的第21天(黃體峰)有第二次上升。然后在下一個月經(jīng)周期開始時逐漸下降到最低水平。
Estradiol is one of the main components of naturally occurring estrogens and is the major estrogen secreted during the menstrual cycle. The serum levels of estradiol are low during the follicular phase rising gradually until about one day before ovulation when a marked rise in the estradiol level occurs (Ovulatory Peak). The estradiol level falls rapidly at, or right after ovulation and is again within the levels of the follicular phase. There is a second rise of estradiol around day 21 of the cycle (Luteal Peak). The levels then decline gradually to the lowest level at the onset of the next menstrual cycle.
