Things that can go wrong with the male reproductive system
Boys may sometimes experience reproductive system problems, including:
Disorders of the scrotum, testicles, or epididymis
Conditions affecting the scrotal contents may involve the testicles, epididymis, or the scrotum itself.
* Testicular trauma. Even a mild injury to the testicles can cause severe pain, bruising, or swelling. Most testicular injuries occur when the testicles are struck, hit, kicked, or crushed, usually during sports or due to other trauma. Testicular torsion, when one of the testicles twists around, cutting off its blood supply, is also a problem that some teen males experience, although it's not common. Surgery is needed to untwist the cord and save the testicle.
