This is a normal post one reason I've never been interested in participating in cycling as a sport, as opposed to just riding to work, is that I hate those small seats
They hurt your arse, and apparently leads to a fairly high percentage of impotence
Give me an upright stance and a dutch bicycle seat with the springs underneath any day.

This is a normal post upright stance is fine for short distances
And you can sit up like that for a long way, so long as you don't mind battling the wind more than you have to. But narrow saddles *are* more comfortable. big squashy things will really hurt after upwards of 20 miles. A serious race bike does force you into a flat back position but a reasonable endurance road bike won't. Horses for course, in other words. But you have even tried riding a pony yet, so don't judge.

This is a normal post it's basically the nose of the bike seat that does most of the damage
so leaning forward increases the weight and pressure on the perineum, while sitting upright distributes it more widely across the buttocks.
With racing seats, blood flow is reduced by 60% to your wang, and pressure on the dorsal nerve has a high frequency of temporary numbness, with eventual permanent damage.
I've gone on quite a few long cycling trips and always with big arse dutch seats. I totally disagree they're less comfortable. I was the only one not complaining by the third day. Pro cyclists probably just go numb after a while so it stops bothering them, and sex would be a distraction from racing anyway. Trust the dutch when it comes to bikes and dikes.

This is a normal post On long rides Dutch seats tend to cut bloodflow to the fémoral biceps ...
And you can buy stub nose saddles that let your ball sack dangle in the breeze.
I use a SMP with a downward « beak » that has the same effect.
There are a wide variety from leather, to gel right up to a plank of carbon fibre, and if you lube, it’s much nicer.

As you seem to rather uniformed, bike now have gears, brakes and pneumatic tires amongst other things.

Grandad.

This is a normal post uniformed?
my opinion about pudendal artery compression and the influence of bycycle seat noses is backed up by a little something called research.
www.ncbi.nlm.nih.gov/pmc/articles/PMC4690354/
www.health.harvard.edu/blog/biking-and-sex-avoid-the-vicious-cycle-201209145290. I'm aware of alternative seat designs, my dutch seat has a snub nose, but crucially you do not see any pro racers using them, hence my original post about why I avoid racing as a sport.

your evidence-free blather about "dutch seats cut bloodflow in fémoral biceps " is either know-nothings crapping on in cycling forums or more likely speculation you've just pulled out of your own arse. Unless of course you can point me towards a paper that might support you? No? Pity

Always happy to teach the ignorant, son

Completely conclusive. You have irrefutable evidence there. No one need ever look into this again.
"A little something called research". You bellend.

This is a normal post "oooh look at me, I have a limited understanding of sample size " - that's what you sound like
that was merely one study, I found 20 in five seconds, all on the same subject, all supporting my opinion about pudendal artery and nerve compression, which you could have too if you actually understood modern research tools. E.g.
onlinelibrary.wiley.com/doi/abs/10.1111/j.1600-0404.1997.tb00104.x

By contrast, Research papers talking about femoral bicep blood flow and seat compression: 0

I often wonder why people bother arguing with me. In the end it makes them look foolish. It would be much better for everyone if people just agreed with my erudition from the outset

This is a normal post Regardless of saddle shape
Your ischial tuberosity (arse bones) should be supporting your weight.
If you're feeling perineal pressure whilst using a traditional 'racing' saddle, it's because your posture is wrong, or the bike setup is wrong (most likely the saddle height/angle).
Now, there's no denying that there's a much wider margin for error when using a dutch/ladies style saddle. But the tradeoff is that you're either forced to go slow as fuck, or put far more effort than is necessary to keep up with your significantly more aerodynamic pals.

I currently use a Brooks C13. In the Spring/Summer I do around 180 miles a week on it. Would I recommend it as a beginner's saddle? Fuck no. But when you're riding a bike that has been properly fitted and set up, and you're adopting the correct posture in the saddle, it's significantly more comfortable than a woman's Dutch saddle would be, and I can promise you that I've had absolutely no issues with perineal pain or numbness.

This is a normal post Thank you.
I've done about 3,600 miles this year split between a charge spoon saddle on my commuter bike (a rather nice steel frame, disc brake gravel bike) and my carbon bike which has a fizik antares. I don't have a very aggressive posture any more as I'm old and never work on flexibility at all. But never had any of the problems discussed here.

This is a normal post Mr ICantFeelMyPenis
Again, unlike the waffle that the man in the bike shop tells you about bike set-ups to squeeze some extra cash out of you, it really comes down to some pretty basic physics.
Weight to surface area means that small profile seats, like the Brooks c13, exert more pressure on the body than wider seats with greater surface area contact.
Then you look at where the contact is. The BrookC13 is your typical long nose blade profile, so unless you're upright with 70s dragster handlebars you're going to be experiencing quite a lot of that additional pressure on your perineum. Additionaly, the more give the less that pressure will spike when riding over compression points like the odd bump or pothole. Gel is better than hard seats, but neither comes close to the sprung/padded combination of the dutch style seat.
And there's all these research papers that show this additional pressure is causing you long term damage and impotence. I can understand why the industry would like to downplay this and distract with waffle about biomechanics. there's an awful lot of money in convincing middle-aged men that they're the next Chris Froome (without his asthma steroids, of course) and buy all the super expensive kit to lower the strava times they like to tell the world on facebook, and informing them they're cutting their rooting years short isn't going shift any stock.
As for comfort, it's a bit like if you came to a bar and were offered a padded chair or narrow bicycle seat to sit on all night. You might crap on about gel/carbon fibre and how your unqualified seat expert at the seat shop has personalised your set up based on the his analysis of the biomechanics of your sitting, but I guarantee the chair is the more comfy choice, because it has wider surface area and more padding, just like the dutch big arse sprung bicycle seats.
In conclusion, with an upright stance and a wide snub nosed seat I won't be winning any races, but I'll be more comfortable and less likely to sustain long term cock damage, which is a not insignificant factor in my thinking

This is a normal post I don't believe the impotence issue is low, let alone fairly high
but it is fairly high compared to sitting on a car seat.

This is a normal post The study in European Urology found that narrow seats and narrow seats with a V-shape in the saddle nose decreased oxygen to penis by 82.4% and 72.4%, respectively
I'd hardly call that a trivial finding. sustained lack of blood causes penile fibrosis, an important cause of erectile dysfunction
Another study found:
Numbness of the genital region was reported by 61 % of the cyclists. 19 % of cyclists who had a weekly training distance of more than 400 km complained of erectile dysfunction. The results of the present study showed that there is a deficiency in penile perfusion due to perineal arterial compression. This could be a reason for penile numbness and impotence in long-distance cyclists. Therefore, we suggest restricting the training distance, and taking sufficient pauses during the course of prolonged and vigorous bicycle riding, in order to reduce penile numbness and impotence.
That is 19% self reporting impotence. I'd imagine the actual figure to be higher. 61% reporting numbness again tends to suggest that most cyclist sustain at least temporary nerve damage
So what is your working definition of low and high? Does it have to rip your cock off every time before you start to pay attention to the risk?

This is a normal post Don't sit on those saddle shapes?
As for the second part - that's about 3x my weekly commute. I happily ride 100 miles in a day, but on a big leather touring saddle. I have had back pain, wrist and arm pain, legs have got a bit tired - but not encountered this.

Not on topic, but cycling increases your risk of being hit by a car, but not as much as being a pedestrian. It improves cardiovascular health (presuming you otherwise were not going for a jog), reduces cancer risk according to CRUK.

As for papers , the most recent I had encountered was https://www.sciencedirect.com/science/article/pii/S0022534717777221
via the beeb news. It was a study comparing cyclists swimmers and runners and out of 4000 responders - it concluded:

Cyclists had no worse sexual or urinary functions than swimmers or runners but cyclists were more prone to urethral stricture. Increased time standing while cycling and a higher handlebar height were associated with lower odds of genital sores and numbness.

Not great, but not the common understanding of the issues.

The thing about self reporting and looking at male cyclists is, you are not really looking at a baseline. How many would have had erectile dysfunction that they would have self-reported in the general population? Would that self reporting have been lower, or higher than this sample?

It is all very interesting - and if I thought for a moment my willy was going to fall off, I would instantly put my bike on gumtree. I seem to still piss like a horse too - but that is likely due to too much Pepsi Max. I know that urethras are precious.
