| Summary: | Abstract The true HPV prevalence in the foreskins of infants and children has been little documented, but reporting on this prevalence is of great importance given its impact on the rationale for treating asymptomatic boys. We searched multiple databases from 1960 to 2016 for observational or prospective studies that reported on HPV prevalence in foreskins. We conducted a meta-analysis using a random-effects model to pool for HPV prevalence in the foreskins of infants and children. Eight studies, with a total of 556 infants and children with phimosis, were eligible for the meta-analysis. The pooled overall prevalence of general HPV, high-risk HPV, low-risk HPV, HPV 16/18, HPV 16, and HPV 18 were 17.3 (95%CI: 0.8–46.3), 12.1 (95% CI: 0.9–31.5), 2.4 (95% CI: 0.0–11.2), 4.8 (95% CI: 0.0–16.8), 1.7 (95% CI: 0.0–5.1), and 0 (95% CI: 0–0.5), respectively. The estimated HPV prevalence in foreskins was not zero among infants and children, which implies HPV transmission other than by sexual contact. Considering that high-risk HPV is detected in asymptomatic infants and children, future studies are warranted to determine whether preventive treatments in asymptomatic infants and children could be effective in preventing persistence or transmission of high-risk HPV.
