CDC – Bicycle Saddles and Reproductive Health

Bike-mounted police officers

Over the last several years, NIOSH researchers have investigated the potential health effects of prolonged bicycling in police bicycle patrol units, including the possibility that some bicycle saddles exert excessive pressure on the urogenital area of cyclists, restricting blood flow to the genitals, resulting in adverse effects on sexual function.

NIOSH worked with several police departments with bicycle patrols to conduct reproductive health research. In these studies NIOSH did more than assess a problem; it also tested a solution and published recommendations. Several bicycle saddle manufacturers have developed saddles without protruding noses. NIOSH has investigated whether these saddles, which remove the pressure from the urogenital area, will alleviate any potential health problems.

NIOSH Scientific Papers on Bike Saddles

Women’s Bike Seats: Does handlebar level damage the pelvic floor in female cyclists?
A study of competitive female cycles using traditional bicycle saddles comparing those with their handlebars above or level with the saddle with women whose handle bars were lower than the saddle. The study reports that that lower handlebars increase pressure to the genitals and is associated with a decrease in genital sensation.

Women’s Bike Seats: A Pressing Matter for Competitive Female Cyclists
A study comparing competitive female using traditional saddle and those with a cut-out area. Bicycle saddles with the cut are supposed relieve pressure to the genital area improving saddle comfort. This study indicates that bicycle saddles with a cut-out area actually increased genital pressure in female cyclists compared to traditional bicycle saddles.

Cutting off the nose to save the penis
A study evaluating the effects on male bicycle police officers using no-nose (noseless) bicycle saddles for 6 months. The study data indicate that no-nose saddles eliminate a large portion of pressure to the groin compared to traditional saddles. Erectile function and feeling in the penis improved after using no-nose saddles for 6 months.

Genital sensation and sexual function in women bicyclists and runners: Are your feet safer than your seat?
A comparison study assessing the health effects of bike saddles on female bicycle police officers was planned. However, as there are relatively few female biking officers in any given police department, women in bicycle clubs were selected as a substitute population due to their similar hours of riding per week. The study data indicate that there is an association between bicycling and decreased genital sensation in competitive women bicyclists.

Effects of Bicycle Saddle Designs on the Pressure to the Perineum of the Bicyclist
A study conducted with cooperation from the International Police Mountain Bike Association measured perineal

CDC – Healthy Places – Transportation and Health Tool

“Transportation choices play an important role in building and maintaining healthy communities. The Transportation and Health Tool can help create safe and convenient transportation networks in communities. I look forward to continuing our collaboration with the U.S. Department of Transportation to make healthy transportation—biking, walking and taking public transit—the easy choice.”

Patrick Breysse, Director, CDC’s National Center for Environmental Health and Agency for Toxic Substances and Disease Registry

The Healthy Community Design Initiative, also known as the Built Environment and Health Initiative, is no longer a funded program and the information on this website is not being reviewed and updated on a regular basis.


The online Transportation and Health Tool gives transportation decision-makers, health officials, and the public easy access to data to understand the health impact of an existing transportation system or proposed transportation project. The tool provides data on 14 transportation and health indicators for U.S. states, metropolitan statistical areas, and urbanized areas. The indicators measure how the transportation environment affects health in the following areas:

  • Safety. Motor vehicle crashes are one of the leading causes of death in the United States. By providing transportation options and improving roadway facilities, transportation agencies can reduce the incidence of motor vehicle crashes.
  • Active transportation. Transportation agencies and their partners can help people lead more active lifestyles by giving them options for getting to places they need to go without driving. They can also reduce the distance between destinations people travel to satisfy daily needs.
  • Air quality. Air pollution has been linked with heart disease and respiratory illnesses, including asthma. Improving transportation system efficiency and supporting cleaner vehicles and fuels can improve air quality.
  • Connectivity to destinations. Providing a well-connected, multi-modal transportation network increases people’s ability to access destinations that can influence their health and well-being. For example, an effective transportation network can provide access to jobs, health care services, and parks.
  • Equity. Negative health effects related to transportation systems often fall hardest on more vulnerable members of the community, such as low-income residents, communities of color, children, and older adults.

The tool also includes 25 evidence-based policies, strategies, and interventions for improving health outcomes through transportation investments. Such investments include expanding walking, bicycling and public transit infrastructure, promoting connectivity, and improving roadway safety.

The Transportation and Health Tool was jointly developed by the Centers for Disease Control and Prevention and U.S. Department of Transportation in partnership with the American Public Health Association. CDC’s Healthy Community Design Initiative led a team of experts from multiple organizations to design, develop, and release the tool.

Health Advantages Of Bicycle Using

Bicycles could be ridden nearly all over the place outside, including the sidewalks, but before you do this, you could perceive a number of things. The sidewalk is a good place for youths to journey their bikes in the suburbs because they’d not have to worry about vehicles as much. Also, lastly, the aim of this article is not to encourage folks to trip their bikes drunk. Bicycles that aren’t ladies-particular include males’s saddles, which aren’t designed for the female anatomy.

You cannot access the back of the automobile when you have got bicycles on the rack. The two finest places to mount a bike rack are on the front of the travel trailer (on the tongue), or on the rear of the trailer (on the frame). Rear bicycle lights are all the time pink and are strictly to help others behind you to see you.

Although the more expensive than other kinds of batteries used in electrical bicycles, it is far inexpensive in the long run than frequent journeys to the gas pump to fill the automobile’s gasoline tank. They are among the most recognized industry manufacturers, and manufacture a variety of bicycles to be able to meet the demands of riders across the world.

The purpose of this story will not be scare people into wearing helmet to indicate the usual excuse of I do not trip on the street or I don’t ride near cars. More often than not, a firmer saddle could be better particularly for longer rides. Also, you can regulate your bicycles by means of the tow car’s rear window whereas traveling down the road.

HEALTH TIP: Get off your bicycle seat and stroll around each 25 minutes or so to get the blood movement to vital unmentionable parts of your body. Some kids may wish to experience their bikes fast on sidewalks; they must know that aged individuals sometimes use the sidewalks to stay out of the streets.…
