TTC Advice

So my bf and I have been together for 2 years he’s older and we’ve been trying for a little over a year. So he thinks since he’s in the military that they messed him up down there with all the different types of shots, so I finally said okay let’s go to the doctor, so he goes finds out he has a low court and low motility, so he’s sad and thinks I’m going to break up with him because he can’t give me a baby! But is there anyone that can help me to try and figure out what he can do to help him?
