Ttc help!

So we’ve been trying for a year now and went to the Gp, I’ve started having my blood tests, just got one more at the end of my cycle. My partner also had a sperm analysis done, we got the results and they want him to do another in 2/3 month as it came back really low. They want to do another to check it wasn’t a one off. My question is has anyone else’s partners sperm come back low and the second time it been ok ??

We already have 1 child that we conceived on the first try so it’s a bit odd we’re struggling now :(

Also if he does truly have a really low count what happens next? What are our options and what can we do? We don’t know much about the process of it all
