Abstract: In the male body, zinc accumulates most abundantly in prostatic cells, where it plays a key role in producing high amounts of citrate in seminal fluid. Intraprostatic accumulation of Zn increases during the development of benign prostatic hyperplasia (BPH), one of the most common diseases in men over 50 years of age. Continuing our investigations on intraprostatic androgens, in this study, we analyzed the mineral content (Zn, Ca, Cu, K, Mg, Mn, and Na) in the transitional zone (TZ) of the prostate using inductively coupled plasma optical emission spectrometry (ICP-OES). The concentrations of testosterone (T) and dihydrotestosterone (DHT) were determined by liquid chromatography-mass spectrometry (LC-MS). Group-wise and correlation analyses demonstrated a descriptive trend toward a volume-dependent increase in Zn concentrations within TZ tissue, whereas other elements exhibited heterogeneous covariance patterns; intraprostatic hormone levels, although elevated in larger prostates, showed no consistent linear correlations with elemental concentrations. Given the observational design of the present study, the reported tissue Zn profiles cannot be interpreted as evidence supporting supplementation in BPH, and any potential clinical implications warrant evaluation in rigorously designed interventional studies.
