parts and functions: male reproductive system


 14 parts of the male reproductive system and their functions

Prostate

The prostate is a gland in men that helps to make semen, the fluid that contains sperm. The prostate surrounds the tube that transports urine away from the bladder and out of the body. A young man’s prostate is about the size of a walnut. It slowly grows larger with age.

Seminal vesicle

The seminal gland, as well known as the seminal vesicle, holds the liquid that mixes with sperm to form semen. Semen is made up of fluid from the epididymis, seminal vesicle, prostate gland, and vas deferens. The fluids help the sperm swim towards the egg and keep the sperm nourished during the traveling process.

Rectovesucal pouch

This is a sac between the rectum and the urinary bladder in males that is formed by a folding of the peritoneum.Its bottom is slightly below the level of the upper ends of the vesiculae seminales—i. e., about 7.5 cm. from the orifice of the anus. A membranous partition known as the Rectoprostatic fascia (Denonvillier’s fascia) is situated at the lowest part of the rectovesical pouch.

Rectum

The rectum is the concluding part of the large intestine that terminates in the anus. The average length of the human rectum may range between 10 and 12 cm. It gets dilated near the anus, where it forms the rectal ampulla. Its major role is to act as a temporary storehouse for feces.

Anus

The anus is the opening where the gastrointestinal tract ends and exits the body. The anus starts at the bottom of the rectum, the last portion of the colon (large intestine). The anorectal line separates the anus from the rectum. Tough tissue known as fascia surrounds the anus and attaches it to the structures close by.

Bulb of penis

The bulb of penis means the bottom portion of the penis. It is as well referred to as the base of the penis. The bulb is made up of a large bundle of tissue. The tissue mass expands from the corpus spongiosum. The bulb is situated above the scrotum, which is the swelling that contains the testicles.

Scrotum

The scrotum is a part of the external male genitalia situated behind and under the penis. It is the small muscular sac that contains and protects the testicles, blood vessels, and part of the spermatic cord. It is divided interiorly into two sections by a septum, and each section contains a testicle. The scrotum protects the testicles from temperature changes

Testicle

Testicles, or testes, produce male hormones and sperm. They are two egg-shaped organs inside the scrotum, the loose sac of skin behind the penis. It’s easy to injure your testicles due to the fact that they are not protected by bones or muscles. Men and boys should wear athletic supporters when they play sports.

Epididymus

The epididymis is a long, coiled tube that stores sperm and transports it from the testes. It appears as a curved structure on the posterior margin of each testis, and is made up of three sections known as the head, body, and tail. Though it looks superficially like the testes, the epididymis is smaller, and the tubes are larger and less densely packed.

Fore skin

The foreskin represents at least a third of the penile skin and protects the glans from abrasion and contact with clothes. The foreskin as well increases sexual pleasure by sliding up and down on the shaft, stimulating the glans by alternately covering and exposing it. This can occur during masturbation or intercourse.

Glans

The glans penis can mainly be described as the rounded head of a penis. Located in the middle of the glans penis is the opening of the urethra. At birth, the glans of the penis is attached to an area of skin called the foreskin. Over time, this foreskin will begin to break up from the glans, until the skin is able to full retract.

Penis

The human penis is an external male sexual organ. It is a reproductive, intermittent organ that additionally serves as the urinal duct. A penis is the primary sexual organ that male and hermaphrodite animals use to inseminate sexually receptive mates during sexual intercourse. A penis can be fractured if it is forcefully bent when engorged.

Urethra

The urethra is the tube through which urine passes out of the body. In men, it’s a long tube that runs through the penis. It also carries semen in men. In women, it’s short and is just above the vagina. Urethral problems may happen due to aging, illness, or injury.

Urinary bladder

The urinary bladder is a muscular sac in the pelvis, just above and behind the pubic bone. When empty, the bladder is about the size and shape of a pear. Urine is produced in the kidneys, and travels down two tubes known as ureters to the bladder. The bladder stores urine, permitting urination to be infrequent and voluntary.
