Abstract
BACKGROUND Previous studies examining the association between male circumcision (MC) and human papillomavirus (HPV) infections have reported inconsistent results. We used data from the HPV Infection and Transmission Among Couples Through Heterosexual Activity (HITCH) cohort study to examine the association between MC and HPV infections in males and their female sexual partners. METHODS We enrolled monogamous couples in a longitudinal study between 2005 and 2011 in Montreal, Canada. We used logistic and Poisson regression models with propensity score adjustment to estimate odds ratios (ORs) and rate ratios for the association between MC and the prevalence, transmission, and clearance of HPV infections. RESULTS Four hundred thirteen couples were included in our study. The prevalence OR for the association between MC and baseline infections was 0.81 (95% confidence interval [CI], .56-1.16) in males and 1.05 (95% CI, .75-1.46) in females. The incidence rate ratio for infection transmission was 0.59 (95% CI, .16-2.20) for male-to-female transmission and 0.77 (95% CI, .37-1.60) for female-to-male transmission. The clearance rate ratio for clearance of infections was 0.81 (95% CI, .52-1.24). CONCLUSIONS We found little evidence of an association between MC and HPV infection prevalence, transmission, or clearance in males and females. Further longitudinal couple-based studies are required to investigate this association.

The role of infections in the causation of cancer in Kenya. Cancer Causes Control 2022; 33:1391-1400.

Abstract
Cancer constitutes a major health care burden in the world today with the situation worsening in resource poor settings as seen in most Sub-Saharan African (SSA) countries. Infections constitute by far the most common risk factors for cancer in SSA and being a typical country in this region, Kenya has experienced an upsurge in the incidence of various types of cancers in the last few decades. Although there is limited population-based data in Kenya of infections-associated cancers, this review provides an up-to-date literature-based discussion on infections-associated cancers, their pathogenesis, and preventive approaches in the country. The primary infectious agents identified are largely viral (human immunodeficiency virus, human papillomavirus (HPV), Kaposi's sarcoma-associated herpes virus, Epstein-Barr virus, hepatitis B virus (HBV), hepatitis C virus), and also bacterial: Helicobacter pylori and parasitic: Schistosomiasis haematobium. Cancers associated with infections in Kenya are varied but the predominant ones are Non-Hodgkin lymphoma, Kaposi's sarcoma, Hodgkin lymphoma, Burkitt's lymphoma, cervical, liver, and gastric cancers. The mechanisms of infections-induced carcinogenesis are varied but they mainly seem to stem from disruption of signaling, chronic inflammation, and immunosuppression. Based on our findings, actionable cancer-preventive measures that are economically feasible and aligned with existing infrastructure in Kenya include screening and treatment of infections, implementation of cancer awareness and screening, and vaccination against infections primarily HBV and HPV. The development of vaccines against other infectious agents associated with causation of cancer remains also as an important goal in cancer prevention.

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 To identify and critically appraise available clinical practice guidelines (CPGs) targeting male circumcision using the Appraisal of Guidelines for Research & Evaluation II (AGREE II) instrument. STUDY DESIGN A literature search was conducted using electronic databases, CPG databases, and national/international societies providing recommendations to guide clinical decision making for male circumcision. We selected pediatric-focused CPGs related to male circumcision published between January 2010 and December 2020. Non-English CPGs and publications involving narrative reviews, primary research, training manuals, patient and allied health professional guidelines, and technical guides were excluded from our search. Complete CPG documents (including full-text articles, supplemental documents, and associated information) were reviewed. Quality appraisal of CPGs was conducted in accordance with the AGREE II manual. RESULTS A total of 163 CPGs were identified, of which 93 were screened and 13 were reviewed. All AGREE II domains demonstrated good to excellent interrater reliability, with intraclass correlation coefficients ranging from 0.82 (95% CI, 0.72-0.89) to 0.93 (95% CI, 0.90-0.95). Most CPGs performed satisfactorily in the clarity of presentation domain and performed poorly in the applicability and editorial independence domains. The top 3 CPGs identified were those of the American Academy of Pediatrics, Centers for Disease Control and Prevention, and Canadian Urological Association. Consistencies among the CPGs were demonstrated across most recommendations. CONCLUSIONS Current CPGs are of variable quality, and our findings should be taken into consideration by clinicians and health care professionals when selecting appropriate guidelines for male circumcision.

Abstract
OBJECTIVE Male circumcision (MC) reduces acquisition of HIV-1 in heterosexual men by at least 60%, but the biological mechanism for this protection is incompletely understood. Previous studies have shown that a larger foreskin size, increased abundance of anaerobic bacteria in the sub-preputial space, and higher levels of pro-inflammatory cytokines on the penis are all prospectively associated with risk of HIV-1 acquisition. Since coverage of the glans on the non-erect penis is dependent on foreskin size, a larger foreskin could result in a less aerobic environment that might preferentially support anaerobic bacterial growth and induce inflammation. We therefore assessed the relationship between foreskin size, penile microbiome composition and local inflammation. METHODS This is a retrospective, cross-sectional analysis of 82 HIV-uninfected men who participated in a randomized trial of MC for HIV-1 prevention in Rakai, Uganda between 2003-2006. Sub-preputial swabs were collected prior to MC and assessed for cytokines (multiplexed immunosorbent assay) and bacterial load (qPCR) and taxon abundance (sequencing). Foreskin size was measured immediately after MC. RESULTS Foreskin surface area did not correlate with total bacterial load (rho = 0.05) nor the abundance of key taxa of bacteria previously associated with HIV-1 risk (rho = 0.04-0.25). Foreskin surface area also did not correlate with sub-preputial cytokine concentrations previously associated with HIV-1 risk (IL-8 rho = 0.05). CONCLUSIONS Larger foreskin size is not associated with either increased penile anaerobes or pro-inflammatory cytokines. These data suggest that foreskin size does not increase HIV-1 risk through changes in penile microbiome composition or penile inflammation.

Abstract
OBJECTIVE To systematically evaluate evidence against male circumcision (MC). METHODS We searched PubMed, Google Scholar, EMBASE and Cochrane databases. RESULTS Database searches retrieved 297 publications for inclusion. Bibliographies of these yielded 101 more. After evaluation we found: Claims that MC carries high risk were contradicted by low frequency of adverse events that were virtually all minor and easily treated with complete resolution. Claims that MC causes psychological harm were contradicted by studies finding no such harm. Claims that MC impairs sexual function and pleasure were contradicted by high-quality studies finding no adverse effect. Claims disputing the medical benefits of MC were contradicted by a large body of high-quality evidence indicating protection against a wide range of infections, dermatological conditions, and genital cancers in males and the female sexual partners of men. Risk-benefit analyses reported that benefits exceed risks by 100-200 to 1. To maximize benefits and minimize risks, the evidence supported early infant MC rather than arguments that the procedure should be delayed until males are old enough to decide for themselves. Claims that MC of minors is unethical were contradicted by balanced evaluations of ethical issues supporting the rights of children to be provided with low-risk, high-benefit interventions such as MC for better health. Expert evaluations of case-law supported the legality of MC of minors. Other data demonstrated that early infant MC is cost-saving to health systems. CONCLUSIONS Arguments opposing MC are supported mostly by low-quality evidence and opinion, and are contradicted by strong scientific evidence.

Abstract
Background The majority of individuals who seek voluntary medical male circumcision (VMMC) services in sub-Saharan Africa are adolescents (ages 10–19 years). However, adolescents who obtain VMMC services report receiving little information on human immunodeficiency virus (HIV) prevention and care. In this study, we assessed the perceptions of VMMC facility managers and providers about current training content and their perspectives on age-appropriate adolescent counseling. Methods Semistructured in-depth interviews were conducted with 33 VMMC providers in Tanzania (n = 12), South Africa (n = 9), and Zimbabwe (n = 12) and with 4 key informant facility managers in each country (total 12). Two coders independently coded the data thematically using a 2-step process and Atlas.ti qualitative coding software. Results Providers and facility managers discussed limitations with current VMMC training, noting the need for adolescent-specific guidelines and counseling skills. Providers expressed hesitation in communicating complete sexual health information—including HIV testing, HIV prevention, proper condom usage, the importance of knowing a partner’s HIV status, and abstinence from sex or masturbation during wound healing—with younger males (aged <15 years) and/or those assumed to be sexually inexperienced. Many providers revealed that they did not assess adolescent clients’ sexual experience and deemed sexual topics to be irrelevant or inappropriate. Providers preferred counseling younger adolescents with their parents or guardians present, typically focusing primarily on wound care and procedural information. Conclusions Lack of training for working with adolescents influences the type of information communicated. Preconceptions hinder counseling that supports comprehensive HIV preventive behaviors and complete wound care information, particularly for younger adolescents.

Abstract
Background Flat penile lesions (FPL) in heterosexual men are thought to play a role in the transmission of HPV. We investigated the association between FPL and penile HPV, and explored determinants of FPL in men who have sex with men (MSM). Methods In 2015–2016, MSM were recruited based on HIV and penile HPV status in a previous cohort. MSM self-completed a questionnaire. Peniscopy was performed after application of acetic acid to visualize FPL. Penile physician-collected samples were tested for HPV-DNA using the highly sensitive SPF10-PCR DEIA/LiPA25 system. HPV viral load (VL) was determined using a quantitative type-specific (q)PCR targeting the L1-region. Presence of HPV and HIV, HPV VL and circumcision status were compared between MSM with and without FPL. Results We included 116 MSM, of whom 59/116 (51%) MSM were HIV-positive and 54/116 (47%) had FPL. A penile HPV infection was present in 31/54 (57%) MSM with FPL and 34/62 (55%) MSM without FPL (p = 0.8). There was no difference between MSM with and without FPL regarding presence of penile HPV infection, HPV VL, HIV status or circumcision status (p > 0.05 for all). Conclusion Among MSM in Amsterdam, we found no association between FPL and penile HPV, HPV VL, HIV status or circumcision status.

Does Male Circumcision Reduce Women's Risk of Sexually Transmitted Infections, Cervical Cancer, and Associated Conditions? Front Public Health 2019; 7:4. [PMID: 30766863 PMCID: PMC6365441 DOI: 10.3389/fpubh.2019.00004] [Citation(s) in RCA: 26] [Impact Index Per Article: 5.2] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/05/2018] [Accepted: 01/04/2019] [Indexed: 12/16/2022] Open
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.

Prevalence and Risk Factors of Human Papillomavirus in Male Patients: A Systematic Review and Meta-Analysis. INTERNATIONAL JOURNAL OF ENVIRONMENTAL RESEARCH AND PUBLIC HEALTH 2018; 15:ijerph15102210. [PMID: 30309014 PMCID: PMC6210641 DOI: 10.3390/ijerph15102210] [Citation(s) in RCA: 34] [Impact Index Per Article: 5.7] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 08/08/2018] [Revised: 09/30/2018] [Accepted: 10/02/2018] [Indexed: 12/11/2022]
Abstract
Human papillomavirus (HPV) is one of the most prevalent sexually transmitted infections. Although the research focus has been on women, men are also affected. Thus, the aim was to estimate the prevalence of HPV in men and to analyse its risk factors. A systematic review with meta-analysis was performed. The main health science databases were consulted. The search terms were was: "papilloma virus AND (prevalence OR risk factors) AND men". The final sample of studies was n = 16 and the men sample for the meta-analysis was n = 18,106. The meta-analysis revealed a prevalence of 49% (95% Confidence Interval (CI): 35⁻64%) of any type of human papillomavirus in men and 35% (95% CI: 26⁻45%) of high-risk human papillomavirus in men. The included studies showed that stable sexual habits, circumcision and condom use are protective factors against HPV. In addition, there is a certain positive association with tobacco use and the early initiation of sexual intercourse. In conclusion, the prevalence of HPV in men is high. The risk factors for HPV infection are sexual promiscuity, early sexual debut, absence of circumcision, lack of condom use and smoking. Further study in this field about the effectiveness of the vaccine and health education should be conducted.

Abstract
Background Limited data are available on human papillomavirus (HPV) infection among human immunodeficiency virus (HIV)-negative or HIV-positive couples followed longitudinally. Methods Genital HPV was assessed in 725 concordant HIV-negative couples and 209 HIV-positive couples enrolled in a male circumcision trial in Rakai, Uganda, using the Roche Linear Array assay, which detects 37 HPV genotypes. Human papillomavirus prevalence and determinants of genotype-specific concordance were assessed at annual visits. Cumulative detection of HPV genotypes over 2 years was also assessed. Results At enrollment, HPV infection was detected in 54% of HIV-negative women, 56% of HIV-negative men, and 93% of HIV-positive men and women. For HIV-negative couples, genotypic concordance was 30% at baseline (n = 219/725) and declined significantly with age (adjusted prevelance risk ratio [adjPRR] = 0.53; 95% confidence interval [CI] = 0.28-0.93 comparing women aged >40 years to those aged 15-19 years) and male circumcision (adjPRR = 0.60; 95% CI = 0.47-0.77) and increased among couples with recent intercourse (adjPRR = 1.26; 95% CI = 1.04-1.53). These associations were not seen in HIV-positive couples. Among couples with HPV results at all visits, ≥1 of the same genotypes were detected in both partners in 60% of HIV-negative couples and 96% of HIV-positive couples over 2 years. Conclusion Human papillomavirus genotype-specific concordance is more common in HIV-positive couples, and irrespective of HIV status, the majority of couples exhibit HPV concordance over 2 years.

Abstract
Frisch and Earp, opponents of male circumcision, have criticized draft recommendations from the CDC that advocate counseling men and parents of newborn boys in the United States about the benefits and risks of male circumcision. We provide a rebuttal to Frisch and Earp's criticisms and contend that the recommendations are entirely appropriate and merit consideration for policy development.

Abstract
Despite access to safe medical male circumcision (MMC) and proven effectiveness of the procedure in reducing acquisition of HIV and other sexually transmitted infections, uptake remains suboptimal in many settings in sub-Saharan Africa, including Rakai District, Uganda. This study explored multilevel barriers and facilitators to MMC in focus group discussions (FGDs) (n = 35 groups) in Rakai. Focus groups were conducted from May through July 2012 with adolescent and adult males, with a range of HIV risk and reproductive health service use profiles, and with adolescent and adult females. Data were analyzed using Atlas.ti and an inductive approach. Participants' discussions produced several key themes representing multilevel influences that may facilitate or create barriers to uptake of MMC. These include availability of MMC services, economic costs, masculine ideals, religion, and social influence. Understanding how males and females view MMC is a crucial step towards increasing uptake of the procedure and reducing disease transmission.

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 investigated the ethnic differences in the risk of several cancers in the population of Nairobi, Kenya, using data from the Nairobi Cancer Registry. The registry records the variable "Tribe" for each case, a categorisation that includes, as well as 22 tribal groups, categories for Kenyans of European and of Asian origin, and non-Kenyan Africans. Tribes included in the final analysis were Kikuyu, Kamba, Kisii, Kalenjin, Luo, Luhya, Somalis, Asians, non-Kenyans, Caucasians, Other tribes and unknown. The largest group was taken as the reference category for the calculation of odds ratios; this was African Kenyans (for comparisons by race), and Kikuyus (the tribe with the largest numbers of cancer registrations (38% of the total)) for comparisons between the Kenyan tribes. P-values are obtained from the Wald test. Cancers that were more common among the white population than in black Kenyans were skin cancers and cancers of the bladder, while cancers that are more common in Kenyan Asians include colorectal, lung, breast, ovary, corpus uteri and non-Hodgkin lymphoma. Cancers that were less common among Asians and Caucasians were oesophagus, stomach and cervix cancer. Within the African population, there were marked differences in cancer risk by tribe. Among the tribes of Bantu ethnicity, the Kamba had higher risks of melanoma, Kaposi sarcoma, liver and cervix cancer, and lower risks of oesophagus, stomach, corpus uteri and nervous system cancers. Luo and Luhya had much higher odds of Kaposi sarcoma and Burkitt lymphoma.

Abstract
AIM To determine whether recent evidence-based United States policies on male circumcision (MC) apply to comparable Anglophone countries, Australia and New Zealand. METHODS Articles in 2005 through 2015 were retrieved from PubMed using the keyword "circumcision" together with 36 relevant subtopics. A further PubMed search was performed for articles published in 2016. Searches of the EMBASE and Cochrane databases did not yield additional citable articles. Articles were assessed for quality and those rated 2+ and above according to the Scottish Intercollegiate Grading System were studied further. The most relevant and representative of the topic were included. Bibliographies were examined to retrieve further key references. Randomized controlled trials, recent high quality systematic reviews or meta-analyses (level 1++ or 1+ evidence) were prioritized for inclusion. A risk-benefit analysis of articles rated for quality was performed. For efficiency and reliability, recent randomized controlled trials, meta-analyses, high quality systematic reviews and large well-designed studies were used if available. Internet searches were conducted for other relevant information, including policies and Australian data on claims under Medicare for MC. RESULTS Evidence-based policy statements by the American Academy of Pediatrics (AAP) and the Centers for Disease Control and Prevention (CDC) support infant and later age male circumcision (MC) as a desirable public health measure. Our systematic review of relevant literature over the past decade yielded 140 journal articles that met our inclusion criteria. Together, these showed that early infant MC confers immediate and lifelong benefits by protecting against urinary tract infections having potential adverse long-term renal effects, phimosis that causes difficult and painful erections and "ballooning" during urination, inflammatory skin conditions, inferior penile hygiene, candidiasis, various sexually transmissible infections in both sexes, genital ulcers, and penile, prostate and cervical cancer. Our risk-benefit analysis showed that benefits exceeded procedural risks, which are predominantly minor, by up to 200 to 1. We estimated that more than 1 in 2 uncircumcised males will experience an adverse foreskin-related medical condition over their lifetime. Wide-ranging evidence from surveys, physiological measurements, and the anatomical location of penile sensory receptors responsible for sexual sensation strongly and consistently suggested that MC has no detrimental effect on sexual function, sensitivity or pleasure. United States studies showed that early infant MC is cost saving. The evidence supporting early infant MC has further strengthened since the positive AAP and CDC reviews. CONCLUSION Affirmative MC policies are needed in Australia and New Zealand. Routine provision of accurate, unbiased education, and access in public hospitals, will maximize health and financial benefits.

Abstract
BACKGROUND Whether higher penile human papillomavirus (HPV) viral load is associated with a lower rate of HPV clearance remains unknown. OBJECTIVES We examined the association between penile HPV16 and HPV18 viral load and subsequent HPV clearance in uncircumcised Kenyan men. STUDY DESIGN Participants were human immunodeficiency virus (HIV)-seronegative, sexually active, 18- to 24-year-old men randomized to the control arm of a male circumcision trial in Kisumu, Kenya. Men provided exfoliated penile cells from two anatomical sites (glans/coronal sulcus and shaft) every 6 months for 2 years. GP5+/6+ polymerase chain reaction was used to identify 44 HPV-DNA types. Human papillomavirus viral load testing was conducted using a LightCyler real-time polymerase chain reaction assay; viral load was classified as high (>250 copies/scrape) or low (≤250 copies/scrape), for nonquantifiable values. The Kaplan-Meier method and Cox regression modeling were used to examine the association between HPV viral load and HPV clearance. RESULTS A total of 1097 men, with 291 HPV16 and 131 HPV18 cumulative infections over 24 months were analyzed. Human papillomavirus clearance at 6 months after first HPV detection was lower for high versus low viral load HPV16 infections in the glans (adjusted hazard ratio [aHR], 0.65; 95% confidence interval [CI], 0.46-0.92)] and shaft (aHR, 0.44; 95% CI, 0.16-0.90), and HPV18 infections in the glans (aHR, 0.05; 95% CI, 0.01-0.17). DISCUSSION High versus low HPV viral load was associated with a reduced HPV clearance for HPV16 infections in the glans and shaft, and for HPV18 infections in the glans, among young uncircumcised men. Reduced clearance of high viral load HPV16 and HPV18 infections in men may increase HPV transmission to their female partners as well as enhance the development of penile lesions in comparison to men with low viral load HPV infections.

Abstract
We evaluate recent claims opposing infant male circumcision, a procedure now supported by the evidence-based policy of the American Academy of Pediatrics. We find those criticisms depend on speculative claims about the foreskin and obfuscation of the strong scientific evidence supporting pediatric policy development. An argument that circumcision should be delayed to allow a boy to make up his own mind as an adult fails to appreciate the psychological, scheduling and financial burdens later circumcision entails, so reducing the likelihood that it will occur. In contrast, early infant circumcision is convenient, safer, quicker, lower risk, healing is faster, cosmetic outcome is routinely good and the lifetime benefits accrue immediately. Benefits include reduction in urinary tract infections, inflammatory skin conditions, foreskin problems, and, when older, substantial protection against sexually transmitted infections and genital cancers in the male and his female sexual partners. Some authorities regard the failure to offer parents early infant circumcision as unethical, just as it would be unethical to fail to encourage the vaccination of children. In conclusion, the criticisms of evidence-based infant male circumcision policy are seriously flawed and should be dismissed as unhelpful to evidence-based development and implementation of pediatric policy intended to improve public health and individual wellbeing.

Abstract
Male circumcision (MC) reduces the risk of HIV and other sexually transmitted infections (STIs), including human papillomavirus (HPV) and herpes simplex virus type 2 (HSV-2), and is recommended as an important component of a comprehensive package of HIV prevention interventions. While computer modeling has demonstrated that substantial reductions in HIV could be achieved with rapid scale-up of MC services in sub-Saharan Africa, scale-up has lagged due to scarcity of trained providers coupled with relative technical difficulty of recommended surgical MC techniques. Simplified techniques, such as devices, have the potential to allow for a more rapid roll-out of MC. One such device is the Shang Ring, a novel disposable MC device that eliminates the need for suturing and has been on the Chinese market since 2005. Results from Chinese studies have demonstrated that the Shang Ring is both safe and easy to use. Since 2008, a series of studies using the Shang Ring for adult MC have been carried out in Kenya, Uganda and Zambia, according to guidelines established by World Health Organization (WHO) for clinical evaluation of new devices for adult MC. These include a proof of concept study, a study of delayed removal of the Shang Ring, two studies comparing Shang Ring circumcision to conventional surgical approaches, and a large field trial to evaluate safety of Shang Ring circumcision during routine service delivery. Results from these studies demonstrate that the Shang Ring has an excellent safety profile and that Shang Ring circumcision is relatively easy to teach and learn, making Shang Ring MC an appealing technique for use in sub-Saharan Africa where doctors are in short supply and non-physician providers such as nurses and clinical officers are playing a major role in providing MC through task shifting. Shang Ring MC and device removals were uneventfully performed by trained nurses and clinical officers, who preferred the Shang Ring to conventional surgical techniques. Adverse event rates were similar to those observed with conventional surgical circumcision and were managed with, at most, minor interventions, resolving with no long-term sequale. Perhaps one of the biggest advantages of the Shang Ring is the relatively short 3-6 minutes procedure time. Importantly, men also preferred the Shang Ring compared to conventional circumcision and satisfaction with cosmetic appearance of their circumcised penis was very high. The vast majority of participants in studies in Africa as well as China have reported few problems and little disruption to daily life while wearing the device. The Shang Ring holds great promise as an innovative technology that has the potential to facilitate the safe and effective scale-up of circumcision services in settings where MC is not widely used and where the burden of HIV-disease is high.

Abstract
Penile cancer is a rare disease, accounting for ~1% of all malignancies in men. Poor awareness of the condition among the public and clinicians often causes long delays in diagnosis and treatment, which may result in the development of advanced disease that might require extensive and emasculating surgery. In the UK, the development of supraregional penile cancer centres has pooled resources and expertise, which has led to considerable improvements in our understanding and management of this rare condition over the past decade. However, significant gaps in our knowledge still exist. Several areas of diagnosis and management remain areas of controversy, ranging from preventive strategies and treatment of premalignant disease to the assessment of lymph node involvement and the management of advanced disease.

Abstract
BACKGROUND Male circumcision confers protection against HIV, sexually transmitted infections, and urinary tract infections. Compared with circumcision of postneonates (>28 days), circumcision of neonates is associated with fewer complications and usually performed with local rather than general anesthesia. We assessed circumcision of commercially insured males during the neonatal or postneonatal period. METHODS We analyzed 2010 MarketScan claims data from commercial health plans, using procedural codes to identify circumcisions performed on males aged 0 to 18 years, and diagnostic codes to assess clinical indications for the procedure. Among circumcisions performed in the first year of life, we estimated rates for neonates and postneonates. We estimated the percentage of circumcisions by age among males who had circumcisions in 2010, and the mean payment for neonatal and postneonatal procedures. RESULTS We found that 156,247 circumcisions were performed, with 146,213 (93.6%) in neonates and 10,034 (6.4%) in postneonates. The neonatal circumcision rate was 65.7%, and 6.1% of uncircumcised neonates were circumcised by their first birthday. Among postneonatal circumcisions, 46.6% were performed in males younger than 1 year and 25.1% were for nonmedical indications. The mean payment was $285 for a neonatal and $1885 for a postneonatal circumcision. CONCLUSIONS The large number of nonmedical postneonatal circumcisions suggests that neonatal circumcision might be a missed opportunity for these boys. Delay of nonmedical circumcision results in greater risk for the child, and a more costly procedure. Discussions with parents early in pregnancy might help them make an informed decision about circumcision of their child.

Abstract
BACKGROUND Circumcision and lower human papillomavirus (HPV) viral loads in men are possibly associated with a reduced risk of HPV transmission to women. However, the association between male circumcision and HPV viral load remains unclear. METHODS Swab specimens from the glans and shaft of the penis were collected from men enrolled in a circumcision trial in Kisumu, Kenya. GP5+/6+ polymerase chain reaction (PCR) was used to identify HPV DNA types. HPV-16 and HPV-18 loads were measured with a LightCycler real-time PCR and classified as high (>250 copies/scrape) or low (≤250 copies/scrape). RESULTS A total of 1159 men were randomly assigned to undergo immediate circumcision, and 1140 men were randomly assigned to the control arm (these individuals were asked to remain uncircumcised until the study ended). The hazard of acquisition of high-viral load infections in the glans was lower in the circumcision arm, compared with the control arm, for HPV-16 (hazard ratio [HR], 0.32 [95% confidence interval {CI}, .20-.49]) and HPV-18 (HR, 0.34 [95% CI, .21-.54]). The 6-month risk of HPV persistence among men with high-viral load infections in the glans at baseline was lower in the circumcision arm, compared with the control arm, for HPV-16 (risk ratio [RR], 0.36 [95% CI, .18-.72]) and HPV-18 (RR 0.34 [95% CI, .13-.86]). Weaker and less precise results were obtained for shaft samples. CONCLUSIONS Male circumcision could potentially reduce the risk of HPV transmission to women by reducing the hazard of acquisition, and the risk of persistence of high-HPV viral load infections in the glans in men.

Abstract
In a recent issue of the Journal of Medical Ethics,Svoboda and Van Howe commented on the 2012 changein the American Academy of Pediatrics (AAP) policy on newborn male circumcision, in which the AAP stated that benefits of the procedure outweigh the risks. Svoboda and Van Howe disagree with the AAP conclusions. We show here that their arguments against male circumcision are based on a poor understanding of epidemiology,erroneous interpretation of the evidence, selective citation of the literature, statistical manipulation of data, and circular reasoning. In reality, the scientific evidence indicates that male circumcision, especially when performed in the newborn period, is an ethically and medically sound low-risk preventive health procedure conferring a lifetime of benefits to health and well-being.Policies in support of parent-approved elective newborn circumcision should be embraced by the medical,scientific and wider communities.

Abstract
We critically evaluate a recent article by Van Howe involving 12 meta-analyses that concludes, contrary to current evidence, that male circumcision increases the risk of various common sexually transmitted infections (STIs). Our detailed scrutiny reveals that these meta-analyses (1) failed to include results of all relevant studies, especially data from randomized controlled trials, (2) introduced bias through use of inappropriate control groups, (3) altered original data, in the case of human papillomavirus (HPV), by questionable adjustments for "sampling bias," (4) failed to control for confounders through use of crude odds ratios, and (5) used unnecessarily complicated methods without adequate explanation, so impeding replication by others. Interventions that can reduce the prevalence of STIs are important to international health. Of major concern is the global epidemic of oncogenic types of HPV that contribute to the burden of genital cancers. Meta-analyses, when well conducted, can better inform public health policy and medical practice, but when seriously flawed can have detrimental consequences. Our critical evaluation leads us to reject the findings and conclusions of Van Howe on multiple grounds. Our timely analysis thus reaffirms the medical evidence supporting male circumcision as a desirable intervention for STI prevention.

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
OBJECTIVES High-risk human papillomavirus (HR-HPV) viral load is associated with HR-HPV transmission and HR-HPV persistence in women. It is unknown whether HR-HPV viral load is associated with persistence in HIV-negative or HIV-positive men. METHODS HR-HPV viral load and persistence were evaluated among 703 HIV-negative and 233 HIV-positive heterosexual men who participated in a male circumcision trial in Rakai, Uganda. Penile swabs were tested at baseline and 6, 12 and 24 months for HR-HPV using the Roche HPV Linear Array, which provides a semiquantitative measure of HPV shedding by hybridisation band intensity (graded: 1-4). Prevalence risk ratios (PRR) were used to estimate the association between HR-HPV viral load and persistent detection of HR-HPV. RESULTS HR-HPV genotypes with high viral load (grade:3-4) at baseline were more likely to persist than HR-HPV genotypes with low viral load (grade: 1-2) among HIV-negative men (month 6: adjPRR=1.83, 95% CI 1.32 to 2.52; month 12: adjPRR=2.01, 95% CI 1.42 to 3.11), and HIV-positive men (month 6: adjPRR=1.33, 95% CI 1.06 to 1.67; month 12: adjPRR=1.73, 95% CI 1.18 to 2.54). Long-term persistence of HR-HPV was more frequent among HIV-positive men compared with HIV-negative men (month 24: adjPRR=2.27, 95% CI 1.47 to 3.51). Persistence of newly detected HR-HPV at the 6-month and 12-month visits with high viral load were also more likely to persist to 24 months than HR-HPV with low viral load among HIV-negative men (adjPRR=1.67, 95% CI 0.88 to 3.16). CONCLUSIONS HR-HPV genotypes with high viral load are more likely to persist among HIV-negative and HIV-positive men, though persistence was more common among HIV-positive men overall. The results may explain the association between high HR-HPV viral load and HR-HPV transmission.

Abstract
Early achievements in biomedical approaches for HIV prevention included physical barriers (condoms), clean injection equipment (both for medical use and for injection drug users), blood and blood product safety, and prevention of mother-to-child transmission. In recent years, antiretroviral drugs to reduce the risk of transmission (when the infected person takes the medicines; treatment as prevention) or reduce the risk of acquisition (when the seronegative person takes them; preexposure prophylaxis) have proven to be efficacious. Circumcision of men has also been a major tool relevant for higher prevalence regions such as sub-Saharan Africa. Well-established prevention strategies in the control of sexually transmitted diseases and tuberculosis are highly relevant for HIV (ie, screening, linkage to care, early treatment, and contact tracing). Unfortunately, only slow progress is being made in some available HIV-prevention strategies such as family planning for HIV-infected women who do not want more children and prevention of mother-to-child HIV transmission. Current studies seek to integrate strategies into approaches that combine biomedical, behavioral, and structural methods to achieve prevention synergies. This review identifies the major biomedical approaches demonstrated to be efficacious that are now available. We also highlight the need for behavioral risk reduction and adherence as essential components of any biomedical approach.

Abstract
Infant male circumcision (MC) is an important issue guided by Royal Australasian College of Physicians (RACP) policy. Here we analytically review the RACP's 2010 policy statement 'Circumcision of infant males'. Comprehensive evaluation in the context of published research was used. We find that the Statement is not a fair and balanced representation of the literature on MC. It ignores, downplays, obfuscates or misrepresents the considerable evidence attesting to the strong protection MC affords against childhood urinary tract infections, sexually transmitted infections (human immunodeficiency virus, human papilloma virus, herpes simplex virus type 2, trichomonas and genital ulcer disease), thrush, inferior penile hygiene, phimosis, balanoposthitis and penile cancer, and in women protection against human papilloma virus, herpes simplex virus type 2, bacterial vaginosis and cervical cancer. The Statement exaggerates the complication rate. Assertions that 'the foreskin has a functional role' and 'is a primary sensory part of the penis' are not supported by research, including randomised controlled trials. Instead of citing these and meta-analyses, the Statement selectively cites poor quality studies. Its claim, without support from a literature-based risk-benefit analysis, that the currently available evidence does 'not warrant routine infant circumcision in Australia and New Zealand' is misleading. The Statement fails to explain that performing MC in the neonatal period using local anaesthesia maximises benefits, safety, convenience and cost savings. Because the RACP's policy statement is not a fair and balanced representation of the current literature, it should not be used to guide policy. In the interests of public health and individual well-being, an extensive, comprehensive, balanced review of the scientific literature and a risk-benefit analysis should be conducted to formulate policy.

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
Male circumcision (MC) reduces high-risk human papillomavirus (HR-HPV) infection in female partners. We evaluated the intensity of HR-HPV viral DNA load in HIV-negative, HR-HPV-positive female partners of circumcised and uncircumcised men. HIV-negative men and their female partners were enrolled in randomized trials of MC in Rakai, Uganda. Vaginal swabs were tested for HR-HPV genotypes by Roche HPV Linear Array which provides a semi-quantitative measure of HPV DNA by the intensity of genotype-specific bands (graded:1-4). We assessed the effects of MC on female HR-HPV DNA load by comparing high intensity linear array bands (3-4) to low intensity bands (1-2) using an intention-to-treat analysis. Prevalence risk ratios (PRR) of high intensity bands in partners of intervention versus control arm men were estimated using log-binomial regression with robust variance. The trial included 335 women with male partners in the intervention arm and 340 in the control arm. At enrollment, the frequency of HR-HPV high intensity linear array bands was similar in both study arms. At 24 months follow-up, the prevalence of high intensity bands among women with detectable HR-HPV was significantly lower in partners of intervention arm (42.7%) than control arm men (55.1%, PRR = 0.78, 95% CI 0.65-0.94, p = 0.02), primarily among incident HR-HPV infections (PRR = 0.66, 95% CI 0.50-0.87, p = 0.003), but not persistent infections (PRR = 1.02, 95% CI 0.83-1.24). Genotypes with high HR-HPV band intensity were more likely to persist (adjHR = 1.27 95% CI 1.07-1.50), irrespective of male partner circumcision status. MC reduces HR-HPV DNA load in newly infected female partners.

Abstract
HPV has carcinogenic effects at several anatomical sites in women and men. Whether the presence of HPV in the genitourinary tract of men is associated with a higher prostate cancer risk has been a matter of research for a long-time and the results are still not fully conclusive. Similarly, the question of the reservoir of HPV infection in men is not clearly resolved. HPV DNA presence and types were evaluated by means of polymerase chain reaction in the tissue of 146 patients with benign prostate hyperplasia and prostate cancer. HPV-specific antibodies were analyzed by enzyme-linked immunosorbent assay in the sera of all patients and 172 controls. In addition, 256 biopsies taken from non-tumorous tissues were analyzed. No statistically significant differences were observed in HPV DNA prevalence between patients with benign prostate hyperplasia (2%) and patients with prostatic cancer (2%; P = 1.000). The seropositivity rates did not differ significantly between groups of subjects except for antibodies against HPV 6 VLPs which were found more often in prostate cancer patients (adjusted P = 0.018). Similarly, no difference in the seroprevalence rates for HPV 16 E6 and/or E7 oncoproteins between groups of patients and healthy controls was detected. The overall HPV prevalence in 256 healthy tissue samples was 4%. The results indicate that HPV infection is not associated with prostate oncogenesis in men. However, they imply that multiple tissues of the male genitourinary tract may be important reservoirs for the transmission of some HPV types.

Abstract
Background Penile cancer (PC) is a rare cancer in western countries, but is more common in parts of the developing world. Due to its rarity and the consequent lack of randomized trials, current therapy is based on retrospective studies and small prospective trials. Design Studies of PC therapy were searched in PubMed and abstracts at major conferences. Results PC is generally an aggressive malignancy characterized by early locoregional lymph node (LN) spread and later metastases in distant sites. Given the strong predictive value of LN involvement for overall survival, evaluating regional LNs is critical. Advanced LN involvement is increasingly being treated with multimodality therapy incorporating chemotherapy and/or radiation. A single superior cisplatin-based regimen has not been defined. Further advances may occur with a better collaboration on an international scale and comprehensive understanding of tumor biology. To this end, the preventive role of circumcision and understanding of the oncogenic roles of Human Papilloma Virus-16, and smoking may yield advances. Preliminary data suggest a role for agents targeting epidermal growth factor receptor and angiogenesis. Conclusion Advances in therapy for PC will require efficient trial designs, synergistic collaboration, incentives to industry and the efforts of patient advocacy groups and venture philanthropists.

Abstract
OBJECTIVE To investigate the prevalence of high-risk (HR) and low-risk (LR) human papillomavirus (HPV) in prepuces of boys and men without any HPV related lesions. PATIENTS AND METHODS Between 2009 and 2011, a total collective of 250 boys and men were investigated in this prospective study. The samples were subdivided into 3 groups regarding their age, consisting of 125 (50%) children (0-10 years), 38 (15.2%) adolescents (11-20 years) and 87 (34.8%) adults (>20 years). In situ hybridization (ISH) was performed to detect HR and LR virus types within the epithelium, followed by microscopic interpretation and determination between episomal and integrative signal pattern. RESULTS Our results revealed high levels of HPV concentration (HR and LR) in all age groups: HR versus LR positivity was seen in 45.5 versus 35% (children), 60.6 versus 63.6% (adolescents) and 58.3 versus 48.6% (adults). The topmost rate of HR (59.8%)- and LR (50.6%)-positive probes was found in the group with high estimated sexual activity (>14 years). CONCLUSION Concerning the high prevalence of male HPV infection even in children, indicating non-sexual transmission pathways, inclusion of boys in the vaccination program seems to be required reducing their burden of HPV related disease.

Abstract
OBJECTIVES High-risk human papillomavirus (HR-HPV) infection is the most common sexually transmitted infection. Penile and cervical cancer rates are highest in sub-Saharan Africa. However, little is known about the impact of HIV infection on HR-HPV acquisition and clearance among heterosexual men. DESIGN HR-HPV incidence and clearance were evaluated in 999 men (776 HIV-negative and 223 HIV-positive) aged 15-49 years who participated in male circumcision trials in Rakai, Uganda. METHODS Penile swabs were tested for HR-HPV by Roche HPV Linear Array. A Poisson multivariable model was used to estimate adjusted incidence rate ratios (adjIRRs) and clearance risk ratios (adjRRs). RESULTS HR-HPV incidence was 66.5/100 person-years in HIV-positive men and 32.9/100 person-years among HIV-negative men [IRR=2.02, 95% confidence interval (CI) 1.67-2.44]. Incidence was higher in the unmarried men (adjIRR=1.73, 95% CI 1.19-2.52), and decreased with age (adjIRR for men >35 years=0.64, 95% CI 0.43-0.94) and male circumcision (adjIRR=0.70, 95% CI 0.55-0.89). HR-HPV clearance was 114.7/100 person-years for HIV-positive men and 170.2/100 person-years for HIV-negative men (risk ratio=0.67, 95% CI 0.59-0.77). HR-HPV clearance in HIV-negative men increased with circumcision (adjRR=1.48, 95% CI 1.26-1.74), HSV-2 infection (adjRR=1.20, 95% CI 1.01-1.44), and symptoms of urethral discharge (adjRR=1.35, 95% CI 1.06-1.73). Clearance of HR-HPV was significantly lower for unmarried men (adjRR 0.76, 95% CI 0.59-0.98). CONCLUSION HR-HPV is common among heterosexual Ugandan men, particularly the HIV-infected. HIV infection increases HR-HPV acquisition and reduces HR-HPV clearance. Promotion of male circumcision and additional prevention measures, such as HPV vaccination, is critical in sub-Saharan Africa.

Abstract
OBJECTIVES Human papillomavirus (HPV) infection causes genital warts, penile cancer and cervical cancer. Africa has one of the highest rates of penile and cervical cancers, but there are little data on high-risk human papillomavirus (HR-HPV) prevalence in heterosexual men. Knowledge of HR-HPV prevalence, risk factors and genotype distribution among heterosexual men is important to establish risk-reduction prevention strategies. METHODS 1578 uncircumcised men aged 15-49 years who enrolled in male circumcision trials in Rakai, Uganda, were evaluated for HR-HPV from swabs of the coronal sulcus/glans using Roche HPV Linear Array. Adjusted prevalence risk ratios (adjPRRs) were estimated using modified Poisson multivariable regression. RESULTS HPV prevalence (either high risk or low risk) was 90.7% (382/421) among HIV-positive men and 60.9% (596/978) among HIV-negative men (PRR 1.49, 95% CI 1.40 to 1.58). HIV-positive men had a significantly higher risk of infection with three or more HR-HPV genotypes (PRR=5.76, 95% CI 4.27 to 7.79). Among HIV-positive men, high-risk sexual behaviours were not associated with increased HR-HPV prevalence. Among HIV-negative men, HR-HPV prevalence was associated with self-reported genital warts (adjPRR 1.57, 95% CI 1.07 to 2.31). Among all men (both HIV negative and HIV positive), HR-HPV prevalence was associated with more than 10 lifetime sexual partners (adjPRR 1.30, 95% CI 1.01 to 1.66), consistent condom use (adjPRR 1.31, 95% CI 1.08 to 1.60) and HIV infection (adjPRR 1.80, 95% CI 1.60 to 2.02). HR-HPV prevalence was lower among men who reported no sexual partners during the past year (adjPRR 0.47, 95% CI 0.23 to 0.94). CONCLUSION The burden of HR-HPV infection is high among heterosexual men in sub-Saharan Africa and most pronounced among the HIV-infected individuals.

Abstract
The recent policy statement by the Cancer Council of Australia on infant circumcision and cancer prevention and the announcement that the quadrivalent human papillomavirus (HPV) vaccine will be made available for boys in Australia prompted us to provide an assessment of genital cancer prevention. While HPV vaccination of boys should help reduce anal cancer in homosexual men and cervical cancer in women, it will have little or no impact on penile or prostate cancer. Male circumcision can reduce cervical, penile and possibly prostate cancer. Promotion of both HPV vaccination and male circumcision will synergistically maximize genital cancer prevention.

Abstract
Despite over two decades of extensive research showing that male circumcision protects against heterosexual acquisition of HIV in men, and that includes findings from large randomized controlled trials leading to acceptance by the WHO/UNAIDS and the Cochrane Committee, opponents of circumcision continue to generate specious arguments to the contrary. In a recent issue of the Journal of Public Health in Africa, Van Howe and Storms claim that male circumcision will increase HIV infections in Africa. Here we review the statements they use in support of their thesis and show that there is no scientific basis to such an assertion. We also evaluate the statistics used and show that when these data are properly analyzed the results lead to a contrary conclusion affirming the major role of male circumcision in protecting against HIV infection in Africa. Researchers, policy makers and the wider community should rely on balanced scholarship when assessing scientific evidence. We trust that our assessment may help refute the claims by Van Howe and Storms, and provide reassurance on the importance of circumcision for HIV prevention.
