Vasectomy is an elective surgical sterilization procedure for men that is intended to obstruct or remove a portion of both vas deferens, thereby preventing sperm from moving from the testes to the ejaculatory ducts. Although intended for permanent sterilization, vasectomy can be reversed in most men seeking to restore their fertility due to a change in marital status or reproductive goals. The ...

Vasectomy reversal involves either vasovasostomy (VV) or epididymovasostomy (EV), and rates of epididymal obstruction and EV increase with time after vasectomy. However, as older vasectomies may not require EV for successful reversal, we hypothesized that sperm production falls after vasectomy and can protect the system from epididymal blowout. Our objective was to define how the need for EV at...

PURPOSE Assisted reproductive technology (ART), including in vitro fertilization and intracytoplasmic sperm injection, is routinely used to treat male factor infertility. Because of the success of ART, the optimal method to achieve pregnancy with male infertility is controversial. Two examples in which ART competes with traditional male infertility treatments are varicocelectomy and vasectomy r...

Abstract Study question A systematic review of current literature evaluating different techniques in performing vasovasostomy (VV) and vasoepididymostomy (VE) including robotic-assisted minimally invasive their outcomes Summary answer Macrosurgical, microsurgical robot-assisted have evidence for use vasectomy reversal. The robotic assistance may benefit over standard techniques. What is known al...

The growing popularity of vasectomy as a primary form of birth control has also created an increasing demand for vasectomy reversal (VR). The advent of IVF with intracytoplasmic sperm injection after sperm retrieval has given couples an alternative to traditional VR. Although VR remains the most cost-effective and natural way to conceive after vasectomy, competing interests and market pressures...

To establish the prevalence of vasitis nodosa in patients who had undergone vasectomy segments of vas deferens resected from 40 patients at the time of vasectomy reversal were examined histologically and immunohistochemically. The findings were correlated with clinical history and postoperative outcome. Controls comprised segments of normal vas deferens excised at vasectomy. Twenty of the 40 va...

During recent years many urologists have been convinced of the advantages of robot-assisted, minimally invasive urological procedures. Because microscope-assisted vasovasostomy is a rather uncommon procedure, most urologists lack microsurgical experience. Use of the da Vinci robotic system (Intuitive Surgical, Mountain View, CA, USA) virtually eliminates the microsurgical challenge of tremor, l...

Abstract Introduction Microscopic-assisted vasovasostomy is a well described procedure used to manage obstructive azoospermia. Intra-abdominal azoospermia poses challenge and various techniques have been described, including both open minimally invasive approaches. The wide-spread adoption of robotics within urology has led multiple reports robotic-assisted vasovasostomy, which offers feasible ...

A male factor is the only cause of infertility in 30% to 40% of couples. Most causes of male infertility are treatable, and the goal of many treatments is to restore the ability to conceive naturally. Varicoceles are present in 15% of the normal male population and in approximately 40% of men with infertility. Varicocele is the most common cause of male infertility that can be corrected surgica...
