The erroneous beliefs concerning physiological necessity have been propagated chiefly on the authority of advertising medical fakers, whose business depends on misrepresentation and deceit, men whose methods exclude them from the ranks of reputable physicians. They are also taught by those within the ranks of the profession who are ignorant or unscrupulous or both, and who for the most part have no higher incentive in their profession than the pursuit of the dollar. The teaching of these men is in most cases more an expression of their own vicious habits than of real conviction. Both wholly misrepresent the teaching and attitude of the great majority of physicians who constitute the reputable body of the profession. Dr. William H. Howell, Professor of Physiology at Johns Hopkins University, says: "There is no evidence whatsoever that the sexual appetite or the act of reproduction has any physiological relationship to the preservation of the integrity of the individual. This appetite has been created or evolved and made strong in us for an entirely different purpose. A sexual necessity exists only so far as the integrity of the race is concerned; so far as the individual is concerned his sexual functions may be unused or he may be completely unsexed without any injury to his bodily health."
