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?

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.
