Why does a kick to the groin hurt so much?

In this world, there is probably only one thing that the Adam fears most more than anything else: being an easy target from a killer ball kick that flies into the groin, which makes the testicles sore for mercy.

After finished moaning in pain, have you ever wondered why the pain can be so unbearable that it often makes men cry?

What causes the testicles to hurt so badly when they are hit?

The testicles are known to be sensitive. That's because this vital part is planted with thousands of sensory nerves more than any other part of the body. These nerve endings, called nociceptors, act as safety mechanisms and are tasked with alerting the brain to changes in temperature, vibration, and pressure that can damage the body through the sensation of pain.

When your testicles are kicked, these clusters of nociceptors fire up simultaneously to send waves of pain signals to the brain. Then the brain responds to these signals by releasing physical pain-inducing chemicals, which make you react quickly to the impact - either by curling up in pain or screaming.

And unlike most of our bodies which are protected by a layer of muscle, bone, or cartilage, the testicles (scrotum) lie just outside the body cavity. This leaves your testicle in a very vulnerable position to direct physical impact. The testicles are just a pair of tiny glands that are protected by the thin skin of the testicles, so they are forced to absorb all the force of impact alone without a layer of muscle and so on to counteract the hard impact.

The pain of the testicles when kicked can cause headaches, stomach pain, and even vomiting

Kicks to the groin not only cause the testicles to hurt, they can also cause a man to experience pain in the abdomen - even though the impact does not occur directly on that part of the body.

Although their appearance is dependent, the testicles initially form in the lower abdomen near the waist, near the stomach and kidneys. From there, the testicles descend towards the testicles while pulling their sensory nerves down. So when you get a free kick right in the groin, the impact will travel from your testicles to the top of your body through the sensitive nerves that run between them.

You may also feel severe nausea or even vomit when you kick the testicles. The testes are connected to the vagus reflex, which sends large amounts of nerve signals from the testes to the spinal cord and brainstem to activate the nausea and vomiting centers in your brain. But whether you vomit or not after being the victim of a lethal kick will depend a lot on how tolerant you are to the pain.

Not infrequently, many men experience severe headaches when they are hit by a kick in this vital organ. This is because the brain also releases endorphins in response to pain, which depletes some of the oxygen present in the brain - making the head achy and sore.

A very bad kick to the testicles can leave a man infertile

If you like playing soccer, watch out. One-on-one, free kicks to the groin can not only make testicles sore, but also threaten your chances of having children in the future.

Basically, the sensitivity of the testicles to heat, vibration, and pressure solely aims to protect sperm health. This is why your testicles are so sensitive to pain, even the slightest pain. The quality of the sperm that is hit by the extraordinarily hard impact of a kick received by your groin can be severely damaged, which in extreme cases can leave you infertile.
