Preliminary investigation shows HPV infection may reduce sperm concentration in Korean men, suggesting implications for male infertility.
The observed HPV prevalence was higher than previously reported in Korean studies. This preliminary investigation suggests a potential association between HPV infection and reductions in sperm concentration and total sperm numbers, although causality cannot be inferred. Given the small sample size, especially the limited number of HPV-positive cases, larger studies are required to clarify the precise role of HPV infection in male infertility.
