Daylight Savings Time May Lower Chances of IVF Success for Some: Study

At our center, we have long held that your circadian rhythm–how your biology responds to the day-night cycle–impacts your fertility. This is one of the many reasons we focus on optimizing vitamin D levels, melatonin (when necessary) and paying careful attention to our embryo transfer schedules. In case your fertility center hasn’t figured out how important that this is, check out the following recent study on miscarriage risk associated with time shifts.  https://consumer.healthday.com/infertility-information-22/infertility-news-412/daylight-savings-time-may-lower-chances-of-ivf-success-for-some-study-719514.html

More Reason to Eliminate Phthalates from your home: impaired sperm function

We’ve already provided pretty compelling reasons why it is worthwhile to avoid these chemicals with a funny name but now there is even more evidence. A new study has now found that these chemicals can reduce the chance that a man’s sperm will make a healthy embryo. Bottom line is that paying careful attention to your potential exposure risk with both your chances of having a healthy pregnancy and a healthy home to raise your child.

Here are some easy steps that you can take to begin reducing your phthalate level today:

  • Only use nail polishes that are phthalate free—most add a phthalate called DBP to reduce chipping
  • Don’t microwave or cook your food in plastic containers or use plastic utensils to eat hot foods—heat leaches this chemical out of the plastics and into food—the easiest pathway into your body
  • Avoid plastic bottles—seek out glass or metal instead. When you must use plastic seek out bottles with the #2, #4 and #5 in the recycle triangle
  • Avoid perfumes and scented products—phthalates (DEP) are used to prolong fragrances
  • Don’t use air fresheners—most contain phthalates
  • Avoid vinyl containing products—many products like lawn furniture, rain coats or shower curtains can not only release phthalates that can be inhaled but they can also be absorbed through the skin as well.

Are Low-Calorie Sweeteners Making You Fat?

There is a global obesity epidemic. More than one BILLION adults are projected to be obese by 2025. Obesity is a major risk factor for the development of medical conditions such as diabetes and cardiovascular disease, as well as numerous types of cancers. Obesity, in either male or female partners, is associated with a decrease in the ability to become pregnant. Obese women are not only at an increased risk of having trouble conceiving, they are also at risk of: needing medications to conceive, being less responsive to fertility treatments, losing pregnancies to miscarriage, having children with birth defects, as well as having complications during pregnancy such as high blood pressure and diabetes.

 

Many people use artificial sweeteners or “diet” drinks as a substitute for whole ingredients with the hope of cutting calories. A recent study suggests that this may be a bad idea. This group followed people for 10+ years and found that people that used low-calorie sweeteners had a higher body mass index (BMI), larger waist circumference, and were more likely to be obese. This paper suggests that using low-calorie sweeteners may not be effective means of weight control, and might even lead to harm.

 

When I review studies like this, I think it’s important to note that these studies are NOT designed to prove that artificial sweeteners CAUSE obesity; rather, they show an ASSOCIATION at a population level. For me, as a physician and mom, this association is reason enough to be cautious about the use of artificial sweeteners. For others, especially die-hard Diet Coke drinkers, they might want more proof before changing their diet habits.

 

There is no easy solution for weight loss; diet drinks probably aren’t going to help. If you are overweight or obese, don’t lose hope. Even a modest weight loss (10-15% body weight) can enhance your natural fertility. It will take hard work through diet and lifestyle changes. Avoid sugary snacks and drinks in general. Consider using natural sweeteners like stevia (Dr. Greene’s favorite!) or honey (my favorite!) instead of artificial ingredients. Your selection in which sweetener you use, is likely going to depend on what is most important to you including considerations like why you are using a sweetener, why you are looking for artificial sweeteners (cutting calories), and taste. Please be an informed consumer and make sure that you know why you are making the choices that you make. Taking care of yourselves will help prepare you for a healthy pregnancy and prepare you to be healthy parents.

Is YOUR Makeup Speeding Our Journey Toward Menopause? The Scary Association That You Need to Know About

article-2222190-0d0d6ccc00000578-684_634x424

One of the first research projects I did on the impact that lifestyle can have on fertility showed that women exposed to a handful of common chemicals classified as EDCs (endocrine disrupting chemicals) go through menopause earlier than women who have less exposure. It gained a lot of media attention because several of the toxic chemicals I found in my study are common in makeup products. A more recent study highlighted the continued importance of addressing this issue in women’s health and prompted this post.

This group evaluated the top beauty brands for each type of makeup and found 1322 ingredients. They then went on to summarize the evidence suggesting the association between each of these chemicals and menopause. Most of the chemicals they found are absorbed through the skin, meaning that all these chemicals are entering our bodies each day. Although the group admits there aren’t enough studies to show a direct link between cosmetics use and menopause, I think it’s enough to have me question what I’m being exposed to on a daily basis and how it’s going to impact my health.

Even though you may be far from menopause, I think it is still important for you to consider how chemicals that you’re exposed to can be impacting your ovaries. Women who go through menopause early are likely to have a shorter fertility window, meaning that they may use up their eggs at a faster rate than someone else their age. In the fertility world, this can translate to women who respond less to medications or are less successful with their use of assisted reproductive technology compared to others their age.

As a woman, as a mother, and as a fertility specialist, my first response to learning how many chemicals we are exposed to daily was disbelief: Why aren’t we protected as consumers from these potentially toxic chemicals? Why are they still exposing people to these toxic chemicals? Although the Food and Drug Administration monitors the chemicals that go into food and drugs, cosmetics are not subjected to the same regulation. Here are a few things that we can do to protect ourselves by limiting the numbers of chemicals we are exposed to daily.

 

Take home points:

  • Women are exposed to 1000s of toxic environmental chemicals each day.
  • Some of the chemicals found in makeup have been linked to health problems, including earlier menopause
  • Physicians and patients need to do a better job learning about the risks to their health so that they can make more informed choices in selecting their personal care products
  • What you can do:
    • Limit the number of personal care products you use. For example, try to limit to one type of shampoo to minimize the exposure to multiple chemicals.
    • Avoid any personal care items that have fragrances or scents.
    • Read labels and support companies that disclose what their ingredients are and support their efforts to remove those that are not necessary or are suspected to be unsafe.
    • Be an informed consumer: know what you are being exposed to. Here is a list of great resources.

Getting Healthy While Getting Pregnant! Flax Seeds for Hypertension

One of the most important aspects of boosting your chances of becoming pregnant is to optimize blood flow to your pelvis–this is true for both men and women! For women, this is even more important since pregnancy can exacerbate blood pressure problems dramatically. Rather than resort to medications, here’s a great nutritional tip. Introduce 30 grams of ground flax seed into your daily diet–that’s about a 1/4 cup. You can add this to salads, soups, cereals, smoothies or just about anything. Studies now show that this simple intervention can reduce your blood pressure more effectively than many of the popular–and much more expensive–medications. For those of us that love the science and want to see the proof, watch this brief video with links to the supporting studies:  http://nutritionfacts.org/video/flax-seeds-for-hypertension/

 

Sleep Can Affect Male Fertility

The impact of lifestyle upon male fertility is very difficult to study and therefore rarely gets much scrutiny. In previous posts, I have referenced studies on how healthy sleep and melatonin levels impact egg quality. Now we have a new study that found that men that sleep less than 6 hours per night or more than 9 hours per night seem less fertile than those within the 6 to 9 hour time range. Although further research would be needed to confirm the validity of this study, it could be that sleep is impacting your ability to conceive with your partner.

Male Fertility and Diet | NutritionFacts.org

Too often the entire focus of fertility recommendations are directed towards women. It is true that egg quality is the single most important factor in determining conception. That said, a healthy egg cannot overcome sperm with damaged DNA. So, let’s provide some guidance for what men should be doing with their food choices to improve the chance of a successful conception.  http://nutritionfacts.org/video/male-fertility-and-diet/
