Sexual dysfunction and mode of delivery in Chinese primiparous women: a systematic review and meta-analysis

BACKGROUND Up to now, there is controversy over the effect of delivery mode cesarean delivery and spontaneous vaginal delivery on sexual function. Therefore, we did a systematic review and meta-analysis in postpartum women to explore the mode of delivery, cesarean delivery, and spontaneous vaginal delivery and differences in postpartum sexual function (short- and long-term) in Chinese primiparous women. METHODS Comprehensive electronic searches of PubMed, EMBASE, Web of Science, Elsevier Science Direct, Cochrane Library, the Chinese Biological Medical Literature database and the Chinese National Knowledge Infrastructure database were conducted to identify any study in each database published to August 31, 2017. The primary outcome was the sexual satisfaction and the secondary outcomes were resumed intercourse and sexual pain in the postpartum. RESULTS We identified 10 studies with a total population of 2851 in the present meta-analysis. Five and six eligible articles were respectively included for sexual satisfaction in postpartum at 3- and 6 months. Compared with vaginal delivery group, two time points were all not found statistically significance (OR 1.53, 95%CI 0.93-2.49; OR 1.15, 95%CI 0.95-1.39, respectively) in cesarean and spontaneous vaginal delivery group; in resumed intercourse and sexual pain domains, they were all significantly, with an overall OR of 2.05 (95%CI 1.36-3.11) at 3 months, 1.50 (95%CI 1.04-2.16) at 6 months and 0.29 (95%CI 0.24, 0.36) at 3 months, 0.73 (95%CI 0.58, 0.93) at 6 months, respectively. With the passage of time, the gap was closing. Sensitivity analysis was indicated a good stability of the meta-analysis in each domain. CONCLUSIONS In conclusion, this meta-analysis indicated that the mode of delivery, cesarean and spontaneous vaginal delivery did not affect postpartum sexual satisfaction (short- and long-term) and appeared to have minimal effect on the long-term resumed intercourse and sexual pain in Chinese primiparous women. Primiparous women should be more cautious to choose cesarean section in order to preserve sexual function.
