ABSTRACT
This study examined perspectives on the ethical implications of preimplantation genetic testing (PGT) among individuals who actually (not hypothetically) used or considered using PGT. Most of the prior patient-centered research on PGT ethics used qualitative designs (9 out of the 11 articles) and focused only on single gene testing. This cross-sectional study used an anonymous online questionnaire; 15 items assessed potential ethical concerns involved in PGT decision-making, including clinical indications for PGT, the greater implications of PGT for society, and unused embryo disposition. N = 207 individuals (mean female/male age 35.7/38.9 years, 21% Hispanic or non-White) who had recently used or considered using PGT for single gene (60%) or for chromosomal testing (40%) completed the questionnaire. Most respondents supported PGT screening for disease conditions with childhood or adult onset that are untreatable (64%-85% across items); most opposed PGT for trait selection (76%-81%). Most respondents agreed that PGT aids in parental decision-making (66%-67%), although some expressed concern over potential unforeseen consequences (25%-30%). Regarding disposition of embryos without known genetic abnormalities, most respondents favored freezing indefinitely (86%) or donating to another family (69%), while for embryos with genetic abnormalities, most respondents favored donating to research (78%) or destroying them (62%). Stratification by religious affiliation revealed several differences, such as less acceptance of PGT for diseases that occur in adulthood and have no treatment options among Protestants (p = .015) and greater willingness to donate surplus embryos to research among participants without a religious affiliation (p < .001). These results are limited by the relatively homogeneous sample of participants (mostly White, married, and predominantly college-educated). In summary, participants who considered/used PGT found PGT acceptable overall for screening for disease conditions; most opposed using PGT for trait selection. Our novel questionnaire provides a structured tool for assessing the ethical perspectives surrounding the use of PGT.
