Abstract: Purpose : To detect the f requencies of aneuploidy for chromosome 9 and 18 in sperm of healthy males. Methods : Two-color fluorescence in situ hybridization ( FISH) was performed on sperm nuclei using cent romeric probes for chromosome 9 and 18 , and the f requencies of aneuploidy were scored. Results : 156 955 sperm nuclei were detected in 16 healthy adults. About 10 000 sperm nuclei were scored from each of 16 donors and the average efficiency of hybridization was above 99 %. The mean f requencies of disomy obtained were 0. 050 % ±0. 030 % for chromosome 9 ,0. 033 %±0. 025 %for chromosome 18. The nullisomy frequencies of chromosome 9 and 18 were found to be 0. 067 %±0. 037 % , 0. 048 %±0. 034 % respectively. Diploidy was observed as 0. 040 %±0. 036 %. The f requency of total numerical aberration was 0. 218 %±0. 071 %. Con-clusion : The aneuploidy for chromosome 9 and 18 in sperm of 16 healthy males was detected in this research , the result was similar to that of traditional sperm karyotype analysis.
