Background/Objective: Dyspareunia negatively affects women’s lives. Up to 35% suffer from postpartum dyspareunia. Many factors may influence the occurrence of postpartum dyspareunia, but little is known about them. This study aimed to look at the frequency of dyspareunia one year postpartum in a cohort of primiparae. Which perinatal factors influence the frequency of postpartum dyspareunia? Methods: A total of 3264 primiparae were included in this observational cohort study. Perinatal factors were documented, and a specially designed questionnaire was sent to them one year postpartum. The primary outcome was the frequency of dyspareunia one year postpartum. The secondary outcomes included potential influencing factors such as birthing method (spontaneous bed delivery, spontaneous delivery other than bed, water delivery, and vacuum-assisted delivery); perineal injuries (first- and second-degree perineal tears, obstetric anal sphincter injuries (OASIs), and episiotomies); and the use of oxytocin. Results: Postpartum dyspareunia was observed in 15% of the 3264 primiparae. In multivariate analysis, there were influences found in the perineal injury group, especially for first- and second-degree perineal tears and OASIs. In the oxytocin group, a trend toward a higher rate of postpartum dyspareunia was observed. No influence of the different birthing methods was found. Conclusions: Postpartum dyspareunia, affecting 15% of women one year after vaginal delivery, is associated with perineal injuries, particularly minor perineal tears and OASIs. This highlights the importance of good preparation of the perineum and pelvic floor before delivery, efficient perineal protection during labor, and the use of a precise repair technique for all perineal injuries.
