Maroonsaint, I know it's you! Is this yet another ruse to get guys to send pictures of their junk? The normal number of testicles is actually five. Two obvious ones in the sack, another two stored in the body cavity, ready to descend if the external ones are lost, and another proto-testicle will take five months to a year to develop and drop if the second batch is lost. Anyone who has speyed a pet chimpanzee will know this. Learn some basic biology!
