The intrauterine device is used either as a method of contraception or for therapeutic purposes. As a method of contraception, it consists of an coil comprising copper and one or two plates (depending on the type of coil) made of a special material compatible with the environment of the uterus.

It is placed in the first 5 days of the period if a gynaecological examination has preceded both with regard to the anatomy of the genital system and the confirmation of the absence of infections. It is placed with a special guide by the doctor, without the use of anaesthesia, provided the woman has already given birth. It is best avoided on women who have not given birth.

The hormonal IUD is used for therapeutic purposes, which releases a certain daily amount of progesterone. It is recommended in cases of uterine bleeding which have hormonal or idiopathic (unexplained) aetiology.

The duration of the spiral is 3-5 years depending on the type. It is removed at the end of menstruation and two tests are performed, cytological examination (Smear Test of intrauterine material) and culture of the IUD for microbiological examination. Replacement is possible in the next menstruation if the results of the above tests allow it or after treatment where necessary.
