Abstract
INTRODUCTION Varicocoele is commonly encountered in males with infertility. Studies have shown that varicocoele repair (surgery or embolisation) can improve the rate of subsequent pregnancy. In Australia, there have been no studies assessing the cost of varicocoele embolisation and current practice is based on international data. This study aimed to assess the cost of varicocoele embolisation and estimate the treatment cost per pregnancy. METHODS Retrospective cost-outcome study of patients treated by embolisation between January 2018 and 2023. A bottom-up approach was used to calculate procedure costs whereas a top-down approach was used to calculate costs for all other patient services, including direct and indirect costs. To calculate cost per pregnancy, costs were adjusted according to existing published data on the rate of pregnancy after embolisation. RESULTS Costing data from 18 patients were included, of median age 33.5 years (range 26-60) and median varicocoele grade 2.5 (range 1-3). All patients had unilateral treatment, most commonly via right internal jugular (16 patients, 89%) and using a 0.035″ system (17 patients, 94%). The median cost for the entire treatment including procedural, non-procedural, ward and peri-procedural costs was AUD$2208.10 (USD$1405 or EUR€1314), range AUD$1691-7051. The projected cost to the healthcare system per pregnancy was AUD$5387 (USD$3429 or EUR€3207). CONCLUSION Total varicocoele embolisation cost and the cost per-pregnancy were lower than for both embolisation and surgical repair in existing international studies. Patients undergoing varicocoele treatment should have the option to access an interventional radiologist to realise the benefits of this low-cost pinhole procedure.

Abstract
BACKGROUND Ultrasonography is the gold standard imaging method for scrotal investigation. Colour Doppler ultrasonography, contrast-enhanced ultrasonography and sonoelastography allow sonographers to assess size, echotexture, vascular features and stiffness of the scrotal organs and abnormalities. Scrotal ultrasonography has been used to investigate male reproductive health, scrotal pain, masses and trauma. However, ultrasonography thresholds/classifications used to distinguish normal and pathologic features of the scrotal organs have changed over time, and have not yet been fully standardized. OBJECTIVES To evaluate historical trends for the standards in scrotal ultrasonography: what was, what is and what will be normal. METHODS An extensive Medline search was performed identifying the most relevant studies in the English language from inception to date. RESULTS We provide here (i) a brief overview of the history of ultrasonography, (ii) current indications for scrotal ultrasonography and (iii) previous and current normal values, cut-offs and classifications of the main colour-Doppler ultrasonography parameters/characteristics of the scrotal organs, as derived from recent guidelines and evidence-based studies. In addition, we report recommendations and the clinical utility of contrast-enhanced ultrasonography and sonoelastography. Finally, we discuss critical issues needing further evidence and future directions to fill in the current gaps. DISCUSSION Several studies on scrotal ultrasonography are available. However, guidelines/recommendations dealing with specific ultrasonography applications have been published only in recent years. More recently, the European Academy of Andrology published evidence-based scrotal colour-Doppler ultrasonography reference ranges/normative parameters derived from a cohort of healthy, fertile men. In addition, a standardization of the methodology to evaluate qualitative and quantitative colour-Doppler ultrasonography parameters was reported. Other international societies reported indications, methodological standards, clinical utility and limitations of contrast-enhanced ultrasonography and sonoelastography. CONCLUSIONS To date, colour-Doppler ultrasonography normative values for the scrotal organs are available. However, a wide international consensus on assessment and classification of several ultrasonography parameters is still lacking. An alignment of the world societies on these issues is advocated.

Abstract
BACKGROUND Varicocoele-associated stressors, such as hypoxia and heat, can damage cell function and viability, and some exosomal biomarkers released from impaired cells may reflect the cell status in testis. OBJECTIVES To find if seminal exosomal microRNAs can reflect the Sertoli cell function in varicocoele. MATERIALS AND METHODS Experimental left varicocoele rat model was established (n = 24), and patients with different grades of varicocoele (n = 104) were enrolled. Primary rat Sertoli cells were isolated with enzymatic hydrolysis. Exosomes were isolated from primary rat Sertoli cells, rat epididymis tissue, and human seminal plasma with polymer-based precipitation method. Exosomal microRNAs were quantified with qPCR. Inhibin-B was detected with enzyme immunoassay. The correlation analysis between microRNA and inhibin-B was evaluated with Spearman's correlation. RESULTS We screened 12 previously reported hypoxia-responsive microRNAs in the primary rat Sertoli cells and found that 4 exosomal microRNAs increased significantly in response to in vitro hypoxia treatment (P < .05). Of the 4 microRNAs, only miR-210-3p was upregulated in the rats with experimental varicocoele (P < .01). In the patients with varicocoele, we found that seminal exosomal miR-210-3p significantly increased in patients with grade II and III varicocoele (P < .01), and miR-210-3p negatively correlated with sperm count (P < .01) and seminal inhibin-B expression (r = -0.39, P < .01). For the 30 patients with microsurgical varicocelectomy, the operation notably decreased miR-210-3p (P < .01). DISCUSSION AND CONCLUSION Seminal exosomal miR-210-3p may be a novel, sensitive, and non-invasive biomarker of Sertoli cell damage in varicocoele.

Abstract
BACKGROUND Varicocoele-induced male infertility potentially involves oxidative stress. Although varicocoelectomy is recommended for varicocoele patients presenting abnormal semen findings, no pharmacotherapeutic methods currently exist. We have recently developed a silicon-based agent that produces hydrogen by the reaction with water. OBJECTIVES This study aimed to investigate the therapeutic effects of oral administration of a Si-based agent on varicocoele rat. MATERIALS AND METHODS Twenty-one rats were divided into four groups: varicocoele + normal diet (n = 5), varicocoele + Si-based agent-supplemented diet (n = 6), sham + normal diet (n = 5), and sham + Si-based agent-supplemented diet (n = 5). All rats were euthanized four weeks after surgery. RESULTS The mean left epididymal sperm motility was 74.4% in the sham group, 72.3% in the sham + Si group, 57.6% in the varicocoele group, and 66.9% in the varicocoele + Si group. Epididymal sperm motility was significantly lower in the varicocoele group, but was significantly higher upon Si-based agent ingestion (P < .01). The mean left testicular weight, Johnsen's score, and left epididymal sperm concentration did not differ significantly between groups. The 8-OHdG concentration and DNA fragmentation rate were significantly increased in the varicocoele group, but were significantly decreased in the Si-based agent intake group (P < .01). Additionally, the IVF rate was significantly lower in the varicocoele group (26.3%) compared with the sham group (73.4%; P < .01), and was significantly higher in the varicocoele + Si group (51.8%) compared with the varicocoele group (P < .05), indicating that the Si-based agent improves IVF rates. DISCUSSION AND CONCLUSION Oral intake of the silicon-based agent improves epididymal sperm motility and in vitro fertilization rates through hydrogen production and subsequent reduction of oxidative stress. Considering the lack of effective noninvasive methods, this Si-based agent is potentially applicable for treating varicocoele-induced abnormal semen parameters.

Abstract
BACKGROUND Varicocoele (VCL), one of the main causes of male subfertility, negatively affects testicular function. Due to limited access to human testicular tissue, animal model studies have been used to evaluate molecular and, recently, epigenetic changes attributed to pathophysiology induced by VCL. OBJECTIVES This review aims to provide an update on the latest findings regarding the link between VCL-induced biochemical stress and molecular changes in germ cells and spermatozoa. Endocrine and antioxidant status, testicular chaperone-specific hemostasis failure, altered testicular ion balance, metabolic disorders, and altered carbon cycling during spermatogenesis are among the many features that will be presented. DISCUSSION Literature review coupled with our own findings suggests that ionic imbalance, hypoxia, hyperthermia, and altered blood flow could lead to severe chronic oxidative and nitrosative stress in patients with VCL leading to defective spermatogenesis and impairment of the integrity of all sperm cell components and compartments down to the epigenetic information they carry. CONCLUSION Since oxidative stress is an important feature of the reproductive pathology of VCL, therapeutic strategies such as the administration of appropriate antioxidants could be undertaken as a complementary non-invasive treatment line.

Abstract
BACKGROUND Trends of male factor causes of couples' infertility over time have been poorly investigated. OBJECTIVE We investigated trends in the causes of pure male factor infertility (MFI) throughout the last 10 years in a tertiary-referral academic andrology center. MATERIAL AND METHODS Baseline characteristics at first presentation from a cohort of 1647 consecutive male factor infertility patients belonging to primary infertile couples between 2008 and 2018 have been comprehensively collected over time. Seven major causes of male factor infertility were identified: varicocoele; history of cryptorchidism; hypogonadism (primary and secondary); obstructive azoospermia; genetic abnormalities; other causes (large group including the remnant conditions of known causes); and idiopathic infertility. Rates of different male factor infertility causes over the study period were analyzed. Multivariable logistic regression models tested the likelihood of male factor infertility causes over time. Estimated trends were explored graphically. RESULTS Of all, varicocoele was found in 615 (37.3%), cryptorchidism in 124 (7.5%), genetic abnormalities in 61 (3.7%), hypogonadism in 165 (10%), obstructive conditions in 55 (3.3%), other causes in 129 (7.8%) patients, and idiopathic infertility in 498 (30.3%) patients, respectively. Over time, a reduction in the proportions of cryptorchidism and varicocoele (all P < 0.001) cases was observed, along with an increase in the proportions of hypogonadism, other causes of MFI and idiopathic cases (all P ≤ 0.01). Rates of genetic and obstructive cases remained stable. The observed trends were confirmed at logistic regression models. DISCUSSION AND CONCLUSIONS A decreasing trend in the proportions of varicocoele and cryptorchidism at first presentation was observed over the last 10 years; conversely, the proportions of idiopathic cases, hypogonadal patients, and infertile men presenting with other male factor infertility causes significantly increased over the same time frame at a single tertiary-referral academic andrology center.

Abstract
The pathophysiology of varicocele remains to be unknown. Several genetic factors have been implicated in varicocele etiopathogenesis. We studied the relationship between NOS3 c.894G>T, c.786T>C and 4b/a polymorphisms to varicocele risk and their prognostic value as regards improvement of the post-operative seminal parameters &/or seminal malonaldehyde levels. The three NOS3 polymorphisms were evaluated in 100 patients with varicocele and 100 healthy subjects by RT-PCR. Seminal plasma MDA level was measured pre-operatively and 3 months after varicocelectomy by the thiobarbituric acid method. The GT, TT, TC and bb genotypes of NOS3 polymorphism were more commonly observed in varicocele patients (30%, 9%, 28% and 70% respectively) compared to normal controls (12%, 0%, 10% and 50% respectively). The mean percentage of post-varicocelectomy seminal MDA reduction was highest with the GT genotype (p < .001). Genotypes GT+TT, TC and bb were associated with varicocele occurrence in our patients. The T (c.894G>T), C (c.786T>C) and b (NOS3 intron 4 VNTR) alleles were significantly associated with varicocele occurrence in our cohort of patients. We also report a better response regarding the reduction of seminal MDA after varicocelectomy with the GT and ba genotypes.

Abstract
BACKGROUND Varicocoele is a swollen bulge of the pampiniform venous plexus inside the scrotum. It is also considered one of the causes of infertility in males. It has been demonstrated that hesperidin has remarkable pharmacological potentials, including antioxidant, anti-inflammatory, antimicrobial, and anticarcinogenic effects. OBJECTIVE The present study aimed to evaluate the protective effect of hesperidin on varicocoele-induced testicular tissue damage and oxidative stress in the testicles of adult male rats. MATERIALS AND METHODS Animals were assigned into the following groups: control group (Ctrl) or sham, varicocoele group (Vcl) which received no treatment, varicocoele group that was daily fed with hesperidin (Vcl+Hsp) at a dose of 50 mg/kg for eight weeks, and hesperidin group (Hsp) which received only hesperidin. At the end of the treatment period, the levels of oxidative stress markers were measured in plasma, and the expression of Bax and Bcl-2 was determined by immunocytochemistry and RT-qPCR methods. The index of apoptosis was assessed by the TUNEL assay. RESULTS Johnsen's score, the epithelium thickness, and diameter of seminiferous tubules were improved in the Vcl+Hsp group as compared to the Vcl group. Treatment with hesperidin enhanced the serum levels of glutathione peroxidase (GPx) and superoxide dismutase (SOD) enzymes and decreased the heightened concentrations of malondialdehyde (MDA) in testicular tissue (p < 0.001). Moreover, our results demonstrated that hesperidin considerably diminished Bax and increased Bcl-2 expression (gene and protein) levels compared with the Vcl group (p < 0.05). It also markedly reduced the rate of programmed cell death in germ cells (p < 0.05). CONCLUSIONS It seems that the treatment with hesperidin could mitigate testicular tissue damage in rats underwent varicocoele possibly through its antioxidant properties.

Abstract
BACKGROUND The existing classifications of varicocoeles have poor predictive value regarding the effects of surgery on sperm count. OBJECTIVE To develop a new grading system for varicocoeles, useful as an indication for surgery. MATERIALS AND METHODS This is a three-center prospective study which examined 173 men having clinically detectable left varicocoeles and oligo ± astheno ± terato-spermia. The patients underwent medical history collection, objective examination, duplex Doppler ultrasound scrotal examination, hormonal profiles, two semen analyses before surgery, and two semen analyses after surgery. Sperm concentration, motility, and morphology (standard semen parameters) were evaluated 6 months after surgery in function of the following preoperative variables: patient age, follicle-stimulating hormone, clinical grade of varicocoele, right and left testicular volume, extension of venous reflux, and semen parameters. The venous reflux was graded in two centers using duplex Doppler ultrasound: reflux visible only with Valsalva and continuous reflux. Spearman's rank semiquantitative analysis was used. All patients had their varicocoeles corrected according to the Colpi technique. RESULTS The variables capable of determining an improvement in semen parameters after varicocoele correction were in order of decreasing importance: venous reflux extent assessed by scrotal duplex Doppler ultrasound examination, varicocoele clinical grade, basal semen parameters, and follicle-stimulating hormone. Male age did not influence postoperative semen quality. Only patients with continuous reflux had their standard semen parameters improved after surgery. DISCUSSION Venous reflux extent is the most critical variable capable of predicting semen improvement after varicocoelectomy. CONCLUSIONS A correct duplex Doppler assessment of venous reflux is mandatory for predicting postoperative improvement of the sperm count.

Abstract
In a case-controlled study, we assessed the expressed seminal NAD-dependent protein deacetylase (SIRT1) expression in infertile oligoasthenoteratozoospermic (OAT) men associated with varicocoele. Our study involved 81 men, recruited from the University hospitals, after ethical approval and informed consent. They were allocated into fertile normozoospermic men (n = 23), infertile OAT men without varicocoele (n = 23) and infertile OAT men with varicocoele (n = 35). Inclusion criteria consisted of confirmation of abnormal semen parameters and normal female partners whereas exclusion criteria were leukocytospermia, tobacco smoking, hormonal therapy, immunological disorders, dyslipidemia, hypogonadism, cardiovascular disorders, morbid obesity, and hepatic or renal failures. All participants had an interview to assess clinical history, clinical examination, semen analysis, and estimation of seminal SIRT1 expression. Seminal SIRT1 expression was significantly lower in infertile OAT men than fertile men. Among infertile OAT men, seminal SIRT1 expression was significantly lower in those with varicocoele than in those without. Additionally, seminal SIRT1 expression was significantly lower in varicocoele grade III cases compared with other grades. Seminal SIRT1 expression was positively correlated with sperm concentration (r = 0.327, p = 0.001), total sperm motility (r = 0.532, p = 0.001), and sperm normal forms (r = 0.469, p = 0.001). Our results suggest that seminal SIRT1 expression has a role of male infertility being significantly decreased in infertile OAT men in general and in infertile OAT men associated with varicocoele in particular.

Abstract
The literature on the treatment of painful varicocoele is limited, likely because of the short period since it was recognized as a clinical entity and the limitations posed by the subjectivity of pain. Our aim was to systematically analyse the results of percutaneous embolization as the chosen treatment for this condition. We conducted a retrospective study of patients undergoing percutaneous embolization as primary treatment for painful varicocoele from January 2007 to November 2013. Radiologic and ultrasonographic successes were evaluated according to the existence or absence of venous reflux on venography after embolization and on Echo Doppler control at 3-6 months. Clinical success was assessed by Visual Analog Scale pain questionnaires before surgery and at 3-6 months; in addition, at the time of the study, telephone interviews were conducted to update the clinical situation and development. A total of 154 patients received operations. The median pain before surgery, at 3-6 months and at the time of interview was 7, 1 and 0 points respectively (p < 0.001). The ultrasonographic success rate at 3-6 months was 68.6%. With a median follow-up of 39 months, the success and relapse/clinical persistence rates were 86.9 and 13.1% respectively. By studying the degree of agreement between clinical success and ultrasonographic success, a kappa index = 0.443 was obtained. Patients with success recounted greater pre-operative pain scores than those who relapsed or persisted (7.5 vs. 5.0; p = 0.004). In patients with painful varicocoele, the ultrasonographic recurrence of venous reflux does not imply the recurrence of pain; hence, the proper assessment of success in these patients should include a systematic assessment of their pain and grade of reflux. Percutaneous retrograde embolization as a primary treatment for painful varicocoele is a clinically effective option with a high success rate that can be maintained in the long term, especially in patients with high pre-operative pain.

Abstract
We reviewed a large number of patients from 2000 to 2010 that underwent varicocoele correction using the retrograde sclerotization approach. Three hundred and seventy-six of them were included in the study, as they met the inclusion criteria. Mean age at the time of surgery was 32 years (SD: 6.5); 32% of them were 35 years and older. Patients were classified according to the clinical classification (GC) and Sarteschi's Doppler ultrasound classification (GS). The patients showed up at the clinic after an average time of 30 months of referred infertility related (SD: 28.54). Patients underwent pre-operative assessment with physical examination, sperm analysis and Doppler ultrasound, and again the same assessment at least 3 months after surgery. We evaluated the following parameters: sperm concentration (millions/mL, CONC), percentage motility (a+b, MOT) and the percentage of morphologically typical spermatozoa (MOR). Univariate and Multivariate analysis were performed. The research of Pearson's coefficients was performed to test the correlation between sperm parameters and age, SG, CG. Semen specimens were evaluated according to WHO 1999 criteria. Mean CONC varied from 34.5 to 47.0 millions/mL (+12.5; p < 0.001); MOT from 27.2 to 34.5% (+7.3%; p < 0.001); and MOR from 44.0 to 47.6% (+3.6%; p = 0.001). Univariable and multivariable analysis of variance related to age showed no significant difference of parameters improvement. Pearson's correlation coefficient for pre-operative and post-operative sperm MOT related to patients' age was respectively -0.11 (p < 0.001) and -0.18 (p = 0.04). No other significance was found. Usefulness of treating infertile patients affected by varicocoele is confirmed: varicocoele correction leads to significant sperm parameters improvement. There is no evidence of different improvement related to patients' age. The decline in sperm motility related to age of the patients seems to be only age-dependent: the usefulness of treating patients affected by varicocoele is not influenced by their age: treatment should also be offered to older patients.

Abstract
The role of antisperm antibodies (ASA) in the aetiopathogenesis of varicocoele-related male infertility remains unclear. The objective of this study was to determine whether varicocoele is associated with antisperm immune response and whether this factor provides additional affect on male fertility. We performed a multicentral, prospective study that included the clinical examination of 1639 male subjects from infertile couples and 90 fertile men, the evaluation of the absolute and relative risks of immune infertility associated with varicocoele and the impact of the autoimmune response on the semen quality. The methods used were as follows: standard examination of seminal fluid according to WHO criteria; ASA detection in seminal fluid using mixed antiglobulin reaction (MAR) and direct flow cytometry; measurement of spontaneous and ionophore-induced acrosome reactions; oxidative stress evaluation with luminal-dependent chemiluminescence method and evaluation of DNA fragmentation by sperm chromatin dispersion. The prevalence of varicocoele-related immune infertility is about 15% and does not depend on the grade of vein dilatation both in primary and secondary fertility disorders. Varicocoele is not an immediate cause of autoimmune reactions against spermatozoa, but is a cofactor increasing ASA risk; the OR of immune infertility after a testicular trauma in varicocoele patients increases twofold. In varicocoele patients, the autoimmune antisperm reaction is accompanied by a more significant decrease in the semen quality (concentration and number of progressively motile and morphologically normal spermatozoa in the ejaculate), acrosome reaction disorders (presence of pre-term spontaneous and lack of induced reactions) and an increase in the proportion of spermatozoa with DNA fragmentation. These disorders correlate with the level of sperm oxidative stress; reactive oxygen species (ROS) production in ASA-positive varicocoele patients is 2.8 and 3.5 times higher than in ASA-negative varicocoele patients and fertile men respectively. We did not find correlation between the grade of spermatic cord vein dilatation and ROS production.

Abstract
Varicocoele is an important cause of male infertility. Normal male reproductive function and fertility depends on a delicate balance between androgen receptor (AR) and the classic oestrogen receptors ESR1 (ERα) and ESR2 (ERβ). Using a model of surgically induced varicocoele in rats, this study aimed to investigate the effects of varicocoele on the expression of AR, ESR1, ESR2 and G-protein coupled oestrogen receptor (GPER). Varicocoele did not affect the mRNA and protein expression of ESR1 and ESR2 in both testes. Varicocoele did not affect the mRNA and protein expression of GPER in the right testis, but slightly reduced the mRNA and increased the protein levels in the left testis. Varicocoele did not affect the mRNA for AR, but reduced the protein levels in both testes. A proteomic approach was used in an attempt to find differentially expressed targets with possible correlation with AR downregulation. Varicocoele caused the differential expression of 29 proteins. Six proteins were upregulated, including the receptor for activated C kinase 1 (RACK1), and 23 were downregulated, including dihydrolipoamide dehydrogenase, alpha-enolase and pyrophosphatase 1. Western blot analysis confirmed that varicocoele upregulated the expression of RACK1, a protein involved with tyrosine phosphorylation and regulation of AR transcriptional activity, AR metabolism and dynamics of the blood-testis barrier. In conclusion, this study suggests that varicocoele affects mechanisms that control AR expression and function. This regulation of AR may play an important role in the varicocoele-induced testicular dysfunction. Furthermore, varicocoele downregulates several other proteins in the testis that may be useful markers of spermatozoa function and male infertility.
