Sperm DNA integrity and human papillomavirus (HPV) infections: a controversy that could be resolved by a new molecular approach

Study question: The aim was to determine if HPVs affect spermatozoa DNA integrity. To resolve the discrepancy regarding the association between HPV infections and sperm DNA damage. Summary answer: To elucidate if HPV impairs DNA integrity, we suggest to investigate HPV DNA positivity in spermatozoa by a differential lysis procedure before TUNEL assay.
