Acceptability of the long-term contraceptive levonorgestrel-releasing intrauterine system (Mirena): a 3-year follow-up study

Contraception. 2003 Feb;67(2):87-91. doi: 10.1016/s0010-7824(02)00482-1.


This study investigated the long-term acceptability of a levonorgestrel-releasing intrauterine system (LNG-IUS) in 165 women after 6 and 36 months of use. Changes in menstrual bleeding pattern were experienced by 161 (98%) women, with a cessation or transient absence of menstruation occurring in 75 (47%) and 14 (9%) women, respectively. Amenorrhea was considered by most women (81%) as a positive change. The proportion of women with menstrual pain was reduced from 60% before use to 29% after 36 months of use with the LNG-IUS. Fear of an unwanted pregnancy became less widespread with duration of use and the device had no disturbing effects on the women or their partners during sexual intercourse. The number of women expressing that they were very satisfied with the LNG-IUS was 69% and 77% after six months and 36 months of use, respectively. LNG-IUS is a well-accepted contraceptive method, without negative influences on the sexual relationship between users and their partners, and is suitable for women requiring long-term reversible contraceptive protection.
