Sibling incest resulting in pregnancy: A forensic case study of paternal neglect and pornographic exposure

Abstract

This case report presents a rare incident of sibling incest resulting in pregnancy, occurring within a context of paternal neglect and inadequate parental supervision. A 14-year-old boy, after unsupervised exposure to pornographic content on his father's mobile device, engaged in sexual intercourse with his 15-year-old sister. The case highlights the psychological and developmental risks posed by early and unregulated access to sexually explicit material. It also underscores the diagnostic, ethical, and legal challenges in the detection and forensic evaluation of intrafamilial sexual abuse. This report emphasizes the urgent need for preventive strategies, including parental controls, digital literacy training, and age-appropriate sexual education.
