Summary: From eroding the prefrontal cortex, an area of the brain critical for impulse control, to damaging the dopamine reward system, researchers evaluate the impact of viewing pornography on the brain.
Pornography has existed throughout recorded history, transforming with the introduction of each new medium. Hundreds of sexually explicit frescoes and sculptures were found in the Mount Vesuvius ruins of Pompeii.
Since the advent of the internet, porn use has skyrocketed to dizzying heights. Pornhub, the world’s largest free porn site, received over 33.5 billion site visits during 2018 alone.
Science is only just beginning to reveal the neurological repercussions of porn consumption. But it is already clear that the mental health and sex lives of its widespread audience are suffering catastrophic effects. From depression to erectile dysfunction, porn appears to be hijacking our neural wiring with dire consequences.
In my own lab, we study the neural wiring that underlies learning and memory processes. The properties of video porn make it a particularly powerful trigger for plasticity, the brain’s ability to change and adapt as a result of experience. Combined with the accessibility and anonymity of online porn consumption, we are more vulnerable than ever to its hyper-stimulating effects.
Impacts of porn consumption
In the long term, pornography seems to create sexual dysfunctions, especially the inability to achieve erection or orgasm with a real life partner. Marital quality and commitment to one’s romantic partner also appear to be compromised.
To try to explain these effects, some scientists have drawn parallels between porn consumption and substance abuse. Through evolutionary design, the brain is wired to respond to sexual stimulation with surges of dopamine. This neurotransmitter, most often associated with reward anticipation, also acts to program memories and information into the brain. This adaption means that when the body requires something, like food or sex, the brain remembers where to return to experience the same pleasure.
Instead of turning to a romantic partner for sexual gratification or fulfillment, habituated porn users instinctively reach for their phones and laptops when desire comes calling. Furthermore, unnaturally strong explosions of reward and pleasure evoke unnaturally strong degrees of habituation in the brain. Psychiatrist Norman Doidge explains:
“Pornography satisfies every one of the prerequisites for neuroplastic change. When pornographers boast that they are pushing the envelope by introducing new, harder themes, what they don’t say is that they must, because their customers are building up a tolerance to the content.”
