โฆ Synopsis
A morphometric analysis was performed to obtain quantitative data on age-related changes in prostatic endocrine cell (PrEC) density. Sixty prostates from subjects aged 14-74 years were studied with a semi-automatic image analysis system (ASM 68K, Leitz) applied to sections immunostained for chromogranin A-reactive cells. The highest density of PrECs (0.366 cells/mm of epithelial length) was found in the 25-54 year age group, which was significantly different from that found in prostates of the younger (0.311 cells/ mm) and the older (0.261 cells/ram) age groups. The data probably reflect the higher incidence of incompletely developed glandular units in the younger group and the formation of new alveoli related to the usual glandular hyperplasia that occurs with increasing age in the older group.

## BACKGROUND. It is well-known that the incidence of benign prostatic hyperplasia (BPH) increases with aging. The age-dependent changes in the ratio of serum sex steroid concentrations may play a role in BPH development. To clarify the relationship between the prostatic tissue concentrations of th
