Semen analysis test results- we are so confused!

Holly
So we had a semen analysis done, received the results and the eval was "normal" but on the lower end of normal. His numbers were way higher than normal and motility was great but we are confused. But my question is, listed under abnormalities was amorphous head sperm with thick midpiece. Does this mean all of his sperm are abnormal? Does that also mean this is the reason why we haven't conceived yet? I am waiting til tomorrow to call the dr and see what we need to do. I was just wondering if anyone here was going through the same thing. Any advice is appreciated!
