What Is Testicular Torsion
According to my.clevelandclinic.org, "Testicular torsion is a painful condition where the testicle twists and loses its blood supply. It requires emergency care. If the blood supply doesn't return quickly (within six hours), a healthcare provider may need to surgically remove the testicle."
The website adds that testicular torsion is rare, affecting about one in 4,000 men under age 25. "It's usually a spontaneous event, meaning it occurs without any apparent cause. It almost always affects only one testicle. It more commonly affects the left testicle than the right," the report noted.
I just added the above info, as one of the cricketer needed to undergo this emergency surgery recently.
