Psychological implications and acceptability of preimplantation diagnosis.

The aim of this study was to ascertain the degree of acceptability of preimplantation diagnosis with blastocentesis in 180 women at risk for beta-thalassaemia awaiting chorionic villus sampling (CVS). The women were asked to fill in a questionnaire some days before sampling. All women who had had previous therapeutic abortion found blastocentesis acceptable. Only 30% of women who had not had previous therapeutic abortion chose blastocentesis, whilst 25% of primigravid women opted for blastocentesis. From these preliminary data it seems that obstetric experience is an important factor in the reproductive choice of women at high genetic risk.
