From Ejaculation- How Often for Good Health- – Reuniting   Note reference to Onania . Org

Is there such thing as too frequent ejaculation? The classic view of sexologists is that climax is self-regulating: You can never ejaculate too much, because you’ll simply stop when your body has had enough.

Unfortunately, it looks like not all men automatically stop when their body’s needs are met; ejaculation becomes compulsive. (Just as one third of Americans don’t automatically stop eating and become obese.) For example, the online Onania support group is primarily made up of men who describe their masturbation as compulsive, and acknowledge its negative effects. The group even coined the term "copulatory impotence" for their resulting inability to ejaculate with real partners. Clearly, their bodies did not self-regulate with regard to masturbation. The good news is that this phenomenon is likely reversible.

As we investigated, we discovered research showing that too much ejaculation can cause lingering physiological changes. When men engaged in a "ten-day depletion experience," ejaculating an average of 2.4 times per day, their sperm output remained below pre-depletion levels for more than five months. It’s quite possible that there are other effects occurring in the brain, which haven’t been uncovered yet. The research hasn’t been done.

The absence of comprehensive information may be causing unnecessary suffering. For example, hundreds of men are now recording severe symptoms after ejaculation in the Post-orgasmic Illness Syndrome forum. Many report frequent masturbation in the past. Not long ago, a psychiatrist noted that the neurochemical changes after orgasm are sometimes associated with depression and anxiety in otherwise emotionally healthy patients. Is too much ejaculation dysregulating brains?
