Types of contraceptive rings

The contraceptive ring is mainly an intrauterine contraceptive device placed in the uterus to produce a contraceptive effect. It is mainly in a ring shape and is also called a contraceptive ring. It mainly acts locally with less interference to the body. After removal, it affects some reproductive health. It is a safe and reversible contraceptive tool. Contraceptive rings are mainly used frequently in daily life. There are many types of intrauterine contraceptives in China, mainly some intrauterine contraceptive rings, hormone-releasing intrauterine contraceptive rings and intrauterine devices, as well as some intrauterine devices containing progestin.

The main principles of the belt ring are: The woman releases some eggs, which can be fertilized in the fallopian tubes. The contraceptive ring mainly helps the embryo to develop into an embryo and keep moving in the uterus. Prevent the combination of egg and sperm and the implantation of the fertilized egg, thus achieving the effect of contraception.

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 above are the types of contraceptive rings. There are many types of intrauterine contraceptive rings in China, most of which are hormone-releasing intrauterine contraceptive rings. Once the ring rubs against the uterine wall, the fertilized eggs in the uterine wall cannot implant normally, so the ring is also a relatively key contraceptive measure. The IUD is also a common, safe and effective contraceptive tool that can be used for a long time.
