The chromosome complement of human spermatozoa has been analyzed after their intracytoplasmic injection into unfertilized mouse oocytes. A total of 427 metaphase plates have been obtained, including 176 metaphase plates from spermatozoa with normal head morphology (108 and 68 spermatozoa from patients with normal (the control group) and abnormal spermogram parameters, respectively), and 251 metaphase plates from spermatozoa with abnormal heads (76, 91, 67, and 17 spermatozoa with large, amorphous, elongated, and round heads, respectively). The frequency of chromosome abnormalities in the control group is 26.1%, with hyperploidy, hypoploidy, and structural aberrations accounting for 7.4, 12.3, and 6.4% of the abnormalities, respectively. In none of the groups did the ratio between the numbers of X- and Y-bearing spermatozoa significantly differ from 1 : 1. The diploidy frequency was significantly higher in spermatozoa with large and amorphous heads compared to the control group (2.36, 3.29, and 0%, respectively). None of the groups of spermatozoa differed from the control group with respect to the frequency of structural aberrations. The type of the abnormal head morphology has been found to be correlated with the sperm chromosome complement.
