Abstract
Purpose: We investigated the correlations of serum total testosterone (TT) levels with body composition and physical fitness
parameters in patients with erectile dysfunction (ED) to know the best exercise for testosterone deficiency.
Materials and Methods: Eighty-seven ED patients underwent serum TT assessment as well as body composition and basic
exercise testing. The bioelectrical impedance analysis was used to assess body composition. Seven types of basic exercise
tests were used to determine physical fitness. Correlations between serum TT levels and body composition/physical function
parameters were evaluated using partial correlation analyses. A serum TT cut-off value was obtained for the parameters significantly
correlated with serum TT levels.
Results: The subjects had a mean serum TT level of 342.1 ng/dL. Among the body composition parameters, body and abdominal
fat percentages showed statistically significant negative correlations with serum TT levels. Among the basic exercise
test parameters, only the cycle ergometer test for cardiorespiratory fitness showed a statistically significant positive correlation
with serum TT levels.
Conclusions: Serum TT levels in patients with ED, may be increased by reducing fat percentage and improving cardiorespiratory
fitness via aerobic exercise
