Abstract
CONTEXT Contraception is a major global health issue, which is still dominated by female contraception. Developments in male contraception could help redistribute the contraceptive burden. METHODS A literature search was carried out to review the existing options and the criteria for optimal contraception, to establish the principles of a male pre-contraception consultation, and to review the various research avenues with their advantages and disadvantages. RESULTS The new male contraception options are detailed, whether hormonal (androgen therapy, combination of progestins and testosterone) or non-hormonal, particularly thermal, with current results and avenues for improvement. Condom use and vasectomy remain the only 2 validated options. The recent development of minimally invasive vasectomy without the need for a scalpel and of occlusion techniques has simplified the procedure, minimised the risk of complications (pain, haematomas, post-vasectomy pain syndrome) and improved efficacy. The issues of regret and the possibility of repermeabilisation are also raised. CONCLUSION The question of male contraception will become increasingly important in consultations with urologists. The urologist will have to inform the patient, as required by law, before the vasectomy is performed, and provide the best possible advice on the technique, which will often be minimally invasive without the need for a scalpel. New reversible options should also broaden the range of options available on a routine basis, with a view to gradually moving towards contraceptive equity.

Abstract
BACKGROUND At a time when increasing attention is being paid to the limitations and risks of in vitro fertilisation techniques, surgeries to improve male fertility are attracting growing interest. METHODS Systematic review based on a Pubmed search of surgeries to improve male fertility. RESULTS Vasovasostomy (VV) gives patency rates of 70-97% and pregnancy rates of 30-76%. Vasoepididymostomy (VE) gives patency rates of 80-84%, with pregnancy rates of 40-44%. The duration of obstruction and the age of the partner are 2 predictive parameters for the occurrence of a natural pregnancy. In cases of obstructive azoospermia due to pelvic obstruction (prostatic cyst, obstruction of the ejaculatory ducts), several surgical procedures may be proposed. Transurethral resection of the ejaculatory ducts leads to an improvement in sperm parameters in 63-83% of patients, with spontaneous pregnancy occurring in 12-31% of cases. Microsurgical cure of varicocele by the subinguinal route is a benchmark technique with recurrence rates of less than 4%. It improves live birth and pregnancy rates, both naturally and by in vitro fertilization, as well as sperm count, motility and DNA fragmentation rates. CONCLUSION Whenever possible, the urologist should present the surgical options for improving male fertility to the ART team and to the couple, discussing the benefit/risk balance of the operation as part of a personalized approach.

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.

Abstract
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
Given the nature of the multiple causes of male infertility, some of them are «reversible» and can be managed with a surgical procedure to recover, in some cases, the fertilizing capacity of the male reproductive tract. With appropriate use of diagnostic tools and clinical judgement, the physician can identify the ideal candidates for these procedures. Together with the expertise and experience of the surgeon, these treatments can manage to resolve the barrier, and men may become fertile again. In this chapter, we will review some of the most commonly used surgical procedures for the treatment of male infertility and make a brief description of their technical details.

Abstract
This study aimed to evaluate a simplified vasovasostomy procedure that shortens the operative time. This was a retrospective (non-randomized) study of men who underwent bilateral vasectomy and consulted for vasovasostomy (02/2014-08/2016). Eight interrupted sutures were used for one-layer full-thickness vasal anastomosis over a 20 or 22 G catheter temporarily inserted in the lumen of the anastomotic site as a stent. Control patients underwent double-layer vasovasostomy. The surgery was significantly shorter in the one-layer group (n = 23) (62 ± 8 vs. 133 ± 15 min, P < 0.001 vs. the two-layer group, (n = 19)). There was no difference in patency between the two groups (95.7 vs. 94.7%, P > 0.999). There was one case of epididymitis in each group. There were no complications like bleeding, scrotal hematoma, hydrocele, or infection. Low-power microscopic one-layer vasovasostomy with stent was simple and had a short operation time. The patency could be similar to that of two-layer vasovasostomy, but prospective studies are necessary for confirmation.

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 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
Purpose Microsurgical vasovasostomy is associated with high patency and pregnancy rates, but is difficult and requires significant effort and time to learn. Therefore, we assessed a simplified loupe-assisted vasovasostomy method using a Prolene stent. Materials and Methods The medical records of 82 patients who underwent loupe-assisted vasovasostomy with a Prolene stent by a single surgeon between January 2004 and December 2015 were reviewed. The association between the vasal obstructive interval (VOI) and the success rate was evaluated. Results The average age at the time of vasovasostomy was 39.8 years (range, 29~57 years). The mean VOI was 6.6 years (range, 1~19 years). The mean operation time was 87.0 minutes (range, 55.0~140.0 minutes). The overall patency and natural pregnancy rates were 90.2% and 45.1%, respectively. The success rate decreased as time after vasectomy increased (odds ratio, 0.869; 95% confidence interval, 0.760~0.993; p=0.039). The cases were divided into 2 groups according to the mean VOI: group A (>7 years) and group B (≤7 years), with 31 cases (37.8%) and 51 cases (62.2%), respectively. The patency and pregnancy rates of group A were 80.6% and 51.6%, respectively, while those of group B were 96.1% and 41.2%, respectively. Conclusions Loupe-assisted vasovasostomy using a Prolene stent is a safe and effective method.

Abstract
OBJECTIVE To evaluate the application of a microsurgical two-layer anastomosis technique in the treatment of failed vasectomy reversal. METHODS A microsurgical two-layer anastomosis was used in a series of 24 patients with confirmed anastomotic obstruction after previous vasectomy reversal. The patients were followed up for 9 months to 6 years, and the efficacy of the procedure was evaluated by regular seminal analysis and pregnancy records. The results were compared with those obtained from 34 patients who had received primary microsurgical vasovasostomy in our hospital using the same microsurgical technique. RESULTS In the treatment group for failed vasectomy reversal patients, the postoperative patency rate was 87.5% (21/24), resulting in a pregnancy rate of 54.2% (13/24). In primary reversal group, the postoperative patency rate was 94.1% (32/34), resulting in a pregnancy rate of 67.6% (23/34). Both the patency and pregnancy rate were not significantly different between these two groups. CONCLUSIONS The microsurgical vasovasostomy and vasoepididymostomy provided satisfactory patency rate and natural pregnancy rate for patients with a previous failed vasectomy reversal, which is comparable with the results of patients who had undergone primary procedure.

Abstract
OBJECTIVE To investigate the association between the presence of sperm in the vasal fluid during vasectomy reversal (VR) and postoperative patency. METHODS We performed a systematic review and meta-analysis of the English-language literature reporting on the association between the presence of sperm in the intraoperative vasal fluid (ie, whole or parts vs none) and patency (ie, patent or not) after microsurgical vasovasostomy for men with obstructive azoospermia due to vasectomy. Odds ratios (OR) and 95% confidence intervals were calculated to quantify the strength of the association reported by each study. Meta-analysis was performed using a random-effects model. RESULTS Four case series and 2 retrospective cohort studies of a total of 1293 eligible patients were identified. The mean age at VR was 37.8 years, and the mean obstructive interval was 7.1 years. The unadjusted OR of postoperative patency was 4.1 times higher (95% confidence interval, 2.3-7.3) given the presence of intravasal sperm or sperm parts as opposed to their absence at the time of VR (Q = 3.4; df = 5; P = .6; I(2) = 22%). The pooled OR should be interpreted with caution as only the 2 retrospective cohort studies reported meaningful data on this association. Because of inconsistent reporting, analysis of other vasal fluid characteristics (eg, consistency) and outcomes (eg, pregnancy) was not possible. CONCLUSION The presence of whole sperm or sperm parts in the vasal fluid during VR is positively associated with postoperative patency. Our review highlights the poor methodological quality of existing evidence and underscores the need for more thorough follow up and higher standards of reporting in future studies.
