Fendereski K, Horns JJ, Driggs N, Lau G, Schaeffer AJ. Comparing Penile Problems in Circumcised vs. Uncircumcised Boys: Insights From a Large Commercial Claims Database With a Focus on Provider Type Performing Circumcision. J Pediatr Surg 2024; 59:161614. [PMID: 39084960 PMCID: PMC11486584 DOI: 10.1016/j.jpedsurg.2024.06.022] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 04/03/2024] [Revised: 06/25/2024] [Accepted: 06/29/2024] [Indexed: 08/02/2024]
Abstract
OBJECTIVES To compare penile problems in circumcised relative to uncircumcised boys, and to determine which providers performing the circumcision have fewer post-circumcision problems. METHODS CPT codes in the 2011-2020 MarketScan database were used to identify boys who had a circumcision. Uncircumcised control subjects of the same age, state of residence, and insurance type were selected. The primary outcome was a penile problem, defined as penis-specific infection, inflammation, and urethral stricture/stenosis, among others. The secondary outcomes were procedure-related complications limited to 28 days after circumcision, and whether post-circumcision problems varied by the clinician performing the procedure. ICD-9/10 diagnostic codes were used to identify these problems. RESULTS We identified ∼850,000 cases and ∼850,000 matched controls. Overall, the rate of penile problems within the first five years of life was 1.7% in circumcised boys versus 0.5% in uncircumcised boys (p < 0.05). Multivariable regression models showed that the risk of penile problems was 2.9-fold higher among circumcised compared to uncircumcised males (95%CI [2.8-3], p < 0.001). Compared to males circumcised by pediatricians, those circumcised by surgeons had 2.1-fold higher penile problems in the year after circumcision (95% CI [2-2.3], p < 0.001). Procedure-related complications within 28 days of circumcision were infrequent (0.5%), with the most common being penile edema (0.2%). CONCLUSIONS Penile problems are very infrequent in boys in the first five years of life. However, when they occur, they are 3x more likely to occur in circumcised boys relative to uncircumcised boys. Penile problems are more likely to occur in boys circumcised by surgeons. LEVELS OF EVIDENCE Level II. TYPE OF STUDY Prognosis study.

Abstract
BACKGROUND To evaluate the overall survival (OS) and construct a nomogram to predict the OS of patients with penile squamous cell carcinoma (PSCC). METHODS This retrospective study analyzed data of patients with PSCC from the First Affiliated Hospital of Soochow University between 2012 and 2022. R software was used to explore factors influencing OS in PSCC. Kaplan-Meier method and log-rank test were employed for OS estimation. Univariate and multivariate Cox proportional hazards regression analyses were performed to identify these factors. A nomogram was created to identify the independent prognostic factors. The model was evaluated by concordance index, receiver operating characteristic (ROC) curves, and calibration plots. RESULTS A total of 159 patients with T1/T2 PSCC were included in the analysis. Patients with T2/N2 stage, older age, larger tumor size, high preoperative systemic immune-inflammation index (SII), and poor preoperative nutrition had a higher incidence of poor OS. Age, T/N stage, tumor size, and SII were identified as independent prognostic indicators. A prognostic nomogram was formulated, and its predictive accuracy for estimating OS in PSCC patients was validated through ROC curves and calibration plots. CONCLUSION The nomograms, based on age, T/N stage, tumor size, and high preoperative SII, provide a valuable tool for predicting 1-, 2-, and 3-year OS in patients with T1/T2 PSCC without distant metastases.

Abstract
OBJECTIVES People with HIV (PWH) may have an increased burden of penile cancer. We aimed to evaluate the risk of penile cancer in PWH compared with that of the general population. DESIGN We conducted a nationwide retrospective matched cohort study of penile cancer incidence among veterans with HIV (VWH) compared with veterans without HIV. METHODS We compared penile cancer incidence rates in 44 173 VWH to those of veterans without HIV ( N = 159 443; 4 : 1 matched in age). We used Cox regression models to estimate hazard ratios and 95% confidence intervals (CIs) for associations with HIV infection and for penile cancer risk factors. RESULTS HIV positivity was associated with an increased risk of penile cancer, with adjusted hazard ratios of 2.63 (95% CI 1.64-4.23) when adjusting for age, race/ethnicity, baseline BMI, smoking and alcohol use, economic means test, and history of condyloma. The risk increased to hazard ratio = 4.25 (95% CI 2.75-6.57) when adjusting for all factors except history of condyloma. Risk factors for penile cancer in VWH included lower nadir CD4 + count, less than 50% of follow-up time with undetectable HIV viral load, and history of condyloma. CONCLUSION VWH - particularly those with low CD4 + counts, detectable HIV viral loads, or history of condyloma - are at increased risk of penile cancer, suggesting the penile cancer prevention activities are needed in this population.

Abstract
Contrasting ethical and legal arguments have been made concerning neonatal male circumcision (NMC) that merit the first systematic review on this topic. We performed PRISMA-compliant keyword searches of PubMed, EMBASE, SCOPUS, LexisNexis, and other databases and identified 61 articles that met the inclusion criteria. In the bibliographies of these articles, we identified 58 more relevant articles and 28 internet items. We found high-quality evidence that NMC is a low-risk procedure that provides immediate and lifetime medical and health benefits and only rarely leads to later adverse effects on sexual function or pleasure. Given this evidence, we conclude that discouraging or denying NMC is unethical from the perspective of the United Nations Convention on the Rights of the Child, which emphasizes the right to health. Further, case law supports the legality of NMC. We found, conversely, that the ethical arguments against NMC rely on distortions of the medical evidence. Thus, NMC, by experienced operators using available safety precautions, appears to be both legal and ethical. Consistent with this conclusion, all of the evidence-based pediatric policies that we reviewed describe NMC as low-risk and beneficial to public health. We calculated that a reduction in NMC in the United States from 80% to 10% would substantially increase the cases of adverse medical conditions. The present findings thus support the evidence-based NMC policy statements and are inconsistent with the non-evidence-based policies that discourage NMC. On balance, the arguments and evidence reviewed here indicate that NMC is a medically beneficial and ethical public health intervention early in life because it reduces suffering, deaths, cases, and costs of treating adverse medical conditions throughout the lifetimes of circumcised individuals.

Comments by opponents on the British Medical Association's guidance on non-therapeutic male circumcision of children seem one-sided and may undermine public health. World J Clin Pediatr 2023; 12:244-262. [PMID: 38178933 PMCID: PMC10762604 DOI: 10.5409/wjcp.v12.i5.244] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Download PDF] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 06/30/2023] [Revised: 09/07/2023] [Accepted: 09/25/2023] [Indexed: 12/08/2023] Open
Abstract
The British Medical Association (BMA) guidance on non-therapeutic circumcision (NTMC) of male children is limited to ethical, legal and religious issues. Here we evaluate criticisms of the BMA's guidance by Lempert et al. While their arguments promoting autonomy and consent might be superficially appealing, their claim of high procedural risks and negligible benefits seem one-sided and contrast with high quality evidence of low risk and lifelong benefits. Extensive literature reviews by the American Academy of Pediatrics and the United States Centers for Disease Control and Prevention in developing evidence-based policies, as well as risk-benefit analyses, have found that the medical benefits of infant NTMC greatly exceed the risks, and there is no reduction in sexual function and pleasure. The BMA's failure to consider the medical benefits of early childhood NTMC may partly explain why this prophylactic intervention is discouraged in the United Kingdom. The consequence is higher prevalence of preventable infections, adverse medical conditions, suffering and net costs to the UK's National Health Service for treatment of these. Many of the issues and contradictions in the BMA guidance identified by Lempert et al stem from the BMA's guidance not being sufficiently evidence-based. Indeed, that document called for a review by others of the medical issues surrounding NTMC. While societal factors apply, ultimately, NTMC can only be justified rationally on scientific, evidence-based grounds. Parents are entitled to an accurate presentation of the medical evidence so that they can make an informed decision. Their decision either for or against NTMC should then be respected.

Abstract
BACKGROUND Penile cancer accounts for less than 1% of male cancers in the United States. Localized disease, particularly T1 tumors are potentially curable with local therapy. We present the racial differences in survival outcomes for T1, penile cancer from the SEER database. METHODS From 2004 to 2016 all men with T1, N0, M0 penile cancer in the SEER-18 database were included. Kaplan-Meier analysis and multivariable Cox-Regression analysis were conducted to investigate prognostic variables for cancer specific survival (CSS). RESULTS A total of 4,406 men were identified with penile cancer; 1,941 men had T1 disease. The Kaplan-Meier (KM) analysis showed those with primary site surgery had better 5-year CSS compared to those without primary site surgery (P <.0001) and a significant difference in CSS based on race (P= 0.0078). On multivariable analysis, Hispanic individuals had worse CSS (HR 1.92; P = 0.0057) compared to the White men. Black men were also found to have a poor CSS however this was not statistically significant (HR 1.53, P = 0.118). Men with penile cancer who had either penectomy (HR 0.45; P = 0.006) or penile preservation surgery (HR 0.25; P< 0.001) had improved CSS. CONCLUSION Racial disparities in CSS exist among men with in early-stage penile cancer. KM analysis showed significant differences in CSS by race and in those receiving primary site surgery. On multivariable analysis, the CSS is worse in Hispanic compared to White men. There is a trend towards worse CSS in Black men however this was not statistically significant.

Abstract
OBJECTIVE To compare the differences and outcomes of surgical procedures, clinical effect, complications and patients' satisfaction between disposable oval-shaped circumcision device (Modified Chinese ShangRing series, Kiddie love®) and conventional circumcision in the treatment of children with phimosis or redundant prepuce. METHODS The clinical data were retrospectively analyzed in 114 children with phimosis or redundant foreskin undergone circumcision using a disposable oval-shaped circumcision device, a modified Chinese ShangRing series, Kiddie Love® (Kiddie Love group) in our hospital between January 2018 and February 2020, and another 114 children with similar conditions circumcised by conventional surgical procedure before January 2018 (conventional group). The two groups were compared regarding the operative time, intraoperative blood loss, postoperative pain scores, healing time, the incidence of complications and guardian's satisfaction. RESULTS Circumcision was successfully completed in children in both groups. The operative time, intraoperative blood loss, postoperative pain scoring in 24 h by VAS, pain at the removal of the device or stitches and wound healing were (6.4 ± 1.6) min, (34.1 ± 6.4) min; (0.7 ± 0.2) ml, (2.6 ± 0.6) ml; (2.2 ± 1.0) points, (1.3 ± 0.5) points; (23.7 ± 3.9)day, (15.9 ± 2.8)day, respectively for Kiddie Love group and conventional group(either P < 0.05 or P > 0.05). The two groups were significantly different in the incidence of hematoma, edema and incision dehiscenceyet were insignificant in incision infection. Children in both groups were followed up from 6 to 31 months (mean: 23 months), and the satisfaction rate was 94.7% (108/114) in parents of the children circumcised by the ShangRing and 83.3% (95/114) in those of children treated by conventional circumcision (P < 0.05). CONCLUSION Modified Chinese ShangRing, Kiddie Love®, has superiorities, including simpler procedure, shorter operative time, less blood loss, fewer complications, better cosmetic results and higher satisfaction of patients over conventional circumcision in the treatment of children with phimosis or redundant foreskin, and worthy of wider clinical recommendation.

Abstract
The removal of non-pathogenic foreskin from the penis of healthy neonates and infants for non-religious reasons is routinely practiced in many parts of the world. High level data from well-designed randomized controlled trials of circumcision in neonates and infants does not guide clinical practice. Reliable counts of immediate and short term circumcision complications are difficult to estimate. Emerging evidence suggests routine neonatal circumcision could lead to long term psychological, physical, and sexual complications in some men. The stigma associated with discussing circumcision complications creates a prevalence paradox where the presence of significant circumcision complications is higher than reported. Prior to the Internet, there were very few forums for men from diverse communities, who were troubled about their circumcision status, to discuss and compare stories. To investigate the long term consequences of circumcision, we reviewed 135 posts from 109 individual users participating in a circumcision grief subsection of Reddit, an internet discussion board. We identified three major categories of complications: physical such as pain during erections and lost sensitivity, psychological such as anxiety and violation of autonomy, and sexual such as feeling that the sexual experience was negatively altered or being unable to complete a sexual experience. We also identified a "discovery process" where some men described coming into awareness of their circumcision status. These findings suggest that neonatal circumcision can have significant adverse consequences for adult men. The removal of normal foreskin tissue should be limited to adult men who choose the procedure for cosmetic reasons or when medically indicated.

Abstract
BackgroundTo determine the association between tumor location and both clinicopathological characteristics and the survival of patients with M0 squamous cell carcinoma of the penis (SCCP).MethodsData of 455 patients diagnosed with M0 SCCP between 1975 and 2018 were collected from the Surveillance, Epidemiology, and End Results (SEER) database of the United States National Cancer Institute. The effects of tumor location on overall survival (OS) and penile carcinoma-specific survival (PCSS) were analyzed using the Kaplan–Meier method. The Cox proportional hazards regression model was used to determine the impact of tumor location on PCSS.ResultsSCCP was more likely to occur in the prepuce or glans (90%). Although no significant difference was observed between the OS of patients with M0 SCCP in the prepuce or glans and those with M0 SCCP in the body of the penis (p = 0.307), the former had better PCSS (p = 0.024). Moreover, M0 SCCP in the prepuce or glans was also significantly associated with better PCSS in patients with advanced age (age ≥ 60 years, p = 0.011), other ethnicities (p = 0.003), T2–T4 stage (p = 0.036), larger tumors (≥3 cm, p = 0.001), no regional lymph nodes removed (p = 0.044), and radical surgery (p = 0.027). Multivariate analysis confirmed that tumor location is an independent prognostic factor for patients with M0 SCCP [hazard ratio (HR) 1.881, p = 0.026].ConclusionsTumor location is an independent prognostic factor for patients with M0 SCCP, and tumors in the prepuce or glans portend better PCSS.

Abstract
Although relatively rare in the United States, penile squamous cell carcinoma is encountered worldwide at a higher rate. Initial diagnosis is often made on clinical exam, as almost all of these lesions are externally visible and amenable to biopsy. In distinction to other types of malignancies, penile cancer relies heavily on clinical nodal staging of the inguinal lymph node chains. As with all cancers, imaging plays a role in the initial staging, restaging, and surveillance of these patients. The aim of this manuscript is to highlight the applications, advantages, and limitations of different imaging modalities in the evaluation of penile cancer, including ultrasound, computed tomography, magnetic resonance imaging, and positron emission tomography.

BACKGROUND Circumcision has been one of the most commonly performed surgical procedures worldwide since ancient times. Given the popularity of this procedure, the aim of this study was to evaluate the effectiveness, reliability, and results of circumcision performed using the NeoAlis™ clamp and compare them with those obtained using the sleeve technique. STUDY DESIGN The results of 2259 patients circumcised using the two techniques were evaluated retrospectively. The patients who were circumcised using the plastic NeoAlis™ device were classified as group 1 and those circumcised using the sleeve technique were designated as group 2. The groups were compared in terms of operation time, results, cost, complications, and cosmetic satisfaction scores. RESULTS A total of 1947 patients who met the inclusion criteria were included in the study. Group 1 consisted of 1454 patients, while group 2 comprised 493 patients. The total rate of complications, excluding bleeding in the form of oozing that stopped spontaneously, was 9.5% (n = 185). In group 1, the operation time was shorter, tolerability of local anesthesia was higher, satisfaction questionnaire scores were higher, cost was lower, and rates of early adhesion and meatal stenosis were lower. All of these parameters were significantly different from those in group 2. Notably, secondary phimosis was significantly higher in group 1. Although the bleeding that stopped with follow-up was significantly higher in group 2, there was no significant difference between the groups in terms of bleeding that required surgical intervention. DISCUSSION Our study, which reports the results of circumcisions performed using the NeoAlis clamp, has the largest sample size in the literature. Moreover, this is the only study in the literature wherein the results of sleeve circumcision, which is a time-tested surgical procedure, and the results of NeoAlis clamp circumcision, which we applied to a large number of patients, were compared with each other and with the literature. The retrospective design that focused on relatively short-term (one month) results is the major limitation of this study. CONCLUSION Mass circumcision performed with a plastic clamp technique is safe, timesaving, easily teachable, and cosmetically advantageous.

Prevalence and genotype distribution of human papillomavirus infection in different anatomical sites among men who have sex with men: A systematic review and meta-analysis. Rev Med Virol 2021; 31:e2219. [PMID: 33527636 DOI: 10.1002/rmv.2219] [Citation(s) in RCA: 18] [Impact Index Per Article: 4.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/22/2020] [Revised: 01/07/2021] [Accepted: 01/12/2021] [Indexed: 12/15/2022]
Abstract
Men who have sex with men (MSM) are at increased risk of human papillomavirus (HPV) infection because of their high-risk sexual behaviours. In this study, a meta-analytic approach was used to systematically analyse the literature to elucidate the prevalence and genotype distribution of anal, penile, oral and urethral HPV infection among MSM in the world. To carry out this systematic review, five electronic databases including Web of Science, PubMed, Scopus, Embase, and Google Scholar were searched for relevant studies published from January 2012 to November 2019, and pertinent data were collected from the eligible articles. The pooled HPV prevalence was calculated for each anatomical region using a random-effect model weighted by the inverse variance method. The meta-analysis was performed using the "Metaprop" function in the R package Meta. The overall pooled prevalence of anal, penile, oral and urethral HPV infection among MSM were 78.4% (95% confidence interval [CI]: 75.6%-81.0%), 36.2% (95% CI: 29.1%-44.0%), 17.3% (95% CI: 13.6%-21.7%) and 15.4% (95% CI: 7.8%-27.9%), respectively. Stratified analyses showed that the prevalences of HPV were significantly higher in HIV-positive than HIV-negative MSM. The most frequent HPV high-risk type detected in the anus, penis and oral cavity was HPV-16 (19.9%, 4.9% and 3.1%, respectively). HPV infection is rising in MSM because of high-risk sexual behaviours, suggesting an increased future risk of developing HPV-related diseases and malignancies in this population.

Abstract
Penile cancer is a rare malignancy with a reported incidence of 0.66–1.44 per 100,000 men, and a reported mortality of 0.15–0.37 per 10,000 men. Expert clinical examination and histological diagnosis from biopsy is required to determine the extent and invasion of disease, which is paramount in planning of appropriate treatment. Management of loco-regional penile cancer can be divided into management of primary tumour and management of regional lymph nodes. This review article will focus on the management of the primary penile tumour with particular focus on penile sparing therapies. The aim of primary penile tumour management is to completely remove the tumour whilst preserving as much organ function as possible. Preservation of the penis is important as it allows patients to maintain urinary and sexual function, as well as quality of life. With the majority of penile cancer confined to the glans and foreskin, most penile cancers can be managed with organ-preserving therapy. A wide variety of treatment options are available, and this review aims to describe each of the options including the reported oncological and functional outcome for the different therapies for penile cancer.

Abstract
Penile cancers are rare malignancies. Traditional surgical options, including partial and total penectomy, can dramatically affect a patient's quality of life and mental health. In select patients, penile sparing techniques (PST) have the potential to remove the primary tumor with comparable oncologic outcomes while maintaining penile length, sexual function, and urinary function. In this review, we aim to discuss the indications, advantages, and outcomes of the various PST currently available for men seeking an organ-preserving option for their penile cancer.

Abstract
INTRODUCTION Perioperative management of children with haemophilia undergoing surgery is a complex and understudied topic. Circumcision is the most common procedure performed in the neonatal period, and guidelines to prevent bleeding complications from circumcision are lacking. Treatment protocols vary widely, and many centres treat patients with factor products for up to two weeks after circumcision. There is an unmet need for studies evaluating optimal factor replacement therapy around the time of circumcision in neonates with severe haemophilia. AIM To determine the efficacy of a single dose of factor replacement before circumcision to prevent bleeding complications in neonates with severe haemophilia. METHODS We conducted a retrospective chart review of male infants born between January 2000 and June 2019. Male neonates with severe haemophilia diagnosed at the Iowa Hemophilia and Thrombosis Center (n = 22) and healthy newborn controls who underwent circumcision at the University of Iowa Hospitals were included. Data were collected from the electronic medical record. Neonates with severe haemophilia were separated into two groups-those pretreated with one dose of factor replacement before circumcision and those without pretreatment. RESULTS We observed that neonates with severe haemophilia pretreated with a single dose of factor VIII or factor IX replacement had significantly reduced bleeding complications, shorter hospital stay and required less therapeutic intervention compared with untreated patients. Importantly, pretreated patients had outcomes similar to healthy controls. CONCLUSIONS Our results demonstrate that a single dose of factor replacement before circumcision is effective to prevent bleeding in neonates with severe haemophilia.

Abstract
OBJECTIVES To determine caregiver-reported reasons for delay of desired neonatal circumcision. METHODS Caregivers requesting elective outpatient circumcision at two urban tertiary care hospitals were surveyed from 1/2017 to 12/2018. Boys >3 years and those with abnormal penile anatomy were excluded. Patient/parent demographics, insurance status, comorbidities, birth history, family history, reasons circumcision was desired, and reasons for circumcision delay were obtained. RESULTS Surveys were completed by 206/229 caregivers (90% response rate). Respondents were primarily mothers (74%) who identified as African-American (62%). Eligible boys presented at a median 7.5 months [0.3-35.6] and were predominantly African-American (63%), publicly-insured at birth (83%), and publicly-insured at present (86%). 80% were full-term. 83% had no comorbidities. Most caregivers (84%) requested inpatient circumcision, primarily for penile cleanliness (75%) and infection prevention (72%). Common reasons for delay included neonatal circumcision not being performed by the birth physician/hospital (26%) and prematurity (16%). Publicly-insured boys were more likely to encounter delays related birth physician/hospital not performing circumcisions (P = .02). Non-Caucasian/mixed race boys were less likely to be eligible for circumcision without general anesthesia (P = .004). In 108 cases (52%), circumcision was requested for full-term boys without comorbidities. Of these, 72 (35% of the cohort) now require general anesthesia to undergo circumcision. CONCLUSION Among 206 boys experiencing circumcision delay, most were full-term, African-American, and publicly-insured. Common reasons for delay included neonatal circumcision not being performed by the birth hospital/physician and prematurity. General anesthesia could have been avoided in >35% of boys if circumcision was performed at birth.

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
Purpose: We aimed to reveal the effects of marital status on survival outcomes in patients with penile cancer. Methods: Patients with penile cancer who were diagnosed between 2004 and 2015 were identified by using the Surveillance, Epidemiology and End Results (SEER) database. Kaplan-Meier and Cox regressions were used to analyse the effects of marital status on overall survival (OS) and cancer-specific survival (CSS). Results: Among 3,195 eligible patients with penile cancer, 1,951 (61.1%) patients were married, 365 (11.4%) were divorced or separated, 327 (10.2%) were widowed and 552 (17.3%) were single. The widowed patients had the worst OS median survival time (22 months) and CSS median survival time (23.5 months). Marital status was an independent prognostic factor for OS and CSS of penile cancer patients. The multivariate Cox regression showed that widowed patients exhibited the poorest OS (hazard ratio [HR]: 1.73; 95% confidence interval [CI]: 1.48-2.03, p < 0.001) and the poorest CSS (HR: 1.64; 95% CI: 1.144-1.279, p < 0.001) compared with married patients. Similar results were observed in our centre database and the subgroup analyses based on the SEER stage and grade. Conclusions: In our study, we found that marital status was an independent prognostic factor for survival in patients with penile cancer. Additionally, widowed patients had the lowest OS and CSS compared with married patients.

Abstract
BACKGROUND Circumcision is widely accepted for newborns in the United States. However, circumcision carries a risk of complications, the rates of which are not well described in the contemporary era. METHODS We performed a longitudinal population analysis of the California Office of Statewide Health Planning and Development database between 2005 and 2010. Using International Classification of Procedures, Ninth Revision, Clinical Modification and Current Procedural Terminology codes, we calculated early and late complication rates by Kaplan-Meier survival estimates. Late complications were defined as those that occurred between 30 d and 5 y after circumcision. Descriptive analysis of complications was obtained by analysis of variance, chi-square test, or log-rank test. On adjusted analysis, a Cox proportional hazard model was performed to determine the risk of early and late complications, adjusting for patient demographics. RESULTS A total of 24,432 circumcised children under age 5 y were analyzed. Overall, cumulative complication rates over 5 y were 1.5% in neonates, 0.5% of which were early, and 2.9% in non-neonates, 2.2% of which were early. On adjusted analysis, non-neonates had a higher risk of early complications (OR 18.5). In both neonates and non-neonates, the majority of patients with late complications underwent circumcision revision. CONCLUSIONS Circumcision has a complication rate higher than previously recognized. Most patients with late complications after circumcision received an operative circumcision revision. Clinicians should weigh the surgical risks against the reported medical benefits of circumcision when counseling parents about circumcision.

Abstract
Background: Previous Brazilian studies have indicated that working in agriculture could lead to an increased risk of penile cancer. The present descriptive study aimed at establishing a possible association between penile cancer and agricultural occupation. Materials and methods: Data on a total of 103 penile cancer patients were obtained from medical records of two reference centres for cancer treatment in the state of Paraíba, Northeast Brazil. Information about sexual behaviour was obtained in interviews for 48 cases. Results: Of 103 patients 38 and 52 were illiterate and had not completed graduation, respectively, and 60 earned less than twice the minimum wage. All together, 72 (70%) worked in agriculture and 39 confirmed involvement in application of agrochemicals. A history of phimosis was noted for 42 (69%) out of 61 patients and 40 (59%) out of 68 ever smoked. Pathological signs of HPV infection were detected in 45 (70%) out of 64 patients. Of the 48 interviewed patients, 27 (56%) confirmed sexual contact with prostitutes and eight (19%) out of 43 had sex with animals. Conclusions: Data confirmed the presence of several risk factors for penile cancer, like phimosis, smoking, HPV infection and promiscuous sexual behaviour. The high number of Brazilian agricultural workers with penile cancer was unexpected if compared with other professional groups. Future studies should focus on this group of men and elucidate possible reasons for their increased risk.

Abstract
BACKGROUND Male circumcision reduces men's risk of acquiring HIV and some sexually transmitted infections from heterosexual exposure, and is essential for HIV prevention in sub-Saharan Africa. Studies have also investigated associations between male circumcision and risk of acquisition of HIV and sexually transmitted infections in women. We aimed to review all evidence on associations between male circumcision and women's health outcomes to benefit women's health programmes. METHODS In this systematic review we searched for peer-reviewed and grey literature publications reporting associations between male circumcision and women's health outcomes up to April 11, 2016. All biomedical (not psychological or social) outcomes in all study types were included. Searches were not restricted by year of publication, or to sub-Saharan Africa. Publications without primary data and not in English were excluded. We extracted data and assessed evidence on each outcome as high, medium, or low consistency on the basis of agreement between publications; outcomes found in fewer than three publications were indeterminate consistency. FINDINGS 60 publications were included in our assessment. High-consistency evidence was found for five outcomes, with male circumcision protecting against cervical cancer, cervical dysplasia, herpes simplex virus type 2, chlamydia, and syphilis. Medium-consistency evidence was found for male circumcision protecting against human papillomavirus and low-risk human papillomavirus. Although the evidence shows a protective association with HIV, it was categorised as low consistency, because one trial showed an increased risk to female partners of HIV-infected men resuming sex early after male circumcision. Seven outcomes including HIV had low-consistency evidence and six were indeterminate. INTERPRETATION Scale-up of male circumcision in sub-Saharan Africa has public health implications for several outcomes in women. Evidence that female partners are at decreased risk of several diseases is highly consistent. Synergies between male circumcision and women's health programmes should be explored.

Abstract
Objectives The aim of this study is to report an unusual form of penile cancer presentation associated with myiasis infestation, treatment options and outcomes. Materials and Methods We studied 10 patients with suspected malignant neoplasm of the penis associated with genital myiasis infestation. Diagnostic assessment was conducted through clinical history, physical examination, penile biopsy, larvae identification and computerized tomography scan of the chest, abdomen and pelvis. Clinical and pathological staging was done according to 2002 TNM classification system. Radical inguinal lymphadenectomy was conducted according to the primary penile tumor pathology and clinical lymph nodes status. Results Patients age ranged from 41 to 77 years (mean=62.4). All patients presented squamous cell carcinoma of the penis in association with myiasis infestation caused by Psychoda albipennis. Tumor size ranged from 4cm to 12cm (mean=5.3). Circumcision was conducted in 1 (10%) patient, while penile partial penectomy was performed in 5 (50%). Total penectomy was conducted in 2 (20%) patients, while emasculation was the treatment option for 2 (20%). All patients underwent radical inguinal lymphadenectomy. Prophylactic lymphadenectomy was performed on 3 (30%) patients, therapeutic on 5 (50%), and palliative lymphadenectomy on 2 (20%) patients. Time elapsed from primary tumor treatment to radical inguinal lymphadenectomy was 2 to 6 weeks. The mean follow-up was 34.3 months. Conclusion The occurrence of myiasis in the genitalia is more common in patients with precarious hygienic practices and low socio-economic level. The treatment option varied according to the primary tumor presentation and clinical lymph node status.

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
The objective of this study was to determine whether the justifications given for promoting mass circumcision as a preventive measure for HIV infection are reasonable and whether mass circumcision is a feasible preventive measure for HIV infection in developing countries. The medical literature concerning the practice of circumcision in the absence of medical indication was reviewed regarding its impact on HIV infection and related issues. The literature was analysed with careful attention to historical perspective. Our results show that the medical literature supporting mass circumcision for the prevention of HIV infection is inconsistent and based on observation studies. Even if the two ongoing randomised controlled trials in Africa show a protective benefit of circumcision, factors such as the unknown complication rate of the procedure, the permanent injury to the penis, human rights violations and the potential for veiled colonialism need to be taken into account. Based on the best estimates, mass circumcision would not be as cost-effective as other interventions that have been demonstrated to be effective. Even if effective, mass circumcision as a preventive measure for HIV in developed countries is difficult to justify.

Abstract
OBJECTIVE To evaluate insulin-like growth factor-1 receptor (IGF1R) expression in penile cancer and its association with oncologic outcomes. METHODS Tissue microarrays were constructed from 53 patients treated at our institution. Expression of IGF1R was evaluated using a Her2-like scoring system. Overexpression was defined as 1+ or greater membranous staining. Association of IGF1R expression with pathologic features was assessed with comparative statistics, and association with local recurrence, progression to nodal or distance metastases, or death was assessed with Kaplan-Meier survival analysis and Cox proportional hazard regression models. RESULTS Overall, IGF1R overexpression was seen in 33 (62%) cases. With a median follow-up of 27.8 months, IGF1R overexpression was associated with inferior progression-free survival (PFS) (P = .003). In a multivariable model controlling for grade, T stage, perineural invasion, and lymphovascular invasion, IGF1R expression was independently associated with disease progression (hazard ratio 2.3, 95% confidence interval 1.1-5.1, P = .03. Comparing patients without IGF1R overexpression to those with overexpression, 5-year PFS was 94.1% vs 45.8%. CONCLUSION IGF1R overexpression was associated with inferior PFS in penile cancer. Drugs that target IGF1R and downstream messengers may have a therapeutic benefit in patients that exhibit IGF1R overexpression.

Abstract
OBJECTIVE Circumcision, by most conventional methodologies, involves division of the frenulum and excision of the entire foreskin covering the glans. This seemingly simple procedure is occasionally associated with dreadful and devastating complications. We describe a new frenulum-sparing technique that circumvents some of the potential complications of conventional techniques and could also potentially help preserve preputial role in sexual function. MATERIALS AND METHODS An initial dorsal slit, three fourths of the way up to the corona is extended laterally and obliquely on either side, to meet the preputial edge, 3-4 mm from the frenulum. A broad sleeve of sub-coronal mucosa is thus preserved. The frenulum is left untouched, leaving a wide skin bridge connecting the mucosal sleeve with the shaft skin. The raw area is closed with interrupted, synthetic absorbable sutures. Over a three year period, 42 patients were circumcised using this technique. RESULTS No significant complications like frenular bleed, painful postoperative erections, chordee, meatal stenosis, or urethra-cutaneous fistula were observed in any patient. The cosmetic results were pleasing. CONCLUSION The frenulum-sparing technique of circumcision is a promising modification to the various existing techniques. The method described is technically easier to perform than conventional frenulum-dividing procedures and has an acceptable cosmesis. Further randomised controlled studies on larger cohorts are necessary to establish the true benefits of this technique over established procedures.

Abstract
BACKGROUND Premature ejaculation is one of the prevalent disorders in men; almost one out of three men between 18 and 59 years old have this disorder with its leading sequel such as lack of self-confidence, anxiety, depression and unsatisfactory intercourse in men and their partners. This study aimed to compare the length of penile mucosa in men with and without premature ejaculation. METHOD Three hundred and eighty patients referring to our hospital from March 2009 to March 2010 were enrolled in the study. First group comprised 190 men with premature ejaculation and second group included 190 men without premature ejaculation as control group that were chosen randomly. A questionnaire was designed to collect data and was completed for both groups. Height, weight, body mass index (BMI), length of penile mucosa, length of penis and intravaginal ejaculation latency time (IELT) were measured. RESULTS The mean IELT in premature ejaculation group and control group were 47.58 ± 29.55 and 410.38 ± 190.2 s, respectively (p = 0.001). The mean penis length in premature ejaculation group and control group were 127.25 ± 16.23 and 127.03 ± 17.42 mm, respectively (p = 0.901, with nonsignificant difference); the mean penile mucosa in premature ejaculation group was 33.83 ± 11.54 mm and in control group was 31.40 ± 11.97 mm (p = 0.014, with significant difference). CONCLUSION Longer penile mucosa can be one of the factors in causing premature ejaculation.

Abstract
Purpose To investigate and compare the trends in incidence and mortality of penile cancer between Australia, England and Wales, and the US, and provide hypotheses for these trends. Methods Cancer registry data from 1982 to 2005 inclusive were obtained from Australia, England and Wales, and the United States. From these data, age-specific, -standardised and mortality:incidence ratios were calculated, and compared. Results The overall incidence of penile cancer in England and Wales (1.44 per 100,000 man-years) was higher than in Australia (0.80 per 100,000), and the US (0.66 per 100,000). Incidence of penile cancer in all three countries has remained relatively stable over time. Similarly, although the mortality rates were also higher in England and Wales (0.37 per 100,000 man-years) compared to Australia (0.18 per 100,000) and the US (0.15 per 100,000), the mortality/incidence ratios were similar for all three countries. Conclusions Penile cancer incidence is low, affecting mainly older men. Rates differ between the three countries, being twice as common in England and Wales as in the other studied regions. Circumcision rates have a potential influence on these rates but are not the sole explanation for the variation.

Abstract
BACKGROUND Despite penile carcinoma (PeCa) being a relatively rare neoplasm, it remains an important public health issue for poor and developing countries. Contrary to most tumors, limited data are available for markers that are capable of assisting in diagnosis, prognosis, and treatment of PeCa. We aimed to identify molecular markers for PeCa by evaluating their epigenomic and transcriptome profiles and comparing them with surrounding non-malignant tissue (SNT) and normal glans (NG). RESULTS Genome-wide methylation analysis revealed 171 hypermethylated probes in PeCa. Transcriptome profiling presented 2,883 underexpressed and 1,378 overexpressed genes. Integrative analysis revealed a panel of 54 genes with an inverse correlation between methylation and gene expression levels. Distinct methylome and transcriptome patterns were found for human papillomavirus (HPV)-positive (38.6%) and negative tumors. Interestingly, grade 3 tumors showed a distinct methylation profile when compared to grade 1. In addition, univariate analysis revealed that low BDNF methylation was associated with lymph node metastasis and shorter disease-free survival. CpG hypermethylation and gene underexpression were confirmed for a panel of genes, including TWIST1, RSOP2, SOX3, SOX17, PROM1, OTX2, HOXA3, and MEIS1. CONCLUSIONS A unique methylome signature was found for PeCa compared to SNT, with aberrant DNA methylation appearing to modulate the expression of specific genes. This study describes new pathways with the potential to regulate penile carcinogenesis, including stem cell regulatory pathways and markers associated to a worse prognosis. These findings may be instrumental in the discovery and application of new genetic and epigenetic biomarkers in PeCa.

Abstract
Background Penile cancer is an uncommon malignancy in developed countries, but the incidence is as high as 10% to 20% of all male cancers in some developing countries. There is a paucity of published data on this subject in our setting. This study describes the clinicopathological presentation and treatment outcome of this condition in our environment, and highlights challenges associated with the care of these patients and proffers solutions for improved outcome. Methods This was a retrospective study of histologically confirmed cases of penile cancer seen at Bugando Medical Centre between January 2004 and December 2013. Results There were 236 penile cancer patients representing 2.2% of all male malignancies during the study period. The median age was 47 years with a modal age group of 41 to 50 years. Of the 236 patients, 147 (62.3%) had severe phimosis. The majority of patients (89.8%) were uncircumcised. A history of human papilloma virus (HPV) was reported in 12 (5.1%) cases. One hundred eighty-two (77.1%) patients reported history of cigarette smoking. Seven (6.7%) patients were human immunodeficiency virus (HIV) positive. The majority of the patients (68.6%) presented with Jackson’s stages III and IV. Squamous cell carcinoma was the most common histopathological type (99.2%). Lymph node metastasis was recorded in 65.3% of cases, and it was significantly associated with the tumor size, histopathological subtype, histopathological grade, lympho-vascular invasion, positive resection margins, and urethral involvement (P < 0.001). Distant metastasis accounted for 4.2% of cases. The majority of patients (63.1%) underwent partial penectomy. Chemotherapy and radiotherapy were given in 14 (5.9%) and 12 (5.1%) patients, respectively. Complication and mortality rates were 22.0% and 4.2%, respectively. HIV positivity, histopathological stage and grade of the tumor, and presence of metastases at the time of diagnosis were the main predictors of death (P < 0.001). The median length of hospitalization was 14 days. Local recurrence was reported in 12 (5.3%) patients. Data on long-term survivals were not available as the majority of patients were lost to follow-up. Conclusions Penile cancer is not rare in our environment. The majority of patients present late with advanced stage of the disease. Early detection of primary cancer at an early stage may improve the prognosis.

Abstract
BACKGROUND AND OBJECTIVES The emerging science demonstrates various health benefits associated with infant male circumcision and adult male circumcision; yet rates are declining in the United States. The American Academy of Pediatrics and the Centers for Disease Control and Prevention recommend that healthcare providers present evidence-based risk and benefit information for infant male circumcision to parent(s) and guardian(s). The purpose of this study was to assess providers' level of infant male circumcision knowledge and to identify the associated characteristics. METHODS An online survey was administered to healthcare providers in the family medicine, obstetrics, and pediatrics medical specialties at an urban academic health center. To assess infant male circumcision knowledge, a 17 point summary score was constructed to identify level of provider knowledge within the survey. RESULTS Ninety-two providers completed the survey. Providers scored high for the following knowledge items: adverse event rates, protects against phimosis and urinary tract infections, and does not prevent hypospadias. Providers scored lower for items related to more recent research: protection against cervical cancer, genital ulcer disease, bacterial vaginosis, and reduction in HIV acquisition. Two models were constructed looking at (1) overall knowledge about male circumcision, and (2) knowledge about male circumcision reduction in HIV acquisition. Pediatricians demonstrated greater overall infant male circumcision knowledge, while obstetricians exhibited significantly greater knowledge for the HIV acquisition item. CONCLUSION Providers' knowledge levels regarding the risks and benefits of infant male circumcision are highly variable, indicating the need for system-based educational interventions.

Abstract
Abnormalities of the external genitalia span the spectrum from subtle findings of limited clinical significance to profound anomalies that call into question such essential questions as sex determination. In addition, missing a diagnosis of congenital adrenal hyperplasia in a newborn female child with virilized external genitalia can result in near-term mortality, whereas a large inguinal hernia could present rapidly with incarceration if undetected. To that end, this article seeks to present a survey of commonly encountered genital abnormalities while highlighting those scenarios that require multidisciplinary interventions.

Abstract
INTRODUCTION In 2012, the American Academy of Pediatrics (AAP) and the American Congress of Obstetricians and Gynecologists (ACOG) published recommendations that physicians should discuss with parents the benefits and risks of newborn male circumcision. Our objective was to assess physicians' perspectives of newborn male circumcision. METHODS A self-administered, cross-sectional electronic survey of US physicians was conducted in 2008 (N = 1500). RESULTS Approximately one-third (33.2%) of the respondents reported that their current perspective was that the medical benefits outweigh the risks associated with newborn male circumcision and less than one-third (31.1%) reported they would recommend the procedure when counseling parents. CONCLUSIONS In 2008, only about one-third of the physicians surveyed thought that the benefits of male circumcision outweighed the risks and recommended it to parents of newborn sons. These attitudes may be relevant to the declining circumcision rates in the United States. Repeat surveys may be useful, given the new AAP and ACOG recommendations.

Abstract
Randomized trials have demonstrated that male circumcision (MC) reduces heterosexual acquisition of HIV, herpes simplex virus type 2, human papillomavirus (HPV), and genital ulcer disease among men, and it reduces HPV, genital ulcer disease, bacterial vaginosis, and trichomoniasis among female partners. The pathophysiology behind these effects is multifactorial, relying on anatomic and cellular changes. MC is cost effective and potentially cost saving in both the United States and Africa. The World Health Organization and Joint United Nations Program on HIV/AIDS proposed reaching 80% MC coverage in HIV endemic countries, but current rates fall far behind targets. Barriers to scale-up include supply-side and demand-side challenges. In the United States, neonatal MC rates are decreasing, but the American Academy of Pediatrics now recognizes the medical benefits of MC and supports insurance coverage. Although MC is a globally valuable tool to prevent HIV and other sexually transmitted infections, it is underutilized. Further research is needed to address barriers to MC uptake.

Abstract
Penile carcinoma (PeCa) represents an important public health problem in poor and developing countries. Despite its unpredictable behavior and aggressive treatment, there have only been a few reports regarding its molecular data, especially epigenetic mechanisms. The functional diversity in different cell types is acquired by chromatin modifications, which are established by epigenetic regulatory mechanisms involving DNA methylation, histone acetylation, and miRNAs. Recent evidence indicates that the dysregulation in these processes can result in the development of several diseases, including cancer. Epigenetic alterations, such as the methylation of CpGs islands, may reveal candidates for the development of specific markers for cancer detection, diagnosis and prognosis. There are a few reports on the epigenetic alterations in PeCa, and most of these studies have only focused on alterations in specific genes in a limited number of cases. This review aims to provide an overview of the current knowledge of the epigenetic alterations in PeCa and the promising results in this field. The identification of epigenetically altered genes in PeCa is an important step in understanding the mechanisms involved in this unexplored disease.

Abstract
A potential impediment to evidence-based policy development on medical male circumcision (MC) for HIV prevention in all countries worldwide is the uncritical acceptance by some of arguments used by opponents of this procedure. Here we evaluate recent opinion-pieces of 13 individuals opposed to MC. We find that these statements misrepresent good studies, selectively cite references, some containing fallacious information, and draw erroneous conclusions. In marked contrast, the scientific evidence shows MC to be a simple, low-risk procedure with very little or no adverse long-term effect on sexual function, sensitivity, sensation during arousal or overall satisfaction. Unscientific arguments have been recently used to drive ballot measures aimed at banning MC of minors in the USA, eliminate insurance coverage for medical MC for low-income families, and threaten large fines and incarceration for health care providers. Medical MC is a preventative health measure akin to immunisation, given its protective effect against HIV infection, genital cancers and various other conditions. Protection afforded by neonatal MC against a diversity of common medical conditions starts in infancy with urinary tract infections and extends throughout life. Besides protection in adulthood against acquiring HIV, MC also reduces morbidity and mortality from multiple other sexually transmitted infections (STIs) and genital cancers in men and their female sexual partners. It is estimated that over their lifetime one-third of uncircumcised males will suffer at least one foreskin-related medical condition. The scientific evidence indicates that medical MC is safe and effective. Its favourable risk/benefit ratio and cost/benefit support the advantages of medical MC.

Abstract
Penile squamous cell carcinoma (SCC) is uncommon in Europe, where it accounts for approximately 0.7% of all malignant tumors in men. The main risk factors are poor hygiene, lack of circumcision, human papillomavirus (HPV) infection, and certain chronic inflammatory skin diseases. HPV infection is detected in 70% to 100% of all penile in situ SCCs and in 30% to 50% of invasive forms of the disease, mainly basaloid and warty SCCs. In situ tumors can be treated conservatively, but close monitoring is essential as they become invasive in between 1% and 30% of cases. The treatment of choice for penile SCC is surgery. Inguinal lymph node irradiation is no longer recommended as a prophylactic measure, and it appears that selective lymph node biopsy might be useful for reducing the morbidity associated with prophylactic inguinal lymph node dissection. Survival is directly related to lymph node involvement. Improving our knowledge of underlying molecular changes and their associated genotypes will open up new therapeutic pathways.

Abstract
Heterosexual exposure accounts for most HIV transmission in sub-Saharan Africa, and this mode, as a proportion of new infections, is escalating globally. The scientific evidence accumulated over more than 20 years shows that among the strategies advocated during this period for HIV prevention, male circumcision is one of, if not, the most efficacious epidemiologically, as well as cost-wise. Despite this, and recommendation of the procedure by global policy makers, national implementation has been slow. Additionally, some are not convinced of the protective effect of male circumcision and there are also reports, unsupported by evidence, that non-sex-related drivers play a major role in HIV transmission in sub-Saharan Africa. Here, we provide a critical evaluation of the state of the current evidence for male circumcision in reducing HIV infection in light of established transmission drivers, provide an update on programmes now in place in this region, and explain why policies based on established scientific evidence should be prioritized. We conclude that the evidence supports the need to accelerate the implementation of medical male circumcision programmes for HIV prevention in generalized heterosexual epidemics, as well as in countering the growing heterosexual transmission in countries where HIV prevalence is presently low.

Abstract
The aim of this article is to describe the circumcision procedure during history, its therapeutic and preventive goals, with focus on bioethical, economic and law issues. The origins of this practice are lost in antiquity. It was performed since 3000 BC by the Egyptians for hygienic and religious reasons. Moreover, male circumcision is a religious commandment in Judaism and Islam, and it is customary in some Oriental Orthodox and other Christian churches of Africa. Nowadays, circumcision is performed as a routine procedure by the Jews and the Muslims for religious reasons. The world prevalence of men with circumcision is 12.5-33%, especially in USA, Canada, Islamic people and Africa; in Europe the prevalence rate is low (in Great Britain it is 1.5%). Currently, male circumcision is being highly debated because of ethical, law and scientific issues and the different roles of this procedure: therapeutic, prophylactic (but there is no universal consensus) and ritualistic role. Nowadays, in Italy there is a strong debate about the consensus for this practice and its indications. The Italian law does not allow performing ritualistic circumcision, as a free of charge procedure in public hospitals, at the government's expenses, because the Italian law must protect different religious cultures, in name of the laity of the State. Thus, national bioethical committee (CNB) has established that ritualistic circumcision may only be performed on a paying basis in public hospitals. As a protective practice, circumcision has decreased in the entire world because of the improvement of hygienical conditions and, above all, the lack of unanimous consent on the real usefulness of protective circumcision, even if several studies have recently demonstrated the protecting role of male circumcision against HIV infection.
