Cutting off the nose to save the penis

Area of Science:

• Occupational Health
• Ergonomics
• Urology

Background:

• Bicycle police officers spend significant time cycling, increasing risk of urogenital paresthesia and sexual dysfunction with traditional saddles.
• Previous research links traditional nosed saddles to adverse urogenital and sexual health outcomes in cyclists.

Purpose of the Study:

• To evaluate the effectiveness of no-nose bicycle saddles as an ergonomic intervention for male police officers.
• To assess the acceptance and impact of no-nose saddles on officer health and function.

Main Methods:

• Recruited male bicycle police officers from five U.S. metropolitan areas.
• Assessed erectile function (IIEF), perineal pressure, penile tactile sensitivity, and nocturnal erections (Rigiscan) before and after 6 months of exclusive no-nose saddle use.
• Utilized computerized biothesiometry for sensitivity assessment and pressure mapping.

Main Results:

• A 66% reduction in perineal saddle contact pressure was observed (P < 0.001).
• Significant improvements in penile tactile sensitivity (P = 0.015) and erectile function (IIEF scores, P = 0.015) were noted.
• Urogenital numbness decreased, with self-reported paresthesia incidence dropping from 27% to 82%; Rigiscan measures showed no significant change.

Conclusions:

• No-nose bicycle saddles are an effective ergonomic intervention for police officers, with high acceptance.
• The intervention significantly reduced perineal pressure and improved penile health indicators, including erectile function and sensation.
• While Rigiscan results were unchanged, suggesting longer recovery may be needed, the overall findings support no-nose saddles for officer well-being.
