Why Do Testicles Hang Outside The Body: Why there is severe pain even after a minor injury and why the testicles remain outside the body, these questions often come to people’s mind. 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 muscle located beneath the penis. There are two oval glands inside it, which work to produce sperm and secrete hormones like testosterone.
Why are they outside?
According to clevelandclinic, a website that provides information about health, the testicles are outside the body because they require a temperature slightly lower than normal body temperature. Sperm formation occurs properly only when the temperature remains a few degrees lower than the body temperature. The scrotum works like a climate control system. The cremaster muscle present in it moves the testicles closer or away from the body as per the need, so that the temperature remains balanced. For this reason, nature has made arrangements for them to hang outside, not inside the stomach.
Why does a minor injury cause pain?
According to the report of Medicalnewstoday, now the question arises that why does a minor injury cause such severe pain. The main reason for this is the maximum tension of the nerves. The testicles have very dense and soft nerve endings. Due to so many nerves in a small part of the body, even a slight shock turns into severe pain. Apart from this, this part is external and is not protected by bones or thick muscles, hence the impact of injury falls directly on these.
How is protection done?
However, nature has also provided some safety measures. The skin of the scrotum is flexible, the fibrous layer tunica albuginea is present inside and there is slight movement in the testicles, so that they can tolerate shocks to some extent. But this protection does not completely protect from pain. Many times, after injury to the testicles, pain is also felt in the stomach or lower part. This is called referred pain. Actually, during fetal development, testicles are initially formed inside the abdomen and later descend downwards. For this reason, some of their nerves remain connected to the stomach area. When an injury occurs, the brain receives a signal, but it does not always recognize the exact location, which can lead to stomach pain or nausea.
