Abstract Objectives: to determine the ability of pre-surgical markers to predict the ability to retrieve sperm in non-obstructive azoospermia (NOA) undergoing surgical sperm retrieval. Methods: a cross-sectional descriptive analysis of 136 infertile patients with azoospermia, examined in the Hue Center for Reproductive Endocrinology and Infertility (HUECREI), Hue University Hospital from August 2014 to July 2018. Patients underwent surgical sperm retrieval in a stepwise manner via percutaneous epididymal sperm aspiration (PESA), testicular sperm aspiration (TESA) then testicular sperm extraction (TESE) until sperm were detected. Patient age, duration of infertility, body mass index (BMI), hormonal profile (FSH, LH & testosterone), and testicular volume were analyzed to determine the predictor of successful sperm retrieval. Analysis was done by univariate & multivariate generalized estimating equation modeling where the primary outcome was sperm retrieved at surgery. Results: In total of 136 infertile men with azoospermia, beside 45 cases with OA, surgical sperm retrieval was successful in 22/91 patients with NOA (24.2%). The group of men with successful sperm retrieval were more likely to live in urban area (P=0.012), higher proportion of normal testicular density (P<0.05), lower serum FSH and serum LH (P<0.001). By multiple logistic regression model, total testicular volume was found to be a only considerable predictor of sperm retrieval in NOA group (OR 1.09, 95%CI 1.013-1.178, P=0.022). Conclusions: The measurement of total testicular volume can be helpful for predicting the successful result of surgical sperm retrieval in Vietnamese infertile men with non-obstructive azoospermia. Key words: testicular ultrasound; endocrine profile; surgical sperm retrieval; non-obstructive; azoospermia.

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.

Objectives: This study aimed to determine the role of presurgical markers in the prediction of sperm retrieval by conventional Multiple Testicular Sperm Extraction in infertile Vietnamese men with nonobstructive azoospermia (NOA). 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 conventional multiple testicular sperm extraction in up to three locations, and procedures stopped as soon as sperm were detected. Factors were analyzed to determine the prediction of the likelihood of successful sperm retrieval, in men with NOA. Results: The overall success rate of sperm retrieval in men with azoospermia was 49.3%, but it was only 18.4% in NOA group. The difference in testicular volume between men with successful sperm retrieval and unsuccessful sperm retrieval was not statistically significant in NOA group (5.68 ± 2.37 vs. 4.46 ± 2.83, p = 0.138). The differences in the endocrine tests between the two groups were also not significant in terms of luteinizing hormone (LH), follicle-stimulating hormone (FSH), and testosterone (p ¿ 0.05). Multivariable analysis of predictive factors of sperm retrieval in NOA groups found no significant difference, except testicular density (p = 0.015). Conclusions:In infertile men with NOA, neither an endocrine test nor testicular volume should be used for predicting the results of surgical sperm retrieval by conventional multiple testicular sperm extraction.

<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: 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.

Azoospermia is divided into two categories of obstructive azoospermia and non-obstructive azoospermia. Before 1995, couples with a male partner diagnosed with non-obstructive azoospermia had to choose sperm donation or adoption to have a child. Currently, testicular sperm aspiration or micro-dissection testicular sperm extraction combined with intracytoplasmic sperm injection allows patients with non-obstructive azoospermia to have biological offspring. The sperm retrieval rate is significantly higher in micro-dissection testicular sperm extraction compared with testicular sperm aspiration. Additionally, micro-dissection testicular sperm extraction has the advantages of minimal invasion, safety, limited disruption of testicular function, a low risk of postoperative intratesticular bleeding, and low serum testosterone concentrations. Failed micro-dissection testicular sperm extraction has significant emotional and financial implications on the involved couples. Testicular sperm aspiration and micro-dissection testicular sperm extraction have the possibility of failure. Therefore, predicting the sperm retrieval rate before surgery is important. This narrative review summarizes the existing data on testicular sperm aspiration and micro-dissection testicular sperm extraction to identify the possible factor(s) that can predict the presence of sperm to guide clinical practice. The predictors of surgical sperm retrieval in patients with non-obstructive azoospermia have been widely studied, but there is no consensus.
