Abstract
The objective of this study was to determine the aneuploidy level in spermatozoa in two men with globozoospermia. Sperm nuclei were analysed by fluorescence in-situ hybridization (FISH) in two infertile males with globozoospermia. Dual FISH for chromosomes 7 and 9, 13 and 21, and triple FISH for chromosomes X, Y, and 18 was performed. The main outcome measured was meiotic segregation differences between both globozoospermic men and controls. A statistically significant difference in disomies 13 and 21 was found between patients 1 and 2. The diploidy rate of spermatozoa of patient 1 (0.876%) was significantly increased compared with that of patient 2 (0.304%) and control men (0.293%). In conclusion there seems to be a slightly increased frequency of aneuploidy in round-headed spermatozoa. However, it is unlikely that these aneuploid spermatozoa would be used in assisted reproduction techniques.Keywords
