Prevalence of HPV genital infection in patients with moderate-to-severe psoriasis undergoing systemic treatment with immunosuppressive agents or biologics.

Psoriasis is an immune-mediated inflammatory disease and its relationship with infection has been extensively investigated. Concern for the increased prevalence of human papilloma virus (HPV) infection in patients undergoing systemic immunomodulatory or immunosuppressive therapies for psoriasis has been gradually growing among clinicians. To evaluate the prevalence of HPV in a cohort of patients with psoriasis treated with currently available systemic, conventional and biotechnological drugs. A multi-centric prospective study was conducted in the main dermatological clinical centres of central and southern Italy. Data from 588 patients (366 males and 222 females) with moderate-to-severe psoriasis, aged ≥18 years and treated with conventional and biological drugs, were collected based on a documented history of HPV infection, a positive Papanicolaou test (Pap-test) when available, and clinical evidence of genital warts reported during consultation. Overall, 18 of 588 patients (3.6% [95% CI: 1.8-4.5]) were positive for HPV or had a history of cervical cancer. Considering anamnestic and demographic data, such as gender, age, smoking, weight and body mass index, no statistically significant differences between HPV+ and HPV- patients were found. Moreover, the eradication of HPV infection was successfully achieved using conventional treatments. The prevalence of HPV infection in patients with moderate-to-severe psoriasis, undergoing systemic treatment with immunosuppressive agents or biologics, appears to be the same as that in the general Italian population, indicating that the level of infection among such patients is acceptable.

Genital Human Papillomavirus Prevalence and Genotyping Among Males in Putuo District of Shanghai, China 2015-2019.

BACKGROUND Reports of human papillomavirus (HPV) infection and genotype distribution in Chinese men are limited, and HPV vaccination has not yet been recommended for men in China. MATERIAL AND METHODS We retrospectively reviewed the prevalence and genotyping of male genital HPV. A total of 1227 male patients (aged 17 to 81 years) attending the dermatology and sexually transmitted disease clinics at Putuo District Center Hospital in Shanghai from 2015 to 2019 were included. Genital exfoliated specimens were obtained for detection and genotyping of 27 HPV types by Luminex-based multiplex assay. RESULTS The prevalence of any HPV was 65.5% (804/1227). The rate of multiple infection was 25.8% (317/1227). The 5 main HPV types were 6 (32.0%), 11 (23.2%), 16 (5.6%), 43 (4.3%), and 59 (4.0%). Among all detected HPV genotypes, 65.5% (875/1336) were 9-valent HPV genotypes. No significant differences were observed in the detection rate of HPV infection over 5 years (P>0.05). Age groups ≤24 years (70.7%) and ≥55 years (72.9%) showed higher infection rates, and significant differences were detected in rates of low-risk HPV infection in different age-stratified groups (P<0.05). Prevalence of HPV infection among patients with warts (74.4%) was significantly higher than that of patients with other clinical characteristics (40.4%) and physical examination (63.6%). CONCLUSIONS Our study suggested that more than half of Chinese male patients have detectable HPV infections, and penis-genital and anogenital warts were the most common clinical manifestations. Moreover, the available 9-valent HPV vaccine covers the most frequently observed HPV types among men.

Sequential acquisition of human papillomavirus infection between genital and oral anatomic sites in males.

Oral human papillomavirus (HPV) is associated with increasing rates of HPV-associated oropharyngeal cancer (OPC) in men. Sequential infection from one site to another has been demonstrated at the cervix and anus. Thus, risk of an oral HPV infection after a genital infection of the same type in the HPV infection in men study was investigated. Samples from 3140 men enrolled in a longitudinal cohort were assessed for sequential genital to oral infection with one of nine HPV types (HPV 6, 11, 16, 18, 31, 33, 45, 52 and 58); and then also sequential, same-type oral to genital infection. Incidence rate ratios (IRRs) compared rates of oral HPV among men with and without prior genital infection of the same type. Risk of sequential HPV infections were assessed using Cox proportional hazards model. Incidence of an oral HPV infection was significantly higher among men with a prior genital infection of the same type for any of the 9 HPV types (IRR: 2.3; 95% CI: 1.7-3.0). Hazard ratio of a sequential genital to oral HPV infection was 2.3 (95% CI: 1.7-3.1) and 3.5 (95% CI: 1.9-6.4) for oral to genital infection. Both changed minimally after adjustment for age, country, circumcision, alcohol use, lifetime sexual partners and recent oral sex partners. HPV infections at one site could elevate risk of a subsequent genital or oral HPV infection of the same type in men, emphasizing the importance of vaccination to prevent all HPV infections.

Changing Demography of Genital Chlamydia, Gonorrhea, Genital Herpes, Condyloma, and Syphilis Infections in Japan.

There was an epidemiological correlation in time and space between gonorrhea and genital chlamydia as well as between condyloma and genital herpes. There was, however, no correlation in other combinations, such as, gonorrhea and condyloma, genital herpes and chlamydia, etc. The annual incidence of gonorrhea and that of genital chlamydia were mono-phasic with a peak in 2005-2006. The annual incidence of condyloma and that of genital herpes were biphasic with the first distinct peak in 2004-2006 borne by the younger generation and the second broad peak by the older generation that experienced the first wave. The epidemiology of syphilis was entirely different from the above infections: the incidences of early, late, and asymptomatic syphilis started increasing around 2010, which was associated with a shift of patients' peak age towards the younger generation.

The changing epidemiology of genital ulcer disease in South Africa: has donovanosis been eliminated?

OBJECTIVES: We used an in-house molecular assay for the detection of Klebsiella granulomatis in ulcer specimens collected over a 12-year surveillance period in order to determine whether a diagnosis of donovanosis could be ascribed to genital ulcer disease (GUD) of unknown aetiology in our setting. METHODS: Between 2007 and 2018, a total of 974 genital ulcer specimens with no previously identified sexually transmitted (STI) pathogens were selected from STI aetiological surveys conducted in all nine provinces of South Africa. Giemsa-stained ulcer smears from the same participants had previously been routinely analysed for the presence of typical Donovan bodies within large mononuclear cells. A Klebsiella screening assay targeting the phoE (phosphate porin) gene was used in combination with restriction digest analysis and sequencing to confirm the presence of K. granulomatis. RESULTS: The Klebsiella screening assay tested positive in 19/974 (2.0%) genital ulcer specimens. Restriction digest analysis and nucleotide sequencing of the phoE gene confirmed that none of these specimens was positive for K. granulomatis DNA. Similarly, Donovan bodies were not identified in the Giemsa stained ulcer smears of these specimens. CONCLUSIONS: This is the first study to assess K. granulomatis as a cause of genital ulceration in South Africa over a 12-year surveillance period using molecular methods. The results demonstrate that K. granulomatis is no longer a prevalent cause of GUD in our population.

Burden of genital warts in Colombia: an observational study / Carga das verrugas genitais na Colômbia: um estudo observacional

Introduction: Genital warts are benign lesions caused by sexual transmission of human papillomavirus types 6 and 11, with significant impact on healthcare resource use and patients' quality of life. Objective: To describe the epidemiology of genital warts in adults visiting a physician office for any reason, physician practice patterns, and healthcare resource use and costs in Colombia. Methods: Participants were a convenience sample of 53 physicians in 5 specialties: primary care (15), gynecology (24), urology (12), proctology (1), and dermatology (1). Physicians completed a survey and daily log of all patients 18-60 years old seen over 10 days in their practices in 2016-2017. The physician survey recorded genital warts consultation and management patterns. The daily log recorded patient demographic information and genital warts diagnosis. Results: Among 6,393 patients logged by physicians, the genital warts prevalence was 2.03% (95%CI 1.69­2.38) and incidence 1.30% (95%CI 1.02­1.58). Primary care physicians referred most of their genital warts cases for treatment (female: mean 63.3%, SD=44.8; male: mean 58.3%, SD=43.8). Treatment of non-resistant episodes (<6-month duration) lasted an average of 37.4 days (SD=29.4) and required an average of 4.0 (SD=1.9) office visits for females and 3.0 (SD=1.7) for males. The overall mean cost of an episode of care was USD558.13 (SD=507.30). Conclusion: Genital warts cases reported by most participant physicians were mainly direct-consult, but patients were typically treated by specialists. Much of the genital warts health care utilization and costs reported could be prevented by immunization with the quadrivalent or nonavalent HPV vaccine.

Introdução: As verrugas genitais são lesões benignas, de transmissão sexual, causadas pelo papilomavírus humano tipos 6 e 11 e que causam impacto significativo no uso de recursos de saúde e na qualidade de vida dos pacientes. Objetivo: Descrever a epidemiologia das verrugas genitais em adultos que buscaram atendimento médico ambulatorial por qualquer motivo, incluindo padrões de prática médica, uso de recursos de saúde e custos na Colômbia. Métodos: foi utilizada uma amostra de conveniência composta por 53 médicos em 5 especialidades: clínico geral (15), ginecologia (24), urologia (12), proctologia (1) e dermatologia (1). Os médicos completaram um questionário e registros diários de todos os pacientes com idade entre 18 e 60 anos atendidos durante 10 dias em seus consultórios em 2016-2017. O questionário registrou os padrões de prática médica e de tratamento de verrugas genitais. Os registros diários continham informações demográficas do paciente e o diagnóstico de verrugas genitais. Resultados: Entre 6.393 atendimentos médicos, a prevalência das verrugas genitais foi de 2,03% (IC95% 1,69­2,38) e a incidência de 1,30% (IC95% 1,02­1,58). Os clínicos gerais encaminharam a maioria dos pacientes com verrugas genitais para tratamento (mulheres: média de 63,3%, DP=44,8; homens: média de 58,3%, DP=43,8). O tratamento dos casos não-persistentes (<6 meses de duração) durou em média 37,4 dias (DP=29,4) e requereu uma média de 4,0 (DP=1,9) consultas para mulheres e 3,0 (DP=1,7) para homens. O custo médio geral do tratamento foi de US$ 558,13 (SD=507,30). Conclusão: Os casos de verrugas genitais relatados pela maioria dos médicos participantes derivaram-se principalmente de atendimentos primários e os pacientes foram tratados geralmente por especialistas. Grande parte da utilização de recursos e custos relacionados a verrugas genitais poderia ser evitada pela imunização com a vacina papilomavírus humano 4-valente ou 9-valente.

Gender differences in genital lichen sclerosus: data from a multicenter Italian study on 729 consecutive cases.

BACKGROUND: Studies specifically conducted to assess gender differences in genital lichen sclerosus (GLS) are not available. This multicenter study aimed to identify possible gender-related differences on GLS clinical features, history and course, through collecting data from a large mixed-sex sample of patients. METHODS: This was a cross-sectional study on 729 subjects (53.8% females, 46.2% males) affected with GLS, consecutively observed within a network of 15 Italian dermatology units. The following information was specifically collected: clinical features and severity of symptoms related to GLS, extragenital involvement, previous therapies, diagnostic suspicion at referral, type of referring physicians, development of genital squamous-cell carcinoma (SCC). RESULTS: Females complained of symptoms more frequent and severe than men; pallor and scarring-sclerosis-atrophy were the most frequent features without gender differences; itching-related signs were more frequent in females than in males as well as extragenital involvement; prior to receiving a definitive diagnosis, females received treatment more frequently than males; 40% of patients were referred with a misdiagnosis; the highest rate of correct suspected diagnosis at referral came from dermatologists than from other physicians; duration of the disease was found to predispose to SCC development. CONCLUSIONS: Our findings highlighted several gender differences on clinical presentation and symptom profile of GLS. In spite of some characteristic features, misdiagnosis at referrals was frequent.

Risk behaviours and alcohol in adolescence are negatively associated with testicular volume: results from the Amico-Andrologo survey.

BACKGROUND: Risk factors established during adolescence affect health outcomes in adulthood, although little is known about how adolescent health risk behaviours (HRBs) affect testicular development and reproductive health. OBJECTIVES: To assess prevalence of HRBs among last year high school students; to describe the most prevalent andrological disorders in this cohort; to explore HRBs associated with andrological disorders and investigate factors possibly associated with impaired testicular development in puberty. MATERIALS AND METHODS: The Amico-Andrologo Survey is a permanent nationwide surveillance programme conducted by the Italian Society of Andrology and Sexual Medicine and supported by the Ministry of Health. A nationally representative survey of final-year male high school students was conducted using a validated structured interview (n = 10124) and medical examination (n = 3816). RESULTS: Smoking (32.6%), drinking (80.6%) and use of illegal drugs (46.5%) are common in adolescence. 16.6% of subjects were overweight, 3.1% were underweight and 2.3% were obese. Among sexually active students (60.3%), unprotected sex was very common (48.3%). Only 11.6% had been treated for andrological disorders, despite an abnormal clinical examination in 34.6%. Bilateral testicular hypotrophy (14.0%), varicocoele (27.1%) and phimosis (7.1%) were the most prevalent disorders; 5.1% complained of premature ejaculation and 4.7% had an STI. Underweight and heavy alcohol or drug use were associated with testicular hypotrophy. HRBs emerged as significant predictors of testicular hypotrophy, explaining up to 9.6% of its variance. Limitations include risk of selection bias for voluntary physical examination and recall bias for the self-compiled questionnaire. DISCUSSION: There is an emerging global adverse trend of HRBs in male high school students. A significant proportion of adolescent males with unsuspected andrological disorders engage in behaviours that could impair testicular development. CONCLUSION: Greater attention to the prevention of andrological health in adolescence is needed.

Genital infections due to the human papillomavirus. / Infecciones genitales por el virus del papiloma humano.

The Human Papillomavirus (HPV) is a double-stranded DNA virus, with more than 200 different genotypes having been identified. This infection is considered the most common sexually transmitted infection (STI), and it is the cause of a significant number of diseases, both benign lesions (anogenital condylomas) and pre-malignant lesions and different cancers. The diagnosis of the infection is performed by molecular techniques based on the detection of viral DNA, the mRNA of oncogenic proteins and cellular alteration caused by the infection. Although there is no consensus regarding the best treatment, this should be individualised, and there are different options with ablative treatments being more effective but with greater recurrences, and immunomodulatory treatments being less effective in the short term but with fewer recurrences. Among the preventive strategies, vaccination against HPV is the best strategy against anogenital neoplasms and warts, its maximum effectiveness being when it is administered prior to exposure to HPV.

Human Papillomavirus and Genital Disease in Men: What We Have Learned from the HIM Study.

It is currently recognized that in addition to the major impact of human papillomavirus (HPV) infection in females, HPV causes considerable disease in men at the genitals, anal canal, and oropharynx. Specifically, genital HPV infections may progress to genital warts and penile carcinoma. Although studies concerning the natural history of HPV infections and associated neoplasias have mainly focused on women, during the last 2 decades considerable attention has been given in further understanding these infections in men. The HIM (HPV infection in men) Study, the only prospective multicenter study of male HPV natural history, consisted of a large prospective international cohort study in which men from Brazil, the United States, and Mexico were enrolled. The design and protocols of this study allowed unraveling crucial information regarding the relationship between HPV infection and clinical consequences in men, and associated risk factors at each of the anatomic sites where HPV is known to cause cancer in men.

Retrospective characterization of reproductive tract lesions in relation to age, parity, and contraception in captive suidae and tayassuidae.

Reproductive management in zoos requires contraception or physical separation of sexes to ensure captive population viability, but information is sparse on the effects of parity, age, and contraceptive use on lifetime reproductive health in captive Suidae and Tayassuidae species. This retrospective study evaluated reproductive tissues and histories from babirusa (Babyrousa babyrussa), red river hog (Potamochoerus porcus), Visayan warty pig (Sus cebifrons), common warthog (Phacochoerus africanus), Vietnamese pot-bellied pig (Sus scrofa domesticus), domestic cross pig (Sus scrofa), Sunda island pig (Sus celebensis timoriensis), Eurasian boar (Sus scrofa), Bornean bearded pig (Sus barbatus), Ossabaw island hog (Sus scrofa domesticus), Guinea hog (Sus scrofa domesticus), Chacoan peccary (Catagonus wagneri), and collared peccary (Pecari tajacu). Age, parity, litter size, time-since-last-parturition, contraception exposure and type, and lesion prevalence were recorded. Reported chemical contraceptives used in females included porcine zona pellucida vaccine, progestins, GnRH analogues (deslorelin and leuprolide). Average litter size was significantly different between species (p < 0.0001) with the common warthog having the largest average litter size (3.5 ±â€¯0.2 offspring/litter). There was a trend for age to be positively correlated with leiomyoma/sarcomas (r = 0.6135; p = 0.0789). Progestins (medroxyprogesterone acetate, megestrol acetate, depomedroxyprogesterone acetate) were positively correlated (r = 0.8946; p = 0.0161) and GnRH analogues (deslorelin, leuprolide; subcutaneous) were negatively correlated with ovarian cysts (r = 0.9743; p = 0.0010). Across all species, there was a trend for age to be negatively correlated with folliculogenesis (r = -0.6528; p = 0.0566) and parturition gap length to be negatively correlated with follicular cysts (r = -0.8944; p = 0.1). Common warthog, babirusa, and Vietnamese pot-bellied pigs had the greatest diversity of uterine lesions and the highest prevalence of reproductive tract lesions of all species evaluated. Four of the 27 males (14.5%) in the dataset had testicular tumors. All males had prominent testicular interstitial cell populations, which appears to be within normal limits for these species. These data suggest prolonged gaps between pregnancies, age, and contraception are risk factors for reproductive tract lesions in Suidae.

[Human papillomavirus and reproductive health of males].

Human papillomavirus (HPV) infection is one of the most common sexually transmitted diseases (STD) in the world and an important pathogenic factor of male reproductive diseases. A deeper insight into the relationship of HPV with male reproductive health and the characteristics and risk factors of male HPV infection may contribute significantly to the prevention, control and screening of the condition as well as to the improvement of the health of males and of the people in general.

Trends in the Prevalence of Anogenital Warts Among Patients at Sexually Transmitted Disease Clinics-Sexually Transmitted Disease Surveillance Network, United States, 2010-2016.

BACKGROUND: Approximately 90% of genital warts are caused by human papillomavirus (HPV) types 6 and 11. In the United States, HPV vaccination has been recommended for girls and women aged ≤26 years, and since 2011, for boys and men aged ≤21 years and for gay, bisexual, and other men who have sex with men (MSM) aged ≤26 years. METHODS: Data were obtained from 27 clinics participating in the STD Surveillance Network. Trends in the annual prevalence of anogenital warts (AGW) from 2010-2016 were described by sex and by the sex of sex partners. RESULTS: During 2010-2016, significant declines in the prevalence of AGW were observed in women aged <40 years, men who have sex with women only (MSW) aged <40 years, and MSM of all age categories. An inflection in trend in 2012 was noted for MSW aged 20-24 or 25-29 years and for MSM aged 20-24 years. CONCLUSIONS: The observed declines in the prevalence of AGW suggest that HPV morbidity is declining among populations attending STD clinics, including MSW, MSM, and women. Declines in younger age groups are consistent with what would be expected following the implementation of HPV vaccination. However, declines were also observed in older age groups and are not likely to be the result of vaccination.

Incidence, psychosocial burden, and economic impact of genital warts in Mexico / Incidencia, carga psicosocial e impacto económico de las verrugas genitales en México

Abstract: Objective: To estimate the burden of genital warts (GW) in Mexico. Materials and methods: We estimated the annual incidence of GW based on data reported by specialist physicians. We also assessed GW treatment practices, the average cost of treatment, and the psychosocial burden of GW among patients. Results: The annual incidence of GW in Mexico was estimated to be 547 200 cases. Treatment procedures vary by specialist and patient gender. The estimated annual cost was $195 million USD. The psychosocial impact of GW was slightly greater in males than females. Conclusions: This is the first evaluation of the burden of GW in Mexico. Our data suggest that GW are common, with significant health-related costs and psychosocial impact.

Resultados: La incidencia anual de VG en México fue de 547 200 casos. Los tratamientos variaron según la especialidad y el sexo del paciente. El costo anual por VG fue de $195 millones de dólares estadounidenses. El impacto psicosocial de las VG es ligeramente mayor en hombres que en mujeres. Conclusiones: Esta es la primera evaluación de la carga de VG en México. Los datos sugieren que las VG son frecuentes, tienen costos relacionados con salud e impactos psicosociales significativos.

Incidence of external genital lesions related to human papillomavirus among Mexican men. A cohort study / Incidencia de lesiones genitales externas relacionadas con el virus del papiloma humano entre hombres mexicanos. Un estudio de cohorte

Abstract: Objective: To determine external genital lesion (EGL) incidence -condyloma and penile intraepithelial neoplasia (PeIN)- and genital HPV-genotype progression to these EGLs. Materials and methods: Participants (healthy males 18-74y from Cuernavaca, Mexico, recruited 2005-2009, n=954) underwent a questionnaire, anogenital examination, and sample collection every six months; including excision biopsy on suspicious EGL with histological confirmation. Linear array assay PCR characterized 37 high/low-risk HPV-DNA types. EGL incidence and cumulative incidence were calculated, the latter with Kaplan-Meier. Results: EGL incidence was 1.84 (95%CI=1.42-2.39) per 100-person-years (py); 2.9% (95%CI=1.9-4.2) 12-month cumulative EGL. Highest EGL incidence was found in men 18-30 years: 1.99 (95%CI=1.22-3.25) per 100py. Seven subjects had PeIN I-III (four with HPV16). HPV11 most commonly progresses to condyloma (6-month cumulative incidence=44.4%, 95%CI=14.3-137.8). Subjects with high-risk sexual behavior had higher EGL incidence. Conclusion: In Mexico, anogenital HPV infection in men is high and can cause condyloma. Estimation of EGL magnitude and associated healthcare costs is necessary to assess the need for male anti-HPV vaccination.

Resumen: Objetivo: Determinar incidencia de lesiones genitales externas (LGE) -condiloma y neoplasia intraepitelial del pene (NIP)- y progresión de genotipos de VPH a LGE. Material y métodos: Se aplicaron cuestionarios, examen anogenital y recolección de muestras cada seis meses a hombres sanos (18-74 años, de Cuernavaca, México, reclutados 2005-2009, n=954) con biopsia y confirmación histológica. Se caracterizaron 37 tipos de ADN-VPH; se calculó incidencia de LGE (cumulativa con Kaplan-Meier). Resultados: Incidencia de LGE=1.84 (IC95%=1.42-2.39) por 100-persona-años (pa); 2.9% (IC95%=1.9-4.2) LGE acumulativa a 12 meses. Mayor incidencia de LGE entre hombres 18-30 años; 1.99 (IC95%=1.22-3.25) por 100pa. Siete sujetos tuvieron NIP I-III. VPH-11 más comúnmente progresa a condiloma (incidencia acumulativa a seis meses=44.4%, IC95%=14.3-137.8). Los sujetos con comportamiento sexual de alto riesgo tuvieron mayor incidencia de LGE. Conclusiones: En México la infección anogenital con VPH es alta y puede causar condiloma. La estimación de magnitud de LGE y los costos sanitarios asociados se necesita para evaluar la necesidad de vacunación contra VPH en hombres.

Association between male accesory gland infections and prostate cancer in Turkish men: A case-control study.

It is well known that chronic inflammation contributes to several forms of human cancer. Although several studies have investigated the association between prostatitis and prostate cancer, there is a lack of specifically designed study about male accessory gland infections (MAGI) and prostate cancer co-occurrence. We aimed to investigate this association with a case-control study in Turkish men. A total of 155 patients were enrolled to the study. After the pathological examination of the transrectal ultrasound-guided prostate biopsy specimens, patients were divided the two groups as control and prostate cancer and the presence of MAGI was determined. Of 155 patients, 145 met inclusion criteria. In the prostate cancer group, MAGI diagnose was determined in 18 of 31 patients (58.06%), while it was determined in 25 of 114 (21.93%) patients in the control group (p = .001). A significant correlation between MAGI and pathological Gleason score also revealed (p = .0001). We demonstrated that men with MAGI have increased risk for the development of prostate cancer. Moreover, in this population, most of the prostate cancers tend to be clinically significant or high grade.

Spina Bifida Health-care Guidelines for Men's Health.

Spina bifida has traditionally been regarded as a pediatric health issue with little regard to adult consequences of the disorder. The congenital neurologic and urologic anomalies, as well as sequelae of bladder management, can have a profound impact on adult male sexual function. Abnormalities in testicular descent, development, and function; fertility; penile sensation; erectile function; ejaculatory function; and orgasmic function are common. Prostate cancer has been diagnosed in men with spina bifida, but little data are available to guide screening, diagnosis, and treatment efforts. The Spina Bifida Association has supported development of guidelines for health care providers to address male health issues in individuals with spina bifida throughout their lives.

Seven subjects had PeIN I-III (four with HPV16). HPV11 most commonly progresses to condyloma (6-month cumulative incidence=44.4%, 95%CI=14.3-137.8). Subject with high-risk sexual behavior had higher EGL incidence. CONCLUSIONS: In Mexico, anogenital HPV infection in men is high and can cause condyloma. Estimation of EGL magnitude and associated healthcare costs is necessary to assess the need for male anti-HPV vaccination.
