Masturbation is not bad for you. It’s a normal part of human sexuality that most people engage in at some point, and the medical consensus is that it carries real health benefits with very few risks. The problems that do arise tend to come from how often or how aggressively someone does it, not from the act itself. Much of the shame surrounding masturbation comes from cultural or moral beliefs rather than anything happening in your body.
Physical Health Benefits
Orgasm triggers a short-term boost in your immune system. A study measuring blood markers after sexual arousal and orgasm found that the number of natural killer cells, a key part of your body’s first-line defense against infections, increased in the bloodstream. Other immune cell types like T cells and B cells stayed the same, suggesting the effect is specific to the innate immune response.
There’s also a notable connection to prostate health. A large, long-running study followed tens of thousands of men and found that those who ejaculated 21 or more times per month had about a 20% lower risk of prostate cancer compared to men who ejaculated 4 to 7 times per month. When looking at men in middle age specifically, the risk reduction was as high as 50%. This doesn’t prove ejaculation prevents cancer, but the correlation is strong and has held up over decades of follow-up data.
Stress, Sleep, and Mood
Masturbation reliably reduces stress and improves mood. Research on how people use masturbation in daily life found that it functions as a genuine coping and self-care strategy, producing feelings of happiness, relaxation, and a sense of control. People consistently report using it to manage anxiety, lift depressive moods, and fall asleep more easily. The relaxation effect appears to be especially pronounced with certain types of stimulation. One set of findings suggested that orgasms from different types of stimulation may have slightly different emotional effects: some feel more energizing, others more calming.
What Happens to Testosterone
A common concern is that ejaculation drains testosterone. The reality is more nuanced. A study tracking testosterone levels daily during abstinence found that levels barely changed from day 2 through day 5 after ejaculation. On day 7, testosterone spiked to about 145% of baseline, a statistically significant peak. After that spike, levels didn’t follow any regular pattern and settled back down. So ejaculation causes a brief, predictable hormonal cycle rather than a lasting drop. Your baseline testosterone isn’t lowered by regular masturbation.
When Habits Affect Sexual Performance
One area where masturbation can genuinely cause problems is partnered sex, specifically when it comes to reaching orgasm with a partner. Clinicians have identified three masturbation-related factors linked to delayed ejaculation: frequency greater than three times per week, an unusual technique, and a gap between the fantasies used during masturbation and what actually happens during sex with a partner.
The technique issue is the most significant. Some men develop what’s called an idiosyncratic masturbatory style, meaning they rely on a specific combination of speed, pressure, duration, body position, or focus on a particular spot that a partner simply can’t replicate. Over time, this can make it difficult or impossible to climax during partnered sex. Some men even develop skin irritation or redness from how aggressively they masturbate. The fix is straightforward in concept: vary your technique, use your non-dominant hand, and try to approximate the kind of stimulation you’d experience with a partner.
Physical Risks of Excess
For the vast majority of people, there are no physical side effects. But at extreme frequencies sustained over long periods, problems can develop. Case reports document chronic penile swelling caused by compulsive masturbation, where repeated friction led to persistent edema and thickened skin on the shaft. There’s also a condition called traumatic masturbatory syndrome, linked specifically to prone masturbation (face-down against a mattress). One documented case involved someone who masturbated 4 to 5 times daily for 20 years in this position, leading to chronic overuse of the pelvic floor muscles. That overuse caused the muscles to become hypertonic (too tight) and uncoordinated, resulting in bladder and bowel problems alongside sexual dysfunction.
These are extreme cases. They illustrate that physical harm is possible but requires patterns far outside what most people would consider normal.
Guilt Does More Harm Than the Act
Perhaps the most important thing to understand is that guilt about masturbation often causes more psychological damage than masturbation itself. Research has found that people who feel intense guilt about masturbating are more likely to experience depressive symptoms, dissatisfaction with their mental health, and even somatization, where emotional distress manifests as physical symptoms. In clinical case studies, masturbatory guilt appeared as both a symptom of depression and a trigger for depressive episodes. In one case, it was intertwined with psychotic symptoms.
The guilt itself tends to come from cultural or religious beliefs rather than from any signal your body is sending you. The ICD-11, the international system used to classify health conditions, explicitly states that distress caused by moral judgments about sexual behavior does not, on its own, qualify as a disorder. Feeling bad about masturbating because you were taught it’s wrong is not the same as having a problem with masturbation.
When It Actually Becomes a Problem
There is a recognized condition called compulsive sexual behavior disorder, included in the ICD-11. It’s defined by a persistent inability to control sexual urges over six months or more, leading to real impairment in your life. The diagnostic criteria are specific: sexual activity has become the central focus of your life to the point where you’re neglecting your health, responsibilities, or relationships. You’ve repeatedly tried to cut back and failed. You keep doing it despite clear negative consequences. Or you continue even though it no longer brings satisfaction.
Crucially, a high sex drive alone doesn’t meet the criteria. Someone who masturbates frequently but isn’t experiencing distress or life impairment does not have this disorder. The guidelines also specifically note that frequent masturbation among adolescents is normal, even when the person feels some distress about it. The line between healthy and compulsive isn’t about frequency. It’s about whether you’ve lost control and whether your life is suffering because of it.
