What is the ring like?

Inert intrauterine contraceptive device: made of stainless steel wire or plastic, silicone, such as metal single ring, twisted ring and stainless steel uterine ring.

Copper intrauterine device: It is the most widely used type of active intrauterine device, which uses the killing effect of copper on sperm or fertilized eggs to enhance the contraceptive effect.

Progestin-releasing intrauterine device: The progestin contained in the intrauterine device is slowly and steadily released into the uterine cavity, which improves the contraceptive effect and can significantly reduce bleeding.

Intrauterine devices that release hemostatic drugs: can effectively control the increase in menstrual volume after intrauterine device placement.

The foreign body effect of the intrauterine contraceptive device can cause asexual inflammation of the endometrium, thereby affecting the implantation of the fertilized egg. In addition to the above functions, the washable intrauterine contraceptive device also releases copper ions, which have a killing effect on sperm and embryos.

The intrauterine device containing progestin can release a small amount of progestin into the uterine cavity for a long time, causing the endometrium to atrophy, which is not conducive to the implantation of the fertilized egg. Both of these effects further enhance the contraceptive effect of the active intrauterine device.

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 use for contraception after marriage.
