Objective: This study aims to assess sexual function (SF) and quality of life (QoL) among women using copper intrauterine devices (Cu-IUD), levonorgestrel-releasing intrauterine system (LNG-IUS) or etonogestrel(ENG)-releasing subdermal implant.
Methods: This is a cross-sectional study involving 213 women who are sexually active, using Cu-IUD, LNG-IUS or ENG implant for at least one year. SF assessment was carried out through the Female Sexual Function Index (FSFI) and QoL was made through The Short Form Health Research.
Results: Frequency of sexual dysfunction score in Cu-IUD users was 33.8%; 47.2% in LNG-IUS users and 47.8% in ENG-implant users, without difference between groups. Desire domain had higher score in Cu-IUD users (Cu-IUD:4.20 ± 1.15 × LNG-IUS:3.76 ± 1.17 × ENG-implant:3.63 ± 1.15; p = .009). Between Cu-IUD and LNG-IUS users there was no difference in FSFI score. Total FSFI score was higher in Cu-IUD group when compared only to ENG-implant (Cu-IUD:27.48 ± 6.14 × Implant:25.07 ± 6.89; p = .029). Regarding the QoL score, difference was found only in general health domain (Cu-IUD:65.22 ± 14.91 × LNG-IUS:62.61 ± 19.04 × Implant:58.33 ± 16.46; p = .034), with lower score for implant group.
Conclusion: There was no difference in the SF total score between the users of Cu-IUD, LNG-IUS and ENG implant. However, the score of the FSFI desire domain and general health status were higher among users of the Cu-IUD.
