Familial testicular torsion in three consecutive generations of first-degree relatives.

We report the first and largest family with testicular torsion in three consecutive generations affecting four first-degree relatives. The incidence of familial testicular torsion is under reported in the literature. We recommend eliciting family history in evaluation of acute scrotum, as a useful adjunct for clinical decision making. In families with a strong predisposition to testicular torsion, management should include family counseling about the significant risk of occurrence of this condition.
