How long does an IUD or LNG IUS last?

Once fitted a LNG-IUD can be used for 3-8 years, depending on the brand.

After a Cu-IUD is fitted it works for 5-10 years, depending on the brand.

Both  Cu- IUD and LNG-IUD can be taken out sooner if you choose. Your fertility returns to normal as soon as the coil is removed.
