According to an article published in The Lancet in electronic pre-print , approximately 50 percent of men in a general population sample was infected with the Human Papilloma Virus (HPV).
addition, each year 6 percent of them acquire a new HPV 16 infection, the virus better known to cause cancer in both women (cervix) and men, reported the National Institute of Public Health (INSP).
The study, conducted by three research groups, including one of the INSP, having multiple partners, whether male or female, makes men more prone to infection caused by HPV.
HPV is easily transmitted from men to women, raising the risk of disease in women, so the authors, the Cancer Center and Research Institute in Tampa, Florida and the Ludwig Institute, Sao Paulo, Brazil, indicate that understanding the nature of the virus in men is vital to public health, in addition to this knowledge is used to develop cost-effective models of HPV vaccination in men.
The study looked at 159 thousand men between 18 and 70 years of age (mean 32 years), HIV negative and no history of cancer, native to the United States, Brazil and Mexico, who were assessed every six months for an average time over two years.
The probability of developing an HPV type associated with cancer was 2.4 times higher in men who had fifty or more female partners than in those with one partner or had no, and 2.6 times higher in men who had at least three male partners with whom anal sex, that couples who had no recent.
The average duration of HPV infection was 7.5 months for any HPV, and 12 months for oncogenic HPV type 16.
These data reveal the enormous frequency of HPV in men that in the near future, making it feasible to consider that the infection by this virus in anogenital region is part of the everyday sexual life, so it is necessary to establish preventive measures primary (HPV vaccines) and secondary (HPV and Pap tests newspapers), to improve strategies for prevention and control of anogenital cancer, the researchers concluded.
