ABSTRACT

Over the past two decades human procreation has become the subject of powerful medical interventions, the two most prominent being assisted reproduction and prenatal diagnosis. Preimplantation diagnosis (PID) may be regarded as the culmination of this development. In order to recognise or exclude genetic disorders it combines in vitro fertilisation (TVF) with the molecular or cytogenetic analysis of a sample from the very early conceptus (Handyside 1993).
