Molecular detection of HHV-1, HHV-2, HHV-5 and HBV in semen of fertile and infertile men by multiplex PCR method

Background and Objectives: A great diversity of factors including viruses such as human herpes virus 1 2 (HHV-1 2), human herpes virus 5 (HHV-5), and hepatitis B virus (HBV) play key roles in sterility and it is worth noting that male infertil- ity accounts for nearly 50% of barrenness, globally. In this regard, we evaluated the prevalence of the aforementioned viruses in semen specimens of two distinct groups of men referred to Novin Infertility Center in Mashhad, Iran. Materials and Methods: In this cross-sectional study, 300 semen samples were collected from 150 infertile and 150 fertile men. Subsequently, genomic DNA was extracted before performing multiplex polymerase chain reaction (PCR). Eventually, the results were analyzed via SPSS Statistics V.16.0. Results: Out of 300 specimens, 183 (61.1%) were positive at least for one of the forenamed viruses; genome detection of HHV-1 2, HHV-5, and HBV were 27%, 18%, 36.66%, and 4%, respectively. Conclusion: The current study found no correlation between infertility and HBV, HHV-5, and HHV-1 2, which may have to do with factors like sample size, the geographical distribution of the viruses, and the lifestyle (sexual behavior) of the participants. These results emphasize the implementation of such studies on a broader scale to determine the exact factors involved in infertility.
