Impact of human papillomavirus (HPV) prophylactic vaccination on infertile male patients with HPV semen infection: A systematic review
Abstract
Purpose: To characterize the impact of prophylactic vaccination against human papillomavirus (HPV) on infertile male patients with HPV semen infection.
Methods: This systematic review followed the Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines. First, an electronic search of PubMed, Scopus and Web of Science databases from 2018 to 2023 using specific keywords was conducted. Thereafter, three authors independently screened the articles and removed duplicates. Following the acquisition of the papers, a quality analysis was conducted using the Strengthening the Reporting of Observational Studies in Epidemiology Criteria.
Results: A total of 41 pregnancies were reported out of which 15.3 % were in control group and 38.9 % were in the vaccinated group (p < 0.05). The clearance of HPV DNA correlated significantly with a serum HPV antibody titer of ≥ 1:125 at initial examination. Compared with individuals who tested negative for HPV, those who became seropositive at 12 (p = 0.039), 18 (p = 0.034) and 24 months (p = 0.034) had fewer multiple infections and a lower incidence of HPV infection in semen.
Conclusion: Examination of the association between male fertility and HPV reveals a clear correlation between HPV infection and male infertility, specifically asthenospermia and oligoasthenospermia. Further studies are needed to fully understand the benefits of this approach in managing male infertility.
