7 Tips For Avoiding Chemicals That Can Harm Fertility

Infertility....a condition that has touched far too many friends and family in my life.  Something so many women silently struggle with - a pain that I could never imagine.  I remember the day I decided I wanted to start a family.  The emotions and feelings took me by surprise because I had waited several years to feel this way and now the time was finally right.  We started trying right away and while it took us close to 8 months to conceive - that's nothing compared to what women who face real fertility struggles endure.  The more I learn about environmental health and how harmful and unregulated chemicals can impact our fertility as women (and men!) the more it has become my obligation to share what I have learned over the years with others.


Did you know that...

* Difficulty in conceiving and maintaining a pregnancy affected 40% MORE women in 2002 than in 1982.

* Studies indicate that sperm count and testosterone levels may be declining in US males and environmental exposure to toxic chemicals like BPA and phthalates may play a role in these issues.

* Prenatal exposure to phthalates—chemicals found in personal care products and other consumer products—
can cause the reproductive organs of male infants to develop abnormally.

* Today, girls are entering puberty earlier than they were a generation ago—in part due to childhood and, likely,
in-utero exposures to endocrine disruptors (substances that can alter the body’s hormonal responses).

* Early puberty puts girls at a higher risk for later-life breast cancer, and the shortened childhood undoubtedly has
larger implications, including an increased risk of depression.

* There is growing scientific evidence of the impact of environmental contaminants on declining reproductive
function and increasing rates of reproductive illnesses since the mid-20th century, including difficulty conceiving and maintaining pregnancy, increased rates of testicular cancer, and increased preterm birth.


People planning to conceive should be aware of common chemicals that can affect fertility.

Here, Mark Green, lecturer in reproductive biology in the University of Melbourne School of BioSciences, offers seven ways to play it safe.

In modern life we come into contact with many different chemicals through the products we use, the food we eat, and the air we breathe.

Most of these chemicals cause no harm at the levels we are typically exposed to, but my research and other studies found that a particular group of common chemicals called endocrine-disrupting chemicals, known as EDCs, can affect sperm, egg, and embryo quality and, therefore, a person’s chance of having a baby. They can also affect the potential long-term health of the child.

EDCs occur naturally in the environment and in the food we eat. However, since the Second World War, rapid industrialization has seen the creation and use of thousands of new chemical compounds.Throw out all those old receipts in your wallet or at the bottom of your bag.

These include artificial EDCs used in many common household items. Some of the most common kinds of EDCs you may have already heard of are BPA (Bisphenol A), phthalates, and parabens.

Around 95 percent of us have EDCs in our bodies, but according to a growing number of research studies, people who struggle to conceive have higher levels of some EDCs. We also know that higher levels of some EDCs are associated with a decreased chance of becoming pregnant among couples who use assisted reproductive technologies, like IVF.

As we mark Fertility Week—a national [Australian] public education campaign aimed at helping people improve their chances of becoming pregnant and having a healthy baby—it is important to understand what you can do to reduce your exposure to EDCs, especially if you are thinking about having a baby.

1. Check labels and packages

For some time, we have been told it is important to wash fruit and vegetables because of the chemicals that may have been sprayed on them.

EDCs are often present in these sprays, so washing fresh produce thoroughly can help reduce your consumption of some of these chemicals. EDCs are also present in the material used to coat the inside of food cans, as well as in plastic food packaging. So, wherever possible, it is best to avoid processed or pre-packaged food. Also read the labels on all food products and avoid those with certain additives, preservatives, and antibacterial agents.

Oily fish, including salmon, tuna, sardines, and fatty meats may also contain higher quantities of EDCs, particularly in the fatty part of the animals, depending of where these animals were caught or produced. Limiting how much and how often you eat these types of fish or meat is another way of reducing your intake of EDCs.

2. Be careful how you heat

Plastic takeaway containers, cling wrap, and foil also contain EDCs that are absorbed into food when heated, especially if the food is fatty. So, it is very important not to heat food or put hot food in these soft plastic containers, or cover them with cling wrap or tin foil.

Instead, heat your food in china or glass—and cover your dishes with a paper towel or plate instead.

It is also important to keep in mind that plastic containers which are advertised as “BPA free” may contain other EDCs such BPS (Bisphenol S), which can be just as harmful.

3. Skip soft bottles

EDC-containing plasticizers are used in the manufacturing of drinking water and soft drink plastic bottles. So instead, drink water or soft drinks from glass or hard plastic bottles, rather than soft ones, reducing your intake of these chemicals.

It’s also particularly important to avoid drinking from disposable water bottles which have been sitting in a hot environment, as the water will have absorbed significant levels of EDCs from the plastic.

4. Chuck your receipts

The shiny surface covering many sales receipts contains BPA, so avoid handling these receipts (especially with wet fingers), and throw out all those old copies in your wallet or at the bottom of your bag.

5. Keep the air clean at home

Air fresheners, smoke, strong chemicals, bug sprays, heavily perfumed products, plastic smells and fumes, as well as particles released from house furnishings, all contain potentially harmful EDCs.

Bottom line: if you can smell something then you are being exposed to it.  The best approach is to air your home frequently to reduce your chance of breathing in chemical particles.

6. Clean “green”

Many household products can contain EDCs, including detergents, hand sanitizers, cleaning agents, and carpet cleaners. These chemicals can also be found in glues, paints, and varnishes. As a result, consider reducing your exposure to EDCs by replacing strong household cleaning products with “green” alternatives wherever they are available.

There are now a wide range of “green” cleaning products available in many supermarkets and shops.  When working in the garden, consider avoiding harmful pesticides and herbicides and, if possible, choose “green” gardening products.

7. Don’t slather on parabens

Personal care products like shampoos, conditioners, hair colorings, cosmetics, and body washes can contain EDCs known as parabens. Choosing products free of parabens can help lower your intake of harmful chemicals.

Personal care products without parabens have become increasing available on the supermarket shelves, with clear statements like “paraben free” on the item, so consumers don’t have to spend time deciphering the long list of ingredients.

Simple changes, like the ones here, can make a big difference in decreasing your daily exposure to EDCs. Knowing where harmful chemicals can be found and what you can do to avoid them is the first step towards improving your health and your chances of having a baby.
