The placenta is filled with progesterone--the hormone that allows a healthy pregnancy to continue. Getting past the sickenss of the cannibalism of his child's source of nutrients during this pregnancy (wouldnt' a psychologist have fun with that!), he would also be getting a HUGE dose of progesterone.
So presumably he could have a healthy pregnancy if he wanted.
All right...

Progesterone in large doses will cause sterility in men (Chemical castration) - Go ahead Tom, eat it... we don't need you to reproduce anymore...
