Global Practice Patterns in the Evaluation of Non-Obstructive Azoospermia: Results of a World-Wide Survey and Expert Recommendations.

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.

Global Practice Patterns and Variations in the Medical and Surgical Management of Non-Obstructive Azoospermia: Results of a World-Wide Survey, Guidelines and Expert Recommendations.

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.

Does Varicocele Repair Improve Conventional Semen Parameters? A Meta-Analytic Study of Before-After Data.

PURPOSE: The purpose of this meta-analysis is to study the impact of varicocele repair in the largest cohort of infertile males with clinical varicocele by including all available studies, with no language restrictions, comparing intra-person conventional semen parameters before and after the repair of varicoceles. MATERIALS AND METHODS: The meta-analysis was performed according to PRISMA-P and MOOSE guidelines. A systematic search was performed in Scopus, PubMed, Cochrane, and Embase databases. Eligible studies were selected according to the PICOS model (Population: infertile male patients with clinical varicocele; Intervention: varicocele repair; Comparison: intra-person before-after varicocele repair; Outcome: conventional semen parameters; Study type: randomized controlled trials [RCTs], observational and case-control studies). RESULTS: Out of 1,632 screened abstracts, 351 articles (23 RCTs, 292 observational, and 36 case-control studies) were included in the quantitative analysis. The before-and-after analysis showed significant improvements in all semen parameters after varicocele repair (except sperm vitality); semen volume: standardized mean difference (SMD) 0.203, 95% CI: 0.129-0.278; p<0.001; I²=83.62%, Egger's p=0.3329; sperm concentration: SMD 1.590, 95% CI: 1.474-1.706; p<0.001; I²=97.86%, Egger's p<0.0001; total sperm count: SMD 1.824, 95% CI: 1.526-2.121; p<0.001; I²=97.88%, Egger's p=0.0063; total motile sperm count: SMD 1.643, 95% CI: 1.318-1.968; p<0.001; I²=98.65%, Egger's p=0.0003; progressive sperm motility: SMD 1.845, 95% CI: 1.537%-2.153%; p<0.001; I²=98.97%, Egger's p<0.0001; total sperm motility: SMD 1.613, 95% CI 1.467%-1.759%; p<0.001; l2=97.98%, Egger's p<0.001; sperm morphology: SMD 1.066, 95% CI 0.992%-1.211%; p<0.001; I²=97.87%, Egger's p=0.1864. CONCLUSIONS: The current meta-analysis is the largest to date using paired analysis on varicocele patients. In the current meta-analysis, almost all conventional semen parameters improved significantly following varicocele repair in infertile patients with clinical varicocele.

[Use of implants to treat male urinary incontinence]. / Einsatz von Implantaten zur Versorgung der männlichen Harninkontinenz.

Treatments for benign and malignant pathologies of the prostate can compromise urine control. Urinary incontinence (UI) affects the quality of life of patients and limits their ability to carry out usual activities. The degree of impact of UI is variable and the associated discomforts make patients seek treatment for it. At the center of the management of urinary incontinence in men are surgical interventions that seek to replace the affected sphincter function through implants. The artificial urinary sphincter since its development in the 1970s has been considered the standard of treatment for UI in men. More recently artificial sphincter and slings have been shown to be effective in a selected group of incontinent men. The goals of surgical treatment of incontinence include the preservation of bladder function, the ability to improve the strength of the urinary sphincter, and to reduce or eliminate urine leakage, and thereby improve the quality of life. The aim of the article is to present various implants for the correction of male urinary incontinence.

[Psychosocial consequences of urinary incontinence - tabooed and undertreated: a systematic review]. / Psychosoziale Folgen der Harninkontinenz ­ tabuisiert und unterversorgt ­ eine systematische Übersichtsarbeit.

BACKGROUND: Urinary incontinence is a significant health problem that can affect both women and men of all ages. It is not a life-threatening condition, but symptoms can have a strong impact on the physical, psychological and social well-being of those affected. Existing literature mainly reports on incontinent patients over 65 years of age. Studies about stress and effects of incontinence in younger patients are limited. Incontinence is a social taboo subject, with few sufferers seeking professional help for reasons of shame. Some incontinent individuals seek support when symptoms worsen and further reduce their quality of life. This study aims to explain which psychosocial stresses and effects of urinary incontinence in adults are described in the literature and how those affected experience these. METHODS: A systematic literature search was performed for the years 2007 to 2022 in the databases CINAHL, Cochrane Database of Systematic Reviews via OvidSP, PsycINFO via OvidSP and PubMed. In addition to the research in the databases, a hand search was carried out on the internet and via the reference lists of the included and critically evaluated articles. RESULTS: Incontinence affects the entire life of those affected. Incontinent patients suffer from low self-esteem and shame. They reduce physical activities, have fewer social contacts and experience problems in working life. The condition often leads to impairments in partnership and sexuality. Younger patients have a higher level of suffering than older patients. SUMMARY: In order to contribute to removing the taboo on urinary incontinence, health professionals should be made aware of the living situation of incontinent patients. Patient education is given high priority and strategies need to be developed to help those affected to cope.

Genitourinary manifestations of sickle cell disease.

OBJECTIVES: Sickle cell disease is one of the most common hereditary diseases, and migration trends and cross breeding have increased its incidence in Europe. While much has been published about the disease, there are few reviews in the literature dealing with its manifestations in the genitourinary system. METHODS: We conducted a comprehensive review, using as our main instrument the PubMed online database, on recent advances in knowledge of the pathophysiology and urological, nephrological, and andrological manifestations of the disease. RESULTS: Manifestations include sickle cell nephropathy, enuresis, nocturia, hematuria, priapism, renal medullary carcinoma, and infarctions and necrosis in various organs of the genitourinary system. CONCLUSIONS: The characteristics of this important disease and the multisystemic spectrum it covers make knowledge of its genitourinary manifestations necessary.

[Azoospermia should not be given as the result of vasectomy]. / La azoospermia no debería ofrecerse como resultado de la vasectomia.

OBJECTIVES: Vasectomy is a surgical method of male contraception. Azoospermia is offered as result of the technique and this is not always attained, resulting in legal matters. The purpose of this study is to know the number of semen samples needed to discharge a patient after intervention. To identify sperm count on semen analysis at time of discharge. METHODS: Retrospective study of men who underwent vasectomy in a 15-month period with a 2 year follow up. Consecutive semen analyses up to 5 samples were measured at 2 to 3 months interval in all men who had persistence of spermatozoa. RESULTS: 618 men were intervened, 106 did not bring semen to the laboratory (17%), 2 (0.39%) presented motile sperm and were considered a failure of the technique and excluded. 510 men completed controls. 316 (61.9%) were azoospermic in the first sperm analysis, 74 (14.5%) in the second, 27 (5.2%) in the third, 6 (1.2%) in the fourth and one (0,.%) in the fifth analysis. The remaining 86 men (16.8%) had persistence of immotile sperm in the ejaculate and were less than 100,000/ml. No pregnancy was reported during 2 years follow up or after. CONCLUSIONS: Five or more semen analysis can be made after the surgery. Persistence of immotile sperm in the ejaculate is frequent and may exist for a long period afterwards. Immotile sperm count of 100,000/ml or less should be accepted as result of the procedure. The patient should be informed about the fact that persistent immotile sperm can be found in his semen. In the informed consent azoospermia should not be a concern as it is frequent to find immotile sperm in the ejaculate and this is an acceptable issue. As with other contraceptive methods, vasectomy should be offered as a safe method although clearly stating that the possibilities of failure do exist.

La azoospermia no debería ofrecerse como resultado de la vasectomía / Azoospermia should not be given as the result of vasectomy

OBJETIVOS: La vasectomía es un método quirúrgico de contracepción masculina. Se ofrece la azoospermia como resultado, sin que siempre sea posible obtenerla y ello puede ocasionar posibles repercusiones legales. El propósito de este estudio es conocer el número de seminogramas necesarios para conseguir la azoospermia después de la intervención. METODOS: Análisis retrospectivo de hombres a los cuales se les realizó la vasectomía durante un período de 15 meses y con un seguimiento posterior de 2 años. Se realizaron seminogramas consecutivos, más de cinco, con intervalos de 2 a 3 meses en cada uno de los que se obtenía persistencia de espermatozoides. RESULTADOS: Se intervinieron 618 hombres,106 fueron descartados por no aportar muestras de semen (17%) y 2 (0.39%) por presentar espermatozoides móviles, considerándose fallo de la técnica. 510 siguieron el control completo. 316 (61.9 %) resultaron azoospérmicos en el primer seminograma, 74 (14.5%) en el segundo, 27 (5.2%) en el tercero, 6 (1.2 %) en el cuarto y 1 (0.2%) en el quinto seminograma. Los 86 (16.8%) restantes siguieron presentando espermatozoides en el eyaculado más allá del quinto exámen seminal. Los espermatozoides persistentes fueron todos inmóviles e inferiores a 100,000/ml. No se reportaron casos de embarazos en los dos años de seguimiento. CONCLUSIONES: El número de análisis post quirúrgico puede ser mayor de cinco. La presencia de espermatozoides inmóviles en el eyaculado después de la vasectomía es frecuente, incluso después de largos períodos posteriores a la cirugía. Recuentos espermáticos iguales o inferiores a 100,000/ml e inmóviles deberían considerarse aceptables como objetivo del método. Se debería informar acerca de la posible persistencia de espermatozoides inmóviles en el semen. En el consentimiento no debería constar la azoospermia como resultado de la intervención ya que es frecuente encontrar espermatozoides inmóviles y ser igualmente aceptable. Al igual que otros, se debe ofrecer la vasectomía como otros métodos contraceptivos eficaz, pero con posibilidad de fallos (AU)
