Purpose: This study aimed to investigate male HPV infection, re-examination rate, clearance rate and relevant influencing factors as well as HPV infection between heterosexual partners in Wenzhou, China.
Methods: The study enrolled 2359 men who accepted ≥ 1 HPV detection in the First Affiliated Hospital of Wenzhou Medical University between June 2014 and June 2020. An outpatient follow-up was carried out for collecting HPV re-test results among males who were tested HPV positive. In addition, we collected female sexual partners’ HPV infection state through outpatient information system or telephone call. For males who had not re-tested HPV more than half a year after the first HPV positive result, a telephone follow-up would be provided.
Results: Male HPV prevalence was 39.39% (928/2359) at baseline, of which the median age was 38.00 years. The percentage of co-infection and HR HPV infection was 35.24% (327/928) and 61.08% (874/1431). Genotype-specific concordance of HPV infection among heterosexual partners was 61.19% (123/201). The most common types were HPV6, HPV52, HPV16, HPV53, HPV11, HPV43 and HPV58. Percentage of males finishing HPV re-examination was low (40.09%). Infection with HR HPV, discomfort or HPV-related diseases and sexual partners with HPV infection were possible motivator for male HPV re-test. The medium time to male HPV clearance was 300.000 (95% CI=274.845– 325.155) days. Infection with HR HPV, sexual partners with HPV infection and growth of age might prolong HPV persistence time included.
Conclusion: Males are susceptible population for genital HPV infection as well as females. Whereas, males are generally less aware of HPV and its influence on their couples. The study showed that male HPV testing as well as the role of males in the diagnosis and treatment of HPV-associated cervical diseases for females should be popularized and co-treatment of couples was necessary.
