An intrauterine device, or intrauterine device, is a small device that is inserted into the uterine cavity. It is designed to prevent pregnancy for a long time.

Intrauterine device device

The IUD (intrauterine device) is T-shaped, but in most cases it is called a coil. During the 20th century, many types of IUDs were invented, but today 2 types are used:

- a spiral with copper;

- a spiral with hormones.

For the manufacture of the IUD, safe plastic is used, supplemented with thin copper wire or a container from which a small amount of progestin is released.

How does the intrauterine device work?

Both types of IUDs prevent the implantation of an egg into the wall of the uterus. The progestin-containing coil affects the ability of sperm to pass through the cervix and prevents ovulation. The intrauterine device with copper has a detrimental effect on the egg and sperm.

The sum of the various mechanisms of action provides 90% of the effectiveness of the intrauterine device. The progestin-containing coil can be in the uterine cavity for 2 years, and the coil with copper - up to 5 years.

Complications caused by an intrauterine device

The IUD can cause prolonged and heavy periods or bleeding in between. Inflammatory diseases of the appendages or uterus are possible, provoked by the development of bacterial infections, the likelihood of which is 2-3 times higher than without the use of the IUD. Very rarely, the installation of an intrauterine device can lead to perforation of the uterus - damage to its wall. Women with an intrauterine device may experience pain in the lower abdomen and discomfort during intercourse caused by pain.


It is not recommended to use the IUD in cases where there is inflammation of the appendages, heavy menstruation, and sexual activity is accompanied by the risk of contracting genital infections. Both nulliparous girls and women should be wary of this method of contraception.
