What Guys Need to Know About Masturbation


Masturbation is natural and healthy. Over 94% of men masturbate1.

It feels good. It can reduce stress and tension by releasing endorphins, oxytocin, and dopamine, and it can even help you sleep2.

It helps young men to explore their bodies, and learn what they like and don’t like.

But most men know very little about masturbation, so we’re going to cut through the myths and misinformation, and answer some practical questions.

Does Masturbation Cause Erectile Dysfunction?

This is a common belief, but extensive studies have shown that masturbation has no effect on a man’s ability to achieve and maintain an erection. The International Society for Sexual Medicine3 says, “The notion that masturbation causes erectile dysfunction (ED) is a myth.”

It’s similar to the myth of “Porn Induced Erectile Dysfunction (PIED)” . (See our article, “Does Porn Cause Erectile Dysfunction?“)

You may have heard that masturbation lowers testosterone levels. This is based on a single study of ten men, and the results have not been replicated. Several other studies actually show the opposite: sexual activity and orgasms increase testosterone levels4

Additional Health Benefits from Masturbation

In addition to reducing stress and improving sleep, masturbation may actually have a measurable effect on reducing your risk of prostate cancer. Studies have found that men who ejaculate at least 5 times per week have a significantly lower risk than men who ejaculate less frequently (2 or fewer times per week)5 6, although researchers don’t understand why.

Researchers at the University of Sydney7 claim that masturbation improves immune functioning by increasing cortisol levels, which can regulate immune functioning in small doses. It also reduces depression by increasing the amount of endorphins in the bloodstream. They add that engaging in self-pleasure can also ‘lower the risk of type-2 diabetes (though this association may also be explained by greater overall health), reduce insomnia through hormonal and tension release, and increase pelvic floor strength through the contractions that happen during orgasm.

Masturbation also promotes blood flow, an important factor in the health of the penis. This is especially important for men who don’t have nighttime or morning erections, which are believed to be the body’s mechanism for ensuring an adequate blood and oxygen supply to the penis.

In fact, sex coach Jennifer Stephan8 points out that masturbation is especially important for men with ED:

Often times men believe that masturbating is pointless if they are no longer able to achieve an erection.

That couldn’t be further from the truth. 

So, let’s look at it from this perspective. You have a car and you aren’t able to drive it, but it has value. This means you have to maintain it. Wash it, keep gas in it, oil changes etc.

Your penis needs the same attention. First, with or without an erection you can have an orgasm.

Second, it’s important to continue masturbating even if you can’t get an erection. It will help you to maintain the length, because yes, you will lose length. Touch stimulates blood flow, nerves, arousal and continued intimacy. 

Are There Risks from Masturbation?

If you masturbate frequently, the penis can become irritated. To prevent this, use a good quality sex lube, or a lotion without scents or additives.

If you masturbate too vigorously, or if you bend or twist the shaft, it’s possible to fracture your penis, by rupturing the corpus cavernosa – the sponge-like chambers in the penis that are responsible for erections. Signs of this include:

  • Extreme pain
  • A noticeable ‘popping’ sound
  • Loss of erection
  • Swelling or bruising of the penis

A fractured penis requires immediate medical attention. Without treatment, a fracture may result in permanent damage.
