Low sperm count, myself fertile! A year TTC! Advice!!

Me and my boyfriend have been trying to conceive for a long while, and have been going through testing because I have two living children and many losses prior to him. Well my fertility testing came back clear, but today we got his results. Low sperm count. They’re sending him for retest after 72 hour abstinence to see if it’s just because of sex too often. But I can’t help feeling angry. Not at him obviously. But so many men go around leaving children they don’t care for in their wake. I myself had my first two in very bad situations with their fathers. But my partner now is a wonderful man who’s taken on two stepchildren as his own. He is an amazing father to a daughter who isn’t his own and stepfather to a son who isn’t his, who also has an involved dad. It makes me so angry, and I know he’s struggling with it too. I think his male ego is bruised. I don’t know what I’m looking for, and I know it’s 2018 and there’s many options, but ohip only covers so much. Fertility treatments can run into the thousands and while we’re financially stable, we’re not super extra comfortable. I guess I just needed a little support, and I love this community. Or even advice. I know there’s vitamins and herbs he can try, I just don’t know which, and advice in upping sperm count is so conflicting online. We’ve done everything possible to track fertility and attempt conception at the optimal time. What can we do, ourselves, to increase fertility? And how do I get over this anger. I know a lot of people struggle, more than we do, and I should be grateful for the children I do have. But I love this man. He is everything I could’ve asked for. I want to be able to give him this. I have never felt so bitter:(
