Why is that during somatic cell nuclear transfer the embryo is never implanted into the uterus?
Never is a powerful word. Wasn't Dolly the sheep created this way?
Maybe I ought to add to this. We live in a world that under social and legal mores we reproduce things from gametes, in fact, in many places, including Texas, it is illegal (and some say immoral) to reproduce with cells other than gametes. So placing the somatic cell nucleus into the uterus will be akin to "creating" life, which is illegal. Yes, Dolly the sheep was cloned this way, but not in Texas.
