At a recent trip to Target, I realized just how many things are labeled as “antibacterial.” But what is antibacterial, anyways? And why do we need it?
“Somehow, through marketing or misinformation, we’ve been led to believe that if we get rid of bacteria, we’ll improve our lives and our health. In fact, the opposite is probably true” –Dr. Martin Blaser In fact, to date, there is no evidence that washing your body and home with antibacterial products does any good compared to old fashioned soap, water, and scrubbing!
Triclosan is an anti-bacterial compound added to personal care products like soaps but it is also added to plastics found in toys and medical devices. Triclosan is so common that the majority of people in the US population are exposed to this chemical; triclosan exposure is real and widespread.
Breaking news this week reveals that triclosan may target the ovary and make it harder for a woman to conceive. This group investigated whether ovarian reserve, a marker of how many eggs a woman has and how she might respond to fertility treatment, was different in women with high levels of exposure compared to those with lower levels of exposure. They found that antral follicle count, a marker of ovarian reserve, decreased as the triclosan levels increased. Perhaps even more concerning was that this relationship became even stronger in lean and young women, suggesting that this may contribute to reduced natural fertility and could lead to a need for fertility treatment at a younger age.
Other studies have found similar concerning results: women with higher levels of triclosan exposure take longer to conceive when compared to women with lower levels of this chemical. Triclosan is also associated with lower oocyte yield in couples undergoing IVF. Similarly, triclosan has been found to disrupt implantation of a pregnancy and alter placental function, leading to pregnancy complications in animal models.
The good news is that the FDA is banning the use of triclosan in antibacterial soaps, effective next month (September 2017). Way to go FDA! Thank you! Unfortunately, manufacturers can still add this chemical to dish soaps and toothpaste.
What you can do:
- Reduce your exposure. Avoid purchasing anything labeled “antibacterial”.
- Use bar soap and water, instead of hand-sanitizers.
- Avoid toothpastes that include triclosan, such as Colgate Toothpaste

One of the best parts of my job, is getting to know individuals and hearing their “story.” I love learning about occupations, interests, and their goals for a family. I spend a lot of time listening to my patients so that I can fully grasp all that my patients have been through leading up to their visit with me.
I have to be honest: I’m saddened by how hard my patients are on themselves. There is so much unnecessary blame and justifying in fertility. For example, a common thing I hear can be something like the following: “I love coffee, but after trying to conceive for so long I gave it up. I miss it but I’m willing to give up anything in order to prove that I’m ready for a family.” Does this sound familiar to you? First off, you can drink coffee. Secondly, please try to be kind to yourself.
Research suggests that kindness and mindfulness will not only help you cope with fertility struggles, but may even improve your outcomes. Unfortunately, this important step is often overlooked in many fertility clinics. I try to address the potential benefits these practices may have with my patients.
As a self-diagnosed perfectionist, I will be the first to admit that I have very high expectations that I set for myself. When I fail to meet a certain goal that I’ve set for myself as a physician or a mom, I beat myself up about it. My advice to you: try kindness instead. Pretend a friend told you the exact same story. How would you react to your friends’ tribulations?
Life is stressful and that won’t change, even once you get pregnant. We can’t control the stressors in our life but we CAN control how we react to them. So please, consider being kind to yourselves and help me support you through this fertility journey.
“If the benefits of better diet came in a pill, it would be hailed as a medical miracle.”
I spend a portion of each new patient visit evaluating diet and lifestyle. Since I started asking, I’ve been surprised by how many patients have confided in me that they are willing to try something new and want to change. I believe that as your doctor, I have the responsibility to share with you the evidence that diet and lifestyle absolutely can work for or against you in terms of fertility. I also believe that one of the most important parts of my job is helping families become the healthiest they can be BEFORE conceiving.
I want to be honest. I’m not perfect and I would never pretend to be. My family members love meat- including (gasp!) hot dogs! Being vegetarian is challenging, especially when kids and working parents are involved. I get it. My goal is to make my family as plant -based as is reasonable. I hope that it will work, but I also recognize that the benefits of a plant-based diet are not “all or nothing.” Any change is a step in the right direction. And I absolutely will not shame or judge you if this doesn’t work for your family. With that, I encourage you to consider learning more about plant-based diets and whether it might be something you would be willing to try. It can’t hurt, but it may help enhance your fertility naturally and reduce your risk of a number of medical problems.
If you are interested in learning more, here are a few links to evidence-based resources that sold me on plant-based.
I would love to hear from you. What is the biggest challenge in your family that prevents you from going plant-based? Have you tried being vegetarian? What worked? What didn’t? What are your favorite plant-based meals to help convince my family?
I spend a significant amount of time with each of my patients reviewing their lifestyle and dietary habits. Ultimately, we all have the same goal: happy healthy families. I strongly believe that part of my job as a reproductive endocrinologist and infertility physician is helping build healthier families. As I reviewed in previous posts, we believe that our habits before and during pregnancy can program many diseases in childhood and later in life.
I previously discussed the importance of whole grain diet as it relates to fertility. New research suggests yet another reason why you should consider whole grains, and stick with it throughout a pregnancy. Researchers found that children born to women with gestational diabetes who consumed the most refined grain (more than 156 grams per day) were twice as likely to be obese at age 7, compared to children born to women with gestational diabetes who ate the least amount of refined grain (less than 37 grams per day).
Take home point: eating refined carbs in pregnancy could increase the risk of your child being obese at a young age. “You are what you eat” … and based on this study, your future child will be too.
What you can do:
- Substitute one meal a day for something with more whole grains.
My neighborhood pools opened this week for summer and my family couldn’t be more excited. Unfortunately, mosquitos are popping up again and reminding me of the importance of discussing insect repellants with my friends, families, and patients.
Many women who never wear insect repellants have recently become interested in these products because of the news coverage of the Zika virus. The Zika virus was introduced to the world during the most recent Olympic games in Brazil. Mosquito bites were linked to severe birth defects and the Zika virus was identified.
The number of pregnant women with laboratory evidence of possible recent Zika virus infection and the number of fetuses/infants with Zika virus–associated birth defects continues to increase in the United States. About 1000 pregnant women in the US were diagnosed with Zika virus infection last year. Of these pregnancies, birth defects were reported in 15%. Congenital microcephaly, or severely small head in the affected child, has been a hallmark of intrauterine infection with Zika virus. However, the full clinical spectrum and severity of Zika remains unknown. Others have recently reported much lower rates of confirmed Zika virus in other parts of the US and no confirmed fetal or neonatal infections, which puts some doubt on the true prevalence of this widely publicized virus. The field of perinatal Zika virus infection is evolving and we continue to learn more about the virus as well as the risk of disease.
Insect repellants can be a good option for reducing your exposure to mosquitos and tics. The EWG has published excellent resources for consumers to learn about what is in their bug repellent.
My family uses DEET. It protects you against tics and mosquitos. DEET is the only insect repellant that has been tested on pregnancy women. The children of mothers who used DEET in their second and third trimesters showed no birth defects, changes in body size or developmental problems. No studies have examined the children of women who applied DEET during their first trimester. However, at toxic doses, DEET has been associated with seizures and neurological damage. Although this risk is scary, The EPA reports that this risk is very low- 1 per every 100 million persons. As with medications, I tend to recommend limiting the use of multiple products in order to limit exposure to multiple chemicals. Choose one insect repellant and stick with it.
A more natural alternative is also available as oil of lemon eucalyptus. The tree extract is refined to intensify the concentration of the naturally occurring substance para-menthane-3,8-diol (PMD) from 1 to 65 percent. The resulting oil is very different from unprocessed tree oil. Some testing shows that concentrations of 20 to 26 percent PMD may perform as well as 15 to 20 percent DEET against both mosquitoes and ticks (Barnard 2004, Consumer Reports 2010). I think it is important for us to recognize the limited safety data available on essential oils in pregnancy and in children. Refined oil of lemon is classified as a possible biochemical pesticide. Oil of lemon eucalyptus and essential oils have disadvantages but is a good choice for people who want a botanically based bug repellant. EWG recommends that consumers who are in high-risk areas for bug-borne disease or need long-lasting, effective bug protection avoid botanically-based bug repellents, aside from Oil of Lemon Eucalyptus. In other cases, you may find it worth your while to try botanical repellents to identify one that works well for you.
What you can do:
- Avoid exposure to mosquitos: use insect repellants with <50% DEET when trying to conceive and during pregnancy. More is not better. My family uses 30%.
- Wash your hands well after applying insect repellant. Wash repellant-coated skin at the end of each day.
- You and your partner should avoid travel to areas with Zika virus when trying to conceive and during pregnancy. Discuss your travel plans with a physician if there is any question about the safety of travel. Talk to your physician if you or your partner are concerned that you have been exposed to the Zika virus.

The terrifying association between consumer products and health problems is described in this recent article found in Time Magazine. Wow. What a headline. This article was written as a result of a large lawsuit for baby powder being associated with ovarian cancer. Yep, you read that right.
I’ll leave the rest of the reading up to you if you are interested but just had to share one more quote from the article:
“But it’s actually not surprising. The fact is, many personal care products on store shelves—products we lather in our hair, rub on our skin, and put in our babies’ bathtubs—contain chemicals with known links to health problems, with no warnings at all to consumers.
Many of us assume the companies are using the latest science as a guide to choose the safest ingredients, especially for products used on babies.
We should be able to expect that.
Unfortunately, nobody is watching the store. Companies in the U.S. are allowed to put ingredients into personal care products with no required safety testing, and without disclosing all the ingredients.”
What you can do:
- Keep reading our blog to stay current .
- Be an informed consumer
- Check out the Environmental Working Group to check the safety of the products you already use.
- I use this website every time I need to buy a new product so that eventually I will only have the safest products in my house and in my life. For example, I needed to re-stock on hand soap this week and used the EWG app to ensure I purchased the best rated kind.
I know- whole grains take some getting used to. New IVF data, however, suggests that you should hear me out and give that whole grain bagel and pasta a try.
In a recent study, investigators took a very close look at the dietary habits of people undergoing fertility treatments. Women who ate more whole grains (>52.4 g/day) had higher pregnancy rates than women who ate less whole grains. We have mentioned this whole grain study in our blog before: at least one serving of whole grains per day boosts the odds of success by 33%! It may even benefit women who have problems developing the lining in their uterus (endometrial lining): increasing whole grain intake by 1 serving a day was associated with an increase in endometrial thickness!
What you can do:
- Make the healthier choice: substitute one meal a day for something with more whole grains
