Determinants of Postpartum Sexual Dysfunction in the First Year: A Systematic Review.

Background and

Objectives

This systematic review synthesized somatic and psychosocial determinants of postpartum sexual dysfunction (PSD) during the first 12 months after childbirth.

Methods

Following PRISMA 2020 guidelines, we searched PubMed, Web of Science, and Scopus from inception to 4 August 2025 without language limits for the indexed records. Eligible studies enrolled postpartum women (≤12 months) and reported validated sexual outcomes (FSFI/FSFI-6, PISQ-12), dyspareunia, or sexual activity, examining breastfeeding, partner support/body image, perineal trauma/instrumentation, or postpartum perineal/musculoskeletal pain. Two reviewers independently screened and extracted data; risk of bias was assessed with a modified Newcastle-Ottawa Scale.

Results

Of 1127 records screened, 15 studies were included. Perineal morbidity and early pain consistently tracked with worse sexual outcomes; assisted vaginal birth increased 6-month dyspareunia odds (OR 2.5). Breastfeeding was often associated with lower early sexual function and higher dyspareunia (6-month dyspareunia OR 4.4), with attenuation by 12 months. Higher partner/family support and more positive body image correlated with better FSFI scores. Heterogeneity in timing, measures, and adjustment precluded meta-analysis; results were narratively synthesized.

Conclusions

Perineal trauma and early pain are dominant risk signals; breastfeeding-related symptoms exert early and context-dependent effects; psychosocial resources are protective.
