Chromosomal analysis of 240 spermatozoa from 18 normal men was performed using in vitro fertilization of zona-free golden hamster eggs. The frequency of chromosome abnormalities in this population was 9.2% (22/240). Of the abnormal complements, 18 were aneuploid (13 hyperploid and five hypoploid) and four had a chromosome break. The sex ratio of Y-bearing to X-bearing sperm was .68. The frequency and type of sperm chromosome abnormalities is compared with those seen in spontaneous abortions.
