Things you need to know about the scrotum

How do you feel about the scrotum, the organ in your body that is connected to your genitals? You may not have thought much about it. But, as a man, this organ called the scrotum is very important for your reproductive health and overall health. So today, let's learn everything about it very simply, as if we were talking to a friend.

Simply put, what is this scrotum?

The scrotum is a thick, leathery sac that hangs below your penis, between your thighs. This sac protects two of the most important organs in your reproductive system, the testicles .

These two testicles are where sperm is produced and stored. They also produce the male hormone testosterone .

You might be wondering why this is located outside the body. There is a specific reason for this. For the sperm production process to take place properly, it needs to be slightly cooler than the body's normal temperature. So the testicles are located outside the body to provide that necessary cool environment. It works like a climate control system.

Main functions of the testicle and its parts

The main function of the scrotum is to protect the testicles from external dangers and to maintain the proper temperature required for sperm production.

Imagine, on a cold day, you might feel your testicles shrink and move closer to your body. On a hot day, they expand and move away from your body. This happens automatically. Special muscles in the testicles help with this.

Now let's look at the main parts inside the testicle.

  • Testicles: These are the main parts. They produce sperm and the hormone testosterone.
  • Epididymis: At the top of each testicle is a tightly coiled tube. This is what we call the epididymis. Sperm produced in the testicles reach this tube for maturation and storage.
  • Spermatic cord: This contains the blood vessels that supply blood to the testicles, the nerves, and the tube that carries sperm (vas deferens).
  • Cremaster muscle: This muscle helps to bring the testicles closer to and away from the body. It regulates temperature. When the testicles feel cold, this muscle contracts and brings the testicles closer to the body's warmth.

Common conditions affecting the testicles

Like any other organ, the testicles can be affected by a variety of conditions. Some of these can be serious conditions that require emergency treatment. Therefore, it is very important to be aware of this.

Condition Simply put, what is it?
Inguinal hernia A piece of tissue, such as the intestine, in the abdomen pushes through a weak spot in the abdominal wall towards the testicle.
Hydrocele A swelling of the scrotum that fills with fluid. This is most common in young children, but it can also occur in adults.
Varicocele Swelling or enlargement of the veins ( blood vessels) in the testicles, similar to the veins in the legs.
Spermatocele A fluid-filled cyst or sac-like mass on the epididymis.
Testicular torsion This is a very serious and urgent condition. The testicle is twisted around the cord that connects it, cutting off its blood supply. If this is not treated immediately, it can cause damage to the testicle.
Epididymitis The epididymis, the tube that carries sperm, becomes infected and swollen.
Orchitis Swelling or infection of one or both testicles. Often associated with viral infections such as mumps.
Testicular cancer The growth of cancer cells in the tissues of a testicle.

Watch out for these symptoms! When to see a doctor

If you notice any unusual changes in your testicles or the surrounding area, don't ignore it. If you have one or more of the following symptoms, be sure to see a doctor.

Remember, sudden, severe pain in the testicle is a medical emergency . In such cases, you should go to a hospital's Emergency Department (ETU) immediately.

Symptom What you can feel
Pain Pain can range from mild to severe, unbearable pain, especially pain that starts suddenly or lasts for a long time.
Swelling, redness Swelling of the testicle or part of it, pain when touched, and redness of the skin.
Lumps or sores A new lump or sore on the testicle or skin.
Feeling heavy Feeling of unusual heaviness or drooping in the scrotum.
Other features Frequent need to urinate, blood in the urine or semen, unusual discharge from the penis.

Do these things to keep your testicles healthy.

There are a few simple things you can do yourself to take care of your testicular health.

  • Do a monthly self-exam: At least once a month, like while you're taking a shower, gently examine your testicles with your fingers. Look for any new lumps, swelling, or tenderness. Tell your doctor if you notice any changes.
  • Stay clean: Bathe daily and wash your genital area thoroughly with soap. This will reduce the risk of skin infections.
  • Keep the area dry: After bathing, dry the genital area thoroughly. Moisture can lead to fungal infections.
  • Avoid tight clothing: Wear loose, airy underwear and pants. Tight clothing can increase the temperature of the testicles and affect sperm production.
  • Safe sex: Avoid unprotected sex. Using a condom can protect you from sexually transmitted infections (STIs).
  • Be careful when removing hair: If you need to remove hair in that area, it is better to cut it with a trimmer than with a razor. This can minimize skin allergies and injuries.

Treatment options vary depending on the condition. Some conditions, such as hydrocele, may not require treatment unless there is pain. However, conditions such as inguinal hernia and testicular torsion may require surgery. Antibiotics may be given for infections. The doctor who examines you will decide which treatment is best for you.

Take-Home Message

  • The main function of the scrotum is to protect the testicles and maintain the correct temperature needed for sperm production.
  • If you notice pain, swelling, a lump, or any other unusual change in your scrotum or testicles, don't ignore it.
  • It is a very important habit to perform a self-examination once a month.
  • If you experience sudden, severe pain, go to a hospital immediately as it may be a medical emergency.
  • Many problems can be prevented by good personal hygiene, wearing loose clothing, and practicing safe sex.
  • Never delay seeking medical advice out of shame or fear. Your health is the most important thing.
