The IUD (Intra Uterine Device) is not a barrier method and does not protect against sexually transmitted diseases. In fact, in some women, it may favor them, compromising future fertility. The IUD is an intrauterine device that must be inserted by a gynecologist into the uterine cavity (a thread is left in the vagina for easy recovery). It should be changed every 3-5 years. The IUD is a contraceptive that prevents implantation of a fertilized egg using multiple mechanisms. However, it constitutes a possible pathway for germs in the vaginal cavity to enter the uterine cavity, and is therefore not recommended for women who have not had children, especially if they have multiple sexual partners.
