Sperm granulomas: Predictive factors and impacts on patency post vasectomy reversal.

Andrologia 2022 May 6:e14439. Epub 2022 May 6.

International Center for Vasectomy Reversal, Tucson, Arizona, USA.

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. Read More

Vasovasostomy and vasoepididymostomy: indications, operative technique, and outcomes.

Fertil Steril 2021 06 27;115(6):1384-1392. Epub 2021 Apr 27.

Department of Urology, Northwestern University Feinberg School of Medicine, Chicago, Illinois. Electronic address:

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. Read More

Challenges in completing a successful vasectomy reversal.

Andrologia 2021 Jul 18;53(6):e14066. Epub 2021 Apr 18.

Department of Urology, University of Miami, Miami, FL, USA.

Although a wide array of interventions exist for men seeking fertility after vasectomy, up to 6% of them will elect for a vasectomy reversal. While the widespread adoption of telemedicine promises convenience and improved access, lack of ability to do a physical examination may hinder appropriate counselling. Although vasectomy reversal is successfully completed in most of the men either with a vasovasostomy or a vasoepididymostomy, there could be various reasons for the inability to successfully complete the operation.

3D digital image microscope system-assisted vasovasostomy and vasoepididymostomy in rats.

Asian J Androl 2021 Jul-Aug;23(4):396-399

Shanghai General Hospital, Shanghai Jiao Tong University School of Medicine, Shanghai 200080, China.

Optimal vision and ergonomics are essential factors contributing to the achievement of good results during microsurgery. The three-dimensional (3D) digital image microscope system with a better 3D depth of field can release strain on the surgeon's neck and back, which can improve outcomes in microsurgery. We report a randomized prospective study of vasoepididymostomy and vasovasostomy using a 3D digital image microscope system (3D-DIM) in rats. Read More

The effect of trainee involvement on surgical outcomes and complications of male infertility surgical procedures.

Andrologia 2020 Oct 19;52(9):e13719. Epub 2020 Jun 19.

Institute of Urology, University of Southern California, Los Angeles, CA, USA.

In this study, we sought to determine the effect of trainee (resident or fellow physician) involvement in male infertility surgical procedures on patient surgical outcomes and complications. The American College of Surgeons National Surgical Quality Improvement Program (NSQIP) database was retrospectively reviewed for fertility surgical procedures from 2006 to 2012. The procedures included were as follows: epididymectomy, spermatocelectomy, varicocelectomy ± hernia repair, ejaculatory duct resection, vasovasostomy, vasoepididymostomy and 'unlisted procedure male genital system' (to capture sperm retrieval procedures).

Vasovasostomy and vasoepididymostomy: Review of the procedures, outcomes, and predictors of patency and pregnancy over the last decade.

Reprod Med Biol 2018 Oct 22;17(4):343-355. Epub 2018 May 22.

Department of Urology Graduate School of Medicine Chiba University Chiba Japan.

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. Read More

[Microsurgical management of obstructive azoospermia: Progress and prospects].

Zhonghua Nan Ke Xue 2018 Jul;24(7):579-288

Center for Male Reproductive Medicine and Microsurgery, Department of Urology, Cornell Institute for Reproductive Medicine, Weill Cornell Medicine of Cornell University, New York Presbyterian University Hospitals for Columbia and Cornell, New York, NY 10065, USA.

In the past two decades, with the rapid development of assisted reproductive technology and particularly the technological advances in male infertility microsurgery, many obstructive azoospermia-related infertile couples can now acquire the chances of natural pregnancy via reconstruction of the seminal tract. This article highlights the latest advances in surgical reconstruction of the seminal tract for the treatment of obstructive azoospermia, such as the application of laparoscopic and robotic techniques, with a discussion on microsurgical epididymal sperm aspiration and preservation, potential use of absorbable sutures or the bio-suture tape for microsurgical anastomosis in the management of obstructive azoospermia.

The Kinetics of Sperm Return and Late Failure Following Vasovasostomy or Vasoepididymostomy: A Systematic Review.

J Urol 2019 02;201(2):241-250

Center for Male Reproductive Medicine and Microsurgery, Cornell Institute for Reproductive Medicine, Department of Urology, Weill Cornell Medicine, New York, New York.

Purpose: Vasovasostomy and vasoepididymostomy are technically challenging microsurgical reconstructive procedures necessary for men with obstructive azoospermia at the level of the vas deferens or epididymis. Patency rates following vasovasostomy or vasoepididymostomy have been widely described in the literature. However, few reports have discussed the timing of sperm return to the ejaculate after reconstruction as well as the proportion of men in whom late failure develops following vasovasostomy or vasoepididymostomy.

Vasectomy reversal: a clinical update.

Asian J Androl 2016 May-Jun;18(3):365-71

Department of Urology, University of Virginia, Charlottesville, VA 22908-0422, USA.

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.

Pre-operative risk factors associated with need for vasoepididymostomy at the time of vasectomy reversal.

Andrology 2016 Jan 11;4(1):160-2. Epub 2015 Dec 11.

Department of Urology, Oregon Health & Sciences University, Portland, OR, USA.

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. Read More

The evolution of vasectomy reversal.

Curr Urol Rep 2015 Jun;16(6):40

Baylor College of Medicine, Houston, TX, USA,

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.
