ANATOMY AND PHYSIOLOGY OF THE MALE ORGANS
A knowledge of the structure and functions of the sex organs is essential to an understanding of the sexual question. When one is able to visualize the remarkable mechanism of the reproductive system, he will have a more wholesome respect for his sexual gifts, and a greater appreciation of their responsibilities.
Unlike the corresponding organs of the female—which are nearly entirely within the body and concealed—the penis and testes of the male are external organs.
The Penis. The penis, also called the "membrum virile," is a muscular organ composed of erectile tissue containing numerous blood vessels. An analysis of its structure discloses that it is of three parts or bodies extending lengthwise, bound together by fibrous tissue.
