The study's first author Dr. Steven Schrader, an expert associated with the National Institute for Occupational Safety and Health in Cincinnati, has revealed that the study involved 90 police officers from five metropolitan regions in the U.S.
The participants using traditional saddles were evaluated prior to changing saddles, and then again after six months of using the noseless bicycle saddle.
The researchers found that the noseless saddle resulted in a reduction in saddle contact pressure in the perineal region, and that there was a significant improvement in penile tactile sensation.
They also found that the number of men indicating they had not experienced genital numbness while cycling for the preceding 6 months rose from 27 percent to 82 percent using no-nose saddles.
According to them, the noseless saddle also resulted in significant increases in erectile function.
"No-nose saddles are a useful intervention for bicycling police officers alleviating pressure to the groin and improving penis health. Different saddle designs may require some re-learning of 'how to ride a bicycle,' but the health benefits to having unrestricted vascular flow to and from the penis and less penile numbness is self-evident," says Dr. Schrader.
Most bicycle police officers were able to effectively use no-nose saddles in their police work, and 97 percent of officers completing the study continued to use the no-nose saddle afterward.
The study is appearing in the latest issue of The Journal of Sexual Medicine.
