I've lost hope :(

We were already having problems conceiving because of my irregular periods. Now on top of that, we got my DH's semen results back. He has abnormal viscosity, sperm concentration ( < 2; normal is over 15)and motility ( < 1: normal is over 40). 
​I don't feel there's a point in trying anymore. How can we can pregnant with my "old" eggs (+40 day cycles) and no sperm? :'(
