Do you agree with the practice of using PGD to select for gender or for genetic disabilities present in the parents (for
example, deafness and dwarfism)? Why or why not? Should there be legal restrictions on PGD in the US? Why or why
not? What will be an ideal response?
ANSWER: Answers will vary.
Background:Some
countries, including Great Britain, now permit PGD screening for breast and ovarian
cancer, two genetic diseases with less than a 100% chance of occurrence. Other nations have
laws against using PGD for sex selection or for screening embryos to be donors unless they
are also screened to avoid a genetic disorder, but the United States has no such restrictions.
Perhaps the most controversial use of PGD is the selection of embryos with conditions that
most people would consider disabilities. One survey reported that a small percentage of
clinics used PGD to select embryos that would result in deaf children or children with
dwarfism. This procedure allows parents to have children who have the same physical
attributes they have, but the ethics of this practice are still being debated.
