Background: When children suffer severe genetic disorders and require stem-cell transplantation, compatible donors may be unavailable. Then preimplantation genetic diagnosis (PGD) may identify some whose gestation and birth would produce unaffected newborns, and placental and cord blood from which stem-cells compatible for implantation in sick siblings can be derived. Discarding of healthy but unsuitable embryos and choosing one for the siblings’ end is the matter of ethical concern. This study was performed to evaluate the different views for PGD.

 Methods: A 5 question questionnaire was used, that we could understand the degree of their opinion with a score (-2,-1,0,+1,+2). This questionnaire was distributed among ordinary people, university students (not medical), medical university students, diagnosed patients (AML, CML, NHL, and HL), teachers of religion and educational hospital attending. Number and percentage of each score in each group was calculated.

 Findings: Among 502 ordinary people the mean score was -0.66, this rate was +0.96, +1.52, 0.02, -0.74, +1.02 among non medical university students, medical students, patients parents, religion teachers and attending respectively. Religious reasons (42%) among negative opinions and humanity reasons (53%) among positive opinions were the most.

 Conclusion: The highest mean score belonged to medical students and the lowest was religion teachers’. In a religious country religion is influencing people’s opinions and this should be of a great importance. But parents with a patient child shouldn’t deprive a method may change their lives and the child’s life forever.
