Understanding PSA

PSA levels can also go up for other reasons. For example, riding a bicycle can put pressure on the prostate and cause a temporary spike in your PSA level. The same is true for ejaculation during sex or masturbation. In general, these activities cause PSA levels to rise only a little, and the PSA should return to normal within several days.


Did you ride a bicycle, have sexual intercourse or ejaculate in the 48 hours before blood was drawn for your PSA test?
