Is Masturbation Good for You? What the Research Actually Says

Masturbation is one of the most common sexual behaviors there is, yet reliable information about its health effects is surprisingly hard to find. Some websites promise it will cure insomnia and prevent cancer. Others warn it will drain your energy. This guide looks at what peer-reviewed studies and major medical centers actually say, how strong that evidence is, and where the science still has gaps.

The short answer: normal, healthy, and low-risk

Cleveland Clinic, a large US academic medical center, describes masturbation as "a normal, healthy part of your sexual development" and says it is common among people of all sexes and ages (Cleveland Clinic, 2022). It also notes that masturbation has no serious side effects, carries no risk of pregnancy, and rarely spreads sexually transmitted infections, as long as any toys are cleaned after use.

That is an important starting point. Much of the anxiety people feel about masturbation comes from old myths, not from medical findings. We cover those myths in a separate article. Here, the focus is on the other side of the question: does masturbation actually do anything good for your health?

What medical sources list as possible benefits

Cleveland Clinic lists several benefits that studies have linked to masturbation. According to its overview, masturbation may:

The same page explains that orgasm releases dopamine and oxytocin, hormones associated with positive feelings, and that these work against cortisol, often called the stress hormone (Cleveland Clinic, 2022).

It is worth being honest about what this list is. It is a summary from a respected medical center, written for the public. It is not a guarantee that every person will experience every effect. The quality of evidence behind each item varies a lot. Some claims rest on large long-term studies. Others rest on surveys in which people describe how they feel. The table below sorts them out.

Summary of the article's evidence table (Cleveland Clinic 2022; Rider et al. 2016; Lastella et al. 2019; Fischer et al. 2021).

Prostate cancer: the strongest data, read carefully

The most-cited finding in this area comes from the Health Professionals Follow-up Study, a long-running Harvard-based study of US men working in health professions. Researchers analyzed 31,925 men who reported their average monthly ejaculation frequency on a 1992 questionnaire and followed them through 2010. During that time, 3,839 men were diagnosed with prostate cancer (Rider et al., 2016).

The results: men who reported 21 or more ejaculations a month had a lower risk of being diagnosed with prostate cancer than men who reported 4 to 7 a month. The hazard ratio was 0.81 for frequency in their twenties and 0.78 for frequency in their forties. In plain terms, roughly a 20% lower rate of diagnosis.

Before reading too much into that, consider what the study could and could not show:

On the other hand, the researchers did check some obvious alternative explanations. PSA screening and biopsy rates were similar across frequency groups, and the association held when they looked only at screened men. So the finding is real and interesting, but it is not a reason to change your habits for cancer prevention. Regular check-ups and talking to a doctor about screening remain the evidence-based steps.

Sleep: what people report

Many people say they fall asleep more easily after orgasm. Researchers at Central Queensland University in Australia surveyed 778 adults (442 women and 336 men, average age about 34) about sexual activity before sleep. Participants reported that orgasm, including orgasm through masturbation, was followed by better sleep quality and falling asleep faster, with no meaningful difference between men and women (Lastella et al., 2019).

The key word is perceived. This was an anonymous online survey of volunteers. It did not measure sleep with equipment, and it did not compare nights with and without orgasm in a controlled way. The authors themselves describe the findings as perceptions. So if you find masturbation helps you unwind at night, that is consistent with what many people report. It is not a proven sleep treatment, and it should not replace care for ongoing insomnia.

Stress, mood, and pain

The stress and mood claims rest mainly on what we know about the hormones released during sexual arousal and orgasm. Cleveland Clinic points to dopamine and oxytocin, and to their counterbalancing effect on cortisol (Cleveland Clinic, 2022). This is a reasonable explanation for why many people feel calmer afterward.

What is missing is strong clinical trial evidence that masturbation, specifically, reduces anxiety or depression over time. Cleveland Clinic also mentions possible relief from menstrual cramps and other aches. Again, this is plausible and harmless to try, but the research base is thin. A fair summary: masturbation is a low-risk way many people relax, not a substitute for treatment of a mental health condition or chronic pain.

Self-knowledge and partnered sex

One of the more practical benefits is learning how your own body responds. Cleveland Clinic notes that women who masturbate are more likely to experience orgasm with partners, and that in older people masturbation may be associated with less vaginal dryness and less pain during intercourse (Cleveland Clinic, 2022).

A common worry is that masturbating means something is wrong in a relationship. A large US study of 7,648 men and 8,090 women aged 18 to 60 found the picture is more complicated. For men, masturbation showed a modest tendency to make up for less frequent sex. For women, it tended to go along with more partnered sex. For both, being in a relationship and feeling content with one's sex life predicted masturbation more clearly than how often a person had sex (Regnerus et al., 2017). In other words, people with partners masturbate too, and that is ordinary.

Later life

Masturbation does not stop being relevant with age. A probability-based survey of 3,816 adults aged 60 to 75 in four European countries found that, depending on the country, 41% to 65% of men and 27% to 40% of women had masturbated in the past month. Satisfaction with one's sexual activity was among the factors linked to masturbation in almost all countries and in both men and women (Fischer et al., 2021). This does not prove masturbation causes satisfaction, but it shows that solo sex remains a normal part of many people's lives in their sixties and seventies.

The real downsides (and how to avoid them)

Masturbation is low-risk, but not zero-risk. Cleveland Clinic describes a few issues worth knowing about (Cleveland Clinic, 2022):

Hygiene matters too. Wash your hands first, clean any toys according to the manufacturer's instructions after every use, and do not share toys without cleaning them properly. If something hurts, stop.

This article is for general education and is not a substitute for medical advice. Talk to a doctor or urologist if you notice pain, blood in your semen or urine, difficulty urinating, sores that do not heal within a few days, or any sudden change in erections or ejaculation. Speak with a mental health professional or a certified sex therapist if masturbation feels out of your control, or if guilt or anxiety about it is affecting your daily life.

The bottom line

The evidence supports a calm, practical view. Masturbation is normal at every age, has no serious side effects, and is linked with some positive outcomes, from relaxation and self-reported sleep to a lower rate of low-risk prostate cancer in one large study. Most of these benefits are associations, not proven effects. You do not need to masturbate more for your health, and you do not need to stop for your health either. What matters most is that it feels good, causes no pain, and fits comfortably into the rest of your life.
