Abstract
Some men have elevated levels of sperm chromosome aneuploidy. In this study, we have evaluated and summarized sperm aneuploidy rates in male infertility patients and control groups. The mean aneuploidy rate for five chromosomes (X, Y, 13, 18, 21) was 1.2 +/- 0.1 for fertile controls, 1.4 +/- 0.1 for a general population control group, and 5.8 +/- 1.14 for the patients. When the patients were classified by the type of male factor infertility, the total aneuploidy rate was 2.6 +/- 0.3 in men with moderately diminished semen quality (n = 7), 4.0 +/- 0.3 patients with severe teratoasthenooligozoospermia, and 15.9 +/- 3.8 for men with rare ultrastructure defects such as round head only syndrome or severe tail agenesis. Some infertility patients have a severely elevated level of sperm chromosome aneuploidy, which may contribute to infertility or diminish the likelihood of a successful outcome from IVF/ICSI. The severity of sperm chromosome aneuploidy appears to be proportional to the severity of abnormal semen quality: in particular, abnormal morphology. The high rates of aneuploidy in patients with severe ultrastructure defects suggest that caution should be employed in counseling those patients prior to IVF/ICSI.Keywords
