Why Most Child Sexual Abuse Examinations Are Normal: Forensic Implications, Misconceptions, and Evidence-Based Communication.

Child sexual abuse (CSA) evaluations frequently yield normal or nonspecific anogenital findings, even in cases later substantiated through investigation. This reality is often misunderstood in clinical, legal, and multidisciplinary contexts, where the absence of physical injury may be incorrectly interpreted as the absence of abuse. The purpose of this narrative review is to explain why most CSA examinations are normal and to provide an evidence-based framework for interpreting and communicating these findings in a manner that is medically accurate and forensically defensible. A targeted review of contemporary guidelines, large clinical series, healing studies, forensic evidence collection literature, and sexually transmitted infection (STI) testing recommendations was conducted. Evidence consistently demonstrates that low physical yield is driven by several converging factors: the nature of abusive acts, the elasticity and rapid healing capacity of pediatric anogenital tissues, delayed disclosure leading to non-acute examinations, variability in examiner experience and documentation quality, and the time-sensitive nature of biological evidence recovery. STI findings are uncommon overall and require contextual interpretation, including consideration of testing methods and potential nonsexual transmission pathways. Importantly, a normal examination neither confirms nor excludes CSA. Misinterpretation commonly arises from imprecise terminology, binary reasoning, and overreliance on physical findings as proof. This review emphasizes the need for standardized, evidence-based communication in medical reports and testimony to prevent medico-legal misunderstanding. Practical language guidance is provided to assist clinicians in accurately conveying the limitations and significance of normal findings. Understanding that "normal is common" in CSA evaluations is essential to reducing harm, supporting trauma-informed care, and strengthening the integrity of multidisciplinary decision-making.
