Masturbation is not bad for you. It’s a normal part of human sexuality with no evidence of physical harm when done in moderation. For most people, it offers modest health benefits, from better sleep to stress relief. The exceptions are narrow: habits that interfere with daily life, or techniques that reduce physical sensitivity over time. Here’s what the evidence actually shows.
What Happens in Your Body
Orgasm from masturbation triggers the same hormonal cascade as partnered sex. Your brain releases a burst of feel-good chemicals that produce relaxation and mild euphoria. One hormone in particular, prolactin, rises substantially after orgasm and stays elevated for over an hour in both men and women. Prolactin is thought to act as a natural “off switch” for sexual arousal, which is why you feel satisfied and calm afterward rather than immediately wanting more.
This hormonal response also explains why masturbation can help with sleep. A pilot study on sleep quality found that both solo masturbation and partnered sex significantly reduced wakefulness after falling asleep and improved sleep efficiency compared to nights with no sexual activity. Participants did fall asleep later on those nights (likely because of the time spent), but the quality of sleep itself was measurably better.
Potential Health Benefits
The most studied benefit is specific to men. A large Harvard-linked 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 4 to 7 times per month. A follow-up analysis found that men averaging about 5 to 7 ejaculations per week were 36% less likely to be diagnosed with prostate cancer before age 70. The mechanism isn’t fully understood, but the association is consistent across multiple studies.
For women, masturbation can help relieve menstrual cramps. The muscle contractions during orgasm increase blood flow to the pelvic area, which can ease cramping. Orgasm also strengthens the pelvic floor muscles over time, which supports bladder control and sexual function.
For both sexes, the stress-relief effect is real but straightforward: orgasm temporarily lowers tension and promotes relaxation. It’s not a treatment for anxiety or depression, but it can take the edge off a stressful day in the same way that exercise does.
Effects on Sexual Function
This is where the picture gets more nuanced, and relationship status matters. A study examining masturbation frequency and sexual function found that for single men, more frequent masturbation was associated with better erectile function. For men in relationships, the link disappeared. In fact, partnered men who masturbated more frequently reported worse orgasmic function and lower intercourse satisfaction. The same pattern appeared in women: single women who masturbated more often had better orgasmic function and sexual satisfaction, while partnered women who masturbated more showed the opposite trend.
This doesn’t mean masturbation damages sexual function. The researchers found that lower sexual compatibility and sexual problems in a partner were associated with more frequent masturbation in both men and women. In other words, people in unsatisfying sexual relationships masturbate more, not the other way around. Masturbation may be a symptom of relationship friction rather than a cause of it.
The “Death Grip” Problem
One physical concern has some basis in reality, though it’s not an official medical diagnosis. Frequently masturbating with an unusually tight grip or very specific technique can gradually reduce nerve sensitivity in the penis, making it harder to reach orgasm during partnered sex. This creates a cycle: as sensitivity drops, you grip harder, which reduces sensitivity further.
The fix is straightforward. Sexual health experts recommend taking a week-long break from all sexual stimulation, then gradually reintroducing masturbation over three weeks with a lighter touch and varied technique. Most people regain normal sensitivity within that timeframe.
Myths That Won’t Die
Masturbation does not cause hair loss. There are no studies connecting the two. The theory that ejaculation raises testosterone, which then raises the hair-loss hormone DHT, actually runs backward: research shows testosterone levels increase after abstaining from ejaculation for three weeks, not after ejaculating. Either way, there’s no evidence that masturbation affects DHT levels at all.
Masturbation also doesn’t cause infertility. According to the Mayo Clinic, frequent ejaculation is unlikely to have much effect on fertility. Some data suggests sperm quality is slightly better after two to three days without ejaculating, but men with normal sperm quality maintain normal concentrations and motility even with daily ejaculation. If you’re trying to conceive, having intercourse several times a week maximizes your chances regardless of how often you masturbate.
When It Becomes a Problem
The line between healthy and problematic isn’t about frequency. There’s no magic number of times per week that crosses into “too much.” The concern is about control and consequences. Compulsive sexual behavior disorder, recognized in the international classification of diseases, is defined by a persistent inability to control sexual impulses over six months or more, to the point where the behavior causes significant problems in your relationships, work, health, or daily responsibilities.
Key signs include sexual activity becoming the central focus of your life at the expense of other interests, multiple failed attempts to cut back, and continuing despite negative consequences or getting little satisfaction from it. This is rare, and it looks very different from someone who simply masturbates often.
One important distinction: feeling guilty about masturbation because of moral or religious beliefs does not qualify as a disorder. The diagnostic criteria explicitly state that distress entirely related to moral judgments about sexual behavior is not sufficient for diagnosis. Guilt and shame rooted in cultural messaging can cause real psychological distress, but the solution there is addressing the belief system or finding support, not pathologizing the behavior itself.
The Bottom Line on Frequency
There is no established “right” amount. If masturbation fits comfortably into your life, doesn’t interfere with your responsibilities or relationships, and isn’t causing physical irritation from overly aggressive technique, it’s not harming you. For most people, it’s a minor net positive: a bit of stress relief, slightly better sleep, and for men, a potentially meaningful reduction in prostate cancer risk over a lifetime.
