Evaluation of telomere length, reactive oxygen species, and apoptosis in spermatozoa of patients with oligospermia. Cell Biochem Funct 2024; 42:e3935.

Abstract
50% of cases of infertility are caused by male factor, which acquired or congenital problems may bring on. Male infertility can be caused by oligospermia and asthenozoospermia, which are common. Since the same mutations that cause azoospermia in some people also cause oligozoospermia in others, oligozoospermia may be thought of as a less severe form of azoospermia. Studies have demonstrated telomere length, catalase activity, super oxide dismutase (SOD), and DNA fragmentation can be influential factors for male infertility. The amount of apoptosis, oxidative stress factors, telomere length, and DNA fragmentation were some aspects of healthy sperm that we chose to look into in this study and compare to oligospermia individuals. Oligospermia patients (n = 24) and fertile men (n = 27) semen samples were collected, and the apoptosis rate of sperms in both groups was analyzed (Flow cytometry). Also, gene expression of apoptotic and antiapoptotic markers and telomere length were examined (real-time polymerase chain reaction). The sperm DNA fragmentation kit was used to determine DNA fragmentation and to evaluate catalase and SOD activity; the specific kits and methods were utilized. Higher expression levels of caspase3 (p = .0042), caspase8 (p = .0145), caspase9 (p = .0275), and BAX (p = .0202) mRNA were observed in patients who had oligospermia. In contrast, lower mRNA expression of BCL-2 (p = .0009) was detected in this group. In addition, telomere length was decreased in the oligospermia group (p < .0001) compared to the health group. Moreover, the frequency of apoptosis is induced in patients (p = .0026). The catalase activity is low (p = .0008), but the SOD activity is high (p = .0015) in the patient group. As a result of our findings, we may list the sperm cell apoptosis rate, telomere length, the degree of sperm DNA fragmentation, and lastly, the measurement of significant and efficient oxidative stress markers like SOD and catalase in semen plasma among the principal diagnostic characteristics for oligospermia. Future studies will be better able to treat oligospermia by showing whether these indicators are rising or falling.

Abstract
PURPOSE OF REVIEW This review summarizes the pathway of Mullerian and Wolffian duct development, anomalies that result from disruptions to this pathway, and the characteristics on advanced imaging that identify them. RECENT FINDINGS In-office evaluation for reproductive anomalies is usually inadequate for the diagnosis of congenital reproductive anomalies. Magnetic resonance imaging (MRI) has usurped invasive diagnostic methods including laparoscopy, hysteroscopy, and vasography as the new gold standard. Because of its superior soft-tissue delineation and the availability of advanced functional sequences, MRI offers a sophisticated method of distinguishing reproductive anomalies from one another, characterizing the degree of defect severity, and evaluating for concomitant urogenital anomalies non-invasively and without radiation exposure to the patient. Congenital anomalies of the Mullerian and Wolffian duct can be incredibly nuanced, requiring prompt and accurate diagnosis for management of infertility. Definitive diagnosis should be made early with MRI.

Abstract
PURPOSE One of the most important complications of undescended testis (UDT) surgery is testicular atrophy (TA). We aimed to investigate the factors associated with TA in children who underwent orchiopexy for unilateral UDT. METHODS The data of 215 patients aged < 15 years who underwent orchiopexy for unilateral UDT between November 2019 and September 2022 were analyzed retrospectively. Clinical, radiological, surgical, and follow-up findings were recorded. RESULTS TA was observed in 29 (13.5%) patients. Mean resistive index (RI) values were 0.44 ± 0.06, 0.54 ± 0.09 and 0.69 ± 0.1 in low, middle and high testicular locations, respectively, and intratesticular RI increased significantly as the testis location raised (p < 0.001). After orchiopexy, the mean testis volume ratio (TVR) increased significantly (0.63 ± 0.13 vs. 0.77 ± 0.15, p < 0.001). Besides, the mean RI values decreased significantly in the postoperative follow-up (0.53 ± 0.12 vs. 0.47 ± 0.13, p < 0.001). In multivariate regression analysis, testicular high location (OR 4.332, 95% CI 2.244-6.578, p = 0.002), deferens-epididymal anomaly (OR 3.134, 95% CI 1.345-7.146, p = 0.021), TVR ≤ 0.5 (OR 5.679, 95% CI 2.953-12.892, p < 0.001) and RI ≥ 0.6 (OR 7.158, 95% CI 3.936-14.569, p < 0.001) were independent predictive factors for TA after orchiopexy. CONCLUSION Higher testis location, deferens-epididymis anomaly, preoperative TVR and RI were independent predictive factors for TA after orchiopexy in unilateral UDT. The results of the study will help surgeons to predict TA before orchiopexy.

Impact of Escherichia coli Outer Membrane Vesicles on Sperm Function. Pathogens 2022; 11:pathogens11070782.

Abstract
Reproductive tract infections account for approximately 15% of male infertility cases. Escherichia coli (E. coli) represents the most frequently isolated bacterial strain in the semen of infertile men. All Gram-negative bacteria constitutively produce outer membrane vesicles (OMVs). The present study proved, for the first time, the involvement of OMVs in human sperm function. E. coli OMVs were isolated by ultracentrifugation and characterized via sodium dodecyl sulfate–polyacrylamide gel electrophoresis (SDS-PAGE), transmission electron microscopy (TEM) and dynamic light scattering (DLS) analysis. Human sperm was exposed to OMVs (8 µg/mL) for different times (30, 45, 60 and 90 min). The vitality, motility, morphology, ROS level and DNA fragmentation of spermatozoa were evaluated. OMVs reduced the progressive motility and increased the immobile spermatozoa amount after 30 min of treatment. In addition, a significant increase in the percentage of intracellular ROS and sperm DNA fragmentation was recorded for each vesicular exposure time. These preliminary findings prove that OMVs contribute to altering human sperm function via two mechanisms: (i) impaired motility and (ii) DNA fragmentation.

Abstract
Cystinosis is an inherited metabolic disorder caused by autosomal recessive mutations in the CTNS gene leading to lysosomal cystine accumulation. The disease primarily affects the kidneys followed by extra-renal organ involvement later in life. Azoospermia is one of the unclarified complications which are not improved by cysteamine, which is the only available disease-modifying treatment. We aimed at unraveling the origin of azoospermia in cysteamine-treated cystinosis by confirming or excluding an obstructive factor, and investigating the effect of cysteamine on fertility in the Ctns-/- mouse model compared with wild type. Azoospermia was present in the vast majority of infantile type cystinosis patients. While spermatogenesis was intact, an enlarged caput epididymis and reduced levels of seminal markers for obstruction neutral α-glucosidase (NAG) and extracellular matrix protein 1 (ECM1) pointed towards an epididymal obstruction. Histopathological examination in human and mouse testis revealed a disturbed blood-testis barrier characterized by an altered zonula occludens-1 (ZO-1) protein expression. Animal studies ruled out a negative effect of cysteamine on fertility, but showed that cystine accumulation in the testis is irresponsive to regular cysteamine treatment. We conclude that the azoospermia in infantile cystinosis is due to an obstruction related to epididymal dysfunction, irrespective of the severity of an evolving primary hypogonadism. Regular cysteamine treatment does not affect fertility but has subtherapeutic effects on cystine accumulation in testis.

Diagnostic accuracy of resistive index of capsular and intratesticular branches of testicular arteries in infertile men with oligoasthenospermia: A case-control study. Biomedicine (Taipei) 2021; 10:18-22. [PMID: 33854930 PMCID: PMC7735981 DOI: 10.37796/2211-8039.1036] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/18/2020] [Accepted: 04/27/2020] [Indexed: 11/01/2022] Open
Abstract
Introduction Male infertility accounts for nearly 50% of couples' infertility. Only a few studies evaluate the diagnostic accuracy of resistive index (RI) of testicular arteries using color Doppler imaging to identify male infertility. The aim of this study was to investigate the diagnostic accuracy of RI of the capsular and intratesticular branches of testicular arteries in infertile men with oligoasthenospermia and its comparison with normal men. Material and methods In a case-control study, 30 patients with oligoasthenospermia (case group) and 30 healthy controls who meet the inclusion criteria, were selected. For all patients, RI was measured using color Doppler ultrasonography in upper and lower testicular poles. Also, testicular volumes were measured for all participants. Results Mean RI of the intratesticular artery (0.624 ± 0.051 versus 0.509 ± 0.054; P < 0.001) and capsular artery (0.663 ± 0.057 versus 0.557 ± 0.055; P < 0.001) were significantly higher in the case group compared to control group. The frequency of abnormal RI of intratesticular artery in the control (13.3%) and case (66.7%) groups were significantly different (OR: 13.0; 95% CI: 3.44-47.59; P < 0.001). The sensitivity, specificity, positive predictive value (PPV), negative predictive value (NPV) and overall accuracy (OA) of intratesticular artery RI were 66.67%, 86.67%, 83.33%, 72.22%, and 76.67%, respectively. The frequency of abnormal RI of capsular artery was 23.3% in the control group and 90.0% in the case group (OR: 29.57; 95% CI: 6.85-127.63; P < 0.001). The sensitivity, specificity, PPV, NPV and OA of capsular artery RI were 90.0%, 76.67%, 79.41%, 88.46% and 83.33%, respectively. Conclusion The results of this study indicated that assessing testicular Doppler RI of capsular and intratesticular branches of the testicular arteries, as a bio-imaging biomarker, may be a valuable non-invasive and simple complementary diagnostic modality with a high diagnostic value in identifying infertile men with oligoasthenospermia.

Obstructive oligospermia: the role of interventional radiology in its diagnosis and treatment. Pol J Radiol 2021; 86:e204-e207.

Abstract
Purpose According to the latest World Health Organization guidelines (2010), oligo-sperm it is due to a sperm concentration of less than 15 million/ml of seminal fluid. The cause can be obstructive and non-obstructive. Interventional radiology allows diagnosis and, in some cases, minimally invasive treatment. Case presentation A 28-year-old man with oligospermia (7 million/ml of seminal fluid), surgically treated 2 years ago for clinical grade III bilateral varicocele (according to Dubin’s classification), was admitted to the Urology Department for suspected accidental surgical ligation of the left vas deferens. The patient underwent several diagnostic tests including phlebography of the left pampiniform plexus, bilateral vesico-deferentography. The steno-occlusion of the ejaculatory ducts was diagnosed, which was resolved through an innovative interventional radiology treatment. Conclusions Interventional radiology has played a decisive role in the diagnosis and treatment of the causes of male infertility. In our experience, it has considerable potential in the minimally invasive treatment of steno-obstructive pathologies of the vesico-deferential system.
