Staging and cell detection of seminiferous tubules using neural networks [PDF]
Spermatogenesis is a complex differentiation process that takes place in the seminiferous tubules. A specific organization of spermatogenic cells within the seminiferous epithelium enables a synchronous progress of germ cells at certain steps of ...

Cell Proliferation, EarlyView.In hyperuricemia, uric acid inhibits CCDC90B ubiquitination degradation by binding to it. Excessive CCDC90B induces mitochondrial calcium overload, leading to mitochondrial quality control imbalance and ultimately resulting in SLC senescence and decreased testosterone levels.

Cell Proliferation, EarlyView.Wt1 expressed in the MD mesenchyme promotes MD regression by inducing Wif1 and Osx transcription. In male mice, mesenchyme‐specific inactivation of Wt1 results in MD retention. ABSTRACT In mammals, Müllerian ducts (MDs) are the precursors of the female reproductive tract which regress in males during embryonic development.

Quantitative Analysis of the Cellular Composition in Seminiferous Tubules in Normal and Genetically Modified Infertile Mice [PDF]
The aim of this study was to establish a quantitative standard for the cellular composition in seminiferous tubules at each stage of spermatogenesis in the mouse testis, and thereby evaluate abnormalities in the infertile mouse testis.

Testicular torsion in foals and stallions
Equine Veterinary Education, EarlyView.Summary Testicular torsion is a rare condition in horses characterised by a change in the position of the testis due to the testicular mesentery twisting around its own axis; it can occur both when the testis is still in the abdominal cavity and when it has descended into the scrotum.

Humanin ameliorates diabetes‐induced testicular damage in a streptozotocin‐induced mouse model
Experimental Physiology, EarlyView.Abstract Diabetes mellitus is a major metabolic disorder closely associated with oxidative stress and male reproductive dysfunction. Humanin, a mitochondria‐derived peptide, has been reported to exert cytoprotective, anti‐apoptotic and antioxidant effects in various disease models; however, its role in diabetes‐induced testicular damage remains unclear.

Morfometrical analysis of diameters of leydig cells nuclei and seminiferous tubules at cryptorchid testes of young males [PDF]
, 2009 Leydigove stanice smještene su u intersticijskom tkivu testisa između sjemenskih kanalića. Istraživanje je obuhvatilo biopsije kriptorhičnih testisa petnaestorice muškaraca (18 do 27 god). Kao kontrola poslužili su uzorci tkiva testisa dvojice muškaraca (

Clinical Pharmacology &Therapeutics, Volume 120, Issue 2, Page 501-509, August 2026.Pretomanid is a component of the World Health Organization‐recommended treatment regimen for drug‐resistant tuberculosis in patients aged ≥ 14 years. While preclinical rodent studies identified testicular toxicity as a potential clinical liability at elevated doses, no corresponding effects were observed in nonhuman primates nor clinical hormone ...

Morphological alterations in the seminiferous tubules of adult Wistar rats: the effects of prenatal ethanol exposure [PDF]
, 2004 This study presents the effects of prenatal ethanol exposure on the morphology of the seminiferous tubules of the testes in the adult male rat. Timed-pregnant adult female Wistar rats (average weight 200 g) were given daily intragastric intubation of 5.8
