Introduction: An increase in the incidence of the erectile dysfunction of the penis was observed in those cyclists that cover long distances. All the theories converge on the identification of the perineal region as the critical point.

Objectives: Identification of a bicycle saddle model suitable for cyclists covering long distances, capable of limiting compression of the structures of the pelvic fl oor, and thus protecting the blood perfusion of the penis and preventing possible consequences in erection.

Materials and methods: comparison between the new geometrical conception saddle (SMP) and one of the models most frequently used by professional cyclists. Assessment of the degree of compression exerted by the two saddles, on the vascular structures of the perineum, by measuring the partial pressure of the transcutaneous oxygen of the penis in 29 healthy, cyclist volunteers. Readings of the transcutaneous O2 pressure carried out after 3 and ten minutes of static seating. Subsequently the values of the PtCO2 were determined for 15 minutes while pedaling with the subject at 60° and in stable haemodynamic conditions.

Results: Data analyzed statistically (test t Student, examination of the confidence interval) demonstrate of the net superiority of the SMP saddle in preventing vascular compression of the perineal structures with statistically important results. The true innovation brought about by the SMP saddle is its capacity of interfering scarcely on the blood perfusion of the penis, maintaining limited dimensions, especially in width, parameter considered to date as an essential factor in the protection of the compression on the perineal structures. It is the geometry of this saddle that, by redistributing the body weight onto the buttocks, the ischial tuberosities, the ischium freeing the perineal plane, prevents the squashing of the neurovascular structures that run medially to the ischial tuberosities. Furthermore, the depression in the rear part prevents the coccyx from touching the saddle, thus preventing repercussions caused by the unevenness of the ground that may affect the spine.

In our study, the SMP saddle has shown to be by far the most efficient in protecting the blood perfusion of the penis compared to one of the saddles most frequently used by professional cyclists.

Conclusions: validation of the efficacy of the SMP saddle in limiting the compression on the pelvic floor even though it has dimensions, especially in width, compatible with the needs of the cyclists that cover long distances.
