Although common and natural, masturbation continues to raise many questions. Some worry about its impact on sexual health or the body in general. Can it deform the penis, reduce its size, cause chronic fatigue, or lead to erectile dysfunction? Dr. Gilbert Bou Jaoudé, a medical sexologist, offers a scientific and reassuring perspective on the topic.

Does masturbation deform the penis?
Contrary to popular belief, masturbation does not cause penile curvature. Most men naturally have a slight or more pronounced curve, which is generally congenital—that is, genetic. Only severe curvatures that interfere with sexual activity require medical attention.
However, aggressive or traumatic practices during masturbation—such as forcefully bending or compressing the penis—can eventually lead to microtraumas. These may cause a loss of elasticity and deformation during erections. Gentle, body-respecting gestures are therefore essential.
Can the size of the penis or testicles decrease?
No, masturbation has no shrinking effect on the penis or testicles. There is no credible scientific evidence to support this notion—it is a myth, not reality.
Does it cause lasting fatigue?
In most cases, masturbation does not cause chronic fatigue. A feeling of relaxation or drowsiness may occur immediately after orgasm, which is perfectly normal. This temporary sensation is due to the release of hormones and neurotransmitters that promote well-being.
However, a rare condition known as post-orgasmic illness syndrome (POIS) may affect some individuals. This condition is characterized by intense fatigue, discomfort, or other prolonged symptoms after orgasm. In such cases, consulting a sexologist is recommended.
Masturbation and fertility: is there a connection?
Masturbation has no impact on sperm production and does not cause infertility. However, frequent masturbation shortly before intercourse may temporarily reduce semen volume, which can lower—but not eliminate—the chances of fertilization. For couples trying to conceive, spacing out ejaculations may be advisable.
Can it cause erectile or ejaculation issues?
It’s not masturbation itself that causes these issues, but rather how it’s practiced. Compulsive masturbation, done without real desire or as part of an addiction, can affect sexual well-being.
Similarly, developing habits that rely on techniques not replicable during partnered sex—such as excessive pressure or constant use of pornography—can disrupt natural sexual responses. This can lead to a dependency on visual stimuli and difficulty achieving or maintaining an erection during real-life encounters.
And what about other symptoms, like ringing in the ears?
Some people may experience mild side effects such as ringing in the ears or fatigue after orgasm. These are temporary and related to hormonal changes. They are not a cause for concern.
A generally safe practice—if it’s experienced positively
In short, masturbation poses no risk when practiced respectfully, without excess or violence. It can even serve as a healthy moment of self-exploration and contribute to improved sexual function. However, if it becomes compulsive or tied to inappropriate habits, it may lead to discomfort or dysfunction.
In case of persistent doubt or discomfort, it’s always best to consult a qualified healthcare professional.
