The advantages seem to include increased optical magnification, improved surgical efficiency, absent tremor, and similar outcomes with standard methods. This chapter covers robotic microsurgical application and techniques for: robot-assisted vasectomy reversal with vasovasostomy and vasoepididymostomy, varicocelectomy, microsurgical testicular sperm extraction, and targeted denervation of the spermatic cord.

A cohort study of men infected with COVID-19 for presence of SARS-CoV-2 virus in their semen.

Introduction: Whether severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) can be detected in semen and transmitted sexually is a vital question that has, thus far, been inconclusive. Prior studies, with limited numbers, have included men in various stages of infection with most in the recovery phase of the illness. The timing of test results and severity of illness has made recruiting study participants a significant challenge.

Targeted Microsurgical Denervation of the Spermatic Cord for Chronic Orchialgia: the Current Standard of Care.

Purpose Of Review: This paper reviews the pathophysiology, current literature, techniques for full microsurgical denervation (MDSC) and targeted microsurgical denervation (TMDSC) of the spermatic cord, and outcomes for these treatment options for patients with chronic scrotal content pain (CSCP) or orchialgia.

Recent Findings: Significant reduction in pain (77-100%) is reported across various studies for CSCP patients with minimal patient morbidity. The testicular atrophy/loss risk is less than 1%.

Hydrodissection for improved microsurgical denervation of the spermatic cord: prospective blinded randomized control trial in a rat model.

Microsurgical denervation of the spermatic cord (MDSC) can provide up to an 86% improvement in pain in patients with chronic orchialgia (CO) who have failed conservative management. Failures in MDSC could be due to small diameter nerves (≤1 mm) left behind on the spermatic cord. The objective of this study was to assess if hydrodissection (HD) of the spermatic cord after MDSC could decrease the number of residual nerve fibers without compromising blood flow.

Management of Chronic Orchialgia: Challenges and Solutions - The Current Standard of Care.

Methods: A review of the literature was performed.

Male Oxidative Stress Infertility (MOSI): Proposed Terminology and Clinical Practice Guidelines for Management of Idiopathic Male Infertility.

Despite advances in the field of male reproductive health, idiopathic male infertility, in which a man has altered semen characteristics without an identifiable cause and there is no female factor infertility, remains a challenging condition to diagnose and manage. Increasing evidence suggests that oxidative stress (OS) plays an independent role in the etiology of male infertility, with 30% to 80% of infertile men having elevated seminal reactive oxygen species levels. OS can negatively affect fertility a number of pathways, including interference with capacitation and possible damage to sperm membrane and DNA, which may impair the sperm's potential to fertilize an egg and develop into a healthy embryo.

Salvage Ultrasound-guided Targeted Cryoablation of The Perispermatic Cord For Persistent Chronic Scrotal Content Pain After Microsurgical Denervation Of The Spermatic Cord.

Robot-assisted microsurgery in male infertility and andrology.

Use of the operative microscope marked a new era for microsurgery in male infertility and andrology in the 1970s. More than a decade has passed since the initial description of the first robotic-assisted microsurgical vasovasostomy. Large single-center series have recently been published on robotic-assisted microsurgery for vasectomy reversal, especially in the past few years.

Medical management of male infertility in the absence of a specific etiology.

Idiopathic male infertility can be diagnosis in approximately one-third of infertile males. The empirical medical treatment with or without assisted reproductive techniques appears common in male infertility practice. This type of management can be classified as hormonal treatment including gonadotropins, antiestrogens, and aromatase inhibitors and support with antioxidant supplements such as carnitine, lycopene, glutathione, and vitamin E.

Robotic microsurgery optimization.

The increased application of the da Vinci robotic platform (Intuitive Surgical Inc.) for microsurgery has led to the development of new adjunctive surgical instrumentation. In microsurgery, the robotic platform can provide high definition 12×-15× digital magnification, broader range of motion, fine instrument handling with decreased tremor, reduced surgeon fatigue, and improved surgical productivity.

Robotic-assisted microsurgery for an elective microsurgical practice.

Robotic-assisted microsurgery can be utilized for either intracorporal or extracorporeal surgical procedures. Three-dimensional high-definition magnification, a stable ergonomic platform, elimination of physiologic tremor, and motion scaling make the robotic platform attractive for microsurgeons for complex procedures. Additionally, robotic assistance enables the microsurgeon to take microsurgery to challenging intracorporeal locations in a minimally invasive manner.

Robotically assisted microsurgery: development of basic skills course.

Robotically assisted microsurgery or telemicrosurgery is a new technique using robotic telemanipulators. This allows for the addition of optical magnification (which defines conventional microsurgery) to robotic instrument arms to allow the microsurgeon to perform complex microsurgical procedures. There are several possible applications for this platform in various microsurgical disciplines.

Update in the evaluation of the azoospermic male.

Approximately 1% of all men in the general population suffer from azoospermia, and azoospermic men constitute approximately 10 to 15% of all infertile men. Thus, this group of patients represents a significant population in the field of male infertility. A thorough medical history, physical examination and hormonal profile are essential in the evaluation of azoospermic males.
