Testes size, testosterone production and reproductive behaviour in a natural mammalian mating system [PDF]
, 2012 1. Testosterone (T) is a key mediator in the expression of numerous morphological and behavioural traits in mammals, but the factors underlying individual variation in circulating T levels are poorly understood. 2.

Super-Multiplexed Label-Free Raman Imaging Uncovers Novel Testicular Metabolic Couplings for Residual Body and Spermatogonial Differentiation. [PDF]
Adv Sci (Weinh)Super‐multiplexed Label‐free Raman Imaging (SLRI) enables 2D/3D metabolic mapping of intact Drosophila testes. Moving beyond descriptive morphology, it establishes a multidimensional tool for tissue metabolic remodeling, and offers a generalizable platform for complex tissue analysis, with implications extending to development and disease. ABSTRACT The

WFS1 Deficiency Impairs PIAS4-Associated SUMOylation and Increases Ubiquitin-Mediated Spermatogenesis-Related Protein Degradation Leading to Testicular Male Infertility. [PDF]
Adv Sci (Weinh)The findings establish a critical role for WFS1 in human male fertility. Mechanistically, WFS1 interacts with PIAS4 to promote the SUMOylation of key spermatogenesis‐associated proteins, which in turn competitively inhibits their K48‐linked ubiquitin‐mediated degradation during spermatogenesis.

BOULE is Essential for the Dynamic Disassembly of Heat Shock Granules in Male Germ Cells. [PDF]
Adv Sci (Weinh)BOULE orchestrates stress granule disassembly in germ cells via a two‐pronged mechanism: it promotes G3BP1 ubiquitination by upregulating TRIM27, generating a signal for VCP/FAF2 recruitment, and it maintains G3BP1 and FAF2 protein levels. BOULE deficiency disrupts disassembly complex formation, leading to impaired heat shock granule clearance ...

Prenatal and Postnatal Exposure to Cell Phone Radiation and its Possible Impact on the Development of Albino Rat Testicular Tissue Light and Electron Microscopic Study [PDF]
The Egyptian Journal of Histology, 2022 Introduction: Perinatal periods are critical phases in the development of testis, and it is sentient to the surrounding environmental pollutants. Electromagnetic radiation (EMR) exposure as a consequence of excessive use of cell phones might be one of ...
