The study involved over 1000 men and women with high LDL cholesterol levels. These individuals were assigned to take either a statin (simvastatin or pravastatin) or a placebo. The investigators found that along with lowered LDL levels, those individuals taking statins also saw a decrease in sexual pleasure. Men appeared to be affected more than women during the study.
The effect of statins on sexual function is not fully known. While there have been other studies that have suggested that statins could improve sexual function, this study contradicts it. The investigators of this study are not sure if it is the statins themselves that are affecting sexual function, or if it is the large decrease in LDL that is causing it.
