The purpose of this study was to analyze the rate of numerical chromosomal anomalies in sperm nuclei. Nine infertile patients and 25 control donors were evaluated for chromsomes 16, 18, X and Y. The infertile patients had normal karyotype but abnormal semen parameters. The mean rate of disomies was significantly higher in infertile males. In conclusion, patients with teratozoospermia or oligo-astheno-teratozoospermia may have an increased rate of sperm aneuploidy therefore a higher risk of producing genetically abnormal embryos. These findings suggest the necessity of genetic counselling before assisted reproductive techniques. Those patients who have high rate of chromosomal anomalies in sperms preimplantation or prenatal diagnosis should be considered. Future studies are needed to examine the aneuploidy rate for many of the remaining chromosomes and to decide the relationship between clinical phenotype and aneuploid frequency in sperm nuclei.
