If your family is anything like ours, sunscreen is a routine part of our daily lives. Sunscreens protect our skin from sunlight using mineral or chemical filters. Mineral sunscreens use zinc oxide or titanium dioxide. Most sunscreens use chemical filters that contain active ingredients such as oxybenzone. Studies have demonstrated that these chemical filters mimic hormones and can act as endocrine disrupting chemicals.
Sunscreen exposure increases our exposure to chemical filters, such as oxybenzone. Oxybenzone use is widespread throughout the US. It is detected in nearly every American.
The reproductive system is sensitive to environmental factors. Early pregnancy is a particularly vulnerable time for endocrine disruption. Exposures when trying to conceive can impact the likelihood of conceiving as well as the health of the pregnancy.
Oxybenzone exposure and exposure to related compounds is associated with male infertility and poorer reproductive success in men undergoing fertility treatments. Similarly, men with greater exposure to a similar compound found in sunscreen had poorer sperm quality and took longer to conceive. Female exposures to oxybenzone and related chemicals have been linked to increased risk of endometriosis and problems with ovulation. These chemicals have also been associated with oxidative stress and inflammation in pregnancy.
The good news is that we can be informed consumers and change our exposure.
This is a great resource of safer sunscreen alternatives.
Take home points
- Avoid sunscreens with chemical filters, particularly oxybenzone
- Use mineral sunscreens when possible when trying to conceive
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:
- 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.
- 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.
It is estimated that up to 54% of couples with infertility experience a high level of stress, anxiety, and depression before and/or during fertility treatment. It is incredibly common to need additional help when going through fertility treatment, which is why I encourage the use of complementary stress reduction techniques with my patients. But sometimes yoga, acupuncture, and mediation isn’t enough and more help is needed. The most commonly prescribed antidepressant is a group of medications called selective serotonin reuptake inhibitors (SSRIs).
A recent study compared women on SSRIs going through IVF to women who were not on antidepressants. They found that the embryo health and IVF outcomes did not differ between the groups. This suggests that, from a fertility standpoint, there is no reason to avoid using an antidepressant if you need it.
Fertility treatment is hard enough. There is no reason to suffer through poorly controlled anxiety and/or depression while going through fertility treatment. If you need additional help, please reach out. The best way to have a happy healthy family is to start with a healthy mom before conception. You are not alone.
Take home points:
- The diagnosis and treatment of infertility is stressful
- It’s common to struggle with stress, anxiety, and depression at any phase of treatment
- Antidepressant use does not impact IVF success rate.
- Do not hesitate to get additional help if needed
Phthalates are a group of chemicals found in many types of plastics in a variety of consumer products. We have previously discussed the negative impact of phthalates on fertility. A recent study adds to this: phthalates negatively impact an IVF cycle. Women are disproportionally impacted by phthalate exposure.
In this study, women with high levels of phthalates had fewer eggs at the time of egg retrieval, fewer fertilized eggs, and fewer top quality embryos. This group suggests that DEHP, a specific type of phthalate, may impair early IVF outcomes, specifically targeting the oocyte. If you are thinking of undergoing IVF this year, I encourage you to investigate what you can do to optimize your IVF cycle by limited your exposure to phthalates!
What you can do:
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
Changing your habits is HARD– it’s hard to change what you eat, to make time for regular exercise, and to prioritize your well-being. But it’s absolutely worth it!
So many patients with infertility tell me they feel powerless and hopeless. I want to empower you to believe that there are some things that you can do to boost your fertility. And it starts with taking care of yourself.
Your weight is very important for your health and your fertility. So important that we have discussed it here, here, here, and even here. It’s a recurring topic on the blog because it’s important and it is, unlikely your age, something that you can change.
A study was recently published that the hard work that is needed to lose weight is worth it. Women who consumed fewer calories and started exercising were much more likely to lose weight, ovulate on their own, and get pregnant compared to people who didn’t make these changes. A combination of fewer calories by reducing fat and refined carbohydrate intake, and increased aerobic exercise is the cornerstone of healthy weight loss.
What you can do
- Do something, ANYTHING for exercise 30 minutes, 5 days a week.
- Consider using a fitness tracker or pedometer like FitBit
- Schedule your workouts when nothing will interrupt your session. Make your fitness a priority.
- Take a closer look at your diet and what you can cut out easily. Consider an app like MyFitnessPal.
- Start by eliminating refined carbohydrates found in juices, sodas, and sweets
- Don’t get discouraged. Any step is a step in the right direction.
- Talk to your doctor for more information about local support groups and fitness programs in your area.
We have previously reviewed the negative impact that chemicals in plastics may be having on our health and fertility. One of the best ways that we can reduce this exposure is in our kitchen. When food is stored or heated up in plastic, the dangerous chemicals can leach into the food that we ingest. These chemicals can then interact with our endocrine system and cause disease.
When I first started considering my exposure to plastics, it felt like an impossible uphill battle. By starting in my kitchen, the task of reducing plastic exposure felt more manageable. I started by removing all plastic storage containers and making sure that we do not heat up food in plastic.
Here is a quick article that I thought I would share to help reduce your plastic exposures at home in the kitchen. I hope this helps you find reasonable solutions for limiting your plastic exposure in your home.
