Social conditions of children born after artificial insemination by donor.

Few objective data are available concerning the social conditions of children born after artificial insemination by donor (AID). We have studied 341 consecutive AID children born of 261 women during a 13-year period. Data from hospital archives were compared with information from the National Register of Norway. The parameters studied included age-relations of parents and offspring, sex- and age-relations between siblings as well as the divorce rate in AID families. Median maternal age at birth of the first AID child was 30 years. Forty-three percent of AID children were born in families that already had children or that later obtained an additional child; the majority of these siblings were conceived by AID. Mean age difference between the closest related AID siblings was three years. Six of the 261 AID families were split by divorce during the study period. The results only reflect such information as can currently be obtained with maintenance of the promise of secrecy.
