The egg, the seed of life produced by a woman’s ovaries, has its happiest ending when it meets and unites with the true sperm to form a new life form. However, the reality is that almost all eggs cannot wait for such a day. (1) In a normal girl, there are millions of tiny eggs (primary oocytes) in the ovaries before birth. As she ages, the number of eggs does not increase accordingly, but instead dies in large numbers. There is no way around it, raising an egg is too energy and time consuming, and ovarian mothers have limited energy and have to give up the vast majority of their children, who die at birth. By the time they reach sexual maturity, there are only about 100,000 eggs left. At this stage, the largest percentage of eggs die; (2) the eggs are bubbled in the follicles and can develop and mature under the action of sex hormones. However, only one egg can mature each month, and the number of eggs that can mature in a woman’s lifetime is about 400. For example, in women with polycystic ovary syndrome, there are basically no eggs to mature each month, and the eggs grow a little bit in size and grow out of existence. If a woman’s body has hormonal problems, her eggs mature but cannot break through the follicles, so she ends up dying in the follicles, and the unbroken follicles become luteinized, which is called unruptured follicle luteinization syndrome (LUFS syndrome). 3. Boredom and death Some eggs mature and are expelled from the follicle smoothly, but don’t be happy too soon. Some women have chronic tubal inflammation and the umbilical part of the fallopian tube near the ovary becomes adherent and closes the opening of the umbilical end, and even the umbilical structure is missing, forming a hydrocele in the fallopian tube. Then the poor egg, how can not enter the fallopian tube, but in the fallopian tube around the ovaries boring circles, until the end of life. Some women’s tubal inflammation is not so severe that the egg can enter the tubal lumen. However, the fallopian tube is still affected by the inflammation, bending and curving, seemingly through and not through, walking and walking, neither meeting the real sperm, nor walking head, until they die of exhaustion in the fallopian tube. 5, die of loneliness Well, one egg finally passed through the fallopian tube after a lot of hard work, but did not meet the real sperm, to the uterus is still alone and miserable, self-pity, finally followed the aunt to the wonderful world outside, but, unfortunately, in the aunt towel was discarded to the garbage. 6, happy death The egg, in life there is always the possibility of waiting for their true life sperm, if in the fallopian tube met, love, combined, although the egg disappeared, but the achievement of a new life form, really happy death. But this happiness is for the egg, for women, sometimes it is not necessarily happiness. There is another kind of egg, more noble, chasing her sperm if the quality is not high, crooked, she would rather be alone, high and cold to death. 8, freezing death Since the introduction of IVF, the egg has more than one way to die. The eggs that come out of IVF may not be used for a while, so they will be frozen in liquid nitrogen to be thawed in the future. But not all eggs are so lucky, some are frozen to death without a future date.
