Updates on BPA

bpa-bps-infographic

Bisphenol A (BPA) is commonly found in plastics and the majority of us are exposed to this hormone disruptor multiple times daily. We previously introduced BPA and the negative health impacts here. We know that BPA exposure when trying to conceive can negatively impact multiple aspects of your health, including your fertility and the likelihood of your children having health problems.

New basic science research is adding to our previous concerns about this endocrine disrupting chemical:

  1. BPA negatively impacts how an egg matures and egg quality by increasing DNA damage and oxidative stress. This study also shows the potential for the damage that BPA causes for mom to impact her future children.
  2. BPA can decrease sperm count in males and lead to neurodevelopment problems in their children. This study also was associated with increased obesity in female offspring.

What you can do:

  • Switch to BPA free drinking bottles like those with a #5 stamped on them or use either glass or metal instead;
  • Purchase soups and foods packaged in cardboard cartons or glass instead of the plastic lined cans;
  • Hand wash plastic dishware with mild soap in warm water instead of using dishwashers for these products;
  • Don’t place plastic ware in microwave ovens to warm;
  • Express your support to companies that are voluntarily phasing out the use of BPA in their products.

IVF might not be enough

I am incredibly proud to work at a REI clinic that has the highest live birth rate in the country. A recent study, however, suggests that IVF may not be enough. Lifestyle and the environment can impact your IVF success rates, even at a top notch REI clinic.

In this study, levels of pesticides and common pollutants were measured in the fluid that was obtained from the ovary during an egg retrieval. They found that higher levels of Pretilachlor, β-cyfluthrin, PCB 28 and 180 was associated with fewer eggs at retrieval, lower fertilization rates, and impaired embryo development. They also found that high PCB and pesticide concentrations negatively affected embryological outcomes. This study provides evidence that these harmful chemicals are found in the fluid surrounding individual eggs and are associated with decreased success with IVF. This suggests that if you want the very best chances of success with IVF, you should consider optimizing your lifestyle to minimize exposure to these harmful chemicals.

 

What you can do:

  • Learn how to minimize your exposure to PCBs and pesticides
  • Make a plan to optimize your health before you invest in an IVF cycle
  • Talk to your doctor about a timeline for implementing these changes

Great resource

I spend a considerable amount of time working with my patients to prepare them for a healthy pregnancy.  Lifestyle modifications like small changes to your diet and environment can absolutely optimize your chances of conceiving, regardless of what kind of treatment you are undergoing. This blog is dedicated to exploring the research behind our recommendations to couples.

I want to share an additional helpful resource to those of you who are trying to initiate these lifestyle changes. This group helps you tackle lifestyle changes, one room at a time in a user friendly and interactive manner. Check them out!

 

 

 

 

Organic Food and your Fertility

Has anyone else noticed that just about everything is available now as “organic?!” Should we buy organic everything? I mean, Oreo’s?! How is that even an option? Is buying organic worth it?

1509574257866

Organic food refers to food produced with limited pesticides, fertilizers, and additives. Organic foods tend to be higher in vitamins, minerals, and anti-oxidant content compared to conventionally grown food. Conventionally produced food is associated with higher rates of various cancers compared to organic foods.

 

Organic food is usually more expensive than conventionally produced food. But is the cost worth it?

 

A recent study evaluated pesticide exposure in couples going to a fertility clinic. They found that the more pesticides a couple consumed, the less likely they were to get pregnant and bring home a healthy child. This finding was dose dependent: women with the highest pesticide exposure had the lowest pregnancy rates.  This was true even though the couples were going through fertility treatments. This suggests that dietary pesticide exposure can be associated with difficulty conceiving.

 

Switching to organic products can also reduce your exposure to hormone disrupting chemicals and support beneficial practices for our environment.

 

What you can do:

  • Buy organic produce whenever possible. Some products are more worth the cost than others. Consider being selectively organic to keep your budget on track.
  • Just because something is labeled as “organic” doesn’t mean it’s healthy. Organic junk food is still junk food.
  • Buying organic doesn’t fix everything. Organic food has just as many calories as conventional food. And buying organic is healthy, but should not be used as a substitute for going to the gym.

Reduce your risk of autism with a vitamin!

My goal as a REI is to help provide patients with the information they need to not only boost their natural fertility, but also to help them have a healthy pregnancy and to, ultimately, bring home a happy healthy kiddo. Those of you who know a family affected by autism, know how terrifying the condition can be. Autism is a neurodevelopmental disorder characterized by impaired social interaction, impaired verbal and non-verbal communication, and restricted and repetitive behavior.

Autism is thought to develop during pregnancy. Many neurodevelopmental disorders, like problems with the baby’s spinal cord, are known to be impacted by maternal nutrition during pregnancy. New research suggests that what mom eats during her pregnancy may alter the risk of her child developing autism.

In this large study of over 270,000 mother-child pairs, women were screened for vitamin use and their children were followed to see if they developed autism throughout childhood. Maternal multivitamin use with or without additional iron or folic acid, or both was associated with lower odds of having an autistic child with intellectual disability in the child compared with mothers who did not use multivitamins, iron, and folic acid (odds ratio 0.69).  This study suggests that maternal multivitamin supplementation during pregnancy may be something women can do to decrease their risk of having a child with autism.

 

What you can do:

  • Take a prenatal vitamin when you are trying to conceive and throughout your pregnancy

You are what you drink

Anyone who has met me in clinic or has read this blog knows that I firmly believe that our diet and environment impact our health. 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.

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: fewer eggs and fewer good quality embryos.

The good news is that no associations were found between consumption of coffee or caffeine and IVF outcome. As we have posted before, caffeine gets a bad reputation without cause when it comes to fertility. Similarly, some of the decaffeinated beverages may actually be more dangerous than the caffeine itself. If you are interested in reading more about the risks associated with decaf, please check this link out.

 

Take home points:

  • What you drink matters in terms of fertility, especially during an IVF cycle
  • Avoid sugary drinks, especially during an IVF cycle
  • It’s ok to keep drinking moderate amounts of caffeine during an IVF cycle

Could unexplained infertility be explained by your diet?

unexplained-infertility

Unexplained infertility is a frustrating diagnosis and 15% of couples are affected by unexplained infertility. It means that despite undergoing all the costly evaluations, we don’t know why you are having trouble getting pregnant. Many cases of unexplained infertility are probably caused by the presence of multiple subtle factors, each of which on their own do not significantly reduce fertility, but reduce the pregnancy rate when combined.

 

Research is now suggesting that your nutrition could be a potential reason for unexplained infertility. A recent study compared women who had the diagnosis of unexplained infertility to women who conceived naturally. They found that women with unexplained infertility had significant abnormalities in their dietary habits. These differences ranged from minor imbalances in micronutrients to severe combined macronutrient and micronutrient imbalances. This study suggests that paying attention to your diet could potentially cure cases of unexplained infertility, improve IVF treatment, and even restore natural fertility.

 

What you can do:

  • Take a daily prenatal vitamin to help your micronutrient balance
  • Eat a well-balanced meal when trying to conceive
    • Consider talking to a nutritionist for formal recommendations about your diet if you are concerned you may have an imbalance in your macronutrients
