A variety of things can cause pain in the scrotum, the pouch-like structure at the base of a boy's penis.
The scrotum holds the testicles (the organs that produce sperm). It also holds the epididymis and the vas deferens, which are tubes that sperm travel through before leaving the body.
Things that can cause scrotal pain include:
Testicular torsion, which is when the spermatic cord that provides blood flow to the testicle rotates and becomes twisted, usually due to an injury or medical condition. This cuts off the testicle's blood supply and causes sudden and severe pain and swelling. Testicular torsion is a medical emergency that usually requires immediate surgery to save the testicle.
Boys and teen guys can sometimes experience scrotal pain that doesn't always come from the scrotum itself. Sometimes it comes from a pulled muscle or tendon near the scrotum, or from another part of the body, such as the lower back or belly.
