So I had low testosterone and several urologists felt that increasing it would bring my morning wood and sex drive back...it didn’t after doubling my testosterone from 250 to 500. I did a ultrasound without an erection injection twice and it came out that I had perfect blood flow. Then I recently did an ultrasound with an injection and they said I had vascular disease. My other doctor had his ultrasound expert check it out and he doesn’t believe the test is right. but i really don't know. i do know i'm not getting morning wood, libido, or random erections. My se drive is shot. If I had vascular issues would I still get horny and just not fully erect or how does it work?
