After smacking his scrotum into a bathtub, a teen presented to his GP.

The 16-year-old, who had a history of retractile testes, had fallen in the bath the previous day after which he experienced severe right testicular pain and nausea.

The GP noted a tender right scrotum with elevation, while palpation revealed induration and tenderness of the superior portion of the right testicle.

But there was a twist in the case.
