There is no god besides me. I put to death and I bring to life, I have wounded and I will heal, and no one can deliver out of my hand. Throughout any considerations of the procreation process a Christian will stand in acknowledgment of God as the author of life. Whether we consider using birth control or fertility drugs the attitude should be one of recognizing that God creates life through us and that in the way we use birth control or fertility we are simply serving as stewards of our role in procreation. While that attitudinal awareness is important the point of specific interest here is the sanctity of human life and God's unique and exclusive right to end it.
Scripture leaves no doubt about life beginning at conception.
He saw no distinction. I should also add that the ancient Hebrew had a pretty clear understanding that conception was intimately tied to the passion of intercourse and not to some later stage of embryonic development. The point I would make here is that any procedure that would involve the careless endangerment or taking of embryonic life is unacceptable. The literature I have in the office discusses its use with surrogate parenting programs. It may not necessarily be used in all programs but if so, I would say God's Word forbids it.
