Done Ultrasound Of Urinary Tract And Abdominal, Shows An Enlarged Prostate And Mid Line Cyst. What Should Be Next Step?

Hi, I have a condition of haematospermia for about 4 months. The doctor has done ultrasound of my urinary tract and abdominal. It shows an enlarged prostate and mid line cyst. I was then sent to urologist for further examination. He did a physical exam through my rectum and prescribed me Ciprofloxacin for one month. It didn t work except it was on and off, sometimes blood was there, sometimes there wasnt (atleast not visible to naked eye). Then i told the urologist, it didnt help, he did a Cystoscopy and found everything to be normal inside. Now, i am getting red semen with red dots majority, my urologist has asked me to get an MRI for my prostate, as he thinks there is a flush near my prostate when he did the physical exam after my cystocopy. He explains a flush meaning a fluid type bump. So now i am waiting on the MRI Can you help me with whats really going on? The cause of this whole hematospermia is i ride bicycle during summer, and last summer, i had to brake suddenly and the rod in the middle of the bike (underneath the seat, my pubic area got hit by the rod once. I had pain in my lower abdomen for few days but nothing serious and after a month or so, this bloody semen started. Please help.
