Causes of Testicular Pain: The testicles are one of the most sensitive organs in the human body. Let us explain why they hang out and why even a minor injury can cause so much pain.

Why are the testicles outside the body?

Why Do Testicles Hang Outside The Body: Why does a slight injury cause severe pain, and why do the testicles remain outside the body? This question often comes to people's minds. Actually, this part of the male reproductive system is very sensitive and has a special structure. The sac that surrounds the testicles is called the scrotum, which is a strong but flexible structure made of skin and muscles located below the penis. Inside it are two oval glands, which work to produce sperm and secrete hormones like testosterone.

Why are they outside?

According to the health information website clevelandclinic, the testicles are located outside the body because they require a temperature slightly lower than normal body temperature. Sperm production can only occur properly when the temperature is a few degrees lower than normal. The scrotum functions as a climate control system. The cremaster muscle in the scrotum moves the testicles closer to or further away from the body as needed, maintaining a balanced temperature. This is why nature has designed them to hang outside the abdomen, not inside.

Why does a minor injury cause pain?

According to a report in Medicalnewstoday, the question arises as to why even a minor injury causes such intense pain. The main reason for this is the high concentration of nerves. The testicles contain very dense and delicate nerve endings. Because of the large number of nerves in such a small area of the body, even a slight shock can result in severe pain. Furthermore, this area is external and not protected by bones or thick muscles, so any injury directly impacts it.

How is prevention done?

However, nature has provided some protective measures. The skin of the scrotum is elastic, the tunica albuginea is present inside, and the testicles have slight motion, allowing them to absorb shock to some extent. However, this protection does not completely prevent pain. Sometimes, after an injury to the testicles, pain is felt in the abdomen or lower back. This is called referred pain. In fact, during fetal development, the testicles initially form inside the abdomen and later descend downward. Because of this, some of their nerve connections remain connected to the abdominal region. When an injury occurs, the brain receives a signal, but it cannot always identify the exact location, which can cause abdominal pain or nausea.
