The intrauterine device (IUD) belongs to the barrier contraceptives. It’s a method that isn’t advisable for teens since it’s not really suitable for their needs. An IUD is a small device shaped like a T that is inserted into your uterus.
There are 2 kinds of IUDs. A copper IUD has a copper wire that changes the chemistry of your uterus and destroys sperm cells. A hormonal IUD destroys sperm cells with the help of hormones released into the uterus.
An IUD has the advantage of providing constant protection from unwanted pregnancies, and it only needs to be changed every 5 years. However, it can cause heavier periods and it doesn’t protect against BBSTIs. An IUD has to be inserted by your doctor during a gynecological examination.
