Does atorvastatin affect androgen levels in men in the era of very-low LDL targeting therapy?
BACKGROUND
An adequate pool of free intracellular cholesterol is essential for steroidogenesis in gonads and LDL is the major source of cholesterol used in this pathway. Effect of peripheral LDL on the synthesis of steroids is dose dependent and although LDL levels around 100 mg/dl is demonstrated to be safe in terms of steroidogenesis, effect of LDL levels <70 mg/dl with higher doses of statins on steroidogenesis remains controversial.


METHODS
Androgen and gonadotropin levels are prospectively evaluated at baseline and after 12 weeks of treatment in 77 male coronary heart disease patients receiving high doses of atorvastatin (40-80 mg daily) targeting serum LDL levels <70 mg/dl and in 83 male coronary heart disease patients receiving regular doses of atorvastatin (10-20 mg daily) targeting serum LDL levels <100 mg/dl.


RESULTS
At the end of the study, mean LDL levels of the high and regular dose atorvastatin groups were 77+/-9 mg/dl and 98+/-10 mg/dl respectively. After twelve weeks of treatment, there were no significant alterations in serum total testosterone, free testosterone, sex hormone binding globulin, luteinizing hormone and follicle stimulating hormone levels between two groups.


CONCLUSIONS
High dose atorvastatin in order to reach serum LDL levels around 70 mg/dl seems to be as safe as regular doses in order to reach serum LDL levels around 100 mg/dl, in terms of gonadal steroidogenesis in men with coronary heart disease.
