PSYCHOLOGICAL-STUDY OF IN-VITRO FERTILIZATION-EMBRYO TRANSFER PARTICIPANTS ATTITUDES TOWARD THE DESTINY OF THEIR SUPERNUMERARY EMBRYOS

Objective: To study the motivations underlying IVF-ET participants' ch oice to donate or destroy their supernumerary embryos. Design: Couples ' opinions are studied through a questionnaire and a psychological int erview. Participants: Two hundred couples about to undergo NF-ET. Sett ing: The fertility unit of an academic hospital. Main Outcome Measures : Couples' choice for supernumerary embryos' destiny; opinions on embr yo status, on importance of genetic lineage in the filial bonding, on gamete donation, and on multiple pregnancy risk. Results: Donation is the most frequent choice but destruction is tolerated by almost all th e couples (92%). Couples considering the embryo as a child choose dest ruction as frequently as donation but refuse experimentation on the em bryo. Donation is highest among couples who stress education more than genetic lineage in parental bonding. This is confirmed by the choice of the couples requiring donor gametes. Couples express differing atti tudes toward risks of twins and risks of triplets: twins are much more desired than triplets, which are frequently refused. Conclusions: Cou ples' opinions on the respective importance of genetic lineage and edu cation in defining parental bonding are more determinant in their deci sion to destroy or to donate their supernumerary embryos than their op inions on the in vitro embryo status, which only determines their atti tude toward experimentation.
