[|Human|] About 6 months ago I began having issues with my semen. It started  with me finding red blood spots mixed in.  After a couple of weeks started to look brownish or rust-like. A month or so later, you could find yellow-ish chunks in it. As gross as that sounds. I went to see my urologist. He looked at me crazy, and sent me home with antibiotics. I finished the prescription and it seemed to go away. About 2 weeks ago, it started again. Now reddish semen, and seems to be more than normal. I am 31 with 3 healthy kids, and have had no other health conditions. I have had a vasectomy about a year and half ago. Please help. Starting to worry about this.
[|AI|]  Hello, This is probably blood in the semen. In most cases, there is no serious issue. However, we need to make sure there is no injury, infection or tumor. We will advise some tests to find out the cause.  Although there are a number of tests, we go in stepwise manner. Firstly do semen test for culture and urethral swab to look for infection. Next do USG scrotum and THUS (Transreactal ultrasound) to look for your balls and the prostate gland.  If still problem persists you may need other blood tests like AFP, Chat Doctor and even sometimes MRI scan. But most cases subside spontaneously without any concern.  Hope I have answered your query. Let me know if I can assist you further. Take care
