The vast majority of men masturbate. A nationally representative U.S. survey of nearly 3,000 men ages 14 to 94 found that roughly 92% of men in their 20s through 40s have masturbated at some point in their lives, and about 60–69% of men in that same range did so in the past month alone.
Lifetime and Recent Numbers
The National Survey of Sexual Health and Behavior, one of the largest probability-based sex surveys in the U.S., breaks the numbers down clearly. By their early 20s, about 92% of men report having masturbated at least once. That figure stays remarkably stable through middle age, hovering between 89% and 94% for men in their 20s, 30s, 40s, and 50s. Even among men over 70, roughly 80% say they’ve done it.
Looking at the past year narrows the picture a bit. Around 83% of men in their mid-20s to late 20s masturbated in the previous 12 months. That drops gradually with age: about 76% of men in their 40s, 72% in their 50s, 61% in their 60s, and 46% of men 70 and older. For teens just entering puberty (ages 14–15), the past-year figure sits at about 62%, climbing to around 75% by ages 16–17.
How Often Men Masturbate
Among men ages 18 to 59, about a quarter masturbate a few times per month to once a week. Roughly 20% do it two to three times per week, and fewer than 20% report four or more times a week. The most common pattern for adult men lands somewhere in the range of a few times a month.
Frequency peaks in the late 20s and early 30s and tapers off with age, but the decline is gradual rather than sharp. Around 67% of men in their 30s and 60% of men in their 40s still masturbated in the past month. For adolescents and men over 70, masturbation is actually more common than partnered sex, making it the primary form of sexual activity at both ends of the age spectrum.
Rates Are Climbing Over Time
Men aren’t just maintaining these numbers; they’re reporting more masturbation than in previous decades. British national sex surveys conducted roughly a decade apart found that the percentage of men who masturbated in the past month rose from 73.4% to 77.5% between the early 2000s and 2010–2012. Researchers at the Kinsey Institute noted this was a statistically significant increase. Greater access to internet pornography and reduced stigma around solo sex are commonly cited factors, though the surveys measured behavior, not motivation.
Effects on Sleep and Stress
Masturbation that ends in orgasm triggers a hormonal cascade that most people experience as relaxation and drowsiness. The body releases oxytocin (which lowers cortisol, the primary stress hormone) and prolactin (linked to sexual satisfaction and sleepiness). A pilot study on sleep outcomes found that both solo masturbation and partnered sex with orgasm shortened the time it took to fall asleep, reduced nighttime wakefulness, and improved overall sleep efficiency compared to nights with no sexual activity.
The Prostate Connection
One of the more striking findings in men’s health research ties ejaculation frequency to prostate cancer risk. A large Harvard-based study found that men who ejaculated 21 or more times per month had a 31% lower risk of prostate cancer compared to men who ejaculated four to seven times per month. The study tracked men over many years and counted all ejaculations, whether from sex, masturbation, or nocturnal emissions. This doesn’t prove masturbation prevents cancer, but the association is strong enough that researchers have consistently flagged it.
When Masturbation Becomes a Problem
There’s no clinical threshold for “too much” masturbation based on frequency alone. The concern isn’t how often someone does it but whether it causes distress or interferes with daily life. The World Health Organization recognizes compulsive sexual behavior disorder as an impulse control condition in its international diagnostic system. The hallmarks are repeated failure to control sexual urges, continuing the behavior despite it causing harm to relationships or responsibilities, and significant personal distress about the pattern. Most men who masturbate regularly, even daily, don’t come close to meeting these criteria.
If masturbation is replacing things you want to be doing, causing physical irritation, or creating anxiety and guilt that disrupts your day, that pattern is worth paying attention to. The behavior itself isn’t the issue; the relationship to it is.
