Do mountain bikers have a higher risk of scrotal disorders than on-road cyclists?

Two things scare me about that article.

1 - PTD somehow found it. (sorry PTD )

2 - Someone did the study in the first place ; who thinks up these things? :eek::eek:

Not reading it. Thanks.

I heard about it on the Ben Greenfield podcast.

"In addition to clinical evaluation, a standard ultrasonographic examination of the scrotum was performed using a linear array transducer operating at a frequency of 8.0 MHz (Acuson Sequoia 512)."


8.0 MHz is the sexiest of the frequencies.

Having worked in research, here is what happens:

Get funding to look at blood flow and medical disorders associated with spending time in the saddle. One PhD student cops on during a lab review meeting that even though it could be a fluke or it may be an actual thing the words "statistically siginificant" popped into his head. Then popped into his head the phrase "First Author" and then he actively starts looking for this divide.

Can't get behind the paywall but I imagine it was looking at long distance/year in their eyes and the number of volunteers happened to have a lot of MTBers and then someone copped the potential link while scanning through the data.

I had to look up how the Dr. came up with this:

I heard he was having trouble trying to evaluate the long term effects of MTBing at the time.

I've gotten concussed, fractured collarbones, lost skin, hurt wrists when road cycling. My knackers have not had any damage. About ten years of at least 150km a week, sometimes 450km.


In my teens I did about two years of light MTBing, my knackers always gotten a hammering from stems and top tubes.

N=1 but is good enough for me when N=me

Thinly veiled 'Mountain Bikers have bigger balls than road bikers' statement, but sure I knew that already!

I'm not sure scar tissue counts.

Not scar tissue, stretch marks

Sounds like you have a feel for this sort of thing.....

Sounds like a load of ole balls to me :pac:

I've only ever hurt "the boys" off the stem,and it is usually because of trying to take off with the wheel in a hole in a high gear.

Genuine question,I can ride the MTB on trails for hours on end,and be fine,but cycling to or from the woods which is maybe 15kms of road and I lose feeling in my junk. Is it the fit of the shorts, the saddle,or is it that grinding an MTB down the road on knobblies doesn't make you stand up out of the saddle as much? Tried a BG saddle and a Selle italia off my other bikes,made no real difference,so I kept with the Prologo road saddle,which I find the best fit for the position on the bike.
