Human papillomavirus infection (HPV) and pregnancy

Human papillomavirus (HPV) is the most common sexually transmitted viral infection worldwide, which may result in the development in benign lesions or malignant tumors. The prevalence of HPV infection is twice as high in pregnancy as in non-pregnant women. Additionally, there is a risk of vertical transmission of HPV from mother to fetus during pregnancy or childbirth. Various studies have reported an increased risk of adverse pregnancy outcomes in HPV-positive women, including miscarriage, preterm birth, premature rupture of membranes, preeclampsia, fetal growth restriction, and fetal death. HPV vaccination is not currently recommended during pregnancy. On the other hand, there is no evidence linking HPV vaccination during pregnancy with adverse pregnancy outcomes and termination of pregnancy is not justified in this case.
