N44: Torsion of testis

Torsion of the testis is a medical emergency that involves the twisting of the spermatic cord, which carries blood to the testes. This twisting results in decreased blood flow, leading to sudden and severe pain in the affected testicle. Additional symptoms can include swelling, nausea, and abdominal pain. If not promptly treated, torsion of the testis can result in damage or loss of the testicle due to lack of blood supply. This condition is more common in boys and men under 25, but it can occur at any age. While the exact cause is not known, some men may have a higher risk due to genetic factors, trauma to the scrotum, or rapid growth during puberty. Torsion of the testis can occur spontaneously or after physical activity.
