[Genetic counselling (results of ten years experience). IV. Attitude of persons seeking counselling and reliability of the counsel (author's transl)].

The authors, from their personal experience arising from 766 consultations, show that the percentages of marriages or procreations in subjects themselves suffering from a disorder, or with affected relatives, are independent of the risk estimated for their offspring. The procreation rate in couples with affected children is lower in high risk cases and depends also on the family composition. It appears that this procreation is voluntary in the great majority of cases because there were very few terminations of pregnancy among the couples seen before procreation. The estimated risks correspond to the risks observed but the authors insist that there is a relatively high proportion (4.4 per cent) of children born with a disorder different from that which motivated the consultation.
