Microsurgical Management of Male Infertility: Compelling Evidence That Collaboration with Qualified Male Reproductive Urologists Enhances Assisted Reproductive Technology (ART) Outcomes. J Clin Med 2022; 11:jcm11154593. [PMID: 35956208 PMCID: PMC9369943 DOI: 10.3390/jcm11154593] [Citation(s) in RCA: 4] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/06/2022] [Revised: 08/02/2022] [Accepted: 08/04/2022] [Indexed: 11/16/2022] Open
Abstract
A male factor plays a significant role in a couple's reproductive success. Today, advances in reproductive technology, such as intracytoplasmic sperm injection (ICSI), have allowed it to be possible for just a single sperm to fertilize an egg, thus, overcoming many of the traditional barriers to male fertility, such as a low sperm count, impaired motility, and abnormal morphology. Given these advances in reproductive technology, it has been questioned whether a reproductive urologist is needed for the evaluation and treatment of infertile and subfertile men. In this review, we aim to provide compelling evidence that collaboration between reproductive endocrinologists and reproductive urologists is essential for optimizing a couple's fertility outcomes, as well as for improving the health of infertile men and providing cost-effective care.

[PMID: 35524153 PMCID: PMC9541413 DOI: 10.1111/and.14439] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/18/2022] [Revised: 03/06/2022] [Accepted: 03/18/2022] [Indexed: 12/04/2022] Open
Abstract
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
OBJECTIVE To explore the primary options available to men who desire fertility after a vasectomy. DESIGN Literature review. SETTING University of Miami Miller School of Medicine. PATIENT(S) Men with a previous vasectomy now seeking fertility. INTERVENTION(S) The two main options to achieve paternity for men following vasectomy include vasectomy reversal (VR) and surgical sperm retrieval with subsequent in vitro fertilization (IVF). MAIN OUTCOME MEASURE(S) We reviewed and compared the important considerations for men deciding between these 2 options, including: obstructive interval, female partner age, antisperm antibodies, male partner age, female infertility factors, and cost. RESULT(S) Both VR and IVF represent reasonable options for the couple seeking fertility after vasectomy. Specific circumstances may favor one modality over another, depending on obstructive interval, possible female fertility factors, female partner age, male partner age, and cost. In the absence of insurance coverage, VR is often more cost-effective than IVF. Alternatively, when a female factor may contribute to infertility in addition to vasectomy, IVF is often the better choice. Antisperm antibodies are unlikely to contribute to infertility following a successful VR. CONCLUSION(S) VR or surgical sperm retrieval with IVF are reasonable options for couples seeking children after vasectomy. Pregnancy rates for both options are overall similar, so prior to pursuing either option, a thorough discussion with a reproductive urologist who possesses microsurgical skills in VR and a reproductive endocrinologist with expertise in IVF is imperative. Making a final choice through shared decision-making while considering these points is ideal.

Abstract
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.

Abstract
Iatrogenic disease is defined as illness caused by diagnostic procedures or treatment given by health care professionals. More recently described treatment complications involving the genitourinary tract include newly recognized variants of renal carcinoma in the setting of dialysis/end-stage renal disease, treatment effect in genitourinary carcinomas, and medical renal disease caused by drug therapies, including immunotherapy. The objective of this review is to cover iatrogenic inflammatory diseases, pseudotumors and tumors of the kidney, bladder, prostate, testis and paratestis of most interest to surgical pathologists. For this reason, disease caused by the following will not be covered: iatrogenic glomerulonephritis, self-inflicted injury including the introduction of foreign bodies, surgical error, drugs of abuse and herbal medications, and iatrogenic disease in the transplant setting including ischemia/reperfusion injury. Emphasis is placed upon commonly encountered diseases in order to ensure that the review is of utility to practicing pathologists. The clinical context, pathophysiology and histopathology of each disease entity are covered.

Ethylene dimethane sulfonate (EDS) ablation of Leydig cells in adult rat depletes testosterone resulting in epididymal sperm granuloma: Testosterone replacement prevents granuloma formation. Reprod Biol 2018; 19:89-99.

Abstract
Sperm granuloma may develop in the epididymis following vasectomy or chemical insults. Inflammation due to sperm granuloma causes abdominal and scrotal pain. Prolonged and persistent inflammation in the epididymis due to sperm granuloma may lead to infertility. Extravasation of germ cells into the interstitium of epididymis following damage of the epididymal epithelium is one of the primary reasons for sperm granuloma-associated pathology. Since testosterone is vital for the maintenance of epididymal epithelium, we investigated the pathology of sperm granuloma and its relationship with testosterone. Adult rats were treated with a Leydig cell-specific toxicant ethylene dimethane sulfonate (EDS) to eliminate testosterone. At 7 days post-EDS, disrupted epididymal epithelium and sperm granuloma were observed in the caput epididymis. Sperm granuloma and caput were collagen-filled indicating fibrosis. Numerous round apoptotic cells were localized inside the caput lumen and dispersed through the sperm granuloma. Tnp1 (round spermatid marker) was significantly higher in the epididymis of the EDS-treated group compared to controls suggesting the apoptotic cells were round spermatids. Increases in CD68+ macrophages and T cells (CD4 and CD8) support an inflammatory immune infiltration in post-EDS epididymis. However, testosterone replacement following EDS prevented the sperm granuloma-associated pathology. We suggest that the immune response in the sperm granuloma may be due to the increased numbers of apoptotic round spermatids or other testicular tissue components that may be released, in addition to the regression of epididymal epithelium due to testosterone loss. Thus, testosterone replacement prevents EDS-induced sperm granuloma and ameliorates sperm granuloma-associated pathology.

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.

Abstract
Vasectomy is the method of contraception chosen by more than 500,000 American men annually, and by upwards of 8% of married couples worldwide. However, following the procedure, nearly 20% of men express the desire for children in the future, and approximately 2–6% of American men will ultimately undergo vasectomy reversal (VR). VR is a complex microsurgical procedure. Intraoperative decision-making, surgical technique, and postoperative management are each critical step in achieving high success rates. The aim of this article is to provide a detailed description of the operative and perioperative procedures employed by surgeons performing VRs.

Abstract
Vasectomy is a safe and effective method of contraception used by 42–60 million men worldwide. Approximately 3%–6% of men opt for a vasectomy reversal due to the death of a child or divorce and remarriage, change in financial situation, desire for more children within the same marriage, or to alleviate the dreaded postvasectomy pain syndrome. Unlike vasectomy, vasectomy reversal is a much more technically challenging procedure that is performed only by a minority of urologists and places a larger financial strain on the patient since it is usually not covered by insurance. Interest in this procedure has increased since the operating microscope became available in the 1970s, which consequently led to improved patency and pregnancy rates following the procedure. In this clinical update, we discuss patient evaluation, variables that may influence reversal success rates, factors to consider in choosing to perform vasovasostomy versus vasoepididymostomy, and the usefulness of vasectomy reversal to alleviate postvasectomy pain syndrome. We also review the use of robotics for vasectomy reversal and other novel techniques and instrumentation that have emerged in recent years to aid in the success of this surgery.

Abstract
This is a meta-analysis to compare the results between laminoplasty and laminectomy followed by fusion for the patients with multilevel cervical compressive myelopathy. An extensive search of literature was performed in MEDLINE, Embase, the Cochrane library, CNKI, and WANFANG. The following outcome measures were extracted: the Japanese Orthopaedic Association (JOA) scores, cervical curvature index (CCI), visual analog scale (VAS), cervical lordosis (C2-7), complications, blood loss, and operation time. Data analysis was conducted with RevMan 5.3 and STATA 12.0. A total of 23 studies comprising 774 and 743 patients treated with laminoplasty and laminectomy followed by fusion, respectively, were included in the final analysis. The pooled analysis showed that there was no significant difference in preoperative JOA scores [P = 0.89], postoperative JOA scores [P = 0.13], JOA scores improvement rate [P = 0.27], preoperative CCI [P = 0.15], postoperative CCI [P = 0.14], preoperative VAS [P = 0.41], postoperative VAS [P = 0.52], preoperative cervical lordosis (C2-7) [P = 0.46], postoperative cervical lordosis (C2-7) [P = 0.67], total complications [P = 0.07], axial pain [P = 0.94], and blood loss [P = 0.51]. However, there were significant difference in operation time (WMD = -19.57 [-32.11, -7.02], P = 0.002) and C5 palsy (OR = 0.26 [0.15, 0.44], P < 0.001). As compared with laminectomy followed by fusion, expansive laminoplasty showed no significant differences in JOA scores, CCI, ROM, VAS, cervical lordosis (C2-7), axial pain, total complications, and blood loss, but shorter operation time and fewer C5 palsy.

Abstract
OBJECTIVE To perform a systematic review and meta-analysis of the published literature evaluating vasovasostomy for vasectomy reversal outcomes. METHODS We conducted a review of English language articles describing results of microscopic vasovasostomy for vasectomy reversal. Two reviewers independently examined the studies for eligibility and evaluated data from each study. Meta-analysis was performed using a random effects model. RESULTS Thirty-one studies with 6633 patients met inclusion criteria. Mean patient age at time of vasectomy reversal was 38.9 years with a mean obstructive interval of 7.2 years. The mean postprocedure patency and pregnancy rates weighted by sample size were 89.4% and 73.0%, respectively. A meta-analysis comparing an obstructive interval (OI) of <10 years to an OI of at least 10 years duration produced a pooled incidence ratios (IR; meta-IR) of 1.17 (95% confidence interval [CI], 1.09-1.25) for patency and 1.24 (95% CI, 1.12-1.38) for pregnancy. Incidence of patency for modified 1-layer technique was similar to that after a 2-layer procedure with a meta-IR of 1.04 (95% CI, 1.00-1.08). Because of a small number of relevant studies, a meta-analysis for other predictors of success such as sperm granuloma, quality of vasal fluid, and female factors was not feasible. CONCLUSION We found no statistically significant difference in vasovasostomy outcomes when comparing the impact of single vs multilayer anastomoses. Patients with an OI <10 years showed higher patency and pregnancy rates compared with those with an OI ≥10 years. Uniform definitions of patency are necessary to characterize success and standardize outcome reporting.

Abstract
This review highlights the evaluation and treatment of men who have undergone vasectomy and desire vasectomy reversal to father children. For surgeons offering this treatment, the appropriate evaluation and treatment are crucial for acceptable outcomes. Although variations on surgical approaches have evolved over the years, one constant is the need for a high level of training and skill in microsurgical techniques.

Abstract
Obstructive azoospermia is a common cause of male infertility and can result from infection, congenital anomalies, or iatrogenic injury. Microsurgical vasal reconstruction is a suitable treatment for many cases of obstructive azoospermia, although some couples will require sperm retrieval paired with in-vitro fertilization. The various causes of obstructive azoospermia and recommended treatments will be examined. Microsurgical vasovasostomy and vasoepididymostomy will be discussed in detail. The postoperative patency and pregnancy rates for surgical reconstruction of obstructive azoospermia and the impact of etiology, obstructive interval, sperm granuloma, age, and previous reconstruction on patency and pregnancy will be reviewed.

Abstract
About 3-6% of vasectomized men requested vasectomy reversal, for various reasons. Vasal patency (VP) is an important surrogate outcome of vasectomy reversal. This article reviews the impact of surgical skills, surgical approaches, intraoperative vasal fluid characteristics and the length of obstructive interval on VP. Based on the best available evidence, the rate of patency is related to the operative frequency of the surgeons, with better results obtained by surgeons who perform the operations at least 10 times annually. Microsurgical vasovasostomy is the preferred technique for durable good results. One-layer vasovasostomy and two-layer vasovasostomy seem to be equal with regard to VP. The rate of patency following vasovasostomy in the convoluted vas and vasovasostomy in the straight vas is comparable. The patency rate is high in men with clear intraoperative vasal fluid in at least one vas. VP is still high among patients with a long obstructive interval. In conclusion, surgical skills and intraoperative vasal fluid characteristics are the most important predictors of VP. Postoperative semen quality and the age of the female partner determine the chance of spontaneous conception in these couples.

Abstract
PURPOSE Up to 6% of men who undergo vasectomy may later undergo vasectomy reversal. Most men require vasovasostomy but a smaller subset requires epididymovasostomy. Outcomes of epididymovasostomy depend highly on specialized training in microsurgery and, if predicted preoperatively, might warrant referral to a specialist in this field. We created a nomogram based on preoperative patient characteristics to better predict the need for epididymovasostomy. MATERIALS AND METHODS We evaluated patients who underwent primary vasectomy reversal during a 5-year period. Preoperative and intraoperative patient data were collected in a prospectively maintained database. We evaluated the ability of age, years since vasectomy, vasectomy site, epididymal fullness and granuloma presence or absence to preoperatively predict the need for epididymovasostomy in a given patient. The step-down method was used to create a parsimonious model, on which a nomogram was created and assessed for predictive accuracy. RESULTS Included in the study were 271 patients with a mean age of 42 years. Patient age was not positively associated with epididymovasostomy. Mean time from vasectomy to reversal was 9.7 years. Time to reversal and a sperm granuloma were selected as important predictors of epididymovasostomy in the final parsimonious model. The nomogram achieved a bias corrected concordance index of 0.74 and it was well calibrated. CONCLUSIONS Epididymovasostomy can be preoperatively predicted based on years since vasectomy and a granuloma on physical examination. Urologists can use this nomogram to better inform patients of the potential need for epididymovasostomy and whether specialist referral is needed.
