Previous studies have reported the prognostic value of neutrophil/lymphocyte ratio (NLR), platelet/lymphocyte ratio (PLR), lymphocyte/monocyte ratio (LMR), and systemic immune-inflammation index (SII). However, the prognostic performance of these indices in patients with testicular lymphoma has not yet been studied. This study was to systematically evaluate the role of NLR, PLR, LMR, and SII in predicting survival for patients with testicular diffuse large B-cell lymphoma. In this study, 28 patients with testicular diffuse large B-cell lymphoma were enrolled. We performed univariate and multivariate analyses to assess associations of indices incorporating blood cell counts with progression-free survival (PFS) and overall survival (OS). The results of univariate analysis revealed that International Prognostic Index (IPI) score ( = 0.010, = 0.034, respectively), NLR ( = 0.003, = 0.025, respectively), and LMR ( = 0.004, = 0.010, respectively) were significantly associated with PFS and OS. Lactic dehydrogenase (LDH) ( = 0.017), absolute neutrophil counts ( = 0.018), absolute monocyte counts ( = 0.001), and SII ( = 0.005) were significantly associated with the risk of disease progression, while ECOG performance status ( = 0.016) was shown to be related to the risk of death. In the multivariate analysis, NLR (HR 9.069, = 0.001) and absolute monocyte counts (HR 37.076, = 0.001) were shown to be independently associated with risk for disease progression, while LMR (HR 0.077, = 0.028), and ECOG performance status (HR 20.013, = 0.026) were proved to be independent predictors of OS. In conclusion, high absolute monocyte counts, high NLR and low LMR may indicate unfavorable prognosis in testicular diffuse large B-cell lymphoma patients. Since indices incorporating blood cell counts are low cost parameters, they may provide additional prognostic value beyond standard clinicopathological parameters. However, further studies are needed to confirm our findings.

From biological marker to clinical application: the role of anti-Müllerian hormone (AMH) for delayed puberty and idiopathic non-obstructive azoospermia in males.

Anti-Müllerian hormone (AMH), a biomarker secreted by Sertoli cells in the testes, has emerged as a critical indicator of male reproductive function with significant clinical application potential. AMH reflects Sertoli cell activity and plays a pivotal role across different stages of male gonadal function. Firstly, in prepubertal males, AMH levels are crucial for assessing testicular development and the progression of puberty, with delayed or insufficient AMH secretion often being associated with disorders like delayed puberty.

The treatment of chronic testicular pain is a complex condition that will be encountered by most practicing clinicians. In this study, the influence of low-level laser irradiation of the red and infrared spectral range for treating chronic testicular pain was evaluated and compared. In this double-blind, placebo-controlled randomized clinical trial study, 60 patients were randomly divided into three groups of 20: (1) low-level laser group with red (650 nm, 50 mW), (2) low-level laser group with infrared (820 nm, 100 mW) and (3) laser placebo group.

Introduction: Vital dyes lymphography during laparoscopic varicocelectomy (LV) has been suggested to allow for lymphatic mapping thereby allowing for lymphatic sparing (LS) and subsequent reduction of hydrocele formation. Intratesticular injection of the dye seems to achieve the best lymphatic visualization, however, the potential toxicity of some agents, is a cause of concern for the risk of testicular pathological changes. We report our experience with LV, to test the hypothesis that Intraoperative lymphography with methylene blue (BL), is safe and reduces the rate of post-operative hydrocelectomy.

Introduction: Laparoscopic Fowler Stephens orchidopexy, single stage or two-stage, is now routinely performed in non-palpable testis. We performed second stage orchidopexy as open inguinal approach and compared the outcome of this approach to two-staged laparoscopic orchidopexy.
Methods: We performed a prospective randomized interventional study of two different approaches for intra-abdominal testis.

: Salvage treatment options have not been validated in relapsed or refractory germ cell tumors. Moreover, the study populations including these patients have different heterogeneities. This study aimed to evaluate the efficacy and safety of three cycles of TIP sequential high-dose chemotherapy in patients with testicular non-seminomatous germ cell tumors who relapsed or had a refractory course after first-line platinum-based chemotherapy.
