Context: In the United States (US) men who undergo vasectomy and/or vasectomy reversal (vasovasotomy) are likely to pay out‐of‐pocket for these procedures. We characterized the publicly disclosed pricing of both procedures with a focus on variability in self‐pay prices. Methods: We queried all US hospitals for publicly disclosed prices of vasectomy and vasovasotomy. We assessed interhospital variability in self‐pay pricing and compared hospitals charging high (≥75th percentile) and low (≤25th percentile) self‐pay prices for either procedure. We also examined trends in pricing after the 2022 US Supreme Court decision that allowed individual states to ban abortion. Results: Of 6692 hospitals, 1375 (20.5%) and 281 (4.2%) disclosed self‐pay prices for vasectomy and vasovasotomy, respectively. There was a 17‐fold difference between the 10th and 90th percentile self‐pay prices for vasectomy ($421–$7147) and a 39‐fold difference for vasovasotomy ($446–$17,249). Compared with hospitals charging low (≤25th percentile) self‐pay prices for vasectomy or vasovasotomy, hospitals charging high (≥75th percentile) prices were larger (median 150 vs. 59 beds, p < 0.001) and more likely to be for‐profit (31.2% vs. 7.8%, p < 0.001), academic‐affiliated (52.7% vs. 23.1%, p < 0.001), and located in an urban zip code (70.1% vs. 41.3%, p < 0.001). From October 2022 to April 2023, the median self‐pay price of vasectomy increased by 10% (from $1667 to $1832) while the median self‐pay price of vasovasotomy decreased by 16% (from $3309 to $2786). Conclusion: We found large variability in self‐pay pricing for vasectomy and vasectomy reversal, which may serve as a barrier to the accessibility of male reproductive care. [ABSTRACT FROM AUTHOR]

INTRODUCTION: Despite being a commonly encountered urologic condition, there remains a paucity of understanding and literature on the management and natural history of isolated epididymal pain. Typically, patients who do not respond to conservative management undergo an epididymectomy; however, the literature on its efficacy is also scarce, with success rates varying from 10-90%. Our goal was to better describe the etiology and natural history of isolated epididymal pain and to describe the rates of success associated with epididymectomy. METHODS: A retrospective, case-control study was conducted at the Manitoba Men's Health Clinic, with the approval of the University of Manitoba Research Ethics Board. All patients presenting with chronic epididymitis, defined as discomfort or pain localized to the epididymis for at least three months, were identified. Information regarding patient demographics, past medical and surgical history, duration of pain, localization of pain, findings on previous ultrasounds, prior conservative therapies trialed, and response rates, as well as response rates to surgical therapy were collected. RESULTS: From April 2022 to April 2023, a total of 275 patients with chronic orchialgia were identified; among them, 74 patients presented with chronic isolated epididymal pain. On average, 22.9% of patients experienced symptoms for 3-6 months, 10% for 6-12 months, and 67.1% for over 12 months; 13.5% (n=10) had associated ejaculatory pain, 8.1% (n=6) had lower urinary tract symptoms, and 4.1% (n=3) had erectile dysfunction. Ultrasound findings were observed in 68.9% of patients, with 31.1% having an epididymal cyst, 27.1% having a varicocele, 5.4% having a spermatocele, and 4.1% having a hydrocele. Among those who underwent conservative therapy, only 36.2% of patients reported a positive response. Surgical intervention was performed on 23 patients, including 16 who underwent epididymectomy, three who underwent cord denervation, and two who underwent vasovasostomy and spermatocelectomy each. Most (81.3%, n=13) patients who underwent epididymectomy had a positive response to the surgical intervention, defined as no pain on followup, while all patients undergoing other surgical interventions experienced a positive response. CONCLUSIONS: Chronic epididymal pain is a condition with limited data surrounding its management. Prior to referral, a large proportion of patients did not undergo any conservative treatment, and of those that did, there was limited response. For those who underwent surgical intervention, all were pain-free on followup, except three patients who underwent epididymectomy. [ABSTRACT FROM AUTHOR]

Background and objectives: Vasovasostomy is a cost‐effective procedure for the reversal of vasectomy. A water‐tight adequately blood‐supplied mucosal anastomosis is required for better outcomes. This review aimed to compare the outcome of vasovasostomy performed by three different techniques: macroscopic, pure microsurgical, and robot‐assisted microsurgical techniques. Methods: Scopus, Web of Science, PubMed, Embase, and Cochrane library databases were searched for relevant studies from January 1901 to June 2023. We conducted our quantitative syntheses using the inverse variance method in OpenMeta software. The study's protocol was registered on PROSPERO. Results: This review involved 95 studies of different designs, with a total sample size of 48,132. The majority of operations were performed bilaterally, and participants were monitored for up to 10 years. The pooled patency rate was the highest following robot‐assisted vasovasostomy (94.4%), followed by pure microsurgical vasovasostomy (87.5%), and macroscopic vasovasostomy (83.7%). The pooled pregnancy rate following purely microsurgical vasovasostomy was higher than that of macroscopic vasovasostomy (47.4 vs. 43.7%). Definitive pregnancy rates in robotic vasovasostomy are yet to be determined. Conclusion: Patency outcomes for vasovasostomy were best with robot‐assisted microsurgical technique, followed by pure microsurgical technique, and conventional macroscopic technique. Further investigations of robot‐assisted microsurgical vasovasostomy outcomes and randomized control trials are required to support this evidence. [ABSTRACT FROM AUTHOR]

ABSTRACT Objective: This retrospective study aimed to evaluate the effectiveness of low-dose prednisone as a rescue therapy for patients with deteriorating semen parameters following vasovasostomy. Materials and Methods: Electronic medical records were queried at the University of Miami with documented CPT code 55400 (Bilateral Vasovasostomy) between January 2016 and April 2023. Records were then reviewed to identify patients who demonstrated ≥50% decrease in semen parameters, specifically sperm concentration, motility and total motile sperm count. Patients who were treated with 6 weeks of low-dose prednisone were identified, and baseline semen parameters and subsequent changes after prednisone therapy were assessed. A Mann-Whitney U Test was used to compare semen parameter changes before and after prednisone. Adverse effects associated with prednisone were monitored. Results: A total of 8 patients were identified with deteriorating semen parameters who were treated with 6 weeks of low-dose prednisone. Following prednisone therapy, all patients demonstrated improvements in total motile sperm count (TMSC), with a median improvement of 6 million. The median relative improvement in TMSC was 433%. Sperm concentration and motility also improved compared to post-operative baseline. No adverse effects were reported during the treatment period. Conclusions: Low-dose prednisone therapy appears to be a safe and effective intervention for managing deteriorating semen parameters following VV. The observed improvements in TMSC suggest the potential of prednisone to rescue patients with delayed failure after VV. Further research with larger sample sizes is warranted to confirm the safety and efficacy of low-dose prednisone as a rescue therapy in this specific patient population. Optimizing VV outcomes is crucial in male infertility, and further exploration of steroid therapy and innovative biotechnologies is warranted.

Purpose: Vasovasostomy is used to correct vas deferens (VD) transections encountered during surgery or to reverse sterilization vasectomies. Achieving vasal patency is the primary goal and the success is assessed on various factors including VD patency, flow rates, and pregnancy rates. While preserving vas motility is not a major concern in surgical practice, it is worth noting that VD has peristaltic activity which plays crucial role during ejaculation. Any disruption in its motility could potentially lead to negative outcomes in the future. We conducted an experimental study to assess vas motility changes following vasovasostomy. Methods: The study was approved by Gazi University, Animals Ethic Committee. Twenty-four rats were allocated to four groups. Left-sided VD was harvested in control group (Gr1). The rest of the animals were subjected to transection of VD. Gr2 and 3 underwent microscopic and macroscopic anastomosis, respectively, while Gr4 underwent vasal approximation. After 12 weeks, all left-sided VD were resected, electrical field stimulation (EFS) and exogenous drugs were applied to induce contractions. Statistical analyses were performed and p value < 0.05 was regarded as statistically significant. Results: The first and second phases of EFS-induced contractile responses(CR) increased for Gr3 and decreased for Gr4 at submaximal and maximal frequencies. An increase only at maximal frequency for second phase EFS-induced CR was encountered for Gr2. α-β-methylene-ATP-induced CR decreased for Gr3 and 4. Noradrenaline-induced CR increased for Gr2, and 3 and decreased for Gr4. Conclusion: The results suggest that vasovasostomy performed using a surgical technique that minimizes disruption or damage to VD may have a favorable impact on motility. [ABSTRACT FROM AUTHOR]

Family planning falls within the spectrum of care within our medical society. We sought to illustrate changes in contraceptive methods over time and evaluate tubal ligation and vasectomy reversal practices in Australia. Yearly data from 2000 to 2021 was extracted from 3 databases: Pharmaceutical Benefits Schedule, Medicare Benefit schedule and Australian Institute of Health and Welfare databases. Population adjusted rates of procedures and medical therapies were calculated using data from Australian Bureau of statistics. Use of Long acting reversible contraception (LARC) has increased by 34.1% from 2001 to 2021, with Mirena being the preferred contraception. The peak age group for tubal ligation during caesarean section was those >35-year-old (64.7%) whereas vasectomy more commonly performed in men aged 35–44. There was a 21.6% decrease in the number of vasectomies over time from 2000–2020. Female surgical sterilisation:vasectomy ratio shows tubal ligation was twice more common than vasectomy. Both macro/microsurgical anastomosis of the vas deferences were conducted: vasovasostomy (VV) and vasoepididymostomy (VE). There was a preponderance in the use of microsurgical approach for VV. Reversal mostly common occurred in those aged 40–44 at 29%. Overall, the rate of vasectomy is continuously falling over time whilst there is a steady incline in the use of LARC from 2020–2021. Both vasovasostomy and vasoepididymostomy reconstruction are practised. Although definitive conclusion from the literature lags, “real-world” trend indicate that micro-surgically conducted vasovasostomy might be the better surgical technique for desired patient outcomes.

Background: Men with idiopathic obstructive azoospermia (OA) are candidates for surgical reconstruction with a vasoepididymal anastomosis (VEA) performed on one or both testis. There are no randomised trials comparing the success of unilateral versus bilateral VEA. Objective: We conducted a randomised trial to compare the two surgical options. Design, setting, and participants: Between April 2017 and March 2022, men with infertility due to idiopathic OA were randomised to a unilateral (group 1) or bilateral (group 2) VEA in an ethics committee–approved clinical trial, registered with the Clinical Trials Registry. Outcome measurements and statistical analysis: The primary outcome was successful surgery, defined as appearance of sperm in the ejaculate, evaluated at 3 mo intervals after surgery. Additional outcomes were pregnancy rates and complications between the two groups. Men with successful surgery were compared with those without patency to identify the predictors of success. Results and limitations: Fifty-four men fulfilled the criteria and 52 who completed follow-up were included in the analysis. The overall patency rate was 36.5% (19/52 individuals). This was higher in men with bilateral surgery (12/26 patients, 46%) than in those with unilateral surgery (7/26 patients, 27%) but was not statistically significant (p = 0.1). The overall pregnancy rate with ejaculated sperm was significantly higher in the bilateral surgery group (4 vs 0, p = 0.037), while the spontaneous conception rate was higher but not statistically significant (3 vs 0, p = 0.074). The complication rates in the two groups were similar (p = 0.7), and all complications were Clavien-Dindo grade 1. Although bilateral surgery and presence of sperm in epididymal fluid were higher in men with patency, these were not statistically significant. Conclusions: A bilateral VEA was associated with higher patency and spontaneous pregnancy rates than unilateral surgery, but the results were not statistically significant. However, the overall pregnancy rate with ejaculated sperm, spontaneous and assisted, was significantly higher in the bilateral surgery group. Patient summary: In this study, we compared between unilateral and bilateral reconstructive surgery in azoospermic men and found better overall success with bilateral surgery. However, these results were not statistically significant.

Background: Good knowledge of contraceptives is a key component for contraceptive utilization by young women. There have been increased incidences of unwanted pregnancies and induced abortions in tertiary institutions. This study sought to assess the knowledge and pattern of utilization of contraceptives among female students in Eldoret National Polytechnic, Kenya (ENP). Objective: One of the specific objectives of the study was to assess Contraceptive literacy among female students of ENP in Kenya. Methods: The study design was a cross-sectional one in form of self-administered closed ended and open-ended questionnaires. Study population was only female students of ENP, aged between 18 and 35 years. Stratified random sampling was applied to the selected sample of 360 from the study population of 5879. Results: Majority of the respondents affirmed the knowledge on contraceptive method for pills (88.0%) injections (83.4%) male condoms (82.2%), and e-pills (88.0 %) while affirming the use of alternate methods such as withdrawal (62.3%) and abstinence (77.3%). Regarding the sources of the family (FP) services, most respondents scored highly on the sources of the contraceptives with injectables, male condoms, E-pill and oral contraceptive pills at 82.8%, 80.7%, 80.4% and 73.6% respectively. Conclusion: Most participants reported good knowledge and source for short term family planning (FP) methods while long term reversible contraceptive methods are least understood. Majority of students get contraceptive information from social media and peers. [ABSTRACT FROM AUTHOR]

Purpose of review: Vasectomy is a commonly performed outpatient procedure for male contraception with high success and low failure rates. Vasectomy reversal permits couples desiring the ability to conceive naturally after vasectomy to avoid assisted reproductive technology in many cases. Our review discusses current and emerging vasectomy and vasectomy reversal practices, techniques, and outcomes. Recent Findings: Various vasectomy techniques have been utilized for vas isolation and occlusion, most notably the no-scalpel vasectomy with intraluminal cauterization and fascial interposition. There are few comparative studies between vasectomy techniques, making it difficult to determine the optimal operative approach. Overall compliance rates with post-vasectomy semen analyses are low, complicating study of vasectomy success rates. The most common methods for reversal include vasovasostomy and vasoepididymostomy, each with their own range of techniques. With recent technological advancements, many novel approaches and tools have been employed to improve patency and pregnancy success such as robotic techniques and anti-fibrotic agents. In addition, there are many patient and partner factors that can affect vasectomy and vasectomy reversal outcomes. Vasectomy reversals need to be approached algorithmically with outcomes assessed based on technique and time since vasectomy. Summary: Further research across multiple institutions is needed comparing outcomes of novel vasectomy and vasectomy reversal to traditional approaches. Emerging non-surgical options for male contraception will play an important role in the practice of urologists in future years. [ABSTRACT FROM AUTHOR]

Although a wide array of interventions exist for men seeking fertility after vasectomy, up to 6% of them will elect for a vasectomy reversal. While the widespread adoption of telemedicine promises convenience and improved access, lack of ability to do a physical examination may hinder appropriate counselling. Although vasectomy reversal is successfully completed in most of the men either with a vasovasostomy or a vasoepididymostomy, there could be various reasons for the inability to successfully complete the operation. Our commentary outlines the reasons why a vasectomy reversal is not possible or successful. We also discuss a pre-operative management algorithm in men seeking vasectomy reversal to ensure appropriate counselling with a thorough pre-operative history, physical examination and on occasion, hormonal evaluation.

ABSTRACT Purpose: To evaluate the viability of the porcine vas deferens as a realistic microsurgical training model for vasectomy reversal Methods: The model uses swine testicles (vas deferent), which are usually discarded in large street markets since they are not part of Brazilian cuisine. The spermatic cord was carefully dissected, and the vas deferens were isolated, measuring 10 cm in length. A paper quadrilateral with 5 cm2 was built to delimit the surgical training field. The objective of the model is to simulate only the microsurgical step when the vas deferens are already isolated. The parameters analyzed were: feasibility for reproducing the technique, patency before and after performing the vasovasostomy, cost of the model, ease of acquisition, ease of handling, execution time, and model reproducibility. Results: The simulator presented low cost. All models made were viable with a texture similar to human, with positive patency obtained in 100% of the procedures. The internal and external diameters of the vas deferens varied between 0.2-0.4 mm and 2-3 mm, respectively, with a mean length of 9 ± 1.2 cm. The total procedure time was 43.28 ± 3.22 minutes. Conclusions: The realistic model presented proved to be viable for carrying out vasectomy reversal training, due to its low cost, easy acquisition, and easy handling, and providing similar tissue characteristics to humans.

Robot-assisted surgery is the gold standard of treatment in many fields of urology. In this systematic review, we aim to report its usage in andrology and to evaluate any advantages. A systematic search of the PubMed and Cochrane Library databases was conducted to identify articles referring to robotic-assisted microsurgery in andrology. The search strategy was in line with the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines and the Cochrane Handbook. The articles were then reviewed by two authors. A qualitative analysis of the articles that met the inclusion criteria was performed. Thirty-one articles that met the inclusion criteria were reviewed. The first results for robot-assisted vasovasostomy (RAVV) are encouraging as excellent patency rates, short operative times, and learning curves were achieved. Interestingly, patency rates were greater in some case series for RAVV than for microsurgical vasovasostomy, with a statistically significant difference. In addition, robot has been shown to be of great use in bypassing fibrotic changes in cases of iatrogenic vasal injuries, difficulties encountered with traditional microsurgery. In addition, the feasibility of robot-assisted microsurgery has been proven for varicocelectomy and microsurgical denervation of the spermatic cord, with acceptable improvement in sperm parameters and pain, respectively. The current evidence suggests that there are potential advantages of the use of robots in andrology. However, for robotic surgery to become incorporated into the daily use of the andrologists, large, multicenter randomized trials are needed. As robotics systems are becoming standard in urology practice, it is reasonable for one to believe that they will also find their place in andrology. [ABSTRACT FROM AUTHOR]

Objective: Vasovasostomy is the most common surgery to restore the fertility of vasectomized men. This study aimed to compare the outcomes of one-layer macroscopic VV (MOLVV) or two-layer microscopic VV (TLMVV) Methods: This study was performed on the medical records of 100 patients who underwent VV surgery in two tertiary hospitals from 2014 to 2017. All patient information, including demographic and sperm analysis, was collected. The chi-square test, independent t -test, and survival analysis using Kaplan–Meyer test and Cox regression were performed to analyze the data using SPSS software version 25, and the significance level was considered 0.05. Results: The fertility rate in patients of both groups was 15%. The findings showed a statistically significant difference between the mean percentage of normal sperm morphology according to the type of surgery (p = 0.045). There was no statistically significant difference between the mean sperm count, sperm motility percentage, and mean hospital costs according to the type of surgical procedure (p > 0.05). The incidence of spouse pregnancy in the TLMVV method after 15 and 24 months was 87.5% and 58.3%, respectively. In patients with unilateral anastomosis, the incidence of pregnancy at 13 and 15 months after surgery was 98.7% and 95.8%, respectively. The mean and median time of pregnancy in the spouses of patients with each surgical shower were 24 and 25 months. Other variables had no significant effect on spouse pregnancy. Conclusion: Vasovasostomy with the one and two-layer methods had equal results. The number, movement, and normal morphology of sperm after surgery were low. Therefore, these people will need assisted reproductive techniques. [ABSTRACT FROM AUTHOR]

Vasectomy damage is a common complication of open nonmesh hernia repair. This study was a retrospective analysis of the characteristics and possible causes of vas deferens injuries in patients exhibiting unilateral or bilateral vasal obstruction caused by open nonmesh inguinal herniorrhaphy. The site of the obstructed vas deferens was intraoperatively confirmed. Data, surgical methods, and patient outcomes were examined. The Anderson–Darling test was applied to test for Gaussian distribution of data. Fisher's exact test or Mann–Whitney U test and unpaired t-test were used for statistical analyses. The mean age at operation was 7.23 (standard deviation [s.d.]: 2.09) years and the mean obstructive interval was 17.72 (s.d.: 2.73) years. Crossed (n = 1) and inguinal (n = 42) vasovasostomies were performed. The overall patency rate was 85.3% (29/34). Among the 43 enrolled patients (mean age: 24.95 [s.d.: 2.20] years), 73 sides of their inguinal regions were explored. The disconnected end of the vas deferens was found in the internal ring on 54 sides (74.0%), was found in the inguinal canal on 16 sides (21.9%), and was found in the pelvic cavity on 3 sides (4.1%). Location of the vas deferens injury did not significantly differ according to age at the time of hernia surgery (≥12 years or

Vasectomy is performed as a permanent method of contraception for men after completing the family. Many men are seeking vasectomy reversal operations after remarrying new partners. The reversal operation is seen as a challenging procedure that requires a skilled surgeon and sophisticated instruments. This write‐up reports a case of vasovasostomy performed successfully on an elderly man using the minimal available facilities at Phuentsholing General Hospital, Bhutan. Vasectomy reversal operation is seen as challenging procedure in the resource constraint country, Bhutan. Men seeking reversal operation were denied of the services due to unavailability of the expertise to perform the procedure. However, this write‐up summerises the successful reversal operation performed on an elderly man. In Bhutan, gynecologist and the general surgeons should take up this field and start providing services to men seeking vasectomy reversal operation. [ABSTRACT FROM AUTHOR]

Background Vasectomy is a procedure that results in permanent yet reversible sterility and remains a great contraceptive option for many. Previous research studies have highlighted frequency of vasectomy utilization, defining characteristics of individuals who opt for this method, various surgical techniques, and the risks and benefits associated with the procedure. What remains to be defined is why or why not individuals may experience post-vasectomy regret and whether the previous characteristics correlate. Objective The objective of this review is to synthesize information regarding reasons individuals may regret their vasectomy and seek reversal, what options exist for accomplishing the reversal, and patients' fertility prognosis post-vasovasostomy. Methods This review utilized a combination of secondary and tertiary data analysis across a wide scope of academic databases pertaining to the topic of interest. Results Typically, most males who have sought a vasectomy are satisfied with their decision, however, approximately 6% of this population seeks reversal. Key factors influencing vasectomy regret include age at the time of vasectomy, parental status, pre- and post-operative relationship status, unresolved physical and psychosexual problems, and development of chronic scrotal pain following the procedure. Few options exist for vasectomy reversal including microsurgical reconstructive vasectomy reversal (VR) and sperm extraction for in vitro fertilization. There is no guarantee that fertility will be restored in any case but a major predictive factor for success is the time interval prior to reversal. Conclusion Vasectomy is intended to be a permanent form of contraception; however, a minor chance remains that individuals may experience post-operative regret due to various factors. This warrants proper comprehensive counseling by the patient's provider regarding benefits and risks, procedural outcomes, opportunities for reversal, and fertility prognosis. [ABSTRACT FROM AUTHOR]

The objective of this study was to identify factors that predict for sperm granuloma formation and the impact of sperm granuloma presence and quantity on vasectomy reversal (VR) outcomes. A cross sectional retrospective review of prospectively collected data, on the impact of granuloma on VR outcomes from a single academic center was performed. The impact of age, obstructive interval, intraoperative vasal fluid findings, anastomosis type, body mass index, tobacco use and total motile count (TMC) was determined. A total of 1550 men underwent VR between January 2000 and August 2019. Granulomas were present unilaterally in 23.3% (n = 361) and bilaterally in 14.2% (n = 220). On univariate analysis, increasing patient age negatively correlated with a larger number of granulomas (p =.011). Granuloma presence was associated with finding intact and motile sperm from the vasal stump intraoperatively (p =.001), and vasoepididymostomy anastomosis (p <.001). However, granuloma presence (and quantity) did not correlate with obstructive interval or maximum TMC. Tobacco use and body mass index (BMI) were not associated with granuloma presence. On multivariate analysis, granuloma quantity was not associated with TMC. Obstructive interval and vasovasostomy anastomosis were associated with higher TMC, while BMI was negatively associated with TMC. In conclusion, increasing age was negatively correlated with granuloma formation. Granuloma presence was associated with more favourable intraoperative fluid findings and anastomosis type, but not post‐VR TMC, suggesting men with and without granulomas undergoing skilled microsurgery will have similar patency rates. Heavier men should be encouraged for weight loss prior to vasectomy reversal as increasing BMI was associated with lower TMC. [ABSTRACT FROM AUTHOR]

Male infertility may occur due to obstructive and non-obstructive reasons, and some pathologies may be corrected with surgical and medical treatment. Such treatment may increase the possibility of spontaneous pregnancy, the success of assisted reproductive technology, and also testicular sperm retrieval rate. This review will focus on surgical treatment alternatives in infertile males. Although treatment options for varicocele in infertile men include open surgical, radiologic, and laparoscopic approaches; microsurgical varicocele repair has the highest improvement in postoperative sperm parameters with lower complication rates. Recent advances in microsurgical anastomosis techniques have increased the patency rate for proximal epididymal obstruction. Although treatment options for distal ejaculatory duct obstruction include endoscopic resection, balloon dilatation, and laser incision/excision, transurethral resection of the ejaculatory duct (TURED), is still the primary gold standard treatment of distal ejaculatory duct obstruction. The testicular sperm retrieval rate has increased with the management of correctable pathologies in men with non-obstructive azoospermia. In case of treatment failure of correctable or uncorrectable pathologies of male factor infertility, surgical sperm obtained from the urogenital tract may necessary for assisted reproductive technology. Surgical success rates for male infertility and the success of surgical sperm obtained procedures have increased dramatically over the last decades attributable to the development of microsurgical techniques and endoscopic equipment, instrumentation, and techniques.

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

Optimal vision and ergonomics are essential factors contributing to the achievement of good results during microsurgery. The three-dimensional (3D) digital image microscope system with a better 3D depth of field can release strain on the surgeon's neck and back, which can improve outcomes in microsurgery. We report a randomized prospective study of vasoepididymostomy and vasovasostomy using a 3D digital image microscope system (3D-DIM) in rats. A total of 16 adult male rats were randomly divided into two groups of 8 each: the standard operating microscope (SOM) group and the 3D-DIM group. The outcomes measured included the operative time, real-time postoperative mechanical patency, and anastomosis leakage. Furthermore, a user-friendly microscope score was designed to evaluate the ergonomic design and equipment characteristics of the microscope. There were no differences in operative time between the two groups. The real-time postoperative mechanical patency rates were 100.0% for both groups. The percentage of vasoepididymostomy anastomosis leakage was 16.7% in the SOM group and 25.0% in the 3D-DIM group; however, no vasovasostomy anastomosis leakage was found in either group. In terms of the ergonomic design, the 3D-DIM group obtained better scores based on the surgeon's feelings; in terms of the equipment characteristics, the 3D-DIM group had lower scores for clarity and higher scores for flexibility and adaptivity. Based on our randomized prospective study in a rat model, we believe that the 3D-DIM can improve surgeon comfort without compromising outcomes in male infertility reconstructive microsurgery, so the 3D-DIM might be widely used in the future.

We aimed to characterise diverse practice patterns for vasal reconstruction and to determine whether surgeon volume is associated with vasoepididymostomy performance at the time of reconstruction. We identified adult men who underwent vasal reconstruction from 2000 to 2020 in Premier Healthcare Database and determined patient, surgeon, cost and hospital characteristics for each procedure. We identified 3,494 men who underwent either vasovasostomy‐alone (N = 2,595, 74.3%) or any‐vasoepididymostomy (N = 899, 25.7%). The majority of providers (N = 487, 88.1%) performed only‐vasovasostomy, 10 (1.8%) providers performed only‐vasoepididymostomy and 56 (10.1%) providers performed both. Median total hospital charge of vasoepididymostomy was significantly higher than vasovasostomy ($39,163, interquartile range [IQR]$11,854–53,614 and $17,201, IQR$10,904–29,986, respectively). On multivariable regression, men who underwent procedures at nonacademic centres (OR 2.71, 95% CI 2.12–3.49) with higher volume surgeons (OR 11.60, 95% CI 8.65–16.00) were more likely to undergo vasoepididymostomy. Furthermore, men who underwent vasoepididymostomy were more likely to self‐pay (OR 2.35, 95% CI 1.83–3.04, p <.001) and more likely had procedures in the Midwest or West region (OR 2.22, 95% CI 1.66–2.96 and OR 2.11, 95% CI 1.61–2.76, respectively; p <.001). High‐volume providers have increased odds of performing vasoepididymostomy at the time of reconstruction but at a significantly higher cost. These data suggest possibly centralising reconstructive procedures among high‐volume providers. [ABSTRACT FROM AUTHOR]

Introduction Repair of obstructive azoospermia caused by childhood herniorrhaphy may be difficult. Therefore, intracytoplasmic sperm injection using testicular sperm is performed. However, vasovasostomy combined with laparoscopic surgery is challenging. Case presentation A 42‐year‐old man underwent inguinal hernia repair at age 3. He had normal testicular size, azoospermia, normal hormone levels (follicle‐stimulating hormone, luteinizing hormone, and testosterone), absence of Y chromosome micro deletion, and karyotype:46XY, t(1:21)(p34.1:q22.3). He was diagnosed with obstructive azoospermia. Repeated intracytoplasmic sperm injections using testicular sperm resulted in miscarriages. Vasovasostomy combined with laparoscopic surgery was subsequently performed. Postoperative semen analysis result was almost normal. After intracytoplasmic sperm injection of ejaculated sperm, his wife got pregnant. Conclusion Even if patients have chromosomal abnormalities, performing microsurgical re‐anastomosis first is recommended. To our knowledge, this is the first case of a laparoscopy‐assisted vasovasostomy for post‐herniorrhaphy vas deferens obstruction in Japan.

Objective: The aim of this study was to evaluate whether the different vasovasostomy techniques can be performed using only the operating loupe in a rat model. The secondary aims were to evaluate the patency rate and inflammation of the vas deferens (VD) after contusion and the different vasovasostomy repair techniques. Methods: A total of 40 male rats were divided into 4 groups based on the type of surgery: 1. contusion of the VD; 2. cutting of the VD and vasovasostomy with absorbable sutures; 3. cutting and joining of the VD using absorbable sutures with an intraluminally situated lead fibre; and 4. cutting and joining of the VD using non-absorbable sutures with an intraluminally situated lead fibre. Ninety days after the surgery the VD was resected, patency and histopathological signs of inflammation in the VD were evaluated. Results: All vasovasostomy techniques were successfully performed in all animals using only the operating loupe. The patency rate was 100% in the subgroup with contusion. Differences in the patency rates were found among the subgroups with vasovasostomy (P=0.007). The patency rate was higher in the subgroup that underwent group 3. Compared with vasovasostomies, contusion was associated with lower rates of inflammation (P=0.02) and severe inflammation (P=0.003). No differences were found among the subgroups of vasovasostomy techniques. Conclusion: Contusion of the VD was not related to impairment in terms of patency. Vasovasostomy with an intraluminally situated lead fibre resulted in the highest patency rate among the standard vasovasostomy techniques.

ABSTRACT Objectives To validate an experimental non-animal model for training of vasectomy reversal. Materials and Methods The model consisted of two artificial vas deferens, made with silicon tubes, covered by a white resin, measuring 10 cm (length) and internal and external diameters of 0.5 and 1.5 mm, respectively. The holder of the ducts is made by a small box developed with polylactic acid, using a 3D print. The objective of the invention is to simulate the surgical field of vasovasostomy, when the vas deferens are isolated from other cord structures. For validation, it was verified the acquisition of microsurgical skills during its use, in a capacitation course with 5 urology residents from a Hospital of the region. Along the training sessions, it was analyzed the time (speed) of microsurgical sutures, and quantification of the performance using a checklist. Collected data were analyzed using de BioEstat®5.4 software. Results Medium time for the completion of microsurgical sutures improved considerably during the course, and reached a plateau after the third day of training (p=0.0365). In relation to the checklist, it was verified that during capacitation, there was significant improvement of the scores of each participant, that reached a plateau after the fourth day of training with the model (p=0.0035). Conclusion The developed model was able to allow the students that attended the course to gain skills in microsurgery, being considered appropriate for training vasectomy reversal.

The aim of this study was to evaluate and compare the efficiencies of unilateral and bilateral vasovasostomies as the vasectomy reversal procedures. A total of 95 patients with a history of bilateral vasectomy were evaluated. 42 of them had undergone unilateral surgery, and bilateral surgery had been done for the other 53 patients. Their information including the age, the time interval between the initial vasectomy to the reversal surgery and other underlying illnesses or medications was gathered. Patency rates in the unilateral and bilateral groups were 88.1% (38 patients) and 88.7% (48 patients), respectively, the difference of which was not statistically significant (p =.907). Successful pregnancies occurred in 22 (52.4%) and 29 (54.7%) patients, respectively, which did not show any statistically significant difference too (p =.713). Based on the multivariate logistic regression model, only the time interval between vasectomy and the reversal (duration of obstruction) was predictive of patency (OR = 1.112, p =.037). The outcomes of the unilateral and bilateral vasovasostomies in terms of patency and pregnancy rates were not significantly different. We suggest that performing unilateral, instead of bilateral, vasovasostomy can reduce the time of anaesthesia and surgery and save costs and consumables without having a significant negative impact on the surgical outcomes.

Background/aim: Iatrogenic vas deferens injury is one of the most serious complications of operations in the inguinal region. Vasovasostomy is performed as treatment. However, stenosis is common after vasovasostomy. Oligospermia or azoospermia may develop and result in infertility. This study aimed to investigate the effect of amniotic membrane on healing in vas deferens injuries. Materials and methods: Four groups consisting of 10 rats each were formed. No procedure was performed in Group-I. In Group-II, the left vas deferens was transected and left to spontaneous healing. In Group-III, the left vas deferens was transected, and end-to-end anastomosis was performed. In Group-IV, the left vas deferens was transected, end-to-end anastomosis was performed, and it was closed with a wrapping of amniotic membrane on the anastomosis line. Rats were sacrificed after 60 days, and each left vas deferens was evaluated. Lumen patency was checked by passing methylene blue through the vas deferens. Subsequently, the vas deferens was evaluated both macroscopically and histopathologically. Data were evaluated using SPSS version 21.0. p < 0.05 was considered statistically significant for all variables. Results: The anastomosis lines in Group-IV healed better than those in Group-III, and less stenosis was observed. There were differences between the groups in terms of luminal patency (p = 0.009), adhesions to surrounding tissues (p = 0.02) and separation of the ends of the vas deferens (p = 0.03). Conclusion: We observed improvement on luminal patency and histology of rat vas deferens injury after surrounding human amniotic membrane on the transected and repaired surface. Further studies are needed to apply this promising result on human beings. [ABSTRACT FROM AUTHOR]

The basic principles of vasal reconstruction have endured since their initial description over a century ago, yet the nuances and technical approaches have evolved. Prior to performing vasectomy reversal, the clinician should perform a focused history, physical and laboratory assessment, all of which are critical for patient counseling and preoperative planning. Operative success is contingent on appropriate intraoperative decision making and technical precision in completing a tension-free, watertight, and patent anastomosis. Outcomes of vasectomy reversal differ on the basis of the type of reconstruction required, reconstructive technique, and patient-specific factors. Here we review the indications, surgical techniques, and outcomes of vasectomy reversal. [ABSTRACT FROM AUTHOR]

Background Two-six percentage of vasectomized men will ultimately seek vasectomy reversal, which late stricture and obstruction after operation are relatively common. To find a method for improving vasovasostomy outcomes, we used intra-operative local mitomycin-C (MMC) preventing possible fibrosis and stricture. Materials and Methods In this randomized clinical trial, 44 patients were assigned to two groups randomly during a one-year study and the data of 40 patients were analyzed. The patients were followed up for 6 months after surgery. The case group (n=19) was treated by vasovasostomy with intra-operative local MMC. The control group (n=21) underwent standard vasovasostomy. Results Mean sperm count in MMC group was significantly higher than the controls. The sperm count of more than 20 million/ml was respectively 53% and 14% in MMC and control groups. In a subgroup where the interval between vasectomy and reversal was 5-10 years, post-reversal azoospermia was absent in MMC group, but 50% of the controls were still azoospermic. In addition, 80% of MMC group had more than 20 million/ml sperms, but all of the controls had less than 20 million/ml sperms. No significant complication was seen. Conclusion Intra-operative local MMC in vasovasostomy can be regarded as a safe and efficient technique which has several advantages including lower cost. Increase of sperm count is the main effect of local MMC applica- tion that is more prominent when the interval between vasectomy and reversal is 5-10 years (Registration number: IRCT2015092324166N1).

Objective: This study aimed to determine whether the length of the excised obstructed vas deferens at vasovasostomy (VV) performed for fertility is associated with semen parameters and/or pregnancy outcomes postoperatively. Material and methods: The patients who underwent a VV at our institution from September 2004 to December 2018 were contacted via questionnaire and a chart review was performed. Linear and logistic regression models were used to determine the associations between the length of the obstructed vas deferens removed and postoperative outcomes including sperm concentration, motility, and successful pregnancy after reversal. Results: A total of 83/170 questionnaires were returned. After exclusions, a total of 35 patients were included for analysis. The mean age of the patients at the time of surgery was 40.1 years and the mean time since vasectomy 9.3 years. The mean length of the obstructed vas deferens removed during VV was 2.25 cm. The longer the vas deferens segments removed, the more significant was the increase in sperm motility at 3 and 9 months postoperatively (p=0.011 and 0.008, respectively), but decreased sperm motility at 6 months (p=0.029). In 75.9% of the patients, sperm was present postoperatively, 23.2% achieved pregnancy through natural conception, and 55.8% achieved pregnancy using assisted reproductive techniques. There was no significant relationship between the length of the vas deferens removed and sperm concentration or pregnancy achieved after surgery. Conclusion: In this cohort, the length of the excised obstructed vas deferens at VV was associated with improved sperm motility at 3 and 9 months postoperatively but not with pregnancy outcomes.

Objective: To examine the relationship between antisperm antibody (ASA), pregnancy rates, and method of conception following vasectomy reversal, given that before and after vasectomy reversal, patients wonder if ASAs will prevent them from achieving pregnancy and American Urological Association vasectomy guidelines call for additional research to answer this question., Methods: We performed retrospective chart review and phone interview of patients who underwent vasectomy reversal at our institution from 1/1/2000 to 12/31/2018. We excluded patients who underwent vasectomy reversal for pain, or without postoperative semen analysis with ASA. We categorized patients as having low (<50%) or high (≥50%) ASA levels using the first postoperative semen analysis. Our primary outcome was pregnancy rate, including method of conception. Differences in pregnancy rates were tested using Fisher exact test., Results: Two hundred and four patients were chart reviewed. Median age at time of surgery was 40years and median obstruction interval was 7.3years. Median partner age was 32years. One hundred sixty-four (80%) patients underwent bilateral vasovasostomy. Eighty-five patients (42%) had low (<50%) ASA levels and 119 (58%) had high (≥50%) ASA levels. Sixty-seven patients completed phone interviews. Of 27 men with low ASA levels, 19 (70%) achieved a pregnancy with 16 (59%) spontaneous pregnancy. Of 40 men with high ASA levels, 30 (75%) achieved a pregnancy with 16 (40%) spontaneous pregnancy. The Fisher exact test P-value was .2., Conclusion: ASA levels are not associated with pregnancy rate or method of conception after vasectomy reversal. These findings can improve patient counseling before and after vasectomy reversal., Competing Interests: Declaration of Competing Interest James M.

Objective: Advancing paternal age is associated with impaired semen parameters. We sought to evaluate reproductive outcomes in men undergoing vasectomy reversal (VR) aged ≥50 vs <50 years.Methods: Reproductive outcomes (obstructive interval, female age, anastomosis type, post-VR total motile count (TMC), and pregnancy) after VR were assessed for men aged <50 and ≥50 years. Statistical analysis was performed using Kruskal-Wallis rank sum or Chi-squared tests. Multiple logistic regression was used to identify factors associated with achieving pregnancy.Results: A total of 2777 men <50 years and 353 men ≥50 years were included. The mean obstructive interval was 8.7 years less for men <50 years (8.9 vs 17.6 years, P <.001). The chances of needing a vasoepididymostomy were higher in men ≥50 years (19.5% vs 10.1%, P <.001). Post-VR total motile count was higher in men <50 years (59.3 vs 29.1 × 106/mL, P <.001). About 33.4% of men <50 years and 26.1% ≥50 years contributed to a pregnancy (P = .007). On multiple logistic regression analysis, obstructive interval <10 years (OR 1.295, P = .002) and female age <35 (OR 1.659, P <.001) were associated with achieving a pregnancy. A history of smoking was associated with decreased odds of achieving a pregnancy (OR 0.523, P <.001). Age <50 or ≥50 years at VR was not associated with achieving pregnancy (OR 0.852, P = 0.254).Conclusion: Compared to those ≥50 years, more men <50 years achieved a pregnancy after VR. However, on adjusted multivariable analysis, age at VR was not an independent predictor of achieving pregnancy. Shorter obstructive interval and female age were associated with achieving pregnancy, while a history of smoking was associated with decreased odds. Successful outcomes after VR can be achieved in older men, and VR should be considered in men ≥50 years, when performed by a trained microsurgeon. [ABSTRACT FROM AUTHOR]

Abstract Background In the era of improving assisted reproductive technology (ART), patients with obstructive azoospermia (OA) have 2 options: vasal repair or testicular sperm extraction with intracytoplasmic sperm injection. Vasal repair, including vasovasostomy (VV) and vasoepididymostomy (VE), is the only option that leads to natural conception. Methods This article reviews the surgical techniques, outcomes, and predictors of postoperative patency and pregnancy, with a focus on articles that have reported over the last 10 years, using PubMed database searches. Main findings The reported mean patency rate was 87% and the mean pregnancy rate was 49% for a patient following microscopic VV and/or VE for vasectomy reversal. Recently, robot‐assisted techniques were introduced and have achieved a high rate of success. The predictors and predictive models of postoperative patency and pregnancy also have been reported. The obstructive interval, presence of a granuloma, and intraoperative sperm findings predict postoperative patency. These factors also predict postoperative fertility. In addition, the female partner's age and the same female partner correlate with pregnancy after surgery. Conclusion In the era of ART, the physician should present and discuss with both the patient with OA and his partner the most appropriate procedure to conceive by using these predictors.

Objective: Microscope-assisted vasovasostomy (MAVV) is a standard procedure used to reverse vasectomies. Robotic surgery has been established primarily for technically demanding urological procedures and has also been recently implemented in male reproductive surgery. We aimed to review the current evidence of robot-assisted vasovasostomy (RAVV) and robot-assisted vasoepididymostomy (RAVE).Material and methods: We performed a systematic literature review using PubMed to identify relevant original articles. We identified 2017 records through database search, and after removing duplicates, 782 records remained for further analysis. Results: In total, 12 human and three animal studies were selected. Reported vasal patency rate ranges were 88%--100% for RAVVs and 55%--61% for RAVEs. The sperm count and postoperative pregnancy rates of RAVV ranged between 8.4 x 106--120 x 106 sperm/mL and 65%, respectively. Finally, procedure times in the human studies, recorded for extracorporeal RAVVs and RAVEs ranged from 97 to 238 minutes.Conclusion: Robot-assisted vasal reversal is feasible with similar patency rates as for the microsurgical approach and showing comparable outcomes. Additional benefits of this technique include improved vision and movement precision. [ABSTRACT FROM AUTHOR]

We assessed the contribution of microsurgical seminal reconstruction to achieving natural conception in conjunction with advanced assisted reproductive technologies. Ninety obstructive azoospermic subjects who underwent microsurgical seminal reconstruction were evaluated. Vasovasostomy (VV) was undertaken in 45 subjects whereas vasoepididymostomy (VE) in 45, respectively. VV was performed by employing a two microlayer anastomotic technique, whilst VE was undertaken using double needle longitudinal vaspepididymostomy (LIVE). Patency was achieved in 41 VV (91.1%), and 25 VE (55.6%) cases. In cases where patency was achieved, pregnancy and healthy delivery were recorded following natural intercourse in 7/41 (17.0%) VV, and in 7/25 (28.0%) VE cases. Where patency was not achieved, the use of cryopreserved sperm for intracytoplasmic sperm injection (ICSI), resulted in a healthy delivery in 4/4 (100%) VV and 14/21 (66.6%) in VE subjects. Although natural pregnancy was achieved only in a limited number of subjects treated (14/90; 15.6%), sperm harvested during surgery and cryopreserved for future ICSI use proved valuable, doubling the overall delivery rate (32/90; 36.6%). Surgical intervention is considered to be a useful technique in order to allow the possibility of a natural conception and by harvesting sperm at the same time contributes to the cost-effectiveness.

Objective: To examine whether men who were childless at the time of vasectomy sought consultation for fertility restoration.Methods: Retrospective chart review was performed to determine if patients without children at the time of vasectomy sought consultation for fertility restoration (defined as vasectomy reversal or sperm retrieval). If the patient had not been seen in our healthcare system within the previous 12 months, he was contacted by phone to determine whether he had sought consultation for fertility restoration.Results: Of 1656 men, 68 men (4.1%) were childless at the time of vasectomy. Fifteen patients were excluded as they were not followed in our hospital system and were unreachable by phone. Zero patients sought consultation for fertility restoration.Conclusion: Our single institution study demonstrated that no men who were childless at the time of vasectomy sought consultation for fertility restoration. Given that there are no other FDA approved methods for nonbarrier sterilization for males, men with no children at the time of vasectomy should receive the same AUA guideline-recommended counseling that men with children receive.
