STUDY QUESTION: Should we opt for surgical vasovasostomy or IVF/ICSI after a vasectomy? SUMMARY ANSWER: Both options reveal acceptable pregnancy rates though the time to pregnancy was significantly lower in the immediate IVF/ICSI group. WHAT IS KNOWN ALREADY: About 7.4% of men regret their vasectomy and express a renewed child wish. The choice between surgical vasectomy reversal or ICSI remains difficult for patients and their fertility specialist...

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...

Varicocele is commonly observed in male partners of infertile couples. The surgical ligation of varicoceles under microscopy can be safely performed by a skilled andrologist with most patients subsequently experiencing an improvement in semen quality. This is the first case in which obstructive azoospermia occurred after high inguinal varicocelectomy. The vas deferens was disrupted near the internal inguinal ring by fibrous tissue. A vasovasostomy was performed and semen parameters subsequently recovered.

Of all patients who have vasectomies performed in the United States, upwards of 6% will pursue a vasectomy reversal. Currently, the gold-standard reversal procedure is a microscopic vasovasostomy utilizing either a one or two-layer vasal anastomosis. Unfortunately, most urologists do not perform these procedures as they require extensive training and experience in microsurgery. The objective of our study was to evaluate the feasibility and success rate of robot-assisted vasovasostomy performed at our institution...

Objective: To evaluate the efficacy and safety of microsurgical crossover vasovasostomy in treating complicated obstructive azoospermia. Methods: The data of 14 patients with complicated obstructive azoospermia treated with microsurgical crossover vasovasostomy were reviewed from October 2012 to March 2016.Ten of them underwent microsurgical crossover vasovasostomy. Intraoperative exploration revealed that 2 patients had vas deferens injury and contralateral testicular atrophy or epididymal obstruction due to previous hernia repair; 7 patients had obstruction of intracorporeal vas deferens on one side and epididymal obstruction on the other side; the other 1 patient had unilateral vasal obstruction with contralateral epididymal obstruction...

BACKGROUND: Spermatozoa acquire their fertilizing ability and forward motility properties during epididymal transit. Our knowledge of gamete physiology is based on studies conducted in laboratory and domestic species; our knowledge of these processes in humans is limited. Medical indications for assisted reproductive technologies (ART) have progressed to include male infertility. Surgical procedures allow collection of spermatozoa from all along the human excurrent ducts, and the former have been used with some success in reproductive medicine...

INTRODUCTION: Anti sperm antibodies (ASA) can present in serum and semen and they may lead to impair the sperms function leading to infertility. The precise mechanism of generation of these antibodies is yet to be discovered. AIM: This study was performed to determine the prevalence of anti-sperm antibodies (ASA) in patients with unexplained infertility. The study was initiated also to explore the possible factors that may associate with ASA formation and how ASA status is associated with pregnancy rates after going with in vitro fertilization - intracytoplasmic sperm injection (IVF-ICSI)...

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...

The absence of sperm in the ejaculate after vasectomy reversal is commonly caused by failure to recognize and subsequently bypass epididymal or proximal vasal obstruction at the time of vasectomy reversal. If intra-operative proximal obstruction is suspected, vasoepididymostomy (VE) is recommended rather than vasovasostomy (VV). We sought to calculate the associated risk of needing VE, rather than VV with time from original vasectomy (obstructive interval) using a large cohort of vasectomy reversal patients...

PURPOSE: Approximately 2% to 6% of men undergoing vasectomy will ultimately have it reversed. Cost is a major consideration for patients and providers with regard to vasovasostomy. Opportunities for cost savings for vasectomy reversal lie in the reduction of variable costs, namely operative time and materials used. In this study we determine the cost benefits of a modified 1-layer vasovasostomy compared to a formal 2-layer vasovasostomy. MATERIALS AND METHODS: A retrospective analysis was performed of a single surgeon experience of vasectomy reversals performed from 2010 to 2015...

In the USA, about 500,000 vasectomies are performed each year, with up to 6% of men requesting reversal. The technique of vasectomy reversal has evolved from macrosurgical to the implementation of both microscopic and robotic technologies. The very earliest attempts at vasectomy reversal, the vasoepididymostomy and vasovasostomy, have remained central in the treatment of male infertility and will continue to be so for years to come. As seen throughout its history, urological microsurgery has consistently implemented advanced techniques and state-of-the art technology in its craft, and its continued refinement will allow for even more favorable outcomes in the lives of patients seeking restoration of fertility following vasectomy...

We evaluated pre-operative and intraoperative factors associated with successful patency following bilateral microsurgical vasovasostomy (VV). We retrospectively reviewed the charts of 1331 men who underwent bilateral VV by two surgeons between 2006 and 2013. Vasal fluid was examined intraoperatively for gross quality (i.e., clear or opaque and creamy/thick) and for the presence of spermatozoa on microscopy (i.e., whole spermatozoa, sperm fragments, or azoospermia). Post-operative patency was assessed by semen analysis or patient report of conception...
