We interviewed 779 men who requested a vasectomy in 27 public clinics in 14 states of Mexico. Exfoliated cells were obtained from the scrotum, the shaft of the penis, the top of the penis including the coronal sulcus, the glans and the opening of the meatus. HPV testing was performed using biotinylated L1 consensus primers and reverse line blot. Unconditional logistic regression was used to estimate odds ratios (ORs) of being HPV\u2010positive and corresponding 95% confidence intervals (CIs). The prevalence of any type of HPV was 8.7%. HPV positivity was highest among men below age 25 (13.6%), and lowest among men aged 40 years or older (6.0%). The most commonly found HPV types were, in decreasing order, HPV59, 51, 6, 16 and 58. Lifetime number of sexual partners was associated with HPV positivity (OR for \u22654 <jats:italic>vs.<\/jats:italic> 1 partner = 3.7, 95% CI: 2.0\u20136.8), mainly on account of the strong association with number of occasional and sex\u2010worker partners. Condom use with both regular (OR = 0.4, 95% CI: 0.1\u20131.0) and sex\u2010worker (OR = 0.1, 95% CI: 0.0\u20130.3) partners and circumcision (OR = 0.2, 95% CI: 0.1\u20130.4) were inversely associated with HPV positivity. HPV prevalence in Mexican men was similar to the prevalence found in Mexican women of the same age groups. The association between HPV positivity and lifetime number of sexual partners in the present low\u2010risk male population is one of the strongest ever reported in studies in men. Condom use and circumcision were associated with a strong reduction in HPV prevalence. \u00a9 2006 Wiley\u2010Liss,
