Not masturbating is not harmful. Your body has no strict requirement for ejaculation, and there is no medical condition caused solely by abstaining. That said, regular ejaculation does appear to offer some measurable health benefits, particularly for prostate health and sperm quality. Whether abstaining is the right choice for you depends on your reasons and how your body responds.
What Happens to Your Body When You Stop
If you stop ejaculating entirely, your body doesn’t just stockpile indefinitely. Older sperm cells are broken down and reabsorbed, and your body may release excess through nocturnal emissions (wet dreams). Adults of any age can experience wet dreams, and they become more common when you’re not having sex or masturbating regularly. The frequency varies widely from person to person. Some men experience them often, others rarely or never.
Testosterone levels follow an interesting short-term pattern during abstinence. A study on ejaculation and serum testosterone found that levels remained stable for the first six days of abstinence, then spiked to about 145% of baseline on day seven before returning to normal. This is often cited in online communities promoting abstinence, but it’s a temporary peak, not a sustained increase. Long-term abstinence does not appear to raise your baseline testosterone in any lasting way.
The Prostate Cancer Connection
The strongest argument for regular ejaculation comes from prostate cancer research. A large Harvard-linked study tracking tens of thousands of men found that those 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. An Australian study found a similar pattern: men averaging about 5 to 7 ejaculations per week were 36% less likely to be diagnosed with prostate cancer before age 70 than men who ejaculated fewer than about twice a week.
These are observational studies, meaning they show a correlation rather than definitive proof that ejaculation itself prevents cancer. Other lifestyle factors could play a role. Still, the association is consistent across multiple large studies, and the size of the risk reduction is notable. No major medical organization has issued a specific ejaculation target based on this data, but the pattern is hard to ignore.
Sperm Quality and Fertility
If you’re trying to conceive or planning to in the future, abstinence duration matters for sperm quality. The World Health Organization recommends 2 to 7 days of abstinence before providing a semen sample, as this window tends to produce the best balance of volume and concentration. But longer abstinence isn’t better.
A systematic review in the World Journal of Men’s Health found that shorter abstinence periods (two days or fewer) produced peak sperm motility, which is the ability of sperm to swim effectively. Longer abstinence increased semen volume and sperm concentration, but it also increased DNA fragmentation, a form of genetic damage in sperm cells that can reduce fertility and increase miscarriage risk. In men with low sperm counts, shorter abstinence periods actually improved the percentage of normally shaped sperm while reducing DNA damage.
In practical terms: if fertility is a priority, ejaculating every two to three days keeps your sperm in better shape than holding off for weeks at a time.
Pelvic Floor Effects Worth Knowing
One area where the relationship is more nuanced involves pelvic floor muscles, the group of muscles that support your bladder, bowel, and sexual function. Masturbation itself isn’t harmful to these muscles, but certain habits can cause problems over time. Many men unconsciously clench their pelvic floor muscles as they approach orgasm, and repeated tightening without relaxation can lead to chronic muscle tension. Very high frequency, combined with these tensing habits, can contribute to muscle fatigue.
Symptoms of a tight pelvic floor include persistent dull or sharp pain in the pelvic region, lower back, or genital area. Some men develop painful ejaculation or symptoms that mimic prostatitis, like discomfort during urination or sexual activity. These issues aren’t caused by masturbation per se but by the physical tension patterns that sometimes accompany it. Taking a break from masturbation can actually help if you’re dealing with pelvic floor tightness, giving those muscles time to relax and recover.
Mental Health and Personal Reasons
Many people who search this question are really asking whether they should stop because masturbation feels compulsive, takes up too much time, or conflicts with personal values. Those are all valid reasons to take a break or stop entirely, and doing so won’t cause physical harm.
Some men report improved focus, motivation, or emotional clarity during periods of abstinence. These experiences are real for the people having them, though controlled studies haven’t confirmed a consistent biological mechanism beyond the temporary testosterone spike on day seven. The psychological benefits of feeling in control of a habit can be significant on their own, regardless of what’s happening hormonally.
On the other hand, masturbation serves as a natural stress reliever and sleep aid for many people. Orgasm triggers a release of hormones that promote relaxation and drowsiness. Giving that up may mean finding other ways to manage stress or wind down at night.
The Bottom Line on Frequency
There is no medical organization that defines a required number of ejaculations per week or month. Your body can handle abstinence without breaking down, and it can handle frequent ejaculation without wearing out. The health data leans slightly in favor of regular ejaculation for long-term prostate health and sperm quality, but “regular” is a wide range. The research showing the clearest benefits compares extremes: very infrequent (a few times a month) versus very frequent (several times a week).
If you feel better not masturbating, whether for psychological, spiritual, or personal reasons, the physical tradeoffs are modest. If you’re experiencing pelvic pain or discomfort, a temporary break may help. If you’re trying to conceive, don’t abstain for more than a few days at a time. And if you have no particular reason to stop, the existing evidence suggests that regular ejaculation is a net positive for your body.
