Despite their similar semen parameters, infertile men with normal karyotypes displayed more frequent increases in sperm aneuploidy, particularly involving the sex chromosomes, than infertile men who were carriers of chromosomal rearrangements. The difference in the magnitude and type of sperm aneuploidy between the two infertile groups is likely related to the different causes of infertility.
