One of the great success stories of British science in the last 30 years was the introduction of In Vitro Fertilisation by Steptoe and Edwards in 1978. They should have won the Nobel Prize. Around 3% of babies are now born after IVF. Testing of and experimentation on early human embryos offers great prospects for improving not only the health of the next generation but how well their lives go. Today, a wide variety of genes which cause or contribute significantly to disease can be tested. Soon, it will be possible to test for all the genes an embryo has and choose embryos which start life with the least prospects of disease and greatest range of talents, abilities and capacities. And IVF has allowed individuals and couples to have children in new ways, expanding procreative liberty. Experimentation on embryos is yielding important knowledge of human development and contributing to the development of regenerative medicine, or stem cell therapies.
Assisted reproduction, including embryo testing, and research involving the embryo has been controlled by the Human Fertlisation and Embryology Authority (HFEA). I recently wrote an evaluation of the performance of the HFEA. I argued that the HFEA was set up on the wrong premise: the embryo was said to have a special moral status. Regulation should be set up on the basis of preventing real, tangible and direct harm. Destroying some embryos but not others is not an example of preventing harm. Secondly, it has operated to enforce public morality, imposing moralism not preventing harm. This was kind of objectionable moralism that was employed by Lord Devlin to justify a ban on homosexuality. Thankfully, HLA famously disposed of that bad justification, at least in the case of homosexuality. Moralism, however, has been alive and well in the case of reproduction.Read More »Moralism and Reproduction: Ten Infringements of Liberty
