The IUD will not affect a woman’s life. The IUD is mainly placed in the uterine cavity, and its effect is localized, so it will not affect other parts of the body, nor will it affect the body’s endocrine secretion, etc., so it has no effect on women’s life. The principle of contraception is that the endometrium is stimulated by a foreign body for a long period of time, which causes aseptic inflammatory reaction and prevents the fertilized egg from implanting, thus achieving the purpose of contraception. In addition, the foreign body reaction also damages the endometrium, which produces prostaglandins that alter the peristalsis of the fallopian tubes, causing the development of the fertilized egg to be out of sync with the endometrium. It should be noted that if some uncomfortable symptoms such as bleeding and lower abdominal pain occur after the placement of the ring, you should consult your doctor in time and follow the doctor’s advice.
