A 17-year-old male is now in coma after suffering a heart attack when a friend jokingly squeezed his testicles. Dr. Irwin Goldstein—urologist and San Diego Sexual Medicine's director—says it's very possible to have a heart attack because the trauma can release a huge amount of adrenalin.

Yes, the testicles are exquisitely sensitive to touch and there is a huge release of adrenalin when there is excessive force applied to these organs.

Testicular pain is referred to the lower abdomen, mesenteric plexus, and causes men to stop abruptly what they are doing, lie on the ground, close their eyes and bend their knees.

A heart attack could certainly result from severe testicular pain from squeezing.
