The chances of getting pregnant with an IUD mainly depends on the type of IUD, with the copper-containing IUD having a contraceptive effectiveness rate of more than 90% and the drug-containing IUD having an effectiveness rate of more than 99%.
Currently, IUDs are commonly used as active IUDs, including copper-containing IUDs and drug-containing IUDs.
1. Copper-containing intrauterine device (IUD): this device mainly achieves contraception through the continuous release of biologically active copper ions in the uterus, which are highly resistant to fertility. The contraceptive effect of copper-containing IUD is proportional to the surface area of copper, and the contraceptive efficiency is usually above 90%, with the main clinical side effect of vaginal bleeding.

Among them, levonorgestrel intrauterine device is more than 99% effective, and the main side effect is menstrual changes, which will return to normal after the removal of the device.
