Anogenital warts (AGW) remains one of the most common sexually transmitted infections STIs) among male patients visiting STIs clinics. AGW is caused by human papillomavirus, in particularly types 6 and 11. The objectives of this study were to (1) estimate the prevalence of AGW among male patients attending the STIs clinic, Department of Disease Control, (2) describe the sexual risk behaviors, and (3) describe the clinical manifestations among male patients diagnosed with AGW. We conducted a retrospective descriptive study using 9,160 medical records from male patients visiting the clinic between October 2010 and September 2015. Descriptive statistics, 95% confidence interval, and chi-square test were employed for data analysis. The findings indicated that the prevalence of AGW among male patients attending the clinic was 11.6% (95%CI = 10.9-12.2). The prevalence of AGW among men who have sex with women (MSW) was 8.0% (95% CI = 7.4-8.7) and among men who have sex with men (MSM) was 21.4% (95% CI = 19.8-23.1). The prevalence among MSW aged 40 years and older was 28.1% (95% CI = 24.4-32.1) and the prevalence among MSM aged 20-24 years was 26.6% (95% CI = 22.9-30.7). Among those male patients diagnosed with AGW, consistent condom use during sexual intercourse in the past 3 months were only 13.6%. Anatomical distribution of AGW found that prepuce was the most common location for AGW in MSW, and rectum was the most common in MSM. Eventually, effective interventions to reduce AGW transmission purposively for male patients attending the STIs clinic are needed, especially young MSM.
