Association between male circumcision and women's biomedical health outcomes: a systematic review

Utilization of subcutaneous indwelling 2-0 silk thread for inner plate frenulum alignment in circumcision using a disposable circumcision suture device: A modified surgical technique

BACKGROUND

This prospective nonrandomized controlled study aimed to compare the surgical outcomes, postoperative complications, and patient experiences between a modified circumcision technique using a disposable circumcision suture device and the standard circumcision method using a disposable circumcision suture device in Chinese patients with excess foreskin or phimosis at our department of urology and andrology.

MATERIALS AND METHODS

A total of 456 patients underwent circumcision at our center from May 2021 to September 2022, with 228 patients in the modified disposable circumcision suture device group (mean age: 29.8 years; range: 16.8-44.9 years) and 228 patients in the disposable circumcision suture device group (mean age: 29.6 years; range: 16.4-45.1 years). Key surgical outcomes, including surgical time, intraoperative blood loss, postoperative edema duration, time for complete shedding of titanium pins, and incision healing time, were recorded and analyzed. Additionally, postoperative complications (such as injury to the penile frenulum, frenulum misalignment, glans ischemia, severe bleeding, and infection) as well as patient experiences (including intraoperative and postoperative pain scores and satisfaction with the cosmetic appearance of the penis) were evaluated.

RESULTS

All surgeries were successfully completed. The surgical duration was significantly longer in the modified disposable circumcision suture device group (5.7 ± 0.5 minutes) compared to the disposable circumcision suture device group (4.2 ± 0.6 minutes) (P < .05), indicating that the modified procedure took longer to perform. However, no significant differences were found between the 2 groups regarding intraoperative blood loss (3.2 ± 0.2 mL vs 3.2 ± 0.1 mL; P > .05), postoperative edema duration (8.2 ± 2.0 days vs 8.9 ± 1.9 days; P > .05), time for complete shedding of titanium pins (13.7 ± 1.3 days vs 13.8 ± 1.3 days; P > .05), and healing time (21.8 ± 1.7 days vs 21.9 ± 1.8 days; P > .05). The incidence of complications, including injury to the penile frenulum (0% vs 0%), glans ischemia (0% vs 0%), severe bleeding (1.3% vs 1.8%), and infection (2.6% vs 3.1%), was comparable between the 2 groups (P > .05 for all comparisons). Notably, the incidence of frenulum misalignment was significantly lower in the modified disposable circumcision suture device group (2.2% vs 16.7% in the disposable circumcision suture device group; P < .05). Moreover, patient satisfaction with the cosmetic appearance of the penis was higher in the modified disposable circumcision suture device group compared with the disposable circumcision suture device group (96.5% vs 86.8%; P < .05). The pain scores recorded during and after the procedures showed no significant intergroup differences (intraoperative: 1.7 ± 1.0 vs 1.7 ± 0.9; postoperative: 1.3 ± 1.0 vs 1.3 ± 1.0; P > .05 for all comparisons).

CONCLUSION

The modified circumcision technique using a DCSD is associated with a longer operative time; however, it effectively minimizes the risk of preputial frenulum misalignment and enhances postoperative cosmetic satisfaction.

Deficits and opportunities, pivots and shifts for scaling-up voluntary medical male circumcision in Uganda: a qualitative reflexive thematic analysis study

Despite voluntary medical male circumcision (VMMC) being a cost-effective intervention for preventing HIV transmission, its scale-up has faced challenges. Several interventions to address these challenges in priority countries, including Uganda, have not yielded the desired results. This cross-sectional qualitative study aimed to explore the factors that affect the demand for VMMC and identify possible solutions. Semi-structured phone interviews were conducted with 29 males aged at least 18 and not more than 65 drawn randomly from a database representative of the general population maintained by an independent research organisation. Reflexive thematic analysis was conducted, and data analysis was done using NVivo version 12. The results were presented in narrative format with supporting quotes. The study received ethical and regulatory clearance to be conducted in Uganda. The average age of the respondents was 28 years. Almost all respondents had some education, and most lived in rural areas. Two themes were generated, namely, 1) deficits and opportunities for VMMC, which are issues that currently hinder the uptake of VMMC but, if addressed, would lead to better demand, and 2) pivots and shifts for VMMC, which are changes that need to be made to improve the uptake of VMMC. We found that several challenges, including myths, misconceptions, health system gaps, and uncertainties about the postoperative period, hindered the uptake of VMMC. Pivots and shifts for improving the uptake of VMMC include intensifying VMMC campaigns, addressing inequities, and addressing access barriers. We concluded that several challenges, including myths and misconceptions, health system-related gaps, and uncertainties in the post-circumcision period, persist and negatively impact the scale-up of VMMC in Uganda. VMMC beneficiaries have plausible proposals for addressing challenges. The Uganda Ministry of Health should address the myths, misconceptions, health system-related gaps, and uncertainties about the postoperative period and should involve VMMC beneficiaries in reviewing interventions to address gaps.

Factors influencing neonatal male circumcision uptake among expecting couples in Zambia: formative findings

Male circumcision is a protective HIV prevention strategy. However, uncircumcised Zambian men are reluctant to undergo voluntary medical male circumcision (VMMC). Tailored interventions are necessary to stimulate the uptake of early infant male circumcision (EIMC) and VMMC in Zambia. This feasibility study presents the formative process of utilising the PRECEDE framework in the development of a family-centred EIMC/VMMC intervention, Like Father Like Son, and its application in an existing VMMC intervention, Spear & Shield. We found that fear of the pain associated with EIMC procedures, foreskin disposal, beliefs in children's autonomy and rights, and men's dominance in health decision-making were factors affecting EIMC uptake. Perceived benefits for infants included improved hygiene, protection from HIV infection, and faster recovery. Reinforcing factors included female partners and fathers' MC status. The availability and access to EIMC services and information, skill and experience of health workers, and engagement and belief in traditional circumcision practices were factors enabling EIMC uptake. These individual, interpersonal, and structural factors positively and negatively influencing EIMC uptake in the Zambian clinic context were integrated into the intervention for expecting parents. Feedback from community advisory boards suggested the process was effective in developing a culturally tailored and acceptable EIMC/VMMC promotion intervention.

Substantial but spatially heterogeneous progress in male circumcision for HIV prevention in South Africa

BACKGROUND

Voluntary medical male circumcision (VMMC) reduces the risk of male HIV acquisition by 60%. Programmes to provide VMMCs for HIV prevention have been introduced in sub-Saharan African countries with high HIV burden. Traditional circumcision is also a long-standing male coming-of-age ritual, but practices vary considerably across populations. Accurate estimates of circumcision coverage by age, type, and time at subnational levels are required for planning and delivering VMMCs to meet targets and evaluating their impacts on HIV incidence.

METHODS

We developed a Bayesian competing risks time-to-event model to produce region-age-time-type specific probabilities and coverage of male circumcision with probabilistic uncertainty. The model jointly synthesises data from household surveys and health system data on the number of VMMCs conducted. We demonstrated the model using data from five household surveys and VMMC programme data to produce estimates of circumcision coverage for 52 districts in South Africa between 2008 and 2019.

RESULTS

Nationally, in 2008, 24.1% (95% CI: 23.4-24.8%) of men aged 15-49 were traditionally circumcised and 19.4% (18.9-20.0%) were medically circumcised. Between 2010 and 2019, 4.25 million VMMCs were conducted. Circumcision coverage among men aged 15-49 increased to 64.0% (63.2-64.9%) and medical circumcision coverage to 42% (41.3-43.0%). Circumcision coverage varied widely across districts, ranging from 13.4 to 86.3%. The average age of traditional circumcision ranged between 13 and 19 years, depending on local cultural practices.

CONCLUSION

South Africa has made substantial, but heterogeneous, progress towards increasing medical circumcision coverage. Detailed subnational information on coverage and practices can guide programmes to identify unmet need to achieve national and international targets.

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

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.

Circumcision and Sexual Medicine

INTRODUCTION

Male circumcision is one of the most frequently performed and debated urological procedures due to its possible implications for sexual health.

OBJECTIVES

The objective of this article is to review the literature on male circumcision and reconcile the scientific evidence to improve the quality of care, patient education, and clinician decision-making regarding the effects on sexual function of this procedure.

METHODS

A review of the published literature regarding male circumcision was performed on PubMed. The criteria for selecting resources prioritized systematic reviews and cohort studies pertinent to sexual dysfunction, with a preference for recent publications.

RESULTS

Despite the conflicting data reported in articles, the weight of the scientific evidence suggests there is not sufficient data to establish a direct association between male circumcision and sexual dysfunction.

CONCLUSION

This review provides clinicians with an updated summary of the best available evidence on male circumcision and sexual dysfunction for evidenced-based quality of care and patient education.

HIV, syphilis, and hepatitis B virus infection and male circumcision in five Sub-Saharan African countries: Findings from the Population-based HIV Impact Assessment surveys, 2015-2019

Voluntary medical male circumcision (VMMC) has primarily been promoted for HIV prevention. Evidence also supports that male circumcision offers protection against other sexually transmitted infections. This analysis assessed the effect of circumcision on syphilis, hepatitis B virus (HBV) infection and HIV. Data from the 2015 to 2019 Population-based HIV Impact Assessments (PHIAs) surveys from Rwanda, Tanzania, Uganda, Zambia, and Zimbabwe were used for the analysis. The PHIA surveys are cross-sectional, nationally representative household surveys that include biomarking testing for HIV, syphilis and HBV infection. This is a secondary data analysis using publicly available PHIA data. Univariate and multivariable logistic regression models were created using pooled PHIA data across the five countries to assess the effect of male circumcision on HIV, active and ever syphilis, and HBV infection among sexually active males aged 15-59 years. Circumcised men had lower odds of syphilis infection, ever or active infection, and HIV, compared to uncircumcised men, after adjusting for covariates (active syphilis infection = 0.67 adjusted odds ratio (aOR), 95% confidence interval (CI), 0.52-0.87, ever having had a syphilis infection = 0.85 aOR, 95% CI, 0.73-0.98, and HIV = 0.53 aOR, 95% CI, 0.47-0.61). No difference between circumcised and uncircumcised men was identified for HBV infection (P = 0.75). Circumcised men have a reduced likelihood for syphilis and HIV compared to uncircumcised men. However, we found no statistically significant difference between circumcised and uncircumcised men for HBV infection.

HIV infection

The AIDS epidemic has been a global public health issue for more than 40 years and has resulted in ~40 million deaths. AIDS is caused by the retrovirus, HIV-1, which is transmitted via body fluids and secretions. After infection, the virus invades host cells by attaching to CD4 receptors and thereafter one of two major chemokine coreceptors, CCR5 or CXCR4, destroying the host cell, most often a T lymphocyte, as it replicates. If unchecked this can lead to an immune-deficient state and demise over a period of ~2-10 years. The discovery and global roll-out of rapid diagnostics and effective antiretroviral therapy led to a large reduction in mortality and morbidity and to an expanding group of individuals requiring lifelong viral suppressive therapy. Viral suppression eliminates sexual transmission of the virus and greatly improves health outcomes. HIV infection, although still stigmatized, is now a chronic and manageable condition. Ultimate epidemic control will require prevention and treatment to be made available, affordable and accessible for all. Furthermore, the focus should be heavily oriented towards long-term well-being, care for multimorbidity and good quality of life. Intense research efforts continue for therapeutic and/or preventive vaccines, novel immunotherapies and a cure.

Genital Herpes Infection: Progress and Problems

Genital herpes (GH) is a sexually transmitted infection causing recurrent, self-limited genital, buttock, and thigh ulcerations. Symptoms range from unrecognized or mild to severe with frequent recurrences. Herpes simplex viruses (HSV) type-1 or type-2 cause GH. HSV establishes latency in sacral ganglia and causes lifelong infection. Viral reactivation leads to genital ulceration or asymptomatic shedding which may lead to transmission. HSV infection during pregnancy can cause fulminant hepatitis and neonatal transmission. Severe and atypical manifestations are seen in immunocompromised people. Guanosine analogs treat symptoms and prevent recurrences, shedding, and transmission. Novel preventive and therapeutic strategies are in development.

Association between male circumcision and human papillomavirus infection in males and females: a systematic review, meta-analysis, and meta-regression

BACKGROUND

Previous studies have suggested a protective effect of male circumcision on human papillomavirus (HPV) infections in males, and that this protection may be conferred to their female sexual partners.

OBJECTIVES

To synthesize the available evidence on the association between male circumcision and HPV infections in males and females.

DATA SOURCES

We searched MEDLINE, Embase, Scopus, Cochrane, LILACS, and ProQuest Dissertations & Theses Global for records published up to 22 June 2022.

STUDY ELIGIBILITY

We considered observational and experimental studies that assessed male circumcision status and HPV prevalence, incidence, or clearance in males or females for inclusion.

PARTICIPANTS

Males and their female sexual partners who were tested for genital HPV infection.

INTERVENTIONS

Male circumcision compared to no circumcision.

RISK OF BIAS ASSESSMENT

The Newcastle-Ottawa scale was used for observational studies and the Cochrane risk-of-bias tool was used for randomized trials.

DATA SYNTHESIS

We estimated summary measures of effect and 95% confidence intervals (CI) for the prevalence, incidence, and clearance of HPV infections in males and females using random-effects meta-analysis. We assessed effect modification of circumcision on HPV prevalence by penile site in males using random-effects meta-regression.

RESULTS

Across 32 studies, male circumcision was associated with decreased odds of prevalent HPV infections (OR 0.45, CI 0.34-0.61), a reduced incidence rate of HPV infections (IRR 0.69, CI 0.57-0.83), and an increased risk of clearing HPV infections (RR 1.44, CI 1.28-1.61) at the glans penis among male subjects. Circumcision conferred greater protection against infection at the glans than shaft (OR 0.68, 95% CI 0.48-0.98). Females with circumcised partners were protected from all outcomes.

CONCLUSIONS

Male circumcision may protect against various HPV infection outcomes, suggesting its prophylactic potential. Understanding site-specific effects of circumcision on HPV infection prevalence has important implications for studies of HPV transmission.

Human Papillomavirus Vaccine

Cervical cancer is the fourth most common cancer in women worldwide with immense associated morbidity and mortality. Although most of the cervical cancer cases are caused by the human papillomavirus (HPV) and can effectively be prevented by HPV vaccination, vaccination unfortunately remains underused on a global scale with vast inequities in distribution. A vaccine as a tool to prevent cancer, cervical and others, is largely unprecedented. Then why do HPV vaccination rates globally remain so low? This article explores the burden of disease, development of the vaccine and its subsequent uptake, cost-effectiveness, and associated equity issues.

Voluntary Medical Male Circumcision for HIV Prevention: a Global Overview

PURPOSE OF REVIEW

With the promise of HIV prevention, there has been a scale-up of voluntary medical male circumcision (VMMC) in high HIV incidence/low circumcision prevalence nations worldwide. Nonetheless, debates over the implementation and the effectiveness and safety of the VMMC in real-world settings persist. We revisit the role of VMMC in HIV prevention to inform health professionals, policymakers, and advocates or opponents in this new era.

RECENT FINDINGS

There has been substantial progress on VMMC scale-up to date, but this has varied considerably by region. The evidence of solid and direct protection of VMMC is available for heterosexual men and older adolescent boys in sub-Saharan Africa. The protective effect in men who have sex with men is suggested by systematic reviews but is not confirmed by clinical trials. Sexual partners, including women, likely benefit indirectly from the increased VMMC coverage through a decreased risk of exposure to infected male partners. Fortunately, the preponderance of studies does not suggest higher sexual risk behaviors among circumcised men, so-called risk compensation. VMMC requires health systems strengthening and continued promulgation of other evidence-based HIV prevention strategies to be successful. Health authorities in high HIV incidence areas that have low circumcision coverage should implement VMMC within a context of complementary biomedical and behavioral prevention strategies.

The Effects of Medical Male Circumcision on Female Partners' Sexual and Reproductive Health

PURPOSE OF REVIEW

Voluntary medical male circumcision (VMMC) reduces the risk of HIV acquisition by 60% among heterosexual men, provides protection against certain sexually transmitted infections (STI), and leads to penile microbiome composition changes associated with reduced risk of HIV infection. Intuitively, the benefits of VMMC for female sex partners in relation to STI are likely and have been evaluated. The purpose of this review is to examine emerging findings of broader sexual and reproductive health (SRH) benefits of VMMC for female sex partners.

RECENT FINDINGS

Systematic reviews find strong evidence for beneficial effects of VMMC on female sex partners risk of HPV, cervical dysplasia, cervical cancer, and with likely protection against trichomoniasis and certain genital ulcerative infections. Few studies assess the direct impact of VMMC on the vaginal microbiome (VMB), though several studies demonstrate reductions in BV, which is mediated by the VMB. Studies are lacking regarding male circumcision status and outcomes associated with non-optimal VMB, such as female infertility and adverse pregnancy outcomes. VMMC has positive effects on women's perceptions of sexual function and satisfaction, and perceptions of disease risk and hygiene, without evidence of risk compensation. VMMC has consistent association with a broad range of women's SRH outcomes, highlighting the biological and non-biological interdependencies within sexual relationships, and need for couples-level approaches to optimize SRH for men and women. The paucity of information on VMMC and influence on VMB is a barrier to optimizing VMB-associated SRH outcomes in female partners.

Estimating the effect of HIV on cervical cancer elimination in South Africa: Comparative modelling of the impact of vaccination and screening

Background

In 2020, the World Health Organization (WHO) launched its initiative to eliminate cervical cancer as a public health problem. To inform global efforts for countries with high HIV and cervical cancer burden, we assessed the impact of human papillomavirus (HPV) vaccination and cervical cancer screening and treatment in South Africa, on cervical cancer and the potential for achieving elimination before 2120, considering faster HPV disease progression and higher cervical cancer risk among women living with HIV(WLHIV) and HIV interventions.

Methods

Three independent transmission-dynamic models simulating HIV and HPV infections and disease progression were used to predict the impact on cervical cancer incidence of three scenarios for all women: 1) girls' vaccination (9-14 years old), 2) girls' vaccination plus 1 lifetime cervical screen (at 35 years), and 3) girls' vaccination plus 2 lifetime cervical screens (at 35 and 45 years) and three enhanced scenarios for WLHIV: 4) vaccination of young WLHIV aged 15-24 years, 5) three-yearly cervical screening of WLHIV aged 15-49 years, or 6) both. Vaccination assumed 90% coverage and 100% lifetime protection with the nonavalent vaccine (against HPV-16/18/31/33/45/52/58). Cervical cancer screening assumed HPV testing with uptake increasing from 45% (2023), 70% (2030) to 90% (2045+). We also assumed that UNAIDS 90-90-90 HIV treatment and 70% male circumcision targets are reached by 2030. We examined three elimination thresholds: age-standardised cervical cancer incidence rates below 4 or 10 per 100,000 women-years, and >85% reduction in cervical cancer incidence rate. We conducted sensitivity analyses and presented the median age-standardised predictions of outcomes of the three models (minimum-maximum across models).

Findings

Girls' vaccination could reduce age-standardised cervical cancer incidence from a median of 47.6 (40.9-79.2) in 2020 to 4.5 (3.2-6.3) per 100,000 women-years by 2120, averting on average ∼4% and ∼46% of age-standardised cumulative cervical cancer cases over 25 and 100 years, respectively, compared to the basecase. Adding 2 lifetime screens helped achieve elimination over the century among all women (2120 cervical cancer incidence: 3.6 (1.9-3.6) per 100,000 women-years), but not among WLHIV (10.8 (5.3-11.6)), and averted more cumulative cancer cases overall (∼45% over 25 years and ∼61% over 100 years compared to basecase) than girls' vaccination alone. Adding three-yearly cervical screening among WLHIV (to girls' vaccination and 2 lifetime cervical screens) further reduced age-standardised cervical cancer incidence to 3.3 (1.8-3.6) per 100,000 women-years overall and to 5.2 (3.9-8.5) among WLHIV by 2120 and averted on average 12-13% additional cumulative cancer cases among all women and 21-24% among WLHIV than girls' vaccination and 2 lifetime cervical screens over 25 years or longer. Long-term vaccine protection and using the nonavalent vaccine was required for elimination.

Interpretation

High HPV vaccination coverage of girls and 2 lifetime cervical screens could eliminate cervical cancer among women overall in South Africa by the end of the century and substantially decrease cases among all women and WLHIV over the short and medium term. Cervical cancer elimination in WLHIV would likely require enhanced prevention strategies for WLHIV. Screening of WLHIV remains an important strategy to reduce incidence and alleviate disparities in cervical cancer burden between women with and without HIV, despite HIV interventions scale-up.

Infant Circumcision for Sexually Transmitted Infection Risk Reduction Globally

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.

Genital Herpes Simplex Virus-An Updated Review

The herpes virus was named by the Greek physician Hippocrates who called it herpes because the lesions appeared near each other and were vesicular. Alphaherpesvirinae, Betaherpesvirinae, and Gammaherpesvirinae are subfamilies of the human herpes virus family. The Alphaherpesvirinae subfamily includes the simplex viruses-HSV-1 and HSV-2-and varicellovirus-varicella zoster virus. There are more than 200 members of the Herpesviridae family capable of infecting different species, 8 of which are known to cause disease in humans. The simplex viruses can cause lifelong genital infections, and despite the prevalence of HSV-1 and HSV-2 infections in the United States decreasing in the past 20 years, infections with these viruses continue to contribute to significant clinical and psychological morbidities.

Evidence-based circumcision policy for Australia

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.

Diagnosis and Management of Genital Herpes: Key Questions and Review of the Evidence for the 2021 Centers for Disease Control and Prevention Sexually Transmitted Infections Treatment Guidelines

Genital herpes, caused by herpes simplex virus (HSV) type 1 or type 2, is a prevalent sexually transmitted infection (STI). Given that HSV is an incurable infection, there are important concerns about appropriate use of diagnostic tools, management of infection, prevention of transmission to sexual partners, and appropriate counseling. In preparation for updating the Centers for Disease Control and Prevention (CDC) STI treatment guidelines, key questions for management of genital herpes infection were developed with a panel of experts. To answer these questions, a systematic literature review was performed, with tables of evidence including articles that would change guidance assembled. These data were used to inform recommendations in the 2021 CDC STI treatment guidelines.

What is the medical evidence on non-therapeutic child circumcision?

Non-therapeutic circumcision refers to the surgical removal of part or all of the foreskin, in healthy males, where there is no medical condition requiring surgery. The arguments for and against this practice in children have been debated for many years, with conflicting and conflicted evidence presented on both sides. Here, we explore the evidence behind the claimed benefits and risks from a medical and health-related perspective. We examine the number of circumcisions which would be required to achieve each purported benefit, and set that against the reported rates of short- and long-term complications. We conclude that non-therapeutic circumcision performed on otherwise healthy infants or children has little or no high-quality medical evidence to support its overall benefit. Moreover, it is associated with rare but avoidable harm and even occasional deaths. From the perspective of the individual boy, there is no medical justification for performing a circumcision prior to an age that he can assess the known risks and potential benefits, and choose to give or withhold informed consent himself. We feel that the evidence presented in this review is essential information for all parents and practitioners considering non-therapeutic circumcisions on otherwise healthy infants and children.

Semen: A modulator of female genital tract inflammation and a vector for HIV-1 transmission

In order to establish productive infection in women, HIV must transverse the vaginal epithelium and gain access to local target cells. Genital inflammation contributes to the availability of HIV susceptible cells at the female genital mucosa and is associated with higher HIV transmission rates in women. Factors that contribute to genital inflammation may subsequently increase the risk of HIV infection in women. Semen is a highly immunomodulatory fluid containing several bioactive molecules with the potential to influence inflammation and immune activation at the female genital tract. In addition to its role as a vector for HIV transmission, semen induces profound mucosal changes to prime the female reproductive tract for conception. Still, most studies of mucosal immunity are conducted in the absence of semen or without considering its immune impact on the female genital tract. This review discusses the various mechanisms by which semen exposure may influence female genital inflammation and highlights the importance of routine screening for semen biomarkers in vaginal specimens to account for its impact on genital inflammation.

Sexually Transmitted Infections Treatment Guidelines, 2021

These guidelines for the treatment of persons who have or are at risk for sexually transmitted infections (STIs) were updated by CDC after consultation with professionals knowledgeable in the field of STIs who met in Atlanta, Georgia, June 11-14, 2019. The information in this report updates the 2015 guidelines. These guidelines discuss 1) updated recommendations for treatment of Neisseria gonorrhoeae, Chlamydia trachomatis, and Trichomonas vaginalis; 2) addition of metronidazole to the recommended treatment regimen for pelvic inflammatory disease; 3) alternative treatment options for bacterial vaginosis; 4) management of Mycoplasma genitalium; 5) human papillomavirus vaccine recommendations and counseling messages; 6) expanded risk factors for syphilis testing among pregnant women; 7) one-time testing for hepatitis C infection; 8) evaluation of men who have sex with men after sexual assault; and 9) two-step testing for serologic diagnosis of genital herpes simplex virus. Physicians and other health care providers can use these guidelines to assist in prevention and treatment of STIs.

Understanding ethnic variations in HIV prevalence in Kenya: the role of cultural practices

Patterns of HIV prevalence in Kenya suggest that areas where various cultural practices are prevalent bear a disproportionate burden of HIV. This paper examines (i) the contextual effects of cultural practices (polygyny, male circumcision) and related sexual behaviour factors on HIV prevalence and (ii) the extent to which specific cultural practices in a community/county might explain existing ethnic variations in HIV prevalence in Kenya. The analysis applies multilevel logistic regression to data from the 2012/13 Kenya AIDS Indicator Survey. The results reveal striking ethnic variations in HIV prevalence in Kenya. The prevalence of polygyny in a community is positively associated with HIV prevalence, while a higher level of male circumcision in a county is protective for both men and women. The effects of these factors are stronger for men than women at both individual and contextual (community/county) levels. These cultural practices and associated risk factors partly explain existing ethnic differences in HIV prevalence in Kenya, but there remain significant ethnic variations that are not explained by these cultural practices or related sexual behaviour factors. These call for stronger empirical evidence to offer stronger theoretical explanations and inform effective policy and practice to address HIV epidemic in adversely affected communities in Kenya and similar settings in sub-Saharan Africa.

Genitourinary Infections Related to Circumcision and the Potential Impact on Male Infertility

Male circumcision (MC) is one of the oldest surgical procedures still completed today. Medical indications for MC include phimosis, recurrent balanitis, cosmesis, and infection prevention. In this review, we mainly focus on the role of MC in the prevention of human immunodeficiency virus, human papillomavirus, herpes simplex virus, gonorrhea, chlamydia, chancroid, and syphilis, and the subsequent impact of these genitourinary infections on male fertility. Overall, many compelling data support that MC may play an essential role in both genitourinary infection prevention and male fertility.

A comparison of the prevalence of sexually transmitted infections among circumcised and uncircumcised adult males in Rustenburg, South Africa: a cross-sectional study

BACKGROUND

South Africa has a persistent burden of sexually transmitted infections (STIs). Male circumcision has been shown to be effective in preventing HIV and STIs, but data are scarce on the protective effect of circumcision in high-risk populations such as migrant miners. The objective of this study was to assess the effect of medical and traditional circumcision on the prevalence of STIs after adjusting for other risk factors in Rustenburg, a mining town in North West Province, South Africa.

METHODS

This cross-sectional study used baseline data collected from a cohort study. Adult males in a mining town were assessed for STIs (gonorrhea, chlamydia, and trichomoniasis) using syndromic assessment. Data on circumcision status and other risk factors for STI syndromes were collected using an interviewer-administered questionnaire. The following symptoms were assessed; penile discharge, painful urination, dyspareunia or penile sores. These symptoms indicate sexually transmitted infection in general since laboratory tests were not performed. Multivariable log binomial regression was used to assess the independent effect of circumcision on STI presence after adjusting for confounders.

RESULTS

A total of 339 participants with a median age of 25 years (IQR 22-29) were included in the study, of whom 116 (34.2%) were circumcised. The overall STIs prevalence was 27.4% (95% CI 22.8 to 32.6%) and was lower in the circumcised participants compared with those who were uncircumcised (15.5% vs 33.6%, respectively, p < 0.001). Both medical (OR 0.57, 95% CI 0.34-0.95, p = 0.030) and traditional circumcision (OR 0.34, 95% CI 0.13-0.86, p = 0.022) were strongly associated with a lower risk of STIs after adjustment for employment and condom use.

CONCLUSION

In this high-risk population in a mining town in South Africa, with a relatively high prevalence of STIs, and where one third of males are circumcised, both medical and traditional circumcision appear to be protective against STIs.

A Modified Pressure Dressing to Avoid Severe Bleeding After Circumcision With a Disposable Circumcision Suture Device and a Discussion on the Mechanism of Bleeding With the Disposable Circumcision Suture Device

INTRODUCTION

A novel type of a disposable circumcision suture device (DCSD) has been proved to be effective and safe; however, a few cases of severe bleeding took place after circumcisions.

AIM

To evaluate the effectiveness of a modified double-layer pressure dressing to avoid severe bleeding after circumcision with the DCSD, in our department in a prospective randomized controlled study, and discuss the mechanism of bleeding with DCSD.

METHODS

Patients with redundant foreskin or phimosis were included between September 2018 and November 2019 and divided into 2 groups: In group A, the conventional pressure dressing was performed; in group B, an modified double-layer pressure dressing was performed.

MAIN OUTCOME MEASURE

The main outcomes and complications (surgical time, incidence of glans ischemia, severe bleeding rate, infection rate, pain level, total cost, and overall satisfaction) were collected and analyzed.

RESULTS

A total of 624 patients were recruited for this study. There was no difference in the average age and body mass index between 2 groups. No patient suffered obvious glans ischemia. In group B, lower pain level, lower incidences of severe bleeding, and better satisfaction were recorded.

CONCLUSION

The mechanism of bleeding with the DCSD was discussed in this study, and the modified pressure dressing was proved effective, safe, and easy to perform. W Jiang, J-li Fu, W-l Guo, et al.

Sexually transmitted infections (STI) and antenatal care (ANC) clinics in Malawi: effective platforms for improving engagement of men at high HIV risk with voluntary medical male circumcision services

Introduction

Voluntary medical male circumcision (VMMC), an effective HIV prevention programme for men, is implemented in East and Southern Africa. Approximately 50% of VMMC clients are aged below 15 years. More targeted interventions to reach older men and others at higher short-term HIV risk are needed.

Methods

We implemented a quality improvement project testing the effectiveness of an active referral-based VMMC recruitment approach, targeting men attending STI clinics and those escorting partners to antenatal care (ANC) clinics, at Bwaila Hospital in Lilongwe, Malawi. We compared the proportions aged older than 15 years among men who received VMMC following referral from STI and ANC clinics with those among men referred from standard community mobilisation. We also analysed referral cascades to VMMC.

Results

In total, 330 clients were circumcised after referral from STI (242) and ANC (88) clinics, as compared with 3839 other clients attributed to standard community mobilisation. All clients from ANC and STI clinics were aged over 15 years, as compared with 69% from standard community mobilisation. STI clinics had a higher conversion rate from counselling to VMMC than ANC (12% vs 9%) and a higher contribution to total circumcisions performed at the VMMC clinic (6% vs 2%).

Conclusions

Integrating VMMC recruitment and follow-up in STI and ANC clinics co-located with VMMC services can augment demand creation and targeting of men at risk of HIV, based on age and STI history. This approach can be replicated at least in similar health facilities with ANC and STI services in close proximity to VMMC service delivery.

Male circumcision uptake and its predictors among sexually active men aged 15-59 years living in the highest HIV prevalence region of Ethiopia: evidence from 2016 Ethiopia demographic and health survey

Background

Pieces of evidence showed that the Gambella region of Ethiopia has remained HIV hotspot area for successive years. However, the magnitude of male circumcision uptake and its associated factors are not well studied in this region. Hence, the aim of the current study is to assess the magnitude of male circumcision uptake and its predictors among sexually active men in the region using the 2016 Ethiopian Demographic and Health Survey Data.

Method

Data on 868 sexually active men residing in the Gambella region were extracted from the 2016 Ethiopian Demographic and health Survey. Descriptive statistics and logistic regression were respectively used to summarize descriptive data and measure the statistical associations. Adjusted odds ratio and confidence intervals were respectively used to measure statistical associations between variables and their statistical significances.

Results

The current study revealed that the overall prevalence of male circumcision uptake in the Gambella region was 61.2% (95% CI: 57.96,64.44). The results of multivariable logistic regression revealed that being Muslim (AOR = 9.54, 95% CI: 6.765.13.88), being Orthodox Christian (AOR = 8.5, 95%CI: 5.00–14.45), being from Poor household (AOR = 0.11, 95%CI: 0.06, 0.22), being from medium-income household (AOR = .33, 95%CI: 0.15, 0.73), listening to radio (AOR = .29, 95%CI: .16, .54), having comprehensive HIV knowledge (AOR = .44, 95%CI: .27, .71) and ever been tested for HIV (AOR = .27, 95%CI: .16,.46) were independently associated with male circumcision uptake.

Conclusion

Despite all efforts made by different stakeholders to promote the provision of male circumcision in the Gambella region, its magnitude of uptake is still unacceptably low. The federal HIV prevention and Control Office and other stakeholders working on HIV prevention and control should give due emphasis to promoting HIV-related knowledge through community-based education and through religious leaders. Integrating and streamlining HIV-related education in the academic curricula, and expanding mass media coverage should also be given due consideration by the federal government and other stakeholders. The stakeholders should also give emphasis to strengthening and empowering poor sexually active men residing in the Gambella region.

Lay knowledge of cervical cancer in Manhiça district, Mozambique: a qualitative study

Background

Mozambique has one of the highest cervical cancer incidence rates in the world. Health interventions are still being conceived solely from a non-communicable disease standpoint despite that it is also a sexual and reproductive health problem. The objective of this study was to assess the extent to which lay perceptions of cervical cancer align with biomedical knowledge from the standpoint of sexual and reproductive health.

Methods

10 focus group discussions were carried out with 10 target groups in Manhiça. The target groups were diverse in terms of age, sex, educational level and occupation. There were a total of 116 participants. The focus groups discussions were applied to obtain verbal information and trigger debates around beliefs and attitudes about cervical cancer as well as to explore notions of transmission and aetiology of the disease. The discussions were recorded for later transcription and analysis, following a combination of content and thematic analysis.

Results

Participants were familiar with the biomedical term ‘cervical cancer’ but knowledge of its aetiology and transmission was limited. Cervical cancer was readily associated to sexual transmission and sexually transmitted infections, and conceived as a ‘wound that does not heal’. The term ‘cancer’ caused confusion, as it was perceived to happen only in limbs, understood as hereditary, not transmissible and as an illness of the West.

Conclusions

Lay perceptions of cervical cancer do, to a large extent, align with biomedical ones, thus, there is common ground to frame future health interventions from a sexual and reproductive health standpoint. Some misperceptions were identified which could be reduced through social behaviour change communication initiatives.

The Impact of Male Partner Circumcision on Women's Health Outcomes

Medical male circumcision is a proven method of HIV risk reduction in men with no known direct benefit to women. We investigated the benefit of partner circumcision on women's health. We conducted a secondary analysis of 5,029 women enrolled in the Vaginal and Oral Interventions to Control the Epidemic trial across 15 African sites, to look at the impact of partner circumcision status on sexually transmitted infections, pregnancy, frequency of sex, and condom use in women. Of 4,982 participants with a baseline response, 31% had circumcised partners. Women with circumcised partners had a significantly reduced risk of syphilis acquisition, hazard ratio 0.51 (0.26, 1.00), p value = .05. Participants with uncircumcised partners were significantly less likely to have used a condom at the last sex act than the other two groups, adj. relative risk 0.86 (0.80, 0.92), adj. p value < .0001. We found no evidence of sexual risk compensation in women with circumcised partners.

The Penile Microbiota in Uncircumcised and Circumcised Men: Relationships With HIV and Human Papillomavirus Infections and Cervicovaginal Microbiota

While the human microbiota especially that of the gut, cervix, and vagina continue to receive great attention, very little is currently known about the penile (glans, coronal sulcus, foreskin, and shaft) microbiota. The best evidences to date for the potential role of the penile microbiota in human immunodeficiency virus (HIV) and other sexually transmitted infections (STIs) acquisition have come from studies examining medical male circumcision. We are still at the foothills of identifying specific penile bacteria that could be associated with increased risk of STI/HIV acquisition. In this review, we summarize the available literature on the human penile microbiota and how it is impacted by circumcision. We also discuss the potential role of penile microbiota in STIs and its impact on cervicovaginal microbiota. Taken together, the findings from the penile microbiota studies coupled with observational studies on the effect of male circumcision for reduction of STI/HIV infection risk suggest that specific penile anaerobic bacteria such as Prevotella spp. potentially have a mechanistic role that increases the risk of genital infections and syndromes, including bacterial vaginosis in sexual partners. Although penile Corynebacterium and Staphylococcus have been associated with healthy cervicovaginal microbiota and have been found to increase following male circumcision, further investigations are warranted to ascertain the exact roles of these bacteria in the reproductive health of men and women. This review aims to address existing gaps and challenges and future prospects in the penile microbiota research. The information described here may have translational significance, thereby improving reproductive health and management of STI/HIV.

Mapping male circumcision for HIV prevention efforts in sub-Saharan Africa

BACKGROUND

HIV remains the largest cause of disease burden among men and women of reproductive age in sub-Saharan Africa. Voluntary medical male circumcision (VMMC) reduces the risk of female-to-male transmission of HIV by 50-60%. The World Health Organization (WHO) and Joint United Nations Programme on HIV/AIDS (UNAIDS) identified 14 priority countries for VMMC campaigns and set a coverage goal of 80% for men ages 15-49. From 2008 to 2017, over 18 million VMMCs were reported in priority countries. Nonetheless, relatively little is known about local variation in male circumcision (MC) prevalence.

METHODS

We analyzed geo-located MC prevalence data from 109 household surveys using a Bayesian geostatistical modeling framework to estimate adult MC prevalence and the number of circumcised and uncircumcised men aged 15-49 in 38 countries in sub-Saharan Africa at a 5 × 5-km resolution and among first administrative level (typically provinces or states) and second administrative level (typically districts or counties) units.

RESULTS

We found striking within-country and between-country variation in MC prevalence; most (12 of 14) priority countries had more than a twofold difference between their first administrative level units with the highest and lowest estimated prevalence in 2017. Although estimated national MC prevalence increased in all priority countries with the onset of VMMC campaigns, seven priority countries contained both subnational areas where estimated MC prevalence increased and areas where estimated MC prevalence decreased after the initiation of VMMC campaigns. In 2017, only three priority countries (Ethiopia, Kenya, and Tanzania) were likely to have reached the MC coverage target of 80% at the national level, and no priority country was likely to have reached this goal in all subnational areas.

CONCLUSIONS

Despite MC prevalence increases in all priority countries since the onset of VMMC campaigns in 2008, MC prevalence remains below the 80% coverage target in most subnational areas and is highly variable. These mapped results provide an actionable tool for understanding local needs and informing VMMC interventions for maximum impact in the continued effort towards ending the HIV epidemic in sub-Saharan Africa.

The past, present and future impact of HIV prevention and control on HPV and cervical disease in Tanzania: A modelling study

Background

Women with HIV have an elevated risk of HPV infection, and eventually, cervical cancer. Tanzania has a high burden of both HIV and cervical cancer, with an HIV prevalence of 5.5% in women in 2018, and a cervical cancer incidence rate among the highest globally, at 59.1 per 100,000 per year, and an estimated 9,772 cervical cancers diagnosed in 2018. We aimed to quantify the impact that interventions intended to control HIV have had and will have on cervical cancer in Tanzania over a period from 1995 to 2070.

Methods

A deterministic transmission-dynamic compartment model of HIV and HPV infection and natural history was used to simulate the impact of voluntary medical male circumcision (VMMC), anti-retroviral therapy (ART), and targeted pre-exposure prophylaxis (PrEP) on cervical cancer incidence and mortality from 1995–2070.

Findings

We estimate that VMMC has prevented 2,843 cervical cancer cases and 1,039 cervical cancer deaths from 1995–2020; by 2070 we predict that VMMC will have lowered cervical cancer incidence and mortality rates by 28% (55.11 cases per 100,000 women in 2070 without VMMC, compared to 39.93 with VMMC only) and 26% (37.31 deaths per 100,000 women in 2070 without VMMC compared to 27.72 with VMMC), respectively. We predict that ART will temporarily increase cervical cancer diagnoses and deaths, due to the removal of HIV death as a competing risk, but will ultimately further lower cervical cancer incidence and mortality rates by 7% (to 37.31 cases per 100,000 women in 2070) and 5% (to 26.44 deaths per 100,000 women in 2070), respectively, relative to a scenario with VMMC but no ART. A combination of ART and targeted PrEP use is anticipated to lower cervical cancer incidence and mortality rates to 35.82 and 25.35 cases and deaths, respectively, per 100,000 women in 2070.

Conclusions

HIV treatment and control measures in Tanzania will result in long-term reductions in cervical cancer incidence and mortality. Although, in the near term, the life-extending capability of ART will result in a temporary increase in cervical cancer rates, continued efforts towards HIV prevention will reduce cervical cancer incidence and mortality over the longer term. These findings are critical background to understanding the longer-term impact of achieving cervical cancer elimination targets in Tanzania.

Medical Male Circumcision and Associations Among Sexually Transmitted Infections Service Attendees

Medical male circumcision (MMC) is a proven intervention for preventing HIV acquisition among males. We describe the circumcision status, eligibility for MMC referral and associations with HIV positivity among symptomatic males attending sexually transmitted infections (STI) services. This study was a secondary analysis of cross-sectional data collected during sentinel surveillance for STI aetiologies. In the sentinel surveillance conducted at primary care facilities located in six South African provinces, an anonymous questionnaire was administered followed by collection of appropriate genital and blood specimens for laboratory testing including HIV, rapid plasma reagin (RPR) and HSV-2 serological testing. During analysis, multivariable logistic regression was used to determine association between prevalent HIV infection and male circumcision among males who were HSV-2 AND/OR RPR serology positive and among those who were negative. A total of 847 males were included the analysis, among whom the median age was 28 years (IQR 24-32 years) with 26.3% aged < 25 years. Of these, 166 (19.6%) were medically circumcised, 350 (41.4%) traditionally circumcised while 324 (39%) were not circumcised. The yield of assessment for MMC referral was 27.7%. Overall HIV positivity was 23.1%. Compared to no circumcision, MMC had a statistically insignificant 62% lower odds of being HIV positive -among males who were HSV-2 and RPR negative- adjusted odds ratio [aOR] 0.38 [95% confidence interval (CI) 0.12-1.18], p = 0.094. Among those HSV-2 AND/OR RPR positive, MMC had a statistically insignificant 26% lower odds of being HIV positive- aOR 0.74 (95% CI 0.41-1.36), p = 0.334. In both groups HIV positivity increased with age but was positively associated with condom use at last sexual encounter [aOR 3.41 (95% CI 1.43-8.15)] and previous treatment for an STI syndrome [aOR 3.81 (95% CI 1.60-9.05)] among those HSV-2 and RPR negative. High HIV positivity and high yield of eligibility for VMMC referral among males attending STI services points to the need for better integration of HIV prevention and treatment with STI care.

Noncandidal vaginitis: a comprehensive approach to diagnosis and management

Vaginitis is one of the most common causes of patient visits to gynecologists, primary care providers, and urgent care centers. However, many women leave without a clear diagnosis or experience recurrent symptoms despite treatment. The 3 most common etiologies of vaginitis are trichomonas, bacterial vaginosis, and vulvovaginal candidiasis, which account for an estimated 70% of cases. The remaining 30% may be related to other causes of vaginitis, including atrophic vaginitis, desquamative inflammatory vaginitis, and vaginal erosive disease. The purpose of this review is to describe the noncandidal causes of acute and recurrent vaginitis, with the goal of improving the likelihood of accurate diagnosis as well as efficient and effective therapy. We excluded candidal vaginitis from our review because there was a recently published review on this topic in the Journal. The clinical presentation and evaluation of patients with symptoms of vaginitis can be triaged into 1 of 2 diagnostic pathways: noninflammatory and inflammatory vaginitis. The most common noninflammatory cause is bacterial vaginosis. Features such as irritation, purulent discharge, and the presence of polymorphonuclear neutrophils are more suggestive of an inflammatory process. Trichomoniasis is the most common cause of inflammatory vaginitis. Other well-described forms of inflammatory vaginitis include atrophic vaginitis, desquamative inflammatory vaginitis, and erosive disease. We present a review of the pathogenesis, symptoms, examination findings, diagnostic testing, and treatment for each of these causes of noncandidal vaginitis.

Epidemiology of Treponema pallidum, Chlamydia trachomatis, Neisseria gonorrhoeae, Trichomonas vaginalis, and herpes simplex virus type 2 among female sex workers in the Middle East and North Africa: systematic review and meta-analytics

BACKGROUND

The epidemiology of sexually transmitted infections (STIs) and the role of commercial heterosexual sex networks in driving STI transmission in the Middle East and North Africa (MENA) region remain largely unknown.

OBJECTIVE

To characterize the epidemiology of Treponema pallidum (syphilis), Chlamydia trachomatis, Neisseria gonorrhoeae, Trichomonas vaginalis, and herpes simplex virus type 2 (HSV-2) among female sex workers (FSWs) in MENA using an in-depth quantitative assessment.

METHODS

A systematic review on ten international, regional, and country-level databases was conducted, and reported following PRISMA guidelines. Pooled prevalences of current and/or ever infection for each STI were estimated using random-effects meta-analyses. Sources of between-study heterogeneity were investigated through random-effects meta-regressions.

RESULTS

One T. pallidum incidence study and 144 STI prevalence studies were identified for 45 812 FSWs in 13 MENA countries. The pooled prevalence of current infection was 12.7% (95% confidence interval (CI) = 8.5%-17.7%) for T. pallidum, 14.4% (95% CI = 8.2%-22.0%) for C. trachomatis, 5.7% (95% CI = 3.5%-8.4%) for N. gonorrhoeae, and 7.1% (95% CI = 4.3%-10.5%) for T. vaginalis. The pooled prevalence of ever infection (seropositivity using antibody testing) was 12.8% (95% CI = 9.4%-16.6%) for T. pallidum, 80.3% (95% CI = 53.2%-97.6%) for C. trachomatis, and 23.7% (95% CI = 10.2%-40.4%) for HSV-2. The multivariable meta-regression for T. pallidum infection demonstrated strong subregional differences, with the Horn of Africa and North Africa showing, respectively 6-fold (adjusted odds ratio (AOR): 6.4; 95% CI = 2.5-16.7) and 5-fold (AOR = 5.0; 95% CI = 2.5-10.6) higher odds of infection than Eastern MENA. There was also strong evidence for declining T. pallidum odds of infection at 7% per year (AOR = 0.93; 95% CI = 0.88-0.98). Study-specific factors including diagnostic method, sample size, sampling methodology, and response rate, were not associated with syphilis infection. The multivariable model explained 48.5% of the variation in T. pallidum prevalence.

CONCLUSIONS

STI infection levels among FSWs in MENA are considerable, supporting a key role for commercial heterosexual sex networks in transmission dynamics, and highlighting the health needs of this neglected and vulnerable population. Syphilis prevalence in FSWs appears to have been declining for at least three decades. Gaps in evidence persist for multiple countries.

Critical evaluation of arguments opposing male circumcision: A systematic review

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.

Use of Lotteries for the Promotion of Voluntary Medical Male Circumcision Service: A Discrete-Choice Experiment among Adult Men in Tanzania

Voluntary medical male circumcision (VMMC) is effective in reducing the risk of human immunodeficiency virus (HIV). However, countries like Tanzania have high HIV prevalence but low uptake of VMMC. We conducted a discrete-choice experiment to evaluate the preferences for VMMC service attributes in a random sample of 325 men aged 18 years or older from the general population in 2 Tanzanian districts, Njombe and Tabora. We examined the preference for financial incentives in the form of a lottery ticket or receiving a guaranteed transport voucher for attendance at a VMMC service. We created a random-parameters logit model to account for individual preference heterogeneity and a latent class analysis model for identifying groups of men with similar preferences to test the hypothesis that men who reported sexually risky behaviors (i.e., multiple partners and any condomless sex in the past 12 months) may have a preference for participation in a lottery-based incentive. Most men preferred a transport voucher (84%) over a lottery ticket. We also found that offering a lottery-based financial incentive may not differentially attract those with greater sexual risk. Our study highlights the importance of gathering local data to understand preference heterogeneity, particularly regarding assumptions around risk behaviors.

Does voluntary medical male circumcision protect against sexually transmitted infections among men and women in real-world scale-up settings? Findings of a household survey in KwaZulu-Natal, South Africa

INTRODUCTION

Male circumcision (MC) confers partial protection to men against HIV and, in research settings, some sexually transmitted infections (STIs). It is also associated with protection from some STIs among female partners. However, real-world data on changes in STI transmission associated with large-scale public African medical male circumcision (MMC) conducted for HIV prevention are lacking and would improve estimates of the health impact of MMC.

METHODS

The HIV Incidence Provincial Surveillance System is a community-based surveillance platform for HIV prevalence, incidence and intervention coverage trends in KwaZulu-Natal province, South Africa. HIPPS collected cross-sectional self-reported data on circumcision status (from men), partner circumcision status for past three partners (from women) and demographic characteristics and behavioural risk factors; and tested participants for HIV, herpes simplex virus type 2 (HSV-2), syphilis, hepatitis B, N eisseria gonorrhoeae, C hlamydia trachomatis, Trichomonas vaginalis and Mycoplasma genitalium. Bivariable and multivariable analyses were performed on associations between own (men) or partner's (women) circumcision status and each STI. Multivariable analyses adjusted for age, demographic characteristics and behavioural risk factors, and incorporated false discovery rate (FDR) correction.

RESULTS

Among men, MMC had a protective association with HSV-2 (OR 0.66, 95% CI 0.50 to 0.86), hepatitis B (OR 0.53, 95% CI 0.30 to 0.95), HIV (OR 0.50, 95% CI 0.38 to 0.65) and M. genitalium (OR 0.53, 95% CI 0.32 to 0.88). Among women, partner circumcision had a protective association with HSV-2 (OR 0.71, 95% CI 0.53 to 0.95) and HIV (OR 0.66, 95% CI 0.49 to 0.90). Associations with HIV and HSV-2 remained significant for men and all women after FDR correction.

CONCLUSION

These real-world data, supporting protective associations between MMC conducted for HIV prevention and STIs in men and women, can help clarify the full impact of MMC and support a role in broader sexual health programming.

Application of an HIV Prevention Cascade to Identify Gaps in Increasing Coverage of Voluntary Medical Male Circumcision Services in 42 Rural Zambian Communities

Increased coverage of voluntary medical male circumcision (VMMC) is needed in countries with high HIV prevalence. We applied an HIV-prevention cascade to identify gaps in male circumcision coverage in Zambia. We used survey data collected in 2013 and 2014/15 to describe circumcision coverage at each time-point, and prevalence of variables related to demand for and supply of VMMC. We explored whether circumcision coverage in 2014/15 was associated with demand and supply among uncircumcised men in 2013. Results show that circumcision coverage was 11.5% in 2013 and 18.0% in 2014/15. Levels of having heard of circumcision and agreeing with prevention benefits was similar at both time-points (79.8% vs 83.2%, and 49.7% vs 50.7%, respectively). In 2013, 39.3% of men perceived services to be available compared to 54.7% in 2014/15. Levels of having heard of circumcision in 2013 was correlated with and higher perceived service availability associated with coverage in 2014/15. VMMC coverage was low in these study sites. Knowledge of prevention tools and of service availability are necessary to increase coverage but alone are insufficient.

Association of Male Circumcision with Women's Knowledge of its Biomedical Effects and With Their Sexual Satisfaction and Function: A Systematic Review

Male circumcision (MC) is a key HIV prevention intervention for men in countries with high HIV prevalence. Women's understanding of MC is important but poorly understood. We conducted a systematic review including women's knowledge of MC's biomedical impacts and its association with female sexual satisfaction and function through October 2017. Thirty-eight articles were identified: thirty-two with knowledge outcomes, seven with sexual satisfaction, and four with sexual function (N = 38). Respondent proportions aware MC protects men from HIV were 9.84-91.8% (median 60.0%). Proportions aware MC protects men from STIs were 14.3-100% (72.6%). Proportions aware MC partially protects men from HIV were 37.5-82% (50.7%). Proportions aware MC is not proven to protect women from infection by an HIV-positive partner were 90.0-96.8% (93.0%). No increases over time were noted. Women's MC knowledge is variable. Education could help women support MC and make better-informed sexual decisions.

Does Male Circumcision Reduce Women's Risk of Sexually Transmitted Infections, Cervical Cancer, and Associated Conditions?

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.

Adult gonorrhea, chlamydia and syphilis prevalence, incidence, treatment and syndromic case reporting in South Africa: Estimates using the Spectrum-STI model, 1990-2017

OBJECTIVES

To estimate trends in prevalence and incidence of syphilis, gonorrhea and chlamydia in adult men and women in South Africa.

METHODS

The Spectrum-STI tool estimated trends in prevalence and incidence of active syphilis, gonorrhea and chlamydia, fitting South African prevalence data. Results were used, alongside programmatic surveillance data, to estimate trends in incident gonorrhea cases resistant to first-line treatment, and the reporting gap of symptomatic male gonorrhea and chlamydia cases treated but not reported as cases of urethritis syndrome.

RESULTS

In 2017 adult (15-49 years) the estimated female and male prevalences for syphilis were 0.50% (95% CI: 0.32-0.80%) and 0.97% (0.19-2.28%), for gonorrhea 6.6% (3.8-10.8%) and 3.5% (1.7-6.1%), and for chlamydia 14.7% (9.9-21%) and 6.0% (3.8-10.4%), respectively. Between 1990 and 2017 the estimated prevalence of syphilis declined steadily in women and men, probably in part reflecting improved treatment coverage. For gonorrhea and chlamydia, estimated prevalence and incidence showed no consistent time trend in either women or men. Despite growing annual numbers of gonorrhea cases - reflecting population growth - the estimated number of first line treatment-resistant gonorrhea cases did not increase between 2008 and 2017, owing to changes in first-line antimicrobial treatment regimens for gonorrhea in 2008 and 2014/5. Case reporting completeness among treated male urethritis syndrome episodes was estimated at 10-28% in 2017.

CONCLUSION

South Africa continues to suffer a high STI burden. Improvements in access and quality of maternal, STI and HIV health care services likely contributed to the decline in syphilis prevalence. The lack of any decline in gonorrhea and chlamydia prevalence highlights the need to enhance STI services beyond clinic-based syndromic case management, to reinvigorate primary STI and HIV prevention and, especially for women, to screen for asymptomatic infections.

Progress in voluntary medical male circumcision for HIV prevention supported by the US President's Emergency Plan for AIDS Relief through 2017: longitudinal and recent cross-sectional programme data

OBJECTIVE

This article provides an overview and interpretation of the performance of the US President's Emergency Plan for AIDS Relief's (PEPFAR's) male circumcision programme which has supported the majority of voluntary medical male circumcisions (VMMCs) performed for HIV prevention, from its 2007 inception to 2017, and client characteristics in 2017.

DESIGN

Longitudinal collection of routine programme data and disaggregations.

SETTING

14 countries in sub-Saharan Africa with low baseline male circumcision coverage, high HIV prevalence and PEPFAR-supported VMMC programmes.

PARTICIPANTS

Clients of PEPFAR-supported VMMC programmes directed at males aged 10 years and above.

MAIN OUTCOME MEASURES

Numbers of circumcisions performed and disaggregations by age band, result of HIV test offer, procedure technique and follow-up visit attendance.

RESULTS

PEPFAR supported a total of 15 269 720 circumcisions in 14 countries in Southern and Eastern Africa. In 2017, 45% of clients were under 15 years of age, 8% had unknown HIV status, 1% of those tested were HIV+ and 84% returned for a follow-up visit within 14 days of circumcision.

CONCLUSIONS

Over 15 million VMMCs have been supported by PEPFAR since 2007. VMMC continues to attract primarily young clients. The non-trivial proportion of clients not testing for HIV is expected, and may be reassuring that testing is not being presented as mandatory for access to circumcision, or in some cases reflect test kit stockouts or recent testing elsewhere. While VMMC is extremely safe, achieving the highest possible follow-up rates for early diagnosis and intervention on complications is crucial, and programmes continue to work to raise follow-up rates. The VMMC programme has achieved rapid scale-up but continues to face challenges, and new approaches may be needed to achieve the new Joint United Nations Programme on HIV/AIDS goal of 27 million additional circumcisions through 2020.
