Book for men about TTC

There's lots and lots of books that women can get to learn about conceiving and their body but I'm not able to find any for men. My hubby likes to think he knows more about my cycles than I do 😂 (he says 'but women get pregnant all the time outside of their fertile week). 😳 No! He needs educating!!! Lol So there should definitely be books for men that goes over these topics! Like even in a funny/light hearted/supportive way. Do you know of any?
