Abstract/OtherAbstract:
The frequency of numerical and structural chromosomal abnormalities was studied in the sperm of a lymphoma patient 3 years after MACOP-B chemotherapy (CT). Sperm karyotyping was performed by fusion of human sperm with hamster oocytes and analysis of 193 Q-banded sperm chromosomes. Multicolor fluorescence in situ hybridization (FISH) was performed on 10,228 sperm for analysis of disomy frequencies for chromosomes 1 and 12 and on 10,664 sperm for chromosomes X and Y. Sperm karyotyping demonstrated numerical abnormalities in 7.3% of the spreads, 6.7% hypohaploid and 0.5% hyperhaploid, giving a conservative estimate of aneuploidy of 1%. Structural chromosomal abnormalities were present in 7.3% of the karyotypes and 0.5% had both numerical and structural abnormalities. Results of FISH analyses yielded disomy frequencies of 0.10%, 0.11%, 0.04%, 0.05%, and 0.18% for chromosomes 1, 12, X, Y, and XY, respectively. The frequency of diploid sperm was 0.09%. The frequency of abnormalities was not significantly increased compared to control donors for any of the studies. Also, the frequencies of X- and Y-bearing sperm did not differ significantly from 50% in the sperm karyotyping or FISH studies.
