Abstract

Structured Abstract Objective This study aims to investigate the impacts of alcohol on blood-testis barrier integrity using a novel in vitro model and to elucidate potential non-hormonal mechanisms underlying alcohologenic reversible azoospermia. Design Primary rhesus macaque Sertoli cells were exposed to ethanol to evaluate dose-dependent effects on BTB integrity. Barrier function was assessed through electrical resistance and permeability assays, with recovery evaluated after a 48-hour withdrawal period. Gene expression of Sertoli cell and tight junction markers and cytokine levels associated with barrier degradation were analyzed. Subjects Primary rhesus macaque Sertoli cells were used. Exposure Clinically relevant concentrations (10, 60, and 100 mM), equivalent to 1-2 drinks to requiring hospitalization, of ethanol were used. Main Outcome Measures The main outcome measures were BTB integrity and permeability, assessed via transepithelial electrical resistance and Dye Flux assays, recovery of barrier function after ethanol withdrawal, gene expression changes in Sertoli cell and tight junction markers, and cytokine levels associated with barrier impairment. These metrics evaluated the functional and molecular impacts of in vitro ethanol exposure on the BTB. Results Ethanol exposure was associated with a dose-dependent decrease in BTB integrity, with partial recovery observed at lower concentrations (10 and 60 mM) after 48 hours of withdrawal, but not at 100 mM.…
