Good question! I just bought a new road bike and have been looking at after market seats. The newer designs are a bit wider, have more cushioning, and have a depression in the center of the seat that is supposed to relieve the pressure on the peritoneum (sp?). I plan to ride at least ten miles per day over the summer. I am trying to lose the fat from ADT.

It will be interesting to read the replies.

By the way I did some research about PCa and bike riding and most said there was no link. A few years ago there was some buzz to the contrary.

Take care,

Hi don826,

My prostate was very large but I never connected it with riding a bike. I never felt any discomfort even when doing a century ride. I ride a Cannondale R600 with a stock seat. I'm still convinced that the enlarged prostate was due soley to the cancer within.

At this time I am over 5 months past surgery and have been riding for the past 3 months, mostly on a trainer.

I would venture that if you are not experiencing any discomfort it should be okay to ride as you desire. I would certainly recommend that you double check with you doctor though.

Good luck and happy riding,

I guess I am a old guy here, 53 now, I like to ride a bike but I want a comfortable seat. I went back to bike riding after 6 months prostate cancer surgery.  The first bike guy fitted me with  a seat way too narrow for me, when I went back to him he said I could get a larger seat but I should just toughen up my muscles to ride the smaller seat. Toughen up my muscles? I am 53 now (was 52 then) I could care less about toughening up my muscles, I just wanted a seat that would accomodate my ischial tuberosities, I got a wide seat and have been riding ever since to lose weight and stay in shape, NOT to be in competitive events............
my age=52 when all this happened,
PSA went from 1.9 to 2.85 in one year, urologist ordered biopsy,
First biopsy on 03/08, "suspicious for cancer but not diagnostic"
Second biopsy on 08/14/08, 2/12 cores positive for Prostate Cancer on R side, 1 core=5% Ca, other core = 25% Ca, Gleason Score= 3+3=6 both cores,
Clinical Stage T1C
Bilateral nerve sparing Robotic Surgery on 09/11/08, pathological stage T2A at surgery,
No signs of spread, organ contained,
3 0's in a row now, 7 months out
Incontinence gone in early December '08,
ED remains, uro said try oral meds and then trimix for sex only now

...there are tons of good Anatomic gel saddles out there. Holes, splits etc in the seats to help with the discomfort, whatever the cause' may be. Check out a good quality bike shop,  not one of those big box stores and I'm sure the staff would be more than willing to give you advice. I use gel saddle/split on my mountain bike works great for me.  Happy biking!
