The importance of micro-nutrients to conception
The adage goes, “You are what you eat,” and the same is true for fertility. But when you’re trying to conceive, you want to rely on much more than just an old saying. Statistics show that around 11% to 20% of couples experience subfertility. Of this, 10% can be classified as unexplained infertility, while 60% are classified as anovulatory subfertility. In my experience, couples today also find their infertility issues compounded by their hectic lifestyles.
Factors such as stress; unhealthy body weight; excessive smoking, alcohol and caffeine intake; exposure to toxins, as well as recreational drug use, can all play a role in affecting fertility. But even those who maintain a healthy weight, manage their stress and abstain from unhealthy habits may neglect a very important factor – nutrition. Fortunately, there is now hard evidence in the form of scientific proof that shows you can indeed improve your fertility by eating right, particularly by including micro-nutrients in your daily diet.
While macro-nutrients, like protein, unsaturated fats and carbohydrates can be easily obtained from the foods that you eat, micro-nutrients like vitamins, minerals and trace elements are often left out due to an unbalanced and unhealthy diet. Realising that micro-nutrient deficiencies are not uncommon in women of reproductive age, Dr Rina Agrawal, a consultant and associate professor in reproductive medicine and obstetrics/gynaecology at the University Hospital at Warwick University, conducted a study on the role of micro-nutrients in improving pregnancy rates.
The study, which involved 58 suitable candidates consisting of subfertile women with an average age of 32.3 years (range 19–40), investigated whether subfertile women undergoing ovulation induction using standard treatment regimens have higher pregnancy rates when given multiple micro-nutrient (MMN) nutritional supplements, as compared with folic acid alone. The findings of the pilot study unveiled that the women on MMN supplementation had a higher pregnancy rate of 66.7%, as compared with 39.3% for those on just folic acid.
This therefore suggests that additional MMN supplementations, such as vitamins B6, B12, folates, vitamin E, multivitamins, iron, zinc, copper and selenium, does improve female fertility. In addition to finding that the women on MMN supplementation had a higher chance of pregnancy compared to their peers, the women on MMN supplementation also required significantly fewer attempts to become pregnant, as compared with women on folic acid. But there are also other benefits to taking MMN supplements, including reduced reproductive risks ranging from infertility to miscarriage, and fetal structural defects to improved embryogenesis or placentation.
You may need only small amounts of micro-nutrients, but they are no doubt essential. Each vitamin and mineral plays a specific role in ensuring that your bodily systems function in top form, and needless to say they are vital to your overall wellbeing. In order to get more micro-nutrients from your daily diet, you should eat a wide variety of foods from the different food groups. It is also best to avoid eating fast foods and processed foods that are of low nutritional quality. Instead, opt for fresh fruits and vegetables, legumes, nuts and seeds, whole grains, lean meats, fish and low-fat dairy products.
