[DNA of the hepatitis B virus in human generative cells]

In spermatozoa of certain patients nucleotide sequences of hepatitis B virus were revealed in an integrated (chromosomal) and free states by means of dot- and blot-hybridization with a cloned HBV-probe. These observations support the conclusion made earlier on the lack of strict hepatotropism for HBV and, in addition, point to a possible involvement of HBV genomes in some molecular pathologies of men.
