The Male Reproductive System

Friday, 21 July 2017

How Does the Male Reproductive System Function?
The purpose of the organs of the male reproductive system is to perform the following functions:

To produce, maintain, and transport sperm (the male reproductive cells) and protective fluid (semen)
To discharge sperm within the female reproductive tract during s*x
To produce and secrete male s*x hormones responsible for maintaining the male reproductive system

Unlike the female reproductive system, most of the male reproductive system is located outside of the body. These external structures include the man-hood, scrotum, and testicles.

man-hood: This is the male organ used in s*xual intercourse. It has three parts: the root, which attaches to the wall of the abdomen; the body, or shaft; and the glans, which is the cone-shaped part at the end of the man-hood. The glans, also called the head of the man-hood, is covered with a loose layer of skin called foreskin. This skin is sometimes removed in a procedure called circumcision. The opening of the urethra, the tube that transports semen and urine, is at the tip of the man-hood. The glans of the man-hood also contains a number of sensitive nerve endings.

The body of the man-hood is cylindrical in shape and consists of three circular shaped chambers. These chambers are made up of special, sponge-like tissue. This tissue contains thousands of large spaces that fill with blood when the man is sexually aroused. As the man-hood fills with blood, it becomes rigid and erect, which allows for penetration during s*xual intercourse. The skin of the man-hood is loose and elastic to accommodate changes in man-hood size during an erection.

Semen, which contains sperm (reproductive cells), is expelled (ejaculated) through the end of the man-hood when the man reaches s*xual climax (climax). When the man-hood is erect, the flow of urine is blocked from the urethra, allowing only semen to be ejaculated at climax.

Scrotum: This is the loose pouch-like sac of skin that hangs behind and below the man-hood. It contains the testicles (also called testes), as well as many nerves and blood vessels. The scrotum acts as a “climate control system” for the testes. For normal sperm development, the testes must be at a temperature slightly cooler than body temperature. Special muscles in the wall of the scrotum allow it to contract and relax, moving the testicles closer to the body for warmth or farther away from the body to cool the temperature.

Testicles (testes): These are oval organs about the size of large olives that lie in the scrotum, secured at either end by a structure called the spermatic cord. Most men have two testes. The testes are responsible for making testosterone, the primary male s*x hormone, and for generating sperm. Within the testes are coiled masses of tubes called seminiferous tubules. These tubes are responsible for producing sperm cells.
The internal organs of the male reproductive system, also called accessory organs, include the following:

Epididymis: The epididymis is a long, coiled tube that rests on the backside of each testicle. It transports and stores sperm cells that are produced in the testes. It also is the job of the epididymis to bring the sperm to maturity, since the sperm that emerge from the testes are immature and incapable of fertilization. During s*xual arousal, contractions force the sperm into the vas deferens.

Vas deferens: The vas deferens is a long, muscular tube that travels from the epididymis into the pelvic cavity, to just behind the bladder. The vas deferens transports mature sperm to the urethra, the tube that carries urine or sperm to outside of the body, in preparation for Release.

Ejaculatory ducts: These are formed by the fusion of the vas deferens and the seminal vesicles (see below). The ejaculatory ducts empty into the urethra.

Urethra: The urethra is the tube that carries urine from the bladder to outside of the body. In males, it has the additional function of ejaculating semen when the man reaches climax. When the man-hood is erect during s*x, the flow of urine is blocked from the urethra, allowing only semen to be ejaculated at climax.

Seminal vesicles: The seminal vesicles are sac-like pouches that attach to the vas deferens near the base of the bladder. The seminal vesicles produce a sugar-rich fluid (fructose) that provides sperm with a source of energy to help them move. The fluid of the seminal vesicles makes up most of the volume of a man’s ejaculatory fluid, or release.

Prostate gland: The prostate gland is a walnut-sized structure that is located below the urinary bladder in front of the rectum. The prostate gland contributes additional fluid to the release. Prostate fluids also help to nourish the sperm. The urethra, which carries the release to be expelled during climax, runs through the center of the prostate gland.

Bulbourethral glands: Also called Cowper’s glands, these are pea-sized structures located on the sides of the urethra just below the prostate gland. These glands produce a clear, slippery fluid that empties directly into the urethra. This fluid serves to lubricate the urethra and to neutralize any acidity that may be present due to residual drops of urine in the urethra.
How Does the Male Reproductive System Function?

The entire male reproductive system is dependent on hormones, which are chemicals that regulate the activity of many different types of cells or organs. The primary hormones involved in the male reproductive system are follicle-stimulating hormone, luteinizing hormone, and testosterone.

Follicle-stimulating hormone is necessary for sperm production (spermatogenesis), and luteinizing hormone stimulates the production of testosterone, which is also needed to make sperm. Testosterone is responsible for the development of male characteristics, including muscle mass and strength, fat distribution, bone mass, facial hair growth, voice change, and s*x drive.
