title: The levonorgestrel-releasing intrauterine system in modern gynaecology.
abstract: The levonorgestrel-releasing intrauterine system was initially developed for contraception but is now widely used for a variety of gynaecological conditions. Compliance can sometimes be hampered by troublesome side effects (principally breakthrough bleeding) but appropriate counselling can reduce unnecessary discontinuation.
