What Makes Up The Male Reproductive System

The Male Reproductive Organization

The purpose of the organs of the male reproductive organization is to perform the following functions:

To produce, maintain, and transport sperm (the male reproductive cells) and protective fluid (semen)
To belch sperm within the female reproductive tract during sex activity
To produce and secrete male person sex hormones responsible for maintaining the male person reproductive system

Unlike the female reproductive system, most of the male reproductive system is located outside of the torso. These external structures include the penis, scrotum, and testicles.

Penis: This is the male organ used in sexual intercourse. It has 3 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 terminate of the penis. The glans, also called the head of the penis, 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 penis. The glans of the penis also contains a number of sensitive nerve endings.

The body of the penis is cylindrical in shape and consists of three circular shaped chambers. These chambers are fabricated upward of special, sponge-similar tissue. This tissue contains thousands of large spaces that fill with blood when the man is sexually aroused. Equally the penis fills with claret, it becomes rigid and erect, which allows for penetration during sexual intercourse. The skin of the penis is loose and elastic to arrange changes in penis size during an erection.

Semen, which contains sperm (reproductive cells), is expelled (ejaculated) through the end of the penis when the homo reaches sexual climax (orgasm). When the penis is erect, the flow of urine is blocked from the urethra, assuasive simply semen to exist ejaculated at orgasm.

Scrotum: This is the loose pouch-like sac of skin that hangs behind and beneath the penis. It contains the testicles (also called testes), likewise as many fretfulness and claret vessels. The scrotum acts equally a "climate control organization" for the testes. For normal sperm development, the testes must be at a temperature slightly cooler than trunk temperature. Special muscles in the wall of the scrotum permit it to contract and relax, moving the testicles closer to the body for warmth or farther away from the torso to cool the temperature.

Testicles (testes): These are oval organs about the size of large olives that lie in the scrotum, secured at either terminate by a structure called the spermatic cord. Virtually men have 2 testes. The testes are responsible for making testosterone, the primary male sex 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 chosen accompaniment 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 besides is the job of the epididymis to bring the sperm to maturity, since the sperm that sally from the testes are immature and incapable of fertilization. During sexual 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 but behind the bladder. The vas deferens transports mature sperm to the urethra, the tube that carries urine or sperm to exterior of the trunk, in preparation for ejaculation.
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 homo reaches orgasm. When the penis is erect during sex activity, the menstruum of urine is blocked from the urethra, allowing only semen to be ejaculated at orgasm.
Seminal vesicles: The seminal vesicles are sac-like pouches that attach to the vas deferens most the base of the bladder. The seminal vesicles produce a carbohydrate-rich fluid (fructose) that provides sperm with a source of energy to assistance them move. The fluid of the seminal vesicles makes up almost of the volume of a human being'south ejaculatory fluid, or ejaculate.
Prostate gland: The prostate gland is a walnut-sized structure that is located beneath the urinary bladder in front end of the rectum. The prostate gland contributes boosted fluid to the ejaculate. Prostate fluids as well aid to nourish the sperm. The urethra, which carries the ejaculate to be expelled during orgasm, 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 articulate, slippery fluid that empties directly into the urethra. This fluid serves to lubricate the urethra and to neutralize any acidity that may exist present due to residual drops of urine in the urethra.

How Does the Male Reproductive System Role?

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 chief hormones involved in the male reproductive system are follicle-stimulating hormone, luteinizing hormone, and testosterone.

Follicle-stimulating hormone is necessary for sperm product (spermatogenesis), and luteinizing hormone stimulates the production of testosterone, which is also needed to make sperm. Testosterone is responsible for the evolution of male characteristics, including muscle mass and strength, fatty distribution, bone mass, facial hair growth, vox alter, and sex drive.
