Male Reproductive Organs

Learn all about the male reproductive system and its organs!

What does it do?

The male reproductive system is mainly used during sexual intercourse. During sexual intercourse, the male sex organs work together to release semen into the female reproductive system. Another thing the male sex organs do is help a boy mature into a man, for the main reason that the organs release sex hormones, cause puberty.

What are some of the major organs in this system?

Each of the organs in the male reproductive system play a major role, but what is each organs role. A list of the major organs is as follows: testes, scrotum, vas ductus, urethra, prostate gland, bulbourethral gland, penis, epidermis, and the seminal vesicles. For each of those organs comes a description, telling you what it does, and maybe some parts included in it.


The penis is one of the, if not the most commonly known male reproductive sexual organ in the body, it has one main use, for sexual intercourse. But apart from that, the penis has three components with it.

1: The root, or base, which is the part that is connected to the abdomen of the body.

2: The shaft, which is pretty self explainitory, it is the part in between the base, and glans, or head which is next.

3: The glans, or head, which as you can guess, is the tip of it all, completing the form of the penis.

4: Foreskin, which is an optional piece of skin on the body that covers the head of the penis, the process to remove the foreskin right after birth is called circumsition.


The testes, also known as the testicles, are the two egg-shaped male reproductive organs, they are located in the scrotum. The testes are what produce sperm, and give off the male hormone, testosterone.


The scrotum is a sack of skin located just below the penis, it holds the testes, it also protects blood vessels, and the spermatic cord.


The urethra is a tube that leads from the bladder to release fluids, such as urine. The urethra also releases other liquids through the penis such as semen.

Vas Ductus

The Vas Ductus is a tiny muscular tube in the reproductive system, one of them carries sperm from the epidermis to the ejaculatory duct. In each male there is a pair of these ducts.

Prostate Gland

The prostate is only located in males. The prostate gland is a walnut sized gland that grows throughout the males life, it may at some point, prevent urination by blocking the urethra. It plays a major role in assisting ejaculation of sperm during sexual intercourse.


The epididymis is a tightly massed coil of tubes which take sperm from the testes to the vas ductus. While the sperm travels through the epididymis, it matures so that it is ready to fertilize when it gets to the vas ductus.

Bulbourethral Gland

The bulbourethral gland can also be called the Cowper's Gland. What these are are two pea-shaped glands located inside of the male beneath the prostate gland. These glands add fluid during the process of ejaculation. These glands have ducts in them which allows them to pass liquid through the urethra.

Seminal Vesicles

The seminal vesicles are small sacks where seminal fluid is kept.

Article on how aging changes the male reproductive system.

In the article you would be able to read on some of the things that change in a males reproductive system as he ages. Some of the things that change or can change; one of the most common one that you may hear about is erectile dysfunction, which is where a man is not able to produce an erection as he used to. Another thing that may happen is the prostate gland can become inflamed, or become infected. Those are just a few of the things that you can read about on how things change in the male reproductive system as the male ages.

Prostate Cancer

One homeostatic imbalance is prostate cancer, which as you can guess, is located in the prostate. Prostate cancer is one of the most common types of cancer that happens to a man.

Causes: There are no real causes for prostate cancer that a doctor has found, but some things that could lead to prostate cancer is to have a cell in your prostate gland to become abnormal. Once that abnormal cell starts, it will grow and take the place of healthy cells when they die off.

Symptoms: Some symptoms of prostate cancer can include: trouble urinating, blood in urine, blood in semen, or discomfort in the pelvic region, but those are just a few symptoms. Not all cases of prostate cancer are found at early stages.

Treatment: Treatment of this cancer varies on a few factors, one of them is how fast your cancer is growing, how largely it is spreading, or even your general health. For some men, prostate cancer can be found at early stages, even if found early, some men may not need treatment, they may only have to keep an eye on symptoms to see if they get worse, or even better. Some other treatment methods include radiation therapy, hormone therapy, chemotherapy, surgery, heating or freezing prostate tissue, and immunotherapy.

Testicular Cancer

Testicular cancer is located in the testicles, which is found inside of the scrotum. Lance Armstrong is one man who is known around the world for having prostate cancer and being an athlete.

Causes: Very similar to prostate cancer, doctors are not very sure what is a main cause to testicular cancer. One thing that they think causes this form of cancer is cell abnormality, where while healthy cells spread and grow, one cell develops a problem, which then leads to testicular cancer.

Symptoms: Some symptoms of testicular cancer include the following: a lump or enlargement in one of the two testicles, a feeling of heaviness in the scrotum, a dull ache in the groin or abdomen, sudden collection of fluid inside of the scrotum. Those are just a few of the symptoms.

Treatment: There are three different ways you can treat this cancer, it depends on not only the severity of the cancer, or your overall health, but the preference of treatment. One of the most commonly picked options is surgery, where the doctor will go in and remove the testicle. Other treatment methods include radiation, and chemotherapy.

Penile Cancer

Penile cancer is one of the most rare cancers in the male, this cancer targets the penis.

Causes: Doctors and scientists believe that penile cancer comes about from penile tumors, which comes from secretions that get trapped under the foreskin of the penis if the penis is not cleaned and washed on a regular basis.

Symptoms: Penile cancer is so rare, yet the causes are similar to the symptoms, with this cancer being as rare as it is. The only real symptom is the same as the cause.

Treatment: If found at an early stage, some of the cancer patients will go to their urologist, who will give them a cream to put onto the tumor on the penis, this cream has minimal side effects. Radiation may be done if the tumor is large enough, but if the tumor is small enough, surgery to shave off small layers of skin to try and remove the tumor is what can be done.
