What is the principle of women wearing rings

The IUD is a long-term contraceptive method that many women prefer. Using this method requires going to the hospital for a very simple operation, which is to insert an IUD into the uterus. The IUD has many functions and can achieve the purpose of contraception. How does the IUD prevent pregnancy? Below we will introduce the basic principles and common problems of contraception.

1. Mechanical equipment function

As a foreign body, it causes a mild, chronic, non-bacterial inflammatory sensation in the uterine wall, thereby changing the extracellular fluid of the uterus and preventing the implantation of the fertilized egg.

2. Tissue cell efficacy

It is mainly the macrophages and neutrophils that fully play the role of engulfing and destroying sperm.

3. Effects of inflammatory cells

When the degenerative substances of inflammatory cells reach a certain concentration, they harm the test tube embryo and make it impossible for it to continue to grow.

4. Prostacyclin efficacy

The IUD can stimulate the endometrium in the uterine cavity to produce prostacyclin, which makes the uterus and fallopian tubes contract and peristalsis abnormal, and at the same time increases the effect of estrogen, making the uterine cavity environment unfavorable for embryo implantation.

5. Efficacy of active substances

The contraceptive ring can be made of copper metal. It can achieve the purpose of contraception through the partial transformation of the endometrium, intrauterine fluid and other extracellular fluids in the uterine cavity, and its toxic effect on sperm.

FAQ: In the first few months after the ring is placed, it is most likely to be rejected and cause it to fall off. Therefore, women should go to a regular hospital to get an IUD, and cooperate with it in their daily life. For example, you should rest for two days after the IUD is placed, avoid physical labor and activity within a week, and refrain from sexual intercourse and sitz baths within two weeks. Go to the hospital for a check-up once after the first menstruation, and then have a follow-up visit after 6 months, and then every year.

The above are some explanations of the basic principles of contraceptive ring insertion. In addition, I would like to remind everyone that clinical experiments have concluded that after the contraceptive ring is inserted, patients generally have symptoms of lower abdominal pain or back pain. This is mainly because after the IUD is inserted, a small number of women will experience mild lower abdominal pain or back pain, which will disappear on their own after a short period of adaptation.
