According to the September 2009 edition of Playboy, watching porn boosts your testosterone levels as effectively as hormone therapy drugs.
Men lose and average of 1percent of their testosterone levels every year starting at age 30, and 5 million American men suffer from low testosterone. Among the array of detrimental effects this has on your penis, low hormone levels can cause you to shrink and become depressed.
Rutgers University sex researcher and biological anthropologist, Helen Fisher, suggests that while showing your wife and children affection decreases your testosterone, porn "drives up dopamine levels, which drives up your testosterone."
Will doctors start prescribing porn over medicine for "Low T" sufferers? Newsweek doesn't think so, pointing out that while exercise works as well as drugs at enhancing your mood, antidepressants are still abundant. In fact, there are several drug companies like Solvay Pharmaceuticals, that want "Low T" to be the next E.D. (erectile dysfunction). In so doing, they hope to create a market for testosterone drugs that rivals that for Viagra.
If you aren't into getting porn related computer viruses or taking hormone replacement drugs, German researchers have found several natural ways to do so: have erections, exercise, lose weight, start weight training early, eat a balanced diet, do heavy lifts, do at least three sets of each exercise, rest, avoid drinking more than three alcoholic drinks a day, don't skip meals, and sleep at least seven hours a night.
