Compulsive sexual behavior disorder (CSBD) and problematic pornography use (PPU) have garnered increasing attention as clinically significant conditions, potentially falling within the spectrum of behavioral addictions or impulse control disorders. However, neuroimaging findings to date have been inconsistent and scattered across studies, limiting our understanding of the neural mechanisms underlying these conditions. This protocol outlines a systematic review and coordinate-based meta-analysis (CBMA) designed to synthesize structural and functional neuroimaging results related to CSBD and PPU. By aggregating stereotactic coordinates from eligible studies, we aim to identify convergent patterns of brain alterations, particularly in regions implicated in reward processing, executive control, and salience attribution. The inclusion of both resting-state and task-based imaging data is expected to improve statistical power and facilitate a more integrative characterization of the neural correlates of CSBD and PPU. Findings from this review may help clarify the extent to which these conditions share neurobiological features with other addictive behaviors. This will advance theoretical models of dysregulated sexual behavior and inform future diagnostic and therapeutic strategies.
