This seminar will explore a variety of ethical issues that arise when becoming pregnant and leading up to childhood: beginning with embryo disposition, pre-implantation diagnosis and screening, then prenatal diagnosis and genetic counseling in early pregnancy, abortion (also including access by minors to abortion and birth control), treatment of premature babies, explaining illness to children. This course will present eight cases from these respective stages (Class1-3: embryo stage, Class 4-5: embryo-fetus stage, Class 6-7 : childhood stage) and examine the cross-cultural ethical issues that arise (mainly, U.S. vs Japan). Often, patients (children/parents) and medical professionals are confronted with difficulty in dealing with these issues due to the wide range of circumstances, governments, policies, religions, and cultural values prevalent in that region. By discussing a same case with other students from different backgrounds, students acknowledge the cultural diversity in the ways of practice along with the spectrum of values that is both unique and similar to the rest of the world. These culturally sensitive findings will help in the day-to-day decisions for practitioners across a variety of nations and cultures as well as gaining respect for the universal components of biomedical ethics.
