title: Perspectives of couples with high risk of transmitting genetic disorders.
abstract: OBJECTIVE
  To investigate the preference for preimplantation genetic diagnosis (PGD) as an alternative to prenatal diagnosis (PND) in a large group of couples representing a wide array of genetic disorders. We also investigated the couple's familiarity with PGD and presented time trade-off scenarios for PGD versus PND, as PGD treatment is regularly accompanied by waiting lists.
  
  
  METHODS
  Questionnaire study.
  
  
  METHODS
  Patient organizations representing genetic disorders.
  
  
  METHODS
  A total of 210 couples carrying genetic disorders.
  
  
  METHODS
  Preference for PGD or PND and familiarity with PGD in carrier couples.
  
  
  RESULTS
  Fifteen organizations representing 38 genetic disorders agreed to participate. Nine hundred eighty-three couples responded. In total 210 couples were in their reproductive years (women 18-40 years) and had a desire to conceive. Ninety couples (42%) had never heard of PGD. After they were informed, 127 couples (60%) wanted to have diagnostic testing (PND or PGD) performed. Ninety-four (74%) of these couples preferred testing with PGD. When no waiting list was used 102 couples (80%) preferred PGD. With a 2-year waiting list for PGD, 58 couples (46%) would opt for PGD.
  
  
  CONCLUSIONS
  Many carrier couples are unaware of the existence of PGD. When informed, most couples prefer PGD more than PND. The preference for PGD decreases with longer waiting lists.
