Hi, yes thanks for your quick response. I ve noticed recently that my scrotom is purple in color. I exercise every day; bicycle one day, treadmill the next.....always at leas an hour or more. I only got the excercise bike a month ago. Suddenly a couple of days ago I see this purple colored scrotom. I am 69 years old. I ve excercised 6 days a week for 35 years. Am I doing something wrong? I ve started wearing a jock strap. I NEVER did that before. Maybe the free swinging of the testicles is causing this? I ve no other health problems that I am aware. Should I be concerned about this change in color in my scrotum? Oh, yes....after excercise this condition disappears...and sometimes I awaken in the morning with the change in color and then it disappears. Should I be alarmed and see my doctor....family or a urologist?? Thank you, Scotty Oops! my email address is: YYYY@YYYY . Sorry...I didn t realize that I had to provide my email address.
