Main findings
We systematically reviewed the literature on obstetric risk factors for sexual dysfunction up to one year after delivery, and assessed their effect estimate. Eligible studies were exclusively observational and we performed random-effect meta-analysis with subgroup analysis for sexual dysfunction, for the occurrence of dyspareunia and vaginal dryness. We did not find a significant effect of the mode of delivery. When assessing the effect of perineal trauma, we found that anal sphincter injury was associated with increased odds for both sexual dysfunction and dyspareunia, and that episiotomy was associated with dyspareunia. We found no association of vaginal dryness with any of the studied factors, neither between body image dissatisfaction and sexual function up to one year after delivery.
