Intervention(s): Right and left scrotal temperature and LC and lap pad temperatures were recorded during three
separate 60-minute sessions using a working LC in a laptop position: session 1, sitting with closely approximated
legs; session 2, sitting with closely approximated legs with a lap pad below the working LC; and session 3, sitting
with legs apart at a 70
