Prayers of the faithful: that life be cherished "from birth until natural death"

Today during intercessions at mass, the prayers of the faithful included "that all human life be cherished, from birth until natural death." I don't remember the verbiage I'm used to exactly but I'm certain that it was always something very similar like "for all human life, from conception until natural death" - conception, not birth.

Is there a reason for this change, is it coming down from higher levels for a good reason I don't know, is it the priest's preference? It stood out as troubling - on its face it's still a beautiful petition, but feels sanitized to avoid unpopular political connotation, at the expense of doctrine - but I'd rather not jump to conclusions here.
