The most common cause of viral orchitis is the mumps. Mumps is a viral childhood disease that’s rare in the United States due to effective immunization programs. The Mayo Clinic estimates that 33 percent of men who get the mumps as teens also develop orchitis.
Testicular pain is a discomfort felt in the testicles (testes) or scrotum. Causes of testicular pain, discomfort or swelling may be very serious and require prompt medical treatment, like testicular torsion, which is a medical emergency. that requires surgery.
During testicular torsion a testicle rotates, twisting the spermatic cord that brings blood to the scrotum. The reduced blood flow causes sudden and often severe pain and swelling. Having testicles that can rotate in the scrotum is a trait inherited by some males.
The scrotum is a skin-covered sac that holds your testicles. It also contains the arteries and veins that deliver blood to the reproductive glands. A vein abnormality in the scrotum may result in a varicocele. A varicocele is an enlargement of the veins within the scrotum. These veins are called the pampiniform plexus.
