Five Things Your Doctor Isn’t Telling You About Your Fertility

If you search ‘how to increase my chances of getting pregnant’, Dr. Google leads you down a rabbit hole of contradicting and confusing information. This can result in additional anxiety  for couples who are already stressed about trying to make a baby. As a Naturopathic Doctor, I am constantly sifting through the latest research in order to provide my patients with the best possible care. Here are the top five facts medical doctors often don’t their patients, but I believe are key to making healthy babies.

1. What You Eat And Drink Does Impact Your Fertility

You are what you eat and so is your baby. For couples trying to conceive, there is overwhelming evidence that following a Mediterranean Diet can improve your chances of fertility.1 This diet is rich in healthy fats, vegetables, fibre, and protein from plants and fish. It minimizes processed foods, refined carbohydrates and sugars and animal protein. Couples who adhere to this pattern of eating increase their chances of getting pregnant.1 The Mediterranean Diet also boosts both the quality and quantity of sperm.1

A typical meal plan for my patients would look like the following:

Breakfast- Two organic eggs and spinach scrambled in coconut oil, top with avocado

Lunch- Chickpea and lentil salad topped with walnuts and blueberries

Snack- Celery sticks dipped in nut butter

Dinner- Wild Salmon with oven roasted sweet potatoes and vegetables

Treat- Dark chocolate (minimum 70% cocoa solids)

In addition to the food you eat, it is equally important to eliminate alcohol and caffeine from your diet. Women who consume high amounts of alcohol have a 60% increased risk of needing fertility care compared to women who identify as low consumers.2 In one study, women who drank the month prior to IVF had a 13% decrease in the number of eggs retrieved and were 2.21 times more likely to miscarry.3 Sorry men, but male drinkers are also 2.28 times more likely to not conceive during an IVF cycle.3 The evidence is very clear that alcohol is damaging to both the egg and the sperm. Since it takes approximately 100 days to build healthy eggs and sperm, alcohol should be avoided for 3 months prior to conception.4

What about caffeine? I recommend significantly reducing your caffeine intake at least one month prior to conception. Caffeine consumption greater than 300 mg/day has been associated adverse pregnancy, fertility, or neurodevelopmental outcomes, especially miscarriage.5 How much is 300mg of caffeine? One Grande Pike Place from Starbucks has 310 mg! If you cannot live without coffee, try switching to Kicking Horse Half Ass Coffee (half decaf), or green tea, which has significantly less caffeine.

2. They Didn’t Check Your Vitamin D Levels

When you announce to your doctor that you are trying to conceive or currently pregnant, there is a list of routine screening performed. This list is even more extensive at fertility clinics, however I find Vitamin D levels are often not checked. A low Vitamin D level is associated with low levels of AMH, a blood test that measures ovarian reserve.6 Although we cannot prove causation, women who present at fertility clinics are more likely to have suboptimal levels of Vitamin D than the general population.7 Especially as we enter the winter months, I recommend getting your Vitamin D levels checked.

3. Age Is The Most Important Factor

Although I strongly believe lifestyle factors and quality supplements have a huge impact on fertility, age remains the most predictive factor of overall fertility.8  Egg quality and quantity diminish with age; this means you have fewer eggs available, and those eggs are less likely to survive fertilization and implantation. The biggest decline in fertility happens in the mid-30s.8 If a women is under <35 in Ontario, she must try for a year before being referred to a fertility clinic, but only 6 months if she is >35 years old. As an entrepreneur myself, I understand the struggle between balancing career and family goals. I don’t believe we should have to choose between a promotion at work and starting a family. Corporations need to adapt their policies to allow women to have flexible working schedules and adequate maternity leave.

4. A High AMH Level Isn’t Necessarily A Good Thing

AMH, or anti-mullerian hormone is produced by immature ovarian follicles in your ovaries. It is currently the best method for measuring your egg supply, also known as ovarian reserve. AMH is not affected by the birth control pill, and can be tested at anytime during a woman’s cycle. Although a high AMH is preferred over a very low level, a very high AMH is often a sign of PCOS.9 A hallmark of PCOS is anovulation, which results in very high levels of immature follicles in the ovary. AMH is not considered a reliable test for diagnosing PCOS, but a very high level warrants further investigation.10

5. Not All Prenatal Vitamins are Created Equal

It is a common misbelief that all brands of prenatal vitamins contain the same amount of micronutrients. In reality, many commercially available prenatal vitamins contain suboptimal levels of key nutrients and many unnecessary additives, fillers and dyes. Morning sickness is common during the first trimester, and can be exacerbated by poor quality prenatal vitamins that leave women feeling even more nauseous and constipated. A 8-year study of over 18,000 women found that taking 3-5 capsules of a multivitamin per day resulted in less ovulatory infertility compared to women who took an “all in one”. 11 Essentially, one capsule is not large enough to hold all the necessary nutrients, and a good prenatal needs to be dosed at least three times a day. In my practice, I use a professional brand prenatal that contains optimal levels of micronutrients in the most absorbable form, B vitamins in the active methylated form, and no dyes or fillers. I have seen clinically that switching to this prenatal often reduces symptoms of nausea and constipation. I find the term ‘prenatal’ a misnomer because supplementation should begin 3 months prior to conception during egg development, and not stopped until three months post-breastfeeding,
