ABSTRACT
The purpose of this study was to evaluate the effect of bicycle saddle shape on penile blood flow during cycling. Penile blood flow was measured using a laser Doppler flowmeter in 20 potent male volunteers. In a counterbalanced, crossover design, measurements were taken in the standing and sitting positions, on either a narrow unpadded or wide unpadded saddle, before and after cycling for 5 min. Before cycling, penile blood flow (ml/min/100 g tissue) was significantly decreased from 1.6+/-0.7 to 1.5+/-0.7 (P=0.010) on the wide saddle and from 1.7+/-0.6 to 1.0+/-0.5 (P<0.001) on the narrow saddle. After 5 min of cycling, the changes in penile blood flow on the wide and narrow saddles were 0.34+/-0.49 and -0.38+/-0.49, respectively (P<0.001). The narrow saddle is associated with more significant reductions in penile blood flow and could be a source of blunt perineal trauma, potentially leading to erectile dysfunction.
