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

## TL;DR

This study reviews factors affecting sexual dysfunction in women during the first year after childbirth, highlighting physical and psychological influences.

## Contribution

The paper systematically identifies and synthesizes key determinants of postpartum sexual dysfunction within the first 12 months.

## Key findings

- Perineal trauma and early pain are consistently linked to worse sexual outcomes.
- Breastfeeding is associated with lower early sexual function and higher dyspareunia.
- Partner and family support correlate with better sexual function scores.

## Abstract

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.
