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.

Abstract Study question What is the role of endocrine stimulation therapy prior to mTESE in men with hypogonadism and non obstructive azoospermia (NOA)? Summary answer In hypogonadal men there is a positive correlation between change of serum Testosterone (ΔT) before and after stimulation, and a successful mTESE. What is known already NOA is the most common cause of azoospermia and it is often associated with hypogonadism and testicular failure. It is common practice for endocrine stimulation therapies such as gonadotropines or selective estrogens receptor modulators to be used prior mTESE; however there is currently paucity of data regarding their efficacy. Study design, size, duration Retrospective analysis on infertile men with hypogonadism (defined as T < 12nmol/L) and NOA who underwent mTESE with or without prior endocrine stimulation therapy (clomiphene or human chorionic gonadotropin). Retrospective data from 2015–2020, total number of patient: 71; stimulated group (N:40) vs unstimulated group (N:31). Participants/materials, setting, methods Retrospective study on infertile men who underwent mTESE with or without prior endocrine stimulation therapy. Hypogonadism was defined as serum testosterone (T) level <12nm/L. We recorded demographic data, cause of testicular failure, previous testosterone therapy, duration and type of endocrine stimulation, pre-and post-stimulation hormone levels(T, FSH, LH), pre-operative hormone levels, successful sperm retrieval rate (at least 1 vial of viable sperm), average Johnsen score and total number of vials of sperm retrieved. Main results and the role of chance One-hundred-sixty-eight men underwent mTESE out of which 59 men received endocrine stimulation therapy for NOA between 2015–2020. Among them, we selected men with hypogonadism defined as serum T < 12nmol/L which comprised 43% of the entire patient cohort. The hypogonadal group included 71 men, 28/71 had Klinefelter syndrome and 40/71 received endocrine stimulation for 13.9±9.2 months. Testosterone levels significantly increased after endocrine stimulation (6.3±3.3nm/L vs 11.7±7.4nm/L) with mean change in serum testosterone (ΔT) of 5.7 nm/L (–5.5–23.3, N35). In the stimulated group, pre-operative serum T levels were significantly higher (11.7±7.4 vs 7.8±3.0 p:0.007) as compared to unstimulated men but the success rate of mTESE did not differ significantly (16/40–40%) vs 13/31–42%). Men with Klinefelter syndrome demonstrated significant differences with regards to age, lower T levels, higher FSH and LH levels, lower Johnsen score and success rates compared to other causes of NOA. Comparing men who had successful mTESE vs unsuccessful mTESE - higher T and lower FSH and LH seemed to correlate with successful sperm retrieval. Among men who received endocrine stimulation therapy the ΔT before and after stimulation seemed to correlate with successful sperm retrieval (AUC:0.701, SE:0.089, p:0.043). In the stimulated group a ΔT>3.5nm/L showed a significant association with successful mTESE(p:0.041). Limitations, reasons for caution Retrospective study limitations. Wider implications of the findings: Our study shows a significant improvement of serum T following endocrine stimulation therapy. Overall, in hypogonadal men, the hormonal stimulation seems not to be related to a higher success rate of mTESE but our data do suggest a positive correlation between ΔT before and after stimulation, and a successful mTESE.

Abstract Background Varicocele is an abnormal dilation and tortuosity of the internal spermatic veins within the pampiniform plexus of the spermatic cord. Varicocele is associated with progressive testicular damage and infertility. Azoospermia is associated with a varicocele in approximately 4–14% cases. For men with azoospermia or severe oligoasthenospermia, varicocele repair may result in modest improvement in semen quality which may have a significant advantage on couple’s fertility options. The aim of the study was to evaluate the role of microsurgical varicocelectomy in the men of non-obstructive azoospermia (NOA) with clinical varicocele. Methods This was a retrospective study conducted between August 2012 and January 2017, a backward review of 104 patients with the diagnosis of infertility and NOA with palpable varicocele that underwent microsurgical varicocelectomy at our institution was performed. In addition, microdissection testicular sperm extraction (MDTESE) results of these post-varicoceletomy patients were compared with the patients of NOA without varicocele. Results A total of 104 patients underwent varicocelectomy; out of these, 19 patients (18.26%) had sperm on sperm analysis post-operatively. Two of them had spontaneous pregnancy (10.5%), and 3 had children by intracytoplasmic sperm injection (15.78%). Out of the 85 patients who had MDTESE, 29 patients (34.11%) had sperms in their testis. The fertilization rate was 89.65%. Sperm retrieval rate (SRR) in NOA men with varicocele was 34.11% which was higher from those who had NOA without varicocele (24.03%). Live birth rate was 31.03% in NOA men who had varicocelectomy which was more in comparison to NOA men without varicocele (24%). Conclusions In NOA men with varicocele microsurgical varicocelectomy may have favourable effects which results in recovery of motile sperms in the post-operative ejaculate and also on spontaneous or assisted pregnancies, but it appears that this effect was more remarkable on MDTESE results when following successful intracytoplasmic sperm injection. Importantly, Sperm retrieval rate, pregnancy rate and subsequent live birth rate were higher in these patients in comparison to patients affected by NOA alone. In patients with NOA and coexisting varicocele, varicocelectomy can be considered to be essential to the overall reproductive outcome in these patients.

Surgical sperm retrieval combined with the advent of in vitro fertilization and intracytoplasmic sperm injection has enabled many men with obstructive and non-obstructive azoospermia to father their own biological children. Several sperm retrieval techniques have been described to obtain sperm from the vas deferens, epididymis, and testicular parenchyma for use in assisted reproduction technologies. The current techniques have variable success rates but have not been subjected to randomized control trials hence the paucity of good evidence to inform the choice of one technique over the others. In experienced hands, sufficient and good quality sperm can usually be harvested for treatment and/or cryopreservation. This chapter summarizes the current techniques of surgical sperm retrieval, sperm retrieval success rate, and the role of adjuvant therapies in increasing chance of successful sperm retrieval.

In the second part of the review, devoted to treatment of azoospermia by micro-TESE in program IVF/ICSI, there were considered issues of hormonal preparation of patients with non-obstructive azoospermia (NOA) prior to the course of GnRH, chorionic and menopausal gonadotropin treatment. Sperm retrieval efficiency increases after stimulation of spermatogenesis 6 months. Identification of additional factors such as FSH, AMH, and Inhibin B in blood serum and seminal plasma can provide more accurate prognosis of the outcome of micro-TESE. High level of FSH is not a contraindication for microsurgical sperm retrieval in men with NOA. Neither level of FSH nor testicular volume is related to the effectiveness of operation. Molecular genetic markers of residual spermatogenesis (ESX1, VASA and CLU genes) can serve as predictors of successful sperm retrieval during micro-TESE in patients with NOA. In the review there were also considered advantages of microdissection technique, technique of operation performance (including embryological stage of detection of spermatozoa in testicular tissue), and efficiency of micro-TESE depending on pathological patterns and complications after surgery.

<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>
