Men, who consumed on an average over 9.9 grams of alcohol per day, had a significantly higher risk of HPV infection, the findings showed.

Men, who drank more alcohol, had an increased risk of HPV infection, independent of the number of sexual partners they had.

This suggests that increased consumption of alcohol may impair men's immune responses to HPV, the study noted.

"Our findings provide additional support to current public health messaging regarding the importance of moderate alcohol consumption and smoking cessation," said researcher Matthew Schabath from the Moffitt Cancer Center in US.

HPV causes genital warts in both men and women and is a contributing factor to a number of different cancers in women.

More recent studies have shown that HPV can also cause penile, anal and oropharyngeal cancer in men.

For the new study, the researchers analyzed potential risk factors for HPV infection in over 1,300 men in the US.

DNA analysis was used to confirm the presence of HPV and the participants answered detailed surveys about alcohol consumption, smoking and sexual activity.
