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.
