Abstract
OBJECTIVES To provide up-to-date complication rates for vasectomy in the UK using 15 years of data collected by the Association of Surgeons in Primary Care (ASPC). PATIENTS AND METHODS Data were collected between 2007 and March 2022. A patient questionnaire was completed on the day of surgery and at 4 months postoperatively. Rates of early and late failure, infection, hospital admission or re-admission, haematoma and post-vasectomy pain syndrome (PVPS) were recorded. There were no specific exclusion criteria. Complication rates were compared to those published by major urological organisations. Descriptive statistics were utilised, without formal statistical analysis. RESULTS Over the 15-year study period, data from 105 393 vasectomies were collected, performed by >150 surgeons. In 2022, 94.4% of surgeons used one test to prove sterility. In all, 65% of patients used a postal sperm test after vasectomy to confirm sterility. Early failure rates were available for 69 500 patients. Early failure occurred in 648 patients (0.93%). Of 99 124 patients, late failure occurred in 41 (0.04%). Of 102 549 vasectomies, postoperative infection was reported in 1250 patients (1.22%), haematoma in 1599 patients (1.56%), and PVPS was reported in 139 patients (0.14%). CONCLUSIONS Vasectomy remains a safe and reliable contraceptive method. The rates of complication were generally lower than those published by major urological organisations. This large, prospective audit provides accurate, contemporaneous complication rates that can form the basis for pre-vasectomy counselling.

Abstract
OBJECTIVES Prior to the publication of the recommendations of the French Association of Urology (AFU) on vasectomy, we conducted a survey to assess current practices and required training interventions in France regarding vasectomy. METHOD An invitation with a link to a 38-item questionnaire on MonkeySurvey was sent in November 2022 to the 1760 urologist members of the AFU. RESULTS A total of 352 (20%) urologists completed the survey. Among the participants, 20% reported refusing the surgery to patients aged 25 to 30 years old and 17% if they had no children, respectively. Three quarters of participants mentioned systematically performing a scrotal exam at the time of the pre-vasectomy consultation. Forty-one percent of respondents reported systematically performing vasectomy under general anesthesia. While 56% of participants mentioned performing a minimally invasive technique for exposing the vas, 70% said they were willing to learn the no-scalpel technique for this purpose. The most frequently reported occlusion techniques combine excision of a vas segment and ligation of both ends of the divided vas. Only 26% reported performing fascial interposition and 4% using the "open end" technique. A post-vasectomy semen analysis showing less than 100,000 non-motile sperm per millilitre makes only 38% of respondents recommending stopping other contraceptive methods. Half of the respondents considered that current reimbursement fee structure for the procedure restrains the development of this clinical activity. CONCLUSION Our survey suggests that vasectomy practice and services in France do not meet the international standards. We identified the clinical and organizational changes needed to improve practices and access to vasectomy services in France. LEVEL OF EVIDENCE Grade 3.

Laparoscopic Salpingectomy and Vasectomy to Inhibit Fertility in Free-Ranging Nutrias (Myocastor coypus). Animals (Basel) 2023; 13:ani13061092. [PMID: 36978633 PMCID: PMC10044515 DOI: 10.3390/ani13061092] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/12/2023] [Revised: 03/16/2023] [Accepted: 03/17/2023] [Indexed: 03/22/2023] Open
Abstract
The nutria (Myocastor coypus), an invasive alien species, is widely spread in Europe. Pursuant to regulation (EU) no. 1143/2014, the nutria is subject to management programs to reduce its spread. Surgical fertility control is considered an acceptable method, particularly in urban circumstances, avoiding euthanasia. To maintain the hormonal patterns and the social and behavioral dynamics, surgical infertilization preserving the gonads (i.e., salpingectomy and vasectomy) is recommended. Mini-invasive surgery is an eligible choice when dealing with wildlife, allowing reduced captivation time. For these reasons, 77 free-ranging nutrias, captured in urban nuclei in Italy, underwent infertilization under general anesthesia; laparoscopic salpingectomy and vasectomy were performed on 32 animals and traditional surgery on the remainder, leaving the gonads in place. A three-port technique was used, with two paramedian trocars (5 mm) for the instruments and a median one for the telescope. Ablation was obtained through Onemytis® plasma device, allowing a rapid surgical time with no need to place visceral sutures; the skin was surgically closed. After recovery, the animals were released, and no overt complications were noted. No modification of the behavioral patterns was noted, and the population decreased during the following months.

Abstract
OBJECTIVES To answer the main clinical questions asked by practitioners and men consulting for a vasectomy request. METHOD The CPR method was used. The clinical questions were formulated according to the PICO methodology. A Pubmed literature search for the period 1984-2021 identified 508 references, of which 79 were selected and analyzed with the GRADE grid. RECOMMENDATIONS Vasectomy is a permanent, potentially reversible contraception. It is a safe procedure. A second vasectomy is necessary in only 1 % of cases. Surgical complications (hematoma, infection, pain, etc.) are rare. The frequency of prolonged scrotal pain after vasectomy is about 5 %, and less than 2 % describe a negative impact of this pain on their quality of life. Vasectomy does not have negative consequences on sexuality. The only contraindication to vasectomy is the minor patient. Patients at increased risk of remorse are single, divorced or separated men under the age of 30. Sperm storage may be particularly appropriate for them. Whatever the reason, the law allows the surgeon to refuse to perform the vasectomy. He must inform the patient of this at the first consultation. The choice of the type of anesthesia is left to the discretion of the surgeon and the patient. It must be decided during the preoperative consultation. Local anesthesia should be considered first. General anesthesia should be particularly considered in cases of anxiety or intense sensitivity of the patient to palpation of the vas deferens, difficulty palpating the vas deferens, or a history of scrotal surgery that would make the procedure more complex. Concerning the vasectomy technique, 2 points seem to improve the efficiency of the vasectomy: coagulation of the deferential mucosa and interposition of fascia. Leaving the proximal end of the vas deferens free seems to reduce the risk of post-vasectomy syndrome without increasing the risk of failure or complications. No-scalpel vasectomy is associated with a lower risk of postoperative complications than conventional vasectomy. Regarding follow-up, it is recommended to perform a spermogram at 3 months post-vasectomy and after 30 ejaculations. If there are still a few non-motile spermatozoa at 3 months, it is recommended that a check-up be performed at 6 months post-vasectomy. In case of motile spermatozoa or more than 100,000 immobile spermatozoa/mL at 6 months (defining failure), a new vasectomy should be considered. Contraception must be maintained until the effectiveness of the vasectomy is confirmed.

Comparison of postal and non-postal post-vasectomy semen sample submission strategies on compliance and failures: an 11-year analysis of the audit database of the Association of Surgeons in Primary Care of the UK. BMJ SEXUAL & REPRODUCTIVE HEALTH 2022; 48:54-59.

Abstract
BACKGROUND Vasectomy occlusive success is defined by the recommendation of 'clearance' to stop other contraception, and is elicited by post-vasectomy semen analysis (PVSA). We evaluated how the choice of either a postal or non-postal PVSA submission strategy was associated with compliance to PVSA and effectiveness of vasectomy. METHODS We studied vasectomies performed in the UK from 2008 to 2019, reported in annual audits by Association of Surgeons in Primary Care members. We calculated the difference between the two strategies for compliance with PVSA, and early and late vasectomy failure. We determined compliance by adding the numbers of men with early failure and those given clearance. We performed stratified analyses by the number of test guidance for clearance (one-test/two-test) and the study period (2008-2013/2014-2019). RESULTS Among 58 900 vasectomised men, 32 708 (56%) and 26 192 (44%) were advised submission by postal and non-postal strategies, respectively. Compliance with postal (79.5%) was significantly greater than with non-postal strategy (59.1%), the difference being 20.4% (95% CI 19.7% to 21.2%). In compliant patients, overall early failure detection was lower with postal (0.73%) than with non-postal (0.94%) strategy (-0.22%, 95% CI -0.41% to -0.04%), but this difference was neither clinically nor statistically significant with one-test guidance in 2014-2019. There was no difference in late failure rates. CONCLUSIONS Postal strategy significantly increased compliance to PVSA with similar failure detection rates. This resulted in more individuals receiving clearance or early failure because of the greater percentage of postal samples submitted. Postal strategy warrants inclusion in any future guidelines as a reliable and convenient option.

Risk of vasectomy failure by ligation and excision with fascial interposition: A prospective descriptive study. Contraception 2020; 101:342-349. [PMID: 32061567 DOI: 10.1016/j.contraception.2020.02.001] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/29/2019] [Revised: 01/26/2020] [Accepted: 02/05/2020] [Indexed: 10/25/2022]
Abstract
OBJECTIVE To evaluate the occlusive failure risk of ligation and excision with fascial interposition vasectomy technique. There are doubts about the effectiveness of this technique largely used in Asia and Latin America. STUDY DESIGN We conducted a prospective longitudinal observational descriptive study among men who underwent a vasectomy performed under local anesthesia in a clinic specializing in sexual and reproductive health services in Bogotá, Colombia. Three urologists used the Percutaneous No-Scalpel Vasectomy technique to isolate the vas deferens. They then ligated the vas, excised a 1 cm segment between ligations, and ligated the fascia on the prostatic end to cover the testicular end. We requested all patients to submit a semen sample three months after the vasectomy. We defined probable and confirmed vasectomy failure as 1-4.9 million sperm/ml and 5 million sperm/ml or more or any number of motile sperm observed on the last semen sample available, respectively. RESULTS Among 1149 participants, 581 (51%) had at least one post-vasectomy semen analysis. The overall failure risk was 5.2% (30/581; 95% confidence interval [CI] 3.6%-7.3%) with probable and confirmed failure risk of 1.9% (11/581; 95% CI 1.1%-3.4%) and 3.3% (19/581; 95% CI 2.1%-5.1%), respectively. Older men and one urologist had statistically significant higher risk of overall failure. CONCLUSION Our study confirmed that the ligation and excision with fascial interposition vasectomy technique is associated with an unacceptable risk of failure. IMPLICATIONS Surgeons who use the ligation and excision with fascial interposition vasectomy technique and countries with large vasectomy programs in Asia and Latin America that still recommend this technique should consider adopting alternatives to reduce the failure risk to below 1% as recommended by the American Urological Association.

Abstract
Vervet monkeys (Chlorocebus pygerythrus), considered a species of "least concern" by the International Union for Conservation of Nature (IUCN), are widely maintained at primate sanctuaries in South Africa. Permanent surgical contraception is a necessary method for the management of this species in captivity. In this study, a new vasectomy technique was evaluated and involves a prescrotal approach with only one surgical incision, aiming to excise a piece of vas deferens, leaving open the testicular side, and creating a loop on the prostatic side to avoid future recanalization. The birth rate was studied to assess the success of the technique. This technique significantly reduced breeding in the study population from 33 births in the first year to four births during the last year of the study. These results show that this type of vasectomy is a fast, simple, and safe technique for controlling monkey populations in sanctuaries.

Abstract
This report describes a technique for standing laparoscopic vasectomy in stallions through a prospective descriptive study. A preliminary study was carried out with two experimental intact male horses and subsequently the procedure was performed in two clinical cases. These horse owners want to keep their animals in the most possible natural way, preserving its stallion behaviour in a herd without generating offspring. The horses were sedated and restrained in stocks and laparoscopic vasectomy was performed using three portal sites in both paralumbar fossae recording surgical times. A 4-cm segment of each ductus deferens (DD) was occluded with laparoscopic vessel sealing devices and subsequently excised. Semen collection was performed using an artificial vagina before the laparoscopic procedure and at 15 and 60 days postoperatively. Sexual behaviour and spermiogram were analysed. Two months after vasectomy, control laparoscopy was performed in experimental horses to assess the surgical site. Bilateral vasectomy could be performed without intraoperative complications in a mean surgical time of 20 min per DD. Success of the procedure was confirmed in all cases by azoospermic ejaculates 60 days after vasectomy. This is the first time that the technique for laparoscopic vasectomy is described in horses.

Abstract
Background: Research evidence published 10 to 15 years ago has shown that the type of vasectomy surgical technique performed can influence the effectiveness and the safety of the procedure. The objective of this study was to determine if evidence-based vasectomy surgical techniques are integrated in the vasectomy programs of selected low-resource countries. Methods: The surgical techniques recommended to perform the two steps of the vasectomy procedure (isolation/exposition and occlusion of the vas deferens) were extracted from current evidence-based clinical practice guidelines. Documents describing male sterilisation standards and practice from Kenya, Rwanda, India, Nepal, Mexico, Honduras, Colombia and Haiti were reviewed to assess adequacy with international guideline recommendations. Results: Best recommended techniques are 1) a minimally invasive technique including the no-scalpel technique (known as the no-scalpel vasectomy (NSV)) to isolate and expose the vas deferens, and 2) cautery of the mucosa of the vas preferably combined with interposition of the fascia (FI) to occlude the vas deferens. The NSV is largely adopted and performed to isolate the vas in selected low-resources countries. Ligation and excision (LE) of a small segment of the vas deferens combined with FI is the most common vas occlusion technique mentioned in the country standards. Cautery as recommended in the guidelines is seldom used in selected countries. Conclusions: Effective and adapted vasectomy vas occlusion techniques are available, but are still underused in many low-resource countries. Providing the most effective vasectomy surgical techniques increases users' confidence and satisfaction regarding male sterilization and may lead to higher acceptability and uptake.

Abstract
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.

Abstract
In this study, ultrasound-assisted cloud point extraction (UA-CPE) method was developed for the determination of Ni(II) and Co(II) in milk-based products. After extraction and preconcentration, the Ni(II) and Co(II) contents of samples were determined by flame atomic absorption spectrometry (FAAS). After their complexation with hydroxy naphthol blue (HNB) in the presence of cationic surfactant, CTAB at pH 4.0, the Ni(II) and Co(II) were taken within the micellar phase of nonionic surfactant, TX-114. The micellar phase containing the analytes were diluted to a volume of 0.7 mL with 1.0-mol/L HNO3 in ethanol to reduce its viscosity and to facilitate sample treatment and then was analyzed by FAAS. The various analytical parameters affecting UA-CPE efficiency were investigated. The analytical features obtained after optimization are as follows: limits of detection are 0.56 and 0.78 μg/L; sensitivity enhancement factors are 48.6 and 53.9; the calibration curves were linear 3-180 and 2-160 μg/L for Co(II) and Ni(II), respectively, after preconcentration of 50-fold. The precision (as RSD%) between 1.8-3.6% and 2.2-3.8% (25 and 100 μg/L, n = 5) for Ni(II) and Co(II), respectively. The accuracy was statistically verified by analysis of two certified reference material samples (CRMs), including recovery studies after spiking. The method was applied to the analysis of milk-based samples with satisfied results.

Abstract
INTRODUCTION Post-vasectomy pain syndrome (PVPS) is a challenging problem for the practicing urologist because of its unclear pathophysiology and no clearly established protocol for evaluation or treatment. PVPS is defined as at least 3 months of chronic or intermittent scrotal content pain after a vasectomy procedure once other etiologies for the pain have been ruled out. AIM To systematically review the current literature on the effectiveness of micro-denervation of the spermatic cord (MDSC) for PVPS. METHODS A systematic literature search using PubMed, Scopus, Medline, Embase, and Cochrane databases for all reports pertaining to PVPS using the Medical Subject Heading terms post vasectomy pain syndrome and micro-denervation of spermatic cord through February 2017. MAIN OUTCOME MEASURES Scrotal content pain after MDSC for PVPS. RESULTS There were nine retrospective studies evaluating MDSC for chronic testicular pain. After omitting repeated series, there were 213 patients who underwent MDSC for chronic orchialgia. Only one study specifically reviewed the outcomes of patients who underwent MDSC for PVPS. In this study, 17 patients underwent MSDC for PVPS, with 13 (76.5%) reporting complete relief of pain at their first follow-up visit. The other four patients had significant improvement in pain and were satisfied with the results. Long-term follow-up data were not available for this study. CONCLUSION MDSC remains a valuable approach with high success rates and should be considered for PVPS that is refractory to medical therapy. MDSC appears to have the most success for patients who experience a temporary relief from a cord block and can significantly improve the patient's quality of life and ability to return to daily activities.

Abstract
Purpose: To determine the prevalence of unilateral absence of vas deferens (UAVD) in men with both testes seeking vasectomy. Materials and Methods: Computerized charts of 23,013 patients encountered between January 1994 and December 2013 in one university hospital and two community clinics of Quebec City, Canada, were searched. Pre-vasectomy consultation, operative reports and semen analysis results were reviewed to identify cases of UAVD. Cases were categorized as confirmed (unilateral vasectomy and success confirmed by semen analysis) or possible congenital UAVD further sub-categorized according to whether or not a scrotal anomaly was present. Results: Among 159 men identified as potentially having UAVD, chart review revealed that 47 had only one testicle, 26 had bilateral vasa, and four were misdiagnosed (post-vasectomy semen analysis [PVSA] showing motile sperm after unilateral vasectomy) leaving 82 men deemed cases of UAVD (0.36%, 95% confidence interval 0.28% to 0.43%). These were classified as confirmed (n=48, 0.21%) and possible (n=34, 0.15%; 22 without and 12 with scrotal anomalies) congenital UAVD. The misdiagnosis ratio of UAVD was low when scrotal content was otherwise normal (1:48), but higher if anomalies were present (3:12). Conclusions: Most surgeons who perform vasectomy will encounter cases of UAVD. In most suspected cases, it is safe and effective to proceed with unilateral vasectomy under local anesthesia while stressing the need for PVSA. Further studies or scrotal exploration may be considered in patient with prior scrotal surgery.

Abstract
Vasectomy is a highly effective and safe contraceptive method for couples who want to stop childbearing, but only 2.4% of men around the world use this method. We conducted an extensive review of the vasectomy research literature and programmatic reports, published between April 2005 and April 2015, to synthesize barriers and facilitators to vasectomy adoption. Of the more than 230 documents initially retrieved in our search, we ultimately included 75 documents in our review and synthesized the findings according to the Supply-Enabling Environment-Demand (SEED) Programming Model. Regarding promoting demand for vasectomy services, we found there was a general lack of awareness about the method among both men and women, which often fueled erroneous assumptions about how vasectomy affects men. Several types of programmatic activities directly addressed knowledge gaps and negative misperceptions, including community-based and mass media communications, employer-based promotion, and group counseling. For supply of services, the lack of or inaccurate knowledge about vasectomy was also prevalent among providers, particularly among community-based health workers. Programmatic activities to improve service delivery included the use of evidence-based vasectomy techniques such as no-scalpel vasectomy, whole-site trainings, task shifting, cascade training, and mobile outreach. Finally, programmatic approaches to building a more enabling environment included engagement of governments and other community and religious leaders as well as campaigns with gender transformative messaging that countered common myths and encouraged men's positive engagement in family planning and reproductive health. In summary, a successful vasectomy program is comprised of the mutually reinforcing components of continual demand for services and access to and supply of well-trained providers. In addition, there is an underlying need for enabling policies within the cultural and gender environments that extend beyond vasectomy and include men not just as default partners of female family planning clients but as equal beneficiaries of family planning and reproductive health programs in their own right. Accelerating progress toward meaningful integration of vasectomy into a comprehensive contraceptive method mix is only possible when political and financial will are aligned and support the logistical and promotional activities of a male reproductive health agenda.

Abstract
OBJECTIVES There is no trial comparing bipolar cautery and ligation for occlusion of vas in non-scalpel vasectomy. This study aimed to compare the effectiveness of these vasectomy occlusion techniques. MATERIALS AND METHODS Between January 2002-June 2009, patients were allocated in alternate order. We recruited 100 cases in cautery group and 100 cases in ligation group. Non-scalpel approach was performed during vasectomy and fascial interposition was performed in all cases. First semen analysis was done 3 months after vasectomy. Vasectomy success was defined as azoospermia or non-motile sperm lower than 100.000/mL. RESULTS Four patients from the cautery group were switched to the ligation group due to technical problem of cautery device. Thus, data of 96 patients as cautery group and 104 patients as ligation group were evaluated. After vasectomy, semen analyses were obtained from 59 of 96 (61.5%) patients in cautery group and to 66 of 104 (63.5%) patients in ligation group. There was no statistical significant difference between the two groups in terms of the success of vasectomy (p=0.863). CONCLUSION Although bipolar cautery technique is safe, effective and feasible in non-scalpel vasectomy, it has no superiority to ligation. There was no statistically significant difference in terms of the success and complications between the two groups.

Abstract
PURPOSE Teaching the no-scalpel vasectomy is important, since vasectomy is a safe, simple, and cost-effective method of contraception. This minimally invasive vasectomy technique involves delivering the vas through the skin with specialized tools. This technique is associated with fewer complications than the traditional incisional vasectomy (1). One of the most challenging steps is the delivery of the vas through a small puncture in the scrotal skin, and there is a need for a realistic and inexpensive scrotal model for beginning learners to practice this step. MATERIALS AND METHODS After careful observation using several scrotal models while teaching residents and senior trainees, we developed a simplified scrotal model that uses only three components-bicycle inner tube, latex tubing, and a Penrose drain. RESULTS This model is remarkably realistic and allows learners to practice a challenging step in the no-scalpel vasectomy. The low cost and simple construction of the model allows wide dissemination of training in this important technique. CONCLUSIONS We propose a simple, inexpensive model that will enable learners to master the hand movements involved in delivering the vas through the skin while mitigating the risks of learning on patients.

Abstract
BACKGROUND Currently, the two most common surgical techniques for approaching the vas during vasectomy are the incisional method and the no-scalpel technique. Whereas the conventional incisional technique involves the use of a scalpel to make one or two incisions, the no-scalpel technique uses a sharp-pointed, forceps-like instrument to puncture the skin. The no-scalpel technique aims to reduce adverse events, especially bleeding, bruising, hematoma, infection and pain and to shorten the operating time. OBJECTIVES The objective of this review was to compare the effectiveness, safety, and acceptability of the incisional versus no-scalpel approach to the vas. SEARCH METHODS In February 2014, we searched the computerized databases of CENTRAL, MEDLINE, POPLINE and LILACS. We looked for recent clinical trials in ClinicalTrials.gov and the International Clinical Trials Registry Platform. Previous searches also included in EMBASE. For the initial review, we searched the reference lists of relevant articles and book chapters. SELECTION CRITERIA Randomized controlled trials and controlled clinical trials were included in this review. No language restrictions were placed on the reporting of the trials. DATA COLLECTION AND ANALYSIS We assessed all titles and abstracts located in the literature searches and two authors independently extracted data from the articles identified for inclusion. Outcome measures included safety, acceptability, operating time, contraceptive efficacy, and discontinuation. We calculated Peto odds ratios (OR) with 95% confidence intervals (CI) for the dichotomous variables. MAIN RESULTS Two randomized controlled trials evaluated the no-scalpel technique and differed in their findings. The larger trial demonstrated less perioperative bleeding (OR 0.49; 95% CI 0.27 to 0.89) and pain during surgery (OR 0.75; 95% CI 0.61 to 0.93), scrotal pain (OR 0.63; 95% 0.50 to 0.80), and incisional infection (OR 0.21; 95% CI 0.06 to 0.78) during follow up than the standard incisional group. Both studies found less hematoma with the no-scalpel technique (OR 0.23; 95% CI 0.15 to 0.36). Operations using the no-scalpel approach were faster and had a quicker resumption of sexual activity. The smaller study did not find these differences; however, the study could have failed to detect differences due to a small sample size as well as a high loss to follow up. Neither trial found differences in vasectomy effectiveness between the two approaches to the vas. AUTHORS' CONCLUSIONS The no-scalpel approach to the vas resulted in less bleeding, hematoma, infection, and pain as well as a shorter operation time than the traditional incision technique. No difference in effectiveness was found between the two approaches.

Abstract
BACKGROUND Vasectomy is safe and highly effective; however, it remains an underused method of family planning (FP) in Africa. In view of this, three Rwandan physicians were trained in no-scalpel vasectomy with thermal cautery and fascial interposition on the prostatic end as vasectomy trainers in 2010, and this initiative has resulted in over 2900 vasectomy clients from February 2010 to December 2012. STUDY DESIGN This cross-sectional descriptive study describes vasectomy clients (n=316) and their wives (n=300) from 15 randomly selected hospitals in Rwanda. RESULTS The vasectomy clients were mainly over age 40, had young children (age <3) and were married and cohabiting. Limited financial resources, satisfaction with existing family size and avoiding side effects from hormonal methods (wives') were key motivators for vasectomy uptake. High rates of previous FP use and high degree of interspousal communication are known correlates of higher FP use. CONCLUSIONS Future and current Rwandan FP programs and other interested parties will benefit from understanding which couples elect vasectomy, their motivations for doing so and their service utilization experiences. Better integration of vasectomy counseling and postvasectomy procedures will benefit the program. IMPLICATIONS Until this project, vasectomy projects in sub-Saharan Africa were viewed as unrealistic. This study confirms factors influencing vasectomy uptake identified in earlier research, but does so within a robust sample of vasectomy users and their wives and provides a strong understanding of who likely vasectomy users are in this context. Promotion of vasectomy services should be considered as an essential element of a healthy contraceptive method mix.

Abstract
OBJECTIVE Data on short-term (within a week) morbidity of No-Scalpel Vasectomy (NSV) is lacking. We studied clients' perceptions of early post-vasectomy morbidity by self innovated postcard pictorial questionnaire. METHODS Between March 2011 and April 2012, 821 men underwent NSV and provided pre-printed revalidated pictorial postcards depicting various grades of severity of local pain, swelling, and bleeding. Clients were asked to tick mark their problems and post them on the third day after NSV. Data were compiled and statistically analyzed. RESULTS Completed postcards were returned by 702 clients (85.5%). 25 postcards were excluded due to illegitimate filling of card. About 80.8% of clients complained of pain and minimal, moderate and severe pain was experienced by 77.69%, 18.09% and 4.20%, respectively. 16.24% of clients observed local swelling, which was minimal in 90.9%, moderate and severe in 7.27% and 1.81% of cases. 2.95% of clients noted mild bloody discharge. Most of clients managed their problems by following the instructions given in postcards; level 1 and 2 morbidity did not affect their daily activity. CONCLUSION Early morbidity after NSV is usually mild in severity and easily manageable. The postcard system is a feasible, effective, and economical way of collecting data and managing short-term post NSV problems.

Abstract
PURPOSE The purpose of this guideline is to provide guidance to clinicians who offer vasectomy services. MATERIALS AND METHODS A systematic review of the literature using the search dates January 1949-August 2011 was conducted to identify peer-reviewed publications relevant to vasectomy. The search identified almost 2,000 titles and abstracts. Application of inclusion/exclusion criteria yielded an evidence base of 275 articles. Evidence-based practices for vasectomy were defined when evidence was available. When evidence was insufficient or absent, expert opinion-based practices were defined by Panel consensus. The Panel sought to define the minimum and necessary concepts for pre-vasectomy counseling; optimum methods for anesthesia, vas isolation, vas occlusion and post-vasectomy follow up; and rates of complications of vasectomy. This guideline was peer reviewed by 55 independent experts during the guideline development process. RESULTS Vas isolation should be performed using a minimally-invasive vasectomy technique such as the no-scalpel vasectomy technique. Vas occlusion should be performed by any one of four techniques that are associated with occlusive failure rates consistently below 1%. These are mucosal cautery of both ends of the divided vas without ligation or clips (1) with or (2) without fascial interposition; (3) open testicular end of the divided vas with MC of abdominal end with FI and without ligation or clips; and (4) non-divisional extended electrocautery. Patients may stop using other methods of contraception when one uncentrifuged fresh semen specimen shows azoospermia or ≤ 100,000 non-motile sperm/mL. CONCLUSIONS Vasectomy should be considered for permanent contraception much more frequently than is the current practice in the U.S. and many other nations.

Abstract
BACKGROUND Recent developments in vasectomy research indicate that occluding the vas using cautery combined with fascial interposition (FI) significantly lowers failure rates and is an appropriate technology for low-resource settings. We report the introduction of this technique in Ministry of Health (MOH) vasectomy services in Rwanda. DESIGN In February 2010, an international vasectomy expert trained three Rwandan physicians to become trainers in no-scalpel vasectomy (NSV) with thermal cautery and FI. The training took place over 5 days in five rural health centers. RESULTS A total of 67 men received vasectomies (11-16 per day) and trainees successfully mastered the new occlusion technique. The MOH is now scaling up NSV with cautery and FI services nationwide. The initial cadre of trainers has subsequently trained 46 other physicians in this vasectomy technique across 27 districts of Rwanda. CONCLUSIONS No-scalpel vasectomy with thermal cautery and FI was successfully introduced in vasectomy services in Rwanda, and a similar initiative should be evaluated in other national vasectomy services worldwide.

Abstract
CONTEXT The European Association of Urology presents its guidelines for vasectomy. Vasectomy is highly effective, but problems can arise that are related to insufficient preoperative patient information, the surgical procedure, and postoperative follow-up. OBJECTIVE These guidelines aim to provide information and recommendations for physicians who perform vasectomies and to promote the provision of adequate information to the patient before the operation to prevent unrealistic expectations and legal procedures. EVIDENCE ACQUISITION An extensive review of the literature was carried out using Medline, Embase, and the Cochrane Database of Systematic Reviews from 1980 to 2010. The focus was on randomised controlled trials (RCTs) and meta-analyses of RCTs (level 1 evidence) and on well-designed studies without randomisation (level 2 and 3 evidence). A total of 113 unique records were identified for consideration. Non-English language publications were excluded as well as studies published as abstracts only or reports from meetings. EVIDENCE SYNTHESIS The guidelines discuss indications and contraindications for vasectomy, preoperative patient information and counselling, surgical techniques, postoperative care and subsequent semen analysis, and complications and late consequences. CONCLUSIONS Vasectomy is intended to be a permanent form of contraception. There are no absolute contraindications for vasectomy. Relative contraindications may be the absence of children, age <30 yr, severe illness, no current relationship, and scrotal pain. Preoperative counselling should include alternative methods of contraception, complication and failure rates, and the need for postoperative semen analysis. Informed consent should be obtained before the operation. Although the use of mucosal cautery and fascial interposition have been shown to reduce early failure compared to simple ligation and excision of a small vas segment, no robust data show that a particular vasectomy technique is superior in terms of prevention of late recanalisation and spontaneous pregnancy after vasectomy. After semen analysis, clearance can be given in case of documented azoospermia and in case of rare nonmotile spermatozoa in the ejaculate at least 3 mo after the procedure.

Abstract
OBJECTIVE To examine the socio-demographic and reproductive characteristics of vasectomy acceptors and surgical features of vasectomy in Ghana. METHODS Retrospective review of 271 vasectomies performed between 1 January 2000 and 31 December 2009 in three healthcare facilities. RESULTS Less than 0.5% of family planning clients opt for vasectomy in Ghana; acceptors are both professional and semi-skilled workers. The mean age of vasectomy acceptors was 40.7 years, and their mean number of children four. All clients had two children or more; there was a trend towards a greater number of children with increasing age (p trend <0.001) or a lower educational level of the clients (p trend =0.01). Most clients obtained their information on vasectomy through the media and healthcare workers. Nearly all vasectomies were performed under local anaesthesia using the no-scalpel technique. The operating time of gynaecologists was significantly shorter than that of urologists (median operating time 10 minutes vs. 25 minutes; p <0.001). The reported vasectomy failure rate was about 1%. CONCLUSIONS The prevalence of vasectomy is low in Ghana. The factors influencing utilisation of male sterilisation services must be identified in order to improve uptake of this method of contraception in the country.

Abstract
The objective of the study was to standardize a new method of vasectomy in male rhesus macaques (Macaca mulatta). A total of 208 free range male rhesus macaques captured from different locations in Shivalik Hills in a population control programme of the rhesus macaques in India. General anaesthesia was achieved by using a combination of ketamine hydrochloride at 8 mg/kg body weight and xylazine hydrochloride at 2mg/kg body weight intramuscularly in squeeze cage. Surgical procedure of vasectomy was carried out by single-hole no-scalpel technique using a single pre-scrotal skin incision above the median raphae. Spermatic cord was grasped with ringed forceps and was pulled out through the single-hole incision. Vas deferens was separated from the artery-vein complexus and about 3-4 cm portion of vas deferens was resected. Cauterization of both ends of the vas deferens was achieved with electrocautery. The induction time for anaesthesia was 1.40±0.18 min while surgical time for vasectomy was found to be 5.09±0.22 min. Recovery from general anaesthesia was without side-effects after a mean duration of 36.07±1.22 min, whereas the duration of anaesthesia was observed to be 82.27±4.96 min. There were no major complications following the surgery and recovery of animals was smooth. Animals were kept in postoperative care for five days and released at the same capturing site.

Abstract
INTRODUCTION Recent research on vasectomy shows that combining cautery and fascial interposition (FI) achieves the most effective occlusion of the vas and minimizes the risk of failure. We present a technique that combines cautery and FI and is suitable for low-resource settings. SURGICAL TECHNIQUE The surgical technique consists of 1) exposing the vas with the no-scalpel approach; 2) cauterizing the epithelium of lumen of the vas using a portable battery-powered cautery device; 3) performing FI by grasping internal spermatic fascia and applying a free tie with suture material on the fascia to cover the prostatic stump of the vas and separate the two ends of the cut vas; and 4) excising a small 0.5 to 1 cm of the testicular stump. COMMENTS To maximize vasectomy effectiveness, vasectomy providers should consider learning thermal cautery and FI to occlude vas deferens.

Abstract
Male sterilization (vasectomy) is the most effective form and only long-acting form of contraception available to men in the United States. Compared to female sterilization, it is more efficacious, more cost-effective, and has lower rates of complications. Despite these advantages, in the United States, vasectomy is utilized at less than half the rate of female sterilization. In addition, vasectomy is least utilized among black and Latino populations, groups with the highest rates of female sterilization. This review provides an overview of vasectomy use and techniques, and explores reasons for the disparity in vasectomy utilization in the United States.

Abstract
OBJECTIVES To explore whether health care, socioeconomic, or personal characteristics account for disparities observed in the utilization of vasectomy. More than 500,000 vasectomies are performed annually in the United States. The safety and efficacy of vasectomy make it a good family planning option, yet the factors related to use of male surgical sterilization are not well understood. In this analysis, we examined differences in vasectomy rates according to factors such as race and socioeconomic status. METHODS We analyzed data from the male sample of the 2002 National Survey of Family Growth to examine the use of vasectomy among the sample of men aged 30-45 (n = 2161). Demographic, socioeconomic, and reproductive characteristics were analyzed to assess associations with vasectomy. RESULTS About 11.4% of men aged 30-45 years reported having a vasectomy, representing approximately 3.6 million American men. Although 14.1% of white men had a vasectomy, only 3.7% of black and 4.5% of Hispanic men reported undergoing vasectomy. On multivariate analysis, a significant difference in the odds of vasectomy by race/ethnicity remained, with black (odds ratio = 0.20, 0.09-0.45) and Hispanic men (odds ratio = 0.41, 0.18-0.95) having a significantly lower rate of vasectomy independent of demographic, partner, and socioeconomic factors. Having ever been married, fathering 2 or more children, older age, and higher income were the factors associated with vasectomy. CONCLUSIONS After accounting for reproductive history, partner, and demographic characteristics, black and Hispanic men were less likely to rely on vasectomy for contraception. Further research is needed to identify the reasons for these race/ethnic differences and to identify factors that impede minority men's reliance on this means of fertility control.

Abstract
The effectiveness of various vasectomy techniques is reviewed, with a focus on methods used for vas occlusion. Spontaneous recanalization of the vas is more common than generally recognized and is often transient. Simple ligation and excision has an unacceptably high risk for failure. Techniques that include cautery seem to have a lower risk for failure than techniques that do not include cautery. There is insufficient evidence to recommend a particular standardized cautery technique, but adding fascial interposition to cautery seems to be associated with the lowest risk for failure.

Abstract
PURPOSE We evaluated the long-term outcomes of patients who underwent epididymectomy for the treatment of chronic epididymal pain. MATERIALS AND METHODS All 72 patients who underwent epididymectomy at our institution between 1994 and 2007 were invited to participate in the study. Patients were mailed questionnaires covering various aspects of the treatment. Questions regarding pain were rated on a scale between 0 and 10 (0--no pain, 10--severe pain). Patients who did not return the questionnaires were followed up by telephone and the medical case notes of all respondents were reviewed. Statistical analysis was performed using the Wilcoxon signed-rank and Fisher's exact tests with p <0.05 considered statistically significant. RESULTS A total of 53 patients participated (74% response rate) and mean followup was 7.4 years. Of these patients 45 (84.9%) underwent epididymectomy for post-vasectomy pain and the remainder (8 of 53, 15.1%) had the procedure for various nonvasectomy reasons. There were significant improvements in pain score in the post-vasectomy (mean 7.3 preoperative to 2.4 postoperative, p <0.001) and nonvasectomy (mean 7 preoperative to 2.8 postoperative, p = 0.002) groups. Of the patients in the post-vasectomy group 93.3% (42 of 45) had less or no pain postoperatively compared to 75% (6 of 8) in the nonvasectomy group. The satisfaction rate with epididymectomy was also higher in the post-vasectomy (42 of 45, 93.3%) compared to the nonvasectomy (5 of 8, 62.5%) group (p = 0.038). CONCLUSIONS With high patient satisfaction and a favorable long-term outcome epididymectomy appears to be an effective treatment option particularly for post-vasectomy chronic epididymal pain.

Abstract
OBJECTIVES To assess the effect of adding lumen diathermy fulguration to our standard technique of vas ligation with polyglactin 910 (Vicryl(TM), Ethicon, Sommerville, NJ, USA) excision and fascial interposition, in an attempt to improve our sterilization rates. We previously reported the effect of changing suture material on vasectomy success rates; 3005 post-vasectomy semen analyses (PVSA) revealed a decrease in sterilization rates after surgery on changing from chromic catgut to polyglactin 910. PATIENTS AND METHODS We retrospectively reviewed PVSA undertaken for vasectomies performed by urological surgeons at the Mid-Yorkshire NHS Trust for 18 months from September 2005 to February 2007. RESULTS There were 592 vasectomies in all; the age distribution of patients between the groups treated with the standard and new method was similar. Overall, 166 patients (28%) failed to provide two semen samples as instructed, and so were excluded from further analyses. Sterility was achieved in 367 patients (86%); a further 28 (7%) have indeterminate analyses to date, with one of the last two PVSAs showing sperm, with the PVSA of 32 (7%) patients showing persisting sperm. For the eight surgeons reviewed the sterility rates were broadly similar. CONCLUSIONS The introduction of diathermy fulguration of the lumen has not improved vasectomy sterilization rates, with up to 14% having sperm on PVSA.

Abstract
BACKGROUND Currently, the two most common surgical techniques for approaching the vas during vasectomy are the incisional method and the no-scalpel technique. Whereas the conventional incisional technique involves the use of a scalpel to make one or two incisions, the no-scalpel technique uses a sharp-pointed, forceps-like instrument to puncture the skin. The no-scalpel technique aims to reduce adverse events, especially bleeding, bruising, hematoma, infection and pain and to shorten the operating time. OBJECTIVES The objective of this review was to compare the effectiveness, safety, and acceptability of the incisional versus no-scalpel approach to the vas. SEARCH STRATEGY We searched the computerized databases of CENTRAL, MEDLINE, EMBASE, POPLINE and LILACS in May 2006. In addition, we searched the reference lists of relevant articles and book chapters. SELECTION CRITERIA Randomized controlled trials and controlled clinical trials were included in this review. No language restrictions were placed on the reporting of the trials. DATA COLLECTION AND ANALYSIS We assessed all titles and abstracts located in the literature searches and two authors independently extracted data from the articles identified for inclusion. Outcome measures included safety, acceptability, operating time, contraceptive efficacy, and discontinuation. MAIN RESULTS Two randomized controlled trials evaluated the no-scalpel technique and differed in their findings. The larger trial demonstrated less perioperative bleeding (Odds ratio (OR) 0.49; 95% Confidence Interval (CI) 0.27 to 0.89) and pain during surgery (OR 0.75; 95% CI 0.61 to 0.93), scrotal pain (OR 0.63; 95% 0.50 to 0.80), and incisional infection (OR 0.21; 95% CI 0.06 to 0.78) during follow up than the standard incisional group. Both studies found less hematoma with the no-scalpel technique (OR 0.23; 95% CI 0.15 to 0.36). Operations using the no-scalpel approach were faster and had a quicker resumption of sexual activity. The smaller study did not find these differences; however, the study could have failed to detect differences due to a small sample size as well as a high loss to follow up. Neither trial found differences in vasectomy effectiveness between the two approaches to the vas. AUTHORS' CONCLUSIONS The no-scalpel approach to the vas resulted in less bleeding, hematoma, infection, and pain as well as a shorter operation time than the traditional incision technique. No difference in effectiveness was found between the two approaches.
