Data was collected on self-reported clinically diagnosed genital warts, and various lifestyle habits. Results Ever having had clinically diagnosed genital warts was reported by 7.9\% of the men. The median age at first occurrence was 22 years. Genital warts within the previous 12 months were reported by 0.92\% of the men, with a peak of 1.83\% among men aged 21{\textendash}24 years. The likelihood of reporting genital warts was strongly correlated with the lifetime number of sex partners (OR 8.0; 95\% CI 6.0 to 10.8 for >=15 partners vs 1{\textendash}2 partners). Other factors associated with an increased risk for genital warts included ever having smoked and having had other sexually transmitted infections. Conclusions Almost 8\% of Danish men aged 18{\textendash}45 years reported having had a diagnosis of genital warts. The results provide baseline information for developing and monitoring prevention strategies against genital warts, such as vaccination against human papillomavirus types 6 and 11.}, issn = {1368-4973}, URL = {https://sti.bmj.com/content/88/8/640}, eprint = {https://sti.bmj.com/content/88/8/640.full.pdf}, journal = {Sexually Transmitted Infections} }
