Been TTC for 16 months since I got married.
Just wanted to add that your DH should see a urologist with a specialty in fertility. Some conditions due to male infertility can be treated and make his situation a little better. Your best chance is IVF but having the best sperm to start with is going to up your success with IVF. Some doctors will swear ICSI can solve everything but not in every cycle. My 3rd cycle was sucessful and I believe part of that had to do with the varicocelectomy ( the removal of a varicose vein in his testicle,
Just my 2 cents.

Definitely shop around for the best clinic that you are comfortable.
