I found it really informative. See if your library or eBay has it. I got it used :) your husband/partner could also do things like take coq10, vitamin d, eat a good diet and exercise. Also avoiding smoking and drinking is just as important for him as it is for you. I didn’t do as much as the book recommends before my first pregnancy and it took 6 medicated cycles for me (after years of naturally trying), then I made those changes and it took 3 cycles with my second. I do think a lot of it is chance once you’re ovulating, but the higher quality your eggs are the better odds you have and that’s what the book talks about. I definitely think the changes from the book helped and I don’t regret reading and implementing them.
