THE PERIOD OF PROCREATIVE POWER.--The procreative ability begins at puberty. There is no fixed period at which it may be said to end. From puberty until the period of physical maturity, it grows in vigor and it remains stationary until middle life, when it gradually declines. The standard of virility is unquestionably an individual problem. It depends upon the various factors that contribute to good health and longevity. It may be stated that the boy who abused his procreative function, during the period of immaturity, will not enjoy, during the mature period of his sexual life, a normal standard of vigor, nor will he carry the ability into old age, to the same relative degree, as he would, and as he had the innate promise to do--if he had led a normal continent existence. It may also be stated here that there is no effective remedial measures known, that will "bring back" the procreative ability if it is lost as a result of disobeying natural laws. Drugs and treatments by quacks to cure impotence are impositions and fakes. Money and time spent in the pursuit of this dream is money and time wasted. SELF-ABUSE OR MASTURBATION.--By self-abuse is meant the production of the venereal orgasm, with or without emission, by any means other than the natural union of the sexes. It is a fact that the large majority of boys acquire the habit of self-abuse at some time. This is a very serious reflection upon parent, teacher, and physician, because it is through ignorance of the elementary principles of sex hygiene that this condition continues to exist. If they were warned against the possibility of self-abuse arising in innocent ways, as well as in more reprehensible ways, they would exert their influence against its acquirement. If however a boy discovers accidentally a condition of which he was innocent, and of which he does not know the significance, it is human nature that he should investigate the phenomenon and in the end suffer as a consequence. In the effort to relieve some local irritation he may handle himself and be led into a dangerous practice. He does not know that the practice may have serious results--in fact he does not know he is doing anything wrong. Many boys have practically ruined their physical health and become morally irresponsible because no one--neither parent, teacher, physician, nor friend--told them of their danger. This is unjust, but great strides are being made in this direction and we may reasonably hope, that in the not far distant future, every boy will be plainly told the true facts about himself.
