you are missing the point; the issue is one of semantics ie whether the popular conception of conception (aheh heh) ie egg+sperm=conception is correct. Medically speaking, it appears not to be.

Perhaps the proper slogan should be "Life begins at fertilisation!"

I won't surrender the term "conception" that easily. Words have power; I don't work for the authors of politically correct medical dictionaries.
