Poker Fox,

Your statement is retarded. Since you couldn't be arsed to do your own research, here are some abstracts of recently published and peer-review articles. Cycling may be a contributing factor of impotence in some individuals but to say "There are 2 kinds of male cyclists: impotent ones, and ones that will be impotent eventually." is pretty dumb.

BICYCLE RIDING AND ITS RELATIONSHIP TO THE DEVELOPMENT OF ERECTILE DYSFUNCTION

ABSTRACT

Purpose:

Researchers have suggested that cycling is a hazard to the sexual health of men. Insufficient data have left cyclists skeptical of this claim. We explore risk factors within cycling that may put riders at risk for the development of erectile dysfunction (ED).

Materials and Methods:

We performed an Internet based survey of cyclists to examine factors associated with cycling that might contribute to ED as defined by the International Index of Erectile Function. A total of 688 cyclists were included in the analysis ranging in age from 18 to 77 years.

Results:

ED prevalence was 17% (115 of 688). Although results from univariate analysis revealed a correlation between ED and several tested variables, none proved to be statistically significant after controlling for age.

Conclusions:

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

ERECTILE DYSFUNCTION AFTER A LONG-DISTANCE CYCLING EVENT: ASSOCIATIONS WITH BICYCLE CHARACTERISTICS

ABSTRACT

Purpose:

We conducted a prospective cohort study to examine the relationship between bicycle characteristics and the occurrence of erectile dysfunction.

Materials and Methods:

Subjects consisted of 463 cyclists completing a cycling event of at least 320 km who were free of erectile dysfunction before their event.

Results:

The cumulative incidence of erectile dysfunction after the ride was 4.2% (95% confidence interval [CI] 2.4%–6.8%) and 1.8% (95% CI 0.7%–3.8%) 1 week and 1 month after the event, respectively. Bicycle characteristics associated with an increased risk of erectile dysfunction included a mountain bicycle compared with a road bicycle (risk ratio [RR] 4.1, 95% CI 1.6–12.5), and the relative height of the handlebars parallel with or higher than the saddle compared with the relative handlebar height lower than the saddle (RR 3.0, 95% CI 1.1–9.3). Perineal numbness during the ride was experienced by 31% of the cyclists and was associated with erectile dysfunction (RR 4.4, 95% CI 1.6–12.7). Saddle cutouts were associated with an increased risk of erectile dysfunction among those who experienced numbness (RR 6.0, 95% CI 1.3–27.1), but the association was reversed among those who did not report numbness (RR 0.3, 95% CI 0.0–2.5).

Conclusions:

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.

Abstract

Purpose:

Bicycle riding is one of the most popular means of transportation, recreation, fitness and sports among millions of people of all ages who ride on road and off road, using a variety of bicycle types. It is also a readily available form of aerobic non-impact exercise with established cardiovascular beneficial effects. Bicycles are also a common source of significant injuries. This review focuses upon the specific bicycling related overuse injuries affecting the genitourinary tract.

Materials and Methods:

MEDLINE search of the literature on bicycling and genitourinary disorders was performed using multiple subject headings and additional keywords. The search yielded overall 62 pertinent articles. We focused primarily on the most prevalent related disorders such as pudendal nerve entrapment, erectile dysfunction and infertility. The potential effect of bicycling on serum PSA level was also discussed in depth in view of its recognized clinical importance. Infrequent disorders, which were reported sporadically, were still addressed, despite their rarity, for the comprehensiveness of this review.

Results:

The reported incidence of bicycling related urogenital symptoms varies considerably. The most common bicycling associated urogenital problems are nerve entrapment syndromes presenting as genitalia numbness, which is reported in 50–91% of the cyclists, followed by erectile dysfunction reported in 13–24%. Other less common symptoms include priapism, penile thrombosis, infertility, hematuria, torsion of spermatic cord, prostatitis, perineal nodular induration and elevated serum PSA, which are reported only sporadically.

Conclusions:

Urologists should be aware that bicycling is a potential and not an infrequent cause of a variety of urological and andrological disorders caused by overuse injuries affecting the genitourinary system.

All you have to do is watch the Tour to know PF is full of crap, most of the guys on the podium have their kids with them and they are going to spend more time in the saddle in one season than most recreational cyclists do in a decade.

The tour and its riders are horrible examples to use since they could be *protected* by the increased testosterone from "falls" or other sources [img]/images/graemlins/grin.gif[/img].

Thought the one statement in the clinical examples quoted was interesting though

I would have thought just the opposite was true.
