Conception, Pregnancy and the Beginning of Life

Thanks for your reply. If I understand correctly, then, before 40 days one can talk about life of the embryo/fetus from a biologic but not a halachic perspective? This raises a second question — have the rabbis discussed the status of Adam after he was fashioned but before God breathed life into him?
