A total of 150 infertile couples underwent chromosome analysis and genetic
counselling before intracytoplasmic sperm injection (ICSI). Chromosomal
abnormalities, including low-level sex chromosome mosaicism, were detected
in 12% of the men and an unexpectedly high 6% of the women. Chromosomal
abnormalities included gonosomal mosaicism in 13 cases, Robertsonian
translocations in four males, autosomal reciprocal translocations in five
cases, reciprocal translocation involving a sex chromosome in one case,
inversions in three cases and a marker chromosome in one male. Chromosomal
variants found in 11 women and 13 men were not included in the above
percentages. Couples with a chromosomal aberration in one partner received
a second counselling. The different aspects of genetic counselling in these
couples are discussed. In conclusion, we recommend genetic counselling and
chromosomal analysis of men and women prior to ICSI therapy.
