Do an internet search on improving egg quality, and you'll find all sorts of information - some of it good, some of it crap. But how do you know which is which? Much of what you'll find is based off of anecdotal reports ("I drank tincture of mouse urine steeped with bay leaves every day for a month and I got pregnant!") but there is some hard science out there. There's not a LOT of hard science out there, but there are more and more studies that are popping up that at least can give a girl a little bit of guidance.
I'd been thinking about a lot this week about the supplements I should be taking. But then two things made me realize I was missing a huge piece of the picture. The first was a conversation I had with a patient today, a patient who has infertility that is likely due to a pituitary tumor causing low FSH, LH and estradiol levels. She is also slender, and we were talking about why her gyn had thought the problem was her weight. I explained to her how being underweight can cause a woman to stop having periods. "Reproduction is not essential for survival, so if your body is being starved, or thinks it's being starved, it will stop ovulating, and you'll stop having periods."
And the obvious suddenly became clear - my diet is likely part of the problem. Now there's no way my body thinks that I'm being starved, but I'm certainly not giving it the nutrition that I need to make good quality eggs. I've done a decent job of cutting out fast food, but refined carbohydrates have been my best friend the past few months. Especially this past week (candy corn, anyone?) - I'm not eating anywhere near as healthy as I could be eating.
Of course, we all know incredibly unhealthy women who follow horrible diets that get pregnant naturally...but most of them aren't 41 years old. And none of them are me.
When I first started to think about getting pregnant on my own I read The Fertility Diet. It's a wonderful and easy to read book, and there's a great summary here. To be clear, this is a retrospective study that looked at the effect women's diet had on their fertility. It did not look to see if changes in diet would affect the chances of an infertile women getting pregnant. Instead, it asked the question, does diet influence your chances of infertility?
Not surprisingly, the answer was yes. A diet high in simple carbs, high in trans fats and high in animal proteins increased the chance of infertility, while a diet rich in complex carbs, monounsaturated fats and plant proteins increased fertility. Huh. The same things that increase your risk of diabetes and heart disease increase your risk of infertility. The body is an amazing thing.
And then a friend shared these recent studies presented at the American Society of Reproductive Medicine's annual meeting - there's a summary here, and a summary with comment from the experts here. In the first study, women were asked to give a dietary recall before starting IVF. The women who had high protein diets had more blastocysts make it to day 5 and has significantly higher pregnancy rates. The second study actually had 12 women who had prior failed IVF cycles change their diet. They were instructed to increase their protein intake from around 15% of their daily food intake to about 27% of their daily intake for 2 months before their next IVF cycle. This resulted in an increase in pregnancy rates from 16% to 81%. I could only find blurbs about the study, and not an abstract, so I don't know the details - especially if these women were increasing protein intake using animal protein, or if they were using plant protein. And it's a small study. But it is incredibly compelling.
I find myself inspired. Inspired to completely revamp my diet. To cut out refined carbs. To increase the protein in my diet - from beans and lean meats primarily. To increase the healthy fats and cut out as many saturated fats as I can. To eat healthy. To be healthy.
I've felt horrible all week with a headache and a cold. And it's candy corn season. I've felt like crap and I've eaten like crap. But starting Monday that's all over. Finn and I are going grocery shopping and stocking up on all healthy stuff. And the stash of Halloween candy I've been keeping at home is going to the office.
It's going to be hard. Thanksgiving is soon, and so is Christmas. There will be temptations every where, every day. I will cheat. I'm giving myself permission to do so without guilt, simply because I know that when I do cheat, I'm going to make it count, and it won't be often.
I'm doing this to improve my chances of having another child. And I can do anything if it means I'm more likely to achieve that goal.
