What if it doesn't have the bit that goes between your legs?
I bought a seat like that because I understand that the normal bike seats put pressure on that area in a way that can lead to impotence. I haven't tried the seat yet because I'm lazy, so I don't know how comfortable it is. Though even if it isn't comfortable, it's a trade-off.
It's a very small percentage of the population that is affected by bike seats without center channels. It may help you, it probably won't harm you.
A slight warning there is some concern that the cut out collapses as the saddle ages, causing the padding to pinch your anatomy rather than support it. The less pressing on your saddle the less of a concern this is.
The best place to have padding while riding your bike is against your anatomy. Wear a chamois if you're planning on riding longer distances. You can get them as either the classic spandex or as a pair of padded briefs you wear under some shorts.
The most important part to bike saddle fitting is thus:
A saddle designed to support the width of your sit bones
A saddle designed for the posture you ride your bike with (a euro style city bike needs a much different saddle than a keirin race bike)
