月经紊乱是女性妇产科的一个常见问题,要了解为什么会出现月经紊乱,首先要从正常的月经周期说起。子宫内膜周期性改变月经是女性性成熟的一个标志,每个月,子宫都在为怀孕做着准备工作。子宫内膜有一个功能层,每个月在卵巢的雌激素的影响下开始生长,到了月经中期长到一定的厚度,为可能的受精卵在子宫上的种植作好准备。在月经后半期,进入所谓的黄体期,卵巢分泌孕激素,支持可能的受精卵的发育,如果没有胚胎在子宫内种植,那么准备好的子宫内膜就开始脱落伴随出血,形成月经。排卵是个分界点子宫内膜的周期性改变,如上所述,是受卵巢分泌的激素调节的。卵巢在排卵前,以分泌雌激素为主,雌激素支持着子宫内膜的生长,在排卵后,形成一个黄体,黄体分泌孕激素。

Ovulation is a cut-off point of cyclical changes in the endometrium, as mentioned above, is regulated by ovarian hormone secretion. Ovary before ovulation, to secrete estrogen-based, estrogen supports the growth of the endometrium, after ovulation, the formation of a corpus luteum, progesterone secretion.
