Hello, I am a 61 year old African American male. I have had a few bouts of hematuria, but have a long history of hematospermia. I have had all the major workups, cystoscopy,IVP,CT Scan, MRI of the prostate and most recently fulgaration of the blood vessels in the urethra. I have been on Cipro 2-3 times, Septra and now my Urologist has me on a 25 day regimen of doxycycline 100mg. Why can't the cause for this problem be detected and why has this condition been so persistent. What will resolve this condition?
