Mine's a Selle Italia Trans Am Lady . This is the website http://www.selleitalia.com/. Don't know if you can get them in the US but they're very good.

Like emily_in_nc I can't ride a saddle without a cutout. It's just too painful on the delicate bits!

You could also look at your bike set up - the angle of my handlebars meant I was quite stretched out - hence the extra pressure on the front of my saddle, so I tilted the bars up just a touch so I was a bit more upright and that's also made a difference.
