Well, I suppose it’s how you define regeneration:
“In biology, an organism is said to regenerate a lost or damaged part if the part regrows so that the original function is restored.”
http://en.wikipedia.org/wiki/Regeneration_(biology)
It seems to be a function of the amount and type of damage. Even in peyronie’s disease where there appears to be some type of injury process ~15% resolve spontaneously. You can check it for yourself on the Internet or ask your doctor. If you get a cut, dots, etc or even minor nerve injuries, etc. as many have on this forum, they do heal. So, I’m not sure how anybody can say that penis tissue doesn’t regenerate, unless they mean the more severe form of damage. Just my opinion.
