In an study published in JAMA Psychiatry in 2014, researchers have shown that it is possible that watching porn can literally shrink your brain. According to the report’s authors Dr. Simone Kühn and Dr. Jürgen Gallinat: “We found a significant negative association between reported pornography hours per week and gray matter volume in the right caudate (P < .001, corrected for multiple comparisons) as well as with functional activity during a sexual cue–reactivity paradigm in the left putamen (P < .001). Functional connectivity of the right caudate to the left dorsolateral prefrontal cortex was negatively associated with hours of pornography consumption.”
