It is medically recognized that “abortion is one of the risk factors for infertility”. The sudden cessation of pregnancy affects hormonal changes, and many women suffer from irregular periods and endocrine disruption after abortion, and even damage to the uterine lining and fallopian tubes, which can have an impact on future pregnancies. The cause is likely to be uterine adhesion syndrome, which refers to the presence of adhesions and/or fibrosis in the uterine cavity due to scarring. At one time the names also included: traumatic intrauterine adhesions, uterine/cervical atresia, traumatic uterine atrophy, sclerotic endometrium and endometrial sclerosis. This goes a long way to explaining why people who used to be able to get pregnant (but had abortions because they didn’t want to or couldn’t), where the trauma of the abortion and possible accompanying infections caused adhesions to develop in the uterus, later became sterile and infertile. A foreign study showed that the incidence of uterine adhesion syndrome was 25% among those who underwent cervical dilatation and clamping 1-4 weeks after delivery (which does not seem to be valid, but so it is), 30.9% among those who underwent an abortion due to an induced abortion, and 6.4% among those who underwent an abortion due to an incomplete abortion. Another study showed that 40% of women who had repeated curettage for incomplete abortion would develop uterine adhesion syndrome. The longer the interval between the loss of the fetus from an induced abortion and the curettage, the greater the likelihood of uterine adhesions due to fibrotic activity of the residual tissue. In addition, the number of scrapings also affects the incidence of uterine adhesions; studies have shown that the incidence of one scraping is 16%, whereas with three or more scrapings, the incidence may be as high as 32%; in fact, a single scraping maneuver sets the stage for the development of uterine adhesions as much as possible. Infertility is seen in about 40 to 50 percent of people with female factors, 30 to 40 percent with male factors, and 10 to 20 percent with both partners. Among the female factors, blocked fallopian tubes and endometrial problems are the most common. Almost 40% of infertility patients have a history of abortion. Most of these are due to thin or defective uterine lining, and the other part is due to blocked fallopian tubes, which prevented natural pregnancy and forced them to come for IVF. About 60% of the causes of tubal blockage are related to abortion, while the others may be related to reproductive tract infections or pelvic inflammatory disease. From this percentage, the probability of triggering tubal problems after abortion is high. The basic conditions for fertility require four components: healthy sperm, healthy eggs, smooth and well-functioning fallopian tubes for the sperm and eggs to meet and become fertilized eggs, and finally a fertile endometrial environment for the fertilized egg to become an embryo, which in turn develops into a fetus. IVF513 reminds to protect the fallopian tubes and ovarian function, fallopian tube problems, sperm and egg will not be able to meet, let alone carry a baby, ovarian recession without qualified eggs, do IVF is also easy to succeed. Note: Abortion jeopardizes the uterine lining? For abortion, there are mainly surgical abortion and medication abortion. The former is a mechanical method, using negative pressure suction, through the suction tube, the embryo will be forcibly sucked out of the uterus, the principle is a bit like using a vacuum cleaner to suck things, it is mainly used for the embryo within 70 days of menopause. Drug abortion is to take drugs, first let the embryo from the attached endometrium fall down, and then use drugs to promote uterine contraction, the embryo will be expelled from the body, mainly used for 49 days of menopause within the embryo. The principle seems simple, but in fact it is a test of the doctor’s experience. Once the operation is not done properly, it will damage the patient’s uterine lining, which is the soil for the embryo to settle in, and repeated abortions will make the functional layer of the uterine lining become thinner and poorer. When there is a problem with the soil, it is of course difficult for the seeds to germinate. In addition, abortion may also cause obstruction of the tubal orifice, affecting another pregnancy. Reminder: women must care for themselves A lot of people think it does not matter when they are young, abortion again and again, to really want to have children, but because of a variety of abortion complications can not conceive and regret. Warm reminder: 1, abortion is not a means of contraception. Emergency morning-after pill should not become a regular contraceptive method, recommended that men use condoms to contracept. 2, women must care for themselves. Women who have not given birth to a child, the first choice of abortion must be careful. Have no choice but to have an abortion, do not go to a small clinic to abort, must go to a regular hospital obstetrics and gynecology or family planning department to do abortion, to reduce the occurrence of abortion complications.
