促排卵没有怀孕者月经为什么会提前来潮呢？To promote ovulation not pregnant person menstruation why can you come in advance?2008-8-13

　　医生用卵泡刺激素(HMG或FSH)，促进多个卵泡发育和增加卵泡成熟度，目的是人工受精，或是做试管婴儿，也有在输卵管和精液正常的情况下，为了加速怀孕而促排助孕的。可是这些用过卵泡刺激素的人都有个奇怪的现象，那就是一旦助孕失败，月经就会提前来潮，短的提前3-4天，长的提前5-7天。这是否正常，又是为什么呢?

　　Doctors use follicle stimulating hormone(HMG or FSH) to promote the development of multiple follicles and increase follicular maturity. The purpose is artificial fertilization, or to be a test-tube baby, and to accelerate pregnancy in the case of normal fallopian tubes and semen. And promote pregnancy. However, these people who have used follicle stimulating hormone have a strange phenomenon, that is, once the pregnancy fails, menstruation will come in advance, 3-4 days in advance and 5-7 days in advance. Is that normal, and why?

　　这是正常现象，因为促排卵时，卵泡多个发育，每一个卵泡内分泌黄体酮的颗粒细胞也多些，一旦排卵颗粒细胞就转化形成多个黄体，黄体功能也强，分泌的黄体酮水平高于以往，内膜被迅速彻底转化成分泌期，如果没有受孕，就会很快脱落来月经。促排卵没有怀孕者月经会提前来潮也就不怪了，提前天数由排卵多少和卵子质量决定。

　　This is a normal phenomenon, because during ovulation, there are multiple follicles that develop, and there are more granular cells in each follicle endocrine progesterone. Once ovulation granule cells are converted into multiple luteal bodies, the luteal function is also strong, and the secretion of progesterone is higher than ever before., The inner membrane is quickly and completely transformed into a secretion period. If there is no conception, it will soon fall off and menstruate. Ovulation does not have pregnant people menstruation will come in advance is not weird, the number of days before ovulation and egg quality determine.
