Abstract:
Sex hormones have substantial effects on crystal formation in the rat kidney through oxalate metabolism and oxidative cell damage. Testosterone is a promoter and estradiol an inhibitor of such crystal formation. The development of new medications related to sex hormones or GO are anticipated for sufferers of recurrent urolithiasis.
