The aim of this study was to validate the effectiveness of targeted microsurgical spermatic cord denervation (MSCD) of the trifecta nerve complex in comparison to traditional full MSCD with complete skeletonization of the spermatic cord in men with chronic orchialgia. Retrospective chart review was performed by a single fellowship-trained microsurgeon between 2011 and 2016. Patients had follow-ups at 6 weeks, 6 months, and 1 year postoperatively. Thirty-nine men with chronic orchialgia underwent full MSCD between 2011 and 2013. In July 2013, after the publication of an anatomic study with identification of Wallerian degeneration of the trifecta nerve complex in men with chronic orchialgia, the technique was changed to targeted MSCD. From July 2013 to March 2016, 43 men underwent targeted MSCD. When comparing the full MSCD group to the targeted MSCD group, there was no significant difference in resolution of pain (66.7% vs 69.8%, P = 0.88), no difference in partial relief of pain (17.9% vs 23.3%, P = 0.55), and no difference in failure to respond rates (15.4% vs 7.0%, P = 0.22) between the two groups. There was no difference in mean change of visual analog pain scale scores between the two groups (P = 0.27). Targeted MSCD had a shorter operative time (53 min vs 21 min, P = 0.0001). Targeted MSCD offers patients comparable outcomes to traditional full MSCD, with a shorter operative time, a less technically challenging surgery, and potentially less risk to cord structures which should be preserved.

PURPOSE: This review addresses different aspects of testicular torsion from the clinical perspective as well as the basic cellular and molecular events responsible for the post-torsion testicular changes and pathology, including tissue ischemia-reperfusion injury. MATERIALS AND METHODS: A review of all published literature on testicular torsion was performed by use of two search engines. RESULTS: Testicular torsion, or more correctly termed torsion of the spermatic cord, is a surgical emergency in order to salvage the testis. Its incidence is approximately 1 in 4,000 per annum. Testicular torsion must be treated promptly to avoid loss of the ipsilateral testis; however, even with torsion repair and gross testicular salvage, significant injury may still occur. CONCLUSIONS: The cellular and molecular mechanisms leading to ischemia-reperfusion injury are incompletely understood, and adjuncts to surgical treatment have received little attention. Understanding the cellular and molecular effects is important because 25% of males with a history of torsion may experience adult infertility. This review emphasizes current knowledge of basic science results and clinical outcomes of testicular torsion.

Purpose: Non-obstructive azoospermia (NOA) represents the persistent absence of sperm in ejaculate without obstruction, stemming from diverse disease processes. This survey explores global practices in NOA diagnosis, comparing them with guidelines and offering expert recommendations. Materials and Methods: A 56-item questionnaire survey on NOA diagnosis and management was conducted globally from July to September 2022. This paper focuses on part 1, evaluating NOA diagnosis. Data from 367 participants across 49 countries were analyzed descriptively, with a Delphi process used for expert recommendations. Results: Of 336 eligible responses, most participants were experienced attending physicians (70.93%). To diagnose azoospermia definitively, 81.7% requested two semen samples. Commonly ordered hormone tests included serum follicle-stimulating hormone (FSH) (97.0%), total testosterone (92.9%), and luteinizing hormone (86.9%). Genetic testing was requested by 66.6%, with karyotype analysis (86.2%) and Y chromosome microdeletions (88.3%) prevalent. Diagnostic testicular biopsy, distinguishing obstructive azoospermia (OA) from NOA, was not performed by 45.1%, while 34.6% did it selectively. Differentiation relied on physical examination (76.1%), serum hormone profiles (69.6%), and semen tests (68.1%). Expectations of finding sperm surgically were higher in men with normal FSH, larger testes, and a history of sperm in ejaculate. Conclusions This expert survey, encompassing 367 participants from 49 countries, unveils congruence with recommended guidelines in NOA diagnosis. However, noteworthy disparities in practices suggest a need for evidence-based, international consensus guidelines to standardize NOA evaluation, addressing existing gaps in professional recommendations.

There have been many significant scientific advances in the diagnostics and treatment modalities in the field of male infertility in recent decades. Examples of these include assisted reproductive technologies, sperm selection techniques for intracytoplasmic sperm injection, surgical procedures for sperm retrieval, and novel tests of sperm function. However, there is certainly a need for new developments in this field. In this review, we discuss advances in the management of male infertility, such as seminal oxidative stress testing, sperm DNA fragmentation testing, genetic and epigenetic tests, genetic manipulations, artificial intelligence, personalized medicine, and telemedicine. The role of the reproductive urologist will continue to expand in future years to address different topzics related to diverse questions and controversies of pathophysiology, diagnosis, and therapy of male infertility, training researchers and physicians in medical and scientific research in reproductive urology/ andrology, and further development of andrology as an independent specialty.

Purpose: Non-obstructive azoospermia (NOA) is a common, but complex problem, with multiple therapeutic options and a lack of clear guidelines. Hence, there is considerable controversy and marked variation in the management of NOA. This survey evaluates contemporary global practices related to medical and surgical management for patients with NOA. Materials and Methods: A 56-question online survey covering various aspects of the evaluation and management of NOA was sent to specialists around the globe. This paper analyzes the results of the second half of the survey dealing with the management of NOA. Results have been compared to current guidelines, and expert recommendations have been provided using a Delphi process. Results: Participants from 49 countries submitted 336 valid responses. Hormonal therapy for 3 to 6 months was suggested before surgical sperm retrieval (SSR) by 29.6% and 23.6% of participants for normogonadotropic hypogonadism and hypergonadotropic hypogonadism respectively. The SSR rate was reported as 50.0% by 26.0% to 50.0% of participants. Interestingly, 46.0% reported successful SSR in <10% of men with Klinefelter syndrome and 41.3% routinely recommended preimplantation genetic testing. Varicocele repair prior to SSR is recommended by 57.7%. Half of the respondents (57.4%) reported using ultrasound to identify the most vascularized areas in the testis for SSR. One-third proceed directly to microdissection testicular sperm extraction (mTESE) in every case of NOA while others use a staged approach. After a failed conventional TESE, 23.8% wait for 3 months, while 33.1% wait for 6 months before proceeding to mTESE. The cut-off of follicle-stimulating hormone for positive SSR was reported to be 12–19 IU/mL by 22.5% of participants and 20–40 IU/mL by 27.8%, while 31.8% reported no upper limit. Conclusions This is the largest survey to date on the real-world medical and surgical management of NOA by reproductive experts. It demonstrates a diverse practice pattern and highlights the need for evidence-based international consensus guidelines.
