Silent Birth?

I've been reading a lot about the Scientology ideal of a "silent birth." Everyone in the birthing room is supposed to be quiet, and the woman is supposed to refrain from any expressions of pain and pain medication.
I can't even believe the ego a man, in this case L. Ron Hubbard (not an obstetrician, or good writer), would have to possess to write a manual for a proper labor and delivery. That would be like me or any woman telling a man how he should react to getting smacked in the crotch, only much, much worse.
