The worldwide human population growth rate, which doubled during the 20th century, as well as the increasing fertility rate, have contributed to an increasing and evolving emphasis on contraception. With respect to female contraceptive methods, many have been developed, marketed, and are widely available. In contrast, male contraception has been limited to condoms, which pose logistical challenges, and vasectomy, which is largely irreversible. The use of sound to achieve effective and safe male contraception is a promising but unproven hypothesis...

BACKGROUND: From 2014-2016, our clinical practice progressively incorporated several male infertility and andrology procedures performed under local anesthesia, including circumcision, hydrocelectomy, malleable penile prostheses, orchiectomy, penile plication, spermatocelectomy, testicular prostheses, varicocelectomy, vasectomy reversal (VR), and testicular and microepididymal sperm aspiration (TESE/MESA). Given the observed outcomes and potential financial and logistical benefits of this approach for surgeons and patients, we sought to describe our initial experience...

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...

Dane Johnson, Jay I Sandlow
According to data from the National Study of Family Growth, vasectomy is utilized by 6-13% of American couples for their form of contraception. Physician surveys have shown that over 500,000 men undergo vasectomies per year, and more than 75% of vasectomies are performed by urologists. This chapter provides a brief history of vasectomy, as well as recommendations for preoperative counseling, an overview of the modified no-scalpel vasectomy technique, and a brief description of the complications of vasectomy...

Because rhesus macaques (Macaca mulatta) are prolific breeders, overpopulation can be problematic in both research and feral populations. Currently, the most effective contraceptive methods are hormonal control in female macaques and vasectomies in males. These methods each come with innate challenges, the foremost being the alteration of necessary hormonal patterns. In this study, we assessed the use of zinc gluconate neutralized with arginine as a novel, nonsurgical alternative to male contraception in 12 rhesus macaques...

Tubal ligation is the modal form of family planning among American women aged 30 and older. As the preference for tubal ligation over cheaper, lower risk and more reliable methods, such as vasectomy, has puzzled experts, a theoretical approach that explains this preference would be useful. The present study investigates the high prevalence of voluntary sterilization among American women from the perspective of life history theory, arguing that the trade-offs between investing in current and future offspring will favour tubal ligation when women cannot obtain reliable male commitment to future parental investment...

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...

BACKGROUND: Even though several studies comparing vasectomy and cardiovascular disease (CVD) risk have been reported, most are small series with conflicting results. However, the extent of the risk is still uncertain. We therefore explored whether an association exists between vasectomy and CVD incidence and mortality. METHODS: We searched PubMed, Embase, Web of Science, and Cochrane Library databases for relevant studies published before January 2017. Multivariate adjusted odds ratio (OR) and associated 95% confidence intervals (CIs) and those by subgroups were extracted and pooled using random-effects models...

BACKGROUND: Vasectomy has been implicated as a risk factor for prostate cancer in multiple epidemiologic studies over the past 25 years. Whether this relationship is causal remains unclear. This study examines the association between vasectomy and prostate cancer in the Prostate Lung Colorectal and Ovarian (PLCO) cancer screening trial, which randomized men to usual care or annual prostate cancer screening. METHODS: We performed a retrospective analysis of 13-year screening and outcomes data from the PLCO trial...

INTRODUCTION AND AIM: Surgical vasectomy remains the gold standard for fertility control in men. Endoluminal occlusion of the seminal ducts, thus avoiding an external incision, may become an appealing alternative to this approach. As our group has shown, nontraumatic endoscopic inspection of the seminal ducts is feasible in the human cadaver. We investigated the feasibility and reliability of occlusion using several commercially available medical sealing agents in the porcine vas deferens (VD)...

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...

Vasectomy is the most effective form of sterilization for men. With approximately 500,000 vasectomies performed each year in the United States, 1-2% of these patients will experience chronic testicular pain for greater than three months after the procedure. Post-vasectomy pain syndrome (PVPS) is diagnosis of exclusion, and may be caused by direct damage to spermatic cord structures, compression of nerves in the spermatic cord via inflammation, back pressure from epididymal congestion, and perineural fibrosis...

Chronic orchialgia is a vexing condition defined as chronic or intermittent scrotal pain lasting at least three months that significantly interferes with daily activities. There are currently no guidelines regarding the diagnosis and management of this condition despite it being the cause of 2.5-4.8% of urologic clinic visits. Men often present with chronic orchialgia in their mid to late 30s, although the condition can present at any age. A broad differential diagnosis of chronic orchialgia includes epididymitis, testicular torsion, tumors, obstruction, varicocele, epididymal cysts, hydrocele, iatrogenic injury following vasectomy or hernia repair, and referred pain from a variety of sources including mid-ureteral stone, indirect inguinal hernia, aortic or common iliac artery aneurysms, lower back disorders, interstitial cystitis, and nerve entrapment due to perineural fibrosis; approximately 25-50% of chronic orchialgia is idiopathic in nature...

Post-vasectomy pain syndrome (PVPS) is a rare, but devastating outcome following vasectomy. Given the widespread utilization of vasectomy for permanent contraception, with more than 500,000 procedures performed annually in the United States, it can be a significant challenge for both patients and providers. Vasectomy reversal is a surgical option for men who fail conservative or medical management. Despite improvements in technique, vasectomy carries some inherent risks making pre-procedure counseling regarding the risks of PVPS paramount...

Chronic orchialgia is one of the most common complaints seen in the urologists office and has traditionally been considered a very difficult diagnostic and therapeutic challenge for the clinician. First line management of chronic orchialgia is conservative treatment; however, in men who fail conservative therapy, surgical intervention may be indicated. Microsurgery has been the mainstay for surgical treatment of chronic orchialgia, but the implementation of robotics to microsurgery lends itself particularly to surgical treatment of chronic orchialgia...

This review describes necrospermia, its diagnosis, causes and management. Sperm vitality is commonly assessed in the laboratory of reproductive biology, with the eosin test or with the hypo-osmotic swelling test. Necrospermia is defined by a percentage of living spermatozoa inferior to 58%, and can be related to male infertility. Several pathological mechanisms may be involved and can be classified either in testicular causes (hyperthyroidism, local hyperthermia, varicocele), or post-testicular causes (epididymal necrospermia, dysregulation of seminal plasma, adult polycystic kidney disease, vasectomy reversal, anti-sperm antibodies) or both (infection, toxic, age, spinal cord injury)...
