[Correlation of aging with psychological and organic ED: nocturnal electrobioimpedance volumetric assessment of 83 cases].
OBJECTIVE
The ratio of psychological to organic ED changes with aging. This study aimed to analyze the results of nocturnal electrobioimpedance volumetric assessment (NEVA) for ED patients of different age groups and their significance in the diagnosis of ED.


METHODS
A total of 83 ED patients were divided into 4 age groups (< or = 29 yr, 30 -39 yr, 40 -49 yr and > or = 50 yr) and detected for nocturnal penile tumescence (NPT) by NEVA.


RESULTS
Thirty-four of the cases were diagnosed as organic ED, and the other 49 as psychological ED. With the increase of age, the former was increased from 30.3% in the < or = 29 yr group to 60.0% in the > or = 50 yr group, while the latter decreased from 69.7% to 40.0%.


CONCLUSIONS
The percentage of organic ED tends to grow with the increase of age, while that of psychological ED is just the opposite.
