Zhou and colleagues explore reversing testicular aging and late-onset hypogonadism by targeting lysosomal function in Sertoli cells. The aging-related transformation of Sertoli cells into a lipid-hoarding subtype with dysregulated phagolysosomes and autolysosomes was reversed using the TRPML channel agonist ML-SA1, which demonstrates the potential of this targeted therapy in alleviating testosterone decline and systemic male-aging phenotypes.
