In this paper we argue that the human form should be seen to exist, in a longitudinal way, throughout the continuum of human growth and development. This entails that the moral value of that form, which we link analytically to the adult, interacting, social and rational being, attaches to all phases of human life to some extent. Having established this we discuss the consequences it has for the moral status of the human embryo. We then apply this argument, and the (...) resulting moral status, to the area of reproductive technology. In doing this we show that there are certain regulations and controls which ought to apply to the use of these infertility treatments. (shrink)
