RASB was associated with lower levels of serum testosterone in men <60 years old ( P = 0.02), but had no effect on serum testosterone levels in older men or women. Multiple regression analysis demonstrated that serum testosterone negatively correlated with Epo dose ( P = 0.045) when all groups of patients were considered together.
