I consider phosphorus of greater value when this condition is connected with onanism than when arising from over-fatigue or other causes. The irritation is marked by local discomfort, a burning pain in the lumbar region, sense of fatigue and impaired walking power, mental distress, etc. In such cases it is essential that the patient exert moral control over himself, and that treatment be continued judiciously for some months. The remedy relieves the spinal pain and the mental depression, and thus indirectly tends to lessen abnormal sexual desire.
