The role of the male reproductive tract as a reservoir for human papillomavirus (HPV) infection is poorly understood. To analyze the presence of HPV DNA, 27 samples, comprising postvasectomy semen samples and pre-and postejaculation urine samples, were obtained from 18 men recalled for follow-up. HPV DNA was analyzed by nested polymerase chain reaction, confirmed with Southern blot hybridization, cloned, and sequenced. Multiple HPV types were found in different DNA samples of the same men. Five (18.5%) of 27 vas deferens samples contained HPV type 6, 11, or 16. Five (27.8%) of 18 seminal plasma samples (secretions without semen cells) were HPV DNA positive. None of the men had both vas deferens and semen plasma samples HPV positive. Several HPV types can be detected in the male reproductive tract at the same time. This is the first report to show HPV DNA in the vas deferens.
