HPV (Human Papilloma Virus)
There is increasing evidence that the HPV virus (responsible for genital warts and cervical cancer in women) is thought to be responsible for a recent increase in head and neck cancer among men and women. This is due to the fact that HPV can also be spread through oral sex, and recent research has strongly encouraged the use of condoms or rubber dams when performing oral sex in order to minimize risk of contraction of HPV.
It is possible to contract HPV during sexual intercourse even with the use of a condom, and there is currently no HPV test currently available for men.
There is a vaccine available for both sexes that protects against HPV strain 16, which in one NEJM study accounted for over 95% of the HPV-associated head and neck cancers. There is currently no direct evidence that the HPV vaccine will prevent HPV head and neck cancers, and using barrier methods is still advised.

FDA Approves New Indication for Gardasil to Prevent Genital Warts in Men and Boys
The U.S. Food and Drug Administration today approved use of the vaccine Gardasil for the prevention of genital warts (condyloma acuminata) due to human papillomavirus (HPV) types 6 and 11 in boys and men, ages 9 through 26.
Each year, about 2 out of every 1,000 men in the United States are newly diagnosed with genital warts.
Gardasil currently is approved for use in girls and women ages 9 through 26 for the prevention of cervical, vulvar and vaginal cancer caused by HPV types 16 and 18; precancerous lesions caused by types 6, 11, 16, and 18; and genital warts caused by types 6 and 11.
HPV is the most common sexually transmitted infection in the United States and most genital warts are caused by HPV infection.
“This vaccine is the first preventive therapy against genital warts in boys and men ages 9 through 26, and, as a result, fewer men will need to undergo treatment for genital warts,” said Karen Midthun, M.D., acting director of the FDA’s Center for Biologics Evaluation and Research.
Gardasil’s effectiveness was studied in a randomized trial of 4,055 males ages 16 through 26 years old. The results showed that in men who were not infected by HPV types 6 and 11 at the start of the study, Gardasil was nearly 90 percent effective in preventing genital warts caused by infection with HPV types 6 and 11.
Studies were conducted to measure the immune response to the vaccine in boys ages 9 through 15. The results showed that the immune response was as good as that found in the 16 through 26 years age group, indicating that the vaccine should have similar effectiveness.
The manufacturer will conduct postmarketing studies to obtain additional information on the safety and effectiveness of Gardasil in boys and men.
Gardasil is given as three injections over a 6-month period. Headache, fever and pain at the injection site, itching, redness, swelling and bruising, were the most common side effects observed.
Gardasil is manufactured by Merck and Company Inc. of Whitehouse Station, N.J.
