The male reproductive system

The male reproductive system consists of the penis, testicles, scrotum, epididymis, vas deferens, seminal vesicles, prostate gland and urethra or urinary passage. The scrotum, which resembles a divided pouch, contains the testicles.

The left side usually hangs slightly lower than the right. The scrotum changes in appearance and size depending on various factors such as temperature, etc.

Normally, the testicles are found in the scrotum. They can, however, be pushed through the inguinal canal into the groin. In some cases, they remain there from birth and fail to descend at all. This condition is called undescended testicle.

If both testicles fail to descend, a man will be sterile because the body temperature is too high for the development of spermatozoa. Sometimes, surgical treatment is necessary to relieve this condition, or it may be treated with hormones.

The testicles are a pair of small oval glands, about one and one-half inches long, an inch wide and less than an inch thick. Like the ovaries, they perform two functions, secretion of male sex hormones, and the manufacture of spermatozoa, the male genetic seed.

Inside the testicle (testis) is a series of small canals called the seminiferous tubules, in which the sperm is manufactured.

The tubules come together in larger tubes called the epididymis. The sperm travels through this passage and into the vas deferens, which leads into the abdominal cavity. The vas deferens joins the seminal vesicle, which produces a secretion that causes the sperm to become active.

From here, it passes through the prostate gland which adds a secretion that further stimulates the sperm.

The fluid containing the spermatozoa is called  semen. It is stored in the seminal vesicles and prostate gland. Under sexual excitement, it is forcefully and spasmodically ejected through the urethra.

 The process is called ejaculation. About one teaspoonful of semen is ejaculated at one time. It contains about one hundred million sperm. The urethra passes through the penis, with its opening in the glans, or head.

The penis is a soft, spongy organ, honeycombed with blood vessels and tissues which greatly increases in size when distended with blood. When relaxed, the size of the penis is from one to three inches long and approximately one inch in diameter.

When erect, it is usually between five and seven inches long and one and one-quarter to one and one-half inches in diameter. Relaxed, it hangs limply over the testicles, but erect, it curves upward and outward from the body.

Secretions, known as smegma, collect under the foreskin, the exposed head of the penis, after circumcision, becomes a little less sensitive, which helps to check premature ejaculation.

The practice of personal hygiene is extremely important to every man. A two-day stubble or ragged fingernails will fail to attract the most devoted of wives.

Body odors are almost always offensive. If it is not possible to bathe every day, the penis should be washed daily with soap and water.

The foreskin of the uncircumcised male should be pulled back and the inner area thoroughly cleaned.

Perspiration zones, such as the armpits, crotch and feet should be washed.  However, women may like natural body odors – and females of all ages are ever, more sensitive to odors than males. Therefore, the wise man will take pains to smell attractive.

The head of the penis, known as the glans, is slightly larger in diameter than the rest. It contains very sensitive nerve-endings which produce intense sensory stimulation, like in the clitoris, bringing about the climax or orgasm. As is often the case, over-sensitivity may result in premature ejaculation.

At birth, the head of the penis is covered by a narrow fold of skin called the prepuce, or foreskin. Few physicians agree that all boy babies should be circumcised, that is, that the foreskin should be removed.

THE ENDOCRINE GLANDS

The endocrines are also known as the ductless glands or glands of internal secretion. They are the pituitary, pineal, thyroid, parathyroid, pancreas, adrenals, ovaries and testes (testicles).

Active, functioning glands imbue the whole body and mind with a youthful vigor, self-confidence and optimism. They either control or influence such widely divergent attributes as height, ability to concentrate, color of the skin, muscular development, sexual vigor, reproduction, a woman’s gracefulness and the frequency of a man’s need to shave.

Hormones have the power of initiating and stimulating the activities of different organs and tissues. It is believed that each hormone has a specific role in the mechanism of the body.

There is also considerable evidence that the various glands have  reciprocal action upon each other, and that if one does not function properly the others, too, may become affected. The endocrine glands may be compared to minute chemical laboratories.

They extract materials from the blood stream, convert them into hormones and return them to the blood which carries them, along with other materials, to every cell in the body. Each endocrine gland serves a special purpose and manufactures its own unique product.

The hormones secreted by the adrenal glands, a pair of little caps sitting astride the kidneys, are absolutely essential Deficiency of the other hormones, while not fatal, results in lessened physical, mental and emotional health.

The pituitary gland, called the “Master Gland”, controls the activity of all the endocrine glands. It is a small gland, about the size of an acorn, situated in the most protected spot in the whole body. It hangs under the brain, sheltered not only by the mass of brain tissue but by the roof of the mouth and the hard shell of the skull.

The section of the gland called the anterior pituitary is the part that exercises influence over the other glands. In this book, we are concerned only with the action of the gonads or sex glands, the ovaries and testes.
