[Genetic counseling--a qualitative element in family planning].

The number of known hereditary diseases is constantly on the increase. In Yugoslavia, about 1800 children a year are estimated to be born with severe chromosomal anomalies (about 0.5% of all newborns). Nowadays, potential parents are given much chance of controlling the biological quality of their offspring by means of genetic counselling. The authors have systematized indications for genetic counselling according to data on the pregnant woman and her sexual partner, their family history and ancestors. Also the frequency of indications for genetic counselling is assessed, ranging from about 1% of the total population of pregnant women in view of the risk of chromosomopathies to 10-15% in view of habitual abortions in the anamnesis.
