by Dr R. G. Edwards
Five years ago the first test tube baby was born: now over 300 babies have been conceived in vitro. The technique was pioneered by physiologist Robert Edwards and obstetrician Patrick Steptoe. In the early days their efforts were considered unethical, even immoral, possibly dangerous. Now their methods have worldwide clinical application in the treatment of infertile couples. Dr Edwards reflects on the changes in attitude and examines the implications of new techniques such as embryo freezing and egg donation and experimentation on the human embryo.
