I also just bought It Starts With The Egg and I thought it was very interesting. It references all of the scientific studies used to compile the book so you can go and do your own background reading etc. It seems to have very solid scientific foundations, unlike some of the books out there.
I'm waiting to start my first IVF cycle and after finishing this book a couple of days ago I have binned a load of the toiletries and cosmetics I have been using for years and replaced them with organic / natural ones that don't contain nasty chemicals. I'm also gong to change all of my cleaning / laundry products and then look at removing products with BPA's in them from my kitchen (although I did this with my tupperware ages ago anyway - BPA's are scary!). To be honest though, this detoxing my lifestyle thing is been something I've been meaning to do for ages and this has finally given me the push to sort it out. I just think going as natural as possible can't do you any harm.
I've also stopped drinking (the biggest challenge for me!), cut way down on caffeine, and tried to eat organic and low GI when I can. I'm a normal BMI so I'm not restricting calories or anything. And I'm not cutting anything out entirely.
I've been taking a pre-natal vitamin since we began trying but I'm now adding a CoQ10 ubiquinol supplement as it's good for increasing egg quality and that's where my fertility problem lies.
I'm not going to lie and say I'm finding it easy to clean up my lifestyle like this - I love a McDonalds and a cocktail. Plus it costs more money. But I only get one chance at IVF on the NHS in my area so need to give it the best chance. This stuff might not work, but it won't do any harm so I figure I may as well try. Any yes really unhealthy people have babies all the time but fertility has so many factors and if you're already struggling why not try and do what you can to help your body.
I've also been having acupuncture fortnightly for a couple of months now and I'm trying to not stress about stuff too much, which I find hard. I've been doing the odd 10 minute meditation session using the Headspace app. Again, not sure this helps but it can't be doing any harm because it's pretty relaxing.
I hope whatever you choose to do or not do works for you and I wish you lots of luck with your treatment.x
