Is Biking Bad for the Bedroom?
In September 1997, Ed Pavelka, a columnist with Bicycling magazine, made a startling revelation: He had erectile dysfunction from riding his bike. He wrote at the time: "...tests revealed that the blood flow to my penis had become so restricted that I was incapable of an erection firm enough for sexual intercourse."
Pavelka's conviction that biking had led to his problem was soon backed up by medical authority. Irwin Goldstein, MD, a specialist of erectile dysfunction with the Boston University Medical Center, was widely quoted in the press saying that all male cyclists risked erectile dysfunction, and that they should consider giving up the sport if they enjoyed sex.
Alarmist Advice or Scientific Proof?
Goldstein, whose patients included a number of cyclists with sexual dysfunction, performed a study at Boston University Medical Center to investigate the connection. His 1997 study showed that cyclists experienced more sexual dysfunction than athletes who didn't bike. Cyclists' complaints included erectile dysfunction, groin and penile numbness, and problems urinating.
But what was it about cycling that led particularly to erectile dysfunction? Goldstein's study hadn't uncovered a cause, but another study done at the University of California, San Diego, offered an explanation. The study -- done in conjunction with Serfas, a bicycle accessory company in Lake Forest, Calif. -- found that the rub lies not in cycling itself but in the seats.
"Men can develop erectile dysfunction after sitting on a hard bicycle seat for many hours because they compress an area of the anatomy known as the perineum," explains Ken Taylor, MD, a former assistant clinical professor of family medicine at UCSD and a co-researcher in the 1999 cycling-impotence study. The perineum is the area between the anus and the scrotum.
Tim Roddy, M.D., a urologist in Edmonds, Wash., agrees that the pressure of sitting on a bike seat can cause the problem: "A man can squeeze off some of the vital arteries and nerves necessary for normal sexual functioning by sitting on a hard bicycle seat too long," he says.
If the Seat Fits
Serfas, a manufacturer of biking accessories, set out to design a seat that would shift the rider's weight off the perineum. The result, called "the Eliminator," has a long groove down its middle and is hollowed out in front. In April 1999, researchers tested the newly designed seat on 15 regular cyclists, most of whom pedaled between 150 and 300 miles weekly.
The results? Though 80% of those using a conventional seat suffered numbness, only 14% of those using the new seat did. Serfas now offers several seat models for street and mountain bikes.
More Studies, More Seats
Specialized Bicycle Components, Inc., of Morgan Hill, Calif., also offers seats designed to help men ride safely. Medical designer Roger Minkow, MD, helped develop the Body Geometry Saddle seat with input from urologists and police bicycle divisions. The Specialized seat is very narrow and has a V-shaped wedge cut from the rear.

Erectile Dysfunction Guide
Indication
Uroxatral® (alfuzosin HCl 10 mg extended-release tablets) is an alpha1-blocker for the treatment of the signs and symptoms of BPH.
Important Safety Information
Do not take UROXATRAL if you have liver problems or if you are taking antifungal drugs like ketoconazole or itraconazole, or HIV drugs like ritonavir.
UROXATRAL can cause a sudden drop in blood pressure, especially when starting treatment. This may lead to fainting, dizziness, and lightheadedness. Do not drive, operate machinery, or do any dangerous activity until you know how UROXATRAL will affect you. This is especially important if you already have a problem with low blood pressure or take medicines to treat high blood pressure. There may be an increased risk of low blood pressure and fainting when taking UROXATRAL in combination with blood pressure medication or nitrates, or erectile dysfunction medication.
If considering cataract surgery (clouding of the eyes), tell your eye surgeon that you are currently taking UROXATRAL or have previously been treated with an alpha-blocker.
Before taking UROXATRAL, tell your doctor if you have kidney problems.
Also, tell your doctor if you or any family member(s) have or take medications for a rare heart condition known as congenital prolongation of the QT interval.
BPH and prostate cancer can cause the same symptoms. However, UROXATRAL is not a treatment for prostate cancer.
The most common side effects with UROXATRAL are dizziness, upper respiratory tract infection, headache, and tiredness.
Please see UROXATRAL full prescribing information.
