Anyone know if the study by Oremek et al, Journal Clinical Chemistry 1996, has stood the test of time? He found that psa right after 15 minutes of stationary bike riding rose.
Trying to get better handle on my psa, taken similarly, to assess treatment options.

I think it has. When bike riding on a saddle type seat, you're basically siting on your prostate. The pressure and movement of the prostate causes extra PSA to enter the blood. At least that's the theory.

Normally it's recommended to avoid bike riding, sex, and heavy lifting two days before the blood draw.

Have it re-done with no bike riding or sex for 48 hours before.

Ha! PSA at MSKCC down from 23.8 to 20.44. Small steps forward.

It seems that we have an inordinately high number of serious bikers on PCa forums, and I've wondered if there are any studies about the possibility of riding exacerbating either PCa or recurrence.

If that were the case, we would see a larger incidence of PCa in countries where people bike more tha in the US (for example the Netherlands). I'm not aware that such is happening.
