Births in Great Britain resulting from assisted conception, 1978-87. MRC Working Party on Children Conceived by In Vitro Fertilisation.

Abstract

Multiple pregnancies often result from assisted conception and are the main determinant of the outcome of the pregnancies and of the health of the children at the time of birth. Congenital malformations are comparatively rare, so larger numbers of children need to be studied before firm conclusions can be drawn. The pooling of data from different countries is recommended.
