Does SARS-CoV-2 Affect the Prostate? A Molecular Analysis from a Case Series of COVID-19 Patients.

Severe acute respiratory syndrome Coronavirus 2 (SARS-CoV-2) causes COVID-19 that has been spreading worldwide since December 2019. Viral entry into cells requires expression of both angiotensin-converting enzyme 2 (ACE2) and transmembrane protease serine 2 (TMPRSS2) on the surface of the host cell. The male reproductive system, including the prostate, was supposed to be a potential target for SARS-CoV-2 since the presence of ACE and TMPRS2 receptors. This paper investigated for the first time the presence of SARS-CoV-2 mRNA in the prostatic tissue of a patient with active infection. In addition, we searched for the virus in the prostate of five patients after their recovery from COVID-19. The SARS-CoV-2 RNA was not detected in any of the prostate tissues tested even during the acute phase of infection. As case series have limitations, causality cannot be excluded and sporadic evidence of prostatic tissue invasion by SARS-CoV-2 may be detectable.

Factores de riesgo asociados a defectos congénitos de genitales externos y gónadas masculinas

Introducción: Los defectos congénitos del tracto urogenital se encuentran entre las anomalías más encontradas en el feto o neonato, lo que da una idea de su extraordinaria importancia clínica, unido a las escasas investigaciones en la provincia Camagüey, sobre factores de riesgo asociados a los defectos congénitos de genitales externos y gónadas masculinas. Objetivo: Determinar los factores de riesgo asociados a defectos congénitos de genitales externos y gónadas masculinas. Métodos: Se realizó un estudio correlacional del tipo retrospectivo en el Hospital Pediátrico Eduardo Agramonte Piña en el periodo de enero de 2013 a diciembre de 2020. El universo se conformó por los 96 pacientes que fueron intervenidos quirúrgicamente por presentar defectos congénitos de los genitales externos y gónadas masculinas. Para determinar la asociación de los factores de riesgo con la aparición de defectos congénitos se empleó la prueba de independencia, en caso de p<0,05 se consideró asociación significativa. Para medir la magnitud de la asociación estadística entre las variables se utilizó el coeficiente Phi, se consideró mientras más fuerte a uno fuera su valor, más correlacionadas se encontraron las variables estudiadas. Resultados: La criptorquidia fue la forma clínica con mayor número de pacientes, seguida de la hipospadias y la hidrocele. La asociación entre los padres trabajadores agrícolas y la hipospadias y la criptorquidia con padres trabajadores industriales, resultaron significativas. El hecho que la madre fuera fumadora pasiva, constituyó una variable con asociación significativa, tanto para la aparición de hipospadias como de criptorquidia. El ser fumadora pasiva fue el factor de riesgo que tuvo mayor correlación con la aparición de los defectos congénitos. Conclusiones: Existieron factores de riesgo con asociación significativa a la aparición de defectos congénitos de genitales externos y gónadas masculinas.

Introduction: Congenital defects of the urogenital tract are among the anomalies most found in the fetus or neonate, which gives an idea of ​​their extraordinary clinical importance, together with the few investigations in the Camagüey province, on risk factors associated with congenital defects of external genitalia and male gonads. Objective: To determine the risk factors associated with congenital defects of the external genitalia and male gonads. Methods: A retrospective correlational study was carried out at the Eduardo Agramonte Piña Pediatric Hospital from January 2013 to December 2020. The universe was made up of the 96 patients who underwent surgery for presenting congenital defects of the external genitalia and male gonads. To determine the association of the risk factors with the appearance of congenital defects, the independence test was used; in case of p<0.05, a significant association was considered. To measure the magnitude of the statistical association between the variables, the Phi coefficient was used, it was considered that the stronger its value was, the more correlated the studied variables were found. Results: Cryptorchidism was the clinical form with the highest number of patients, followed by hypospadias and hydrocele. The association between farm worker parents and hypospadias and cryptorchidism with industrial worker parents was significant. The fact that the mother was a passive smoker was a variable with a significant association, both for the appearance of hypospadias and cryptorchidism. Being a passive smoker was the risk factor that had the highest correlation with the appearance of birth defects. Conclusions: There were risk factors with a significant association with the appearance of congenital defects of the external genitalia and male gonads.

Characterization of a novel deep-intronic variant in DYNC2H1 identified by whole-exome sequencing in a patient with a lethal form of a short-rib thoracic dysplasia type III.

Biallelic pathogenic variants in DYNC2H1 are the cause of short-rib thoracic dysplasia type III with or without polydactyly (OMIM #613091), a skeletal ciliopathy characterized by thoracic hypoplasia due to short ribs. In this report, we review the case of a patient who was admitted to the Neonatal Intensive Care Unit (NICU) of Indiana University Health (IUH) for respiratory support after experiencing respiratory distress secondary to a small, narrow chest causing restrictive lung disease. Additional phenotypic features include postaxial polydactyly, short proximal long bones, and ambiguous genitalia were noted. Exome sequencing (ES) revealed a maternally inherited likely pathogenic variant c.10322C > T p.(Leu3448Pro) in the DYNC2H1 gene. However, there was no variant found on the paternal allele. Microarray analysis to detect deletion or duplication in DYNC2H1 was normal. Therefore, there was insufficient evidence to establish a molecular diagnosis. To further explore the data and perform additional investigations, the patient was subsequently enrolled in the Undiagnosed Rare Disease Clinic (URDC) at Indiana University School of Medicine (IUSM). The investigators at the URDC performed a reanalysis of the ES raw data, which revealed a paternally inherited DYNC2H1 deep-intronic variant c.10606-14A > G predicted to create a strong cryptic acceptor splice site. Additionally, the RNA sequencing of fibroblasts demonstrated partial intron retention predicted to cause a premature stop codon and nonsense-mediated mRNA decay (NMD). Droplet digital RT-PCR (RT-ddPCR) showed a drastic reduction by 74% of DYNCH2H1 mRNA levels. As a result, the intronic variant was subsequently reclassified as likely pathogenic resulting in a definitive clinical and genetic diagnosis for this patient. Reanalysis of ES and fibroblast mRNA experiments confirmed the pathogenicity of the splicing variants to supplement critical information not revealed in original ES or CMA reports. The NICU and URDC collaboration ended the diagnostic odyssey for this family; furthermore, its importance is emphasized by the possibility of prenatally diagnosing the mother's current pregnancy.

Male Genital Self-Image Scale (MGSIS): Cutoff Point, Cultural Adaptation and Validation of Measurement Properties in Brazilian Men.

BACKGROUND: Concerns about genital self-image (GSI) can influence sexual function and quality of life, and instruments that assess male GSI, such as the Male Genital Self-Image Scale (MGSIS), need to be adapted and validated in different cultures. AIMS: To culturally adapt and validate the measurement properties of MGSIS in Brazilian men, according to the COnsensus-based Standards for the selection of health Measurement INstruments (COSMIN) guideline, and to create a cutoff point for satisfaction with male GSI. METHODS: We assessed the validity of content through a committee of experts and cognitive interviews. The internal consistency and test-retest reliability were assessed using Cronbach's α and Intraclass Correlation Coefficient (ICC). We also calculate measurement errors using the Bland and Altman graph. The structural validity was investigated through exploratory and confirmatory factor analysis. The hypothesis test for construct validity was assessed using Spearman correlation from MGSIS with the International Index of Erectile Function (IIEF), Body Appreciation Scale (BAS-2) and Rosenberg Self-Esteem Scale (RSES). To create a cutoff point for satisfaction with the GSI, the item response theory and the classic test theory were used. OUTCOMES: Male's (i) GSI, (ii) sexual function, (iii) body appreciation, and (iv) self-esteem were assessed. RESULTS: In this study, 518 men with a mean age of 33.90 (±13.83) years participated. The Brazilian version of MGSIS demonstrated good content validity and a single factor that explained 64.57% of the variance. Cronbach's α and ICC values were 0.905 and 0.806, respectively. By assessing measurement errors, we found no systematic bias in the sample. MGSIS showed a moderate to weak correlation with IIEF, BAS-2 and RSES. A cut-off point of 23 in the MGSIS total score was found to rate satisfaction with the GSI. CLINICAL TRANSLATION: MGSIS is a valid and reliable measurement instrument for measuring male GSI in Brazil. STRENGTHS AND LIMITATIONS: This study evaluated the measurement properties of MGSIS according to COSMIN, which is a powerful and useful guideline for measurement properties. However, due to the lack of a gold standard for measuring the GSI, we have not assessed the criterion validity. CONCLUSION: MGSIS is valid, reliable and can be useful to assess the GSI and classify the satisfaction with the GSI of Brazilian men. de Arruda GT, da Silva EV, Braz MM.

Streptococcus agalactiae and genital ulcers in a heterosexual male / Streptoccoccus agalactiae y úlceras genitales en un varón heterosexual

Streptococcus agalactiae (S. agalactiae) is a microorganism that asymptomatically colonizes the female genital and gastrointestinal tracts of humans. It produces infections in extreme ages of life and in pregnant women. The case of an adult male is presented, with frequent heterosexual intercourse with different partners. He consulted for itching and burning in the penis' glans. His partner had marked vaginal dryness as a result of early ovarian failure. The patient had ulcerative, non-painful, erythematous lesions with raised edges and little yellow-green discharge. No Donovan bodies were found in the discharge smear and the culture was positive for S. agalactiae. His asymptomatic partner had negative microbiological tests. Both with negative serologies for Chlamydia, HIV and syphilis. No information was obtained from other sexual contacts. It cannot be ascertained that it was a venereal event, it is more likely that the injuries are related to repeated coital trauma.(AU)

Streptococcus agalactiae (S. agalactiae) es un microorganismo que coloniza asintomáticamente el tracto genital y gastrointestinal femenino de los seres humanos. Produce infecciones en edades extremas de la vida y en mujeres embarazadas. Se presenta el caso de un varón adulto, con frecuentes relaciones heterosexuales con diferentes parejas. Consultó por picazón y ardor en el glande del pene. Su pareja tenía una sequedad vaginal marcada como resultado de una insuficiencia ovárica precoz. El paciente presentaba lesiones ulcerosas, eritematosas, indoloras, con bordes elevados y escasa secreción de color amarillo verdoso. No se encontraron cuerpos de Donovan en el frotis de descarga y el cultivo fue positivo para S. agalactiae. Su pareja asintomática tuvo pruebas microbiológicas negativas. Ambos con serologías negativas para clamidia, VIH y sífilis. No se obtuvo información de otros contactos sexuales. No se puede determinar que fue un evento venéreo, es más probable que las lesiones estén relacionadas con traumatismos coitales repetidos. (AU)

Basal Cell Carcinoma of the External Genitalia: A Population-Based Analysis.

INTRODUCTION: Basal cell carcinoma (BCC) located on the genitalia is rare; data on the clinicopathologic features and survival outcomes are only available through case reports and small case series studies. PURPOSE: This study aimed to explore the epidemiology and identify the prognostic factors of genital BCCs. METHODS: We queried the 18 registries of the Surveillance, Epidemiology, and End Results database for patients with primary BCCs of the genital skin from 2000 through 2017. The primary endpoint was overall survival (OS) and disease specific survival (DSS). Kaplan-Meier survival analysis was conducted to assess the impact of clinicopathological variables on OS and DSS. Multivariate Cox proportional hazards model was performed to evaluate risk factors for OS. RESULTS: A total of 1,607 cases of genital BCCs were identified. The cohort was composed of 1,352 women (84.1%) and 255 men (15.9%). The median (P25, P75) age of the entire cohort was 73(63-82)years. White patients accounted for 87.2% of the cases. For women and men, the most common site of involvement was the labia majora (89.6%) and scrotum (74.5%), respectively. The majority of patients with genital BCC had localized disease (75.5%). Kaplan-Meier survival analysis showed that female genital BCCs experienced better DSS than men (209.1 months vs 194.8 months); for men, BCCs located on the scrotum had better DSS and OS than those on the penis (P < 0.05 for both endpoints). All patients with distant disease died of disease-specific death, and the average survival time was 8.2 months. Multivariate analysis revealed that age, primary site, and stage were independent determinants of OS for men, while tumor size, histologic subtype, and race were not. For women, factors associated with worse OS included increasing age, tumor size more than 2 cm, and distant disease; factors associated with a decreased risk included "other" and "unknown" races. CONCLUSION: The prognosis of genital BCCs is excellent, while the survival of distant disease is very poor. Despite similar clinicopathologic features and overall survival outcomes, men and women should be treated as two different entities when making survival predictions.

Asian herminiine moths of the Herminia decipiens complex are revised and five allopatric species are recognized, i.e. Herminia decipiens (Hampson, 1898) in Nilgiri Hills, Khasi Hills, South China, Indochina, Malay Peninsula, H. terminalis (Wileman, 1915) in Taiwan, H. yuksam sp. nov. in East Nepal, Sikkim, H. borneo sp. nov. in Borneo and H. amamioshima sp. nov. in Amami-oshima Is., Shimo-Koshikijima Is. and South Kyushu (Kagoshima). Key to all species is given.

A semiautomated whole-exome sequencing workflow leads to increased diagnostic yield and identification of novel candidate variants.

Advancing the clinical utility of whole-exome sequencing (WES) for patients with suspected genetic disorders is largely driven by bioinformatics approaches that streamline data processing and analysis. Herein, we describe our experience with implementing a semiautomated and phenotype-driven WES diagnostic workflow, incorporating both the DRAGEN pipeline and the Exomiser variant prioritization tool, at an academic children's hospital with an ethnically diverse pediatric patient population. We achieved a 41% molecular diagnostic rate for 66 duo-, quad-, or trio-WES cases, and 28% for 40 singleton-WES cases. Preliminary results were returned to ordering physicians within 1 wk for 12 of 38 (32%) probands with positive findings, which were instrumental in guiding the appropriate clinical management for a variety of patients, especially in critical care settings. The semiautomated and streamlined WES workflow also enabled us to identify novel variants in candidate disease genes in patients with developmental delay and autism and immune disorders and cancer, including ANK2, BPTF, BCL11A, FOXN1, PLAA, ATRX, DNAJC21, and RAD50 Together, we demonstrated the implementation of a streamlined WES workflow that was successfully applied for both clinical and research purposes.

Case for diagnosis. Atypical genital lesion

Abstract: We present a case of a penile lesion with a clinical appearance similar to Mondor penile disease (thrombosis of the dorsal vein of the penis) or penile sclerosing lymphangitis. Laboratory evaluation, however, showed a solid lesion, with no vascular component to Doppler ultrasonography and no treponema to immunohistochemistry. Histological and serological tests were compatible with secondary syphilis. The authors reinforce the need for the inclusion of syphilis in the differential diagnosis of penile cord injuries.

A wet dressing for male genital surgery: A phase II clinical trial

ABSTRACT Purpose: This study was to confirm the safety and efficacy of BC dressing when used in surgical male wound healing at the urogenital area. Methods: Open, non-controlled clinical study of phase II. A total of 141 patients, among those children, adolescents and adults with hypospadias (112), epispadias (04), phymosis (13) and Peyronie's disease (12) that had a BC dressing applied over the operated area after surgery. A written informed consent was obtained from all participants. Study exclusion criteria were patients with other alternative treatment indications due to the severity, extent of the injury or the underlying disease. The outcomes evaluated were efficacy, safe and complete healing. The costs were discussed. Results: In 68% patients, the BC dressing fell off spontaneously. The BC was removed without complications in 13% of patients at the outpatient clinic during the follow-up visit and 17% not reported the time of removal. In 3% of the cases, the dressing fell off early. Complete healing was observed between 8th and 10th days after surgery. The BC dressings have shown a good tolerance by all the patients and there were no reports of serious adverse events. Conclusion: The bacterial cellulose dressings have shown efficacy, safety and that can be considered as a satisfactory alternative for postoperative wound healing in urogenital area and with low cost.

Primary cutaneous histoplasmosis developed in the penis of an immunocompetent patient

A 70-year-old male presenting a 3-month history of genital painless erythematous nodules in the balanopreputial sulcus was referred to our service. Histopathological exam presented a chronic dermatitis with epithelioid granulomas and Grocott staining revealed numerous fungal structures with a suggestive morphology of Histoplasma sp. Cultures evidenced Histoplasma capsulatum var. capsulatum. Treatment with oral itraconazole led to complete remission of lesions.

Fratura de pênis com trauma uretra / Penile fracture with urethral trauma

We reported a case of a twenty-nine-year-old male who presented a penile fracture associated with urethral injury caused by a sexual intercourse. An ideal anamnesis and a special physical examination were determinant to correct diagnostics. Ultrasonography and uretrocistography must be performed for confirmation. The treatment is based on the presence of associated urethral injury. The surgical repair of cavernous body and urethra can produce good results, with a favorable prognosis and minimal rate of complications.

Familial testicular torsion: a meta analysis suggests inheritance.

OBJECTIVE: Familial occurrence of testicular torsion has been infrequently reported. To date, no systematic analysis has been published. We systematically analyzed the literature to elucidate the epidemiology, presentation, management, and whether the observed prevalence of testicular torsion in families is consistent with absence of inheritance and is randomly distributed. PATIENTS AND METHODS: We searched electronic databases using keywords "testicular torsion", "spermatic cord torsion", "familial torsion" and "sibling torsion". Reports with genetically related first degree relatives were included in the analysis. Levene's nonparametric test was used to compare the variance of the age of presentation within families to that between different families to differentiate between familial predisposition and chance events. RESULTS: Up to 10% of patients with testicular torsion have an affected first degree relative. We were able to reject the null hypothesis that the observed prevalence of testicular torsion is due to chance (p < 0.001). Family history is missed in at least 27% of affected families. There is a high incidence of bilateral testicular torsion in families (37%) and probands (17%) and a high concordance rate for bilaterality among monozygous twins. CONCLUSIONS: Current evidence from clinical and animal studies suggests the presence of a genetically determined component in familiar testicular torsion. Increased awareness may lead to earlier clinical presentation and higher testicular salvage rates.

Plástica do púbis e da genitália externa: duas décadas de experiência / Plastic of the pubis and external genitalia: two decades of experience

Este artigo registra a experiência de duas décadas de cirurgias realizadas na região do púbis e da genitália externa em pacientes de ambos os sexos. A literatura apresenta limitadas contribuições sobre as alterações morfológicas que têm levado seus portadores a se submeterem a cirurgias para retornarem à normalidade anatômica, ao equilíbrio emocional e a recuperarem a autoestima. Método: Foram operados 513 pacientes com diferentes tipos de patologias nos genitais externos e no púbis, num período de vinte anos, sendo 469 (91,42%) do sexo feminino e 44(8,58%) do sexo masculino. A idade variou de 17 a 70 anos. No sexo feminino, as deformidades mais frequentes foram as distrofias do púbis, grandes e pequenos lábios, prepúcio sobre o clitóris, além das distorções secundárias decorrentes de cirurgias realizadas previamente nestas regiões. No sexo masculino, as afecções mais frequentes envolveram a região pubiana, hipotrofias penianas, sinéquias e ausência de testículos. Deformidades congênitas, além das descritas, não foram incluídas no presente artigo. Resultados: Durante o período de 1989 a 2010, os procedimentos aplicados nas disformias pubianas e nas genitálias beneficiaram pacientes física e psicologicamente, pela qualidade dos resultados e pelo baixo índice de complicações (2,31%). Conclusões: Apesar da limitada divulgação científica nas revistas da especialidade e nos eventos científicos, a importância destas patologias não tem limite nos seus portadores. Uma das razões da presente publicação baseia-se na experiência adquirida e a necessária divulgação aos especialistas que realizam estas cirurgias, face às consequências que determinam quando não executadas dentro da necessária realidade.

This article is the result of two decades of surgical experience in the pubic region for patients of both genders with the external genitalia dimorphic aspects. The literature presents limited contributions regarding the morphologic alterations of these regions, responsible for the patients be submitted to these surgeries to return to their normal anatomic aspects, to the emotional equilibrium and to the self-esteem. Methods: Patients of both genders, in a total of 513, with different types of pathologies of the external genitalia and the pubic regions were submitted to specific surgeries, where 469 (91.42%) were female and 44 (8.58%) were male. The age range was from 17 to 70 year old. In the female patients were included: dystrophies of the pubis, labia majora and minora, skin excess of the clitoris, and the treatment of other types of unacceptable results after previous surgical procedures. The male deformities included in this study were: penis hypotrophy, skin penis synechia, local angioma and the absence of congenital testicular glands. Congenital or acquired deformities out of the described were not included. Results: From 1989 to 2010, the procedures used in the genitalia and in the pubis dimorphisms brought psychological and physic benefic to the patients combined with low complication rate (2.31%). Conclusions: Despite of the limited scientific publications in the journals of the specialty and in the scientific meetings, the importance of these messages has no limits to their holders. One of reasons of this publicationis based in acquired experience and the necessary diffusion for those that perform these surgeries but still with negative results when not performed within the necessary level.

Investigation of male urinogenital clue cell and its relationship with male infertility / 中国医师杂志

Objective To investigate the relationship between clue cell in semen and male infertility. Method Semen specimens from 957 patients were examined with microscope. Gram staining was performed when clue cell were found to be present in semen. At the same time, general characteristics of the sperm were analyzed. Results There were clue cells in 23. 5% (225/957) of the total specimens, in which, 95. 1% clue cells were gram staining positive. The concentration and vitality of living sperm in semen presented with clue cell were significantly lower, but the abnormal sperm and pH value were much higher than that in normal control (P<0.01). In addition, 28 sexual partners of 30 infertility patients were identified as having bacterial vaginosis. Conclusion Gardnerella vaginalis and short coccohacillus were mostly transmitted from infected sexual partner. It could cause squamous epithelial cell forming clue cell, and lead to infertility by chan-ging pH which mainly affect reproduction of the sperm. This study suggested that clue cell has a unique vale for the diagnosis of infertility causing by Gardnerella vaginalis and short coccohacillus.

Prevalence of genital chlamydia in Iranian males with urethritis attending clinics in Mashhad

Chlamydia trachomatis is a common cause of sexually transmitted disease which can cause severe consequences. Effective prevention requires knowledge of prevalence of infection in order to target interventions in a cost-effective manner. To determine the prevalence of chlamydial infection in Mashhad, northeastern Islamic Republic of Iran, this study was performed among male patients with urethritis. Urethral discharge was collected from 150 patients. Cell culture was established for diagnosis of Chlamydia in genital specimens. Cell culture showed that 9.3% of patients in this study were infected with Chlamydia. This study provides strong evidence that prevalence of Chlamydia in our region is quite high, which necessitates screening and treatment for the infection

Time trends in biological fertility in Britain.

BACKGROUND: There is evidence of a decline in semen quality in some countries, including Britain, in recent decades. This retrospective cohort study examined the hypothesis that biological fertility had also declined. The trend in couple fertility was assessed by means of time to pregnancy (TTP--a sensitive and validated measure of fertility. METHODS: A representative sample of the British population aged 16-59 years was surveyed. TTP was obtained for all births conceived after unprotected intercourse that began during 1961-93, excluding contraceptive failures. The sample size was 1540. FINDINGS: In contrast to the original hypothesis, this study found that fertility has increased; the rising trend was accompanied by slight dips during 1976-80 and 1986-90. These results were consistent between male and female respondents, and undiminished by adjustment for possible confounding factors. A stronger and more consistent relation was found with the year when unprotected intercourse started (a period effect) than with the year of birth of either partner (a birth cohort effect). INTERPRETATION: The findings could not be explained by trends in age at first birth, increased treatment of subfertility, or changes in oral contraceptive use. If a decline in male fertility has occurred, it has been more than compensated for by a countervailing increase in couple fertility.

Sildenafil (Viagra) in the treatment of male erectile dysfunction in Nairobi.

OBJECTIVE: To evaluate the effectiveness of sildenafil (Viagra) in the treatment of male erectile dysfunction in Nairobi. DESIGN: Prospective open label extension study. SETTING: Urology clinics at the Nairobi Hospital, Kenyatta National Hospital and the author's private clinic in Hurlingham, Nairobi. PARTICIPANTS: Two hundred and nineteen adult male patients with erectile dysfunction. RESULTS: The age range was 33-80 years with a mean of 62.5 years and a peak incidence in the 60-69 year age group. One hundred and nineteen patients (54.34%) had organic causes, 85 patients (38.81%) had psychogenic causes and 15 patients had mixed causes. Two hundred patients (91.32%) had improved sexual function after treatment with viagra. This improvement was sustained during the study period of sixteen weeks and included improved erectile and orgasmic functions and overall sexual satisfaction. One hundred and fifty seven of these patients responded to therapy with 50 mg of viagra; 40 patients with 25 mg and three patients with 100 mg of therapy. Nineteen patients (8.68%) had no improvement in sexual function after viagra administration. Seven patients (3.2%) had adverse effects which were mild and transient. They included mild headaches in three patients, mild dyspepsia in two patients and facial flushing and nausea and vomiting in one patient, respectively. CONCLUSION: Oral sildenafil (Viagra) is an effective well tolerated and simple treatment for male erectile dysfunction in the majority of cases. The cost of treatment at about ten United States dollars for the 50 mg tablet is prohibitive and may limit its wide use by many deserving patients in this locality.

PIP: This prospective open-label extension study was carried out to evaluate the effectiveness of sildenafil (Viagra) in the treatment of male erectile dysfunction in Nairobi, Kenya. A total of 219 adult male patients with erectile dysfunction were instructed to take 50 mg, 25 mg, or 100 mg of sildenafil orally 1 hour prior to planned sexual activity, but not more than once every 24 hours. Patients were reviewed at 4-week intervals for 16 weeks to assess the efficacy and adverse effects of the drug. The age range was 33-80 years with a mean of 62.5 years and a peak incidence in the 60-69 year age group. The causes of erectile dysfunction were organic (n = 119, 54.34%), psychogenic (n = 85, 38.81%), and mixed (n = 15). 200 patients (91.32%) had improved sexual function after treatment with Viagra. This improvement included improved erectile and orgasmic functions and overall sexual satisfaction. 157 patients responded to the 50-mg treatment regimen; 40, to the 25-mg regimen; and 3, to the 100-mg regimen. No improvement in sexual function was reported in 19 patients (8.68%) after Viagra administration. In addition, 7 patients reported mild and transient adverse effects of the drug, including mild headache, dyspepsia, facial flushing, nausea, and vomiting. In conclusion, oral sildenafil (Viagra) is an effective well-tolerated and simple treatment for male erectile dysfunction in the majority of cases. However, the cost of treatment may prohibit and limit its wide use by many deserving patients in this area.
