Trends in vasectomy and sexually transmitted diseases in Chile: findings from robust national databases / Tendencias de la vasectomía y las enfermedades de transmisión sexual en Chile: resultados de bases de datos robustas / Tendências em vasectomia e doenças sexualmente transmissíveis no Chile: resultados de bases de dados robustas

Abstract: A controversy about the increase or decline of vasectomy is emerging; however, the evidence is still scarce in Latin America. This ecological study analyzed the vasectomy and sexual transmitted diseases (STD) trends over a period of 10 years in Chile and determined if there is any relationship between them. We conducted a mixed ecological study using secondary and representative data on the number of vasectomies and STD cases from 2008 to 2017. Vasectomy rates were calculated for age-specific groups of men aged 20-59 years, and specific STD (HIV, chlamydia, gonorrhea, trichomoniasis, and syphilis) for the same period. Multivariate negative binomial regression models were fitted to evaluate rate trends and relationships. The mean vasectomy age was 40.3 years, with no significant differences between the years of the study (p = 0.058). The overall vasectomy rate significantly increased from 2008 to 2017 (p < 0.001), with differences between age groups (p < 0.001). The most significant increase was observed in men aged 30-49 (p < 0.001). The STD rates significantly increased (p < 0.05) during the study period. A significant positive correlation was found between vasectomy and gonorrhea incidence rates (p = 0.008) and an inverse correlation was found with hepatitis B incidence rates (p = 0.002). Vasectomy trends and STD rates significantly increased from 2018 to 2017 in Chile. especially among men aged 30-49 years. The relationship between vasectomy and STD increments suggests a new risk factor for reproductive and sexual health policies to aid controlling the HIV and STD epidemic.

Resumen: Se viene surgiendo una controversia sobre el aumento o la disminución de la vasectomía; sin embargo, la evidencia aún es escasa en América Latina. Este estudio ecológico analizó las tendencias de la vasectomía y las enfermedades de transmisión sexual (ETS) durante un período de 10 años en Chile y determinó si existe alguna relación entre ellas. Este es un estudio ecológico mixto que utiliza datos secundarios representativos sobre el número de vasectomías y casos de ETS de 2008 a 2017. Las tasas de vasectomía se calcularon por grupos de edad teniendo en cuenta a hombres entre 20-59 años de edad y ETS específicas (VIH, clamidia, gonorrea, tricomoniasis y sífilis) para el mismo período. Los modelos de regresión binomial negativa multivariante se ajustaron para evaluar las tendencias y las relaciones entre las tasas. La edad media de la vasectomía fue de 40,3 años, sin diferencias significativas entre el período del estudio (p = 0,058). La tasa general de vasectomía tuvo un incremento significativo para el período de 2008 a 2017 (p < 0,001), con diferencias entre los grupos de edad (p < 0,001). El incremento más significativo se observó en hombres de entre 30-49 años (p < 0,001). Las tasas de ETS tuvieron una alza significativa (p < 0,05) durante el período de estudio. Hubo una correlación positiva significativa entre las tasas de vasectomía y las tasas de incidencia de gonorrea (p = 0,008) y una correlación inversa con las tasas de incidencia de hepatitis B (p = 0,002). Se concluye que las tendencias de la vasectomía y las tasas de ETS presentaron un incremento significativo en período de 2008 a 2017 en Chile, especialmente entre los hombres de entre 30-49 años. La relación entre la vasectomía y el incremento de las ETS puede ser un nuevo factor de riesgo para las políticas de salud sexual y reproductiva que puede ayudar a controlar la epidemia del VIH y las ETS.

Resumo: Uma controvérsia sobre o aumento ou declínio da vasectomia está surgindo; no entanto, as evidências ainda são escassas na América Latina. Este estudo ecológico analisou as tendências de vasectomia e doenças sexualmente transmissíveis (DST) em um período de dez anos no Chile e determinou se há alguma relação entre elas. Este é um estudo ecológico misto utilizando dados secundários e representativos sobre o número de vasectomias e casos de DSTs de 2008 a 2017. As taxas de vasectomia foram calculadas por grupos etários, considerando homens de 20-59 anos de idade e DSTs específicas (HIV, clamídia, gonorreia, tricomoníase e sífilis) para o mesmo período. Modelos de regressão binomial negativa multivariada foram ajustados para avaliar tendências e relações entre taxas. A média de idade da vasectomia foi de 40,3 anos, sem diferenças significativas entre os anos do estudo (p = 0,058). A taxa geral de vasectomia aumentou significativamente de 2008 a 2017 (p < 0,001), com diferenças entre grupos etários (p < 0,001). O aumento mais significativo foi observado em homens de 30-49 anos (p < 0,001). As taxas de DST aumentaram significativamente (p < 0,05) durante o período de estudo. Houve correlação positiva significativa entre as taxas de vasectomia e as taxas de incidência de gonorreia (p = 0,008) e uma correlação inversa com as taxas de incidência de hepatite B (p = 0,002). As tendências de vasectomia e as taxas de DST aumentaram significativamente de 2008 para 2017 no Chile, especialmente entre homens de 30-49 anos. A relação entre vasectomia e incrementos de DST sugere um novo fator de risco para políticas de saúde sexual e reprodutiva para auxiliar no controle da epidemia de HIV e DST.

Risk of post-vasectomy infections in 133,044 vasectomies from four international vasectomy practices

ABSTRACT Objectives: To estimate the risk of post-vasectomy infections in various settings and across various surgical techniques and sanitization practices. Patients and Methods: Retrospective review of the records of 133,044 vasectomized patients from four large practices/network of practices using the no-scalpel vasectomy (NSV) technique in Canada (2011-2021), Colombia (2015-2020), New Zealand (2018-2021), and the United Kingdom (2006-2019). We defined infection as any mention in medical records of any antibiotics prescribed for a genital or urinary condition following vasectomy. Results: Post-vasectomy infection risks were 0.8% (219 infections/26,809 procedures), 2.1% (390/18,490), 1.0% (100/10,506), and 1.3% (1,007/77,239) in Canada, Colombia, New Zealand, and the UK, respectively. Audit period comparison suggests a limited effect on the risk of infection of excising a short vas segment, applying topical antibiotic on scrotal opening, wearing a surgical mask in Canada, type of skin disinfectant, and use of non-sterile gloves in New Zealand. Risk of infection was lower in Colombia when mucosal cautery and fascial interposition [FI] were used for vas occlusion compared to ligation, excision, and FI (0.9% vs. 2.1%, p<0.00001). Low level of infection certainty in 56% to 60% of patients who received antibiotics indicates that the true risk might be overestimated. Lack of information in medical records and patients not consulting their vasectomy providers might have led to underestimation of the risk. Conclusion: Risk of infection after vasectomy is low, about 1%, among international high-volume vasectomy practices performing NSV and various occlusion techniques. Apart from vasectomy occlusion technique, no other factor modified the risk of post-vasectomy infection.

Vasectomy reversal in China during the recent decade: insights from a multicenter retrospective investigation / 亚洲男科学杂志(英文版)

To date, there is little information about the demography of vasectomy reversal (VR) patients or the factors currently influencing VR effectiveness in China, especially after the universal two-child policy was released in 2015. In this research, demographic data and perioperative medical records of VR patients were extracted from seven major hospitals in different provinces or municipalities of China. Meanwhile, a telephone survey of the patients was conducted to collect follow-up information. Eventually, 448 VR cases from the past 13 years were included. The results were analyzed by stratified comparison to investigate factors that can influence postoperative vas deferens patency and pregnancy rate. Appropriately statistical methods were used, and all of the protocols were approved by the Ethics Committees of the institutes in this research. The results showed that the annual operation volume of VR quadrupled after the two-child policy was implemented. Nonmicrosurgery and a long duration of vasectomy were significantly associated with a lower patency rate. A follow-up survey showed that the general postoperative pregnancy rate was 27.2%. For female partners over the age of 35 years, the postoperative pregnancy rate showed a more severe decline, but only 35.5% of them had been given a fertility examination before their husbands' VR surgery. Our work revealed that more patients in China have been demanding VR in recent years. High-quality microsurgery and a short duration of vasectomy are crucial for restoring patency by VR. Clinical andrologists should perform a preoperative fertility evaluation of the patients' female partners.

Vasectomy re-reversal: effectiveness and parameters associated with its success

ABSTRACT Introduction: When the vasectomy reversal (VR) fails, and the patient desires natural conception with his sperm, vasectomy re-reversal (VRR) is the only alternative. Purpose: To determine the VRR effectiveness and whether specific parameters can be associated with its success. Materials and Methods: We retrospectively evaluated 18 consecutive vasectomized patients, who had failed their VR through bilateral vasovasostomy, and posteriorly were submitted to VRR. The parameters of the study were: age of the patients, elapsed time between vasectomy and VRR (V-VRRt), elapsed time between VR and VRR (VR-VRRt), presence of spermatozoa in the proximal vas deferens fluid (SptzVDF) in the VRR and results of semen analysis after VRR (SA-VRR). Results: The mean of the age of the patients was 44.11±6.55 years (32.0-57.0), the mean of V-VRRt was 11.76±6.46 years (1.5-25.0) and the mean of VR-VRRt was 2.13±2.27 years (0.5-10.0). SptzVDF in the VRR were found bilaterally in 8 patients, unilaterally in 4 and absent in 6. SA-VRR demonstrated normozoospermia in 9 patients, oligozoospermia in 3 and azoospermia in 6, with patency rate of 66.67%. SA-VRR showed statistically significant dependence only with SptzVDF in the VRR (p <0.01). Conclusions: VRR was effective in restoring the obstruction in more than half of the patients. Furthermore, the presence of spermatozoa in the vas deferens fluid was the parameter associated with the VRR success.

Role of Chemical Vasectomy by using Various Chemical Agents as a Method of Male Sterilisation

Introduction: Chemical vasectomy being a non-surgicalprocedure is safe, convenient and functionally reliable, havingfewer complications in comparison to surgical vasectomy.Therefore aim of present study was to develop a simple nonsurgical technique of male sterility which consists of injectionof chemical agents, sclerosant, inducing the obstruction ofvas, through the skin of the scrotum directly.Material and Methods: Present clinical study was carriedout on the cases of benign hyperplasia of prostate, admitted insurgical wards of L.L.R Hospital, Kanpur for Prostatectomyduring the period of August 1982 to June 1983. Forty fivepatients were classified in 3 equal groups by using threedifferent chemical agents.Results: Best results were achieved with 0.2ml, since itobliterated about 1 cm of vas in each case sufficient length tobring about satisfactory obliteration. Quantity more than 0.2ml up to 0.3 ml was useful but more than 0.3 ml was not ableto obliterate length of vas in proportion to quantity.Conclusion: Best chemical appears to be 95% ethanolhaving better results than other two chemical agents and leastcomplications were observed with 95% ethanol.

A cross-sectional study on preference of tubectomy over vasectomy among eligible couples in Bengaluru, Karnataka

Background: Population policies, family planning and welfare programmes undertaken by the Government of India, have led to continuous decrease in the fertility rate but sustainability and target of net reproduction rate 1 is not yet achieved. With increase trend of adopting the permanent method of contraception by eligible couples, the preferences of tubectomy over vasectomy is still remarkable. Hence, the present study is taken up to find Knowledge, Attitude and Practice regarding sterilization and factors influencing it.Methods: A cross-sectional study is conducted in the year 2017 among eligible couples who have completed their family size or pregnant women who came for second confinement to Vydehi Institute of Medical Sciences and Research Centre and Shreyas Maternity Home, Hoskote and Shreyas maternity home are included. An institutional ethics committee (IEC) is given on vasectomy, the better method of sterilization and responses are recorded.Results: A total 92.6% couples were aware of permanent family planning methods. Among them only 30.6% couples are aware of vasectomy. There is a significant association between number of children in a family and to undergo sterilization (p=0.02) method. Reason for not choosing vasectomy are unawareness (49.3%) and social stigma (38%) mainly. 11 couples (7.3%) changed their opinion to undergo vasectomy after giving an IEC.Conclusions: Many couples were knowledgeable about tubectomies and opted for it. Only a small number of couples changed their opinion from tubectomy to vasectomy after being given an IEC.

Knowledge and Acceptance towards Vasectomy in a Sample of Medicine Students, Meta 2018 / Conocimientos y aceptación sobre vasectomía en una muestra de estudiantes de medicina, Meta 2018

Introduction The low adherence to vasectomy is associated with the cultural environment, with false beliefs, and with lack of knowledge. In Colombia, the practice of vasectomy increased 3% between 1990 and 2015. Medical education seeks to have an impact on the general population; therefore, medicine students should have knowledge and attitudes toward birth control that include a significant participation of the male gender. Objective To describe the level of knowledge, beliefs, and acceptance of vasectomy in a sample of Colombian medicine students. Methods Cross-sectional descriptive study, nonprobabilistic sample by convenience with a total of 112 medicine students from different universities of the country attending at a university event. A total of 20 dichotomous questions were used. Results A total of 72.3% of the students answered correctly most of the answers; the knowledge level was grouped in high (53.35%), medium (41.07%), and low (5.35%). Up to 95.5% of the students recognized vasectomy as a male birth control method. Regarding beliefs, > 99% considered that family planning is not just a responsibility of women, although only 75% of the men would accept undergo a vasectomy. Conclusions Colombian medicine students have a good level of knowledge about vasectomy, they recommend performing the surgery, and recognize the active participation of males in contraception; nevertheless, a higher willingness to perform a vasectomy would be expected from this population. Training on the subject would break barriers about beliefs and promote proper counseling in birth control consultations.

Introducción La poca adherencia a la vasectomía se asocia al entorno cultural, falsas creencias y bajo conocimiento. En Colombia, su prevalencia incrementó 3% entre los años 1990 y 2015. La educación Médica busca tener impacto sobre la población general, por lo cual el estudiante de medicina debe tener conocimientos y actitudes sobre la planificación familiar, que incluya una participación significativa del sexo masculino. Objetivo Describir el nivel de conocimiento, creencias y aceptación de la vasectomía en una muestra de estudiantes de medicina colombianos. Métodos Estudio descriptivo transversal, muestra no probabilista por conveniencia de 112 estudiantes de medicina, de diferentes universidades del país asistentes a un evento universitario. Se emplea instrumento de 20 preguntas dicotómicas. Resultados El 72,3% de los estudiantes acertó correctamente en la mayoría de las respuestas, se agrupó nivel de conocimiento en alto 53,35%, medio 41,07% y bajo 5,35%. Hasta un 95,5% reconoció la vasectomía como método de planificación masculina. En cuanto a creencias, más del 99% manifiesta que la planificación familiar no es responsabilidad solo de la mujer, aunque sólo el 75% de los hombres aceptó realizarse la vasectomía. Conclusiones Los estudiantes de medicina colombianos tienen un buen nivel de conocimientos sobre vasectomía, recomiendan su realización y reconocen la participación activa masculina dentro de la anticoncepción, sin embargo, se esperaría una mayor disposición, por parte de esta población, a la realización de la vasectomía. La capacitación sobre el tema puede romper las barreras de creencias y promover un adecuado asesoramiento en las consultas de planificación familiar.

The effect of counseling and family planning education on Knowledge and attitude of comorbid families

To improve the comorbid families behavior, knowledge, and attitudes about evidencebased options, we undertook an educational intervention. In current study, we evaluated the knowledge and attitude of the comorbid families about family planning option s pre and post informing program. the knowledge and attitudes of the comorbid families about family planning options pre and post educational intervention, from Feb -2015 to April-2016. This is a pre-post intervention survey analysis of seventy-six monogamous married couples. Couples were sequentially enrolled if they met inclusion criteria of harboring comorbidities when seeking family planning services. we evaluated the participants by using a questionnaire based on health belief model prior to and fo llowing the educational intervention. Education sessions incloude an educational video programme and a question and answer parts. For analyzing our data was used c hi-square, paired t-test, Spearma n and Pearson's correlation coefficient. Directed family planning education to couples with comorbidities significantly altered their attitude and knowledge. Counseling led to more informed choice behavior about family planning methods,by prioritizing permanent methods of vasectomy versus tubal ligation, especially after the education intervention (P<0.005). Family planning education and counseling directed to couples with multiple comorbidit ies should be a priority in health centers as because the appropriate contraceptive choice will improve their health literacy and outcomes

The association between CHA2DS2-VASc score and erectile dysfunction: a cross-sectional study

ABSTRACT Purpose: This study aims to assess the association between CHA2DS2-VASc score and erectile dysfunction in patients who were admitted to cardiology outpatient clinics. Materials and methods: One hundred and two male patients who were admitted to the cardiology outpatient clinic were included to the study. Erectile dysfunction was evaluated in the urology outpatient clinic in the same hospital and scored using Turkish Version of The International Index of Erectile Function. CHA2DS2-VASc score was calculated for every patient using the current associated guidelines. Results: There was a negative correlation between The International Index of Erectile Function score and CHA2DS2-VASc score, age, hypertension, heart failure, diabetes mellitus, stroke respectively. Smoking and dislipidemia were not correlated with The International Index of Erectile Function score (p>0.05). Conclusion: CHA2DS2-VASc score can be used to detect Erectile dysfunction in patients who are admitted to the cardiology outpatient clinics.

Factores que inciden en la aceptabilidad de la vasectomía / Factors that influence the acceptability of vasectomy

La vasectomía es un procedimiento que genera mínimas complicaciones y ostenta una tasa de éxito del 99 %; además tiene menor costo que la esterilización femenina, por lo cual se debe tener en cuenta el rol que desempeña el hombre en el número de hijos que se proyecta tener. En esta revisión de tema se identificaron los factores que inciden en la aceptabilidad de la vasectomía. Se realizó la búsqueda de la literatura en las bases de datos de PubMed, ProQuest, BioMed Central, ScienceDirect y Clinical Key para el periodo 2008-2017. Se seleccionaron 39 artículos por haber cumplido los criterios de inclusión: (a) publicado entre el 2008 y el 2017, en inglés, español o portugués y b) reportar resultados afines al tema de interés con evidencia de calidad científica durante la aplicación de las listas de chequeo. La sistematización y análisis de la información permitió la construcción de tres categorías temáticas: Entorno cultural, Condiciones sociales y Educación e información. Sobre la temática se evidenció que los factores como las creencias, el entorno sociocultural y la educación e información que tienen los hombres y sus parejas sobre la vasectomía influyen en la decisión de realizarse o no este procedimiento. Un hallazgo novedoso fue que el sexo de la descendencia también incide en esta decisión. Se recomienda una educación masiva para aumentar el acceso y conocimiento de la vasectomía.

Vasectomy is a procedure that generates minimum complications and garners a success rate of 99 %; In addition, it is an inex-pensive procedure in comparison to female sterilization, consequently the role of men should be taken into account when considering family planning. In this review of the topic, the factors that currently affect the acceptability of vasectomy were identified. We searched PubMed, ProQuest, BioMed Central, ScienceDirect and Clinical Key databases for articles published between 2008-2017 in English, Spanish or Portuguese, and included articles that met the inclusion criteria and showed scien-tific quality during the application of checklists. A total of 39 articles were admitted into the topic review. The systematization and analysis of the information allowed the construction of three thematic categories: cultural-environment, social conditions, and education and information. In this review, it is evidenced that factors such as beliefs, socio-cultural environment, and education and information that men and their partners have about vasectomy influences the decision to undergo or avoid this procedure. The sex of the offspring was evidenced as a novel factor because the children's gender influenced the decision. Therefore, mass education to increase the access and knowledge about vasectomy is recommended

Vasectomías en Colombia: ¿cómo adaptar los servicios de salud a las necesidades de los hombres? / Vasectomy in Colombia: how to adapt healthcare services to the needs of men? / Vasectomias na Colômbia: ¿como customizar os serviços da saúde nas necessidades dos homens?

Resumen Objetivo: Caracterizar sociodemográficamente a los hombres que se practican vasectomías en Colombia, para generar evidencia que oriente la adaptación de los servicios de salud, con un enfoque de equidad de género, a las necesidades de los hombres. Metodología: Estudio descriptivo a partir de la "Encuesta Nacional de Demografía y Salud" de 2015, y del registro de los usuarios que accedieron al servicio de vasectomía en la Asociación Probienestar de la Familia Colombiana (Profamilia) durante los años 2015 y 2016. Las variables utilizadas fueron: edad, nivel de escolaridad, lugar de residencia, pertenencia étnica, estrato de residencia, estado civil, número de hijos nacidos vivos y variables relacionadas con roles de género. Resultados: El porcentaje de hombres que acceden a la vasectomía ha aumentado, aunque no con la intensidad esperada. En términos generales, el perfil del hombre que decide realizarse la vasectomía en Colombia es un joven entre 30 y 40 años, de los estratos 2 y 3, residente en zonas urbanas, al menos con un nivel educativo de básica secundaria, casado y con hijos, y contribuyente al sistema de salud. Se observó la persistencia de barreras de tipo social y cultural que afectan el uso de este método anticonceptivo. Conclusiones: Este estudio permitió una aproximación al perfil del hombre colombiano que se realiza la vasectomía. Recomendaciones: Ampliar la vasectomía como opción disponible y de fácil acceso para los hombres; eliminar estereotipos de género, y promover que hombres y mujeres compartan responsabilidades anticonceptivas; implementar modelos de atención en salud sexual y reproductiva más inclusivos y centrados también en las necesidades de los hombres.

Abstract Objective: To demographically characterize men who undergo vasectomies in Colombia, in order to generate evidence to guide the adaptation of health services with a focus on gender equity to the needs of men. Methodology: Descriptive study based on the Colombian Demography and Health survey (2015) and the registry of users who accessed the vasectomy service in Profamilia during 2015 and 2016. The variables used were age, level of education, place of residence, ethnicity, residence stratum, marital status, number of children born alive and variables related to gender roles. Results: The percentage of men who have access to vasectomy has increased, although not with the expected intensity. In general terms, the profile of the man who decides to have a vasectomy in Colombia is between 30 and 40 years old in strata 2 and 3, resident in urban areas, at least with a secondary education level, married and with children, and also a contributor to the health system. The persistence of social and cultural barriers that affect the widespread and sustained use of this contraceptive method were observed. Conclusions: This study allowed identify the profile of the Colombian man who undergoes vasectomy. Recommendations: To extend vasectomy as an option of easily available and accessible method for men; to eliminate gender stereotypes and promote shared contraceptive responsibilities for men and women; as well as the implementation of models of sexual and reproductive health care, which become more inclusive and also focused on the needs of men.

A persistência das barreiras sociais e culturais que afetam o uso desse método contraceptivo foi observada. Conclusões: Este estudo permitiu identificar o perfil do homem colombiano submetido a uma vasectomia. Recomendações: Expandir a vasectomia como uma opção disponível e de fácil acesso para homens; eliminar estereótipos de gênero e promover que homens e mulheres compartilhem responsabilidades contraceptivas; implementar modelos de atenção em saúde sexual e reprodutiva mais inclusivos e também focados nas necessidades dos homens.

No scalpel vasectomy: a cross-sectional study of knowledge, attitude and practice of gynaecologists

Background: In spite of no scalpel vasectomy (NSV) being cheaper and safer, female sterilisations account for the majority of sterilisations performed worldwide. Research has focussed more on the “demand” and less on the “provider” side. Gynaecologists can be front-runners for the cause of population control in India. Hence, authors decided to estimate the knowledge of gynaecologists, their attitude and prevalent practice of NSV.Methods: Cross-sectional study. Interviewer-administered questionnaire used for face-to-face data collection from gynecologists registered with the Pune Obstetric and Gynecological Society.Results: Out of 447 gynecologists, 158 (35.3%) were males and 289 (64.7%) females. Mean age was 46.3 years ± 12.1 years, (range 24-80 years). Only 14 (3.1%) were trained in performing NSV. Only a minority knew about type of anaesthesia used (1.8%) and number of accesses needed (48.1%) for NSV. Only 40.7% and 18.1% knew about time to resume sexual activity and number of ejaculations to be covered by additional contraceptives after NSV respectively. More than half [258 (57.7%)] were willing to undergo training in NSV. Among those unwilling for training, female and older gynecologists (≥40 years) significantly outnumbered male and younger gynecologists (76.5% Vs. 23.5%; p=0.000 and 78.8% Vs. 21.2% respectively; p=0.000). Majority (79.9%) referred a couple willing for NSV to surgeons or urologists or advised female sterilization (17%).Conclusions: Knowledge of gynecologists about NSV was inadequate. Minority were trained in performing NSV. Male and younger gynecologists were willing to undergo training in NSV. Most preferred practices were referring couples elsewhere or advising female sterilization.

Barriers for low acceptance of no scalpel vasectomy among slum dwellers of Lucknow City

Background: Uttar Pradesh is the most populated state of the country having population of 199.581 million and total fertility rate of 3.3 (annual health survey [AHS] 2012�13) with high fertile trajectory. Currently, female sterilization accounts for about 18.4% and male sterilization for 0.3% of all sterilizations in Uttar Pradesh (AHS 2012�13). A strategy to promote men's involvement in effective birth control is needed to reduce the population growth. Since no scalpel vasectomy (NSV) is an easy method but still not being utilized; hence, the purpose of this research is to ascertain various factors of nonutilization of NSV. Objectives: The objective of the study is (i) to determine the barriers among married males for adopting NSV as a method of family planning, (ii) to determine the awareness about NSV, (iii) to suggest measures to increase uptake of NSV by the people. Methods: A cross-sectional study was carried out. A two-staged multistage random sampling technique was used. Lucknow is divided into eight Nagar Nigam zones. In the first stage, two urban slums from each geographical zone were selected randomly. In the second stage, from each selected slum a sample of 24 eligible households was selected at random to achieve the desired sample size. Results: It was observed that among the study participants maximum 89.2% perceived Sociocultural barriers, while 0.6% of the participants perceived service delivery barriers. However, 14% of the participants also perceived procedure-related barriers as the most important cause for not accepting NSV. Conclusion: Measures should be taken to remove these barriers, and increase uptake of NSV.

Attitudes towards vasectomy and its acceptance as a method of contraception among clinical-year medical students in a Malaysian private medical college

INTRODUCTION@#This study explored attitudes towards vasectomy and its acceptance as a method of contraception among clinical-year medical students, and determined the association between their demographic characteristics, and attitudes and acceptance.@*METHODS@#A cross-sectional survey was conducted among clinical-year medical students from a Malaysian private medical college using a self-administered questionnaire.@*RESULTS@#There were 330 participants with a female preponderance and a mean age of 22.0 ± 1.1 years. The largest proportion of respondents were from Year 3. The vast majority were ethnically Malay (91.8%) and followed Islam (92.4%). Overall, 60.9% of participants had a positive attitude towards vasectomy and 76.0% showed good acceptance. Gender, academic year, ethnicity and religion variables were not associated with attitudes and acceptance (p > 0.05). A significantly higher proportion of male respondents thought that vasectomy was religiously forbidden and would give a bad impression. A significantly higher proportion of Year 5 students agreed to the statement 'I would recommend vasectomy to relatives, friends and people close to me' compared to Year 3 and 4 students.@*CONCLUSION@#Students' perception of vasectomy as a contraceptive method was encouraging. Our results suggest that their knowledge improved as medical training progressed, and attitudes evolved for the better irrespective of their traditional, cultural and religious beliefs - highlighting the importance of providing students with evidence-based learning about male sterilisation, which is more cost-effective and is associated with lower morbidity than female sterilisation. A qualitative study involving students from different ethnicities and religions would provide a better understanding of this subject.

Do i need to see a urologist for my vasectomy? A comparison of practice patterns between urologists and family medicine physicians / 亚洲男科学杂志(英文版)

Urologists perform the majority of vasectomies in the United States; however, family medicine physicians (FMPs) perform up to 35%. We hypothesized that differences exist in practice patterns and outcomes between urologists and FMPs. Patients who underwent a vasectomy from 2010 to 2016 were identified. Postvasectomy semen analysis (PVSA) practices were compared between urologists and FMPs, before and after release of the 2012 AUA vasectomy guidelines. From 2010 to 2016, FMPs performed 1435 (35.1%) of all vasectomies. PVSA follow-up rates were similar between the two groups (63.4% vs 64.8%, P = 0.18). Of the patients with follow-up, the median number of PVSAs obtained was 1 (range 1-6) in both groups (P = 0.22). Following the release of guidelines, fewer urologists obtained multiple PVSAs (69.8% vs 28.9% pre- and post-2012, P < 0.01). FMPs had a significant but lesser change in the use of multiple PVSAs (47.5% vs 38.4%, P < 0.01). Both groups made appropriate changes in the timing of the first PVSA, but FMPs continued to obtain PVSAs before 8 weeks (15.0% vs 6.5%, P < 0.01). FMPs had a higher rate of positive results in PVSAs obtained after 8 weeks, the earliest recommended by the AUA guidelines (4.1% vs 1.3%, P < 0.01). Significant differences in PVSA utilization between FMPs and urologists were identified and were impacted by the release of AUA guidelines in 2012. In summary, FMPs obtained multiple PVSAs more frequently and continued to obtain PVSAs prior to the 8-week recommendation, suggesting less penetration of AUA guidelines to nonurology specialties. Furthermore, FMPs had more positive results on PVSAs obtained within the recommended window.

La mayoría tenía hijos al momento de la vasectomía y se sintió muy satisfecho con los resultados. Conclusión: Consideramos la vasectomía un procedimiento seguro, efectivo y de baja morbilidad, pero que requiere seguir un protocolo(AU)

Objective: To describe the experience achieved after 6 years performing vasectomies in the Minor Ambulatory Surgery sector of the Hospital Público Materno Infantil de Salta. Materials and methods: Retrospective, descriptive and qualitative study. Vasectomy statistics were analyzed from July 2010 to April 2016 considering socioeconomic data. Results: 187 traditional vasectomies were performed. The average age of men who had vasectomy was 34.6. The condom was the most used contraceptive method before they had a vasectomy. The average age of onset of sexual intercourse was 16.4 years. Most had children at the time of vasectomy and felt very satisfied with the results. Conclusion: We consider vasectomy a safe, effective and of low morbidity procedure, though it requires to follow a protocol(AU)

Effect of ductus deferens lavage on the time to achieve azoospermia in patients undergoing vasectomy

OBJECTIVE: To evaluate the effect of normal saline lavage of the distal vas deferens ampulla in patients undergoing vasectomy on the time to achieve azoospermia. METHODS: A prospective randomized study of 60 men divided into two groups, group lavage (GL, n=30) in which distal vas deferens ampulla lavage was performed with 10 ml of normal saline during the vasectomy, and group without lavage (GWL, n=30) in which control patients received only a vasectomy. The patients provided sperm for semen analysis at the 5th, 10th, 15th, 20th and 25th ejaculations. RESULTS: Fifteen participants in GL and 16 in GWL, for a total of 31 patients, were excluded due to not completing the control spermiogram. The tests carried out at the five ejaculations showed immobile spermatozoa in 40 and 85.71%, 66.67 and 78.57%, 93.33 and 85.71%, 86.67 and 71.43%, and 93.33 and 85.71% of participants in GL and GWL, respectively. CONCLUSION: Vas deferens duct lavage with 10 ml of normal saline during vasectomy did not decrease the time required to achieve postoperative azoospermia.

Vasectomy has no obvious longterm influence on the levels of serum androgens in aging males / 中华男科学杂志

Objective@#To explore the longterm influence of vasectomy on the levels of serum androgens in aging males.@*METHODS@#Using stratified random sampling, we conducted a questionnaire survey and physical examinations among 437 adult males aged ≥40 years, 232 with and 205 without the history of vasectomy. In addition, we measured the levels of serum total testosterone (TT), sexhormone binding globulin (SHBG), calculated free testosterone (cFT), testosterone secreting index (TSI), free testosterone index (FTI), and luteinizing hormone (LH).@*RESULTS@#Compared with the nonvasectomy group, the vasectomy group showed significantly increased levels of serum TT (［16.01±5.41］ vs ［17.39±6.57］ nmol/L), SHBG (［58.91±36.89］ vs ［70.28±40.90］ nmol/L), and LH (［8.86±6.49］ vs ［10.85±11.73］ IU/L) (all P0.05), nor after adjustment for relevant factors in TT (β: 1.015, 95% CI: －0.180－2.210), SHBG (β: 5.118, 95% CI: －2.069－12.305), cFT (β: 0.003, 95% CI: －0.011－0.018), FTI (β: －0.012, 95% CI: －0.035－0.011), TSI (β: 0.138, 95% CI: －0.131－0.407), and LH (β: 1.011, 95% CI: －0.811－2.834) (all P>0.05).@*CONCLUSIONS@#Vasectomy has no obvious longterm influence on the levels of serum androgens in aging males.

Expression and function of HSP110 family in mouse testis after vasectomy / 亚洲男科学杂志(英文版)

HSP110 functions to protect cells, tissues, and organs from noxious conditions. Vasectomy induces apoptosis in the testis; however, little is known about the reason leading to this outcome. The aim of the present study was to evaluate the expression and function of HSP110 in mouse testis after vasectomy. Following bilateral vasectomy, we used fluorescent Terminal deoxynucleotidyl transferase dUTP nick end labeling (TUNEL) to detect apoptosis, Western blotting and immunohistochemistry to examine HSP110 expression and localization. Serum antisperm antibody (AsAb) and testosterone were measured by Enzyme-linked immunosorbent assay (ELISA) and radioimmunoassay, respectively. Expression of endoplasmic reticulum stress (ERS) sensors and downstream signaling components was measured by Reverse Transcription-Polymerase Chain Reaction (RT-PCR), and the phosphorylation of eIF2 and JNK was detected by Western blotting. Vasectomy induced morphologic changes, increased apoptosis in the testis, increased serum AsAb, and decreased testosterone levels. After vasectomy, ORP150 mRNA level was increased first and then decreased, Bcl-2 was decreased, and the expression of HSPA4l, GRP78, GADD153, PERK, ATF6, IRE-1, XBP-1s, Bax, Bak, and caspases and the phosphorylation of eIF2 and JNK were increased. We present that an ER stress-mediated pathway is activated and involved in apoptosis in the testis after vasectomy. HSPA4l and ORP150 may play important roles in maintaining the normal structure and function of testis.
