The telly host has been practicing a dangerous lift which will see his professional partner's skates come too close to comfort to his crotch.
The Sun reports that Sam has asked for extra 'protection' ahead of Sunday's show, after Jennifer Ellison's misplaced skate saw her injure herself last week.
Sam joked that messing up the lift with pro Alexandra Schauman could even stop him from having kids in the future.
He said: "It's terrifying. We don't want 'little Sam' getting injured."
Dancing On Ice 2012 continues this Sunday night on ITV1 with the Ultimate Skills Test.
