The Generative Organs of man consists of two distinct outward members, called the Penis and the Testes, or Testicles—both together being frequently called the Genitals. The Testes are inclosed in a sac or bag hanging from the pubic bone called the Scrotum, and their functions are to produce the male principle or Semen, as the Ovaries in the female ripen the Ovum or Egg. The Testes are a curious work of Nature. On dissection they are found to be composed of fine blood vessels intermingled with small tubes called the Seminal Tubes, in which the Semen is generated. Some very knowing physicians say that there are sixty thousand of these Seminal Tubes; but we doubt if anybody ever counted them. These tubes, as they leave the Testes, gradually join together until finally a single tube only goes from each Testicle. These are called the Vas Deferens, and they ascend to the abdomen through a larger tube, (which also contains arteries, nerves, lymphatics, &c.,) where they connect with two small organs called Seminal Vesicles. From these vesicles the Semen passes downwards through a tube called the Ejaculatory Canal, which is connected with the Prostate Gland, and from whence it is forced to the Urethra or urinal passage, and so out of the body. This is a brief outline of all the organs connected with the generative system of man: the Testes have the peculiar property of making the Semen—the Vas Deferens and the Ejaculatory Canal carry it into the abdomen to the Prostate Gland, from whence it is conveyed, by a peculiar but spasmodic effort, through the urinal passage in the Penis into the body of the female. It is supposed that the Seminal Vesicles and Prostate Gland impart a vital principle to the Semen, and that the peculiar pleasurable feeling experienced during connection with the female springs from these organs. The Scrotum, in a healthy state, is contracted so as to draw its skin into folds and keep the Testes close to the body. But when a person is in ill health, or greatly fatigued, the skin relaxes and the two Testes hang low, the Scrotum being then supported in the middle by a membrane or cord called the Septum Scroti, which acts as a sort of partition. The Scrotum of old men is permanently relaxed in this manner; but in children it is a sure indication of ill health.
