Abstract
Abstract Background A growing body of research investigates the sexual functioning status in women with contraceptives use; however, the evidence is still inconclusive. Aim To examine whether contraceptives use is associated with a higher risk of female sexual dysfunction (FSD). Methods The electronic databases MEDLINE, Embase, Cochrane Library databases, and PsychINFO were systematically screened for eligible studies before December 2019. We only included those studies assessing women's sexual functioning by the Female Sexual Function Index (FSFI). This study was registered on the PROSPERO (ID: CRD42020167723, http://www.crd.york.ac.uk/PROSPERO). Outcomes The strength of the association between contraceptives use and risk of FSD was presented by calculating the standard mean dierences (SMDs) and the relative risk (RR) with a 95% confidence interval (CI). The pooled results were calculated using a random-effects model. Results A total of 12 studies (7 cross-sectional studies, 3 cohorts, and 1 case-control study) involving 9,427 participants were included. The mean age in the contraceptive users ranged from 22.5 ± 2.4 years to 38.2 ± 4.6 years, while the mean age in the nonusers was 22.5 ± 2.4 years to 36.0 ± 1.0 years. Pooled results showed that no significant difference in the total FSFI scores was observed between contraceptives use and noncontraception (SMD = −1.03, 95% CI: −2.08 to 0.01, P = .053; heterogeneity: I2 = 98.2%, P < .001). In line with this finding, the pooled RR also yielded no association between contraception use and the risk of FSD (RR = 1.29, 95% CI: 0.72–2.28, P = .392; heterogeneity: I2 = 76.0%, P = .0015). However, the subscale sexual desire showed a significant reduction in women who received contraceptives than those did not use contraception (SMD = −1.17, 95% CI: −2.09 to −0.24, P = .014; heterogeneity: I2 = 97.7%, P < .001), while no significant differences were found in sexual arousal, lubrication, orgasm, satisfaction, and pain domain. Clinical Implications Though evidence from this meta-analysis did not support an association between contraceptives use and the risk of FSD, the sexual desire could be significantly impaired by contraceptives use. Strengths & Limitations This is the first meta-analysis quantifying the relationship between contraceptives use and the risks of FSD. However, substantial heterogeneities were presented across the included studies. Conclusion No direct association between contraceptives use and the risk of FSD was found. Nevertheless, declining sexual desire was significantly associated with contraceptives use. Additional double-blind, randomized, placebo-controlled trials are still warranted.
