世界五成男性均感染有致癌病毒HPV16
Around 50 percent of the men have human papillomavirus (HPV) which often goes undetected and is easily passed on during unprotected sex.
約50%的男性都感染有乳頭瘤病毒(HPV)，該病毒往往被男性忽視，性行爲時若未採取保護措施很容易傳染給他人。
Of the group, around six percent of men yearly contract a new HPV 16 infection, the virus Most well known for causing cervical cancer in women and also causing cancers in men.
其中感染了該病毒的約6%的男性每年會感染HPV16這種變異病毒品種。HPV16會引發女性子宮癌，也會在男性身上造成一系列癌症病變。
While the majority of the nearly 200 known types of HPV cause no symptoms in most people, some cause warts while others lead to cancers of the genitals and throat.
HPV有約莫200種變體，其中大部分都不會對大衆產生危害，然而其中一些會造成病毒疣，有的甚至引發陰莖癌和咽喉癌。
The study further reinforces calls for a male HPV vaccination program to be rolled out worldwide to nip the infection in the bud.
這項研究進一步呼籲在全世界範圍內對男性注射HPV疫苗的衛生項目，防止感染擴大嚴重化。
Professor Anna Giuliano of the H Lee Moffitt Cancer Center and Research Institute in Tampa, Florida, found 32,000 cases of cancers in men and women in the USA in 2009 were attributable to HPV infection.
位於佛羅里達坦帕的H•李•墨菲特癌症中心和研究機構成員安娜•朱利亞諾發現2009年全美約有三萬二千多癌症病例是由HPV感染導致的。
It also found anogenital warts were the most common result of HPV, with 205 cases per 100,000 diagnosed every year in the USA.
該研究還發現肛門-生殖器疣也主要是由HPV造成的，在美國一萬例確診中就有205例是因感染了該病毒。
In addition to the diseases HPV causes directly in men, the virus is readily transmitted from men to women putting them at greater risk.
HPV除了能直接造成男性疾病外，還能通過性行爲傳播給女性，使其致病機率加大。
The study found men who had more than one lover were more prone to catching the virus.
該研究還發現性伴侶超過一人的感染該病毒的機率更大。
The chances of cancer-causing (oncogenic) HPV infection was 2.4 times higher from men who had had 50 or more female partners compared with no partners or just one partner and 2.6 times higher for men who had at least three male anal sex partners compared with no recent partners.
女伴累計超過50人的男性感染致癌HPV的機率是沒有女伴或只有一名女伴的2.4倍，而至少擁有三名男性性伴侶的男性比沒有男伴的男性高2.6倍。
The average duration of HPV infection was seven and a half months for any HPV and 12 months for the cancer-causing HPV type 16.
一般HPV感染平均持續時間爲7.5個月，而致癌的HPV16則長達12個月。
HPV also causes 80 percent of cervical cancer cases. The findings are published online in the Journal Lancet.
80%的子宮癌是由HPV引發的。這些研究結果發表在醫學期刊《柳葉刀》上。
