One million sperm count

My DH has a sperm count of one million and tested twice came out the same both times. He also has vertices veins that is like a Internal blanket heating up his sperm per the urologist dr.  The urologist dr did blood work as well his testosterone level was also low. It did not seem like the dr wanted to do surgery in the veins because wouldn't boost count enough . And then not really any other hope really sad does anyone have success stories or help hope for first child wishing for a miracle and very depressed:(
