Swollen testicles can be caused by various factors, including injury, infection, inflammation, or a testicular tumor. Here are some of the most common causes of swollen testicles:
-
Hydrocele: A hydrocele is a collection of fluid that builds up around a testicle, causing a significant amount of scrotal swelling and discomfort. It is often harmless and more common in infant boys, but it can occur in adult men too.
-
Infection: The testicle and epididymis, the part of the testicle that stores sperm, can sometimes become infected, causing pain and swelling that starts quickly and gets worse. Orchitis is inflammation of one or both testes and is usually caused by either bacterial or viral infection.
-
Varicocele: A varicocele is a collection of widened veins on the outside of a testicle that can affect fertility in some men.
-
Trauma: An impact or other injury can cause the testicle to swell and be painful.
It is important to see a doctor if you have swollen testicles, especially if you have severe pain, fevers and chills, blood in your urine, or difficulty peeing. Applying an ice pack and taking a pain reliever like acetaminophen can help ease the discomfort.
