What Is The Male Animal Reproductive Hormone

The Male Reproductive System

Medically Reviewed by Nazia Q Bandukwala, DO on March 15, 2022

The purpose of the organs of the male person 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 sex
• To produce and secrete male sex 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 penis, scrotum, and testicles.

• Penis: This is the male organ used in sexual intercourse. Information technology 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 office at the end of the penis. The glans, besides called the head of the penis, is covered with a loose layer of pare called foreskin. This skin is sometimes removed in a procedure chosen 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 likewise contains a number of sensitive nerve endings.

  The torso of the penis 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. 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 accommodate changes in penis size during an erection.

  Semen, which contains sperm (reproductive cells), is expelled (ejaculated) through the end of the penis when the human reaches sexual climax (orgasm). When the penis is erect, the catamenia of urine is blocked from the urethra, allowing only semen to be ejaculated at orgasm.

• Scrotum: This is the loose pouch-like sac of skin that hangs behind and below the penis. It contains the testicles (besides called testes), also as many nerves and blood vessels. The scrotum acts every bit a "climate control system" for the testes. For normal sperm development, the testes must exist at a temperature slightly cooler than body temperature. Special muscles in the wall of the scrotum allow information technology to contract and relax, moving the testicles closer to the body for warmth or further 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 construction called the spermatic cord. Most men have two testes. The testes are responsible for making testosterone, the chief male sexual practice hormone, and for generating sperm. Inside 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 arrangement, as well 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 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 backside the bladder. The vas deferens transports mature sperm to the urethra, the tube that carries urine or sperm to outside of the trunk, in preparation for ejaculation.

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

• Urethra: The urethra is the tube that carries urine from the bladder to exterior of the body. In males, information technology has the additional function of ejaculating semen when the human being reaches orgasm. When the penis is erect during sex, the menstruation of urine is blocked from the urethra, allowing simply semen to exist ejaculated at orgasm.

• Seminal vesicles: The seminal vesicles are sac-similar pouches that attach to the vas deferens near the base of operations of the bladder. The seminal vesicles produce a saccharide-rich fluid (fructose) that provides sperm with a source of free energy to aid them move. The fluid of the seminal vesicles makes up near of the volume of a man's ejaculatory fluid, or ejaculate.

• Prostate gland: The prostate gland is a walnut-sized structure that is located beneath the urinary bladder in front of the rectum. The prostate gland contributes additional fluid to the ejaculate. Prostate fluids also assistance to attend the sperm. The urethra, which carries the ejaculate to be expelled during orgasm, runs through the center of the prostate gland.

• Bulbourethral glands: Likewise chosen Cowper's glands, these are pea-sized structures located on the sides of the urethra but 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 whatever acidity that may be present due to residual drops of urine in the urethra.

How Does the Male Reproductive Organisation Function?

The entire male person reproductive system is dependent on hormones, which are chemicals that regulate the action of many unlike types of cells or organs. The primary hormones involved in the male person 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 person characteristics, including muscle mass and force, fat distribution, bone mass, facial hair growth, voice change, and sex drive.
