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.

Abstract
Men should not be overlooked in research on human papillomavirus (HPV) and its associated genital diseases. This is because men infected with HPV are not only at higher risk of genital cancers, but also increase their partners' risk of HPV infection and reinfection through sexual contact. Herein, we summarized the state of knowledge regarding the prevention and treatment of HPV infection in men as well as the possible effects of the prevention and treatment of HPV in men on their female partners. Condom use, smoking cessation, male circumcision, and HPV vaccination for men each play an important role in preventing HPV infection within heterosexual couples. Additionally, men could choose to test for certain types of HPV, such as the oncogenic HPV16 or HPV18 strains, as part of a routine screening program when their partner is positive for HPV. Although there is no recognized treatment for HPV infection as of yet, immunotherapy drugs, such as toll-like receptor agonists, therapeutic HPV vaccines, and immune checkpoint inhibitors, have shown promising results in clinical trials and in actual clinical practice. HPV infection in men also increases the risk of cervical cancer in their female partners. Because of the high partner concordance for HPV demonstrated in prior research, the prevention and treatment of HPV in men should be explored more comprehensively in future research.

Abstract
Population-based studies in high-income countries have failed to find that male circumcision protects against sexually transmitted infections. Using evidence from several sources, we show that male circumcision does protect against HIV during insertive intercourse for men who have sex with men.

Abstract
The aim was (1) to perform an up-to-date systematic review of the male circumcision (MC) literature and (2) to determine the number of adverse medical conditions prevented by early MC in Australia. Searches of PubMed using "circumcision" with 39 keywords and bibliography searches yielded 278 publications meeting our inclusion criteria. Early MC provides immediate and lifetime benefits, including protection against: urinary tract infections, phimosis, inflammatory skin conditions, inferior penile hygiene, candidiasis, various STIs, and penile and prostate cancer. In female partners MC reduces risk of STIs and cervical cancer. A risk-benefit analysis found benefits exceeded procedural risks, which are predominantly minor, by approximately 200 to 1. It was estimated that more than 1 in 2 uncircumcised males will experience an adverse foreskin-related medical condition over their lifetime. An increase in early MC in Australia to mid-1950s prevalence of 85% from the current level of 18.75% would avoid 77,000 cases of infections and other adverse medical conditions over the lifetime for each annual birth cohort. Survey data, physiological measurements, and the anatomical location of penile sensory receptors responsible for sexual sensation indicate that MC has no detrimental effect on sexual function, sensitivity or pleasure. US studies found that early infant MC is cost saving. Evidence-based reviews by the AAP and CDC support early MC as a desirable public health measure. Although MC can be performed at any age, early MC maximizes benefits and minimises procedural risks. Parents should routinely be provided with accurate, up-to-date evidence-based information in an unbiased manner early in a pregnancy so that they have time to weigh benefits and risks of early MC and make an informed decision should they have a son. Parental choice should be respected. A well-trained competent practitioner is essential and local anaesthesia should be routinely used. Third party coverage of costs is advocated.

Abstract
OBJECTIVE Human papillomavirus (HPV)-associated uteri cervix carcinoma continues to be the 2nd highest cause of death among women in India. This study aims to identify the mode of HPV transmission in different communities such as Hindu, Muslim, Christian and Banjaran women of Bihar, India. Different patterns of life and cultural variations exist among Muslims, Hindus, Christians, and Banjarans. For example, Muslim wash their genital parts after urination and maintain genital hygiene, whereas Banjaran tribes, Christians, and Hindu communities do not maintain hygiene. Thus, the present study was undertaken to evaluate high-risk HPV (HR-HPV) infection among healthy women. We access to genuine reason for the cause of HPV transmission in women. METHODS Ethical clearance was obtained from MCS and RC Patna, India. A total 154 urine samples have been used for the detection of HR-HPV through a real-time PCR technique. The DNA extraction was done from collected non-invasive urine samples. The estimation and purification of DNA purity was performed by QuantiFluor® dsDNA system and detected HPV-16 and HPV-18. RESULTS Overall, the prevalence of HR-HPV infection was detected to be 12.34% (19/154) whereas HPV-16 was found to be 9.9% (14/154) and HPV-18 was found to be 3.25% (5/154) in women. The lowest (2%; 1/50) prevalence of HR-HPV was observed in the Muslim community, while higher (25%, 16%, and 14.71%) prevalence was found in the Banjaran, Christian, and Hindu communities, respectively. CONCLUSION Our study indicates that personal hygiene possibly reduces HPV infection in women and the evidence suggests that male circumcision has a protective role of HPV infection in Muslim community. Therefore, personal hygiene and circumcision may reduce the risk of HPV acquisition and transmission as well as cervical cancer development in women.

Abstract
It is crucial to understand the natural history of genital human papillomavirus (HPV) infection in men to prevent the increasing male HPV-related disease burden. We evaluated the associations between HPV infection and circumcision, smoking, and alcohol use after accounting for sexual behavior. The study included 2331 male personnel from Danish barracks. Penile swabs were tested for HPV DNA with a polymerase chain reaction assay, INNO-LiPA. All men completed a self-administered questionnaire providing data on potential risk factors for HPV such as lifestyle and sexual habits. Using multivariable logistic regression, associations between potential risk factors and HPV infection were estimated and expressed as odds ratios (ORs) with 95% confidence intervals (CI). Current cigarette smoking was associated with increased odds of HPV detection (OR = 1.2; 95% CI: 1.0-1.4), but we found no association with alcohol use in the analysis adjusted for sexual behavior. Circumcision reduced the odds of a prevalent HPV infection (OR = 0.7; 95% CI: 0.5-1.0) although not statistically significantly. Strong associations with lifetime and recent number of female sex partners were observed, but in contrast to uncircumcised men, increasing number of sex partners was not associated with higher HPV prevalence in circumcised men. In conclusion, smoking was associated with increased odds of penile HPV in men from the general population in Denmark, whereas circumcision seemed to reduce the risk. Moreover, our results indicated that there might be differences in the viral susceptibility between circumcised and uncircumcised men.

Abstract
Although a growing body of literature has explored the association between religion and the prevalence of sexually transmissible infections (STIs), the focus has mainly been on HIV/AIDS and developing countries. Using data from the British National Surveys of Sexual Attitudes and Lifestyles (Natsal), we examine the direct association between religion and the prevalence of STIs including individual perception of exposure and risk of STIs. We focus on the importance of religion to respondents, religious affiliation as well as frequency of attendance to religious meetings. Our analyses suggest that being religious and frequently attending religious meetings are associated with lower odds of being diagnosed with STIs as well as lower self-assessed risk of getting HIV/AIDS. This seems particularly true for adherents of Christianity and more specifically, those of the Catholic denomination.

Abstract
INTRODUCTION Human papillomavirus infection (HPV) is one of the most common sexually transmitted infections and can cause penile and anal cancer in men, and invasive cervical cancer in women. OBJECTIVE To evaulate the colonization of 32 HPV subtypes in the foreskin of boys. STUDY DESIGN A prospective analysis was made of the data of 62 healthy boys who had undergone standard circumcision. Deoxyribonucleic acid (DNA) was isolated from the foreskin tissues, and the integrity of DNA was tested. The DNA of each patient was further assessed with real-time polymerase chain reaction (PCR) and the presence of 32 subtypes of HPV was explored. To confirm the results, melting curve analysis and agarose gel electrophoresis (AGE) were performed for all samples. Further analysis was made using LCD-array on six randomly selected samples to confirm the results together with negative and positive controls. RESULTS The mean age of the boys was 6.8 ± 2 years at the time of surgery. All positive controls and samples were positive, all negative controls were negative in the first HPV amplification assay. All positive controls had typical melting curve peaks, whereas all sample amplifications had non-specific, atypical melting curves not fitting with those of the positive controls. Two bands of expected sizes (124 and 405 bp) were only observed in positive controls, but not in negative controls or samples on AGE. The same results were observed on the 6 randomly selected samples using LCD-array. Consequently, all the foreskin samples were evaluated as negative for the 32 HPV types investigated in the study. DISCUSSION Literature shows a high prevalence of genital HPV in newborns, in early infancy, late adolescence and adulthood. However there is a lack of data in literature on the prevalence in early and late childhood. The negative results of HPV colonization on the foreskin in the current study may be attributed to the conservative and mostly monogamous nature of most family structures in Turkey. CONCLUSION The results of the present study have shown that foreskin tissue is not a natural reservoir for HPV and subclinical HPV infection is not likely in the absence of suspected sexual contact.

Abstract
Objectives: Epidemiological reports of sexual life and human papilloma virus (HPV) infection among Japanese men are scarce, and the necessity of HPV vaccines for males is regarded as a controversial topic in Japan. The objective of this study is to determine the prevalence, genotype distribution, and risk factors against HPV infections targeted by bivalent (2v), quadrivalent (4v), and 9-valent (9v) HPV vaccines among Japanese male patients who visited our urological clinics. Material and Methods: The study population consisted of 798 males aged 20 to 95 years (mean ± standard deviation, 55.4 ± 19.5 years). We collected scraping samples from the glans penis using cotton swabs from all patients for genotyping of HPVs. We compared patients’ characteristics and detected HPV genotypes in order to determine the risk factors against HPV infections. Results: Of 798 participants, 198 participants (198/798; 24.8%) had at least one genotype of any HPV infection. The total number of detected HPV genotypes was 328. Of 328 genotypes, 30% (n = 99; 99/328) were 9v HPV genotypes. Most frequently detected types of high-risk HPV infection were type 52 (n = 40; 40/328; 12.2%). Number of lifetime sex partners (≥21) and present or history of sexually transmitted infections were found to be predictors of any HPV infection with adjusted odds ratios of 3.106 (95% confidence interval (CI), 1.593–6.509) and 1.894 (95% CI, 1.185–3.026), respectively. Age of sex initiation was a predictor of 2v and 4v HPV infections with adjusted odds ratios of 100 (95% CI, 1.013–25.673) and 2.676 (95% CI, 1.037–6.905), respectively. Number of lifetime sex partners (≥21) was a predictor of 9v HPVs with adjusted odds ratios of 2.397 (95% CI, 1.060–5.424). Conclusions: Approximately, a quarter of Japanese male patients who visited urological clinics were exposed to HPV. Moreover, from the perspective of our multivariate logistic regression analysis, some kinds of sexual behavior aggravate the risk of typical HPV genotypes infections.

Abstract
Becoming armed with an appropriate strategy to isolate the minimum number of human papillomaviruses (HPV), regardless of DNA extraction method, can be a huge step in preventing false negative; it has a significant effect on the management and control of HPV infection among women's population. This study was conducted in Qom province, considering the risk factors associated with HPV. It was able to analyze genetic evolution in its genotypes and evaluated the limit of detection by a new diagnostic approach. Totally, 486 Pap smear samples were tested; then, the HPV DNA was developed by a semi-nested quantification PCR. Positive samples were sequenced and submitted to the GenBank (MG825048-MG825061). After alignment, phylogenetic and polymorphism analyses were performed on the sequenced samples with a number of GenBank sequences. The overall HPV prevalence among all women in Qom was 11.7%. HPV6 (43.24%) and HPV16 (6.75%) were the most frequent LR and HR genotypes, respectively. Although the Tajima's D of all genotypes was positive, it was negative individually. The position of genotypes 6, 11, and 73 was controversial on phylogenetic trees. Limit of detection (LOD) was obtained as about 10-100 copies per reaction in various genotypes of HPV by semi-nested qPCR. The nature of HPV could be preserved during natural selection. This research, through innovative usage of the primers, could detect different genotypes of the HPV, and inform the women society of the probable risk through its prevalence determination.

Abstract
OBJECTIVE Describe the natural history of anal HPV among men. MATERIALS AND METHODS Prospective study among men 18-70 years (n=665), from Cuernavaca, Mexico who completed questionnaires and provided specimens (HPV genotyped) at enrollment and 1+ follow-up visit. HPV prevalence and incidence were estimated. Prevalence ratios were calculated with Poisson regression using robust variance estimation. Person-time for incident HPV infection was estimated using number of events modeled as Poisson variable for total person-months. RESULTS Anal infection prevalence: any HPV type=15%, high-risk=8.4%, HPV16=1.4%, tetravalent vaccine types (4vHPV)=4.4%, nonavalent vaccine types (9vHPV)=6.3%. Factors associated with prevalence: 50+ lifetime female sex partners (adjusted prevalence ratio, a PR=3.25, 95% CI:1.12- 9.47), 10+ lifetime male sex partners (aPR=3.06, 95%CI:1.4- 6.68), and 1+ recent male anal sex partners (aPR=2.28, 95%CI:1.15-4.5). Anal incidence rate: high-risk HPV=7.8/1000 person-months (95%CI:6.0-10.1), HPV16=1.8/1000 personmonths (95%CI:1.1-2.9),4vHPV=3.4/1000 person-months (95%CI:2.3-4.9) and 9vHPV=5.5/1000 person-months (95%CI:4.1-7.5). CONCLUSIONS Implementation of universal HPV vaccination programs, including men, is a public health priority.

Prevalence of human papillomavirus and subtype distribution in male partners of women with cervical intraepithelial neoplasia (CIN): a systematic review. BMC Infect Dis 2019; 19:192. [PMID: 30808285 PMCID: PMC6390310 DOI: 10.1186/s12879-019-3805-x] [Citation(s) in RCA: 11] [Impact Index Per Article: 2.2] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/21/2018] [Accepted: 02/11/2019] [Indexed: 02/02/2023] Open
Abstract
Background Human Papillomavirus (HPV) infection is estimated to be the most common sexually transmitted infection. The present systematic review summarizes data regarding the prevalence of HPV and the distribution of subtypes in heterosexual male partners of women, who were diagnosed with any grade of cervical intraepithelial neoplasia (CIN). Methods We conducted a systematic review of the literature by Medline and Google Scholar databases using the terms “Human Papillomavirus” or “HPV” plus “men” or “male partners” or “women with CIN”. We included original published English-language articles published from 1/1/2000 until 1/1/2018 that had screened male partners of women with CIN using HPV DNA testing. We excluded studies that they overlapped with other included studies or were unrelated to the study subject. Results We included a total of 12 publications, which reported the prevalence of HPV in free-clinical signs male partners of women with CIN. The largest proportion of the studies were from South America (seven studies), and the rest from Europe. The mean age of participants was 35.18 + − 3.47 years. HPV prevalence ranged from 12.9 to 86%; the total HPV prevalence among the studies was 49.1%, while ten out twelve studies (83.3%) demonstrated prevalence > 20%. Between the studies, the distribution of HPV subtypes varied on the basis of the method used, on the population and on the geographic region. A great variety of subtypes were detected, including 6, 11, 16, 18, 31, 33, 40, 42, 45, 51, 52, 53, 54, 56, 57, 58, 59, 61, 62, 66, 68, 81 and 83. In six studies the HPV 16 was the most frequent, while in two others the HPV 6 and HPV 83. Conclusions Until now, there are not precise screening or surveillance guidelines for the management of partners of women with CIN. This population is frequently colonized by various HPV subtypes and therefore need to be screened in an effort to reduce the infection in both sexes. The screening test could include detection/identification of HPV subtypes by a molecular assay, followed by peniscopy only in the positive cases.

Does Male Circumcision Reduce Women's Risk of Sexually Transmitted Infections, Cervical Cancer, and Associated Conditions? Front Public Health 2019; 7:4.

Abstract
Background: Male circumcision (MC) is proven to substantially reduce men's risk of a number of sexually transmitted infections (STIs). We conducted a detailed systematic review of the scientific literature to determine the relationship between MC and risk of STIs and associated conditions in women. Methods: Database searches by "circumcision women" and "circumcision female" identified 68 relevant articles for inclusion. Examination of bibliographies of these yielded 14 further publications. Each was rated for quality using a conventional rating system. Results: Evaluation of the data from the studies retrieved showed that MC is associated with a reduced risk in women of being infected by oncogenic human papillomavirus (HPV) genotypes and of contracting cervical cancer. Data from randomized controlled trials and other studies has confirmed that partner MC reduces women's risk not only of oncogenic HPV, but as well Trichomonas vaginalis, bacterial vaginosis and possibly genital ulcer disease. For herpes simplex virus type 2, Chlamydia trachomatis, Treponema pallidum, human immunodeficiency virus and candidiasis, the evidence is mixed. Male partner MC did not reduce risk of gonorrhea, Mycoplasma genitalium, dysuria or vaginal discharge in women. Conclusion: MC reduces risk of oncogenic HPV genotypes, cervical cancer, T. vaginalis, bacterial vaginosis and possibly genital ulcer disease in women. The reduction in risk of these STIs and cervical cancer adds to the data supporting global efforts to deploy MC as a health-promoting and life-saving public health measure and supplements other STI prevention strategies.

[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
BACKGROUND Human papillomavirus (HPV)-induced lesions rarely develop in the urethral meatus (UM); however, their eradication can be problematic. METHODS A total of 22 patients with anogenital warts (AGWs) in the UM region and 22 patients with AGWs located at other anatomical sites were included in this cross-sectional study. The presence of human papillomavirus (HPV) types in biopsy samples was determined using the HPV Easy typing kit (GenID GmbH, Germany). RESULTS Although the patients in the AGW group with involvement of the UM had a higher incidence of reported multiple sexual partners (63.6% vs. 40.9%), larger meatus size (81.8% vs. 36.4%), and more frequent anal (36.4% vs. 18.2%) or unprotected sexual contact (68.2% vs. 36.4%) than those in the AGW group without UM involvement, only the duration of lesions (p = 0.04) and meatus size (p = 0.004) were significantly different in both groups. Low-risk HPV types were found in 75.0% and 69.2% of patients in the AGW groups with and without UM involvement, respectively. CONCLUSION We found that a larger UM size was more prone to the development of meatus AGWs; however, being married, delaying sexual debut, and avoidance of multiple sexual partners seemed to be associated with a decreased risk of development of AGWs, especially within the UM region.

Abstract
Context.—
The prevalence of human papillomavirus (HPV) infection varies worldwide. The high-risk viruses are usually associated with cancers of the cervix, vagina, and vulva in women, cancer of the penis in men, and cancers of the anus, tonsils, oropharynx, and base of the tongue in both sexes.
Objectives.—
To review literature about the challenges and burden associated with HPV infection in low-resource (ie, developing) countries, focusing on sub-Saharan Africa. To review the prevention, incidence, prevalence, morbidity, and mortality of HPV infections in sub-Saharan Africa. To review the therapy and management of HPV infections in low-resource countries in comparison to developed countries.
Data Sources.—
Peer-reviewed literature and experience of some of the authors.
Conclusions.—
Sub-Saharan Africa has high HPV infection prevalence rates, with predominance of high-risk subtypes 16, 18, and 45. The difficulty of access to health care has led to higher morbidity and mortality related to HPV-related cancers. Improvement in screening programs will help in monitoring the spread of HPV infections. Survival studies can be more informative if reliable cancer registries are improved. HPV vaccination is not yet widely available and this may be the key to curtailing the spread of HPV infections in resource-poor countries.

Abstract
BACKGROUND We undertook the current study on cervical Human Papillomavirus (HPV) prevalence along with cytology in women visiting the Gynecology Out-patient Department of a hospital for common gynecological ailments, subsequent to our earlier population-based study on HPV prevalence from India. METHODS We analyzed data on cervical-cytology (Pap smears) and PCR-based molecular detection of HPV infection along with socio-demographic variables (N = 696). RESULTS We identified 36.84% HPV-positive women amongst whom, HPV16 and 18 together predominated (79.37%) over other HPV types (20.63%). Contrarily, only 6.4% women revealed abnormal cytological lesions, of which, 46.51% were HPV-positive and 95% of such women harbored HPV16/18, while 5% harbored other HPV types. Individuals with normal cytology portrayed 36.09% HPV infections, of which, 77.97% were HPV16/18-positive and 22.03% harbored other HPV types. Overall HPV prevalence decreased significantly (ptrend = 0.047) with increase in age, but HPV16/18 infections were significantly over-represented compared to the other HPV types across all age-groups. Specifically, HPV16 prevalence increased (p trend < 0.01) with increase in severity of cervical lesions. HPV16 prevalence did not differ between the Hindus and Muslims but HPV18 was significantly higher among the cytologically normal Muslim women (24.14%, p = 0.02), compared to the Hindus (11.91%), specifically among those ≥ 30 years of age. There was a significant (p < 0.05) overrepresentation of HPV16 prevalence among women who were users of oral contraceptive-pills, irrespective of cytology. CONCLUSIONS Our study highlights the need for HPV16/18-based screening of cervical cancers in India considering the immense socio-cultural and genetic diversity at the population level.

Abstract
OBJECTIVES The incidence of recurrent genital warts is not well characterized; this is especially true in a post-human papillomavirus (HPV) vaccination era. The objectives of this study were to assess the incidence of subsequent HPV-related external genital warts (EGW) episodes in high-risk male and female adults, as well as ascertain patient profile and disease characteristics, in a real-world Canadian sexual health clinical setting. METHODS Retrospective chart review study conducted at Clinique médicale l'Actuel, a sexual health clinic in Montréal, Québec, Canada. Eligible patients were 18 to 45 years of age with a first diagnosis of EGW associated with a HPV infection between July 1, 2006, and June 30, 2012. RESULTS A total of 400 first-episode EGW cases were identified. Up to 6 subsequent episodes were documented, with 194 (48.5%) patients reporting at least 1 subsequent EGW episode. Median time to first subsequent EGW episode was 3.97 years, and the incidence density rate for all subsequent episodes was 0.18/100 patient-years. Over 90% of patients reported clearance of the first subsequent episode, with median time to clearance of 0.30 years. Regardless of subsequent episode number, greater than 95% of patients received treatment, primarily cryotherapy, with high-risk sexual behavior reducing as number of episodes increased. CONCLUSIONS Overall, a high rate of subsequent EGW episodes was observed in this high-risk population, despite high treatment rates and improvement in high-risk sexual behavior. These data, assessed in a prevaccination Québec health care system, may be compared with future EGW rates to assess the impact of a governmentally-funded HPV vaccination program.

Abstract
BACKGROUND The incidence of penile cancer in Indian men is high. Little is known about genital human papillomavirus (HPV) infection in Indian HIV-seropositive men who have sex with men (MSM), a population that may be at particularly high risk for genital HPV infection and, potentially, penile cancer. In this study, we assessed the prevalence and risk factors for genital HPV infection in this population. DESIGN AND METHODS Three hundred HIV-seropositive MSM were recruited from 2 clinical sites in India. They were tested for genital HPV infection using L1 HPV DNA polymerase chain reaction with probes specific for 29 types and a mixture of 10 additional types. Participants received an interviewer-administered questionnaire that included questions on demographics and behaviors. RESULTS Human papillomavirus data were available from 299 participants. The prevalence of any HPV type in the penis and scrotum was 55% and 54%, respectively. Human papillomavirus type 35 was the most common oncogenic HPV type followed by HPV-16. In multivariate analysis, being the insertive partner with 100+ male partners increased the odds of any penile HPV infection compared with not being insertive with any partners (odds ratio, 2.5; 95% confidence interval, 1.3-5.1). Circumcision was protective against penile HPV infection (odds ratio, 0.39; 95% confidence interval, 0.19-0.76). CONCLUSIONS The prevalence of penile and scrotal HPV infection was high among Indian HIV-seropositive MSM. The most common oncogenic HPV type in this population, HPV-35, is not included in any currently available HPV vaccines. Insertive anal sex with men and lack of circumcision were the primary risk factors for penile HPV infection in this population.

Abstract
The high prevalence of human papillomavirus (HPV), the most common sexually transmitted infection, arises from the coexistence of over 200 genetically distinct types. Accurately predicting the impact of vaccines that target multiple types requires understanding the factors that determine HPV diversity. The diversity of many pathogens is driven by type-specific or "homologous" immunity, which promotes the spread of variants to which hosts have little immunity. To test for homologous immunity and to identify mechanisms determining HPV transmission, we fitted nonlinear mechanistic models to longitudinal data on genital infections in unvaccinated men. Our results provide no evidence for homologous immunity, instead showing that infection with one HPV type strongly increases the risk of infection with that type for years afterward. For HPV16, the type responsible for most HPV-related cancers, an initial infection increases the 1-year probability of reinfection by 20-fold, and the probability of reinfection remains 14-fold higher 2 years later. This increased risk occurs in both sexually active and celibate men, suggesting that it arises from autoinoculation, episodic reactivation of latent virus, or both. Overall, our results suggest that high HPV prevalence and diversity can be explained by a combination of a lack of homologous immunity, frequent reinfections, weak competition between types, and variation in type fitness between host subpopulations. Because of the high risk of reinfection, vaccinating boys who have not yet been exposed may be crucial to reduce prevalence, but our results suggest that there may also be large benefits to vaccinating previously infected individuals.

Abstract
HPV is the sexually transmitted agent most common among young people, like college students. The aim of study was to associate sexual behavior characteristics of women with HPV, detected in genital samples taken before the introduction of the HPV vaccine. Female students during 2001-2005 donated genital samples and the samples were re-analyzed in 2013 for HPV genotyping by RT-PCR. The frozen storage of the students' genital samples allowed the detection of HPV DNA and its genotyping after years of sample collection. HPV prevalence was 22%, HPV16 3.9%, and HPV18 1.1%. Age, multiple sexual partners and the partner's age at first sexual intercourse were significantly associated to HPV. Students with ≥ 3 sexual partners and who did not use condom had 12.8 higher odds of being HPV positive. These results made possible the analysis of HPV prevalence changes, before HPV vaccine introduction.

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
Data on cutaneous human papillomavirus (HPV) seroprevalence are primarily derived from skin cancer case-control studies. Few studies have reported the seroprevalence of cutaneous HPV among healthy men. This study investigated the seroprevalence of cutaneous HPV types and associated risk factors among men residing in Brazil, Mexico and the USA. Six hundred men were randomly selected from the HPV Infection in Men study. Archived serum specimens were tested for antibodies against 14 cutaneous HPV genotypes, β-HPV types (5/8/12/14/17/22/23/24/38/48), α-HPV 27, γ-HPV 4, µ-HPV1 and ν-HPV 41 using a glutathione S-transferase L1-based multiplex serology assay. Risk factor data were collected by a questionnaire. Binomial proportions were used to estimate seroprevalence, and logistic regression to examine factors associated with seropositivity. Overall, 65.4 % of men were seropositive to ≥1 of the 14 cutaneous HPV types, and 39.0 % were positive for ≥1 β-HPV types. Seroprevalence was 8.9, 30.9, 28.6 and 9.4 % for α-HPV 27, γ-HPV 4, µ-HPV 1 and ν-HPV 41, respectively. In multivariate analyses, seropositivity for any cutaneous HPV type was associated with higher education [adjusted odds ratio (AOR) 1.75; 95 % confidence interval (CI) 1.08-2.83], and seropositivity of any β-HPV type was significantly associated with increasing age (AOR 1.72; 95 % CI 1.12-2.63, for men aged 31-44 years vs men aged 18-30 years). Other factors associated with various type-specific cutaneous HPV seropositivity included country, circumcision and lifetime number of male sexual partners. These data indicate that exposure to cutaneous HPV is common. Future studies are needed to assess the role of cutaneous HPV in diseases.

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 It is crucial to understand the epidemiology and natural history of human papillomavirus (HPV) infection in both men and women, to prevent the increasing HPV-related disease burden in men. Data on HPV prevalence among men in the general population are limited. In this cross-sectional population-based study, we aimed to estimate genital HPV infection prevalence in Danish men using 2 different test methods. METHODS Penile swab samples from 2460 male employees and conscripts at military barracks in Denmark were tested for HPV DNA with the hybrid capture 2 (HC2) method, and a polymerase chain reaction (PCR) assay, Inno-LiPA. The overall and age- and type-specific prevalence of HPV infection with 95% confidence intervals (CIs) were estimated, and the correlation between the 2 assays was assessed. RESULTS The overall HPV prevalence was 22.2% (95% CI, 20.6-23.9) in the HC2 test and 41.8% (95% CI, 39.9-43.8) with PCR. Of the PCR-positive samples, 50.9% were negative in the HC2 test. Of 183 PCR-positive samples that could not be genotyped (HPVX), 88.0% (95% CI, 83.2-92.7) were HC2 negative. The most prevalent types were HPV-51, HPV-16, HPV-66, HPV-53, and HPV-6. The prevalence of high-risk and low-risk HPV peaked among men aged 20 to 29 years, whereas the HPVX prevalence increased with age. CONCLUSIONS Human papillomavirus is highly prevalent in the general male population of Denmark, with HPV-16 and HPV-51 being the most prevalent. Polymerase chain reaction detects twice as many positive samples as HC2 but includes HPVX, possibly representing cutaneous HPV types found on normal genital skin.

Abstract
BACKGROUND Male circumcision (MC) status and genital infection risk are interlinked and MC is now part of HIV prevention programs worldwide. Current MC prevalence is not known for all countries globally. Our aim was to provide estimates for country-specific and global MC prevalence. METHODS MC prevalence data were obtained by searches in PubMed, Demographic and Health Surveys, AIDS Indicator Surveys, and Behavioural Surveillance Surveys. Male age was ≥15 years in most surveys. Where no data were available, the population proportion whose religious faith or culture requires MC was used. The total number of circumcised males in each country and territory was calculated using figures for total males from (i) 2015 US Central Intelligence Agency (CIA) data for sex ratio and total population in all 237 countries and territories globally and (ii) 2015 United Nations (UN) figures for males aged 15-64 years. RESULTS The estimated percentage of circumcised males in each country and territory varies considerably. Based on (i) and (ii) above, global MC prevalence was 38.7 % (95 % confidence interval [CI]: 33.4, 43.9) and 36.7 % (95 % CI: 31.4, 42.0). Approximately half of circumcisions were for religious and cultural reasons. For countries lacking data we assumed 99.9 % of Muslims and Jews were circumcised. If actual prevalence in religious groups was lower, then MC prevalence in those countries would be lower. On the other hand, we assumed a minimum prevalence of 0.1 % related to MC for medical reasons. This may be too low, thereby underestimating MC prevalence in some countries. CONCLUSIONS The present study provides the most accurate estimate to date of MC prevalence in each country and territory in the world. We estimate that 37-39 % of men globally are circumcised. Considering the health benefits of MC, these data may help guide efforts aimed at the use of voluntary, safe medical MC in disease prevention programs in various countries.

Abstract
Background In the literature, data on the prevalence of human papillomavirus (HPV) infection in men vary significantly and the exact distribution of specific genotypes is still unclear. As infections usually occur without symptoms, men might only attend their hospital clinic when they have a specific concern, being in most cases genital warts (condylomas), which are often caused by low-risk HPV genotypes. The aim of this study was to assess HPV genotype distribution and prevalence among men attending hospital for HPV-associated conditions and to evaluate infection-associated factors. Methods Samples from men with clinical manifestations of HPV-related infections seen during 2007–2012 at the Clinical Microbiology and Infectious Control Department at Basurto University Hospital were genotyped using Linear Array HPV Genotyping Test kit (Roche Molecular Diagnostics, Germany). Data on probable risk factors were collected and investigated for possible association. Results Of 184 anogenital samples, 138 (75 %) were tested as positive for HPV; 57 (41.3 %) single HPV infections and 81 (58.7 %) multiple infections. Only 45.6 % of HPV-positive samples presented low-risk genotypes 6 or 11, whereas 71/138 (51.4 %) had at least one oncogenic (high-risk) genotype. Oncogenic genotypes and multiple HPV infections were both associated with a higher number of lifetime sexual partners and their incidence appeared to increase with patient age. Conclusions Although it is accepted that HPV 6 and 11 genotypes are main causes of condylomas, our findings show a high incidence of multiple infections and high-risk genotypes in men with benign HPV manifestations. The fact that the condyloma is a skin lesion facilitates the entry of virus into cells and thus cancer progression; therefore, monitoring for HPV is important, especially in those patients with high-risk genotypes (regardless of whether they cause condyloma).

Abstract
OBJECTIVES We examined sexual-orientation disparities in frequent engagement in cancer-related risk indicators of tobacco, alcohol, diet and physical activity, ultraviolet radiation, and sexually transmitted infections (STIs). METHODS We used longitudinal data from the national Growing Up Today Study (1999-2010). Of the analytic sample (n = 9958), 1.8% were lesbian or gay (LG), 1.6% bisexual (BI), 12.1% mostly heterosexual (MH), and 84.5% completely heterosexual (CH). RESULTS More sexual minorities (LGs, BIs, and MHs) than CHs frequently engaged in multiple cancer-related risk behaviors (33%, 29%, 28%, and 19%, respectively). Sexual-minority young women, especially BI and MH, more frequently engaged over time in substance use and diet and physical activity risk than CH women. More young gay than CH men frequently engaged over time in vomiting for weight control (odds ratio [OR] = 3.2; 95% confidence interval [CI] = 1.1, 9.4), being physically inactive (OR = 1.7; 95% CI = 1.2, 2.4), and using tanning booths (OR = 4.7; 95% CI = 3.0, 7.4), and had a higher prevalence of ever having an STI (OR = 3.5; 95% CI = 2.0, 6.4). Individual analyses were generally comparable to the group-level analyses. CONCLUSIONS Young sexual minorities are at risk for cancer through frequent exposure to cancer-related risk behaviors over time. Long-term, longitudinal studies and surveillance data are essential and warranted to track frequent engagement in the risk behaviors and cancer-related morbidity and mortality.

Jundishapur J Microbiol 2015; 8:e21912. [PMID: 26862386 PMCID: PMC4741186 DOI: 10.5812/jjm.21912] [Citation(s) in RCA: 22] [Impact Index Per Article: 2.4] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/13/2014] [Revised: 10/12/2014] [Accepted: 10/31/2014] [Indexed: 12/04/2022] Open
Abstract
Background: Human papillomavirus (HPV) is the most common viral sexually-transmitted infection. Despite HPV infection is associated with several malignant disorders including penile and anal cancers, little is known about the epidemiology of HPV infection in males, particularly in developing countries. Objectives: The aim of this study was to determine the prevalence of HPV infection and its genotype distribution among Iranian males. Patients and Methods: Between March 2009 and April 2014, a total number of 483 males, referred to Iran University of Medical Sciences-affiliated sexually transmitted infections (STI) clinics, were enrolled in this study. Following DNA extraction, HPV detection and genotyping were performed using INNO-LiPA HPV Genotyping Extra assay. To analyze the association of HPV infection and age, the logistic regression was employed. Results: No statistical association between HPV infection and age was observed (P = 0.469). Furthermore, there was no statistically significant correlation between HR HPV infection and age (P = 0.330). Conclusions: In this investigation, the prevalence of HPV infection was relatively substantial. Totally, 17 different HPV genotypes were detected and the most frequently detected genotypes were HPV6, HPV11, HPV16, HPV18 and HPV52, respectively. The data from this study is essential for planning future public health strategies including HPV vaccination programs.

Abstract
INTRODUCTION Circumcision is the most common surgical procedure in male children in the world and is performed because of cultural, religious or medical reasons. Traditionally, interrupted sutures are used to close the wound, but 2-Octyl cyanoacrylate (2-OCA) tissue glue can be used as an alternative method to close the circumcision wound. OBJECTIVES To compare the use of 2-OCA with absorbable sutures in circumcision wound closure in prepubescent patients in terms of operative time, complication rate, postoperative pain and cosmetic results. STUDY DESIGN We retrospectively evaluated 662 circumcision procedures using sutures and 609 procedures using 2-OCA for wound closure in prepubescent boys. All circumcision procedures were performed by 2 surgeons in a single centre. Operative time was collected from the hospital surgical software system. 62% of the patients in the suture group and 59% of the patients in the 2-OCA group presented for a postoperative check-up 6 weeks after the circumcision. Data regarding postoperative pain, need for analgesia, cosmetic satisfaction and the ease of wound care were collected through questionnaires completed by 25% of the boy's parents in the suture group and 53% of the parents in the 2-OCA group. RESULTS Mean operative time was significantly shorter in the 2-OCA group (13 min) than in the suture group (17 min). Complications were comparable and mostly minor. Reintervention was only required in 3 cases. According to the parents, the degree of postoperative pain and the postoperative need for analgesics was significantly lower in the 2-OCA group. Wounds closed with 2-OCA were easier to care for. The cosmetic results after 1 day, after 1 week and after 1 month in the 2-OCA group were significantly superior than in the suture group, according to the parents' evaluation. DISCUSSION The use of 2-OCA in circumcision wound closure has been reported before. Previous studies with mainly limited patient numbers report less pain, shorter procedure times and a higher surgeon satisfaction in terms of cosmetic results. This study is the largest study comparing the use of 2-OCA and interrupted sutures in circumcision wound closure. The retrospective character of the study, the lack of a validated questionnaire tool for the cosmetic evaluation and the use of the parent's evaluation are the limitations of this study. CONCLUSION The use of 2-OCA in circumcision wound closure results in a shorter operative time, in less postoperative pain, in easy postoperative wound care and in excellent cosmesis when compared to interrupted absorbable sutures. 2-OCA is our current technique of choice in circumcision wound closure.

Abstract
BACKGROUND Homosexual men infected with human immunodeficiency virus (HIV) are at increased risk of developing anal cancer. The aim of this study was to assess the clinical sensitivity of anal cytology analysis and oncogenic human papillomavirus (HPV) detection for predicting histological anal intraepithelial neoplasia. METHODS Between March 2011 and December 2013, we enrolled 196 HIV-positive men in Taoyuan General Hospital, Taiwan. We analyzed the results of thin-preparation anal Pap smears, HPV genotyping, and histology of anoscopic biopsy samples. RESULTS The mean age (±standard deviation) was 31.43 (±8.74) years. The proportion (95 % confidence interval) with abnormal thin-preparation anal cytology was 36.2 % (29.8-43.2 %): 16.8 % (12.2-22.7 %) atypical squamous cells of undetermined significance, 14.8 % (10.5-20.4 %) low-grade squamous intraepithelial lesions, and 4.6 % (2.4-8.5 %) high-grade squamous intraepithelial lesions. At least one HPV genotype was detected in 90.8 % of subjects, and the mean number of HPV infection types was 4.41 (±3.24).The frequency of histological high-grade anal intraepithelial lesions was 7.14 % (95 % confidence interval 4.3-11.6 %). Anal cytology yielding atypical squamous cells of undetermined significance or higher grades resulted in a sensitivity of 64.3 %, specificity of 65.9 %, positive predictive value of 12.7 %, and negative predictive value of 96 %. Using both oncogenic HPV and cytology did not provide better performance. CONCLUSIONS Anal cytology yielding atypical squamous cells of undetermined significance or higher grades could detect two-thirds of high-grade anal intraepithelial neoplasias in HIV-infected men and should be promoted for anal cancer prevention.

Abstract
INTRODUCTION Human papillomavirus (HPV) is the commonest sexually transmitted infection worldwide and causes substantial morbidity in both sexes. Most European countries offer HPV vaccination for girls, but vaccine recommendations for boys are warranted. AIMS The aims of this study were to investigate the prevalence of genital HPV, identify parameters that affect the prevalence, and describe the type-specific prevalence among men in Europe. METHODS A systematic review and meta-analysis of the published literature in PubMed and Embase. MAIN OUTCOME MEASURES Genital HPV prevalence and factors influencing prevalence in general and high-risk male populations in Europe. RESULTS We included 31 articles that gave the prevalence of genital HPV DNA among men in northern, southern and western Europe; no studies from eastern Europe were identified. The pooled HPV prevalence among 1,863 men representing the general population (nine studies) was 12.4%, with large heterogeneity between studies (I(2) = 96.3%, P < 0.0001). The pooled HPV prevalence among 6,428 men in the high-risk population (22 studies) was 30.9%, also with substantial heterogeneity (I(2) = 95.6%, P < 0.0001). In unadjusted meta-regression analysis, the HPV prevalence in the general population was significantly higher in studies published after 2000 (28.5%) than in earlier studies (8.8%) (P = 0.0179). In the meta-regression analysis adjusted by publication year, the heterogeneity in the two population groups could not be explained by geographical region, anatomical sampling site, or HPV detection method. HPV16 was the most prevalent high-risk type in both populations. CONCLUSIONS HPV prevalence differs in male general and high-risk populations, but HPV16 and HPV18 are among the most common HPV types detected in both groups. Our findings contribute knowledge that may be useful as a baseline measure before the introduction of HPV vaccination for boys in Europe, and add to understanding of the epidemiology of HPV infection in men.

Abstract
PURPOSE The worldwide prevalence of human papillomavirus (HPV) infection is estimated at 9-13 %. Persistent infection can lead to the development of malignant and nonmalignant diseases. Low-risk HPV types are mostly associated with benign lesions such as anogenital warts. In the present systematic review, we examined the impact of smoking on HPV infection and the development of anogenital warts, respectively. METHODS A systematic literature search was performed using MEDLINE database for peer-reviewed articles published from January 01, 1985 to November 30, 2013. Pooled rates of HPV prevalence were compared using the χ (2) test. RESULTS In both genders, smoking is associated with higher incidence and prevalence rates for HPV infection, whereas the latter responds to a dose-effect relationship. The overall HPV prevalence for smoking patients was 48.2 versus 37. 5 % for nonsmoking patients (p < 0.001) (odds ratio (OR) = 1.5, 95 % confidence interval (CI) 1.4-1.7). Smoking does also increase persistence rates for high-risk HPV infection, while this correlation is debatable for low-risk HPV. The incidence and recurrence rates of anogenital warts are significantly increased in smokers. CONCLUSIONS Most current data demonstrate an association between smoking, increased anogenital HPV infection, and development of anogenital warts. These data add to the long list of reasons for making smoking cessation a keystone of patient health.

Abstract
OBJECTIVES We examined the role of adolescent peer violence victimization (PVV) in sexual orientation disparities in cancer-related tobacco, alcohol, and sexual risk behaviors. METHODS We pooled data from the 2005 and 2007 Youth Risk Behavior Surveys. We classified youths with any same-sex sexual attraction, partners, or identity as sexual minority and the remainder as heterosexual. We had 4 indicators of tobacco and alcohol use and 4 of sexual risk and 2 PVV factors: victimization at school and carrying weapons. We stratified associations by gender and race/ethnicity. RESULTS PVV was related to disparities in cancer-related risk behaviors of substance use and sexual risk, with odds ratios (ORs) of 1.3 (95% confidence interval [CI] = 1.03, 1.6) to 11.3 (95% CI = 6.2, 20.8), and to being a sexual minority, with ORs of 1.4 (95% CI = 1.1, 1.9) to 5.6 (95% CI = 3.5, 8.9). PVV mediated sexual orientation disparities in substance use and sexual risk behaviors. Findings were pronounced for adolescent girls and Asian/Pacific Islanders. CONCLUSIONS Interventions are needed to reduce PVV in schools as a way to reduce sexual orientation disparities in cancer risk across the life span.

Abstract
BACKGROUND Baseline genotype-specific human papillomavirus (HPV) prevalence rates and associated risk factors per gender enable future assessment of the impact of vaccination on HPV dynamics. METHODS Before the start of national HPV vaccination for girls, data were collected cross-sectionally in nationwide Dutch sexually transmitted infections (STI) clinics among heterosexual males (n = 430) and females (n = 1136) aged 16 to 24 years. Self-collected vaginal or penile swabs were analyzed by a sensitive polymerase chain reaction (SPF10) and genotyped with line probe assay. Logistic regression was applied to estimate determinants of HPV prevalent infections. RESULTS HPV prevalence was 54% among males and 72% among females. High-risk (HR) HPV was present in males and females, 40% and 58%, respectively. Independent risk factors for HR-HPV infection were female gender, number of lifetime sex partners and a history of chlamydia or gonorrhea. In addition, not having a casual partner and consistent condom use were protective factors in women, but not in men. For low-risk (LR) HPV, the odds were smaller. Multiple HR-HPV and sexual risk behavior showed a stronger association compared with a single HR-HPV infection. CONCLUSIONS Prevalence of HR-HPV is high in both genders. Infection with multiple HR-HPV types was more associated with high-risk sexual behavior than infection with LR-HPV types or a single HR-HPV type.

Abstract
BACKGROUND In this analysis, we examine the incidence and clearance of external genital human papillomavirus (HPV) infection among heterosexual males aged 16-24 years. METHODS A total of 1732 males aged 16-24 years old in the placebo arm of a quadrivalent HPV vaccine trial were included in this analysis. Participants were enrolled from 18 countries in Africa, the Asia-Pacific region, Europe, Latin America, and North America. Subjects underwent anogenital examinations and sampling of the penis, scrotum, and perineal/perianal regions. RESULTS The incidence rate of any HPV DNA genotype 6, 11, 16, and/or 18 detection was 9.0 cases per 100 person-years. Rates of HPV DNA detection were highest in men from Africa. Median time to clearance of HPV genotypes 6, 11, 16, and 18 DNA was 6.1, 6.1, 7.7, and 6.2 months, respectively. Median time to clearance of persistently detected HPV 6, 11, 16, and 18 DNA was 6.7, 3.2, 9.2, and 4.7 months, respectively. CONCLUSION The study results suggest that the acquisition of HPV 6, 11, 16, and/or 18 in males is common and that many of these so-called infections are subsequently cleared, similar to findings for women. Nevertheless, given the high rate of HPV detection among young men, HPV vaccination of males may reduce infection in men and reduce the overall burden of HPV-associated disease in the community.

Abstract
Purpose Recent studies in Puerto Rico have reported an increasing incidence of anal cancer in Puerto Rican men. The objective of this study was to determine the prevalence, genotype distribution and risk factors associated with anal HPV infection among men attending an STI clinic in Puerto Rico. Methods We conducted a cross-sectional study among 205 men 18 years and older. A comprehensive survey was administered that included a demographic and a behavioral assessment. Separate logistic regression models were performed to determine factors associated with any, high-risk (HR), and multiple anal HPV infection. Results The mean age of the study sample was 38.0±13.5 years. The most common HR types were 58, 51 and 31. Overall, HR anal HPV infection was found in 53.5% of the participants. Multiple HPV types in the anal canal were found in 47.6% of the sample. A third (29.8%) of participants reported being men who had sex with men (MSM). MSM had a significantly higher prevalence of any, HR and multiple HPV infection (p-value<0.05). Separate multivariate logistic regression analyses showed that being MSM was associated with any (OR = 4.5; [95%CI: 1.9–10.7]), HR (OR = 3.4; [95%CI: 1.1–10.3) and multiple anal HPV infection (OR = 3.6; [95%CI: 1.5–9.1). HIV was marginally associated with multiple anal HPV infection in multivariate analysis (OR = 3.3; 95%CI = 1.0–11.0). Conclusions Anal HPV is common among sexually active men attending this STI clinic, with higher likelihood of anal HPV infection among MSM.

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.

OBJECTIVES We examined sexual orientation disparities in cancer-related risk behaviors among adolescents. METHODS We pooled data from the 2005 and 2007 Youth Risk Behavior Surveys. We classified youths with any same-sex orientation as sexual minority and the remainder as heterosexual. We compared the groups on risk behaviors and stratified by gender, age (< 15 years and > 14 years), and race/ethnicity. RESULTS Sexual minorities (7.6% of the sample) reported more risk behaviors than heterosexuals for all 12 behaviors (mean = 5.3 vs 3.8; P < .001) and for each risk behavior: odds ratios (ORs) ranged from 1.3 (95% confidence interval [CI] = 1.2, 1.4) to 4.0 (95% CI = 3.6, 4.7), except for a diet low in fruit and vegetables (OR = 0.7; 95% CI = 0.5, 0.8). We found sexual orientation disparities in analyses by gender, followed by age, and then race/ethnicity; they persisted in analyses by gender, age, and race/ethnicity, although findings were nuanced. CONCLUSIONS Data on cancer risk, morbidity, and mortality by sexual orientation are needed to track the potential but unknown burden of cancer among sexual minorities.

Abstract
BACKGROUND HIV-positive men who have sex with men (MSM) are at high risk of anal cancer compared with the general population. Human papillomavirus (HPV) infection, particularly HPV 16, is causally associated with anal cancer. However, the risk factors for anal HPV 16 infection are poorly understood. We determined the prevalence and risk factors for anal HPV 16 infection in a population of HIV-positive MSM, most of whom were being treated with antiretroviral therapy. DESIGN Cross-sectional data from the baseline visit of a 4-year prospective cohort study. METHODS Three hundred forty-eight HIV-positive MSM were recruited in San Francisco, and they received a detailed sexual behavior risk factor questionnaire. An anal swab was used to collect specimens for HPV type-specific DNA testing using L1 HPV DNA polymerase chain reaction. We used log-binomial multivariable models to determine the risk factors for anal HPV 16 infection. RESULTS Ninety-two percent of HIV-positive MSM had at least 1 anal HPV type, 80% had at least 1 oncogenic HPV type, and 42% had HPV 16. Non-Hispanic white race and higher level of education were associated with a decreased risk of HPV 16 infection. A higher number of total male partners was associated with HPV 16 (relative risk: 1.6, 95% confidence interval 1.1 to 2.4, P = 0.01) for 201-1000 partners compared with 1-200. Injection drug use was independently associated with anal HPV 16 infection (relative risk: 1.5, 95% confidence interval 1.2 to 1.9, P = 0.003). CONCLUSIONS The prevalence of anal HPV infection, including HPV 16, is high in HIV-positive MSM. HIV-positive MSM should be counseled about the risk associated with increased partners and injection drug use.

Abstract
Introduction Exploring different sampling sites and methods is of interest for studies of the epidemiology of HPV infections in the male. Expressed prostate secretions (EPS) are obtained during digital rectal examination (DRE), a daily routine urological diagnostic procedure, following massage of the prostate. Materials and Methods Urethral swabs and EPS samples were obtained from a consecutive sample of 752 men (mean age 32.4 years; median life-time sex partners 34) visiting urology outpatient clinics in St. Petersburg, Russia and tested for HPV DNA by general primer PCR, followed by genotyping using Luminex. Results Overall, 47.9% (360/752) of men were HPV-positive, with 42.0% (316/752) being positive for high-risk (HR-) HPV and 12.6% (95/752) for multiple HPV types. HPV-positivity in the EPS samples was 32.6% (27.7% HR-HPV) and in the urethral samples 25.9% (24.5% HR-HPV). 10.6% were HPV positive in both EPS and urethral samples. 6.4% had the same HPV-type in both EPS and urethral samples. 10.6% were HPV positive in both EPS and urethral samples. 6.4% had the same HPV-type in both EPS and urethral samples. The concordance between the urethral samples and EPS was 62.5% (470/752), with 80 cases double positive and 390 cases double negative in both sites. The sensitivity of urethral samples for overall HPV detection was 54.2% (195/360). Compared to analysis of urethral samples only, the analysis of EPS increased the HPV prevalence in this population with 26.2%. Conclusion EPS represent informative sampling material for the study of HPV epidemiology in the male.

Abstract
BACKGROUND Comparative studies of genital human papillomavirus (HPV) among men having sex with men (MSM), men having sex with women and men (MSWM), and men having sex with women (MSW) have not been conducted so far; however, such comparisons may be important for planning prevention strategies like vaccination. METHODS Men, aged 18 to 70 years, were enrolled in a study of genital HPV in São Paulo, Brazil; Cuernavaca, Mexico; and Tampa, FL. Men were classified as MSM (n = 170), MSWM (n = 214), and MSW (n = 3326) based on self-reported sexual behavior. Genotyping for HPV was conducted on cells from the penis and scrotum. Prevalence data were adjusted by country. Factors potentially associated with genital HPV were assessed using multivariable Poisson regression. RESULTS Genital HPV prevalence was typically higher among MSWM than among MSM or MSW for groups of HPV genotypes including nononcogenic types (51%, 36%, and 42%, respectively), and multiple types (37%, 24%, and 29%, respectively). Age and alcohol consumption in the past month were associated with oncogenic HPV among both MSM and MSWM; however, there were no statistically significant associations between sexual behaviors and genital HPV among MSM or MSWM. CONCLUSIONS Prevalence of genital HPV may be higher among MSWM than among MSW or MSM. Number of female sex partners was associated with genital HPV among MSW, but number of male anal sex partners was not associated with genital HPV among MSM and MSWM.

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 Human Papillomavirus (HPV) is a very resistant, ubiquitous virus that can survive in the environment without a host. The decision to analyse HPV-related diseases in males was due to the broad dissemination of the virus, and, above all, by the need to stress the importance of primary and secondary prevention measures (currently available for women exclusively). The objective of the Consensus Conference was to make evidence-based recommendations that were designed to facilitate the adoption of a standard approach in clinical practice in Italy. METHODS The Sponsoring Panel put a series of questions to the members of the Scientific Committee who prepared a summary of the currently available information, relevant for each question, after the review and grading of the existing scientific literature. The summaries were presented to a Jury, also called multidisciplinary Consensus Panel, who drafted a series of recommendations. RESULTS The prevalence of HPV in males ranges between 1.3-72.9%;. The prevalence curve in males is much higher than that in females and does not tend to decline with age. Women appear to have a higher probability of acquiring HPV genotypes associated with a high oncogenic risk, whereas in males the probability of acquiring low- or high-risk genotypes is similar. The HPV-related diseases that affect males are anogenital warts and cancers of the penis, anus and oropharynx. The quadrivalent vaccine against HPV has proved to be effective in preventing external genital lesions in males aged 16-26 years in 90.4%; (95%; CI: 69.2-98.1) of cases. It has also proved to be effective in preventing precancerous anal lesions in 77.5%; (95%; CI: 39.6-93.3) of cases in a per-protocol analysis and in 91.7%; (95%; CI: 44.6-99.8) of cases in a post-hoc analysis. Early ecological studies demonstrate reduction of genital warts in vaccinated females and some herd immunity in males when vaccine coverage is high, although males who have sex with males gained no benefit at all. Males with an immunodeficiency disease are at greater risk of developing disease. Infertility seems to be caused by HPV in some cases. Studies demonstrate vaccination to both genders can be more efficacious and social equity matters are to be taken into consideration. CONCLUSIONS The Jury made Recommendations based on the scientific evidence presented by the Scientific Committee. Accordingly, for prevention purposes and social fairness and equality, as both sexes are affected by the disease, the vaccination of 12-year-old males against HPV should be recommended in order to guaranty protection to everyone. Aspects related to healthcare policy and economic sustainability, are to be discussed by respective public system representatives. More campaigns to raise awareness through all institutional channels are needed, not only regarding anogenital warts, but for HPV-related diseases in general in males in accordance to new scientific evidences.

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 Genital Human papilloma virus (HPV) is one of the most commonly diagnosed Sexually Transmitted Infection (STIs) in men and women. Knowledge about HPV infection among men is limited. This study aims to determine correlates of adequate knowledge of HPV infection among men who attend an STI clinic in Puerto Rico. Methods A cross-sectional study of 206 men was conducted at an STI clinic in San Juan, PR. Adequate knowledge was defined as a score of at least 70% of correct responses among those men who reported having ever heard of HPV. Variables that achieved statistical significance in the bivariate analysis (p<0.05) were included in the multivariate logistic regression model. Results Although 52.5% of men reported having heard of HPV infection before the survey, only 29.3% of this sub-group had an adequate knowledge of HPV. Most men did not know that HPV is a risk factor for anal (38.7%), penile (50.0%) and oral (72.6%) cancer. Factors associated with adequate knowledge of HPV in age-adjusted models were being men who have sex with men (MSM) (OR=2.6;95%CI=1.1-6.1), self-report of genital warts (OR=3.2;95%CI=1.3-7.9) and herpes (OR=7.4;95% CI=2.2-25.1). MSM was marginally associated with adequate knowledge (OR=2.3;95% CI=0.9-5.9) and self-report of herpes remained significantly associated (OR=5.0;95%CI=1.3-18.4) in multivariate logistic regression analysis. Conclusions Awareness and knowledge of HPV was very low in this group of men. Interventions to increase knowledge and awareness in this group are necessary to promote preventive practices for HPV-related cancers in high-risk groups.

Abstract
Male circumcision consists of the surgical removal of some, or all, of the foreskin (or prepuce) from the penis. It is one of the most common procedures in the world. In the United States, the procedure is commonly performed during the newborn period. In 2007, the American Academy of Pediatrics (AAP) convened a multidisciplinary workgroup of AAP members and other stakeholders to evaluate the evidence regarding male circumcision and update the AAP's 1999 recommendations in this area. The Task Force included AAP representatives from specialty areas as well as members of the AAP Board of Directors and liaisons representing the American Academy of Family Physicians, the American College of Obstetricians and Gynecologists, and the Centers for Disease Control and Prevention. The Task Force members identified selected topics relevant to male circumcision and conducted a critical review of peer-reviewed literature by using the American Heart Association's template for evidence evaluation. Evaluation of current evidence indicates that the health benefits of newborn male circumcision outweigh the risks; furthermore, the benefits of newborn male circumcision justify access to this procedure for families who choose it. Specific benefits from male circumcision were identified for the prevention of urinary tract infections, acquisition of HIV, transmission of some sexually transmitted infections, and penile cancer. Male circumcision does not appear to adversely affect penile sexual function/sensitivity or sexual satisfaction. It is imperative that those providing circumcision are adequately trained and that both sterile techniques and effective pain management are used. Significant acute complications are rare. In general, untrained providers who perform circumcisions have more complications than well-trained providers who perform the procedure, regardless of whether the former are physicians, nurses, or traditional religious providers. Parents are entitled to factually correct, nonbiased information about circumcision and should receive this information from clinicians before conception or early in pregnancy, which is when parents typically make circumcision decisions. Parents should determine what is in the best interest of their child. Physicians who counsel families about this decision should provide assistance by explaining the potential benefits and risks and ensuring that parents understand that circumcision is an elective procedure. The Task Force strongly recommends the creation, revision, and enhancement of educational materials to assist parents of male infants with the care of circumcised and uncircumcised penises. The Task Force also strongly recommends the development of educational materials for providers to enhance practitioners' competency in discussing circumcision's benefits and risks with parents. The Task Force made the following recommendations:Evaluation of current evidence indicates that the health benefits of newborn male circumcision outweigh the risks, and the benefits of newborn male circumcision justify access to this procedure for those families who choose it. Parents are entitled to factually correct, nonbiased information about circumcision that should be provided before conception and early in pregnancy, when parents are most likely to be weighing the option of circumcision of a male child. Physicians counseling families about elective male circumcision should assist parents by explaining, in a nonbiased manner, the potential benefits and risks and by ensuring that they understand the elective nature of the procedure. Parents should weigh the health benefits and risks in light of their own religious, cultural, and personal preferences, as the medical benefits alone may not outweigh these other considerations for individual families. Parents of newborn boys should be instructed in the care of the penis, regardless of whether the newborn has been circumcised or not. Elective circumcision should be performed only if the infant's condition is stable and healthy. Male circumcision should be performed by trained and competent practitioners, by using sterile techniques and effective pain management. Analgesia is safe and effective in reducing the procedural pain associated with newborn circumcision; thus, adequate analgesia should be provided whenever newborn circumcision is performed.Nonpharmacologic techniques (eg, positioning, sucrose pacifiers) alone are insufficient to prevent procedural and postprocedural pain and are not recommended as the sole method of analgesia. They should be used only as analgesic adjuncts to improve infant comfort during circumcision. If used, topical creams may cause a higher incidence of skin irritation in low birth weight infants, compared with infants of normal weight; penile nerve block techniques should therefore be chosen for this group of newborns. Key professional organizations (AAP, the American Academy of Family Physicians, the American College of Obstetricians and Gynecologists, the American Society of Anesthesiologists, the American College of Nurse Midwives, and other midlevel clinicians such as nurse practitioners) should work collaboratively to:Develop standards of trainee proficiency in the performance of anesthetic and procedure techniques, including suturing; Teach the procedure and analgesic techniques during postgraduate training programs; Develop educational materials for clinicians to enhance their own competency in discussing the benefits and risks of circumcision with parents; Offer educational materials to assist parents of male infants with the care of both circumcised and uncircumcised penises. The preventive and public health benefits associated with newborn male circumcision warrant third-party reimbursement of the procedure. The American College of Obstetricians and Gynecologists has endorsed this technical report.
