Harms of masturbation: between fact and myth

Reviewed by: Dr. Mahmoud El-Sawy Last updated: September 28, 2026 11 min read
The short answer

Masturbation does not cause blindness, infertility, hair loss, back pain or "weak spinal cord" as is rumored, and there is no scientific evidence for these myths. The real harms appear when the behavior becomes compulsive: guilt, anxiety and low mood, wasted time and sleep, declining performance at school or work, distance in relationships, and sometimes minor local skin irritation. Most of these improve as control is regained.

  • Fear of the myths sometimes causes more anxiety and obsession than the behavior itself.
  • Harm is linked to loss of control, secrecy and wasted time, not to the existence of the behavior.
  • Overwhelming guilt or thoughts of self-harm call for immediate help.

Does masturbation have real harms? A balanced view

This is among the most searched questions in Egypt and the Arab world, surrounded by inherited fears that have no scientific basis. The honest medical view is that the behavior in itself does not cause physical illness, while a compulsive pattern can cause real psychological and social harm that deserves attention.

Because fear and misinformation cause great suffering, especially for teenagers, we begin by debunking the best-known myths, then move on to the real harms and when they appear. The aim is to put things in their proper proportion, without downplaying or exaggerating.

Common myths in Egypt: what does science say?

Medical sources, including Cleveland Clinic and Nemours KidsHealth, agree that these fears are not supported by any scientific evidence:

The best-known myths about the harms of masturbation
The mythWhat does science say?
Causes blindness or weak eyesightIt has no connection to the eyes or vision. Poor eyesight has well-known genetic and health causes.
Causes infertilityIt does not affect fertility or the ability to have children, in men or women.
It causes hair loss or baldnessHair loss is linked to genetics, hormones, nutrition, stress and some illnesses, not to this behavior.
It causes back pain or "erosion of the spinal cord" or discsIt has no connection to the spine or spinal cord. Back pain is most often linked to prolonged sitting and lack of movement.
It causes "general weakness" and emaciationFatigue is usually the result of staying up late, lack of sleep, anxiety and irregular eating.
It causes sexual dysfunction or infertility after marriageThere is no evidence that it causes permanent weakness. Anxiety and stress are common causes of performance problems, and they should be evaluated by a doctor.
It causes mental illness or "madness"It does not cause mental illness, but the guilt and anxiety that accompany a compulsive pattern may affect mood.
It causes acneAcne is linked to puberty hormones and skin type, and it appears at the same age when the behavior begins, so some people assume the two are connected.

The fear itself may be the greatest harm

Young people come to psychiatric clinics living in constant worry that they have "ruined" their bodies, interpreting every headache, bout of hair loss or episode of fatigue as a result of this behavior. This anxiety can turn into obsessive thoughts that consume the day, into unnecessary repeated medical tests, or into isolation and shame about marriage.

Accurate information is itself a treatment here. But if the distressing thoughts continue despite reassurance and keep recurring in a way that is hard to stop, they may be part of obsessive-compulsive disorder (OCD) or health anxiety, and deserve a psychological assessment.

Psychological harms of the compulsive pattern

When a person loses control over the behavior, real psychological harms appear, and the relationship runs in both directions: distress drives the behavior, and the behavior and the guilt that follows deepen the distress.

The guilt cycle

Constant self-blame, promises that do not hold, and a sense of failure after every time.

Persistent anxiety

Tension when trying to stop, and worry about being found out or about imagined harms.

Low mood

Dullness and loss of pleasure, which may develop into depression that needs treatment.

Lower self-esteem

A sense of living a double life between the outward image and the hidden behavior.

Psychological harms of the compulsive pattern

It is only honest to say that many studies in this field are correlational studies that do not prove cause and effect, and that their results are influenced by the participants' value backgrounds. But specialists agree that loss of control, however it is explained, is linked to real distress that usually eases when the person regains control.

Time, sleep, study and work

The time the compulsive pattern consumes has to come from somewhere: from sleep, study or work. Repeated late nights cause daytime exhaustion and poor concentration, and this is often what explains the "general weakness" some people complain of, rather than the behavior itself. With repeated mental preoccupation, the ability to complete long tasks declines.

Relationships and married life

A compulsive pattern may lead to isolation and withdrawal from friends and social activities, and avoidance of emotional closeness. In married life it can cause distance and misunderstanding, especially when combined with compulsive pornography use and the concealment and unrealistic expectations that come with it. Frank conversation and specialized support help both partners.

The real physical effect: limited and temporary

The proven physical harms are limited. With very frequent repetition, minor local skin irritation or friction may occur and usually clears within days; see a doctor if it persists or comes with pain or inflammation. Anything else, such as fatigue and headache, is mostly linked to staying up late, lack of sleep and stress, and improves with a better routine.

Overwhelming guilt and the risk of self-harm

Some young people and teenagers go through moments of deep despair because of guilt, after their family discovers the behavior, or after harsh scolding. Overwhelming shame can convince a person that he does not deserve to live, and that idea comes from pain, not from the truth.

If you or someone you know has thoughts of death or self-harm, this deserves help now: talk to someone you trust, and call the mental health support line 16328 or ambulance (123). The problem is treatable, and no one should pay for it with their life.

Can the harms of compulsive masturbation be avoided?

Yes, and most of them are reversible: sleep and concentration improve within weeks of changing the routine, mood improves as the cycle of guilt is broken and any accompanying anxiety or depression is treated, and relationships improve with conversation and support. The key is early intervention and accurate information; you will find the practical steps on the page treatment of masturbation.

Crushing shame or thoughts of self-harm? Get help now

  • Talk of wanting to die or that they "don't deserve to live" because of this behavior
  • Severe shame and despair after a relapse, with a conviction of being "hopeless" or "corrupt"
  • A teenager who is distraught or panicked after their family found out, or after threats or harsh punishment
  • Sudden withdrawal from family and friends and stopping eating, sleeping or studying
  • Increased use of alcohol, drugs or sedatives to bear the guilt

Stay with the person and listen calmly, and reassure them that what they are going through is common and treatable and that they are not a bad person; blame at this moment increases the risk. Call an ambulance on 123 or take them to the nearest emergency room, or call the mental health support line 16328 (24 hours), and do not leave them alone as long as thoughts of self-harm are present.

Frequently asked questions about the harms of masturbation: fact vs. myth

Ask on WhatsApp
Does masturbation cause blindness?

No. This is an old myth with no scientific evidence, and the behavior has no connection to the eyes or vision. If you notice weakening eyesight, see an eye doctor to look into its known causes.

Does masturbation cause infertility?

No. According to medical sources, it does not affect fertility or the ability to have children in men or women. Any worry about fertility should be discussed with a specialist doctor, with appropriate tests.

Does masturbation cause hair loss?

There is no scientific evidence for that. Hair loss is linked to genetics, hormones, nutrition, stress and some illnesses, and it should be assessed by a dermatologist.

Does masturbation weaken the back or the spinal cord?

No. This is one of the best-known myths in our societies and has no basis. Back pain is mostly linked to how you sit, lack of movement and lifting heavy loads.

Why do I feel exhausted and weak after a period of compulsive masturbation?

Usually because of staying up late, lack of sleep, stress and the accompanying guilt, not because of the behavior itself. Regulating sleep, physical activity and reducing anxiety clearly improve energy.

Does masturbation affect marriage later on?

The behavior in itself does not cause permanent weakness. But a compulsive pattern, especially with pornography and anxiety, can affect closeness and expectations, and this improves with treatment and frank conversation.

Is constant worry about the harms of masturbation a form of OCD?

It can be, if the thoughts are repetitive and distressing and hard to stop despite reassurance. In that case a psychological assessment helps, since OCD and health anxiety respond well to treatment.
