This question has probably been asked by almost everyone at some point in their lives. But the answers we receive vary from "it is very good" to "it is very bad".

I can understand that becoming obsessive about it is bad (in fact becoming obsessive about anything is bad). But this seems a psychological effect, not one that brings actual physical harm.

Is there any definite evidence to say that it is good or bad ?

By bad, I mean do we see any definite physical effects like impotency, nerve weakness (some people say your nerves weaken), etc?

    Given the fact that primitive cultures have successfully started fires via friction, I would say there is a definite possibility that there might be bad consequences. – user5341 May 6 '11 at 5:58

    I think the proof to the contrary is that there seem to be a lot of post-teen boys walking around on the planet in good health. – JohnFx Jun 4 '11 at 20:25

Masturbation is in NO way bad for your health.

Just keep in mind...

Masturbation is very safe -- but not entirely safe.

But masturbation safety isn't guaranteed. "Masturbation is just about the safest sex there is," says Cornog. "But the laws of physics and biology don't stop operating just because someone is masturbating."

In certain extremely rare instances, masturbation and partner sex alike can cause penile fracture, which is a medical emergency that often necessitates surgery - source

Prostate Cancer

Some interesting research...

Whereas frequent overall sexual activity in younger life (20s) increased the disease risk, it appeared to be protective against the disease when older (50s). Alone, frequent masturbation activity was a marker for increased risk in the 20s and 30s but appeared to be associated with a decreased risk in the 50s, while intercourse activity alone was not associated with the disease. - Sexual activity and prostate cancer risk in men diagnosed at a younger age


The researchers theorize that it may not be the masturbation itself which is increasing risk of prostate cancer in men who masturbate frequently in their 20s and 30s. Men who masturbate more may do so because they have high levels of male sex hormones -- and young men genetically predisposed to have hormone-sensitive prostate cancer will be at higher risk if they have more male hormones. In men over age 50, the researchers theorize, frequent masturbation helps drain the prostate of fluids that may contain cancer-causing substances.. - WebMD

The Bottom Line...

Masturbation is in NO way bad for your health.
