Since the late 1990s, saddle design has seen major innovation. A big impetus came from a prominent doctor's contention that sitting on a bike seat might lead to damaged nerves or blood vessels in some men. This risk, plus the occasional bout of temporary genital numbness that many riders experience, put designers into action. The result is a new generation of saddles with special shapes, padding or cutouts to reduce crotch contact and pressure. As a side benefit, riders have found that they experience fewer saddle sores on these seats. Saddle selection is highly individual. Despite how effective a saddle might look or how highly praised it might be by a riding buddy, there's no guarantee that it will be comfortable for you.
