The solution is to be sure you’re fit properly on your bike. There is WAY more contributing to numb junk than just the saddle shape. Seat to high/low, bar reach to short/far, bar drop too low/high, saddle to far forward/back, saddle angle - all of these contribute to placing your sit bones in the correct location on your saddle or not. But even with all this considered you do need to have a properly fit saddle. Noseless won’t do it for everyone. What I’ve found more important are:
1) The width of the sweetspot where your sit bones rest on the saddle. Specialized actually sells their high end saddles with various widths. The dealer should have you sit on a gel butt-gauge to measure your spacing.
2) the taper from the sweetspot to the nose. Everyones’ legs are different. I’ve found if this doesn’t taper off quickly it will cause circulation problems, pressing against my femoral artery
3) the width of the saddle nose. Somewhat similar affect to No 2, but more so when I’m in the drops.
4) prostate cuttout. Keep the pressure off of your jewel.
Once I rode with the Specialized Toupe’ on my race bike, I went back and got one in the same size for my travel bike, my mountain bike, and both of my tandems. One ride on an old saddle and I knew it had to be replaced. I’d highly recommend this saddle, but I also know that everyone’s geometry is different. A good should should let you try out a saddle before buying, but then we’re talking about $100-$200 saddles. If your shop doesn’t have a loaner to try, find another shop.
Now, to address the OP.. Every few years some article comes out about how bike seats will make your dick fall off, and every time it’s just hype, usually trying to sell you some knew gimmick saddle. The “noseless” saddles are primarily targeted at TT bikes where the UCI fit rules require a minimum setback from the BB to the saddle nose. A noseless saddle lets the rider move it more forward to better accommodate an aero position without incurring the wrath of the UCI. Leaning far forward in the TT position also rolls the prostate more forward on the saddle and can sometimes position it out of the cutout. Some newer saddles are taking the cutout all the way through the nose for those times when you’re off the front of the pack, sitting out on the nose of your saddle to get low and drill the pace hoping to stay away - without your junk going numb.
So if your questions was truly motivated by your dissatisfaction with your current saddle, go find a shop that will let you demo an ergo saddle like the Toupe’ and find the one that is right for you. But if you’re just getting worried because some journalist told you your dick is going to fall off, all I can say is to relax. The next scare article will be right around the corner.
