Pros and cons of circumcision: an evidence-based overview

Prevalence and economic burden of male anogenital wart in Korea: A population-based big data analysis from 2007 to 2018

PURPOSE

To investigate the prevalence of anogenital warts (AGW) caused by human papillomavirus in men and the characteristics and changes of the disease in Korea.

MATERIALS AND METHODS

From 2007 to 2018, male AGW corresponding to the International Classification of Disease-10 A63.0 were targeted. Through a big data analysis of the Health Insurance Review & Assessment Service, data of patients diagnosed with AGW as either the main or secondary diagnosis were extracted. The overall prevalence and prevalence by age were calculated through the population by year and the population by 5-year-old unit of the National Statistical Office. Additionally, the amount accrued through the disease code was confirmed and compared as AGW-related medical expenses.

RESULTS

The annual number of patients increased by 3.5 times from 32,709 in 2007 to 114,734 in 2018. Additionally, the annual prevalence increased by 3.34 times from 132.83 per 100,000 to 443.57. The age-specific prevalence was the highest among the 25- to 29-year age group. The highest prevalence was observed in the 25- to 29-year age group in 2018 (1,492.15 per 100,000), and the lowest was noted in the 10- to 14-year age group in 2014 (7.28 per 100,000). AGW-related medical expenses increased by approximately 9.76 times from US$ 2,789,215.1 in 2007 to US$ 27,227,254.9 in 2018.

CONCLUSIONS

In Korea, cases of male AGW are increasing yearly, with the 25- to 29-year age group having the highest prevalence. Medical costs related to AGW are also increasing tenfold. For male AGW, further studies and national interventions are needed.

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.

Circumferential full-thickness skin grafting: An excellent method for the treatment of short penile skin in adult men

Objective

Short penile skin due to excessive circumcision is a complex condition requiring surgical care. The study aims to investigate the effect of full-thickness skin grafting (FTSG) in treating short penile skin.

Methods

A retrospective analysis was performed on 24 patients with insufficient penile skin. The included patients underwent full-thickness skin grafting from the scrotum and the groin region in the Genital Plastic Surgery Center between February 2014 and September 2021. Morphology of the penis, length of the penis, complication, and donor area healing status was observed by the authors. Additionally, the International Index of Erectile Function Questionnaire (IIEF-5) and the patient's evaluation of penile appearance were investigated.

Results

An aesthetically pleasing appearance of the penis was obtained by FTSG in 24 patients. The length of penis was improved after surgery (5.70 cm ± 1.24 cm vs. 6.05 cm ± 1.33 cm, P value < 0.05). All patients had good healing of the penile area without serious complications. Only 2 cases showed minor partial necrosis and recovered soon after proper treatment. A high patient's evaluation of penile appearance was received (4.08 ± 0.71, mean ± SD) and the scores of IIEF-5 increased significantly after surgery (18.38 ± 2.24 vs. 21.08 ± 1.79, P-value < 0.05).

Conclusions

FTSG from the scrotum and inguinal skin provides good aesthetic and functional results for treating short penile skin. FTSG, particularly the scrotum-derived skin graft, offers a great supplement to penile skin. It could be suggested as a promising method of treating insufficient penile skin, which meets both functional and aesthetic needs.

Incidence of circumcision among insured adults in the United States

Purpose

Although circumcision is the most commonly performed surgery in males, less is known about the incidence and indications of adult circumcision. In this study, we aim to present the incidence of adult circumcision across the United States.

Methods

Using IBM MarketScan^® Commercial Database from 2015 to 2018, we obtained claims for circumcision in men between 18 and 64 years of age. We calculated the incidence of adult circumcision over the study period and across the United States. We also collected data on indications for surgery using International Classification of Diseases codes.

Results

We identified a total of 12,298 claims for adult circumcisions. The mean age was 39 (±12.9) years. The average incidence rates remained relatively constant from 98.1 per 100,000 person-years in 2015 to 98.2 per 100,000 person-years in 2018 (Δ+0.1%). The age-standardized incidence rates varied significantly across the United States (from 0 to 194.8 per 100,000 person-years) with South Dakota having the highest rate. The most common indications for adult circumcision were phimosis (52.5%), routine/ritual circumcision (28.7%), phimosis + balanitis/balanoposthitis (6.8%), balanitis (3.8%) and balanoposthitis (2.6%), and significantly varied by age groups.

Conclusion

This study suggested a wide geographic variation in rates of adult circumcision between states with highest incidences in the Northeast United States. Future studies can identify the underlying causes for the observed variations.

Heineke-Mikulicz Preputioplasty: Surgical Technique and Outcomes

OBJECTIVE

To provide a summary of surgical technique and outcomes for Heineke-Mikulicz preputioplasty (HMP), a foreskin-preserving surgical treatment for phimosis in the adult population.

METHODS

We retrospectively reviewed 7 patients who underwent HMP by a single surgeon from May 2017 to May 2021. Variables included patient demographics, intraoperative considerations, and post-operative course. HMP is performed using a 2-3 cm vertical incision over the phimotic band on the dorsal surface to just above Buck's fascia. Additional incisions are made on the ventral surface if phimosis remains persistent after dorsal release. The incision is closed horizontally in 2 layers.

RESULTS

Seven patients underwent HMP. Median age was 47.3 and median BMI was 24.3. Five patients reported bothersome phimosis and 1 each reported paraphimosis and frenular tethering. Six patients requested foreskin sparing surgery as a personal preference and 1 patient was an intraoperative consult. Topical betamethasone was attempted in 3 of 7 patients. The median time from diagnosis to surgery was 2 months. Median operative time was 45.5 minutes and median estimated blood loss was 5 mL. Two patients required both dorsal and ventral incisions. No intraoperative complications were reported and all patients were discharged the same day. At median follow-up of 1.8 months, 1 patient reported bothersome phimosis secondary to scar formation treated successfully with triamcinolone.

CONCLUSION

HMP is a safe and effective method of treating even very significant phimosis in patients trying to avoid circumcision or intraoperative consults where preferences may be unclear. Our method takes less time than traditional circumcision with a comparable recovery and complication profile.

Impact of Sexual Activity on the Risk of Male Genital Tumors: A Systematic Review of the Literature

Most cancers are related to lifestyle and environmental risk factors, including smoking, alcohol consumption, dietary habits, and environment (occupational exposures). A growing interest in the association between sexual activity (SA) and the development of different types of tumors in both men and women has been recorded in recent years. The aim of the present systematic review is to describe and critically discuss the current evidence regarding the association between SA and male genital cancers (prostatic, penile, and testicular), and to analyze the different theories and biological mechanisms reported in the literature. A comprehensive bibliographic search in the MEDLINE, Scopus, and Web of Science databases was performed in July 2021. Papers in the English language without chronological restrictions were selected. Retrospective and prospective primary clinical studies, in addition to previous systematic reviews and meta-analyses, were included. A total of 19 studies, including 953,704 patients were selected. Case reports, conference abstracts, and editorial comments were excluded. Men with more than 20 sexual partners in their lifetime, and those reporting more than 21 ejaculations per month, reported a decreased risk of overall and less aggressive prostate cancer (PCa). About 40% of penile cancers (PCs) were HPV-associated, with HPV 16 being the dominant genotype. Data regarding the risk of HPV in circumcised patients are conflicting, although circumcision appears to have a protective role against PC. Viral infections and epididymo-orchitis are among the main sex-related risk factors studied for testicular cancer (TC); however, data in the literature are limited. Testicular trauma can allow the identification of pre-existing TC. SA is closely associated with the development of PC through high-risk HPV transmission; in this context, phimosis appears to be a favoring factor. Sexual behaviors appear to play a significant role in PCa pathogenesis, probably through inflammatory mechanisms; however, protective sexual habits have also been described. A direct correlation between SA and TC has not yet been proven, although infections remain the most studied sex-related factor.

Circumcision as an Intervening Strategy against HIV Acquisition in the Male Genital Tract

Unsafe sex with HIV-infected individuals remains a major route for HIV transmission, and protective strategies, such as the distribution of free condoms and pre-or post-prophylaxis medication, have failed to control the spread of HIV, particularly in resource-limited settings and high HIV prevalence areas. An additional key strategy for HIV prevention is voluntary male circumcision (MC). International health organizations (e.g., the World Health Organization, UNAIDS) have recommended this strategy on a larger scale, however, there is a general lack of public understanding about how MC effectively protects against HIV infection. This review aims to discuss the acquisition of HIV through the male genital tract and explain how and why circumcised men are more protected from HIV infection during sexual activity than uncircumcised men who are at higher risk of HIV acquisition.

The impact of the program for medical male circumcision on HIV in South Africa: analysis using three epidemiological models

Background: South Africa began offering medical male circumcision (MMC) in 2010. We evaluated the current and future impact of this program to see if it is effective in preventing new HIV infections. Methods: The Thembisa, Goals and Epidemiological Modeling Software (EMOD) HIV transmission models were calibrated to South Africa's HIV epidemic, fitting to household survey data on HIV prevalence, risk behaviors, and proportions of men circumcised, and to programmatic data on intervention roll-out including program-reported MMCs over 2009-2017. We compared the actual program accomplishments through 2017 and program targets through 2021 with a counterfactual scenario of no MMC program. Results: The MMC program averted 71,000-83,000 new HIV infections from 2010 to 2017. The future benefit of the circumcision already conducted will grow to 496,000-518,000 infections (6-7% of all new infections) by 2030. If program targets are met by 2021 the benefits will increase to 723,000-760,000 infections averted by 2030. The cost would be $1,070-1,220 per infection averted relative to no MMC. The savings from averted treatment needs would become larger than the costs of the MMC program around 2034-2039. In the Thembisa model, when modelling South Africa's 9 provinces individually, the 9-provinces-aggregate results were similar to those of the single national model. Across provinces, projected long-term impacts were largest in Free State, KwaZulu-Natal and Mpumalanga (23-27% reduction over 2017-2030), reflecting these provinces' greater MMC scale-up. Conclusions: MMC has already had a modest impact on HIV incidence in South Africa and can substantially impact South Africa's HIV epidemic in the coming years.

Using data from 'visible' populations to estimate the size and importance of 'hidden' populations in an epidemic: A modelling technique

We used reported behavioural data from cisgender men who have sex with men and transgender women (MSM/TGW) in Bangalore, mainly collected from 'hot-spot' locations that attract MSM/TGW, to illustrate a technique to deal with potential issues with the representativeness of this sample. A deterministic dynamic model of HIV transmission was developed, incorporating three subgroups of MSM/TGW, grouped according to their reported predominant sexual role (insertive, receptive or versatile). Using mathematical modelling and data triangulation for 'balancing' numbers of partners and role preferences, we compared three different approaches to determine if our technique could be useful for inferring characteristics of a more 'hidden' insertive MSM subpopulation, and explored their potential importance for the HIV epidemic. Projections for 2009 across all three approaches suggest that HIV prevalence among insertive MSM was likely to be less than half that recorded in the surveys (4.5-6.5% versus 13.1%), but that the relative size of this subgroup was over four times larger (61-69% of all MSM/TGW versus 15%). We infer that the insertive MSM accounted for 10-20% of all prevalent HIV infections among urban males aged 15-49. Mathematical modelling can be used with data on 'visible' MSM/TGW to provide insights into the characteristics of 'hidden' MSM. A greater understanding of the sexual behaviour of all MSM/TGW is important for effective HIV programming. More broadly, a hidden subgroup with a lower infectious disease prevalence than more visible subgroups, has the potential to contain more infections, if the hidden subgroup is considerably larger in size.

Acceptability and Barriers to HIV Pre-Exposure Prophylaxis in Atlanta's Adolescents and Their Parents

Adolescents aged 13-24 years account for 23% of new HIV infections in Atlanta, indicating need for better HIV prevention strategies in this population. Pre-exposure prophylaxis (PrEP) is now approved for adolescent use. This study aims to understand the acceptability of and barriers to PrEP in adolescents and parents. We administered PrEP acceptability and barrier measures to HIV(-) 13-17 year olds and their parents from January to April 2016 in an adolescent clinic and emergency department in Atlanta, GA, stratifying by adolescent sexual activity. Acceptability scores (AS) and barrier scores (BS) were calculated by averaging survey answers 1-3. For AS, 1 was very unlikely to accept PrEP; concomitantly, BS near 3 indicated fewer barriers. Two-sample hypothesis testing, Pearson correlations, and linear regression were used. Of the 102 adolescent/parent dyads, 67% of adolescents were female, 94% black, with a mean age of 15.7 ± 1.5 years, and 31% were sexually active. Parents were 94% female, 96% black, with a mean age of 42.4 ± 8.9 years. AS averaged between somewhat to very likely to accept PrEP (2.4 ± 0.5 and 2.2 ± 0.6) in adolescents and parents, respectively. BS averaged between unlikely and somewhat likely to perceive barriers to PrEP (2.0 ± 0.4 and 1.9 ± 0.5) in adolescents and parents, respectively. The adolescent/parent dyad is likely to accept PrEP, regardless of sexual activity. Limitations include that nearly 70% of adolescents were not sexually active, and the study was conducted before PrEP approval by the Food and Drug Administration for those who are younger than 18 years. These results support future parent and adolescent education on PrEP.

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.

High subsequent and recurrent sexually transmitted infection prevalence among newly diagnosed HIV-positive Thai men who have sex with men and transgender women in the Test and Treat cohort

We determined subsequent and recurrent sexually transmitted infections (STIs) among men who have sex with men (MSM) and transgender women (TGW) in the Test and Treat cohort. Thai MSM and TGW adults with previously unknown HIV status were enrolled and tested for HIV. Chlamydia trachomatis (CT), Neisseria gonorrhoeae (NG), and syphilis were tested at baseline, month 12, and month 24 to identify subsequent STIs (any STIs diagnosed after baseline) and recurrent STIs (any subsequent STIs diagnosed among those with positive baseline STIs). Among 448 participants, 17.8% were HIV-positive, the prevalence of subsequent STIs and recurrent STIs was 42% (HIV-positive versus HIV-negative: 66.3% versus 36.7%, p < 0.001) and 62.3% (81% versus 52.5%, p < 0.001), respectively. Common subsequent STIs by anatomical site were rectal CT infection (21.7%), rectal NG infection (13.8%), pharyngeal NG infection (13.1%), and syphilis (11.9%). HIV-positive status was associated with both subsequent STIs (adjusted hazard ratio [aHR] 2.38; 95%CI 1.64-3.45, p < 0.001) and recurrent STIs (aHR 1.83; 95%CI 1.16-2.87, p = 0.01). The results show that newly diagnosed HIV-positive MSM and TGW were at increased risk of STIs despite being in the healthcare system. STI educational counseling is necessary to improve STI outcomes among MSM and TGW in both HIV prevention and treatment programs.

Proven prevention tools for addressing STI epidemics

The ongoing rise of sexually transmitted infections (STIs) poses a global public health challenge and the risk of acquiring one of these infections depends upon sexual practices, the number of sexual encounters and the location of that individual within the sexual network. Commercial sex workers (CSWs) have potentially a pivotal role in the transmission of STIs; however, a new study presented in this journal describes markers of risk but no increase in infections amongst men who pay for sex (MPS). This commentary highlights some of the growing evidence regarding STI prevention and the value of using these tools to protect CSWs, their clients and by extension the sexual partners of MPS.

Attitudes, Beliefs and Predictors of Male Circumcision Promotion among Medical University Students in a Traditionally Non-Circumcising Region

Objective: To evaluate the beliefs of medical university students regarding male circumcision (MC), as well as attitudes and the predictors of its promotion in the case of adults at risk of HIV. Methods: A cross-sectional survey was conducted between 2013-2016 at the Medical University in Szczecin, Poland, among final year Polish/foreign students from Northern Europe, using a standardized questionnaire. Results: There were 539 participants, median age 25 years, 40.8% males, and 66.8% were Polish nationals. The MC rate was 16.7%. Regarding HIV/AIDS knowledge, 66.6% of the students scored more than 75%; and, 34.2% knew that MC reduces the risk of HIV infection. One in eleven respondents (9.1%) believed that circumcised men felt more intense sexual pleasure. More than half of the respondents (54.8%) declared that they would recommend MC to adult patients at risk for HIV. The belief that circumcised men felt more intense sexual pleasure, and knowledge on MC regarding HIV risk reduction was associated with greater odds of recommending adult MC (OR = 3.35 and OR = 2.13, respectively). Conclusions: Poor knowledge of its benefits and a low willingness to promote the procedure-strongly dependent on personal beliefs-suggest that medical students may need additional training to help them to discuss MC more openly with adult men at risk for HIV infection. Knowledge may be an effective tool when making decisions regarding MC promotion.

Low HIV incidence in pregnant and postpartum women receiving a community-based combination HIV prevention intervention in a high HIV incidence setting in South Africa

Background

Young Southern African women have the highest HIV incidence globally. Pregnancy doubles the risk of HIV acquisition further, and maternal HIV acquisition contributes significantly to the paediatric HIV burden. Little data on combination HIV prevention interventions during pregnancy and lactation are available. We measured HIV incidence amongst pregnant and postpartum women receiving a community-based combination HIV prevention intervention in a high HIV incidence setting in South Africa.

Methods

A cohort study that included HIV-uninfected pregnant women was performed. Lay community-based workers provided individualized HIV prevention counselling and performed three-monthly home and clinic-based individual and couples HIV testing. Male partners were referred for circumcision, sexually transmitted infections or HIV treatment as appropriate. Kaplan-Meier analyses and Cox’s regression were used to estimate HIV incidence and factors associated with HIV acquisition.

Results

The 1356 women included (median age 22.5 years) received 5289 HIV tests. Eleven new HIV infections were detected over 828.3 person-years (PY) of follow-up, with an HIV incidence rate of 1.33 infections/100 PY (95% CI: 0.74–2.40). Antenatally, the HIV incidence rate was 1.49 infections/100 PY (95% CI: 0.64–2.93) and postnatally the HIV incidence rate was 1.03 infections/100 PY (95% CI: 0.33–3.19). 53% of male partners received HIV testing and 66% of eligible partners received referral for circumcision. Women within known serodiscordant couples, and women with newly diagnosed HIV-infected partners, adjusted hazard ratio (aHR) = 32.7 (95% CI: 3.8–282.2) and aHR = 126.4 (95% CI: 33.8–472.2) had substantially increased HIV acquisition, respectively. Women with circumcised partners had a reduced risk of incident HIV infection, aHR = 0.22 (95% CI: 0.03–1.86).

Conclusions

Maternal HIV incidence was substantially lower than previous regional studies. Community-based combination HIV prevention interventions may reduce high maternal HIV incidence in resource-poor settings. Expanded roll-out of home-based couples HIV testing and initiating pre-exposure prophylaxis for pregnant women within serodiscordant couples is needed in Southern Africa.
