Effects of progestin contraceptive methods on sexual function in reproductive age women: a meta-analysis

Abstract

Aim The aim of this study was to investigate the effects of progestin contraceptive methods on sexual function in reproductive-age women. Methods The published literature was identified via a systematic search in medical databases of PubMed, SCOPUS, ISI Web of Sciences, Embase, Cochrane library and Google Scholar up to December 2019 using relevant search terms. All randomized controlled trials or before-after studies which assessed the effects of progestin contraceptive method on sexual function in human were included in the analysis. Data extraction was done separately by two independent reviewers. A random-effects meta-analysis was performed to calculate the overall mean effect sizes. Heterogeneity was assessed using Q test and I2 index. Publication bias was performed by visual inspection of funnel plots and Egger bias test. Results A total of 5244 articles were found in primary search, of which 19 studies (N = 710 participants) met the inclusion criteria for the meta-analysis. The results of the random effects meta-analysis suggested no effect of implant on sexual function three months after insertion (WMD: 1.85; 95% CI: −0.34 to 4.04; p = .098). In contrast, this method has a positive effect on sexual function six months after insertion (WMD: 3.48; 95% CI: 2.78 to 4.19; p = .001). Furthermore, the results of random effects models indicated that there was no significant effect of LNG-IUS on female sexual function until 12 months after insertion (WMD: 3.20; 95% CI: −1.56 to 7.98; p = .188). Any evidence of publication bias was found. Conclusions The findings showed a positive or neutral effect of implant and LNG-IUS on female sexual function. Given the importance of examining sexuality in contraceptive users, this study provides new evidence, which can be offered to women during contraceptive counseling.
