Viral infection of spermatozoa. Part 1. Hepatitis B virus and human papillomavirus (review)

Abstract

Intragametal viral infection of spermatozoa can cause true vertical transmission of viruses through germ cells. Currently, human papilloma-virus, including oncogenic risk strains, and hepatitis B virus, have been detected in spermatozoa. The possibility of vertical transmission of hepatitis B virus and human papillomavirus has been proven.Intragametal infection of spermatozoa with viruses of human papillomavirus and hepatitis B virus leads to abnormalities in the development of the embryo and can cause spontaneous abortions both duringnatural conception and when using assisted reproductive technologies.The development of adequate methods for diagnosing an intragametal spermatozoa virus infection will make it possible to find out, at least in some patients, the cause of infertility and pregnancy abnormalities and apply appropriate antiviral therapy in preparation for natural conception or the use of assisted reproductive technologies.
