Masturbation is a normal sexual activity with measurable health effects

Masturbation is a form of sexual self-stimulation that most people experience at some point. Research over the past two decades has moved past older stigma and documented real physical and mental effects—some protective, some worth understanding in context. The evidence shows that masturbation itself is not harmful, but frequency, context, and how it fits into your overall sexual life do matter for your wellbeing.

This guide covers what peer-reviewed studies actually show about masturbation's relationship to sexual function, mental health, prostate health, and relationship satisfaction. The goal is to give you the facts so you can make informed choices about your own sexual health without shame or misinformation.

Key Takeaways

  • Research shows masturbation does not cause erectile dysfunction, infertility, or hormonal imbalance, contrary to older myths.
  • Regular masturbation may lower prostate cancer risk in men and is associated with better sexual function and satisfaction in both sexes.
  • Excessive masturbation that interferes with work, relationships, or daily life may signal compulsive sexual behavior worth discussing with a healthcare provider.
  • Masturbation is a normal part of sexual development and can serve as a way to understand your own body and preferences.
  • Frequency varies widely among individuals and is influenced by age, relationship status, stress, and hormones—there is no single "normal" amount.

Physical health effects supported by research

Studies in urology and sexual medicine have found that masturbation does not damage sexual organs or cause the problems historically attributed to it. Erectile dysfunction, premature ejaculation, and low testosterone are not caused by masturbation itself. In fact, men who masturbate regularly show no difference in erectile function compared to those who do not, and some research suggests better sexual response overall.

One notable finding comes from a 2016 study in the European Urology journal, which tracked over 31,000 men and found that those who ejaculated more frequently (including through masturbation) had a lower risk of prostate cancer. The protective effect was strongest in men over 50. Researchers theorize that regular ejaculation may flush carcinogens from the prostate, though the exact mechanism is not fully understood.

Masturbation also does not affect fertility or sperm count in men. Semen regenerates continuously, and masturbation does not deplete it or reduce the ability to father children. Women who masturbate show no changes to reproductive health or hormonal balance.

Mental health and stress relief

Masturbation triggers the release of several neurochemicals: dopamine (associated with pleasure and reward), oxytocin (linked to bonding and stress relief), and endorphins (natural painkillers). These are the same chemicals released during partnered sex, which is why masturbation can reduce stress and improve mood in the short term.

Research on sexual function and mental health has found that people who have a healthy sexual life—including solo sex—report lower rates of depression and anxiety. A 2010 study in Sexual Medicine Reviews noted that sexual satisfaction (from any source) correlates with better overall life satisfaction and lower stress. Masturbation can be part of that picture, especially for people without partners or during periods of relationship stress.

However, masturbation is not a substitute for addressing underlying depression or anxiety. If you are using masturbation primarily to escape difficult emotions or as a coping mechanism for trauma, talking to a therapist can help you develop a fuller toolkit for managing those feelings.

When masturbation may signal a problem

Masturbation becomes a concern when it interferes with your work, relationships, daily responsibilities, or sexual function with a partner. Compulsive sexual behavior—including excessive masturbation—is recognized in clinical settings and can be a sign of impulse control issues, unresolved trauma, or other mental health conditions that benefit from professional support.

Signs that masturbation may be problematic include: spending several hours per day on it, continuing despite negative consequences (job loss, relationship damage, financial strain), using it to avoid responsibilities or relationships, or experiencing shame and secrecy that causes distress. If masturbation is affecting your life in these ways, a sex therapist or counselor can help you understand what is driving the behavior and develop healthier patterns.

It is also worth noting that some medications (particularly certain antidepressants and antipsychotics) can affect sexual desire and function, including the ability to masturbate. If you notice a sudden change in sexual interest or function after starting a medication, discuss it with your prescribing doctor—there may be alternatives or adjustments that work better for you.

Masturbation and partnered sexual relationships

Masturbation does not reduce sexual desire for partners or cause infidelity. People in committed relationships masturbate for many reasons: different schedules, mismatched libidos, partner absence, or straightforward as part of their own sexual expression. Research shows that solo sex and partnered sex serve different functions and are not in competition.

Some couples incorporate masturbation into their sexual relationship—either together or as part of their individual sexual lives. Others prefer not to. What matters is communication: partners who talk openly about their sexual needs and boundaries, including solo sex, report higher satisfaction and less conflict.

If one partner masturbates more than the other wants, or if masturbation is being used to avoid intimacy, that is a relationship issue worth addressing together, possibly with a sex therapist. The problem is usually not the masturbation itself but unmet needs or unspoken expectations.

Frequency and what counts as normal

There is no medically defined "normal" frequency for masturbation. Studies show enormous variation: some people masturbate multiple times per week, others rarely or never. Frequency changes across the lifespan, with peaks typically in adolescence and early adulthood, and shifts based on relationship status, stress, health, and hormones.

A 2017 survey in JAMA found that about 73% of men and 36% of women reported masturbating in the past year. Among those who did, frequency ranged from a few times per year to several times per week. Age, relationship status, and overall sexual interest all influenced the numbers. The key point: if your frequency is not causing problems in your life or relationships, it is within the normal range.

If you are concerned that you are masturbating too much or too little, the question to ask is whether it is affecting your functioning or causing you distress. If the answer is no, variation from others' patterns is not a problem.

Masturbation across the lifespan

Masturbation is a normal part of sexual development starting in childhood, though the context and meaning change with age. Young children may touch their genitals out of curiosity or comfort; this is developmentally normal and not a sign of abuse or problems. Adolescents typically begin masturbating as part of sexual maturation and exploration, and frequency often peaks in the teenage years and early twenties.

In adulthood, masturbation continues for many people, whether or not they are in relationships. Older adults often continue to masturbate, and research suggests that sexual activity—including solo sex—is associated with better health outcomes and quality of life in aging. Masturbation can be a way to maintain sexual function and pleasure as partnered sex becomes less frequent or more difficult due to health changes.

Pregnancy, illness, disability, and medication can all affect masturbation frequency and function. These changes are normal and do not indicate a problem unless they cause distress or are part of a larger loss of function worth discussing with a doctor.

Frequently Asked Questions

Does masturbation cause erectile dysfunction or reduce sexual performance?

No. Erectile dysfunction is caused by vascular, hormonal, neurological, or psychological factors—not by masturbation. Men who masturbate regularly show no difference in erectile function compared to those who do not. In fact, understanding your own sexual response through masturbation can improve sexual confidence and function with a partner.

Can masturbation affect fertility or sperm count?

No. Semen regenerates continuously, and masturbation does not deplete sperm or reduce fertility. Men can masturbate regularly without any impact on their ability to father children. If you are concerned about fertility, the issue is not masturbation but underlying health factors worth discussing with a doctor.

Is it normal to masturbate if I am in a relationship?

Yes. Many people in committed relationships masturbate, and it does not indicate a problem with the relationship or reduced attraction to their partner. Solo sex and partnered sex serve different purposes. Open communication with your partner about sexual needs and boundaries is what matters most.

What should I do if I think I am masturbating too much?

Ask yourself whether it is interfering with work, relationships, responsibilities, or your own wellbeing. If the answer is yes, talking to a sex therapist or counselor can help you understand what is driving the behavior and develop healthier patterns. If it is not causing problems in your life, variation from others' frequency is normal.

Does masturbation affect hormone levels?

Masturbation causes temporary changes in hormones like dopamine and oxytocin during and shortly after orgasm, but it does not alter baseline testosterone or other hormones. Regular masturbation does not lower testosterone or affect hormonal balance in men or women.
