At a recent conference, they mentioned that getting on a bike seat that sits on the perineum and puts weight there causes erectile dysfunction, You want a seat that is wide in the back and does not have a narrow area for the perineum.

Others can give you some exact styles. I bought a bike seat that looks like this, But they say it’s no longer available. Something similar is probably what you want.

@gobucky I posted on this thread the other day specifically on this topic... I think I have a great recommendation for you. That's a fair bit of mileage! THE MOST comfortable seats I have tried (by a long shot) are the "NinetyK" brand (ninetyk.com). I have been a serious mountain, and to a lesser extent road, rider for 34 years (when riding road to train for mt biking events, I was putting in ~3000 km in a training season April - September). I went through a painful lapro RP procedure in August 2023. I experienced profound perineum sensitivity and pain for a long time. I ended up buying a recumbent stationary cycle with a padded bench seat just so I could pedal a bike for almost a year after surgery. I have tried multiple brands of seats and have found several that are pretty good - Ergon makes some good saddles; SQ Labs also makes some good saddles. BUT, by far, the most comfortable has been my NinetyK Nirvana saddle. I am back riding heavily-technical, steep mountain terrain in the North Shore, Sea-to-Sky region of BC, Canada. For road and/or gravel, you may wish to consider the NinetyK "The Jam"; "The Cure"; or the "Yes" saddle. They don't let you post links on the site here but if you go to ninetyk.com, you will find these. I also posted about a supercool, very innovative product called the "Aenomaly Switchgrade". This allows you to change the angle of your seat on-the-fly. It was primarily developed for mt biking, but would work for general cycling and gravel (especially if you log any significant climb-descend transitions). The device allows you to put your seat at the optimal angle for flat, climbing, or descending with an easy-to-access lever under the front end of the seat. It is amazingly well-crafted, robust and effective at reducing perineum pressure (can also help with back pain often associated with long, steep climbs). You can find it on aenomalyconstructs.com. BTW, I am NOT paid by any of these companies to recommend their products. I am simply sharing what has been helpful for me. Best to you!
