Lydia Copper Y prevents pregnancy for up to 5 years. Unlike the Copper T, the special Y-shape makes it gentle during insertion and removal and it can be placed perfectly in the womb. This IUD is ideal for less-experienced health providers. For women, the unique shape makes the insertion process less painful. Lydia Copper Y also ensures that the provider will not touch the IUD (aseptic technique). This IUD is comfortable for many women including young women.
