Abstract
BACKGROUND The escalating prevalence of fertility problems in the aging population necessitates a comprehensive exploration of contributing factors, extending beyond environmental concerns, work-related stress, and unhealthy lifestyles. Among these, the rising incidence of testicular disorders emerges as a pivotal determinant of fertility issues. Current treatment challenges are underscored by the limitations of high-dose and frequent drug administration, coupled with substantial side effects and irreversible trauma inflicted by surgical interventions on testicular tissue. MATERIAL AND METHODS The formidable barrier posed by the blood-testis barrier compounds the complexities of treating testicular diseases, presenting a significant therapeutic obstacle. The advent of nanocarriers, with their distinctive attributes, holds promise in overcoming this impediment. These nanocarriers exhibit exceptional biocompatibility, and membrane penetration capabilities, and can strategically target the blood-testis barrier through surface ligand modification, thereby augmenting drug bioavailability and enhancing therapeutic efficacy. RESULTS AND DISCUSSION This review concentrates on the transformative potential of nanocarriers in the delivery of therapeutic agents to testicular tissue. By summarizing key applications, we illuminate the strides made in utilizing nanocarriers as a novel avenue to effectively treat testicular diseases. CONCLUSIONS Nanocarriers are critical in delivering therapeutic agents to testicular tissue.

Abstract
PURPOSE To investigate cryopreserved testicular spermatozoa among patients with azoospermia. METHODS In this retrospective study spanning from October 1993 to December 2021, we examined men diagnosed with azoospermia who underwent testicular spermatozoa cryopreservation. Data from medical records included utilization and disposal of sperm samples, age at initial cryopreservation. We analyzed the data over 20 years using Kaplan-Meier curves, compared age with the log-rank test, and assessed hazard ratios (HR) with 95% confidence intervals (CI) using Cox regression analysis. RESULTS A total of 356 patients with a mean age of 32.1 ± 6 were included. Of these, 225 patients utilized thawed testicular sperm for fertility treatments, with 118 patients using all their frozen straws and 107 patients partially using their stored straws. Additionally, 29 patients opted for disposal (six patients partially used their testicular spermatozoa before disposal), resulting in 108 patients who neither used nor disposed of their straws. From a laboratory standpoint, nearly 90% of patients contributed a single testicular sample, which was subsequently divided and cryopreserved as straws, with a median of 4 straws per sample. Notably, in the older age group (> 35 years old), there were a significantly lower usage rate and a higher disposal rate compared to the younger age groups (p < 0.05 for both), corroborated by univariable Cox analysis. CONCLUSIONS This extensive study unveils unique patterns in the preservation and disposal of testicular spermatozoa among azoospermic patients. Most patients utilize a significant portion of their stored samples, while older patients tend to use their testicular spermatozoa less frequently.

Abstract
Spinal muscular atrophy (SMA) is a neuromuscular disease caused by deletions or mutations in the survival of motor neuron 1 (SMN1) gene resulting in reduced levels of SMN protein. SMN protein is produced by cells throughout the body, and evidence suggests that low SMN protein can have systemic implications, including in male reproductive organs. However, a paucity of research exists on this important topic. This article will discuss findings from non-clinical studies on the role of SMN in the male reproductive system; additionally, real-world observational reports of individuals with SMA will be examined. Furthermore, we will review the non-clinical reproductive findings of risdiplam, a small-molecule SMN2 splicing modifier approved for the treatment of SMA, which has widespread distribution in both the central nervous system and peripheral organs. Specifically, the available non-clinical evidence of the effect of risdiplam on male reproductive organs and spermatogenesis is examined. Lastly, the article will highlight available capabilities to assess male fertility as well as the advanced reproductive technologies utilized to treat male infertility. This article demonstrates the need for further research to better understand the impacts of SMA on male fertility and reproduction.

Abstract
OBJECTIVE To reveal the overall sperm retrieval rate (SRR) and range in patients with azoospermia factor c (AZFc) microdeletion azoospermia by microdissection testicular sperm extraction (mTESE) and discuss the differences of preoperative patient factors among studies with various SRRs. PATIENTS AND METHODS We searched PubMed, Web of Science and Embase until February 2023. All studies reporting SRRs by mTESE and required parameters of patients with AZFc microdeletions were included. The primary outcome was the SRR and, if available, the pregnancy rate (PR) and live-birth rate (LBR) after intracytoplasmic sperm injection were also investigated as secondary outcomes. RESULTS Eventually 11 cohort studies were included in this review. A total number of 441 patients underwent mTESE and in 275 of them sperm was obtained, reaching an overall SRR of 62.4%. The SRRs among studies had a wide range from 25.0% to 85.7%. The studies reporting higher SRRs generally had older mean ages, and higher follicle-stimulating hormone and testosterone levels. Only four studies provided practical data on pregnancies and live-born children of patients with AZFc microdeletions, so the overall PR and LBR were unavailable. CONCLUSIONS The overall SRR of patients with AZFc microdeletion azoospermia was 62.4%. The effect of patient factors in SR needs further evidence in future work.

Abstract
We investigated the prognostic importance of noninvasive factors in predicting sperm retrieval failure in idiopathic nonobstructive azoospermia (iNOA). We studied 193 patients with nonobstructive azoospermia who underwent microsurgical testicular sperm extraction. The Chi-square test and Mann-Whitney U tests for clinical parameters and seminiferous tubule distribution were used for between-group comparisons. A logistic regression analysis was conducted to identify predictors of retrieval failure. Area under the receiver operating characteristic curve for each variable was evaluated, and the net clinical benefit was calculated using a clinical decision curve. Patients with iNOA had a lower sperm retrieval rate than those with known causes. Moreover, testicular volume was an independent factor affecting sperm extraction outcomes (odds ratio = 0.79, P < 0.05). The testicular volume cut-off value was 6.5 ml (area under the curve: 0.694). The patients with iNOA were categorized into two groups on the basis of the distribution of seminiferous tubules observed. The sperm retrieval rate and testicular volume were significantly different between the groups with a uniform or heterogeneous tubule distribution. There was also a significant association between a uniform tubule distribution and testicular volume. In conclusion, a testicular volume of more than 6.5 ml effectively predicts microsurgical testicular sperm extraction failure due to a uniform tubule distribution in patients with iNOA.

Pentoxifylline treatment as a safe method for selecting viable testicular spermatozoa before cryopreservation of a small numbers of spermatozoa in azoospermia individuals. Arch Ital Urol Androl 2024; 96:12525. [PMID: 38934523 DOI: 10.4081/aiua.2024.12525] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/29/2024] [Accepted: 04/13/2024] [Indexed: 06/28/2024] Open
Abstract
BACKGROUND Single sperm cryopreservation (SSC) is a specific technique especially used in individuals with small numbers of sperm who suffered from non-obstructive azoospermia (NOA). Testicular specimens possess poor motility and low population of viable spermatozoa. Therefore, sperm selection methods such as applying pentoxifylline (PTX) may improve motility in these cases. The main aim of this study was to evaluate the protective effects of PTX on testicular spermatozoa before and after performing SSC. METHODS Thirty testicular samples were obtained from men with azoospermia. This study was conducted in two phases. Phase 1 evaluated the effect of PTX for sperm selection before SSC. Twenty testicular samples were divided to two experimental groups: SSC without (I) and with PTX treatment (II). For PTX treatment spermatozoa were incubated with PTX at 37°C for 30 min and only motile spermatozoa were selected for SSC. In phase 2, ten testicular samples were cryopreserved with SSC and warming procedure was carried out in droplet with and without PTX. Motility and viability rates, morphology by motile sperm organelle morphology examination (MSOME), DNA fragmentation by sperm chromatin dispersion test (SCD) and mitochondrial membrane potential (MMP) were evaluated. RESULTS In phase 1, post warm motility rate was higher in PTX exposed group compared to the unexposed group (25.6 ± 8.13 vs. 0.85 ± 2.1) (p > 0.00). Recovery rate, viability and morphology were not significantly different between groups. DNA integrity and MMP were also similar between both groups. In phase 2 although motility increased in PTX group compared to without PTX group (29.30 ± 12.73 vs. 1.90 ± 2.64) (p > 0.00), the viability rate was not different (70.40 ± 12.12 vs. 65.30 ± 11.87). All above mentioned parameters were similar between the two SSC groups. CONCLUSIONS Supplementation of testicular spermatozoa with PTX before cryopreservation increases motility and did not have adverse effects on viability, morphology, DNA integrity and MMP. PTX could be used as sperm selection method before single sperm cryopreservation, but PTX could not maintain motile the most of viable testicular sperms.

Clinical factors impacting microdissection testicular sperm extraction success in hypogonadal men with nonobstructive azoospermia. Fertil Steril 2024:S0015-0282(24)00544-2. [PMID: 38909671 DOI: 10.1016/j.fertnstert.2024.06.013] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/22/2024] [Revised: 06/09/2024] [Accepted: 06/17/2024] [Indexed: 06/25/2024]
Abstract
OBJECTIVE To explore factors influencing microdissection testicular sperm extraction (micro-TESE) success in hypogonadal men with nonobstructive azoospermia (NOA). DESIGN A cohort study. SETTING University-affiliated male reproductive health center. PATIENT(S) A total of 616 consecutive patients with NOA and hypogonadism (total testosterone [T] levels <350 ng/dL) underwent micro-TESE between 2014 and 2021. All patients had no prior sperm retrieval (SR) history. INTERVENTION(S) Patients aged 23-55 years underwent comprehensive clinical, laboratory, and histopathological diagnostic evaluation for NOA and were further categorized into two cohorts on the basis of pre-SR hormonal stimulation. MAIN OUTCOME MEASURE(S) A multivariable logistic regression analysis explored the associations between patient variables and micro-TESE success, defined as the presence of viable spermatozoa in extracted specimens. Adjusted odds ratios (aORs) and 95% confidence intervals (CIs) were computed to assess the relationship between SR success and relevant predictors. Sperm retrieval rates were compared between patients receiving or not hormonal stimulation, and logistic regression analysis evaluated the effect of baseline follicle-stimulating hormone levels (i.e., normogonadotropic vs. hypergonadotropic classes) on SR success. RESULT(S) The overall micro-TESE success rate was 56.6%. Baseline follicle-stimulating hormone levels (aOR, 0.97; 95% CI, 0.94-0.99), pre-SR hormonal stimulation (aOR, 2.54; 95% CI, 1.64-3.93), presence of clinical varicocele (aOR, 0.05; 95% CI, 0.01-0.51), history of previous varicocelectomy (aOR, 2.55; 95% CI, 1.26-5.16), and testicular histopathology were independent predictors of SR success. Among hormone-pretreated patients, pre-micro-TESE T levels and delta T (an absolute increase in T levels from baseline) were associated with SR success. A pre-micro-TESE T level of 418.5 ng/dL (area under the curve value: 0.78) and a delta T of 258 ng/dL (area under the value: 0.76) distinguished patients with positive and negative SR outcomes. Subgroup analysis showed that pre-SR hormonal stimulation yielded a greater benefit for normogonadotropic patients than for those who were hypergonadotropic. CONCLUSION(S) This study underscores the association between clinical factors and micro-TESE success in hypogonadal men with NOA. Although causality is not established, our findings suggest that these patients may benefit from pre-SR interventions, particularly hormonal stimulation and varicocele repair. CLINICAL TRIAL REGISTRATION NUMBER NCT05110391.

Abstract
ABSTRACT Discovery of spermatozoa during the 17th century led to developing technologies for semen analysis in the early 1900s, and then, standard techniques were implemented during the 20th century. Semen analysis has a pivotal role in the male infertility evaluation, and azoospermia is an important finding. Azoospermia is identified in 15% of infertile men. However, the accurate laboratory assessment of azoospermia poses certain technical challenges. Laboratories currently perform semen assessment with great variability; thus, a standard method should be used. Planning suitable management and determining the cause of infertility require a precise evaluation of azoospermia. This review aims to address the definition of azoospermia and highlight laboratory methods in the assessments of azoospermia. Basic methods such as centrifugation, repeat pellet analysis, and staining and advanced methods such as genetic testing and biomarkers have been discussed. These methods have helped in standardizing the protocol for accurate azoospermia assessments with less variability.

Abstract
Introduction Azoospermia, characterized by an absence of sperm in the ejaculate, represents the most severe form of male infertility. While surgical sperm retrieval in obstructive azoospermia (OA) is successful in the majority of cases, patients with non-obstructive azoospermia (NOA) show retrieval rates of only about 50% and thus frequently have unnecessary surgery. Surgical intervention could be avoided if patients without preserved spermatogenesis are identified preoperatively. This prospective study aimed to discover biomarkers in seminal plasma that could be employed for a non-invasive differential diagnosis of OA/NOA in order to rationalize surgery recommendations and improve success rates. Methods All patients signed written informed consent, underwent comprehensive andrological evaluation, received human genetics to exclude relevant pathologies, and patients with azoospermia underwent surgical sperm retrieval. Using label-free LC-MS/MS, we compared the proteomes of seminal plasma samples from fertile men (healthy controls (HC), n=8) and infertile men diagnosed with 1) OA (n=7), 2) NOA with successful sperm retrieval (mixed testicular atrophy (MTA), n=8), and 3) NOA without sperm retrieval (Sertoli cell-only phenotype (SCO), n=7). Relative abundance changes of two candidate markers of sperm retrieval, HSPA2 and LDHC, were confirmed by Western Blot. Results We found the protein expression levels of 42 proteins to be significantly down-regulated (p ≤ 0.05) in seminal plasma from SCO NOA patients relative to HC whereas only one protein was down-regulated in seminal plasma from MTA patients. Analysis of tissue and cell expression suggested that the testis-specific proteins LDHC, PGK2, DPEP3, and germ-cell enriched heat-shock proteins HSPA2 and HSPA4L are promising biomarkers of spermatogenic function. Western blotting revealed a significantly lower abundance of LDHC and HSPA2 in the seminal plasma of men with NOA (SCO and MTA) compared to controls. Discussion The results indicate that certain testis-specific proteins when measured in seminal plasma, could serve as indicators of the presence of sperm in the testis and predict the success of sperm retrieval. Used in conjunction with conventional clinical assessments, these proteomic biomarkers may assist in the non-invasive diagnosis of idiopathic male infertility.

Abstract
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.

APHRODITE criteria: addressing male patients with hypogonadism and/or infertility owing to altered idiopathic testicular function. Reprod Biomed Online 2024; 48:103647. [PMID: 38367592 DOI: 10.1016/j.rbmo.2023.103647] [Citation(s) in RCA: 3] [Impact Index Per Article: 3.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/23/2023] [Revised: 10/25/2023] [Accepted: 10/26/2023] [Indexed: 02/19/2024]
Abstract
RESEARCH QUESTION Can a novel classification system of the infertile male - 'APHRODITE' (Addressing male Patients with Hypogonadism and/or infeRtility Owing to altereD, Idiopathic TEsticular function) - stratify different subgroups of male infertility to help scientists to design clinical trials on the hormonal treatment of male infertility, and clinicians to counsel and treat the endocrinological imbalances in men and, ultimately, increase the chances of natural and assisted conception? DESIGN A collaboration between andrologists, reproductive urologists and gynaecologists, with specialization in reproductive medicine and expertise in male infertility, led to the development of the APHRODITE criteria through an iterative consensus process based on clinical patient descriptions and the results of routine laboratory tests, including semen analysis and hormonal testing. RESULTS Five patient groups were delineated according to the APHRODITE criteria; (1) Hypogonadotrophic hypogonadism (acquired and congenital); (2) Idiopathic male infertility with lowered semen analysis parameters, normal serum FSH and normal serum total testosterone concentrations; (3) A hypogonadal state with lowered semen analysis parameters, normal FSH and reduced total testosterone concentrations; (4) Lowered semen analysis parameters, elevated FSH concentrations and reduced or normal total testosterone concentrations; and (5) Unexplained male infertility in the context of unexplained couple infertility. CONCLUSION The APHRODITE criteria offer a novel and standardized patient stratification system for male infertility independent of aetiology and/or altered spermatogenesis, facilitating communication among clinicians, researchers and patients to improve reproductive outcomes following hormonal therapy. APHRODITE is proposed as a basis for future trials of the hormonal treatment of male infertility.

Achermann AP, Esteves SC. Prevalence and clinical implications of biochemical hypogonadism in patients with nonobstructive azoospermia undergoing infertility evaluation. F S Rep 2024; 5:14-22. [PMID: 38524219 PMCID: PMC10958705 DOI: 10.1016/j.xfre.2023.11.007] [Citation(s) in RCA: 1] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/26/2023] [Accepted: 11/12/2023] [Indexed: 03/26/2024] Open
Abstract
Objective To investigate the prevalence and clinical implications of biochemical hypogonadism in infertile men with nonobstructive azoospermia (NOA). Design Cohort study. Setting University-affiliated tertiary center for male reproductive health. Patients 767 consecutive normogonadotropic or hypergonadotropic patients with NOA undergoing infertility evaluation from 2014 to 2021. Intervention Patients aged 23-55 years underwent comprehensive clinical, hormonal, genetic, semen analysis, and histopathology evaluations and were classified on the basis of predefined baseline follicle-stimulating hormone (12 IU/L) and total testosterone (350 ng/dL) serum levels cutpoints into four groups: hypergonadotropic hypogonadal, hypergonadotropic eugonadal, normogonadotropic hypogonadal, and normogonadotropic eugonadal. All patients were naïve regarding previous sperm retrieval (SR) or hormonal therapy use. Main Outcome Measures The period prevalence of biochemical hypogonadism, defined as testosterone levels of <350 ng/dL, and the distribution of patients per group were computed. The associations between hypogonadism, clinical factors, and SR success were evaluated using multivariable logistic regression analyses. Adjusted relative risks (aRRs) and 95% confidence intervals (CIs) were estimated to assess the association between SR and patient classification. Results The overall period prevalence of biochemical hypogonadism was 80.8% (95% CI 77.9%-83.4%). The prevalence of patients by group was hypergonadotropic hypogonadal (42.4%, 38.9%-45.9%), normogonadotropic hypogonadal (38.5%; 35.1%-41.9%), hypergonadotropic eugonadal (8.3%; 6.6%-10.5%), and normogonadotropic eugonadal (10.8%; 8.8%-13.2%). Reduced testicular volume and lower estradiol levels were associated with an increased likelihood of hypogonadism. Paternal age was also an independent predictor, with higher age linked to an increased likelihood of hypogonadism. Hypogonadism was less likely in patients with germ cell maturation arrest and more likely in those with Sertoli cell-only. Patients with hypergonadotropic hypogonadism had lower SR success than normogonadotropic eugonadal counterparts (aRR 0.611; 95% CI 0.398-0.855). In the subset of hypogonadal men, hypergonadotropic patients had lower SR success than normogonadotropic participants (aRR 0.632; 0.469-0.811). Conclusion The prevalence of biochemical hypogonadism among men with NOA is substantial. Hypogonadism is associated with testicular volume, estradiol levels, age, and histopathology patterns. This condition impacts SR success and emphasizes the need for improved care for men with NOA.

Abstract
Mitochondrial function plays an important role in the maintenance of male fertility. However, the mechanisms underlying mitochondrial defect-related infertility remain mostly unclear. Here we show that a deficiency of PARL (Parl-/-), a mitochondrial protease, causes complete arrest of spermatogenesis during meiosis I. PARL deficiency led to severe downregulation of proteins of respiratory chain complex IV in testes that did not occur in other tested organs, causing a deficit in complex IV activity and ATP production. Furthermore, Parl-/- testes showed an almost complete loss of HSD17B3, a protein of the sER responsible for the last step in testosterone synthesis. While testosterone production appeared to be restored by overexpression of HSD17B12, loss of the canonical testosterone synthesis led to an upregulation of luteinizing hormone (LH) and of LH-regulated responses. These results suggest an important impact of the downstream regulation of mitochondrial defects that manifest in a cell-type-specific manner and extend beyond mitochondria.

The association between levels of samarium, hafnium, tungsten and rhenium in seminal plasma and the risk of idiopathic oligo-astheno-teratozoospermia in men of childbearing age. ENVIRONMENTAL SCIENCE AND POLLUTION RESEARCH INTERNATIONAL 2024; 31:668-681. [PMID: 38017218 DOI: 10.1007/s11356-023-31017-2] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 08/31/2023] [Accepted: 11/07/2023] [Indexed: 11/30/2023]
Abstract
Oligo-astheno-teratozoospermia (OAT) is a global public health problem, which affects 30% men of childbearing age. Meanwhile, with the rapid development of industry and economy, the contents of rare earth elements (REEs) in the environment are increasing. However, little is known about the associations between REEs levels and OAT risk. To evaluate the associations between the levels of four REEs (samarium (Sm), hafnium (Hf), tungsten (W), rhenium (Re)) in seminal plasma and OAT risk, from October 2021 to November 2022, semen samples from 924 men of childbearing age (460 controls and 464 cases) were collected from the reproductive center of the First Affiliated Hospital of Anhui Medical University. Inductively coupled plasma-mass spectrometry (ICP-MS) was used to measure the levels of Sm, Hf, Re and W in seminal plasma. Bayesian kernel machine regression (BKMR) was conducted to explore the joint effects of levels of four REEs in seminal plasma on the risk of OAT and select the one exerting a major role; generalized linear regression models (GLM) with log link function were employed to investigate the association of every REE level in seminal plasma and OAT risk; sankey diagram and linear regression models were utilized to describe the associations between the levels of four REEs and the indexes of sperm quality. The levels of four REEs in seminal plasma were higher in the case group than levels in the control group (pSm = 0.011, pHf = 0.040, pW = 0.062, pRe = 0.001, respectively). In BKMR analysis, the OAT risk increased when the overall levels of four REEs were higher than their 55th percentile compared to all of them at their 50th percentile, and Re level played a major role in the association. Additionally, Re level in seminal plasma was positively associated with the OAT risk in the single element model after adjustment of covariates (medium vs. low: OR (95% CI) = 1.55 (1.10, 2.18); high vs. low: OR (95% CI) = 1.69 (1.18, 2.42)). Lastly, the sankey diagram and linear regression models revealed that Sm level was negatively associated with the PR%, total sperm count and total progressively motile sperm count; Hf level was negatively associated with the PR%; W and Re levels were negatively associated with the PR% and total motility, and Re level was positively associated with abnormal morphology rate. Men of childbearing age with OAT had higher levels of Sm, Hf and Re in seminal plasma than those in the control group. An increasing trend for the OAT risk was observed with an increase in mixture levels of Sm, Hf, W and Re, and Re exposure level played a major role in the association whether in BKMR model or single element model. Additionally, the levels of these four REEs were negatively associated with the indexes of sperm quality.

Abstract
MiR-34b-5p has been reported as a non-invasive diagnostic biomarker for infertility. However, no gene targets regulating the mechanism of cation of this miRNA are known. In this study, using gene set enrichment analysis the Inositol 1,4,5-Trisphosphate Receptor Type 1 (ITPR1) gene was identified as the sole target for hsa-miR-34b-5p, and found significantly overexpressed in non-obstructive azoospermia (NOA) patients. This finding was confirmed by qRT-PCR on fresh testicular tissues from NOA patients. Then, pathway enrichment analysis as well as the diagnostic value analysis of hsa-miR-34b-5p/ITPR1 indicated ITPR1 as a hub gene in the calcium (Ca2+)-apoptosis pathway, and a valuable predictive biomarker for NOA. Moreover, gene expression and histological assays showed the association of the effects of ITPR1's increased expression on spermatogenesis failure through induction of apoptosis in NOA patients. These data suggested that the hsa-miR-34b-5p/ITPR1 axis could serve as a potential regulatory predictive biomarker for human spermatogenesis through the Ca2+-apoptosis pathway cross-talk.

Abstract
Background Azoospermia is the most severe type of male infertility. This study aimed to identify useful clinical parameters to predict sperm retrieval success. This could assist clinicians in accurately diagnosing and treating patients based on the individual clinical parameters of patients. Methods A retrospective cohort study was performed involving 517 patients with azoospermia who underwent sperm retrieval in Jakarta, Indonesia, between January 2010 and April 2023. Clinical evaluation and scrotal ultrasound, serum follicle stimulating hormone (FSH), luteinizing hormone (LH), and testosterone levels were evaluated before surgery. Multivariate analyses were conducted to determine clinical parameters that could predict overall sperm retrieval success. Further subgroup analysis was performed to determine the factors that the diagnosis of non-obstructive azoospermia (NOA) diagnosis and sperm retrieval success among patients with NOA. Results A total of 2,987 infertile men attended our clinic. Men with azoospermia (n=517) who met the inclusion criteria and did not fulfil any exclusion criteria were included in the study. The overall sperm retrieval success was 47.58%. Logistic regression revealed that FSH 7.76 mIU/mL (sensitivity: 60.1%, specificity: 63.3%, p<0.001); longest testicular axis length 3.89 cm (sensitivity: 33.6%, specificity: 41.6%); and varicocele (p<0.001) were independent factors for overall sperm retrieval. The FSH cutoff of 7.45 mIU/mL (sensitivity: 31.3%, specificity: 37.7%, p<0,001); longest testicular axis length 3.85 cm (sensitivity: 76.7%, specificity: 65.4%, p<0.001); and varicocele (p<0.001) were independent factors for NOA diagnosis. Varicocele was the only clinical parameter that significantly predicted the success of sperm retrieval in patients with NOA. Conclusions FSH, LH, longest testicular axis, and varicocele are among the clinical parameters that are useful for predicting overall sperm retrieval success and NOA diagnosis. However, varicocele is the only clinical parameter that significantly predicts sperm retrieval success in patients with NOA. High-quality studies are required to assess the other predictors of sperm retrieval success.

Abstract
Male factor infertility plays a role in approximately 30% of infertility cases. Various causes of male factor infertility exist including congenital, acquired, idiopathic, or environmental factors. Identifying the underlying etiology of male factor infertility is a key step toward providing appropriate counseling, effective treatment options, and improving outcomes for couples with infertility. Although the recent advances and developments in assisted reproductive technology have undoubtedly improved fertility outcomes, clinicians must understand the scope of reproductive urologists in the evaluation and treatment of male infertility to provide comprehensive counseling, appropriate referral, comprehensive evaluation, and correct surgical sperm retrieval techniques when needed.

The Possible Role of Prescribing Medications, Including Central Nervous System Drugs, in Contributing to Male-Factor Infertility (MFI): Assessment of the Food and Drug Administration (FDA) Pharmacovigilance Database. Brain Sci 2023; 13:1652. [PMID: 38137101 PMCID: PMC10741514 DOI: 10.3390/brainsci13121652] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/26/2023] [Revised: 11/21/2023] [Accepted: 11/23/2023] [Indexed: 12/24/2023] Open
Abstract
BACKGROUND A wide range of medications may have a possible role in the development of male-factor infertility (MFI), including various antineoplastic agents, testosterone/anabolic steroids, immunosuppressive drugs/immunomodulators, glucocorticosteroids, non-steroidal anti-inflammatory drugs, opiates, antiandrogenic drugs/5-alpha-reductase inhibitors, various antibiotics, antidepressants, antipsychotics, antiepileptic agents and others. We aimed at investigating this issue from a pharmacovigilance-based perspective. METHODS The Food and Drug Administration (FDA) Adverse Event Reporting System (FAERS) database was queried to identify the drugs associated the most with MFI individual reports. Only those drugs being associated with more than 10 MFI reports were considered for the disproportionality analysis. Proportional Reporting Ratios (PRRs) and their confidence intervals were computed for all the drugs identified in this way in January 2023. Secondary, 'unmasking', dataset analyses were carried out as well. RESULTS Out of the whole database, 955 MFI reports were identified, 408 (42.7%) of which were associated with 20 medications, which had more than 10 reports each. Within this group, finasteride, testosterone, valproate, diethylstilbestrol, mechloretamine, verapamil, lovastatin and nifedipine showed significant levels of actual disproportionate reporting. Out of these, and before unmasking, the highest PRR values were identified for finasteride, diethylstilbestrol and mechloretamine, respectively, with values of 16.0 (12.7-20.3), 14.3 (9.1-22.4) and 58.7 (36.3-95.9). CONCLUSIONS A variety of several medications, a number of which were already supposed to be potentially linked with MFI based on the existing evidence, were associated with significant PRR levels for MFI in this analysis. A number of agents which were previously hypothesized to be associated with MFI were not represented in this analysis, suggesting that drug-induced MFI is likely under-reported to regulatory agencies. Reproductive medicine specialists should put more effort into the detection and reporting of these adverse drug reactions.

Front Endocrinol (Lausanne) 2023; 14:1186257. [PMID: 38027205 PMCID: PMC10663326 DOI: 10.3389/fendo.2023.1186257] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 03/14/2023] [Accepted: 10/20/2023] [Indexed: 12/01/2023] Open
Abstract
Objective To investigate clinical and singleton newborn outcomes in fresh cycles of embryo transfer after intracytoplasmic sperm injection (ICSI-ET) with diverse sperm sources (ejaculate, epididymis, and testis) in patients with Oligoasthenospermia, obstructive azoospermia (OA) or non-obstructive azoospermia (NOA). Methods Patients who received fresh ICSI-ET for the first time at the First Affiliated Hospital of Zhengzhou University Reproductive Medicine Center between June 2011 and June 2021 were selected for this 10-year retrospective cohort analysis. After propensity score matching, only 1630 cycles were included in the investigation of ICS-ET clinical and singleton newborn outcomes in patients with Oligoasthenospermia, OA, and NOA using sperm from diverse sperm sources. Results After propensity score matching, our data revealed a negligible difference in baseline and cycle parameters among groups. In patients with Oligoasthenospermia and OA, different sperm sources do not appear to influence clinical pregnancy rates and live birth rates, nor do they influence newborn outcomes, such as newborn weight, premature birth rate, and neonatal sex ratio in singleton births, except for OA patients who use epididymal sperm having higher low birth weight (LBW) rates in singleton pregnancies than those who use testicular sperm. In addition, clinical pregnancy rates, live birth rates, singleton gestation birth weights, premature birth rates, and neonatal sex ratios were similar between patients with Oligoasthenospermia, OA, and NOA using testicular sperm. Conclusions Regardless of the type of male infertility (Oligoasthenospermia, OA, NOA) or sperm sources (ejaculate, epididymis, testis), a successful ICSI-ET procedure can result in similar clinical and neonatal outcomes, such as clinical pregnancy rate, live birth rate, abortion rate, neonatal birth weight and sex ratio of singleton pregnancies.

Understanding the Male Perspective: Evaluating Quality of Life and Psychological Distress in Serbian Men Undergoing Infertility Treatment. Life (Basel) 2023; 13:1894. [PMID: 37763298 PMCID: PMC10532577 DOI: 10.3390/life13091894] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/18/2023] [Revised: 08/06/2023] [Accepted: 09/06/2023] [Indexed: 09/29/2023] Open
Abstract
The experience of an infertility diagnosis and treatment imposes a profound burden on affected individuals, encompassing not only physical and medical aspects but also a plethora of psychological, social, and emotional factors. By employing a multimodal assessment featuring validated self-report questionnaires, physical measurements, and clinical records, the present study aimed to explore the quality of life and psycho-emotional distress of men undergoing infertility treatment in Serbia, thereby addressing the dearth of research on the underrepresented male perspective in this domain. Findings revealed diverse semen abnormalities among participants (n = 96, average age 37.69 ± 5.72), with significant associations between longer treatment durations and reduced sperm motility. The observed rates of men surpassing predetermined DASS-42 questionnaire thresholds for depression, anxiety, and stress in the analyzed cohort were 13.54%, 11.46%, and 22.92%, respectively. Summary scores in conceptual areas comprised in the SF-36 questionnaire ranged from 49.00 ± 6.25 for the mental health dimension to 90.16 ± 17.75 obtained in the physical functioning subscale. Patients with a longer treatment duration demonstrated lower scores in the role emotional domain, indicative of a less favorable emotional state. Expectedly, inverse correlations were found between the SF-36 mental health score and DASS-42 subscales. By addressing the existing knowledge gap and highlighting the unique needs of infertile men, the finding of this study may contribute to a more inclusive and holistic approach to infertility research and management.

Evaluating the Predictive Value of Diagnostic Testicular Biopsy for Sperm Retrieval Outcomes in Men with Non-Obstructive Azoospermia. J Pers Med 2023; 13:1362. [PMID: 37763130 PMCID: PMC10532560 DOI: 10.3390/jpm13091362] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/09/2023] [Revised: 08/27/2023] [Accepted: 09/04/2023] [Indexed: 09/29/2023] Open
Abstract
BACKGROUND Non-obstructive azoospermia (NOA) presents a challenge in male infertility management. This study aimed to assess the efficacy of diagnostic testicular biopsy (DTB) in predicting sperm retrieval success via therapeutic testicular biopsy (TTB) and to understand the role of systemic inflammation in microdissection testicular sperm extraction (mTESE) outcomes. METHODS A retrospective analysis was conducted on 50 NOA males who underwent mTESE at the University of Ioannina's Department of Urology from January 2017 to December 2019. All participants underwent thorough medical evaluations, including semen analyses and endocrinological assessments. RESULTS DTB did not detect spermatozoa in half of the patients who later showed positive sperm findings in TTB. Preoperative variables, such as age, plasma levels of follicle-stimulating hormone (FSH), luteinizing hormone (LH), total testosterone (TT), prolactin (PRL), estradiol (E2), and inflammation biomarkers (neutrophil-lymphocyte ratio (NLR), platelet-lymphocyte ratio (PLR), monocyte-eosinophil ratio (MER)), were not consistently predictive of sperm retrieval success. Notably, TTB-negative patients had elevated NLR and PLR values, suggesting a possible link between systemic inflammation and reduced sperm retrieval during mTESE. CONCLUSIONS The findings question the necessity of an initial DTB, which might provide misleading results. A negative DTB should not deter further TTB or intracytoplasmic sperm injection (ICSI) attempts. The study emphasizes the need for further research to refine diagnostic approaches and deepen the understanding of factors influencing sperm retrieval in NOA patients, ultimately enhancing their prospects of biological parenthood.

Basic Clin Androl 2023; 33:28. [PMID: 37558984 PMCID: PMC10413523 DOI: 10.1186/s12610-023-00195-x] [Citation(s) in RCA: 1] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/21/2022] [Accepted: 04/24/2023] [Indexed: 08/11/2023] Open
Abstract
BACKGROUND Testicular sperm aspiration (TESA) is widely used in the diagnosis and management of nonobstructive azoospermia. However, its ability for predicting microdissection testicular sperm extraction in nonobstructive azoospermia (NOA) patients with AZFc deletion remains uncertain. To investigate whether TESA affected the sperm retrieval rate (SRR) in NOA patients with AZFc deletion, a retrospective analysis of the clinical data of NOA patients with AZFc deletion who underwent microdissection testicular sperm extraction (micro-TESE) was conducted. The effects of age, testicular volume, follicle-stimulating hormone (FSH) levels, luteinizing hormone (LH) levels, testosterone (T) levels and TESA on the SRR were analyzed in this group of patients. RESULTS A total of 181 individuals had their sperm successfully collected and underwent micro-TESE, with an SRR of 67.4%. The patients were separated into two groups based on their micro-TESE results (sperm acquisition and nonsperm acquisition), with no significant variations in age, testicular volume, FSH levels, LH levels, or T levels between the two groups. There was no significant difference in the SRR between any of the groups into which patients were classified based on reproductive hormone reference value ranges. Binary logistic regression was used to explore the absence of significant effects of age, testicular volume, FSH levels, LH levels, and T levels on sperm acquisition in patients undergoing micro-TESE. In the preoperative testicular diagnostic biopsy group, the sperm acquisition and nonsperm acquisition groups had SRRs of 90.1% and 65.1%, respectively. More significantly, there was no significant difference in the SRR between the negative preoperative testicular diagnostic biopsy group and the nonpreoperative testicular diagnostic biopsy group (65.1 vs. 63.8%, p = 0.855). CONCLUSION There is a high probability of successful sperm acquisition in the testis of men undergoing micro-TESE. In this group of patients, age, testicular volume, FSH levels, LH levels, and T levels may have little bearing on the micro-TESE outcome. In patients whose preoperative TESA revealed the absence of sperm, the probability of obtaining sperm by micro-TESE remained high (65.1%); negative TESA results appeared to not influence the SRR (63.8%) in patients undergoing micro-TESE.

Abstract
OBJECTIVES To study how the semen microbiome profile in men with nonobstructive azoospermia (NOA) differs from that of fertile controls (FCs). DESIGN Using quantitative polymerase chain reaction and 16S ribosomal RNA, we sequenced semen samples from men with NOA (follicle-stimulating hormone >10 IU/mL, testis volume <10 mL) and FCs and performed a comprehensive taxonomic microbiome analysis. SETTING All patients were identified during evaluation at the outpatient male andrology clinic at the University of Miami. PATIENTS In total, 33 adult men, including 14 diagnosed with NOA and 19 with proven paternity undergoing vasectomy, were enrolled. MAIN OUTCOME MEASURES Bacterial species in the semen microbiome were identified. RESULTS Alpha-diversity was similar between the groups, suggesting similar diversity within samples, whereas beta-diversity was different, suggesting differences in taxa between samples. In the NOA men, the phyla Proteobacteria and Firmicutes were underrepresented, and Actinobacteriota were overrepresented compared with FC men. At the genus level, Enterococcus was the most common amplicon sequence variant in both groups, whereas 5 genera differed significantly between the groups, including Escherichia and Shigella, Sneathia, and Raoutella. CONCLUSION Our study showed significant differences in the seminal microbiome between men with NOA and fertile men. These results suggest a loss of functional symbiosis may be associated with NOA. Further research into the characterization and clinical utility of the semen microbiome and its causal role in male infertility is necessary.

Abstract
Substances such as tobacco and cannabis can negatively modulate seminal parameters and sex hormones and lead to fertility problems in males. The present study aimed to determine the effect of cigarettes, dipping tobacco, and cannabis on semen parameters and sex hormones in infertile males. A total of 160 infertile healthy participants (cigarette smokers n = 40, dipping tobacco users n = 40, cannabis users n = 40 and infertile controls n = 40) were included in the study. Fasting blood samples were collected from all the participants using the aseptic technique, and semen samples were collected by masturbation following sexual abstinence of 2-7 days. The levels of serum testosterone, follicle-stimulating hormone (FSH), and luteinizing hormone (LH) were determined using ELISA. The serum level of FSH was significantly higher in cannabis users relative to the control group (p = 0.043). A mild non-significant decrease in sperm count, serum LH and testosterone levels were observed in all drug users compared to controls. In conclusion, chronic use of tobacco and cannabis mildly modulates semen and hormonal parameters in infertile males.

Abstract
Spermatogenic arrest is a severe form of non-obstructive azoospermia (NOA), which occurs in 10-15% of infertile men. Interruption in spermatogenic progression at premeiotic, meiotic, or postmeiotic stage can lead to arrest in men with NOA. Recent studies have intensively focused on defining genetic variants underlying these spermatogenic arrests by making genome/exome sequencing. A number of variants were discovered in the genes involving in mitosis, meiosis, germline differentiation and other basic cellular events. Herein, defined variants in NOA cases with spermatogenic arrests and created knockout mouse models for the related genes are comprehensively reviewed. Also, importance of gene panel-based screening for NOA cases was discussed. Screening common variants in these infertile men with spermatogenic arrests may contribute to elucidating the molecular background and designing novel treatment strategies.

Abstract
OBJECTIVE To study the impact of testicular cancer composite stage and histology with semen parameters in preorchiectomy cryopreservation samples. METHODS We retrospectively collected semen parameter data, composite stage, and tumor histology for patients who cryopreserved sperm prior to orchiectomy for testicular cancer between 2006 and 2018. Stage I was considered localized disease, and Stages II and III were considered metastatic disease. The World Health Organization (WHO) 2010 semen parameter criteria was used to characterize lab values as normal or subnormal. Categorical and continuous variables were compared using Fisher's exact and Mann Whitney U tests, respectively. RESULTS Thirty eight patients with testicular cancer underwent preorchiectomy cryopreservation. The median age (IQR) of our cohort was 27 (23-32). Four patients (11%) had azoospermia. No significant differences were found in these semen parameters between Stage I and Stage II/III patients or between seminoma and NSGCT patients. Per WHO 2010 criteria, 7 patients (18%) had abnormal (below reference range) semen volume, 18 patients (47%) had abnormal total sperm counts, and 9 patients (24%) had abnormal motility percentage. Abnormal semen parameters were not significantly associated with tumor histology or stage. CONCLUSION To our knowledge, this is the first study to show that semen parameters are similar across all stages of testicular cancer. Prior studies have shown that delaying orchiectomy to cryopreserving sperm does not negative affect oncological outcomes. As a result, regardless of staging or histology, sperm banking should be recommended for patients with both localized and metastatic testicular cancer.

Abstract
INTRODUCTION In Senegal, marital infertility is a real problem for society. We undertook the study of this subject to make an analysis of the spermatic parameters of the infertile Senegalese man and to better understand the impact of testicular morphological anomalies on male fertility. PATIENTS AND METHODS We conducted a cross-sectional, descriptive, retrospective study of 100 infertile patients followed at the Histology-Embryology-Cytogenetics laboratory of UCAD in Dakar, during the year 2020. Sperm parameters, presence of varicocele, and testicular volume were evaluated in our patients. RESULTS/DISCUSSION The mean age of the patients was 35.17±8.7 years. A history of sexually transmitted infections was found in 57% of patients. The mean duration of infertility was 5.67±3.2 years. The mean sperm count was 14,871,230/ml±4,950,000. Necrospermia was the most frequent abnormality found (60%), followed by asthenospermia (51%). The high rate of necrospermia could be explained by the high frequency of sexually transmitted infections. Other abnormalities were oligospermia (48%, including 09% cryptospermia), azoospermia (19%), teratospermia (19%), and hypospermia (13%). The predominance of azoospermia and oligospermia should prompt a search for a genetic predisposition in these subjects. The mean testicular volume was 10.3±4.9 cc on the right and 9.5±4.8 cc on the left. A single or bilateral varicocele was found in 43% of subjects. Patients with azoospermia and teratospermia were associated with testicular hypotrophy with a significant value (p=0.04). CONCLUSION Overall, the senegalese man consulting for infertility is a young adult, married for an average of 5 years. Necrospermia is the most frequently found anomaly. The severity of both qualitative and quantitative abnormalities should lead to a systematic search for a genetic origin. The etiological research of infertile patients must be done within a multidisciplinary framework to propose better management of these patients.

Abstract
Men with nonobstructive azoospermia (NOA) face the dual problems of low sperm count and low sperm quality. Most men with NOA without a clear cause are classified as having idiopathic NOA (iNOA). Previous studies found that microbes exist in semen, and the semen microbes of NOA men are different from those of normal men. However, the relevant mechanism is not clear. In this study, we answered the three questions of "who is there," "what is it doing," and "who is doing it" by combining 16s rRNA, nontargeted metabolome detection and metabolite traceability analysis. We found that the composition and interaction of seminal plasma microbes in the iNOA group changed. Metabolite traceability analysis and metabolic pathway analysis revealed that microbial abnormalities in the NOA group were closely related to the decrease of microbial degradation of toluene and the increase of metabolism of fructose or mannose. In addition, the metabolic relationship between microbes and the host in male semen in iNOA revealed that such microbes can produce harmful metabolites that affect sperm quality, the microbes compete with sperm for essential nutrients, and their presence reduces sperm production of essential nutrients. IMPORTANCE Idiopathic nonobstructive azoospermia is one of the great challenges in assisted reproductive therapy. Although microdissection testicular sperm extraction technology is currently available, many men with iNOA still face the problem of poor sperm retrieval and poor sperm quality. The role of seminal plasma microbes in male disease has been continuously investigated since semen was demonstrated to harbor commensal microbes. To our knowledge, this is the first detailed description of the microbe-host relationship in iNOA semen. This study is an important complement to research on the treatment and etiology of iNOA and the rationale for our ongoing research.

Abstract
This study aimed to analyze the clinical effects of microdissection testicular sperm extraction (micro-TESE) surgery combined with an intracytoplasmic sperm injection (ICSI) regimen in the treatment of non-obstructive azoospermia (NOA) patients with different etiologies. In total, 128 NOA patients participated in this study, in which they received infertility treatment by micro-TESE surgery combined with an ICSI regimen, and all patients were divided into three groups [the Klinefelter syndrome (KS), the idiopathic and the secondary NOA groups]. In addition, the sperm retrieval rate (SRR), fertilization rate, embryo development status and clinical treatment effects were analyzed. Among the 128 NOA patients, the SRR of KS NOA patients was 48.65%, those of idiopathic and the secondary patients were 33.82% and 73.91%, respectively. Regardless of etiologies, there was no correlation with age, hormone value or testicular volume. Further analysis showed that the SRR of the KS group was positively related with testosterone (T) values, and the SRR of the secondary group had a positive relationship with follicle-stimulating hormone or luteinizing hormone values. In the subsequent clinical treatment, the retrieved sperm was subjected to ICSI and achieved good treatment effects, especially in the secondary group, and the implantation rate (55.56%) and clinical pregnancy rate (68.42%) were both higher than those of the idiopathic group (28.75% and 40.00%) and KS group (22.05% and 30.77%). Micro-TESE surgery combined with ICSI insemination is the most effective treatment regimen for NOA patients. The SRR of NOA patients with different etiologies are related to certain specific factors, and micro-TESE surgery seems to be the ideal and only way to have biological children.

Abstract
The aim of this study was to assess the consequences of treatment with pentoxifylline (PTX), an inducer of sperm motility, on sperm DNA fragmentation (SDF) and clinical characteristics in non-obstructive azoospermia (NOA) patients. The pilot study included 15 NOA patients. Half of each sperm sample before and after rapid freezing, was treated with PTX (3.6 mM /l, 30 min) as the PTX group and the remaining samples were considered as the control. SDF and sperm motility were assessed in each group. The clinical study comprised 30 fresh testicular sperm extractions (TESE) and 22 post-thawed TESE intracytoplasmic sperm injection cycles. Half of the mature oocytes from each patient were injected with PTX-treated spermatozoa and the remaining oocytes were injected with non-treated spermatozoa. Fertilization was assessed at 16 h post injection. Embryo transfer was carried out on day 2 after fertilization. Chemical pregnancy was assessed 2 weeks after transfer. PTX was found to significantly increase (P < 0.05) sperm motility. There was an insignificant difference in SDF rates between the groups (P > 0.05). In patient ovaries given fresh TESE, there was not any significant difference in clinical characteristics (P > 0.05). In patient ovaries given post-thawed TESE, there was a significant difference in the number of 2PN and in embryo formation (P < 0.05). Differences in the results of chemical pregnancy were insignificant (P > 0.05) between the groups. In addition, there was not any correlation between DNA fragmentation index and sperm motility and laboratory outcomes. Therefore, obtaining viable spermatozoa using PTX was more effective in post-thawed TESE regime patients in terms of 2PN and in embryo formation, deprived of damaging effects on sperm DNA integrity.

Abstract
In the treatment of infertile patients with non-obstructive azoospermia (NOA) caused by the deletion of the azoospermia factor c region (AZFc) on the Y chromosome, synchronous and asynchronous surgical strategies are discussed. Clinical data from NOA patients with the AZFc deletion who underwent micro-TESE were analyzed retrospectively. The sperm retrieval rate (SRR) and sperm utilization rate of synchronous and asynchronous operation groups were followed up and compared. The fertilization rate, high-quality embryo rate, clinical pregnancy rate, abortion rate, and cumulative live birth rate of ICSI in patients with successful sperm retrieval were compared between the two groups. The two groups had sperm utilization rates of 98.9% (93/94) and 50.0% (14/28), respectively. The asynchronous group's sperm consumption rates were much lower than those of the synchronous operation group. Fertilization rate, high-quality embryo rate, clinical pregnancy rate of fresh transfer cycle, abortion rate, and cumulative live birth rate of patients in the synchronous operation group with fresh sperm, and the asynchronous operation group with thawed sperm, respectively, were 30.6% vs 33.8%, 33.8% vs 40.7%, 40.0% vs 12.5%, 30.4% vs 7.1%. Between the two groups, there was no significant difference. This suggests that individuals with NOA caused by the AZFc deletion have a high possibility of successfully acquiring sperm using micro-TESE and ICSI to conceive their own offspring. Synchronous micro-TESE is recommended to improve sperm utilization rate and the cumulative live birth rate.

Abstract
PURPOSE Azoospermia, as the most severe form of male infertility, no longer indicates sterility due to modern medical advancements. The current diagnostic procedure based on testicular biopsy has several drawbacks which urges the development of novel, non-invasive diagnostic procedures based on biomarkers. In the last two decades, there have been many proteomics studies investigating potential azoospermia biomarkers. In this review, we aimed to provide a critical evaluation of these studies. EXPERIMENTAL DESIGN Published articles were gathered by systematic literature search using Pubmed, Science Direct, and Google Scholar databases until March 2022 and were further preselected to include only studies on human samples. RESULTS A detailed review of these studies encompassed the proteomics platforms, sources of material, proposed candidate biomarkers, and their potential diagnostic specificity and sensitivity. In addition, emphasis was put on the top, most identified and validated biomarker candidates and their potential for discriminating azoospermia types and subtypes as well as predicting sperm retrieval success rate. CONCLUSIONS Proteomics research of azoospermia has laid the groundwork for the development of a more streamlined biomarker testing. The future research should be focused on well-designed studies including samples from all types/subtypes as well as further testing of the most promising biomarkers identified so far.

Abstract
PURPOSE This systematic review and meta-analysis investigated the sperm retrieval rate (SRR) and pregnancy rate after testicular sperm extraction in men with azoospermia and those with a history of cryptorchidism treated by orchiopexy. MATERIALS AND METHODS The SRR and clinical pregnancy rate were investigated. We performed a sub-analysis that included factors such as bilaterality, age, and idiopathic non-obstructive azoospermia (iNOA). The analysis comprised 13 studies from January 1995 to July 2021. The data sources were PubMed/MEDLINE, Embase, and the Cochrane Library included "cryptorchidism", "orchidopexy", "azoospermia", and "testicular sperm extraction". RESULTS The overall mean SRR was 63.3% (95% confidence interval [CI], 57.6%-68.6%; I²=62.4%), and the overall mean clinical pregnancy rate was 30.1% (95% CI, 22.6%-38.8%; I²=69.9%). The meta-analysis comparing the SRR, there was no significant difference between patients with a history of bilateral and unilateral orchiopexy (relative risk [RR]=1.02; 95% CI, 0.89-1.16; p=0.79). Orchiopexy performed under the age of 10 years showed significantly increased SRR compared to the age of over 10 years (RR=1.25; 95% CI, 1.06-1.47; p=0.008). Azoospermic men with a history of cryptorchidism treated by orchiopexy had significantly higher SRR than iNOA (RR=1.90; 95% CI, 1.40-2.58; p<0.0001). CONCLUSIONS Men with azoospermia and a history of cryptorchidism treated by orchiopexy had significantly higher SRR than those with iNOA after testicular sperm extraction. Furthermore, patients who underwent orchiopexy before the age of ten years had significantly higher SRR than patients operated at an older than the age of ten years.

Abstract
Microdissection testicular sperm extraction (mTESE) has been proposed as a salvage treatment option for men with a previously failed classic TESE (cTESE), but data are scarce. We aimed to assess the outcome of and potential predictors of successful salvage mTESE in a cohort of men previously submitted to unfruitful cTESE. Data from 61 men who underwent mTESE after a failed cTESE between 01/2014 and 10/2020, at 6 tertiary-referral centres in Italy were analysed. All men were investigated with semen analyses, testicular ultrasound, hormonal and genetic blood testing. Pathological diagnosis from TESE was collected in every man. Descriptive statistics and logistic regression models were used to investigate potential predictors of positive sperm retrieval (SR+) after salvage mTESE. Baseline serum Follicle-Stimulating hormone (FSH) and total testosterone levels were 17.2 (8.6-30.1) mUI/mL and 4.7 (3.5-6.4) ng/mL, respectively. Sertoli-cell-only syndrome (SCOS), maturation arrest (MA) and hypospermatogenesis were found in 24 (39.3%), 21 (34.4%) and 16 (26.2%) men after cTESE, respectively. At mTESE, SR+ was found in 30 (49.2%) men. Patients with a diagnosis of hypospermatogenesis had a higher rate of SR+ (12/16 (75%)) compared to MA (12/21 (57.1%)) and SCOS (6/24 (25%)) patients at mTESE (p < 0.01). No clinical and laboratory differences were observed between SR+ and SR- patients at mTESE. There were no significant complications after mTESE. At multivariable logistic regression analysis, only hypospermatogenesis (OR 9.5; p < 0.01) was independently associated with SR+ at mTESE, after accounting for age and FSH.In conclusion, salvage mTESE in NOA men with previous negative cTESE was safe and promoted SR+ in almost 50%. A baseline pathology of hypospermatogenesis at cTESE emerged as the only independent predictor of positive outcomes at salvage mTESE.

Abstract
Infertility is experienced by 8%-12% of adults in their reproductive period globally and has become a prevalent concern. Besides routine therapeutic methods, stem cells are rapidly being examined as viable alternative therapies in regenerative medicine and translational investigation. Remarkable progress has been made in understanding the biology and purpose of stem cells. The affected pluripotent stem cells (iPSCs) and mesenchymal stem cells (MSCs) are further studied for their possible use in reproductive medicine, particularly for infertility induced by premature ovarian insufficiency and azoospermia. Accordingly, this study discusses current developments in the use of some kinds of MSCs such as adipose-derived stem cells, bone marrow stromal cells, umbilical cord MSCs, and menstrual blood MSCs. These methods have been used to manage ovarian and uterine disorders, and each technique presents a novel method for the therapy of infertility.

The developmental miR-17-92 cluster and the Sfmbt2 miRNA cluster cannot rescue the abnormal embryonic development generated using obstructive epididymal environment-producing sperm in C57BL/6 J mice. Reprod Biol Endocrinol 2022; 20:164. [PMID: 36451157 PMCID: PMC9710060 DOI: 10.1186/s12958-022-01025-x] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 07/01/2022] [Accepted: 10/16/2022] [Indexed: 12/03/2022] Open
Abstract
BACKGROUND Sperm, during epididymal transit, acquires microRNAs(miRNAs), which are crucial for embryonic development. However, whether sperm miRNAs influenced by an obstructive epididymal environment affect embryonic development remains unknown. METHOD The sham operation and vasectomy were performed in C57BL/6 J mice to create the control group (CON) and the obstructive epididymal environment group(OEE) group, respectively. The morphology of the testis and epididymis was observed using hematoxylin and eosin staining (HE staining) to establish the OEE mice model. The sperm quality test, intracytoplasmic sperm injection (ICSI), and epididymosomes fusion were employed to observe the effect of the obstructive epididymal environment on sperm and resultant embryonic development. The alteration of the sperm small RNA (sRNA) profile was analyzed by sRNA sequencing. RT-qPCR and DNA methylation were applied to observe the effect of obstructive epididymis on the expression of sperm miRNAs. The miRNAs microinjection was used to explore the impacts of sperm miRNAs on embryonic development. RESULTS We confirmed postoperative 8-week mice as the OEE mice model by examining the morphology of the testis and epididymis. In the OEE group, we observed that sperm quality degraded and the development potential of embryos was reduced, which can be saved by the normal epididymal environment. The sperm sRNA sequencing revealed that the expression of the developmental miR-17-92 cluster and the Sfmbt2 miRNA cluster was downregulated in the OEE group. The expression of these two miRNA clusters in epididymis was also downregulated and regulated by DNA methylation. However, the downregulation of either the miR-17-92 cluster or the Sfmbt2 miRNA cluster in normal zygotes did not impair embryonic development. CONCLUSION The obstructive epididymal environment influences sperm quality and resultant embryonic development, as well as the abundance of the developmental miR-17-92 cluster and the Sfmbt2 miRNA cluster in sperm, but these miRNA clusters are not the cause of abnormal embryonic development. It implies that epididymis is important in early embryonic development and may play a potential role in sperm epigenome.

Abstract
Disruption of blood-testis barrier (BTB) was a crucial pathological feature of diabetes induced-testicular injury at early phase. Aucubin (AU), a main active component in Eucommiae Cortex, has drawn attention for its benefits against male reproductive system disease. The current study was aimed at investigating the protective role of AU and exploring the underlying mechanism in diabetic model. A murine model of type 2 diabetes mellitus (T2DM) was induced by high-fat diet (HFD) combined with streptozocin (STZ). Testicular weight index and morphology, sperm quality, integrity of BTB and protein levels were analyzed. The underlying mechanism of the protective effect of AU was further explored in Sertoli cells (SCs) cultured with high glucose (HG). Our results showed AU inhibited testicular structural destruction, restored disruption of BTB and improved abnormal spermatogenic function in diabetic mice. Consistent with in vivo results, HG induced decreased transcellular resistance and increased permeability in SCs monolayers, while AU exposure reverses this trend. Meanwhile, reduced expression of Zonula occludin-1(ZO-1) and Connexin43(Cx43) in testicular tissue diabetic mice and HG-induced SCs was prominently reversed via AU treatment. Mechanistic studies suggested a high affinity interaction between AU and c-Src protein was identified based on molecular docking, and the activation of c-Src was significantly inhibited in AU treatment. Furthermore, AU significantly increased the expression of Cx43 and ZO-1 proteins HG-induced SCs, which can be further enhanced in gene-silenced c-Src cells to some extent. Our results suggested that AU ameliorated disruption of BTB and spermatogenesis dysfunction in diabetic mice via inactivating c-Src to stabilize cell junction integrity.

A Comparative Cross-Platform Analysis to Identify Potential Biomarker Genes for Evaluation of Teratozoospermia and Azoospermia. Genes (Basel) 2022; 13:genes13101721. [PMID: 36292606 PMCID: PMC9602071 DOI: 10.3390/genes13101721] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/19/2022] [Revised: 09/12/2022] [Accepted: 09/19/2022] [Indexed: 11/24/2022] Open
Abstract
Male infertility is a global public health concern. Teratozoospermia is a qualitative anomaly of spermatozoa morphology, contributing significantly to male infertility, whereas azoospermia is the complete absence of spermatozoa in the ejaculate. Thus, there is a serious need for unveiling the common origin and/or connection between both of these diseases, if any. This study aims to identify common potential biomarker genes of these two diseases via an in silico approach using a meta-analysis of microarray data. In this study, a differential expression analysis of genes was performed on four publicly available RNA microarray datasets, two each from teratozoospermia (GSE6872 and GSE6967) and azoospermia (GSE145467 and GSE25518). From the analysis, 118 DEGs were found to be common to teratozoospermia and azoospermia, and, interestingly, sperm autoantigenic protein 17 (SPA17) was found to possess the highest fold change value among all the DEGs (9.471), while coiled-coil domain-containing 90B (CCDC90B) and coiled-coil domain-containing 91 (CCDC91) genes were found to be common among three of analyses, i.e., Network Analyst, ExAtlas, and GEO2R. This observation indicates that SPA17, CCDC90B, and CCDC91 genes might have significant roles to play as potential biomarkers for teratozoospermia and azoospermia. Thus, our study opens a new window of research in this area and can provide an important theoretical basis for the diagnosis and treatment of both these diseases.

Taiwan J Obstet Gynecol 2022; 61:800-805.

Abstract
OBJECTIVE We present our study about the significance of karyotyping and azoospermia factor(AZF) analysis in patients with azoospermia or oligozoospermia. MATERIALS AND METHODS We retrospectively reviewed 141 Taiwanese patients with nonobstructive azoospermia and 45 Taiwanese patients with oligozoospermia at MacKay Memorial Hospital, Taiwan, from 2010 to 2021 to determine the significance of karyotyping and azoospermia factor analysis. The karyotyping was analyzed using the Giemsa banding method. The AZF microdeletions were determined using multiplex polymerase chain reaction using primers specifically flanking the AZF subregions. RESULTS We found that 7.80% of patients with nonobstructive azoospermia had AZF microdeletions and 19.86% of patients with nonobstructive azoospermia had chromosomal anomalies or polymorphic variations. Furthermore, 4.44% of patients with oligozoospermia had AZF microdeletions, and 4.44% of patients with oligozoospermia had chromosomal anomalies or polymorphic variations. CONCLUSION In this study, 25.53% of patients with nonobstructive azoospermia and 8.88% of patients with oligozoospermia had abnormal findings. The significance of karyotyping and azoospermia factor analysis is more critical in patients with nonobstructive azoospermia than patients with oligozoospermia. Both karyotyping and AZF analysis could prevent delayed treatment for male infertility through accurate diagnosis and appropriate treatment. The number of our patients with AZFc microdeletion was also higher than that of patients with AZFa or AZFb. The spermatogenic potential may gradually decline in patients with AZFc microdeletion. The earlier is the diagnosis, the earlier will be the retrieval of testicular spermatozoa.

Comparative proteomics analysis of human FFPE testicular tissues reveals new candidate biomarkers for distinction among azoospermia types and subtypes. J Proteomics 2022; 267:104686. [PMID: 35914715 DOI: 10.1016/j.jprot.2022.104686] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/01/2022] [Revised: 07/05/2022] [Accepted: 07/11/2022] [Indexed: 10/16/2022]
Abstract
Understanding molecular mechanisms that underpin azoospermia and discovery of biomarkers that could enable reliable, non-invasive diagnosis is highly needed. Using label-free data-independent LC-MS/MS acquisition coupled with ion mobility, we compared the FFPE testicular proteome of patients with obstructive (OA) and non-obstructive azoospermia (NOA) subtypes hypospermatogenesis (Hyp) and Sertoli cell-only syndrome (SCO). Out of 2044 proteins identified based on ≥2 peptides, 61 proteins had the power to quantitatively discriminate OA from NOA and 30 to quantitatively discriminate SCO from Hyp and OA. Among these, H1-6, RANBP1 and TKTL2 showed superior potential for quantitative discrimination among OA, Hyp and SCO. Integrin signaling pathway, adherens junction, planar cell polarity/convergent extension pathway and Dectin-1 mediated noncanonical NF-kB signaling were significantly associated with the proteins that could discriminate OA from NOA. Comparison with 2 transcriptome datasets revealed 278 and 55 co-differentially expressed proteins/genes with statistically significant positive correlation. Gene expression analysis by qPCR of 6 genes (H1-6, RANBP1, TKTL2, TKTL1, H2BC1, and ACTL7B) with the highest discriminatory power on protein level and the same regulation trend with transcriptomic datasets, confirmed proteomics results. In summary, our results suggest some underlying pathways in azoospermia and broaden the range of potential novel candidates for diagnosis. SIGNIFICANCE: Using a comparative proteomics approach on testicular tissue we have identified several pathways associated with azoospermia and a number of testis-specific and germ cell-specific proteins that have the potential to pinpoint the type of spermatogenesis failure. Furthermore, comparison with transcriptomics datasets based on genome-wide gene expression analyses of human testis specimens from azoospermia patients identified proteins that could discriminate between obstructive and non-obstructive azoospermia subtypes on both protein and mRNA levels. Up to our knowledge, this is the first integrated comparative analysis of proteomics and transcriptomics data from testicular tissues. We believe that the data from our study contributes significantly to increase the knowledge of molecular mechanisms of azoospermia and pave the way for new investigations in regards to non-invasive diagnosis.

Abstract
Introduction and importance: Infertility affects approximately 10–15% of couples worldwide. Several causes are incriminated such as hormonal abnormalities, infections, genetic disorders, testicular cancer, varicocele, and others. Herein, we report a case of an unusual association between testicular tuberculosis and microdeletion of the Y chromosome in an infertile patient and we discuss the diagnostic and therapeutic difficulties. Case presentation A 36-year-old patient, a smoker, with no previous history consulted our department for primary infertility for 2 years. The clinical examination was normal. The sperm count showed azoospermia. karyotype analysis confirmed the diagnosis of a microdeletion of the Y chromosome. A testicular biopsy was performed. The microscopic analysis did not find any sperm cells. However, the histopathological examination was in favor of testicular TB. The patient received 6 months of anti-TB treatment. He remained azoospermic. Clinical discussion Azoospermia is defined as the absence of sperm in the ejaculate in two different samples. This condition is classified as obstructive and non-obstructive. The etiology of this condition is either an intrinsic testicular deficiency or an insufficient production of gonadotropins. Genetic and chromosomal abnormalities should be investigated due to the higher incidence in azoospermic patients compared to the normal population. Testicular causes are dominated by infections, trauma, ischemia, and iatrogenic causes such as chemotherapy and radiotherapy. Genetic causes are dominated by Klinefelter syndrome and Y-chromosome microdeletions. Conclusion Azoospermia is a frequent cause of male infertility. Several causes are incriminated such as hormonal abnormalities, infections, genetic disorders, and others. In some cases, this condition can be multifactorial. Infertility affects approximately 10–15% of couples worldwide. Several causes are incriminated such as hormonal abnormalities, infections, genetic disorders, and others. In some cases, this condition can be multifactorial. We report a case of an unusual association between a microdeletion of the Y chromosome and testicular tuberculosis.

Andrologia 2022; 54:e14487. [PMID: 35725990 PMCID: PMC9541877 DOI: 10.1111/and.14487] [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: 01/13/2022] [Revised: 03/14/2022] [Accepted: 04/03/2022] [Indexed: 11/10/2022] Open
Abstract
Azoospermia is found in about 1% of men in the general population and in about 10%–15% of infertile men. Upon discovery of semen analysis abnormality, another test must be performed after an interval of 3 months before any other infertility work‐up. This research aimed at evaluating the benefit of waiting for the control test. This retrospective monocentric descriptive study was carried out in the fertility center of the University Hospital of Saint Etienne. All consecutive azoospermic patients diagnosed between January, 2012 and December, 2019 were included. For each patient, two consecutive semen analyses performed 3 months apart were studied. The main focas was on patients whose second semen analysis would have modified the infertility work‐up. Amongst the 172 cases under study, the second semen analysis revealed the presence of sperm for three men. Only one of these 3 modified semen analyses was normal. In the observed azoospermic population, sperm was found on the second test in 1.7%. An infertility assessment is necessary after the discovery of azoospermia in the first semen analysis in 99.5%. These results suggest that it is useless to wait three stressful months before starting an infertility assessment for azoospermic population.

Abstract
Azoospermia consists of a significant proportion of infertility aetiology in males. Although known genetic abnormalities may explain roughly the third of infertility cases, the exact aetiology is still unclear. Chromosomal microarrays are widely used to detect sub chromosomal abnormalities (e.g., microdeletions and microduplications). This study aimed to investigate aetiology in patients with idiopathic azoospermia by using the chromosomal microarray method to detect possible sub chromosomal changes. Twenty-eight patients (with a mean age of 30.4 ± 9 years) that had been diagnosed with idiopathic azoospermia between January 2019 and December 2020 were included in the study. Genomic DNA isolated from the blood of patients were amplified using polymerase chain reaction and was subjected to chromosomal microarray analysis. A total of six microdeletions were identified as clinically significant: one pathogenic copy number variation (CNV), four likely pathogenic CNVs, and one CNV of unknown clinical significance. However, clinical findings indicated that these microdeletions, with variable expression levels, may affect the spermatogenesis process and induce azoospermia. Future investigations regarding the functional effect of these deletions may contribute to our understanding of azoospermia aetiology.

Novel STAG3 variant associated with primary ovarian insufficiency and non-obstructive azoospermia in an Iranian consanguineous family. Gene 2022; 821:146281.

Abstract
Non-obstructive azoospermia (NOA) and primary ovarian insufficiency (POI) present the most severe forms of male and female infertility. In the last decade, the increasing use of whole exome sequencing (WES) in genomics studies of these conditions has led to the introduction of a number of novel genes and variants especially in meiotic genes with restricted expression to gonads. In this study, exome sequencing of a consanguineous Iranian family with one POI and two NOA cases in three siblings showed that all three patients were double homozygous for a novel in-frame deletion and a novel missense variant in STAG3 (NM_001282717.1:c.1942G > A: p.Ala648Thr; NM_001282717.1:c.1951_1953del: p. Leu652del). Both variants occur within a short proximity of each other affecting the relatively conserved armadillo-type fold superfamily feature. STAG3 is a specific meiotic cohesin complex component that interacts with the α-kleisin subunit through this feature. Protein homology modeling indicated that the in-frame deletion destabilizes kleisin biding by STAG3. Although the missense variant did not seem to affect the binding significantly, protein homology modeling suggests that it further destabilizes kleisin binding when in double homozygous state with the deletion. Our findings are in line with several other studies having associated deleterious variants affecting this region with male and female infertility in humans and mouse models. This is the first report associating an in-frame STAG3 variant with NOA and POI in a single family. SUMMARY SENTENCE: A patient with primary ovarian failure and her two brothers with non-obstructive azoospermia were double homozygous for a novel in-frame deletion and a novel missense variant in STAG3 that potentially disrupt the protein's meiotic functions.

Abstract
Objectives: To report on the outcomes and demographics of azoospermic couples undergoing microscopic testicular sperm extraction (micro-TESE) in a large tertiary referral centre. Subjects and methods: A retrospective study of patients undergoing micro-TESE in a tertiary referral centre from March 2015 to August 2019 was undertaken. Histopathology, patient demographics, comorbidities, patient factors and live birth outcomes were evaluated. Results: A total of 102 micro-TESEs were performed with a sperm retrieval rate (SRR) of 30.3%. The successful group had a mean age of 32.7 years and a mean body mass index (BMI) of 26.8 kg/m2. Female partners in the successful group had a mean age of 32.2 years. Twenty percent of female partners had infertility factors, 86.7% had no previous pregnancy and 13.3% had a previous miscarriage. The successful group had 15 live births (50%), while 20% had frozen their sperm. 93.3% achieved live birth from single embryo transfer and currently have unutilised embryos in cryostorage to possibly create siblings in the future. Twenty percent had more than one live birth from a single micro-TESE. Sertoli cell-only syndrome (SCOS) was identified in 57.5% of all cases. This was bilateral in 80% of these cases (four cases only sampled unilaterally due to previous orchidectomies). Of the SCOS group, six men went on to have successful sperm extraction (10%). The presence of previous urologic history/surgery increased the risk of azoospermia by 13%. Conclusion: Men with previous urological conditions have an increased risk of azoospermia. SCOS was identified in 57.5% of cases making it the most common histopathological diagnosis in azoospermic men. Based on our cohort, micro-TESE offers potential sperm retrieval in azoospermic men with SCOS. Successful sperm extraction in patients was associated with 50% live births and appeared to be unaffected by the presence of male/female factors. The number of live births could be higher as 20% had frozen their sperm. Concurrent female issues did not appear to affect successful outcome after micro-TESE, although numbers are small.

Abstract
BACKGROUND Non-obstructive azoospermia (NOA) is the most severe type of male infertility, affecting 1% of men worldwide. Most of its etiologies remain idiopathic. Although genetic studies have identified dozens of NOA genes, monogenic mutations can also account for a small proportion of idiopathic NOA cases. Hence, this genetic study was conducted to explore the causes of monogenic variants of NOA in a cohort of Chinese patients. METHODS Following the screening using chromosomal karyotyping, Y chromosome microdeletion analyses, and sex hormone assessments, subsequent whole-exome sequencing analysis was performed in 55 unrelated idiopathic NOA patients with male infertility to explore potential deleterious variants associated with spermatogenesis. We also performed Sanger sequencing to demonstrate the variants. Testicular biopsy or microsurgical testicular sperm extraction was also performed to confirm the diagnosis of NOA and identify spermatozoa. Hematoxylin and eosin staining was performed to assess the histopathology of spermatogenesis. RESULTS Abnormal testicular pathological phenotypes included Sertoli cell-only syndrome, maturation arrest, and hypospermatogenesis. Using bioinformatics analysis, we detected novel variants in two recessive genes, FANCA (NM_000135, c.3263C > T, c.1729C > G) and SYCE1 (NM_001143763, c.689_690del); one X-linked gene, TEX11 (NM_031276, c.466A > G, c.559_560del); and two dominant genes, DMRT1 (NM_021951, c.425C > T, c.340G > A) and PLK4 (NM_001190799, c.2785A > G), in eight patients, which corresponded to 14.55% (8/55) of the patients. CONCLUSION This study presented some novel variants of known pathogenic genes for NOA. Further, it expanded the variant spectrum of NOA patients, which might advance clinical genetic counseling in the future.

Front Vet Sci 2022; 9:865967. [PMID: 35433905 PMCID: PMC9010537 DOI: 10.3389/fvets.2022.865967] [Citation(s) in RCA: 8] [Impact Index Per Article: 4.0] [Reference Citation Analysis] [Abstract] [Grants] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/30/2022] [Accepted: 02/21/2022] [Indexed: 12/26/2022] Open
Abstract
Azoospermia, the lack of spermatozoa in the ejaculate, is the most common finding in infertile but otherwise healthy male dogs and represents an increasing reproductive health issue in men, too. The diagnosis can be further classified as non-obstructive azoospermia and obstructive azoospermia due to an obstruction of the deferent ducts. Although non-obstructive azoospermia comprises more than half of azoospermic cases in men and is a common cause of infertility in the male dog, knowledge of the underlying etiology and pathophysiology is still strongly limited, and much uncertainty exists about the true incidence and possible treatment options. Therefore, this study aims to investigate and characterize infertile canine patients in detail by combining results of andrological examinations (clinical parameters, semen analysis, bacterial examination of semen, and Brucella canis serology), endocrine analysis (luteinizing hormone, testosterone, estradiol-17ß, and thyroid function), analysis of the alkaline phosphatase in seminal plasma, and histological assessment of testicular biopsies of 10 azoospermic dogs. Our results not only verify non-obstructive etiology for 9/10 cases of canine azoospermia but also further identified significant histopathological changes of the testicular tissue with severely disrupted spermatogenesis, including fibrotic remodeling, vacuolization, Sertoli-cell-only syndrome, tubular shadows, and an increase of the interstitial and vascular area. In addition, three dogs showed local and six dogs generalized immune-cell infiltration, indicating chronic immune-mediated orchitis. Only in one case (no. 1) that no immune cells were found, and obstructive azoospermia was suspected due to low alkaline phosphatase activity. Furthermore, the detection of anti-thyroideal antibodies in two dogs indicates an autoimmune thyroid disease and a correlation between the occurrence of thyroidal disorders and azoospermia. Our results confirm previous findings and contribute additional evidence suggesting that chronic immune-mediated orchitis is the major cause of infertility in dogs. Further studies should focus on uncovering underlying inflammatory processes behind spermatogenic failure in these cases and identify possible treatment options to (re-)initialize spermatogenesis.

[PMID: 35547436 PMCID: PMC9086529 DOI: 10.7759/cureus.23998] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Journal Information] [Subscribe] [Scholar Register] [Accepted: 04/09/2022] [Indexed: 11/05/2022] Open
Abstract
Purpose Since mesh-related long-term morbidity like chronic groin pain and vas entrapment in patients with an inguinal hernia is a concern, tissue-based repairs should be revaluated. There have been few prospective studies comparing the outcomes of Lichtenstein's technique and Desarda's technique for the repair of uncomplicated inguinal hernias. So, we conducted this prospective study comparing the two techniques. Methods This is a single-center prospective observational study conducted for a period of one year (2019). The patients who underwent surgery for uncomplicated inguinal hernia either by Lichtenstein's technique or Desarda's technique were included in the study. The two techniques were compared with respect to recurrence rates, immediate postoperative pain, chronic groin pain, wound infection, and the time taken to return to activities of daily living (ADL). Results There was no significant difference in the recurrence rates, chronic groin pain, wound infection, or return to ADL between Lichtenstein's technique and Desarda's technique of inguinal hernia repair. The mean duration to return to ADL was lesser when patients underwent Desarda's repair though this difference was not significant. Conclusion Desarda's tissue repair was found comparable to Lichtenstein's mesh repair in terms of recurrence and postoperative morbidity, immediate postoperative pain, chronic groin pain, wound infection, and the time taken to return to ADL. Desarda's technique may be considered as an alternative to mesh-based repairs to avoid long-term mesh-related morbidity for uncomplicated indirect hernias in the younger population.
