The Male Reproductive System

By Brandon

What does the system do?

The basic function of the reproductive system is to discharge sperm to the egg cell while they exchange gametes. Which later they pass onto their offspring. The major organs of this system are the testes, vas deferens, urethra, and penis.

Inside the testes small cells called sperm are created. Sperm is created by little germ cells and it takes up to seventy days for the cells to become full mature sperm cells. While reproducing the sperm is carried from the testes into the vas deferens which is a tube that leads to the prostate gland. As the sperm gets there it's covered by a protective seminal fluid which is called semen. As that happens the sperm and semen travel down a second tube called the urethra. The urethra is located in the penis which is another reproductive organ. It tells the brain to start releasing sperm. As the sperm and semen reach the end of the urethra it's released from the body. When it's released that term is called "ejaculation"

Once out the body the sperm have to find their way to the ovaries to get to the egg cell. Over 40 to 60 million sperm cells are released and only one will be able to get to the egg cell. As one sperm gets to an egg the egg cell will create a protective wall around itself preventing any other sperm from entering and the rest die off.

When the last remaining sperm cell is inside it'll shed it's outer layer and exchange gametes (genetic material) with the egg.


The male reproductive systems is very prone to many diseases. Most of them are sexually transmitted disease (STDs) for short. One of the most common diseases that are transferred from this system is HIV (Human Immunodeficiency Virus) which can eventually lead to AIDS (Acquired Immunodeficiency Syndrome) but can spread in many other ways such as sharing needles but mostly common through sexual intercourse. Other infections are gonorrhea, syphilis, and chlamydia. A way for these things to be prevented are to use a condom or abstinence.

Homeostatic Imbalances

The most common of the homeostatic imbalances is cancer. The most common one and the most treated is testicular cancer. Early symptoms of the disease start out with a hard lump on one of the testicles. It's about as big as a pencil eraser and feels like a small stone. It's not mobile meaning that it's attached to the testicle. If caught early it can be removed surgically and that would be it. If not caught early then it would have to be treated with traditional treatment. If caught late then there's nothing much that could be done.

Another one is cryptorchidism, which means that the testes are stuck in the stomach and do not descend from the body. If they're inside the stomach for too long then there's a high chance of the testicles developing cancer. This usually happens in newborn infants, but after four to six months the testes will go back to their original position. If that's not successful then there's a series of hormonal injections.

The next and final one is prostate cancer. Unlike testicular cancer which is common in younger men prostate cancer is more common in older men. About 99% of diagnosis come from men over 50. It can come from genetics or lifestyle choices. For example if you lack vitamin D in your body your chances of prostate cancer increase. When diagnosed the treatment is pretty much the same as all cancer treatments.
