How to prevent pregnancy with IUD?

Every woman will get pregnant. Being pregnant and having a child is a happy thing, which can form a complete family. But it does not mean that you can have children without restraint. Due to family planning, you need to take certain contraceptive measures after giving birth to prevent pregnancy again. IUD insertion is a contraceptive measure chosen by many women, which can reduce a lot of trouble, but many people do not understand how it works as a contraceptive. In fact, they should also pay attention to their own physical health. How to prevent pregnancy after having an IUD inserted?

"IUD insertion" is the most commonly used long-term contraceptive measure for women of childbearing age in my country. Often, an IUD can be placed in the body for more than ten years. IUD placement itself is a minor operation, placing a foreign object in the uterine cavity, and it takes a period of time for the body to adapt.

The scientific name of the "ring" is intrauterine device, abbreviated as IUD. It is placed in the uterine cavity of women of childbearing age, and achieves the purpose of abortion and contraception through mechanical stimulation and interference of chemical substances. It does not inhibit ovulation and does not affect the female endocrine system, thus avoiding the adverse reactions of general drug contraceptives. After years of practical improvement, most of the IUDs currently used in clinical practice are copper-containing or drug-containing IUDs. The stent materials are plastic, polyethylene, memory alloy, etc., and the shapes are not single, including round, T-shaped, V-shaped, Y-shaped and chain-shaped. IUDs made of different materials and in different shapes have their own characteristics, and therefore can be suitable for women with different physiques and needs.

Under normal circumstances, the most recent time for a woman to have an IUD inserted is within 3-7 days after the end of menstruation. At this time, the endometrium is thinner and is in the proliferation stage, and the slight damage caused by the IUD can be repaired quickly. In addition, the cervix is ​​tighter at this time, so it is not easy to fall off after insertion. To avoid infection, you should avoid sexual intercourse within one week before having the IUD inserted. If an unexpected pregnancy occurs and an abortion is required, an IUD can be inserted immediately after the abortion. At this time, performing abortion and IUD insertion at the same time is not only convenient for women, but also reduces their psychological burden. If it is inserted during delivery, it can be placed during the postpartum check-up 42 days after delivery. Because at this time, the uterus has basically returned to its normal size before pregnancy, the cervix is ​​loose, and it is easy to insert the IUD. At the same time, if sexual life has not been resumed after delivery, "hidden pregnancy" can be ruled out. If the delivery method is cesarean section, then it can be inserted during the cesarean section. If the IUD is inserted at this time, the ring can be placed in the best position in the uterus without increasing the patient's pain and mental burden, and can also avoid "hidden pregnancy" after delivery. In addition, the IUD insertion operation does not go through the vagina during cesarean section, and the cesarean section operation itself requires strict aseptic operation, so infection will not occur.

How to prevent pregnancy with IUD

The mechanism of human pregnancy is that the female ovary releases an egg, the egg is fertilized in the ampulla of the fallopian tube, and then develops into an embryo (morula) in the fallopian tube. The embryo is then released into the uterus to implant and grow. Contraception is about blocking any of these steps. The contraceptive principle of the intrauterine device (IUD) is: when an embryo wants to implant in the uterus, the constantly moving IUD scrapes the uterine wall, causing aseptic inflammation of the uterus, making it impossible for the embryo to implant and conceive normally in the uterus, thereby causing miscarriage to achieve the purpose of contraception. The essence of the intrauterine contraceptive ring (IUD) is a long-term, mild curettage abortion procedure, and it is the first choice for Chinese women to have contraception after marriage.

Through the above introduction, everyone knows that the principle of IUD contraception is actually to block the embryo from implanting in the uterus, thereby achieving the contraceptive effect. Therefore, it is a relatively scientific and safe contraceptive measure. Many hesitant women or people who are worried about its safety can get an IUD installed with confidence, but they need to pay attention to postoperative matters after the installation to ensure that no unexpected situations occur.
