Thanks for choosing health care magic for posting your query.
I have gone through your question in detail and I can understand what you are going through.
It could be an infection of the prostate
. You need to get a culture and sensitivity done of the spermatic fluid. If there is any infection the same needs to be treated with higher antibiotics for a long time.
Hope I am able to answer your concerns.
If you have any further query, I would be glad to help you.
