Dear Sir,
There has been considerable debate and controversy about genetic risks associated with intracytoplasmic sperm injection (ICSI) (Martin, 1996
; Persson et al., 1996
). As well as concerns about the increased frequency of the cystic fibrosis transmembrane regulator mutations and Y chromosome deletions in infertile males, there is also mounting evidence of increased risks for chromosomal abnormalities following ICSI. Studies of infertile men have repeatedly demonstrated
