In this review, we tried to systematize all the evidence (from PubMed [MEDLINE], Scopus, Cochrane Library, EBSCO, Embase, and Google Scholar) from 1993 to 2021 on the predictors of microsurgical varicocelectomy efficacy in male infertility treatment. Regarding the outcomes of varicocele repair, we considered semen improvement and pregnancy and analyzed them separately. Based on the 2011 Oxford CEBM Levels of Evidence, we assigned a score to each trial that studied the role of the predictor. We systematized the studied predictors based on the total points, which were, in turn, calculated based on the number and quality of studies that confirmed or rejected the studied predictor as significant, into three levels of significance: predictors of high, moderate, and low clinical significance. Preoperative total motile sperm count (TMSC) coupled with sperm concentration can be a significant predictor of semen improvement and pregnancy after varicocelectomy. In addition, for semen improvement alone, scrotal Doppler ultrasound (DUS) parameters, sperm DNA fragmentation index (DFI), and bilateral varicocelectomy are reliable predictors of microsurgical varicocelectomy efficacy.

The authors performed a comprehensive review of current literature to create a model comparing commonly evaluated variables in male factor infertility, for example, follicle-stimulating hormone (FSH), testicular volume (TV), and testosterone (T), to better predict sperm retrieval rate (SRR). Twenty-nine studies were included, 9 with data on conventional testicular sperm extraction (cTESE) for a total of 1227 patients and 20 studies including data on microdissection testicular sperm extraction (mTESE) for a total of 4760 patients. A weighted-means value of SRR, FSH, T, and TV was created, and a weighted linear regression was then used to describe associations among SRR, type of procedure, FSH, T, and TV. In this study, weighted-means values demonstrated mTESE to be superior to cTESE with an SRR of 51.9% vs 40.1%. Multiple weighted linear regressions were created to describe associations among SRR, procedure type, FSH, T, and TV. The models showed that for every 1.19 mIU ml-1 increase in FSH, there would be a significant decrease in SRR by 1.0%. Seeking to create a more clinically relevant model, FSH values were then divided into normal, moderate elevation, and significant elevation categories (FSH <10 mIU ml-1, 10-19 mIU ml-1, and >20 mIU ml-1, respectively). For an index patient undergoing cTESE, the retrieval rates would be 57.1%, 44.3%, and 31.2% for values normal, moderately elevated, and significantly elevated, respectively. In conclusion, in a large meta-analysis, mTESE was shown to be more successful than cTESE for sperm retrievals. FSH has an inverse relationship to SRR in retrieval techniques and can alone be predictive of cTESE SRR.

The hemodynamic characteristics of venous reflux are associated with infertility in patients with varicocele; however, an effective method for quantifying the structural distribution of the reflux is lacking. This study aimed to predict surgical outcomes using a new software for venous reflux quantification. This was a retrospective cohort study of a consecutive series of 105 patients (age range: 22-44 years) between July 2017 and September 2019. Venous reflux of the varicocele was obtained using the Valsalva maneuver during scrotal Doppler ultrasonography before microsurgical varicocelectomy. Using this software, the colored reflux signals were segmented, and the gray scale of the color pixels representing the reflux velocity was comprehensively quantified into the mean reflux velocity of the green layer (MRVG) and the reflux velocity standard deviation of the green layer (RVSDG). Spontaneous pregnancy and changes from baseline in the semen parameters were assessed during a 12-month follow-up period. Data were analyzed using logistic regression analysis. An association of the high MRVG group with impaired progressive motility (odds ratio [OR] = 2.868, 95% confidence interval [CI]: 1.133-7.265) and impaired sperm concentration (OR = 2.943, 95% CI: 1.196-7.239) was found during multivariate analysis. High MRVG (OR = 2.680, 95% CI: 1.086-6.614) and high RVSDG (OR = 2.508, 95% CI: 1.030-6.111) were found to be independent predictors of failure to achieve pregnancy following microsurgical repair. In summary, intense venous reflux is an independent predictor of impaired progressive motility, sperm concentration, and pregnancy outcomes after microsurgical varicocelectomy.

Seminal duct obstruction may result in obstructive azoospermia (OA) and severe oligoasthenoteratozoospermia (OAT) (<0.5 million/mL) (Nordhoff et al., 2015). Cases of partial OA and OAT can be treated effectively by microsurgical anastomosis (Goldstein and Kim, 2013) to obtain successful surgical reversal. However, microsurgical vasovasostomy (VV) (Dickey et al., 2015) and vasoepididymostomy (VE) (Peng et al., 2017) are not suitable for patients with atypical OA and poor epididymis conditions or unpredictable obstruction of the distal vas deferens. For those patients, cross anastomosis may be applied instead of routine VE or VV. A single-center, retrospective, comparison study was conducted, which assessed the usefulness of the cross VV (CVV) in the scrotum for indication and efficacy. A total of 77 cases with OA or OAT were included, and 20 cases implemented cross anastomosis, including unilateral CVV (UCVV) in 4 cases, unilateral VE plus CVV (UVE+CVV) in 11 cases, and unilateral VV-based CVV (UVV+CVV) in 5 cases. The other 57 cases received no cross-matching anastomosis. The patency and natural pregnancy rates in one year were 75.0% and 50.0%, respectively, in the UCVV group; 54.5% and 27.3%, respectively, in the UVE+CVV group; and 60.0% and 40.0%, respectively, in the UVV+CVV group. The CVV in the scrotum in the selected patients with OA and severe OAT could yield good results. We regard the CVV in the scrotum as an efficacious operation with a lower risk of injury in cases of atypical OA.

This study was performed to evaluate the oncological and reproductive outcomes of childbearing-age women treated with fertility-sparing surgery (FSS) for non-epithelial ovarian tumors in China. One hundred and forty eight non-epithelial ovarian tumor women treated with FSS between January 1, 2000 and August 31, 2015 from two medical centers in China were identified. Progression-free survival (PFS) was 88.5%, whereas overall survival (OS) was 93.9%. Univariate analysis suggested that delivery after treatment is related to PFS (P = 0.023), whereas histology significantly influenced OS. Cox regression analysis suggested that only histology was associated with PFS and OS (P < 0.05). Among the 129 women who completed adjuvant chemotherapy (ACT), none developed amenorrhea. Among the 44 women who desired pregnancy, 35 (79.5%) successfully had 51 gestations including 35 live births without birth defects. Non-epithelial ovarian tumors can achieve fulfilling prognosis after FSS and chemotherapy. Histology might be the only independent prognostic factor for PFS and OS. FSS followed by ACT appeared to have little or no effect on fertility. Meanwhile, postoperative pregnancy did not increase the PFS or OS. Use of gonadotropin-releasing hormone agonist was not beneficial for fertility.

Objective:
To investigate the success rate and safety of percutaneous vasoseminal vesiculography with the disposable vasographic interventional therapy kit (VITK).
METHODS:
This study included ninety-six 19-65 (mean 43) years old male patients with infertility, hematospermia, seminal vesicle cyst, ejaculatory duct cyst, ejaculatory dysfunction, or vas deferens injury, with disease courses varying from 1 month to 7 years. With an open, multi-centered, single-group, self-controlled design and using the disposable VITK, we treated the patients by percutaneous vasoseminal vesiculography via injection of contrast medium into the vas deferens cavity under local anesthesia.
RESULTS:
Percutaneous vasoseminal vesiculography was successfully performed in 92 (97.87%) of the patients, which revealed abnormal seminal ducts in 51 cases (54.3%). Among the 28 infertile patients, 3 were found with bilateral and 5 with unilateral vas deferens obstruction. Vesiculitis was detected in 36 (81.8%) of the 44 hematospermia patients and bilateral vas deferens abnormality in 5 (38.5%) of the 13 patients with ejaculatory dysfunction. Transectional damage was observed in 2 patients with vas deferens injury induced by bilateral inguinal hernia repair. Three cases of seminal vesicle cyst and 4 cases of ejaculatory cyst were definitely diagnosed by vasoseminal vesiculography.
CONCLUSIONS
The disposable vasographic interventional therapy kit, with the advantages of simple operation and high safety, deserves a wide clinical application in vasoseminal vesiculography.

National Journal of Andrology 2018;24(7):579-288
In the past two decades, with the rapid development of assisted reproductive technology and particularly the technological advances in male infertility microsurgery, many obstructive azoospermia-related infertile couples can now acquire the chances of natural pregnancy via reconstruction of the seminal tract. This article highlights the latest advances in surgical reconstruction of the seminal tract for the treatment of obstructive azoospermia, such as the application of laparoscopic and robotic techniques, with a discussion on microsurgical epididymal sperm aspiration and preservation, potential use of absorbable sutures or the bio-suture tape for microsurgical anastomosis in the management of obstructive azoospermia.

We report the largest single-center experience with robotic-assisted microscopic varicocelectomy (RAMV) in male infertility. From August 2012 to February 2015, men with infertility of at least a year and varicoceles underwent RAMV by a single surgeon. Varicocele was diagnosed on physical examination and confirmed by ultrasound by a single ultrasonographer. Preoperative hormone panel, semen analyses, and testicular Doppler ultrasound were obtained from all men and repeated at 3 months. One hundred and forty consecutive men (258 varicocelectomies) were included. Mean age and duration of infertility was 36.4 and 2.8 years, respectively. Median total and free testosterone increased by 145 ng dl-1 and 4.3 pcg ml-1 (44.3%), respectively (P < 0.0001). Median sperm concentration increased by 37.3% (P < 0.03). Median sperm motility and morphology did not significantly change. Median left and right testicular volume increased by 22.3% (P < 0.0001) and 12.6% (P < 0.0006), respectively. Hydroceles occurred 0.8% of procedures. We had no testicular artery injuries. Persistence of varicocele by Doppler ultrasound was 9.6%. Only 37.3% of patients required pain medications postoperatively. We concluded that RAMV is a safe and effective alternative for varicocele repair with outcomes comparable to historical traditional microsurgical approach.

This study was performed to investigate a potential marker for the presence of spermatozoa in the ejaculate following varicocelectomy in Chinese men with nonobstructive azoospermia and varicoceles. The micro-RNA (miR)-192a levels in seminal plasma and testicular tissue were evaluated by quantitative real-time polymerase chain reaction from 60 men with nonobstructive azoospermia and varicoceles (Group A: 27 men with spermatozoa found in the ejaculate after surgery; Group B: 33 men without spermatozoa found in the ejaculate after surgery) and 30 controls. The seminal plasma and testicular tissue miR-192a levels were higher in Group B than in Group A and the controls (P < 0.001), and there was no significant difference between Group A and the controls (P > 0.05). Apoptosis and proliferation assays with miR mimics and inhibitors showed that miR-192a induced GC-2 cell apoptosis through the activation of Caspase-3 protein. Thus, seminal plasma miR-192a appears to be a potential marker for successfully indicating spermatozoa in the ejaculate following microsurgical varicocelectomy in men with nonobstructive azoospermia and varicoceles. Seminal plasma miR-192a may be a useful clinical marker for prescreening to determine which patients with nonobstructive azoospermia and varicoceles would benefit from varicocelectomy.
