AbstractBackgroundA recent meta‐analysis (Human Reproduction Update 23, 2017 and 265) reported positive sperm retrieval rates (SRR) in 50% of patients with Klinefelter syndrome (KS) undergoing testicular sperm extraction (TESE). However, these results do not reflect the rates of SR that we observe in clinical practice. We assessed the rate and potential predictors of SR in Klinefelter patients in the real‐life setting.Materials and MethodsWe reviewed clinical data of 103 KS men who underwent TESE between 08/2008 and 03/2019 at five tertiary referral Andrology centers. Patients underwent testis ultrasound, hormonal evaluation, and genetic testing. All patients were azoospermic based on the 2010 WHO reference criteria. Conventional TESE (cTESE) or microsurgical TESE (mTESE) was performed based on the surgeon's preference. We used descriptive statistics and logistic regression models to describe the whole cohort.ResultsMedian (IQR) patient's age was 32 (24‐37) years. Baseline serum FSH and total testosterone levels were 29.5 (19.9‐40.9) mUI/mL and 3.8 (2.5‐11.0) ng/mL, respectively. Conventional TESE and mTESE were performed in 38 (36.5%) and 65 (63.5%) men, respectively. The sperm retrieval rate was 21.4% (22/103 men). Fifteen patients used spermatozoa for ICSI and five ended in live birth children. Patients with positive SR were similar to those with a negative TESE in terms of clinical, hormonal, and procedural parameters (all P > .05). Logistic regression analyses confirmed the lack of association between clinical, hormonal, and procedural parameters with SR outcome.DiscussionGiven the conflicting results in the literature regarding SRR in KS, patients should be carefully counseled regarding TESE outcomes based on data from published literature and local results.ConclusionsIn the real‐life setting, we observed a lower SRR (21.4%) than that reported in meta‐analyses in our cohort of KS patients. No associations between clinical, hormonal, and procedural variables with TESE success were found.

Objective To assess the impact of primary or progressive status on recurrence‐free survival ( RFS ), cancer‐specific mortality ( CSM ) and overall mortality ( OM ) after radical cystectomy ( RC ) for muscle‐ invasive bladder cancer ( MIBC ). Patients and Methods A total of 768 consecutive patients underwent RC as treatment for MIBC at our institution between 2000 and 2012. Primary MIBC was defined as no previous history of bladder cancer and progressive was defined as recorded previous treated non‐ MIBC ( NMIBC ) that had progressed to MIBC . The median follow‐up was 85 (60–109) months. Univariate and multivariate Cox regression models were used to compare RFS , CSM and OM between these two cohorts. Results In all, 475 (61.8%) patients had primary and 293 (38.2%) patients had progressive MIBC . There were no differences between the two groups in terms of demographics, pathological and peri‐operative complications (all P > 0.1). The 10‐year RFS , CSM and OM rates for primary vs progressive status were 43 vs 36% ( P = 0.01), 43 vs 37% ( P = 0.01), and 35 vs 28% ( P = 0.03), respectively. On multivariable Cox regression analyses, progressive status remained significantly associated with a higher rate of recurrence (hazard ratio [ HR ] 1.47, 95% confidence interval [ CI ] 1.12–1.79; P = 0.03), CSM ( HR 1.42, 95% CI 1.07–1.89; P = 0.01) and OM ( HR 1.42, 95% CI 1.13–1.65; P = 0.02). Conclusions Among patients treated with RC for MIBC , progressive status was associated with a higher CSM , OM and recurrence rate after RC . The present study thus provides an impetus to improve risk sub‐stratification when bladder cancer is still at the NMIBC stage, be it through new biomarkers or improved imaging, as a subset of patients with NMIBC are likely to benefit from early RC .
