While not known specifically to cause ED intense amounts of cycling can cause issues in the groin, penis, and prostate. The seated position found in biking can lead to extra pressure on these areas of the anatomy and has been known to cause acute prostatitis although there is no known link to prostate cancer or other chronic prostate concern specifically. Biking is also known to potentially cause spermatoceles and/or varicoceles in the scrotum. These conditions are not known to lead to ED either, however, any change to the tissue has potential for leading to pain with erections or ejaculation which can be seen as ED in one way. One should always do a regular testicle self-check to notice if anything is new, different, or painful. As well if any new symptoms of increased frequency of urination or pain with urination occur once should seek care.
