Erectile Dysfunction

The objective of a recent study by J.

M.

Gemery, S.

K.

Reid, and colleagues from Boston University was to create digital three-dimensional (3D) models of a pelvis, pudendal arteries and bicycle seats to evaluate the potential sites of compression of the vessels.

The study is published in the January 207 issue of BJU Int.

The authors hypothesized that the seat type in conjunction with the rider's position differently affects the orientation and compression of the pudendal arteries.

After using 3D models of one male pelvis and three bicycle seats, the authors then correlated with lateral radiographs of a seated rider to determine potential vascular compression between the bony pelvis and seats at different angles of rider position.

Penile hypoxia secondary to decreased blood flow might be injurious, and has been postulated to promote trabecular connective tissue synthesis, which could impede the achievement of erection.

There have been studies that have shown a decrease in mean transcutaneous penile oxygen pressure at the glans from 60.5 mmHg, standing before cycling, to 17.9 mmHg after 15 minutes of cycling while seated.

Analysis of the resul...
