Most men masturbate, and most do so regularly. In a nationally representative British survey, about 73% of men reported masturbating within the previous four weeks, a figure that dwarfs the roughly 37% of women who said the same.1PubMed. Prevalence of masturbation and associated factors in a British national probability survey But “how often” varies enormously by age, relationship status, health, and even how the question is asked, and the data on this topic is messier than most summaries let on.
What the Population-Level Numbers Look Like
Large surveys consistently find that a clear majority of men have masturbated recently. The British probability survey cited above, which drew from thousands of respondents, found that nearly three in four men had masturbated in the past month. A U.S. nationally representative survey conducted during the COVID-19 pandemic echoed that general picture, with men’s masturbation frequency closely tracking how much they wished they were having more partnered sex: men who wanted much more partnered sex were over four times as likely to report frequent masturbation as men satisfied with their current sex lives.2PubMed Central. Masturbation Prevalence, Frequency, Reasons, and Associations with Partnered Sex in the Midst of the COVID-19 Pandemic
What these numbers don’t tell you is a single “normal” frequency. Some men masturbate daily; others a few times a month; a meaningful minority not at all. Surveys tend to report prevalence (whether someone masturbated at all in a time window) rather than exact weekly tallies, partly because frequency is so variable week to week that a snapshot number can be misleading. The honest answer to “how often” is that most men fall somewhere between a few times a week and a few times a month, with wide tails on both ends.
How Age Shapes the Pattern
Masturbation frequency follows a loose arc across the lifespan, peaking in adolescence and early adulthood before tapering gradually. Among U.S. adolescent males, a national study found that about 43% of 14-year-olds had masturbated in the past month, rising to about 68% of 17-year-olds.3Archives of Pediatrics & Adolescent Medicine. Prevalence, Frequency, and Associations of Masturbation With Partnered Sexual Behaviors Among US Adolescents By the late teens, roughly four in five boys had ever masturbated. That trajectory steepens into the twenties and thirties, when surveys typically record the highest frequencies.
At the other end, masturbation persists well into later life but becomes less common and less frequent. A study of older adults across four European countries found that age, education, self-perceived health, and depression all predicted whether men reported masturbating, though the same factors were less predictive for women.4PubMed Central. Prevalence of Masturbation and Associated Factors Among Older Adults in Four European Countries In other words, declining health and mood seem to suppress masturbation in men more than in women, though plenty of healthy older men continue the behavior.
Looking across generations rather than age groups, the trend is clearly upward. A comparison of five generational cohorts of American men found that solitary masturbation “rose somewhat spectacularly in significance with the passing decades,” even as other sexual outlets like nocturnal emissions declined.5PubMed. Intergenerational change in sex behavior: a belated look at Kinsey’s males Greater social openness around masturbation and easier access to erotic material likely explain part of that shift, though changes in how willing men are to report the behavior probably matter too.
Relationship Status and Partnered Sex
A common assumption is that men who have regular partners masturbate less. The reality is more complicated. Men in relationships do masturbate, sometimes frequently, and the research suggests a “compensatory” pattern: when partnered sex is less available or less frequent than desired, masturbation fills the gap. This contrasts with a “complementary” pattern observed more often in women, where masturbation tends to increase alongside partnered sexual activity rather than substitute for it.6PubMed Central. A Seemingly Paradoxical Relationship Between Masturbation Frequency and Sexual Satisfaction
The COVID-era U.S. survey sharpened this finding. Men who wanted much more partnered sex than they were getting were roughly 4.4 times more likely to report high masturbation frequencies compared to men who felt their partnered sex life was about right.2PubMed Central. Masturbation Prevalence, Frequency, Reasons, and Associations with Partnered Sex in the Midst of the COVID-19 Pandemic Even men who desired only slightly more partnered sex were about 2.4 times more likely to masturbate frequently. So relationship status alone is a poor predictor. The mismatch between desired and actual partnered sex matters far more.
Why Men Say They Do It
When researchers ask men directly, the reasons cluster around a few themes. Pleasure ranks first, followed by reducing sexual tension and relieving anxiety or stress.7PubMed. Why Men Masturbate: Reasons and Correlates in Men with and without Sexual Dysfunction Partner-related issues like relationship dissatisfaction rank lower on the list, which may surprise people who assume frequent masturbation signals a problem with a partner. Men with sexual difficulties cited stress and anxiety reduction somewhat more often than men without, but otherwise the motivational profiles looked similar.
A systematic review examining masturbation in long-distance relationships found a consistent gender difference in motivation: men were primarily driven by biological release, orgasm, and stress reduction, and often used pornography in the process. Women reported a broader range of motivations including relaxation, sleep improvement, and emotional closeness.8The Journal of Sexual Medicine. Masturbation as a sexual and psychological coping strategy in long-distance relationships: a systematic review The takeaway is that for most men, masturbation serves a functional role that goes beyond simple horniness, though sexual desire is still the primary engine.
The Reliability Problem with Self-Reported Frequency
Every number in this article comes with an asterisk: all of it is self-reported, and self-reports about masturbation are unreliable in specific, predictable ways. A study comparing daily diaries to later questionnaire recall found that masturbation frequency is systematically overestimated when people try to remember it after the fact.9PubMed. Parallel accounts? Discrepancies between self-report (diary) and recall (questionnaire) measures of the same sexual behaviour In other words, when men fill out a survey asking how often they masturbated last month, they tend to report higher numbers than their own daily logs would suggest.
A separate study found that men specifically overestimate the frequency of both sexual interest and masturbation when recalling a 30-day window, and that their current mood biases the recall: feeling good tends to inflate the numbers, feeling bad deflates them.10The Journal of Sexual Medicine. Accuracy of 30‐Day Recall for Components of Sexual Function and the Moderating Effects of Gender and Mood This does not mean the broad patterns in the data are wrong. It means the specific numbers should be held loosely. When a survey says “X% of men masturbated in the past month,” the real number is probably somewhat lower, and the “how many times per week” estimates are probably inflated by a bit.
What Happens Hormonally
A persistent internet claim is that masturbation lowers testosterone. The evidence does not support this in any meaningful way. A small randomized crossover study in healthy young men found that masturbation appeared to counteract the natural drop in free testosterone that occurs over the course of a day, but the ratios between total testosterone, free testosterone, and cortisol did not significantly change.11PubMed Central. Hormonal response after masturbation in young healthy men – a randomized controlled cross-over pilot study And an older but well-cited study found that natural differences in testosterone levels among men within the normal range did not correlate with differences in sexual activity or interest at all.12PubMed. Serum testosterone and sexual activity and interest in men The idea that frequent masturbation meaningfully depletes testosterone is not backed by the data.
What does happen after orgasm is a spike in prolactin, a hormone linked to the feeling of satiety and reduced arousal. Prolactin levels stay elevated for over an hour following orgasm, whether from masturbation or intercourse.13PubMed. Orgasm-induced prolactin secretion: feedback control of sexual drive? However, the prolactin surge after intercourse is about four times larger than the surge after masturbation, which researchers interpret as intercourse producing greater physiological satisfaction.14PubMed. The post-orgasmic prolactin increase following intercourse is greater than following masturbation and suggests greater satiety This probably explains why masturbation sometimes feels less “complete” than sex with a partner, and why the refractory period after intercourse tends to feel longer. The prolactin difference may also be part of why intercourse, more than masturbation, tends to help with sleep.
Ejaculation Frequency and Prostate Cancer Risk
One of the most commonly cited health links to masturbation involves prostate cancer. A large prospective study following tens of thousands of men over nearly two decades found that men who ejaculated 21 or more times per month had roughly a 20% lower risk of prostate cancer compared to men who ejaculated four to seven times per month, whether measured at ages 20-29 or 40-49.15PubMed Central. Ejaculation Frequency and Risk of Prostate Cancer: Updated Results with an Additional Decade of Follow-up The association was strongest for low-risk disease and held up even after accounting for screening patterns.
An updated meta-analysis looking at multiple studies broadly confirmed that higher ejaculation frequency was protective, with a pooled estimate showing about a 17% risk reduction for higher-frequency ejaculators.16PubMed Central. Updated dose-response meta-analysis of sexual activity and prostate cancer risk But there is an important distinction: that protective association was with ejaculation frequency overall, not specifically with masturbation. When the meta-analysis isolated masturbation frequency on its own, the association with prostate cancer was positive but not statistically significant. In plain language, ejaculating often seems to help, but the data does not clearly show that masturbation specifically is what drives the benefit versus intercourse or other sexual activity. Researchers suspect the mechanism involves flushing out carcinogenic secretions, reducing prostatic stasis, or lowering intraprostatic pressure, but none of this is proven.
Masturbation and Erectile Function
Another anxiety-driven question, particularly among younger men, is whether frequent masturbation causes erectile difficulties. An international web-based survey of young men found that masturbation frequency was not a significant factor when assessing erectile dysfunction.17JMIR Publications. Associations Between Online Pornography Consumption and Sexual Dysfunction in Young Men The concern usually gets tangled with pornography use, which the same study did examine as a separate variable. But the physical act of masturbating, at typical frequencies, does not appear to impair erectile function on its own.
Where masturbation can become clinically relevant is not in its frequency but its style. Sex therapists working with men who have delayed ejaculation often find that an idiosyncratic masturbation technique, meaning a grip, pressure, or speed that a partner’s body cannot replicate, contributes to the problem. Treatment sometimes involves altering the technique or switching hands so the man’s arousal pattern becomes more compatible with partnered sex.18PubMed Central. Psychosexual therapy for delayed ejaculation based on the Sexual Tipping Point model This is about how, not how often.
When Masturbation Feels Like a Problem
There is no clinical threshold that makes a certain number of times per week “too much.” Instead, clinicians look at distress and functional impairment. A large study examining the gap between men’s actual and desired masturbation frequency found that about 8% of men experienced what the researchers defined as self-perceived problematic masturbation, meaning they masturbated more than they wanted to and felt distressed about it.19SpringerLink / Archives of Sexual Behavior. Actual and Desired Masturbation Frequency, Sexual Distress, and Their Correlates When the definition was tightened to include only those who also masturbated more frequently than average, the proportion dropped to about 2%. And interestingly, about 6% of men masturbated less often than average yet still felt their masturbation was problematic, suggesting that distress about the behavior is not always driven by high frequency.
This is a useful corrective to the narrative that frequent masturbation equals compulsive behavior. For most men who masturbate often, the behavior is not distressing. For a smaller group, it is, and those men may benefit from professional support. But the distress is the clinical signal, not the number on a tally sheet.
Guilt, Culture, and Religion
Cultural and religious context profoundly shapes how men feel about masturbation, even when it does not change how often they do it. A study of married Chinese men in a clinical setting found weak but significant positive correlations between masturbation-related guilt and scores on standard measures of anxiety and depression.20PubMed Central. Prevalence of masturbation and masturbation guilt and associations with partnered sex among married heterosexual Chinese males Men who felt a very strong sense of guilt had a negative association with partnered sex frequency, suggesting that intense shame may spill over into their sexual relationships.
Among religious Jewish single men, the picture was counterintuitive. Sexual guilt and shame were linked to worse psychological well-being at low levels of religiousness, but at high levels of religiousness, that link disappeared.21PubMed. The Moderating Effect of Religiousness on the Relation Between Sexual Guilt and Shame and Well-Being Among Jewish Religious Single Men The researchers suggested that strong religious frameworks may provide coping mechanisms, community support, or meaning-making structures that buffer against the psychological toll of guilt. The implication is not that guilt is harmless, but that its effects depend heavily on the social ecosystem around it.
Semen Quality and Fertility Timing
Men trying to conceive sometimes worry about whether frequent ejaculation drains their sperm reserves. A study that tracked semen samples over repeated daily ejaculations found that sperm density dropped significantly between the first and third samples (from roughly 64 million per milliliter to about 52 million), but motility and morphology, two measures of sperm quality that matter for fertilization, did not change.22PubMed Central. Effect of repeated semen ejaculation on sperm quality So frequent ejaculation does reduce the sheer number of sperm per sample, but the sperm that show up are still moving and shaped normally. For most men, a day or two of abstinence before timed intercourse is sufficient to bring counts back up. The old advice of prolonged abstinence before trying to conceive has largely fallen out of favor, since excessively long gaps between ejaculations can increase the proportion of damaged sperm.
Devices, Vibrators, and How Technology Has Changed the Picture
Masturbation technology is no longer a fringe topic. A nationally representative U.S. survey found that about 45% of men had used a vibrator in sexual activity at some point in their lives, with about 10% having done so in the past month.23PubMed Central. Prevalence and characteristics of vibrator use by men in the United States Men who had used vibrators recently scored higher on measures of erectile function, intercourse satisfaction, orgasmic function, and sexual desire. They were also more likely to have performed testicular self-exams, a basic sexual-health screening behavior. The researchers interpreted this less as vibrators directly boosting function and more as an indicator that men comfortable exploring their sexuality tend to be more attentive to their sexual health overall.
The market for male masturbation devices has expanded dramatically in recent years, from simple sleeves to app-connected devices marketed as “sexual wellness tools.” Whether these devices change frequency patterns at a population level is unknown, but they do shift the conversation around male masturbation toward the language of health and self-care rather than secrecy and shame, a cultural shift that parallels the normalization of vibrator use among women a generation earlier.
An Evolutionary Footnote
A question researchers have puzzled over is why masturbation exists at all from an evolutionary standpoint, since it seems to waste reproductive resources. A large comparative study across nearly 300 primate species found strong evidence that masturbation in males coevolved with both mating systems and pathogen exposure.24PubMed Central. The evolution of masturbation is associated with postcopulatory selection and pathogen avoidance in primates Two hypotheses were supported. First, masturbation may help males in competitive mating systems by clearing older, less motile sperm before copulation, improving sperm quality when it counts. Second, masturbation may flush the urethra of pathogens picked up during prior sexual encounters, reducing infection risk. Neither hypothesis was supported in female primates, suggesting the evolutionary pressures driving the behavior differ by sex. None of this is directly relevant to a man deciding whether his habits are healthy, but it does undercut the notion that masturbation is a dysfunction or aberration. It has been part of the primate toolkit for a very long time.
