IUD is a T-shaped gadget that is placed up into the uterus of the woman. The IUD is not the most common birth control method, of course, as the pill remains the preferred option. It is also not always recommended for those women who may want to start a family one day, as IUD can cause infertility after using it for the five years or so it is fashioned in the uterus.
Another disadvantage of IUD is that it may cause more prolonged and more uncomfortable periods. The IUS, on the other hand, works the same, as it is also fitted effortlessly into the uterus. However, the significant difference between the two is that it releases the hormone progesterone. The hormone released from the device and into the woman is the same as the natural hormone.
Women who have this device inserted in them tend to have shorter and less painful periods than those on which IUD tend to have. It is crucial to keep in your way of thinking that while both are reputable forms of birth control, neither protects you against sexually transmitted diseases.
