ABSTRACT

Objective. To assess the prevalence of Human Papillomavirus (HPV) Deoxyribonucleic acid (DNA), and of clinical and subclinical condilomatosis in men whose sex partners had been diagnosed with cervical intraepithelial neoplasia. Material and Methods. A cross-sectional study was conducted from October 1997 to August 1998, among 200 men aged 17 to 64 years referred to the Oncology Department of the National Institute of Perinatology in Mexico City. A physical examination of the penis (penoscopy) was performed after applying 3-5% acetic acid. A colposcope was used to identify acetowhite areas and vascular abnormalities associated with HPV infection. HPV DNA was detected by PCR and reverse line hybridization. The exploratory and univariant statistical analysis was made with the package Stata V6.0. Results. The β-globin gene was present in 93.5% (n=187) of the 200 urethral exfoliated cell samples collected. HPV DNA was detected in only 2% (4/187) of the study subjects. Penoscopy data showed the presence of acetowhite areas in 43% (81/187) of subjects. Conclusions. Study findings show that the presence of HPV DNA in urethra is uncommon, as has been reported in several previous studies. Research is needed to evaluate the presence of HPV DNA in the coronal sulcus, as compared with the distal urethral region.
