title: A burgeoning science of embryological genetics demands a modern ethics.
abstract: This brief article discusses the nature of recent scientific advances in reproductive biomedicine and genetics, their moral implications and their effects on society. The pace of research has amplified exponentially, leading society into situations incomprehended by our ancestors. Early studies on reproductive biology in animals, and clinical methods such as artificial insemination by donor spermatozoa, were introduced several centuries ago and led to prolonged ethical disagreements. The 20th century witnessed the introduction of controlled ovulation in laboratory animals, the fertilization of the oocyte and preimplantation embryology in mammalian species. The second half of this century produced an avalanche of knowledge on genetics, developmental biology, the fertilization of the human oocyte in vitro, test-tube babies, preimplantation genetic diagnosis, designer babies, stem cells and a deeper understanding of molecular differentiation in the human embryo. The ethical and legal aspects of these items have led to intense debates on their rights and wrongs. The future may have even more bizarre possibilities such as producing medicines in cow's milk or trees and delaying death for many years.
