from yesterday's NYTimes. Looks like bicycle seat design will be the new ongoing hot topic.
A raft of new studies suggest that cyclists, particularly men, should be careful which bicycle seats they choose.
The studies add to earlier evidence that traditional bicycle saddles, the kind with a narrow rear and pointy nose, play a role in sexual impotence.
...The link between bicycle saddles and impotence first received public attention in 1997 when a Boston urologist, Dr. Irwin Goldstein, who had studied the problem, asserted that "there are only two kinds of male cyclists - those who are impotent and those who will be impotent."
