Not masturbating is not bad for you. There is no medical condition caused by abstaining from masturbation, and your body will naturally manage unused sperm and seminal fluid on its own, often through nocturnal emissions. That said, regular ejaculation does appear to offer some modest health benefits, and the decision to abstain can sometimes cause more psychological stress than the act itself, depending on why you’re avoiding it.
What Happens to Your Body When You Stop
If you stop masturbating, your body doesn’t stockpile anything dangerous. Sperm that aren’t ejaculated are broken down and reabsorbed. Seminal fluid follows the same recycling process. There’s no buildup of pressure or toxins, and nocturnal emissions (wet dreams) may occur more frequently as a natural release valve.
One hormonal change does occur in the short term. A small study found that testosterone levels spike to about 146% of baseline on the seventh day of abstinence. After that peak, levels don’t continue climbing. They settle back down without any regular pattern of fluctuation during continued abstinence. So the idea that avoiding ejaculation steadily builds testosterone over weeks or months isn’t supported by the data. You get a brief bump, then it fades.
The Prostate Cancer Connection
This is the one area where regular ejaculation shows a meaningful long-term benefit. A large study following men over several decades found that those who ejaculated 21 or more times per month had roughly a 20% lower risk of prostate cancer compared to men who ejaculated 4 to 7 times per month. That association held for men reporting their habits in their 20s and again in their 40s.
The working theory is that frequent ejaculation clears potentially harmful substances from the prostate before they can cause cellular damage. This doesn’t mean infrequent ejaculation causes prostate cancer, and the study measured all ejaculation (partnered sex included, not just masturbation). But it does suggest that long-term abstinence removes one factor that may be slightly protective.
Sleep and Stress Relief
Orgasm triggers a release of hormones that promote relaxation: oxytocin, prolactin, and endorphins, along with a drop in cortisol, the body’s primary stress hormone. This combination has a sedative-like effect that many people experience as drowsiness or calm after climax. One pilot study using objective sleep measurements found that both masturbation and partnered sex improved sleep efficiency and reduced nighttime wakefulness compared to nights with no sexual activity.
If you stop masturbating, you’re not losing access to sleep itself, obviously. But if masturbation was part of your wind-down routine, you may notice it takes a bit more effort to relax before bed. The effect is real but modest, and other relaxation techniques can fill the gap.
Fertility and Sperm Quality
If you’re trying to conceive, the relationship between abstinence and sperm quality is more nuanced than “save it up.” The World Health Organization recommends 2 to 7 days of abstinence before a semen analysis or fertility treatment. Longer abstinence increases sperm concentration (you produce a higher count per sample), but shorter abstinence periods improve motility, meaning the sperm that are there swim better and are more likely to reach an egg.
So complete abstinence for weeks doesn’t optimize fertility. It raises the total count but fills the sample with older, less mobile sperm. For couples trying to conceive naturally, ejaculating every 2 to 3 days tends to strike the best balance between volume and quality.
Immune Function
One study found that masturbation to orgasm temporarily increased the number of certain white blood cells in the bloodstream, particularly natural killer cells, which are part of your body’s first-line defense against infections. However, a separate analysis looking at immunoglobulin A (an antibody found in mucous membranes) found no significant relationship between masturbation frequency and antibody levels in either men or women. Partnered sex, by contrast, did show a positive association with immune markers, possibly because the body mounts a mild immune response to a partner’s microorganisms. The immune benefits of masturbation specifically are limited and inconsistent.
When the Guilt Does More Harm Than the Abstinence
For many people who search this question, the real issue isn’t physical at all. It’s psychological. Cultural and religious frameworks across many traditions treat masturbation as immoral, and that messaging can create intense guilt regardless of whether someone masturbates or abstains. In some cases, that guilt is more damaging than whatever behavior prompted it.
Clinical case reports have documented masturbation-related guilt contributing to severe depression, psychotic symptoms, and delusional beliefs about physical harm from the act. These are extreme outcomes, but milder versions of the same pattern are common: a persistent sense of shame, anxiety about being “broken,” or obsessive monitoring of whether your habits are normal. Some research has linked higher masturbation frequency with depressive symptoms and relationship dissatisfaction, but the direction of that relationship is unclear. People who are already depressed or lonely may masturbate more as a coping mechanism rather than the other way around.
If you’re abstaining because it aligns with your values and you feel good about the choice, there’s no health reason to override that. If you’re abstaining because you believe masturbation is physically harmful and the effort to resist causes you constant stress, that stress itself is likely the bigger problem.
When Masturbation Habits Become a Problem
The flip side of this question is worth addressing. Masturbation becomes a clinical concern not based on frequency alone, but based on control and consequences. The World Health Organization recognizes compulsive sexual behavior disorder, defined as a persistent failure to control sexual impulses over six months or more that causes significant distress or impairment. The key markers include: sexual behavior becoming the central focus of your life to the point of neglecting health or responsibilities, repeated unsuccessful attempts to cut back, continuing despite clear negative consequences like job loss or relationship damage, or continuing even when you get little or no satisfaction from it.
Importantly, the diagnostic guidelines explicitly state that a high sex drive alone, even one that causes some distress, does not qualify. Adolescents who masturbate frequently should not be diagnosed even when they feel embarrassed about it. The threshold is functional impairment, not frequency.
One Physical Risk Worth Knowing
Masturbation technique matters more than frequency for physical health. Prone masturbation, where a person lies face down and thrusts against a mattress or surface, can cause chronic overuse of pelvic floor muscles. Over time this leads to pelvic floor incoordination, which can contribute to bladder problems, bowel issues, and sexual dysfunction. This isn’t a risk of masturbation in general but of one specific technique that places unusual pressure on the pelvic region. Standard masturbation with a hand does not carry this risk.
