ER, estrogen receptors; LUTS, lower urinary tract symptoms; PSA, prostate-specific antigen; E, serum estradiol; T, serum total testosterone; E/T, serum estradiol/total testosterone ratio; PVR, postvoid residual volume; PS, prostate size; Q_max, maximal flow rate; IPSS, International Prostate Symptom Score; SERα, stromal estrogen receptor alpha level; EERα, epithelial estrogen receptor alpha level; EERβ, epithelial estrogen beta level.

A p-value <0.05 was considered statistically significant.
