Objective:To sonographically investigate whether mountain bikers have a higher prevalence of scrotal abnormalities compared with on-road cyclists. Design:We studied 85 male mountain bikers (mean age: 25 years; range 17-45 years) and 50 male on-road cyclists (mean age: 23 years, range 15-46 years) with regard to scrotal findings on ultrasound (US). Setting:Medical University Innsbruck, Austria. Participants:Only males who gave a history of extensive mountain biking or on-road bicycling (2 hours… 

Ultrasonographic and Doppler findings of subclinical clitoral microtraumatisms in mountain bikers and horseback riders.

Five out of the six subjects, the ultrasonographic assessment of the clitoris evidenced a disseminated clitoral microlithiasis, and the chronic traumatisms may be responsible for microhematomas, inflammation, and/or degenerative processes at level of the vagina.

Mountain Biking–Related Injuries Treated in Emergency Departments in the United States, 1994-2007

Girls and women may be more likely than boys and men to sustain more severe injuries requiring hospitalization and more can be done to improve safety and reduce injuries in this popular recreational activity.

Saddle Pressures Factors in Road and Off-Road Cyclists of Both Genders: A Narrative Review

The aim of this review was to summarize in a narrative way the current literature on the saddle pressures and to present the factors that influence saddle pressures in order to prevent injury risk in road and off-road cyclists of both genders.

Gonadal Function in Male Mountain Bikers

In conclusion, male mountain bikers have lower testosterone concentrations compared to controls, and this alteration cannot solely be explained by testicular dysfunction.

Mountain Biking Injuries in Children and Adolescents

The causation and risk factors associated with injury among young mountain bikers, and recommendations to minimize trauma and enhance optimal performance and long-term enjoyment in this outdoor sport are provided.

Mountain Biking Injuries

The importance of race-day management strategies and monitoring the injury trends are discussed, including bike fit, which provides the clinician with postural correction during the sport.

Pediatric and adolescent injury in mountain biking

Reducing mountain biking-related injuries will require multiple strategies that integrate approaches from education, engineering, and evidence-based safety measures and their enforcement.

Male Athletic Activities and Their Effects on Semen and Hormonal Parameters

These include the effects of exercise on semen parameters, hormonal axes, and testicular health, and the prevalence and particular relevance of anabolic steroid use by athletes and the impact of steroid use on fertility are reviewed.

Classics in abdominal radiology: a “scrotal pearl”

The pathogenesis of scrotal pearls is unclear and proposed etiologies include torsion of an appendix testis or epididymis which subsequently calcifies, chronic inflammation and resultant fibrosis of the tunica vaginalis, or repetitive microtrauma similar to that which occurs in mountain bikers.

Can ultrasound help to manage patients with scrotal trauma?

The pivotal role that ultrasound can play in the accurate triage of patients with scrotal trauma to surgical or conservative management is described, with an emphasis on blunt trauma.

US findings in the scrotum of extreme mountain bikers.

US shows a significantly higher prevalence of extratesticular and testicular disorders in these mountain bikers compared with nonbikers.

An epidemiological analysis of overuse injuries among recreational cyclists.

Significant differences were observed between male and female cyclists' training characteristics, and the odds of female cyclists developing neck and shoulder overuse injury/complaints were 1.5 and 2.0 times more, respectively than their male counterparts.

Effect of changing the saddle angle on the incidence of low back pain in recreational bicyclists.

The incidence and magnitude of back pain in cyclists can be reduced by appropriate adjustment of the angle of the saddle by creating an anterior inclining angle.

Erectile dysfunction after a long-distance cycling event: associations with bicycle characteristics.

If the associations described are causal, then cyclists on a long-distance ride may be able to decrease the risk of erectile dysfunction by riding a road bicycle instead of a mountain bicycle, keeping handlebar height lower than saddle height and using a saddle without a cutout if perineal numbness is experienced.

Impotence and nerve entrapment in long distance amateur cyclists.

The frequency of impotence, numbness of the penis, hand weakness and sensory symptoms from the fingers in bicycle sport may be higher than hitherto recognized.

Ulnar and Median Nerve Palsy in Long-distance Cyclists

Cyclist's palsy occurs at high rates in both experienced and inexperienced cylists and steps may be taken to decrease the incidence; these include wearing cycling gloves, ensuring proper bicycle fit, and frequently changing hand position.

Bicycle riding and its relationship to the development of erectile dysfunction.

The overall prevalence of erectile dysfunction in the cycling community does not appear to be greater than that of historical controls and previously suggested alterations in riding habits may not change the prevalence of ED among cyclists.

Bicyclist's vulva: observational study.

Six women, aged 21–38 years, had a unilateral chronic swelling of the labium majus after a few years of intensive bicycling (an average of 462.5 km per week) and all six had typical unilateral lymphoedema which was more severe after more intense and longer training.

The Ultrasound Investigation of Scrotal Swelling

The objectives of this study were to: (1) establish the causes of scrotal swelling in the hospital catchment population; (2) define the role of high frequency ultrasound examination in the management
