Fight Oxidative Stress
The effects of alcohol, smoking and pollutants on women’s fertility
We all know that the excessive intake of alcohol, smoking and environmental pollutants are bad for our health, but can they negatively impact a woman’s chances of getting pregnant? The answer is a resounding (and unsurprising) yes! Here’s why – Firstly, as toxicants, they cause our bodies to produce Reactive Oxygen Species or ROS, which are highly-reactive ions and molecules that contain oxygen. ROS are a lot like free radicals, and they are both known to wreak havoc in our bodies by damaging proteins and impairing their function.
Usually, our bodies are able to neutralise the harmful effects of ROS and free radicals with antioxidants. However, when an imbalance in the production of ROS and free radicals occurs, our bodies are unable to cope. As a result, our bodies undergo what’s called – oxidative stress. Oxidative stress is a physiological condition that’s linked to a variety of health issues, including neurodegenerative disorders such as Alzheimer’s disease; cancer; heart problems; blood vessel, gut and vision disorders; lung conditions; chronic fatigue syndrome; kidney, autoimmune, arthritis and inflammatory disease; diabetes; pancreatitis and more.
There is also mounting evidence on the negative effects of oxidative stress on male subfertility, including decreased sperm motility and numbers. And now, findings indicate that oxidative stress can increase the risk for female infertility, as well as delaying pregnancies and lowering pregnancy rates. It can even lead to pregnancy complications like preeclampsia and even miscarriage.
While the field is currently understudied and there is so much more to discover, there is no denying that it is crucial for us to gain a better understanding of how to combat oxidative stress. “If we can identify factors that can be modified to decrease oxidative stress in women, it may be an inexpensive and non-invasive treatment for infertility,” states a study called The Impact of oxidative stress on female fertility by Elizabeth H. Ruder, Terryl J. Hartman, and Marlene B. Goldmanc.
But does this mean we have to play the waiting game for more research to be conducted on the subject? While it may be a few years time before scientists can identify the factors that can be modified to fight oxidative stress, there are steps you can take right now.
We know that oxidation occurs when we’re exposed to toxins, chemicals and stress. Therefore, it would be highly beneficial for you to minimise your exposure to triggers that are present in your lifestyle, foods and environment. Numerous studies have also shown the benefits of a healthy and varied diet, which is supplemented with multivitamins and antioxidants.
In addition, you can maintain your reproductive health by limiting caffeine and alcohol intake, quitting cigarettes, getting adequate exercise, learning ways to manage daily stress and maintaining a healthy body weight. By taking these steps and making crucial lifestyle changes, you can significantly enhance your fertility and boost your chances of conception. Not sure where to begin? Don’t hesitate to speak to a healthcare professional to get on the right track.
How a fathers’ lifestyle influences the health of future generations
We all know that a woman who is trying to conceive should eat a healthier and more nutritious diet. In addition, she should abstain from drugs, alcohol and cigarettes. This is because these factors can affect her chances of becoming pregnant, as well as have a negative effect on her developing fetus should she fall pregnant. Even a woman’ level of emotional stress could influence her fertility and pregnancy success. But does the same apply to men? How does a man’s lifestyle affect conception and the health of his offspring?
Unlike women, men’s reproductive health is under-emphasised and men are largely left out of pre-conception planning. This is despite the fact that male infertility is on the rise, with lower sperm counts and damaged sperm becoming more prevalent. Now, however, new studies are beginning to show that a father’s lifestyle can impact the possibility of pregnancy, as well as the long-term health of his children.
More than genes
Though the saying goes, “It’s all in genes,” scientists have discovered there’s more to our genetic inheritance than that. Beyond our DNA code is epigenetics, which can be defined as, “a heritable layer of biochemical information associated with DNA, and transmitted via the sperm and egg.”
According to Sarah Kimmins, PhD, who holds a Canada Research Chair in Epigenetics, Reproduction and Development and is an Associate Professor at McGill University, Montreal, “We are now beginning to understand that sperm epigenome contains a lifetime memory of paternal experiences. Everything is a man’s daily lifestyle, including his environment, diet, exercise, alcohol and smoking have the potential to disrupt (or support) the setting of the sperm epigenome, which is then passed on to future generations.”
Danger of chemicals
Besides lifestyle, says Kimmins, other factors that can contribute to male infertility are “Chronic conditions like obesity, cardiovascular disease and metabolic disorders, as well as paternal age and heightened stress.” Furthermore, the researchers at McGill University also believe that, “Reduced fertility may be in part attributable to the dramatic increases in chemical production and consequent human exposure.”
Their studies show that there are now about 80,000 chemicals registered for commercial use. We are exposed to these chemicals daily, be it at work, in household products, in the environment, as well as food and cosmetics. As an alarming result, high levels of common toxicants, like bisphenol A and phthalates can now be detected in urine and blood analysis of not just adults, but children too.
While only a handful of research groups worldwide are addressing the cause and effect of lifestyle and chemical exposure to human infertility and epigenetic inheritance, it is becoming increasingly that a father’s way of life plays a vital role in determining his child’s development and health. As such, Kimmins suggests that, “Men should become more involved in pre-conception planning and young men must be educated that their choices today may influence health beyond their own.”
