Аннотация:There are quite a number of viruses known that can infect the semen: human immunodeficiency virus, human papillomavirus, hepatitis B and hepatitis C viruses, herpes simplex virus (HSV), Epstein–Barr virus (EBV), and cytomegalovirus (CMV). For some of these viruses, intracellular localization in spermatozoa has been proven or discussed earlier. In our previous studies, we have detected intracellularly localized capsids of the Herpesviridae family viruses. But the role of vertical virus transmission for vertical dissemination of infection as well as for further abnormalities of embryo development is not clear up to now.
