  1. Discussions Worth Sharing Technology. Eugenics. Design Designer BabiesThe Future of Reproductive Technology

  2. Outline Discussions worth Sharing • Background • Who is it for • Canadian statistics and regulations • Discussions • Reflections • Future directions • Summary

  3. Objective Discussions worth Sharing • General understanding of preimplantation genetic diagnosis (PGD) technology • Gain a wider perspective on cultural, religious and social implications • Think actively, discuss openly, participate!

  4. Background Discussions worth Sharing Designer Baby – “a baby whose genetic make-up has been selected in order to eradicate a particular defect or to ensure that a particular gene is present”

  5. Background Discussions worth Sharing Preimplantation Genetic Diagnosis (PGD) • Assisted human reproductive technology • Screening of embryos for genetic abnormalities prior to transferring to the uterus • In vitro fertilization consists of: 1) Ovarian stimulation 2) Egg retrieval 3) Egg fertilization 4) Embryo development 5) Embryo transfer

  6. Who? Discussions worth Sharing • Individuals or couples who are at risk to pass on a condition that is the result of a variant in a single gene • Individuals or couples with a chromosome condition, or who have had a previous child with a chromosome condition • Women who are at an increased risk to have a child with a chromosome condition due to their age

  7. Canadian Statistics - 2010 Discussions worth Sharing • 22 769 patients underwent in vitro fertilization over the past 5 years • 61% of fertility clinics responded (17 out of 28 clinics) • 6 performed embryo biopsy on site • 7 referred to other units in Canada • 3 referred to units in U.S. • Majority do not offer PGD due to: • Lack of resource/staff/money/expertise • No market demand • Not convinced it would yield accurate diagnosis

  8. Regulations Discussions worth Sharing • Assisted Human Reproduction Act (2004) • Prohibited Activities • Create a human clone • Create an in vitro embryo for any purpose other than creating a human being • Maintain an embryo outside the body after 14 days of fertilization • Alter the genome of a cell of a human or in vitro embryo • Gender selection for non-medical reasons

  9. Discussions Controversies

  10. Discussions worth Sharing

  11. Discussions Discussions worth Sharing • Selecting for a disability “Being deaf is not about being disabled, or medically incomplete - it's about being part of a linguistic minority. We're proud, not of the medical aspect of deafness, but of the language we use and the community we live in.”

  12. Discussions worth Sharing

  13. Discussions Discussions worth Sharing • First born child: 76% have no gender preference • More than one child: 30% want equal number of girls and boys, and 58% have no preference • Using technology: 92% against it • Surveyed among pregnancy women: 58% had no gender preference • 234 surveyed: • 39% have no preference • 39% prefer a girl • 22% prefer a boy • Couples undergoing fertility treatment:40% would like to select the sex of their baby

  14. Discussions Discussions worth Sharing • Adam Nash • One of 15 embryos • Saved his sister suffering from Fanconi’sanaemia • Great achievement or unethical?

  15. Discussions worth Sharing Reflection Religious, Cultural, Societal Impacts

  16. Religious Impacts Discussions worth Sharing • Dignitas Personae • “Preimplanation diagnosis…constitutes an act of abortion... By treating the human embryo as mere ‘laboratory material’, the concept itself of human dignity is also subjected to alteration and discrimination…Such discrimination is immoral and must therefore be considered legally unacceptable…”

  17. Cultural Impacts Discussions worth Sharing • India • Prefer boys • China • Country side • Prefer boys

  18. Social Impacts Discussions worth Sharing • Socioeconomic disparity • Discrimination • Social activists • Disability activists • Eugenics – “the science of improving a population by controlled breeding to increase the occurrence of desirable heritable characteristics”

  19. Future Directions Discussions worth Sharing • More research, increased market demand, increased access to screening • More on-site PGD • More will choose PGD over other methods • When should it be refused? • What to regulate? • Should government provide funding?

  20. Summary Discussions worth Sharing • Science and technology is always evolving • No right or wrong views • Religious, cultural, societal influences • Keep an open mind “The important thing in science is not so much to obtain new facts as to discover new ways of thinking about them.” - Sir William Lawrence Bragg More information at: http://futurebabies.weebly.com
