Most men between 18 and 59 masturbate somewhere between a few times per month and a few times per week. About a quarter fall in the “few times per month to weekly” range, roughly 20% do so two to three times per week, and fewer than 20% masturbate more than four times a week. There’s no single “normal” number, and frequency varies widely depending on age, relationship status, stress levels, and sex drive.
Frequency by Age
Younger men tend to masturbate more often than older men. Among men 18 to 59, the most common pattern is a few times per month to once a week, but a significant portion falls on either side of that range. Older men are more likely to report no masturbation at all over the previous year. This tracks with the natural decline in testosterone and libido that happens with aging, though plenty of men stay sexually active well into later life.
Relationship status also plays a role, but not always in the direction people assume. Men in relationships don’t necessarily masturbate less. For many, masturbation exists alongside partnered sex rather than as a substitute for it.
What Happens in Your Body
During masturbation, your brain releases dopamine, endorphins, and oxytocin, the same chemicals involved in feelings of pleasure, calm, and bonding. Testosterone rises during arousal and peaks at ejaculation, then returns to baseline within about 10 minutes. There’s no evidence that masturbation lowers testosterone levels over the long term.
You may have heard that abstaining from ejaculation builds testosterone or improves athletic performance. The science behind this is thin. While testosterone does fluctuate slightly with sexual activity, masturbation and ejaculation have not been shown to cause any lasting negative effects on hormone levels.
Effects on Mood and Sleep
A 2021 review found that masturbation helped reduce feelings of anxiety in men, likely because the combination of dopamine, oxytocin, and endorphins creates a temporary but real sense of relief. Oxytocin in particular helps lower cortisol, the body’s primary stress hormone.
Falling asleep more easily is one of the most commonly reported reasons people masturbate. The relaxation effect from oxytocin and endorphins makes this intuitive, though the research is mixed. A 2021 study found that masturbation before bed didn’t objectively improve sleep quality, even though participants believed it did. Whether placebo or physiology, many men find it a reliable part of their nighttime routine.
Prostate Health
One of the more striking findings in this area comes from a large Harvard-affiliated study. 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. A separate analysis from the same research found that men averaging about five to seven ejaculations per week were 36% less likely to be diagnosed with prostate cancer before age 70 than men who ejaculated fewer than two to three times per week.
These studies measured total ejaculation frequency, not just masturbation, so partnered sex counts too. The underlying mechanism isn’t fully understood, but the correlation is consistent enough that researchers take it seriously.
Fertility and Sperm Quality
If you’re trying to conceive, you might wonder whether frequent masturbation depletes your sperm. According to the Mayo Clinic, frequent masturbation isn’t likely to have much effect on fertility. Some data suggests that sperm quality peaks after two to three days without ejaculation, but other research shows that men with normal sperm quality maintain healthy sperm counts and motility even with daily ejaculation.
The practical takeaway: having sex several times a week will maximize your chances of conception whether you masturbate in between or not. You don’t need to “save up.”
When Frequency Becomes a Problem
There’s no specific number of times per week that crosses into unhealthy territory. The concern isn’t frequency itself but whether the behavior is causing problems in your life. The Mayo Clinic identifies compulsive sexual behavior not by how often it happens but by how it affects you. Signs include feeling unable to control the urge, using masturbation as your primary way to cope with loneliness or anxiety, continuing despite negative consequences like missing work or damaging relationships, and feeling persistent guilt or regret afterward.
Two useful questions to ask yourself: Can you manage the impulse when you need to? And is the behavior causing you genuine distress? If the answers are yes and no, respectively, your frequency is almost certainly fine. If you’re struggling with control or the habit is interfering with daily life, that’s worth exploring with a professional, not because masturbation is inherently harmful, but because compulsive patterns of any kind can signal underlying issues like depression or anxiety.
