[Infertility and congenital malformations--secondary publication]

Studies indicate that children born by infertile couples have a higher frequency of congenital malformations. This may be a side effect of infertility treatment or may be caused by the underlying disease. We compared children of couples who received infertile treatment with children of infertile couples who conceived without treatment after more than 12 months of trying. We found no differences in the frequency of congenital malformations in the 2 groups, which may indicate that the underlying disease is more important than the treatment.
