Summary In an attempt to determine whether the androgen profiles of the prostate fluid (EPS) mirror the concentrations in the prostate tissue, we have measured testosterone and dihydrotestosterone (DHT) in EPS and correlated their levels to the concentrations found in hyperplastic prostate tissue (BPH) obtained from the same 19 patients. Although androgen concentrations in EPS were very high (testosterone=106.7±81.9 ng/g dry weight; DHT=54.2±11.2 ng/g dry weight), they did not reflect the concentrations measured in BPH tissue (testosterone=7.56±1.54 ng/g dry weight; DHT=10.54±0.63 ng/g dry weight). Additionally the accumulation of tissular DHT usually associated with BPH was not mirrored in the EPS specimens which demonstrated a relatively higher concentration of testosterone when compared to DHT. In EPS, there was also a very strong correlation between testosterone and DHT concentrations (r=0.89; P〈0.01). We have also measured zinc concentrations in EPS and BPH tissue but were unable to detect any relationship between the two parameters. Significantly, however, EPS zinc concentrations showed a close correlation with EPS testosterone (r=0.73; P〈0.01) and DHT (r=0.69; P〈0.01) concentrations.
