Should men take supplements for better sperm quality?

My husband and I decided we wanted to start trying soon. He looked into what a couple should do, and one article suggested he start supplements. He found “the best of the best” mens fertility supplements. Is this necessary? Will it help? Any one else’s husband do this? It says to take them 3-6 months BEFORE trying and he wants to do just that. As well as fish oil. I never heard of men doing that. He also found I should start taking prenatals about 2-3 months before trying. So we are essentially going to be taking these supplements for the next 3 months and then start trying. Just wanna hear what others think! I’m glad he’s being proactive and healthy.. I just hope he isn’t just getting scammed into buying these $50/month supplements from Beli Baby. Lol

I attached photos of what he’s buying
