Human papilloma virus infection and miscarriage: is there an association?

Abstract

Human papilloma virus (HPV) infection is the most common viral infection of the reproductive tract. HPV infection is more prevalent in pregnant than in age-matched non-pregnant women and its prevalence increases as pregnancy progresses. A number of reports evaluated the role of HPV infection in miscarriages. In the present review, we summarize the existing evidence regarding the association between HPV infection and miscarriage. It is still unclear whether HPV infection is associated with increased risk for miscarriage. Studies in the field yielded conflicting findings and their conclusions are limited by a small sample size and/or methodological limitations. On the other hand, preclinical data support a role of HPV infection in placental dysfunction. Given the high prevalence of HPV infection and the possibility that vaccination against HPV might protect against miscarriage, more studies are needed to elucidate whether this common infection is associated with increased risk for miscarriage.
