Men infected with high-risk types of HPV could struggle with fertility
Researchers from Argentina compared semen quality between men infected with high-risk (HR-HPV) and low-risk (LR-HPV) genotypes of human papillomavirus and HPV negative men. They showed that HR-HPV positive men had higher percentages of dead sperm, a higher level of reactive oxygen species, and a lower count of white blood cells in their semen. These results suggest that HR-HPV positive men, but not LR-HPV positive men, may have lower fertility due to oxidative damage to sperm.
