ALB and benign prostatic hyperplasia: Notably, elevated exposure to albumin, isoleucine, esters in medium HDL, cholesterol to total lipids ratio in medium LDL, phospholipids to total lipids ratio in small VLDL, and total concentration of branched-chain amino acids (leucine + isoleucine + valine) escalates the risk of BPH, thereby underscoring their potential as pathogenic factors for BPH.
