The egg is the seed of life produced by a woman’s ovaries, and her happy ending is to meet and combine with the “true sperm” to form a new life form. However, the reality is often very “bone-dry”, and many eggs cannot wait for such a day. Abortive death: Very few eggs grow to maturity in a woman’s lifetime, and the vast majority of the remaining eggs die prematurely on their journey to maturity. There are three ways in which they die – before a normal girl is born, there are millions of tiny eggs (primary oocytes) in her ovaries. As she ages, the eggs do not increase in number, but die in large numbers. Because it takes too much energy and time to “grow” an egg, the “mother ovary” has limited energy and has to give up most of her children, letting them die at birth. By the time they reach sexual maturity, there are only about 100,000 eggs left. It is at this stage that the highest percentage of eggs die. In addition, the egg soaks in a follicle and can develop and mature in the presence of sex hormones. However, there is usually only one egg that can develop and mature each month. In a woman’s lifetime, the number of eggs that can mature is about 400, and the rest of the eggs die on their own before they reach the maturity stage. Another type of premature death is more “equal”. In women with polycystic ovary syndrome (PCOS), there are basically no eggs left to mature each month. Holding back: Mature eggs are not always “safe and sound”. If an egg matures because of hormonal problems, but cannot break through the follicle, it will eventually die in the follicle. Unbroken follicle luteinization, this is the unruptured follicle luteinization syndrome. 1, bored to death: some eggs matured although can be successfully discharged from the follicle, but at this time complacent, but also too early. Some women suffer from chronic salpingitis, the umbilical part of the fallopian tube near the ovary, adhesion occurs, the opening of the umbilical end is closed, and even the umbilical structure is missing, then the formation of tubal hydrops. In this case, the egg how can not enter the fallopian tube, had to be in the fallopian tube around the ovary “around”, until the end of life. 2, exhaustion: some women’s fallopian tube inflammation is not serious, the egg can enter the fallopian tube cavity. However, the fallopian tubes are affected by inflammation, curved, seemingly through not through. Egg after a long swim, neither can meet the “real sperm”, but also can not go to the head, until exhaustion in the fallopian tube. 3, die alone: an egg after a lot of hard work finally through the fallopian tube, but did not meet the “real sperm”. To the uterus is still alone and suffering, and finally with the “aunt” to the wonderful world outside. Unfortunately, it was eventually discarded in the trash.
