Abstract Purpose The purpose of this study is to assess a potential association between FSH levels and testicular volumes with the severity of testicular histopathology on testicular biopsy in men with non-obstructive azoospermia (NOA) undergoing microdissection testicular sperm extraction (microTESE). Methods A retrospective chart review was performed from the electronic health records of men who underwent microTESE with NOA. Results Eighty-six men with NOA underwent microTESE with concomitant testicular biopsy for permanent section to assess the testicular cellular architecture. The histopathological patterns were categorized by severity indicating the odds of sperm retrieval into 2 categories. The unfavorable category included Sertoli cell only pattern and early maturation arrest (n = 50) and the favorable category included late maturation arrest and hypospermatogenesis patterns (n = 36). In the men with unfavorable histopathologic patterns, the mean FSH level was 22.9 ± 16.6 IU/L, and the mean testicular volume was 10.4 ± 6.0 cc. This was in comparison to men with favorable histopathologic patterns revealing a mean FSH level of FSH 13.3 ± 12.0 with a mean testicular volume of 13.3 ± 5.9 cc. There was a statistically significant higher FSH level in men with unfavorable histopathology than favorable (p = 0.004) as well as a significant smaller mean testicular volume in men with unfavorable histopathology (p = 0.029). Conclusions Higher serum FSH levels and smaller testicular volumes are associated with more severe testicular histopathological patterns in men with NOA.

<p><strong>Objective:</strong> Non-obstructive azoospermia, defined as absence of spermatozoa in the ejaculate caused by impaired spermatogenesis, is the most severe cause of male infertility. It is typically presented as high serum follicle stimulating hormone levels and atrophic testis. The combination of intracytoplasmic sperm injection and Microdissection testicular sperm extraction allows these infertile men the opportunity to have their own children from their own testis. Our aim was to evaluate the outcomes of micro-Testicular sperm extraction in men with atrophic testis.</p><p><strong>Study Design:</strong> The medical records of 80 non-obstructive men with azoospermia who underwent micro-TESE were retrospectively evaluated. We assessed clinical parameters; age, duration of infertility, smoking, chromosomal karyotype, Y chromosome microdeletion, follicle stimulating hormone, luteinizing hormone, total testosterone and testicular volume in relation with Microdissection testicular sperm extraction results.</p><p><strong>Results:</strong> Testicular sperm retrieval rate was 53% in 80 patients. Testicular volume, serum follicle stimulating hormone and total testosterone concentrations showed correlation with the results of sperm retrieval. These three parameters were found to be significant risk factors with testicular sperm extraction negative patients (p&lt;0.001). The odds ratios (95% CI) were 6.39 (1.25–26.58), 1.24 (1.11-1.36), 1.13 (0.99-1.21) respectively. Testicular volume was found to be a discriminative parameter in patients with negative sperm retrieval. The cut-off point was established as 6.75 ml for testicular volume with 88.1% sensitivity, 62.1% specificity.</p><p><strong>Conclusion:</strong> Microdissection testicular sperm extraction is the most effective procedure for patients with non-obstructive azoospermia. Testicular volume, serum follicle stimulating hormone and testosterone levels can be predictive factors for sperm retrieval in men with non-obstructive azoospermia.</p>

Abstract The aim of the current study was to investigate the predictive markers for males with non-obstructive azoospermia (NOA) before they received conventional testicular sperm extraction (cTESE) or microdissection testicular sperm extraction (microTESE). Between January 2010 and December 2020, a total of 56 patients who received cTESE or microTESE surgery at the Urology department of the MacKay Memorial Hospital were included. Our univariate analysis revealed that the following parameters was associated with sperm retrieval: Follicle-stimulating hormone (FSH), luteinizing hormone (LH), prolactin, testicular volume, histopathology of maturation arrest and Sertoli cell-only. The multivariate analysis showed that Sertoli cell-only was significantly less likely to harvest spermatozoa than normal spermatogenesis (OR = 0.03 (0.002-0.42); p = 0.01). A comparison of cTESE and microTESE revealed that the overall successful sperm retrieval rate was not significantly different between the two methods (74.1% vs. 58.6, p = 0.22). This study demonstrated that lower levels of FSH, LH and prolactin, and a higher testicular volume and better histopathology were associated with a higher sperm retrieval rate in the univariate analysis. In the multivariable analysis, only Sertoli cell-only syndrome appeared to have a significantly negative effect on the successful harvesting of sperm when compared with normal spermatogenesis.

Background: Microdissection testicular sperm extraction (mTESE) is the gold standard approach in sperm retrieval in men with non-obstructive azoospermia (NOA). The purpose of the study was to assess the outcomes for Irish men who have undergone mTESE with a single surgeon. Methods: This is a retrospective, single cohort study. Thirty-four patients underwent mTESE between September 2015 and June 2019. A p<0.05 was considered statistically significant. Results: In this study, sperm retrieval rate (SRR) was 47.06%. (16/34). The mean age in those who had retrieved sperm at mTESE was 37.9±2.6 years. Johnson Score (JS) and FSH were statistically different between successful and unsuccessful mTESE groups (p=0.017*10-5 and p=0.004, respectively). Optimal cutoff values for FSH, T and JS were 15 IU/L, 13 nmol/L and 5, respectively. The pregnancy rate was 63.64% (7/11) among men who went on to use mTESE sperm in an ICSI cycle. Conclusion: The combination of mTESE/Intracytoplasmic sperm injection (ICSI) is the best option available for men with NOA who prefer to achieve paternity using their own DNA. Given the overall SRRs in mTESE, it is imperative to continue research for a predictive model to better counsel azoospermic men regarding the use of mTESE. For this purpose, large, multicenter, randomized controlled trials are needed.

Abstract Objectives: This study aimed to determine the role of pre-surgical markers in the prediction of sperm retrieval in infertile Vietnamese men with azoospermia. Patients and Methods:Retrospective descriptive analysis of 136 infertile men with azoospermia, examined from August 2014 to July 2018. Patients underwent stepwise surgical sperm retrieval via percutaneous epididymal sperm aspiration, testicular sperm aspiration then multiple testicular sperm extraction in up to 3 locations until sperm were detected. Factorswere analyzed to determine the prediction of sperm retrieval.Results: The overall success rate of sperm retrieval was 49.3% including 88.3% and 18.4% in the OA and NOA group, respectively. The results of sperm retrieval were significantly associated only with the OA and NOA group, not with endocrine test or testicular volume. We found no significant difference in the endocrine test and testicular volume’s result between successful and unsuccessful sperm retrieval in either group.Conclusions: Neither an endocrine test nor testicular volume should be used for predicting the results of surgical sperm retrieval in infertile Vietnamese males with azoospermia.

Introduction: The aim of our research was to establish the relevance of testicular histopathology on sperm retrieval after testicular sperm extraction in patients with non-obstructive azoospermia and in patients with obstructive azoospermia, who already underwent a previous failure testicular fine needle aspiration. Methods: We evaluated a total of 82 azoospermic men, underwent testicular sperm extraction, referring to the Assisted Reproductive Technology Centre of the University of Florence, Italy between January 2008 and March 2017. A general and genital physical examination, scrotal and trans-rectal ultrasound, semen analysis, hormone measurements, including follicle-stimulating hormone, luteinizing hormone and total testosterone, were collected. Results: Successful sperm retrieval was obtained in 36 men of total (43.9%). Successful sperm retrieval was 29.5% in non-obstructive azoospermia patients, while men with obstructive azoospermia, who, underwent a previous failure testicular fine needle aspiration, had sperm retrieval in 86% of cases. Mean luteinizing hormone was 6.55 IU/L, total testosterone 4.70 ng/mL, right testicular volume 13.7 mL and left testicular volume 13.6 mL. Mean Follicle-stimulating hormone was 13.45 IU/L in patients with negative sperm retrieval and 8.18 IU/L in men with successful sperm retrieval. According to histology, 20.7% had normal spermatogenesis, 35.3% hypospermatogenesis, 35.3% maturation arrest and 8.5% Sertoli cell-only syndrome. Successful sperm retrieval was 88.2% in patients with normal spermatogenesis, 24.1% in the maturation arrest group and 48.27% in patients with hypospermatogenesis, while negative sperm retrieval was reported in Sertoli cell-only syndrome patients. Seven cases with maturation arrest showed a successful sperm retrieval. Conclusion: Testicular histopathology after testicular sperm extraction offers important information on prediction of sperm retrieval and can guide the surgeon in choosing the more suitable therapeutic practice.

Objective: To observe the clinical practice of salvage microdissection testicular sperm extraction (mTESE) in patients with non-obstructive azoospermia (NOA) and to determine the factors that may predict the presence of spermatozoa in preoperative salvage mTESE. Methods: We retrospectively reviewed the medical records of 445 patients with the diagnosis of NOA, who had undergone the mTESE operation consecutively in our institution between the dates of March 2008 and June 2017. The study included a total of 49 patients with failure to detect spermatozoa in the first mTESE and who had then undergone salvage mTESE. In order to investigate the factors that predict the result of salvage mTESE, the patients were classified into two groups according to the outcome of salvage mTESE, as those with and without spermatozoa retrieval. Patients in these two groups were compared with regard to age, body mass index, history of varicocele, history of cryptorchidism, duration of infertility, outcomes of genetic analysis, results of hormone profiles and the testicular histopathology results of the first mTESE. Results: The sperm retrieval rate following salvage mTESE was observed to be 42.8%. Statistically a significant difference was determined between the mean follicle stimulating hormone (FSH) values of the groups (p = 0.013). No significant difference was observed between the groups with regard to the remaining parameters.Conclusion: It was observed that among the factors that predict the success of sperm retrieval in salvage mTESE in patients with NOA and previous unsuccessful sperm retrieval in mTESE operation, only the pre-operative FSH level was observed to significantly correlate with the success in salvage mTESE.

Abstract Background Non-obstructive azoospermia (NOA) is the most severe form of male infertility. More than half of the NOA patients were idiopathic for their etiology, in whom it’s difficult to retrieve sperm despite the application of microsurgical testicular sperm extraction (microTESE). Therefore, we conducted to this study to identify the potential genetic factors responsible for NOA, and investigate the sperm retrieval rate of microTESE for the genetic defected NOA.Methods One NOA patient from a consanguineous family (F1-II-1) and fifty NOA patients from non-consanguineous families were included in the study. Semen analyses, chromosome karyotypes, screening of Y chromosome microdeletions, sex hormone testing, and subsequent testicular biopsy were performed to categorize NOA or obstructive azoospermia. Potentialgenetic variants were identified by whole exome sequencing (WES),and confirmed by Sanger sequencing in F1 II-1. The candidate genes were screened in the other fifty NOA patients. Further experiments including quantitative real time-polymerase chain reaction and western blotting were performed to verify the effects of gene variation on gene expression.Results Normal somatic karyotypes and Y chromosome microdeletions were examined in all patients. Hematoxylin and eosin staining (H&E) of the testicular tissues suggested meiotic arrest, and a novel homozygous HFM1 variant (c.3490C>T: p.Q1164X) was identified in F1 II-1. Furthermore, another homozygous HFM1 variant (c.3470G>A: p.C1157Y) was also verified in F2 II-1 from the fifty NOA patients. Significantly decreased expression levels of HFM1 mRNA and protein were observed in the testicular tissues of these two mutants compared with controls. MicroTESE was performed in these two patients, while no sperm were retrieved. Conclusions Our study identified two novel homozygous variants of HFM1 that are responsible for spermatogenic failure and NOA, even microTESE can not contribute to retrieve sperm in these patients.

Background: There are some men suffer from infertility, non-obstructive azoospermia is one of the causes of infertility, these men need sperm retrieval from testes like microdissection testicular sperm extraction (Micro-TESE). This work aims to assess the different preoperative and intraoperative factors that predict successful sperm retrieval with Microdissection Testicular Sperm Extraction (Micro-TESE) in men with non-obstructive azoospermia. Methods: Our study is a cohort prospective one, conducted on 52 male patients with non-obstructive azoospermia who attended to the outpatient andrology and infertility clinic of Urology Department, Tanta University Hospitals during the period between December2018 to November2019. All patients were subjected to detailed medical history, physical examination, two semen analysis on two different laboratories. Microdissection Testicular Sperm Extraction is performed to all patients after Estimation of serum FSH, LH, testosterone, prolactin, estradiol and scrotal Doppler ultrasonography Results: From 52 patients who have done, Patients were divided in to 2 groups according to the result of Micro-TESE procedure: negative SSR group (28 patients) and positive SSR group (24 patients).In comparison between the two groups according to preoperative factors as age, FSH, LH, estradiol, testosterone, prolactin and testicular volume, there was no significant difference between these groups. On comparison of intraoperative size of seminiferous tubules in relation to results of Micro-TESE, we found that presence of large convoluted seminiferous tubules was statistically significant in prediction of successful sperm retrieval with Micro-TESE Conclusions: The chances of sperm retrieval in men with NOA by Micro-TESE are not related to preoperatively age, FSH, LH, testosterone, estradiol, prolactin and testicular volume. The detection of large seminiferous tubules intraoperatively is a good predictor for successful sperm retrieval with Micro-TESE as it was statistically significant.

Abstract Background Non-obstructive azoospermia (NOA) is the most severe form of male infertility; more than half of the NOA patients are idiopathic. Although many NOA risk genes have been detected, the genetic factors for NOA in majority of the patients are unknown. In addition, it is difficult to retrieve sperm from these patients despite using the microsurgical testicular sperm extraction (microTESE) method. Therefore, we conducted this genetic study to identify the potential genetic factors responsible for NOA and investigate the sperm retrieval rate of microTESE for genetically deficient NOA patients. Methods Semen analyses, sex hormone testing, and testicular biopsy were performed to categorize the patients with NOA. The chromosome karyotypes and Y chromosome microdeletion analyses were used to exclude general genetic factors. Whole exome sequencing and Sanger sequencing were performed to identify potential genetic variants in 51 patients with NOA. Hematoxylin and eosin staining (H&E) and anti-phosphorylated H2AX were used to assess the histopathology of spermatogenesis. Quantitative real time-polymerase chain reaction, western blotting, and immunofluorescence were performed to verify the effects of gene variation on expression. Results We performed whole exome sequencing in 51 NOA patients and identified homozygous helicase for meiosis 1(HFM1) variants (NM_001017975: c.3490C > T: p.Q1164X; c.3470G > A: p.C1157Y) in two patients (3.9%, 2/51). Histopathology of the testis showed that spermatogenesis was completely blocked at metaphase in these two patients carrying the HFM1 homozygous variants. In comparison with unaffected controls, we found a significant reduction in the levels of HFM1 mRNA and protein expression in the testicular tissues from these two patients. The patients were also subjected to microTESE treatment, but the sperms could not be retrieved. Conclusions This study identified novel homozygous variants of HFM1 that are responsible for spermatogenic failure and NOA, and microTESE did not aid in retrieving sperms from these patients.
