Global and regional estimates of genital human papillomavirus prevalence among men: a systematic review and meta-analysis. Lancet Glob Health 2023; 11:e1345-e1362. [PMID: 37591583 PMCID: PMC10447222 DOI: 10.1016/s2214-109x(23)00305-4] [Citation(s) in RCA: 10] [Impact Index Per Article: 10.0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/23/2022] [Revised: 05/26/2023] [Accepted: 06/20/2023] [Indexed: 08/19/2023]
Abstract
BACKGROUND The epidemiology of human papillomavirus (HPV) in women has been well documented. Less is known about the epidemiology of HPV in men. We aim to provide updated global and regional pooled overall, type-specific, and age-specific prevalence estimates of genital HPV infection in men. METHODS We conducted a systematic review and meta-analysis to assess the prevalence of genital HPV infection in the general male population. We searched Embase, Ovid MEDLINE, and the Global Index Medicus for studies published between Jan 1, 1995, and June 1, 2022. Inclusion criteria were population-based surveys in men aged 15 years or older or HPV prevalence studies with a sample size of at least 50 men with no HPV-related pathology or known risk factors for HPV infection that collected samples from anogenital sites and used PCR or hybrid capture 2 techniques for HPV DNA detection. Exclusion criteria were studies conducted among populations at increased risk of HPV infection, exclusively conducted among circumcised men, and based on urine or semen samples. We screened identified reports and extracted summary-level data from those that were eligible. Data were extracted by two researchers independently and reviewed by a third, and discrepancies were resolved by consensus. We extracted only data on mucosal α-genus HPVs. Global and regional age-specific prevalences for any HPV, high-risk (HR)-HPV, and individual HPV types were estimated using random-effects models for meta-analysis and grouped by UN Sustainable Development Goals geographical classification. FINDINGS We identified 5685 publications from database searches, of which 65 studies (comprising 44 769 men) were included from 35 countries. The global pooled prevalence was 31% (95% CI 27-35) for any HPV and 21% (18-24) for HR-HPV. HPV-16 was the most prevalent HPV genotype (5%, 95% CI 4-7) followed by HPV-6 (4%, 3-5). HPV prevalence was high in young adults, reaching a maximum between the ages of 25 years and 29 years, and stabilised or slightly decreased thereafter. Pooled prevalence estimates were similar for the UN Sustainable Development Goal geographical regions of Europe and Northern America, Sub-Saharan Africa, Latin America and the Caribbean, and Australia and New Zealand (Oceania). The estimates for Eastern and South-Eastern Asia were half that of the other regions. INTERPRETATION Almost one in three men worldwide are infected with at least one genital HPV type and around one in five men are infected with one or more HR-HPV types. Our findings show that HPV prevalence is high in men over the age of 15 years and support that sexually active men, regardless of age, are an important reservoir of HPV genital infection. These estimates emphasise the importance of incorporating men in comprehensive HPV prevention strategies to reduce HPV-related morbidity and mortality in men and ultimately achieve elimination of cervical cancer and other HPV-related diseases.

Clin Microbiol Infect 2023:S1198-743X(23)00149-0. [PMID: 37011808 DOI: 10.1016/j.cmi.2023.03.028] [Citation(s) in RCA: 4] [Impact Index Per Article: 4.0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/28/2022] [Revised: 03/05/2023] [Accepted: 03/25/2023] [Indexed: 04/03/2023]
Abstract
BACKGROUND Previous studies have suggested a protective effect of male circumcision on human papillomavirus (HPV) infections in males, and that this protection may be conferred to their female sexual partners. OBJECTIVES To synthesize the available evidence on the association between male circumcision and HPV infections in males and females. DATA SOURCES We searched MEDLINE, Embase, Scopus, Cochrane, LILACS, and ProQuest Dissertations & Theses Global for records published up to 22 June 2022. STUDY ELIGIBILITY We considered observational and experimental studies that assessed male circumcision status and HPV prevalence, incidence, or clearance in males or females for inclusion. PARTICIPANTS Males and their female sexual partners who were tested for genital HPV infection. INTERVENTIONS Male circumcision compared to no circumcision. RISK OF BIAS ASSESSMENT The Newcastle-Ottawa scale was used for observational studies and the Cochrane risk-of-bias tool was used for randomized trials. DATA SYNTHESIS We estimated summary measures of effect and 95% confidence intervals (CI) for the prevalence, incidence, and clearance of HPV infections in males and females using random-effects meta-analysis. We assessed effect modification of circumcision on HPV prevalence by penile site in males using random-effects meta-regression. RESULTS Across 32 studies, male circumcision was associated with decreased odds of prevalent HPV infections (OR 0.45, CI 0.34-0.61), a reduced incidence rate of HPV infections (IRR 0.69, CI 0.57-0.83), and an increased risk of clearing HPV infections (RR 1.44, CI 1.28-1.61) at the glans penis among male subjects. Circumcision conferred greater protection against infection at the glans than shaft (OR 0.68, 95% CI 0.48-0.98). Females with circumcised partners were protected from all outcomes. CONCLUSIONS Male circumcision may protect against various HPV infection outcomes, suggesting its prophylactic potential. Understanding site-specific effects of circumcision on HPV infection prevalence has important implications for studies of HPV transmission.

Association of smoking with anal high-risk HPV infection and histologically confirmed anal high-grade squamous intraepithelial lesions among a clinic-based population in Puerto Rico. Cancer Treat Res Commun 2021; 30:100503. [PMID: 34999478 PMCID: PMC9253704 DOI: 10.1016/j.ctarc.2021.100503] [Citation(s) in RCA: 4] [Impact Index Per Article: 1.3] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/09/2021] [Revised: 12/23/2021] [Accepted: 12/24/2021] [Indexed: 10/19/2022]
Abstract
INTRODUCTION Current smoking is a risk factor for anal cancer. Yet, its association with anal human papillomavirus infection (HPV) and anal high-grade squamous intraepithelial lesions (HSIL) remains unclear. We assessed the association of smoking with 1) anal high-risk HPV (HR-HPV) infection and 2) anal HSIL. METHODS Data from the baseline visit of patients from the Anal Neoplasia Clinic of the University of Puerto Rico Comprehensive Cancer Center (May 2015- June 2021) was analyzed. Patients were eligible if they had information on smoking status, complete high-resolution anoscopy (HRA) with biopsy, and HR-HPV testing (n = 427). Logistic regression models estimated the odds ratio (OR) with 95% confidence intervals (CIs) adjusting for covariates. RESULTS Mean age was 44 ± 13 years, 69% were men, 74% were HIV-infected, and 25% reported being current smokers. 74% had anal HR-HPV infection. HSIL was diagnosed in 40% of patients. Current smokers had significantly higher odds (OR: 1.71, 95% CI: 1.04-2.82) of having HSIL compared to non-smokers after adjusting for age, sexual risk group, lifetime number of sexual partners, HIV status, and HR-HPV infection. Smoking was not associated with HR-HPV infection (OR: 1.56, 95% CI: 0.83-2.95) after adjusting for age, sexual risk group, lifetime number of sexual partners, and HIV status. CONCLUSIONS Current smoking was associated with histologically confirmed HSIL but not with HR-HPV infection among this high-risk Hispanic population. Results highlight the need to explore targeted smoking cessation campaigns among populations at higher risk of developing HSIL, as an anal cancer prevention strategy.

Abstract
Our aim was to review the major contributions of studies conducted in different Latin American (LA) countries to the field of human papillomavirus (HPV) epidemiology, natural history, risk of disease, and prevention strategies, mainly in the uterine cervix. Although cytological screening is established in several countries in LA, incidence and mortality rates from cervical cancer (CC) are still extremely high. Finally, data from large cohort studies conducted in LA countries provided seminal data to propose primary and secondary prevention modalities: the HPV vaccine has been introduced in the national immunization programs of several LA countries and multiple screening experiences using HPV testing are under evaluation in the region.

[PMID: 30060856 PMCID: PMC6086131 DOI: 10.1016/j.jadohealth.2018.01.005] [Citation(s) in RCA: 8] [Impact Index Per Article: 1.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 08/03/2017] [Revised: 01/11/2018] [Accepted: 01/11/2018] [Indexed: 11/16/2022]
Abstract
PURPOSE The aims of this study were to determine prevalence of and factors associated with any human papillomavirus (HPV) and vaccine-type HPV among young men after vaccine introduction, stratified by vaccination status. METHODS Young men were recruited from clinical sites from 2013 to 2015, completed a survey, and were tested for 36 anogenital HPV types. We determined factors associated with ≥1 HPV type among all participants, and vaccine-type HPV (HPV6, 11, 16, and/or 18) among all, vaccinated and unvaccinated participants, using multivariable regression. RESULTS Mean age was 21.5 years and 26% had received at least one HPV vaccine dose. HPV prevalence was lower in vaccinated versus unvaccinated young men (50.5% vs. 62.6%, p = .03). HPV positivity was discordant by anogenital site. At both sites, 59.4% were positive for ≥1 HPV type and 26.0% for ≥1 4-valent vaccine type. In multivariable logistic regression, factors associated with ≥1 HPV type among all participants were frequency of oral sex (odds ratio [OR] = 1.80, 95% confidence interval [CI] = 1.00-3.24), recent smoking (OR = 1.84, CI = 1.17-2.90), and sexually transmitted infection history (OR = 1.56, CI = 1.02-2.38). Factors associated with vaccine-type HPV among all participants were white versus black race (OR = 1.91, CI = 1.10-3.34) and gonorrhea history (OR = 2.52, CI = 1.45-4.38); among vaccinated participants were private versus Medicaid insurance (OR = 5.6, CI = 1.46-20.4) and private versus no insurance (OR = 15.9, CI = 3.06-83.3); and among unvaccinated participants was gonorrhea history (OR = 1.83, CI = 1.03-3.24). CONCLUSIONS Anogenital HPV prevalence was high and vaccination rates low among young men 2-4 years after vaccine introduction, underscoring the urgency of increasing vaccination rates and vaccinating according to national guidelines.

Abstract
Male circumcision (MC) is reported to reduce human papillomavirus (HPV) prevalence in men. However, the efficacy remains imprecise. The aim of this study was to conduct a systematic review and meta-analysis to assess the relationship between MC and genital HPV infection and genital warts. PUBMED, EMBASE, and Web of Science were searched from inception to March 22, 2015. We identified 30 papers, including a total of 12149 circumcised and 12252 uncircumcised men who were evaluated for the association of circumcision with genital HPV or genital warts. Compared with men who were not circumcised, circumcised men may have had significantly reduced odds of genital HPV prevalence (odds ratio [OR]: 0.68; 95% confidence interval [95% CI]: 0.56-0.82). There was no significant association between MC and genital HPV acquisition of new infections (OR: 0.99; 95% CI: 0.62-1.60), genital HPV clearance (OR: 1.38; 95% CI: 0.96-1.97), and prevalence of genital warts (OR: 1.17; 95% CI: 0.63-2.17). This meta-analysis suggests that circumcision reduces the prevalence of genital HPV infections. However, no clear evidence was found that circumcision was associated with decreased HPV acquisition, increased HPV clearance, or decreased the prevalence of genital warts. More studies are required to evaluate adequately the effect of MC on the acquisition and clearance of HPV infections and prevalence of genital warts.

Abstract
We developed a dynamic compartmental model to assess the impact of HPV Universal Mass
Vaccination (UMV) with Cervarix™, which offers protection against
HPV16/18 and cross-protection against other cancer-causing types, using up-to-date
efficacy data. Analyses were performed in the UK because of the large amount of high
quality epidemiological data available. For each HPV type/group of types considered, the
model was calibrated to 14 epidemiological datasets (prevalence of HPV infection, cervical
intraepithelial neoplasia (CIN): CIN1, CIN2, CIN3 pre-screening and cervical cancer (CC)
incidence over 10 y post-screening). Impacts of cross-protection, female catch-up
vaccination, and additional male vaccination on oncogenic infections, high-grade CIN
(CIN2+) and CC were evaluated. Our results show that female UMV with 80%
coverage and cross-protection against high-risk types resulted in 81% CIN2+
and 88% CC reductions vs. 57% and 75%, respectively, without
cross-protection. Vaccinating 40% of males and 80% of females was equivalent
to 90% female-only coverage regarding CIN2+ (87% and 87%,
respectively) and CC (93% and 94%, respectively) reductions. Female-only
coverage of 80% substantially reduced male HPV16 and 18 infection due to herd
protection (74% and 89%, respectively). Increasing female coverage to
90% reduced HPV16 and HPV18 infections in males relatively similarly to 80%
female combined with 40% male coverage. Model outcomes strengthen previous
conclusions about the significant added value of Cervarix™
cross-protection for CC prevention, the primary HPV vaccination public health priority.
Regarding female CC prevention and male HPV16/18 infection, small increases in female
coverage induce similar benefits to those achieved by additionally vaccinating men with
40% coverage.

Abstract
This study determined the prevalence and risk factors for genital human papillomavirus (HPV) detection among men who deny ever engaging in penetrative sex. A questionnaire was administered to 4123 men from a cohort study of HPV natural history. Genital exfoliated cells were collected and genotyped for 36 HPV types. Eighty-eight men were classified as virgins. Log-binomial regression models identified factors associated with genital HPV detection. The prevalence of any and high-risk HPV types among 88 male virgins was 25.0% and 18.2%, respectively. Age and smoking status were associated with HPV detection. Further studies are needed to better understand the risk for HPV infection among male virgins.

Abstract
BACKGROUND We studied features that predict the presence of human papillomavirus (HPV) in a new sexual partnership. METHODS We analyzed data from the "HPV Infection and Transmission Among Couples Through Heterosexual Activity" (HITCH) Cohort Study of recently formed partnerships ("dyads"). Women aged 18-24 and their male partners were recruited during 2005-2010 in Montreal, Canada. We tested genital swabs for detection of 36 HPV types. We defined HPV in a partnership as the presence of 1 or more HPV types in either or both partners. Using baseline data from 482 dyads, we calculated prevalence ratios to evaluate candidate risk factors. RESULTS Most women (88%) were unvaccinated. Sixty-seven percent of dyads harbored HPV. For 49% of dyads, both partners were HPV+. HPV was least prevalent in dyads who were in their first vaginal sex relationship (17%) and was virtually ubiquitous in dyads for which both partners had concurrent partners (96%). Dyads that always used condoms with previous partner(s) were 27% (95% confidence interval, 9%-42%) less likely to have HPV. CONCLUSIONS The finding that condom use limited onward spread to future partners is in support of condom promotion to prevent sexually transmitted infections. Ongoing monitoring of HPV in sexual networks is needed, particularly in populations with suboptimal vaccine coverage.

Abstract
Objectives To determine the prevalence of HPV and the risky sexual behaviors associated to it in a sample of male college students, taking into account genotype and viral load. Methods From 2002 to 2003, male students from the Autonomous University of Morelos State completed a questionnaire and provided self-collected genital samples to detect and quantify HPV. We performed a bivariate and a multivariate logistic regression analysis to identify correlates associated with the infection and to assess the viral load as a function of the viral infecting type. The fragments of β-globin gene and L1 of HPV, were amplified, purified and cloned, to evaluate viral load. Results Among 253 subjects, HPV prevalence was 19.4%, and HPV16 was the most common subtype. History of STIs (OR = 4.8; 95% CI 1.2–18.9), contraceptive pill use by female partner (OR = 2.6; 95% CI 1.1–6.3) and exchanging sex for money (OR = 4.9; 95% CI 1.2–20) were associated to the HPV infection. HPV16 viral load was 7.8 copies (HPV/beta-globin) compared to 0.9 copies for other HPV types. Discussion HPV16 displayed the highest viral load, and it was the most prevalent. It was found that using contraceptive pills by female partners was associated with HPV infection.

Abstract
Background To evaluate the pattern of co-infection of human papillomavirus (HPV) types in both sexes in Sweden. Methods Cell samples from genital swabs, first-void urine, and genital swabs immersed in first-void urine were collected in the present cross-sectional High Throughput HPV Monitoring study. Overall, 31,717 samples from women and 9,949 from men (mean age 25) were tested for 16 HPV types using mass spectrometry. Multilevel logistic regression was used to estimate the expected number of multiple infections with specific HPV types, adjusted for age, type of sample, and accounting for correlations between HPV types due to unobserved risk factors using sample-level random effects. Bonferroni correction was used to allow for multiple comparisons (120). Results Observed-to-expected ratio for any multiple infections was slightly above unity in both sexes, but, for most 2-type combinations, there was no evidence of significant departure from expected numbers. HPV6/18 was found more often and HPV51/68 and 6/68 less often than expected. However, HPV68 tended to be generally underrepresented in co-infections, suggesting a sub-optimal performance of our testing method for this HPV type. Conclusions We found no evidence for positive or negative clustering between HPV types included in the current prophylactic vaccines and other untargeted oncogenic types, in either sex.

Abstract
The claim that circumcision reduces the risk of sexually transmitted infections has been repeated so frequently that many believe it is true. A systematic review and meta-analyses were performed on studies of genital discharge syndrome versus genital ulcerative disease, genital discharge syndrome, nonspecific urethritis, gonorrhea, chlamydia, genital ulcerative disease, chancroid, syphilis, herpes simplex virus, human papillomavirus, and contracting a sexually transmitted infection of any type. Chlamydia, gonorrhea, genital herpes, and human papillomavirus are not significantly impacted by circumcision. Syphilis showed mixed results with studies of prevalence suggesting intact men were at great risk and studies of incidence suggesting the opposite. Intact men appear to be of greater risk for genital ulcerative disease while at lower risk for genital discharge syndrome, nonspecific urethritis, genital warts, and the overall risk of any sexually transmitted infection. In studies of general populations, there is no clear or consistent positive impact of circumcision on the risk of individual sexually transmitted infections. Consequently, the prevention of sexually transmitted infections cannot rationally be interpreted as a benefit of circumcision, and any policy of circumcision for the general population to prevent sexually transmitted infections is not supported by the evidence in the medical literature.

Abstract
BACKGROUND Anogenital warts (AGWs) are a common, highly infectious disease caused by the human papillomavirus (HPV), whose high recurrence rates contribute to direct medical costs, productivity loss and increased psychosocial impact. Because of the lack of a systematic review of the epidemiology of AGWs in the literature, this study reviewed the published medical literature on the incidence and prevalence of AGWs. METHODS A comprehensive literature search was performed on the worldwide incidence and prevalence of AGWs between 2001 and 2012 using the PubMed and EMBASE databases. An additional screening of abstracts from relevant sexual health and infectious disease conferences from 2009 to 2011 was also conducted. Only original studies with general adult populations (i.e., at least including ages 20 through 40 years) were included. RESULTS The overall (females and males combined) reported annual incidence of any AGWs (including new and recurrent) ranged from 160 to 289 per 100,000, with a median of 194.5 per 100,000. New AGW incidence rates among males ranged from 103 to 168 per 100,000, with a median of 137 per 100,000 and among females from 76 to 191 per 100,000, with a median of 120.5 per 100,000 per annum. The reported incidence of recurrent AGWs was as high as 110 per 100,000 among females and 163 per 100,000 among males. Incidence peaked before 24 years of age in females and between 25 and 29 years of age among males. The overall prevalence of AGWs based on retrospective administrative databases or medical chart reviews or prospectively collected physician reports ranged from 0.13% to 0.56%, whereas it ranged from 0.2% to 5.1% based on genital examinations. CONCLUSIONS The literature suggests that AGWs are widespread and the prevalence depends on study methodology as suggested by higher rates reported from routine genital examinations versus those from treatment records. However, there remains a need for more population-based studies from certain regions including Africa, Latin America and Southern Asia to further elucidate the global epidemiology of this disease.

Abstract
OBJECTIVE Human Papillomavirus (HPV) infection in men may produce cancer and other major disorders. Men play an important role in the transmission of the virus and act as a reservoir. The aim of this study was to determine the HPV-genotypes and their prevalence in a group of men attending a Sexually Transmitted Infection service. PATIENTS AND SAMPLES: Between July 2002 and June 2011, 1392 balanopreputial, 435 urethral, 123 anal, and 67 condyloma lesions from 1551 men with a mean age of 35.8±11.3 years old (range: 17-87) were collected for HPV-DNA testing. METHODS A fragment of the L1-gene and a fragment of the E6/E7-genes were amplified by PCR. Positive samples were typed by hybridization. RESULTS The HPV genome was detected in 36.9% (486/1318) balanopreputial and in 24.9% (101/405) urethral (p<0.0001) swabs from 38.1% (538) of 1469 men. Co-infections were present in 5.4% (80/1469) of cases. HPV was found in 43.9% (373/850) of men younger than 35 vs. 31.7% (187/589) of men aged >35. HPV was found in 59.4% (104) of 165 men with lesions (macroscopic or positive peniscopy), and in 22.8% (61/267) without clinical alterations. HPV was also detected in 71.4% (40/56) men with condylomata and in 58.7% (64/109) of men with positive peniscopy. CONCLUSIONS HPV prevalence in men was high and decreased with age. HPV was found more frequently in balanopreputial than in urethral swabs. There was a low rate of co-infections. Low-risk HPV vaccine genotypes were the most recurrent especially in younger. Although HPV has been associated with clinical alterations, it was also found in men without any clinical presentation. Inclusion of men in the national HPV vaccination program may reduce their burden of HPV-related disease and reduce transmission of the virus to non-vaccinated women.

Abstract
BACKGROUND Accumulated evidence from epidemiological studies and more recently from randomized controlled trials suggests that male circumcision (MC) may substantially protect against genital HPV infection in men. The purpose of this study was to assess the association between MC and genital HPV infection in men in a large multinational study. METHODS A total of 4072 healthy men ages 18-70 years were enrolled in a study conducted in Brazil, Mexico, and the United States. Enrollment samples combining exfoliated cells from the coronal sulcus, glans penis, shaft, and scrotum were analyzed for the presence and genotyping of HPV DNA by PCR and linear array methods. Prevalence ratios (PR) were used to estimate associations between MC and HPV detection adjusting for potential confounders. RESULTS MC was not associated with overall prevalence of any HPV, oncogenic HPV types or unclassified HPV types. However, MC was negatively associated with non-oncogenic HPV infections (PR 0.85, 95% confident interval: 0.76-0.95), in particular for HPV types 11, 40, 61, 71, and 81. HPV 16, 51, 62, and 84 were the most frequently identified genotypes regardless of MC status. CONCLUSIONS This study shows no overall association between MC and genital HPV infections in men, except for certain non-oncogenic HPV types for which a weak association was found. However, the lack of association with MC might be due to the lack of anatomic site specific HPV data, for example the glans penis, the area expected to be most likely protected by MC.

Abstract
BACKGROUND Knowledge about the incidence, clearance, and factors associated with human papilloma virus (HPV) infection in men is lacking, and much of what is available focuses on high-risk groups. METHODS A prospective cohort study was carried out with 504 heterosexual males from Mexico State, Mexico. Participants were monitored for 4 years at intervals of approximately 4 months, with a median total duration of follow-up of 19.8 months. The presence of cervical HPV in female sexual partners was evaluated as a risk factor. HPV DNA testing was conducted using the polymerase chain reaction technique. Risk factors associated with the incidence and clearance of HPV infection were evaluated through survival analysis. RESULTS The cumulative incidence of infection with any HPV type at 12 months was 15% [95% confidence interval (CI), 0.12-0.20]. About 72% of men with incident HPV cleared the infection by 12 months. The presence of cervical HPV in a man's female sex partner was the main determinant for males acquiring HPV infection of any type [adjusted HR (AHR), 2.1; 95% CI, 1.1-3.8] and oncogenic HPV infection (AHR, 4.1; 95% CI, 2.1-8.0), while having a history of anal sexual relations with women was statistically associated with acquiring nononcogenic HPV (AHR, 1.8; 95% CI, 1.1-2.9). CONCLUSIONS AND IMPACT The incidence of genital HPV infection in this population is relatively low, with relatively quick acquisition and clearance rates. Cervical HPV infection in men's female sexual partners was the main risk factor for genital HPV infection in men.

Abstract
BACKGROUND Human papillomavirus (HPV) infection is the principal cause of invasive cervical cancer. There is some evidence that male circumcision (MC) may protect against HPV infection and related disease in both men and women. The purpose of this study was to conduct a systematic review of the literature to assess the association between MC and genital HPV infection indicators including genital warts. METHODS A systematic search of Medline was conducted to identify all relevant studies from February 1971 to August 2010. Effect estimates were included in random effects models. RESULTS A total of 21 studies with 8046 circumcised and 6336 uncircumcised men were included in the meta-analysis. MC was associated with a statistically significant reduced odds of genital HPV prevalence (odds ratio = 0.57, 95% confidence interval: 0.42-0.77). This association was also observed for genital high-risk HPV prevalence in 2 randomized controlled trials (odds ratio = 0.67, 95% confidence interval: 0.54-0.82). No associations were found between MC and genital HPV acquisition of new infections, genital HPV clearance, or genital warts. CONCLUSIONS This meta-analysis shows a robust inverse association between MC and genital HPV prevalence in men. However, more studies are needed to adequately assess the effect of MC on the acquisition and clearance of HPV infections. MC could be considered as an additional one-time preventative intervention likely to reduce the burden of HPV-related diseases both in men and women, particularly among those countries in which HPV vaccination programs and cervical screening are not available.

Abstract
The goal of this review is to summarise epidemiological data that support an understanding of the natural history of anal human papillomavirus (HPV) among women and men having sex with women (MSW). HPV is a common infection of the anal canal among women and MSW. Although there have been a limited number of studies to date, both oncogenic and nononcogenic HPV genotypes commonly occur among these populations even when individuals do not report receptive anal sex. Genotype distribution is quite diverse, with recent studies typically detecting more than two dozen genotypes in the anal canal in samples of women and MSW. Factors most consistently associated with HPV in the anal canal among both women and MSW are lifetime number of sexual partners and detection of HPV at the genitals. The common finding of genotypic concordance between the genitals and anal canal in women and MSW, and the infectious nature of HPV, in addition to a limited number of studies offering empirical evidence of anal-to-genital self-inoculation and evidence of HPV hand carriage, may help explain the detection of HPV in the anal canal outside the context of receptive anal sex. HPV vaccination has been shown to reduce anal HPV infection among women and is also a promising prevention strategy among MSW.

Abstract
BACKGROUND We systematically reviewed the evidence for an association between male circumcision and Human Papillomavirus (HPV) infection and genital warts in men. METHODS PubMed and Embase were searched to 15 September 2010. The measure of effect was the adjusted odds ratio (OR) or rate ratio (RR) when present and the crude estimate otherwise. Random effects meta-analyses were used to calculate summary measures of effect. RESULTS We identified 23 papers about the association between circumcision and HPV DNA. Circumcised men were less likely to have prevalent genital HPV infection than uncircumcised men (summary OR, 0.57, 95% confidence interval [CI], 0.45-0.71) with between-study heterogeneity (P-heterogeneity = 0.006; I(2) = 50.5%; 19 studies). Similar summary associations were seen in clinical and methodological subgroups. The effect of circumcision was stronger at the glans/corona (OR, 0.47; 95% CI, 0.37-0.60) and urethra (OR, 0.35; 95% CI, 0.12-1.05) compared with sites more distal to the foreskin. There was weak evidence that circumcision was associated with decreased HPV incidence (summary RR, 0.75, 95% CI, 0.57-0.99; 3 studies) and increased HPV clearance (summary RR, 1.33; 95% CI, 0.89-1.98; 3 studies) but no evidence of an association with prevalent genital warts (OR, 0.93, 95% CI, 0.65-1.33; 15 studies). CONCLUSIONS Several countries are expanding access to voluntary medical male circumcision to reduce HIV prevalence. This could provide additional benefit in reducing HPV prevalence.

Abstract
Human papillomavirus (HPV) is highly prevalent in men and there is an interest in further understanding the relationship between HPV infection and disease in men, including the development of genital warts, penile intraepithelial neoplasia and invasive penile carcinomas. Genital warts are caused by HPV 6/11 and are the most common clinical manifestation of HPV in men. Though they are benign and not associated with mortality, they are a source of psychosocial distress and physical discomfort. HPV infection can also develop into invasive penile carcinoma which is associated with morbidity and mortality. Approximately 40% of invasive penile carcinomas are attributable to HPV with HPV 16, 18, and 6/11 being the genotypes most commonly detected in penile tumors. Penile carcinomas of the basaloid and warty histologic subtypes are most likely to test positive for HPV. In addition to HPV infection, the risk factors most strongly associated with penile cancer are lack of neonatal circumcision, phimosis (the inability of uncircumcised men to fully retract the foreskin), and anogenital warts. Male vaccination with the quadrivalent HPV vaccine that protects against HPV 6/11/16/18 has been shown to significantly reduce HPV-associated anogenital infection and disease in men. If the quadrivalent vaccine is successfully disseminated to large segments of the young male population, there is the potential for substantial reduction in genital HPV infection and related lesions in men.

Abstract
OBJECTIVE To evaluate clustering patterns of prevalent infection with multiple human papillomavirus (HPV) types in 3677 men from the HPV in Men (HIM) study. METHODS HPV testing was performed in samples combined from the glans penis/coronal sulcus, the shaft, and the scrotum by Linear Array methodology. Linear Array uses a mixed probe to assess HPV52 positivity, which limits the assay's ability to determine HPV52 status in the presence of HPV33, 35, or 58. Logistic regression was used to model type-specific HPV positivity, adjusted for age, study area, lifetime number of sexual partners, and specific HPV type prevalence. Participant-level random effects were added to represent unobservable risk factors common to all HPV types. RESULTS The observed-to-expected ratio for infections with ≥ 3 types was 1.09 (95% credible interval, 1.04-1.14). For the majority of 2-type combinations, no evidence was found of a significant departure of the observed from the expected number. An apparent clustering of HPV52 with HPV35 or 58 was observed, because of limitation in the ability of Linear Array to define HPV52 positivity. CONCLUSIONS Our study showed that, despite obvious anatomical differences, HPV coinfections do seem to occur at random in the male external genitalia as in the female cervix.

Abstract
PURPOSE Global data on age-specific prevalence of human papillomavirus (HPV) infection in males, especially for oncogenic HPV types 16 and 18, are essential for future efforts to prevent HPV-related diseases, including expanded access to HPV prophylactic vaccines for boys and young men. METHODS A systematic review of peer-reviewed publications was conducted to summarize worldwide data on genital HPV-DNA prevalence in men. Studies using polymerase chain reaction or hybrid capture detection assays were included. RESULTS Approximately 6,600 abstracts were identified. Of them, 64 reported age-specific HPV prevalence and were included in the review. Of these, 38 were from populations at high risk of HPV infections, such as sexually transmitted infection clinic attendees, human immunodeficiency virus-positive males, and male partners of women with HPV infection or abnormal cytology. The largest proportions of studies were from Europe (38%) and North America (25%), with smaller proportions from Central and South America (19%), Asia (11%), and Africa (5%). Across all regions, data on HPV prevalence were generally limited to men >18 years of age. HPV prevalence was high among sexually active men in all regions but with considerable variation, from 1% to 84% among low-risk men and from 2% to 93% among high-risk men. Peak HPV prevalence spanned a wide range of ages and was generally not concentrated in the younger age groups. Age-specific prevalence curves were relatively flat or declined only slightly following peak prevalence. CONCLUSIONS Genital HPV infection in men varies widely, both between and within high- and low-risk groups and by geographic region. Compared with that in women, HPV prevalence in men seems to peak at slightly older ages and remains constant or decreases slightly with increasing age, suggesting persistent HPV infection or a higher rate of reinfection.

Abstract
Male circumcision protects against cancer of the penis, the invasive form of which is a devastating disease confined almost exclusively to uncircumcised men. Major etiological factors are phimosis, balanitis, and high-risk types of human papillomavirus (HPV), which are more prevalent in the glans penis and coronal sulcus covered by the foreskin, as well as on the penile shaft, of uncircumcised men. Circumcised men clear HPV infections more quickly. Phimosis (a constricted foreskin opening impeding the passage of urine) is confined to uncircumcised men, in whom balanitis (affecting 10%) is more common than in circumcised men. Each is strongly associated with risk of penile cancer. These findings have led to calls for promotion of male circumcision, especially in infancy, to help reduce the global burden of penile cancer. Even more relevant globally is protection from cervical cancer, which is 10-times more common, being much higher in women with uncircumcised male partners. Male circumcision also provides indirect protection against various other infections in women, along with direct protection for men from a number of genital tract infections, including HIV. Given that adverse consequences of medical male circumcision, especially when performed in infancy, are rare, this simple prophylactic procedure should be promoted.

Abstract
Background. Low-Risk Human Papillomavirus (LR-HPV) genotypes 6 and 11 cause genital warts. This study investigated the association of LR-HPV infection with male circumcision (MC). Methods. We used data from the South African MC trial conducted among young men. Urethral swabs, collected among intervention (circumcised) and control (uncircumcised) groups, were analyzed using HPV linear array. Adjusted LR-HPV prevalence rate ratio (aPPR) and Poisson mean ratio (aPMR) of number of LR-HPV genotypes were estimated using log-Poisson regression, controlling for background characteristics, sexual behaviour, and HIV and HSV-2 statuses. Results. Compared to controls, LR-HPV prevalence and mean number of genotypes were significantly lower among the intervention group ((8.5% versus 15.8%; aPRR: 0.54, P < .001) and (0.33 versus 0.18; aPMR: 0.54, P < .001), resp.). Mean number of LR-HPV genotypes increased with number of lifetime sexual partners and decreased with education level and consistent condom use. Conclusions. This study shows a reduction in LR-HPV infection among circumcised men.

Abstract
Accurate knowledge about human sexual behaviors is important for increasing our understanding of human sexuality; however, there have been few studies assessing the reliability of sexual behavior questionnaires designed for community samples of adult men. A test-retest reliability study was conducted on a questionnaire completed by 334 men who had been recruited in Tucson, Arizona. Reliability coefficients and refusal rates were calculated for 39 non-sexual and sexual behavior questionnaire items. Predictors of unreliable reporting for lifetime number of female sexual partners were also assessed. Refusal rates were generally low, with slightly higher refusal rates for questions related to immigration, income, the frequency of sexual intercourse with women, lifetime number of female sexual partners, and the lifetime number of male anal sex partners. Kappa and intraclass correlation coefficients were substantial or almost perfect for all non-sexual and sexual behavior items. Reliability dropped somewhat, but was still substantial, for items that asked about household income and the men's knowledge of their sexual partners' health, including abnormal Pap tests and prior sexually transmitted diseases (STD). Age and lifetime number of female sexual partners were independent predictors of unreliable reporting while years of education was inversely associated with unreliable reporting. These findings among a community sample of adult men are consistent with other test-retest reliability studies with populations of women and adolescents.

Abstract
Background Although human papillomavirus (HPV) infection in heterosexual couples has been sparsely studied, it is relevant to understand disease burden and transmission mechanisms. The present study determined the prevalence and concordance of type-specific HPV infection as well as the determinants of infection in heterosexual couples in a rural area of Mexico. Methods A cross-sectional study was conducted in 504 clinically healthy heterosexual couples from four municipalities in the State of Mexico, Mexico. HPV testing was performed using biotinylated L1 consensus primers and reverse line blot in cervical samples from women and in genital samples from men. Thirty-seven HPV types were detected, including high-risk oncogenic types and low-risk types. Multivariate logistic regression models were utilized to evaluate factors associated with HPV. Results The prevalence of HPV infection was 20.5% in external male genitals and 13.7% in cervical samples. In 504 sexual couples participating in the study, concordance of HPV status was 79%; 34 partners (6.7%) were concurrently infected, and 21 out of 34 partners where both were HPV positive (61.8%) showed concordance for one or more HPV types. The principal risk factor associated with HPV DNA detection in men as well as women was the presence of HPV DNA in the respective regular sexual partner (OR = 5.15, 95%CI 3.01-8.82). In men, having a history of 10 or more sexual partners over their lifetime (OR 2.5, 95%CI 1.3 - 4.8) and having had sexual relations with prostitutes (OR 1.7, 95%CI 1.01 - 2.8) increased the likelihood of detecting HPV DNA. Conclusions In heterosexual couples in rural regions in Mexico, the prevalence of HPV infection and type-specific concordance is high. High-risk sexual behaviors are strong determinants of HPV infection in men.

Abstract
BACKGROUND We evaluated the influence of the partner's human papillomavirus (HPV) status and sexual practices on prevalent HPV infection among new couples to study HPV transmission. METHODS Women attending university or college in Montreal, Canada, and their male partners (N = 263 couples) were enrolled in 2005-2008. HPV typing was done in self-collected vaginal swabs and clinician-collected penis and scrotum swabs. The outcome measures were overall and type-specific HPV prevalence. RESULTS HPV was detected in 56% of women and men. Prevalence was higher among persons with infected partners (85%) than in those whose partners were negative (19%). Type-specific detection was substantially higher among women (OR = 55.2, 95% CI: 38.0-80.1) and men (OR = 58.7, 95% CI: 39.8-86.3) if their partner harbored the type under consideration. Prevalence among women and men with 10 or more lifetime partners was 15.4 (95% CI: 5.9-40.2) and 9.5 (95% CI: 4.4-19.8) times higher than among those with 1 partner. Frequent condom use was protective in men, particularly if his partner was HPV-infected (OR = 0.64, 95% CI: 0.50-0.82). This effect was attenuated among women with an infected partner (OR = 0.88, 95% CI: 0.69-1.11). CONCLUSIONS The current partner's status was the most important risk factor for prevalent HPV infection. Condoms exerted a stronger protective effect among men than among women.

Abstract
Human papillomavirus (HPV) causes cervical cancer and is strongly associated with other anogenital cancers. Multiple-type HPV infection has been associated with lengthier infection and precancerous lesions. Little is known about multiple-type HPV prevalence and associated factors in men. We examined the prevalence of and risk factors for multiple-type HPV in primarily asymptomatic men. Detection of 37 HPV types in male anogenital epithelium and semen was completed in 463 men in two U.S. cities. The proportions of men with multiple HPV of any type and with multiple oncogenic or nononcogenic types were calculated. Factors associated with multiple HPV were evaluated using multinomial logistic regression. Overall, 22.9% of men had multiple-HPV, 8.6% of men had multiple oncogenic types, and 13.4% had multiple nononcogenic types. Greater proportions of samples at the shaft, glans/corona, and scrotum had multiple HPV types (18.7%, 12.8%, and 7.3%, respectively) than did other anogenital sites (all < or =2.8%). Factors independently associated with multiple-type HPV were Hispanic ethnicity [adjusted odds ratio (AOR), 2.45; 95% confidence interval (95% CI), 1.05-5.67], concurrent detection of genital warts (AOR, 10.40; 95% CI, 1.12-96.6), smoking > or =10 cigarettes/d (AOR, 3.00; 95% CI, 1.07-8.43), greater lifetime number of female sexual partners (AOR, 13.73 for > or =21 versus 1-5; 95% CI, 5.34-35.3), and condom use less than half the time (AOR, 2.03; 95% CI, 1.07-3.84). Detection of multiple HPV types in this study of primarily asymptomatic men was common, particularly at external genital sites. Lifetime number of female sex partners, condom use, and smoking were modifiable factors associated with multiple HPV.

Abstract
Circumcision has been reported to protect against infection with human papillomavirus (HPV) in men, but results have been inconsistent. We followed males in a birth cohort born in Dunedin, New Zealand, in 1972 and 1973 from age 3 to 32 years. Seropositivity at age 32 years for the oncogenic types HPV-16 and 18, and the nononcogenic types 6 and 11, was studied in relation to maternal reports of circumcision status at age 3 for 450 men. Seropositivity to any of these types was associated with lifetime number of sexual partners (P = 0.03), and lower moral-religious emphasis of the family of origin (P < 0.001). Circumcision was not found to be protective, with the adjusted odds ratio (95% confidence interval) for HPV6/11/16/18 seropositivity among the circumcised compared with the uncircumcised being 1.4 (0.89-2.2).

Abstract
OBJECTIVE To assess Human Papillomavirus (HPV) type distribution among men ages 18 years and older recruited from three different countries utilizing a common protocol for sampling HPV detection, and to evaluate whether HPV detection differs by age and country. MATERIAL AD METHODS: The study protocol includes a pre-enrollment run-in visit, a baseline (enrollment) visit, and nine additional visits after enrollment scheduled six months apart. For this analysis, the first 1160 men who completed both the run-in and baseline visit were included. To maximize sampling and prevent fraying of applicators, three different applicators were utilized to sample the external genitalia of participants among different anatomic sites. These samples were later combined to form a single sample for the detection of HPV using polymerase chain reaction (PCR) for amplification of a fragment of the HPV L1 gene. RESULTS Among 1160 men from Brazil, Mexico, and the United States (U.S.), overall HPV prevalence was 65.2%; with 12.0% oncogenic types only, 20.7% non-oncogenic types only, 17.8% both oncogenic and non-oncogenic, and 14.7% unclassified infections. Multiple HPV types were detected in 25.7% of study participants. HPV prevalence was higher in Brazil (72.3%) than in the U.S. (61.3%) and Mexico (61.9%). HPV 16 (6.5%), 51 (6.5%), and 59 (5.3%) were the most commonly detected oncogenic infections, and HPV 84 (7.7%), 62 (7.3%), and 6 (6.6%) were the most commonly detected non-oncogenic infections. Overall HPV prevalence was not associated with age. However, significant associations with age were observed when specific categories of oncogenic, non-oncogenic, and unclassified HPV infections were considered. CONCLUSIONS Studies of HPV type distribution among a broad age range of men from multiple countries is needed to fill the information gap internationally with respect to our knowledge of HPV infection in men.

Abstract
BACKGROUND Male circumcision may lower men's risk of human papillomavirus (HPV) infection and reduce transmission to sex partners. Reported associations between circumcision and HPV infection in men have been inconsistent. METHODS Four hundred sixty-three men in 2 US cities were tested at 6 anogenital sites and in semen for 37 types of HPV. Men were eligible if they reported sex with a woman within the past year, no history of genital warts or penile or anal cancer, and no current diagnosis of a sexually transmitted infection. Participants completed a self-administered questionnaire. Circumcision status was assessed by the study clinician. Logistic regression was used to examine associations between circumcision and HPV detection at each site and in semen, with adjustment for potential confounders. RESULTS Seventy-four men (16.0%) were uncircumcised. Adjusted odds ratios (AORs) for any HPV genotype and circumcision were 0.53 (95% confidence interval [CI], 0.28-0.99) for any anatomic site/specimen, 0.17 (95% CI, 0.05-0.56) for the urethra, 0.44 (95% CI, 0.23-0.82) for the glans/corona, and 0.53 (95% CI, 0.28-0.99) for the penile shaft. AORs were <1.0 but not statistically significant for the scrotum, semen, anal canal, and perianal area. CONCLUSIONS Circumcision may be protective against HPV infection of the urethra, glans/corona, and penile shaft.

Abstract
BACKGROUND A causal association links high-risk human papillomavirus (HR-HPV) and cervical cancer, which is a major public health problem. The objective of the present study was to investigate the association between male circumcision (MC) and the prevalence of HR-HPV among young men. METHODS We used data from a MC trial conducted in Orange Farm, South Africa, among men aged 18-24 years. Urethral swab samples were collected during a period of 262 consecutive days from participants in the intervention (circumcised) and control (uncircumcised) groups who were reporting for a scheduled follow-up visit. Swab samples were analyzed using polymerase chain reaction. HR-HPV prevalence rate ratios (PRRs) were assessed using univariate and multivariate log Poisson regression. RESULTS In an intention-to-treat analysis, the prevalences of HR-HPV among the intervention and control groups were 14.8% (94/637) and 22.3% (140/627), respectively, with a PRR of 0.66 (0.51-0.86) (P = .002). Controlling for propensity score and confounders (ethnic group, age, education, sexual behavior [including condom use], marital status, and human immunodeficiency virus status) had no effect on the results. CONCLUSIONS This is the first randomized controlled trial to show a reduction in the prevalence of urethral HR-HPV infection after MC. This finding explains why women with circumcised partners are at a lower risk of cervical cancer than other women.

Abstract
There is growing interest in understanding human papillomavirus (HPV) infection and related disease among men. To date there have been numerous studies reporting HPV DNA prevalence among men from several different countries, however, few have incorporated multivariable analyses to determine factors independently associated with male HPV detection. The purpose of this study was to assess the factors independently associated with HPV detection in men ages 18-70 years residing in Brazil (n = 343), Mexico (n = 312), and the United States (US) (n = 333). In samples combined from the coronal sulcus, glans penis, shaft, and scrotum, we evaluated factors associated with any, oncogenic, and nononcogenic HPV infections. In multivariable analyses, detection of any HPV infection was significantly associated with reported race of Asian/Pacific Islander, lifetime and recent number of sexual partners, and having sex in the past 3 months. Oncogenic HPV detection was independently associated with lifetime and recent number of sexual partners, and having sex in the past 3 months. NonOncogenic HPV infection was independently associated with lifetime number of sexual partners. Circumcision, assessed by clinical examination, was associated with reduced risk of HPV detection across all categories of HPV evaluated. HPV detection in men in the current study was strongly related to sexual behavior and circumcision status. Interventions such as circumcision may provide a low-cost method to reduce HPV infection.

Abstract
BACKGROUND Invasive squamous cell carcinoma (SCC) of the penis is rare in the United States. Although human papillomavirus (HPV) infection is an established etiologic agent in at least 40% of penile SCCs, relatively little is known about the epidemiology of this malignancy. METHODS Population-based data from the National Cancer Institute's Surveillance, Epidemiology and End Results (SEER) program, the Centers for Disease Control and Prevention's National Program for Cancer Registries, and the National Center for Health Statistics were used to examine invasive penile SCC incidence and mortality in the United States. SEER data were used to examine treatment of penile SCC. RESULTS From 1998 to 2003, 4967 men were diagnosed with histologically confirmed invasive penile SCC in the United States, representing less than 1% of new cancers in men. The annual, average age-adjusted incidence rate was 0.81 cases per 100,000 men, and rates increased steadily with age. Overall, penile SCC incidence was comparable in whites and blacks, but approximately 2-fold lower in Asians/Pacific Islanders. Rates among Hispanics were 72% higher compared with non-Hispanics. Blacks compared with whites and Asians/Pacific Islanders and Hispanics compared with non-Hispanics were diagnosed at significantly younger ages. Higher rates of mortality were also observed among blacks compared with whites and Hispanics compared with non-Hispanics. Penile SCC incidence and mortality were elevated in Southern states and in regions of low socioeconomic status (SES). Some histologic and anatomic site differences were observed by race and ethnicity. Treatment of penile SCC varied with age, stage, and other tumor characteristics. CONCLUSIONS There are considerable disparities in invasive penile cancer incidence and mortality in the United States. Key risk factors for excess incidence include Hispanic ethnicity and residence in the South and in low SES regions. Risks for excess mortality include these factors in addition to black race. Decreases in penile cancer incidence and mortality in the United States may be realized in the future as the indirect result of prophylactic HPV vaccination of females. Further research is needed to better understand the epidemiology of penile cancer including the role of HPV.

Abstract
BACKGROUND A wide spectrum of human papillomavirus (HPV) types can infect the male genitalia. An HPV vaccine covering HPV6 and 11 is now available. Detailed data on the distribution of these two types in anogenital warts is needed to assess the potential benefits of the vaccine. STUDY DESIGN Anogenital wart specimens collected from 130 Chinese men were examined for HPV-type distribution by a method that covers a broad spectrum of high- and low-risk HPVs, and able to reveal multiple types from a single specimen. RESULTS Forty-four (33.8%) of the 130 specimens had a coinfection with multiple HPV types. In 63.1% of cases, only HPV6 and/or HPV11 were/was found. In 26.2% of cases, HPV6 and/or HPV11 were/was found together with one or more other HPV types. In 10.8% of specimens, only non-6/11 HPV types were found. HPV16 and/or 18 were/was found in 12 (9.2%) specimens, with majority (8/12, 66.7%) of which existed as coinfections with HPV6/11. Other HPV types found included HPV39, 51, 52, 55, 59, 61, 62, 68, 58, 72, 81, 83, 84 and CP6108. CONCLUSIONS A substantial proportion of HPV6/11-positive male anogenital warts are coinfected with other HPV types. The efficacy of HPV6/11 vaccine for preventing these lesions needs to be defined before the benefits of vaccinating men can be precisely assessed.

Abstract
Male sexual behavior influences the rates of cervical dysplasia and invasive cervical cancer, as well as male human papillomavirus (HPV) infection and disease. Unfortunately, little is known regarding male HPV type distribution by age and across countries. In samples combined from the coronal sulcus, glans penis, shaft, and scrotum of 1,160 men from Brazil, Mexico, and the United States, overall HPV prevalence was 65.2%, with 12.0% oncogenic types only, 20.7% nononcogenic types only, 17.8% both oncogenic and nononcogenic, and 14.7% unclassified infections. Multiple HPV types were detected in 25.7% of study participants. HPV prevalence was higher in Brazil (72.3%) than in the United States (61.3%) and Mexico (61.9%). HPV16 (6.5%), HPV51 (5.3%), and HPV59 (5.3%) were the most commonly detected oncogenic infections, and HPV84 (7.7%), HPV62 (7.3%), and HPV6 (6.6%) were the most commonly detected nononcogenic infections. Overall HPV prevalence was not associated with age. However, significant associations with age were observed when specific categories of HPV, nononcogenic, and unclassified HPV infections were considered. Studies of HPV type distribution among a broad age range of men from multiple countries is needed to fill the information gap internationally with respect to our knowledge of HPV infection in men.

Abstract
The incidence of cervical cancer in Latin America and the Caribbean (LAC) is among the highest in the world. Because there are major demographic shifts happening in LAC countries (population growth, urbanization and ageing) cervical cancer incidence and mortality will likely continue to be a significant public health problem. Overall human papillomavirus (HPV) prevalence in the LAC general population has been found to be 2-fold higher than the average worldwide prevalence. The large HPV and cancer burden may be explained by the highly prevalent HPV variants of HPV types -16 and 18, which have an increased oncogenic potential. Given the major mode of transmission of genital HPV is sexual, certain, patterns of sexual behaviour (early age at first sexual intercourse, number of sexual partners and sexual behaviour of the partner) are associated with an increased risk of HPV genital acquisition. Although HPV infection is necessary for carcinogenesis, certain co-factors (high parity, long term use of oral contraceptives, smoking and co-infection with the human immunodeficiency virus (HIV)) help in the progression from infection to cancer. Many studies that have contributed to this evidence have been carried out in LAC and are reviewed and summarised in this article. Since HPV vaccines will likely take years to implement, and many more years to show impact on disease, cervical cancer screening programmes remain as the key intervention to control disease in LAC in the years to come.

Abstract
In US men, the incidence of anal cancer, the primary cause of which is human papillomavirus (HPV) infection, has increased almost 3-fold in 3 decades; however, little is known about the epidemiology of anal HPV infection, especially in heterosexual men. In 2 US cities, behavioral data and anal biological specimens were collected from 253 men who acknowledged having engaged in sexual intercourse with a woman during the preceding year. On the basis of DNA analysis, overall prevalence of anal HPV infection was found to be 24.8% in 222 men who acknowledged having had no prior sexual intercourse with men. Of the men with anal HPV infection, 33.3% had an oncogenic HPV type. Risk factors independently associated with anal HPV were lifetime number of female sex partners and frequency of sex with females during the preceding month. These results suggest that anal HPV infection may be common in heterosexual men.

Abstract
BACKGROUND Lack of circumcision has been identified as a risk factor for male genital human papillomavirus (HPV) infection, although this association has not been consistently supported. METHODS Specimens for HPV testing were collected from a cohort of 379 (primarily heterosexual) adult males. HPV prevalence in the glans penis and coronal sulcus, penile shaft, scrotum, semen, and urine was compared by circumcision status. RESULTS Overall, HPV DNA prevalence ranged from 6% in semen to 52% in the penile shaft. The prevalence of any HPV infection in the glans/corona was significantly higher in uncircumcised men (46%) than in circumcised men (29%) (odds ratio [OR], 1.96 [95% confidence interval (CI), 1.02-3.75], adjusted for demographic characteristics and sexual history). Uncircumcised men also had an increased risk of oncogenic HPV infection (adjusted OR, 2.51 [95% CI, 1.11-5.69]) and infection with multiple HPV types (adjusted OR, 3.56 [95% CI, 1.50-8.50]). Among uncircumcised men, HPV prevalence in the foreskin (44%) was comparable to that in the glans/corona, and type-specific positivity was observed between the 2 sites (kappa=0.52). CONCLUSIONS Uncircumcised men have an increased risk of HPV infection, including with oncogenic HPV, specifically localized to the glans/corona, possibly because of its proximity to the foreskin, which may be particularly vulnerable to infection.

Abstract
This article reviews the findings of three trials of male circumcision for HIV prevention, with emphasis on the public health impact, cultural and safety concerns, implications for women, and the challenges of roll out. Three randomized trials in Africa demonstrated that adult male circumcision reduces HIV acquisition by 50% to 60%. As circumcision provides only partial protection, higher risk behaviors could nullify circumcision's effect. Additionally, circumcision among HIV-infected men does not directly reduce male-to-female HIV transmission among discordant couples, according to the results of a recent Ugandan study. The roll-out or full-scale implementation requires committed expansion into existing HIV prevention programs. Efforts should include attention to safety, implications for women, and risk compensation. Rapid, careful establishment of circumcision services is essential to optimize HIV prevention in countries with the highest prevalence.
