Association between anti-Müllerian hormone concentrations and sperm retrieval outcomes in patients with idiopathic nonobstructive azoospermia: a systematic review and meta-analysis.
Microdissection testicular sperm extraction (mTESE) is commonly performed to retrieve sperm in the testes for assisted reproductive techniques in patients with idiopathic nonobstructive azoospermia (iNOA). However, the success rate of sperm retrieval varies among individuals. We aim to investigate the association between clinical parameters and sperm retrieval outcomes in patients with iNOA. We searched PubMed, EMBASE, and Web of Science from database inception to August 2, 2023. The main measure was whether sperm retrieval was successful in patients with iNOA who underwent mTESE. Pooled estimates of the sperm retrieval rate and weighted mean differences were calculated using random-effects models. The overall sperm retrieval rate was 36.8% (95% confidence interval [CI]: 27.5%-46.0%, I2 = 95.0%) in nine studies comprising 1892 patients with iNOA. No significant differences were found in age, testicular volume, serum total testosterone concentrations, or inhibin B concentrations between positive and negative sperm retrieval outcomes. Lower anti-Müllerian hormone concentrations in patients with iNOA were associated with a positive outcome of mTESE (weighted mean differences: -2.70; 95% CI: -3.94--1.46, I2 = 79.0%). In conclusion, this study shows a significant relationship between anti-Müllerian hormone and sperm retrieval outcomes in patients with iNOA, while age, testicular volume, total testosterone, and inhibin B show no significant association. These findings have important implications for assessing the potential success of sperm retrieval and selecting appropriate treatment strategies in patients with iNOA.

BACKGROUND
Laparoscopic exploration is currently considered the gold standard for managing nonpalpable intraabdominal testes. The problem of short vascular pedicle is addressed in Fowler-Stephen (FS) technique by the division of testicular vessels and in Shehata technique (ST) by traction on testicular vessels. There is a lack of the consensus among pediatric surgeons on the choice of one technique over other. This analysis compares the reported outcomes of staged laparoscopic orchidopexy by ST with the time tested FS technique in managing high intraabdominal undescended testis.
MATERIALS AND METHODS
The present systematic review and meta-analysis was conducted as per the preferred reporting items for the systematic review and meta-analyses guidelines. Only randomized controlled trials and comparative studies were included. The primary outcomes compared were the incidence of testicular atrophy, testicular retraction/ascent rate, and operative time of Stage I and Stage II orchidopexy.
RESULTS
The present analysis was based on three randomized studies with a total of 119 undescended testes in 117 patients satisfying the inclusion criteria. The operative time was less in Stage I FS technique; however, there was no statistically significant difference in operative time of both procedures during the Stage II laparoscopic orchidopexy. Pooled analysis of postintervention testicular atrophy, testicular retraction rate, and duration of postoperative hospitalization showed no difference between both procedures.
CONCLUSION
Both FS and STs are comparable in terms of postintervention testicular atrophy, testicular retraction/ascent; however, the mean operative time is significantly less with FS technique in Stage I laparoscopic orchidopexy.

Meta-Analysis
INTRODUCTION
The COVID-19 can affect human testicles, thus will interfere the production of important male sexual hormone such as testosterone. Our study provides scientific evidence through systematic reviews and meta-analyses that focus on the effects of SARS-CoV-2 virus infection on male sexual hormonal disorders in patients post-exposure to COVID-19.
METHODS
This meta-analysis was made in accordance with the PRISMA guidelines. The outcomes of this study were the level of total testosterone, free testosterone, LH and FSH. Chi-square and I2 tests were used to evaluate heterogeneity between studies. The standardized mean deviation (SMD) with 95% CI were used and analysis was performed using the Review Manager 5.4 software.
RESULTS
The four included studies reported a total of 256 patients with COVID-19 with time of follow-up time post COVID-19 varying from one month to 7 months. The mean age distribution in the study was 34-57 years old. Total testosterone level (SMD = -158.71; 95% CI= -205.30 - -112.12; p<0.00001) was significantly higher at follow-up post COVID-19, while LH (SMD = 0.40; 95% CI = 0.15-0.65; p=0.002) was lower. The free testosterone level and FSH level showed no significant difference between baseline and after following up post COVID-19.
CONCLUSIONS
At follow up, the total testosterone level in patients with SARS-CoV-2 infection appeared to be elevated while LH was lower compared to the baseline.
