There has been little research published on the impact of intrauterine contraceptive (IUC) methods on sexual functioning.
This study aimed: (i) to assess different aspects of sexual functioning, including the prevalence of sexual dysfunction in women using a levonorgestrel intrauterine system (LNG-IUS); (ii) to compare this prevalence with that among copper-releasing intrauterine device (Cu-IUD) users; and (iii) to identify the relationship between psychological variables and sexual functioning in women using one of the aforementioned IUCs.
In a multicenter cross-sectional study, 845 women with an IUC were invited to fill out a questionnaire. The latter was returned by 402 (48%) of them: 353 women were LNG-IUS users (88%) and 49 were Cu-IUD users (12%). The questions asked pertained to depression, well-being, marital relation quality, and sexual functioning.
Sexual functioning was measured with the short sexual functioning scale.
One-third of LNG-IUS users (33%) reported a sexual dysfunction. Of those, 20% reported an increased sexual desire, 25% a decreased sexual desire, 5% arousal problems, and 8% orgasm problems. Women using a LNG-IUS did not differ significantly in distribution, type, or prevalence (32.9% vs. 36.7%) of sexual dysfunction, nor in depressive symptoms (Beck Depression Inventory score; 4.7 vs. 3.9; P = 0.33), general well-being (WHO-5 well-being scale score; 16.8 vs. 17.7; P = 0.170), or partner relationship quality (Dyadic Adjustment Scale score; 107 vs. 108; P = 0.74) compared to Cu-IUD users. Overall, the perceived influence of IUCs on sexual functioning was in the lower range and did not differentiate LNG-IUS greatly from Cu-IUD-users.
Women using a LNG-IUS do not differ from those wearing a Cu-IUD with regard to psychological and sexual functioning. The perceived impact of IUD use on sexuality should not be overestimated.
关于宫内避孕器（IUC）方法对性功能的影响，研究甚少。
本研究旨在：（i）评估包括使用左炔诺孕酮宫内节育系统（LNG-IUS）的女性性功能障碍的流行率在内的不同方面的性功能；（ii）比较这一流行率与含铜宫内节育器（Cu-IUD）使用者的流行率；以及（iii）确定在使用上述 IUC 之一的女性中，心理变量与性功能之间的关系。
在一项多中心横断面研究中，邀请了 845 名使用 IUC 的女性填写问卷。其中 402 名（48%）女性做出了回应：353 名女性为 LNG-IUS 用户（88%），49 名女性为 Cu-IUD 用户（12%）。所提问题涉及抑郁、幸福感、婚姻关系质量和性功能。
性功能通过简短性功能量表进行评估。
三分之一的 LNG-IUS 用户（33%）报告存在性功能障碍。其中，20%的女性性欲增强，25%的女性性欲减退，5%的女性出现性欲唤起问题，8%的女性出现性高潮问题。使用 LNG-IUS 的女性在性功能障碍的分布、类型或流行率（32.9%与 36.7%）、抑郁症状（贝克抑郁量表评分；4.7 与 3.9；P=0.33）、一般幸福感（世界卫生组织-5 项幸福感量表评分；16.8 与 17.7；P=0.170）或伴侣关系质量（对偶调整量表评分；107 与 108；P=0.74）方面均无显著差异，与 Cu-IUD 用户相比。总体而言，IUC 对性功能的感知影响处于较低水平，并未将 LNG-IUS 与 Cu-IUD 使用者明显区分开来。
使用 LNG-IUS 的女性在心理和性功能方面与使用 Cu-IUD 的女性无差异。不应高估 IUD 使用对性生活的影响。
