Abstract: Sperm chromosome of subject s with hepatitis B virus infection were prepared using interspecific in vit ro fertilization with zona2f ree hamster eggs. Fluorescence in situ hybridization ( FISH) to sperm chromosome spreads was carried out with biotin2labelled full length HBV DNA. There was significant difference in the frequencies of sperms with chromosome aberrations between subject s with HBV infection and cont rol. FISH showed that HBV DNA integrated into sperm chromosomes , and that multisite and nonspecific integrations were the features of HBV in sperm chromosomes. These result s indicate that HBV infection affect s on the sperm chromosome broadly.

Key words: hepatitis B virus, human sperm chromosome, zona2f ree hamster egg, FISH, chromosome aberration, DNA integration, vertical t ransmission
