Babylove I think that the semen being thick and white initially is normal, it liquefies after about 20 minutes. Have you had a s/a done recently? I don't know, I would think 2 years after the surgery, if it worked, there would be sperm in the s/a by now, and maybe the surgery helped, but not enough are coming out to get the job done. I guess I would just go back to the urologist and see if they will find out what's going on and if they won't I'd find someplace that will. Good luck!!
