Welcome @harolddr, I have not heard that statins do nothing for women but help only middle-age men. I chose not to take them but to instead work on lowering the numbers with lifestyle changes. My decision was based on studies showing statins can induce neuropathy. Here are a couple of references on your question:

-- Women Versus Men: Is There Equal Benefit and Safety from Statins?: https://pubmed.ncbi.nlm.nih.gov/26782824/
-- "Specifically, for every decrease of 40 mg/dl of LDL (bad cholesterol) when on treatment with a statin, the risk of major cardiovascular events was decreased by 16 percent in women and by 22 percent in men, which did not represent a statistically significant difference between the benefits in men and women." -- Efficacy and safety of LDL-lowering therapy among men and women: meta-analysis of individual data from 174 000 participants in 27 randomised trials: https://www.sciencedirect.com/science/article/abs/pii/S0140673614613684

Have you discussed alternatives like lifestyle changes and diet vs taking statins with your doctor?
