The male reproductive system

The male reproductive system is far less complicated although it involves a lot of pipes and tubes.

In Men, the main reproductive structures are

  • Penis
  • Scrotum
  • Testes

Men have many supporting structures that aid the production, storage and passage of sperm from the testes to the penis. These supporting structures are:

  • Epididymis
  • Spermatic Cords, Vas Deferens (or Ductus Deferens)
  • Seminal Vesicles
  • Ejaculatory Duct and Urethra
  • Prostate

The most important organs of the male reproductive system are the testes. The testes or testicles are responsible for producing sperm and testosterone. Because sperm requires a cooler temperature than the human body in order to be healthy, the testicles are kept away from the body in a sac-like organ called the scrotum. The scrotum adjusts the distance of the testes from the body to ensure the perfect temperature to produce sperm.

Once the sperm is manufactured in the testes, they are stored in a long coiled pipe called the epididymis which is located within the scrotum right next to the testes. The length of the epididymis is useful to allow the sperm to mature before they are passed on to the other parts of the male reproductive organs.

The epididymis is connected to a tube called the Vas deferens or Ductus Deferens. This tube moves sperm from the scrotal area, to the penis for ejaculation. The walls of the tube are made of smooth muscles that help move the sperm along the path. You may have heard of the birth control method called Vasectomy. Doctors clamp down and cut this tube, the Vas Deferens, to prevent the passage of sperm from the testes to the penis.

Now the vas deferens loops behind the urinary bladder and in front of the rectum. In this area there is a gland called the Seminal Vesicle that produces some of the fluid found in semen. This fluid is important to keep sperm alive. It is made of proteins and mucus that create a basic environment so that the sperm can survive the acidic environment of the vagina. The fluid also contains fructose that feeds the sperm so that they have enough energy to fertilize a female egg.

The seminal vesicle connects into the ejaculatory duct which is basically a tube that connects into the urethra. This ejaculatory duct passes through the Prostate that contributes a large amount of fluid in semen. This fluid contains enzymes, chemicals, and proteins that help nurture the sperm and is milky white in color.

After this, the sperm passes into the urethra which is a tube in the penis that passes urine and semen out of the body. Since urine is acidic and semen is basic, there are other glands located near the prostate that release mucus that helps neutralize the path for sperm to pass before ejaculation.
