A survey of young women's perceptions of the influence of the Levonorgestrel-Intrauterine System or copper-intrauterine device on sexual desire.

OBJECTIVES

Few studies, with contradictory results, evaluate intrauterine contraceptives (IUC) and sexual function specifically. This study compares perception of sexual desire related to IUC use and aspects of sexual function in women who use the Lng-IUS with those using the Cu-IUD.

STUDY DESIGN

A secondary analysis regarding IUC use based on a larger cross-sectional survey of contraceptive use in Sweden, conducted in 2013. In total, 153 IUC users (103 Cu-IUD and 50 Lng-IUS users) answered the questionnaire. The only inclusion criterion was intrauterine contraceptive use.

MAIN OUTCOME MEASURES

Were self-reported sexual desire changes related to contraceptive method. We also analysed aspects of sexual functioning; sexual desire level, sexual activity, orgasm frequency, satisfaction with sex life and satisfaction of desire level.

RESULTS

A negative effect on sexual desire due to contraceptive method was reported by 28% of the Lng-IUS users and by 10.1% of the Cu-IUD users (p < 0.05). Results were more marked after adjusting for age, body mass index, depression, parity, switching behaviour, and partnership (OR 5.0; CI: 1.8-13.8). The adjusted odds of reporting low sexual desire level (never or almost never feeling sexual desire) (OR 3.5; CI: 1.1-11.2) as well as low satisfaction with sex life (OR 2.7; CI: 1.2-6.3) was higher in the Lng-IUS group (adjusted for same confounders as above).

CONCLUSIONS

The women in this study using the Lng-IUS more often report negative sexual desire effects of their contraception as well as lower sexual desire level compared with women using the Cu-IUD.
