Abstract

We shall have to evolve problem-solvers—galore since each problem they solve creates ten problems more— Piet HeinThe new reproductive technologies, especially in vitro fertilization, have extended the possi- bilities of assisted reproduction to the benefit of the childless couples. At the same time these technologies and their added techniques, however, have fragmented reproduction and exposed the human egg to intervention yet unknown:The embryo may be divided into several embryos; may be sold; donated; cryopreserved; borne by another woman and returned; or used for research;Genetic parentage may be present without sexual intercourse, may be different from social parentage and the natural time-span between fertilization and birth may be interrupted.
