How does the IUD prevent pregnancy?

There are many contraceptive methods now, and everyone can choose the one that suits them. This can not only prevent unwanted pregnancy but also reduce bacterial infection. Don't forget to protect yourself while enjoying the pleasure, especially female friends. You can discuss with your partner that condoms are not only worn by women. Men can wear them for better contraception. Married people with children can choose IUDs, which are inserted into the uterus and will not affect the sexual process.

1. "Intrauterine contraception" is the most commonly used long-term contraceptive measure for women of childbearing age in my country. When an embryo wants to implant in the uterus, the continuously moving contraceptive ring scrapes the uterine wall, causing aseptic inflammation of the uterus, making it impossible for the embryo to implant normally in the uterus and conceive, thus causing miscarriage to achieve the purpose of contraception. The essence of the intrauterine contraceptive ring (contraceptive ring) is a long-term and gentle curettage abortion, and it is the first choice for Chinese women to use for contraception after marriage.

2. After the IUD is inserted into the uterine cavity, in addition to acting as a mechanical barrier, the endometrium in contact with the IUD will produce a mild chronic, non-bacterial inflammatory response, causing the white blood cell count to increase by 3 to 11 times compared to women without IUDs, which is not conducive to the implantation of the fertilized egg. Another reaction of the contraceptive ring is the foreign body reaction, which involves the production of a large number of foreign giant cells and macrophages. In addition to swallowing up sperm entering the uterine cavity and embryos before implantation, they can also have a toxic effect on the embryos.

3. The principle of the steel-belt contraceptive ring is to increase the aseptic inflammation of the endometrium through the release of copper ions in the contraceptive device; enzymes are a necessary condition for implantation, and the contraceptive ring can interfere with the enzyme system of the endometrium, thereby reducing the activity of some enzymes in the secretory endometrium; it can also change the biochemical composition of cervical mucus and affect the activity or survival of sperm. These changes all increase the anti-fertility effects.

4. The progestin contraceptive ring interferes with the normal cyclic changes of the endometrium through the release of progesterone, causing the endometrium to have a higher level of progesterone, thereby causing the gland to atrophy. The interstitial degeneration is not conducive to implantation; it may also affect the transport or survival of sperm;

I hope the above can provide you with a reference and help you understand the principle of contraception using contraceptive rings. If you are married and have children and do not want to have another child for the time being, you can choose this method. There is no danger in having an IUD inserted in a regular hospital. When you want to have another child, you just need to take it out and recuperate for a few days. If there is no discomfort in your body, you can have a baby. The IUD should be removed one week after the end of the menstrual period.
