Gary and Marnia wrote this article for an academic journal called The Evolutionary Review. I couldn’t get a proper PDF of it, so here’s the galley proof for those of you who would like to read it: The Great Porn Experiment “The collision of widespread internet porn use with man’s ancient mammalian brain constitutes one […]

“Interesting factoid: I just did some calculations… Assuming an average of an hour and half a day of pornography from age 12 to 27, means I’ve watched roughly A YEAR of porn. Quite possibly significantly more. I’ve been off here and there but had my share of 6+ hour days.” […]

COMMENTS: Delta FosB is one the primary molecules of addiction. It rises, or accumulates, during an addiction process, reinforcing addictive behavior and rewiring of the brain. It rises whether the addiction is chemical or behavioral. This study shows that it accumulates during sexual activity and consumption of sugar. Researchers also found that sexual activity increased the consumption of sugar. Delta FosB may be involved in one addiction reinforcing another addiction. The question is – how does “over consumption” of porn affect Delta FosB?

COMMENTS: Basic premise is that addictions hijacks the pair bonding mechanisms shared by the reward circuitry. Porn addiction therefore likely affects the pair-bonding mechanisms in our brains.

Many porn users report that delayed ejaculation was a precursor to their erectile dysfunction. Years of porn use can cause a variety of symptoms, which when examined, lie on a spectrum. Desensitization of the reward circuitry is at the root of these various symptoms, which include:

How will you fill your pair-bonder “hole?” In recent years, scientists have been studying a fascinating mammal in greater depth: the prairie vole. There are many closely related vole species, but some species mate for life while others don’t form pair bonds at all (like most mammals). The prairie vole belongs to that curious 3 […]
