Preimplantational ectogenesis. Science and speculation concerning in vitro fertilization and related procedures

In recent years, technical advances have made preimplantational ectogenesis (in vitro maturation, fertilization and early embryonic development) more than a theoretical concept. Such procedures hold great promise in medical research. However, despite our newly-acquired skills in tissue culture and microsurgical manipulation, and contrary to many sensational articles in the lay press, it is not likely that preimplantational ectogenesis will soon attain wide clinical use in humans. Adverse societal attitudes, based largely upon moral and ethical dilemmas, will probably combine with still-unresolved technical difficulties to restrict the clinical applications.
