Which of the following is a potential complication of untreated testicular torsion?

Testicular torsion is a surgical emergency that occurs when the spermatic cord becomes twisted, cutting off the blood supply to the testicle. If this condition is not treated promptly, it can lead to the testicle becoming necrotic due to lack of blood flow. This necrosis can result in significant damage, including the loss of the testicle.

Infertility is a potential complication of untreated testicular torsion because testicular tissue is vital for sperm production. If one or both testes are compromised or removed due to torsion, this will directly impact a man's fertility. Additionally, the severity and duration of the torsion play crucial roles; the longer the testicle is deprived of blood flow, the higher the risk of irreversible damage and potential loss.

Conditions like benign prostatic hyperplasia, inguinal hernia, and hydrocele, while related to the genital and urinary systems, do not stem from untreated testicular torsion or directly relate to its consequences. They represent different pathologies and are not immediate complications associated with the lack of treatment for testicular torsion.
