Low T and TTC

So my now fiance and I have been TTC for a while now, I recently got off bc and it took 60 days for me to finally get my first period since I've been off of them. My period started Monday (july 27) but he has low t, and takes the shot once every week. Has anyone had any children with a man who is on the shots or has anyone heard of a way to naturally boost testosterone so we can have our first child. Any info. Would help tremendously!
