摘要目的:探讨左炔诺孕酮宫内缓释系统（LNG-IUS）对育龄妇女性功能及性生活质量的影响。方法:以放置宫内节育器（IUD）进行长期避孕的育龄妇女为研究对象，根据避孕方式的选择，分为LNG-IUS组和含铜节育器（Cu-IUD）组，两组放置前与放置两年后分别进行性功能和性生活满意度调查随访，并评估放置后女性性功能情况。最终，203名妇女完成随访，其中LNG-IUS组130名，Cu-IUD组73名，两组按随访时年龄各分为3个亚组：20~29岁组，30~39岁组，40~49岁组，各亚组间的年龄比较差异无统计学意义（ P>0.05）。 结果:30~39岁组的LNG-IUS使用者中有17.1%报告性生活频率较前减少，显著高于同年龄组Cu-IUD使用者（3.4%），结果比较差异有统计学意义（ P<0.05）。其余各年龄亚组中，比较LNG-IUS和Cu-IUD放置前后的性生活频率变化和性生活满意度变化，差异均无统计学意义（ P>0.05）。两组人群放置后的性功能各项评分和总分比较差异均无统计学意义（ P>0.05）。 结论:LNG-IUS对育龄妇女性功能及性生活质量无不良影响。

abstractsObjective:To investigate the effects of levonorgestrel releasing intrauterine system (LNG-IUS) on sexual function and sexual quality in women of childbearing age.Methods:A total of 203 healthy women who were using IUD for long-term contraception were enrolled in the study. Among them, 130 were placed LNG-IUS as the study group and 73 were placed the copper intrauterine devices (Cu-IUDs) as the control group. The two groups were further divided into three subgroups by age. The basic information and questionnaires were adopted before and 2 years after using IUDs, including age, the time of using IUD, side-effects after using IUD, frequency and satisfaction of sex after using IUD. The Female Sexual Function Index (FSFI) was evaluated on 2 years after.Results:In the 30-39 age subgroup, the frequency of sex was significantly decreased after using LNG-IUS ( P<0.05). Rests of the subgroup shows no significantly different in the frequency of sex ( P>0.05). The sexual satisfaction in all subgroups also shows no significantly different before and after using IUDs ( P>0.05). There was no significant difference in the individual score and total scores of FSFI between the study group and control group ( P>0.05). Conclusion:The LNG-IUS has no adverse effects on female sexual function and sexual quality in the reproductive age.
