Infertile men who carry a chromosomal translocation can be successfully
treated with intracytoplasmic sperm injection (ICSI). However, such
treatment carries a risk that a pregnancy with an abnormal karyotype will
be induced. While in all previously published cases the outcome was
favourable, we here report the first instance of a parental reciprocal
translocation leading to a chromosomally unbalanced ICSI pregnancy. The
fetus, one of a pair of dizygotic twins, was found to have trisomy for the
short arm of chromosome 9. The parents opted for selective abortion of the
affected twin.
