A recent article in the New York Times caught my attention and I thought it would be worth sharing.
In summary: evidence from the CDC suggests that America’s fertility is in precipitous decline.
What you can do:
- Be an informed patient. Know your fertility status to help plan your life and family goals.
- Schedule an appointment with a REI for more information.
Couples often ask me: “What else can we do to make this IVF cycle successful?” The first answer, is to pick the right lab. I’m fortunate to work with an amazing group of embryologists so I encourage my patients to consider the next step: using your diet and lifestyle to stack the odds in your favor. As we have discussed before in the blog, what you eat and what you do can absolutely impact your fertility and overall health. New research demonstrates that your diet, in particular, can impact your success with IVF.
As many of my patients know, I encourage a plant-based diet to enhance your fertility naturally. The problem with many of these studies that we have previously reviewed is that people who eat a plant-based diet are more likely to be thin and the following question emerges: “Is diet really impacting your fertility or does this have to do with your weight?” A new study helps us address this question.
In this study, women who had a normal weight (BMI < 30 kg/m2) underwent IVF in Greece. Women who ate a Mediterranean diet were more likely to get pregnant and bring home a healthy child compared to women who did not eat a Mediterranean diet. Women who ate better were almost 3 times as likely to bring home a child than women who did not eat a Mediterranean diet! The results suggest that dietary modifications may help increase the chances of a successful pregnancy and delivering a live baby for women undergoing IVF treatment.
What this study doesn’t answer, however, is when these dietary changes need to be implemented in order to have the full benefits on your fertility. My advice is simple: the sooner the better. The healthier you are when you start an IVF cycle, the more likely you are to get the full benefits of diet on your fertility. However, if you have a time crunch with regards to your fertility, with diagnoses such as diminished ovarian reserve, it may not be in your best interest to delay starting treatment. Talk to your doctor for more information about what the best next steps are for you.
Take home points:
- Your diet can impact your chance of having success with IVF
- Consider implementing a Mediterranean diet
- Talk to your doctor for more information to help select the best diet for your goals
We have previously discussed in this blog the impact of the beverages we drink on fertility.The old saying of “You are what you eat” couldn’t be more true- what you eat absolutely impacts how we feel and our overall health.
New research is adding to this old saying- what you drink may be just as important as what you eat, when it comes to fertility. Similarly, we also discussed that the beverages you consume now can impact the health of your future children: women that drank beverages with low-calorie sweeteners are more likely to have obese children.
New research adds to these concerns. In this large study, the dietary habits of men and women were evaluated while they tried to conceive. Drinking sugary beverages was associated with decreased fertility for both men and women. Similarly, participants who had consumed the most sugary drinks (>7 servings/week) were found to have the lowest odds of fertility for both men and women.
This study looked at what couples drank during an IVF cycle and monitored their outcomes. They found that couples that drank more sugary drinks like soda did worse in IVF, when compared to couples who don’t drink sugary drinks: fewer eggs and fewer good quality embryos.
Take home points:
- Men and women should avoid sugary drinks when trying to conceive, but particularly if they are using IVF
- Using artificial sweeteners is not necessarily a safe alternative to sugary drinks
- If you can’t completely eliminate sugary drinks, consider limiting your intake to <1 beverage a day.
Many of the supplements that we recommend for our patients to use are based upon theory or observational studies. That’s why when we have additional research to support a recommendation; it creates even more excitement and promise. That’s how we currently feel about inositol.
Inositol is a naturally occurring vitamin-like chemical that is common in fruit. It occurs in two forms; myoinositol and its alternate form D-chiro-inositol. It is not considered a vitamin because your body is capable of making this vitamin B-like substance. Unfortunately, some women might not make enough to insure the health of their immature eggs. Disappointingly, studies suggest egg quality correlates with the presence of this important substance.
Inositol has been classified as an insulin sensitizing agent like metformin. Also like metformin, it has been shown to have other important effects that seem to benefit outcomes for women undergoing fertility. Additionally, inositol improves responsiveness of the immature follicle (developing egg and its hormonal support team) to the hormone FSH for women going through IVF.
A recent review of studies performed on women taking this supplement during IVF treatment suggested that there may be several other benefits. They found that the women with a predicted low response required less medication to stimulate their ovaries if they were on this supplement. More importantly, they appeared to produce higher quality embryos and had a higher pregnancy rate.
As a note of caution, since this supplement seems to have similar actions to metformin—it is not recommended to use both during the same treatment cycle. This information seems very reassuring that women that have not tolerated metformin or choose not to take that medication—a supplement containing both myoinositol and D-chiro-inositol may provide some (or possibly all) of the same benefits.

At the initial patient visit, I try to learn about any special dietary restrictions my patients may have. A common diet is going “low carb” in an effort to lose weight. Emerging research, however, suggests that this could be dangerous when trying to conceive.
Folic acid is a vitamin that reduces the risk of having a child with a problem with it’s spinal cord, known as a neural tube defect. Folic acid is added to many common meals, like cereal, in order to fortify the food. Women who intentionally avoid carbohydrates, thereby consuming fewer fortified foods, may not have adequate dietary intake of folic acid.
This study found that women eating low carb had significantly lower dietary intake of folic acid. Women eating low carb were 30% more likely to have an infant with a severe neural tube defect such as anencephaly or spina bifida.
What you should do:
- Talk to your doctor about any special diets you have before trying to conceive
- Women should take a daily prenatal vitamin in addition to having a well-balanced diet while trying to conceive
A common question asked in a new fertility evaluation is: “Which prenatal vitamin is best?” We have previously tried to provide some guidance in choosing the best vitamin. The ingredient list in your prenatal vitamin needs to be considered.
In particular, iodine is an often-overlooked but extremely important component that should be considered in a prenatal vitamin. Iodine is a mineral used by the body to regulate metabolism; it is also very important for brain development in children. It is often found in seafood, iodized salt, dairy, and some fruits and vegetables.
A new study shows that women who have low iodine levels take longer to get pregnant than women who have normal iodine levels.
Take home points:
- Iodine is important in pregnancy and when you are trying to conceive
- Boost your fertility naturally with iodine
- Make sure you are on a good prenatal vitamin
- Talk to your doctor about what levels of iodine are best for you
Typically, my blog posts are about sharing the latest research studies or insights into some treatment options or they focus on busting a popular myth. However, every now and then I have an opportunity to introduce someone that I feel has something very important to say. This is one of those posts.
I want to introduce you someone that I consider a true hero. Amber has been through fertility treatment. What makes her someone that I admire is her desire to help others on the same path. In her blog: https://miraclestakealittletime.com/posts/ she very eloquently shares her own experience. But she even goes one step further. She offers support to others beyond the information and experience of her journey.
If you need to reach out to someone, she is an articulate and engaging woman willing to provide you with some insights: https://miraclestakealittletime.com/contact/ . You are not alone.
