Every night 35 y/o male, penis head turns blue/purple and my penis and testicles are freezing cold. it has also caused a form of ed. testosterone is 651. had ct with contrast. vascular dr said everything was fine. urologist said it will pass. help!?

Unless you've had some injury to nerve endings or spinal cord pathology, I wouldn't be concerned about those symptoms. I would take the advice of your urologist.

You had a lot of expensive tests and exams!. If there was any permanent abnormality then the coldness and color change would not be confined to night. Wear a warm underwear and avoid cold temperatures at night. Lead a normal sex life. I think you will be fine.
