Fig. 4. Significant correlation between various measures of benign prostatic hyperplasia (BPH) and estrogen receptor (ER) in prostatic stroma and epithelium. (A) ER alpha (ERα) in stroma vs. age (r=0.37). (B) ERα in stroma vs. prostate-specific antigen (PSA) (r=0.32). (C) ERα in epithelium vs. International Prostate Symptom Score (IPSS) (r=0.32). (D) ERα in epithelium vs. prostate size (r=0.38). (E) ERα in stroma vs. prostate size (r=0.51). (F) ERα in epithelium vs. serum estradiol (r=0.53). (G) ER beta (ERβ) in epithelium vs. serum estradiol (r=0.56). A p-value of <0.05 was considered statistically significant.
