Presence of human papillomavirus in semen in relation to semen quality

Is the presence of human papillomavirus (HPV) in semen associated with impairment of semen quality? In a large cohort of males seeking fertility evaluation, no associations were observed between seminal HPV presence and semen parameters. HPV is commonly detected in semen samples. Whether the presence of HPV is related to impairment of semen quality, remains unclear. This cross-sectional study included a cohort of 430 males. Male partners in couples seeking fertility evaluation provided one semen sample per person. Semen samples were tested for HPV-DNA using GP5+/6+-PCR. Sperm concentration was counted and motility was assessed in a Makler counting chamber at a magnification of x200. The presence of antisperm antibodies was assessed by a mixed agglutination reaction (MAR)-test. Overall HPV was detected in 14.9% (64/430) of semen samples, including 2.1% (9/430) that contained both high-risk (hr) HPV and low-risk (lr) HPV types, 8.8% (38/430) with exclusively hrHPV types and 4.0% (17/430) with exclusively lrHPV types. The presence of HPV in semen was not associated with the age of the participants, seminal pH, semen volume, total sperm count, sperm concentration, progressive motility or the presence of antisperm antibodies. This study did not observe an association between HPV presence in semen and impairment of semen quality. However, we cannot exclude an effect of seminal HPV on early embryo development and clinical reproductive outcomes. As HPV is frequently present in semen, screening of donor semen for HPV should be considered to prevent iatrogenic cervical HPV infections in the recipient. However our findings do not support standardized HPV testing of semen in the diagnostic work-up of subfertile couples.
