My husbands fertility as well as mine

So my husband and I have been trying for a baby since we lost our first in April. He recently went to the doctors and got labs done and they told him his testosterone is 265 which is low.. We want a baby badly but no such luck.. I also have insulin induced PCOS so it could definitely be on my part too. I had the gastric sleeve surgery done almost 5 months ago which my doctor told me it was safe to try.. So could someone give us some tips that might help? ❤️ Thank you in advance
