You don’t need another supplement stack or another diet trend to “fix” your fertility.

What actually moves the needle?
👉 Evidence-based labs
👉 A clear plan for your hormones, nutrition, and cycle health
👉 Guidance that cuts out the guesswork

Because the truth is… fertility isn’t about doing more, it’s about doing the right things in the right order.

That’s exactly what I help my patients with — so you can stop spinning your wheels and finally feel confident you’re giving your body the best chance possible.

3 Research-Backed Things to Do Before IVF (That Most People Overlook) 🧬

If you’re preparing for IVF, you need more than just meds and appointments — your labs, thyroid, and diet can all impact your success.

Here’s what the research says:

1️⃣ Low iron saturation and ferritin

Trying to get pregnant with Hashimoto’s? Don’t wait until your labs are “off” to take action.
Before I got pregnant, I made it a priority to optimize my thyroid—even though I was technically euthyroid (normal thyroid labs).
Here’s why:
🧬 Thyroid antibodies can be found in the fluid around your eggs
📉 Hashimoto’s is linked to lower AMH + reduced ovarian reserve
🚫 You can have normal TSH and still struggle with fertility or early miscarriage

Women with Hashimoto’s deserve closer monitoring and a personalized plan—because pregnancy puts major stress on your thyroid, and you need to be ahead of it.

✨ If you’ve been wondering what else you can do to support your fertility with Hashimoto’s, I’d love to help.

Looking for ways to improve male fertility?You HAVE to hear about this mind-blowing study! In 2017, a randomized controlled trial was conducted to review the impact of exercise, specifically the use of aerobic and resistance exercise, had on s***m health + pregnancy rates in males previously diagnosed with abnormal s***m parameters who had been unsuccessful for at-least 12 months.

The participants were splits up into two groups
The “non-exercise” group
The exercise group.
The exercise group exercised three times a week using a combination of aerobic and resistance styles training workouts for 24 weeks.

During this study, researchers measured semen parameters, pregnancy rates as well as inflammation markers and oxidative stress.

By the 24 week mark, the exercise group experienced:
Improved progressive motility by 49.8%
Improved Morphology by 74.3%
Improved S***m Concentration by 66.5%
Improved S***m Count by 84.7%
Reduction in DNA fragmentation by 43.1%
Now although this alone was impressive, what was most impressive about the study was that of the 258 men who were part of the exercise group, 191 got their partner pregnant within the 24 week study. Of those pregnancies, there were 180 live births!

In the “non-exercise” group, there were 263 men, there were 7 pregnancies and 3 live births.

If that isn’t enough data to convince you to make exercise a priority, I don’t know what is.

It’s studies like these that make me so passionate about the work that I do as a naturopathic doctor specializing in fertility and the exact reason I created our top rated course fertility foundations to help YOU get pregnant too!

Deciding to undergo IVF isn’t a decision that you took lightly. Not only is there an financial cost but there was a lot of blood, sweat and tears involved in getting you to this point with the ultimate goal of having that baby you so desperately deserve.

So here are a few important tips to remember when preparing for IVF:
It takes about three months for an egg to fully mature. This means that what you do the three months prior to IVF REALLY DO MATTER and for many patients we may suggest they postpone their IVF start date in order to make sure we have their body completely ready for IVF.
Use food as medicine. What you eat, the information you provide your body each and every day impacts not only your hormones but your cells on a cellular levels, so be kind to your body and improve your egg and embryo quality by making your diet a priority. (Remember that in order to make hormones you needs healthy fats and protein, so sticking to an all plant-based vegan diet, may not be the best option)
Movement is power. Studies have shown that a combination of aerobic and resistance training can not only improve your partner’s semen analysis but improve the chances of pregnancy and live birth rates! So make movement, at least three times a week, a priority for both you and your partner
Support your nutrient status. When it the last time you had your iron, ferritin and vitamin D levels checked? Suboptimal to low nutrient status has been associated with less successful IVF cycles and increased risk of miscarriage rates and fetal growth delays. Making sure to get a comprehensive nutrient blood test is an important first step to know exactly what your body needs and doesn’t.
Make sleep a priority. According to the American Society for Reproductive Medicine's study, women with low quality sleep had lower rates of fertility than those getting adequate rest

YOU ARE NOT ALONE. Over 21 million Americans are reported to be suffering from some form of depression. Unfortunately, like many couples who are suffering from infertility, they are less likely to seek out help for their depression. So, although you may be thinking about your exercise routine, the supplements you are taking and the food you are eating to optimize your fertility, one of the most important aspects to address during your fertility journey is your mental health. Seeking adequate support and guidance from a medical professional is extremely important. Although there is an assumption that medication is the only option when treating depression, the reality is some of the most successful providers helping patients overcome depression have found that lifestyle, counseling and dietary modifications should all be considered alongside pharmaceutical interventions.

Trust me, I have totally been there. Ovulation Predictor Kits can be an extremely useful tool when it comes to understanding and tracking when, and if, you ovulate. However, if you have been trying for a while, chances are you are totally OVER using this “helpful tool” and now may even notice they trigger overwhelm, anxiety and stress during your fertility journey.

So should you use ovulation predictor kits or not? Generally, speaking I love using ovulation predictor kits to help patients who recently started trying to better understand how to track their cycles and fertile window. Since you don’t always ovulate in the exact same way each month, I generally like my patients to use OPKs for 3-4 cycles to help us better understand their unique cycle and hormonal patterns. That being said, unless we have made recent changes to their diet, supplement or medication routine, I usually have patients stop using OPKs.

I know. WHAT? Yes! OPKs are helpful but they predict but DON’T CONFIRM ovulation so although they are helpful in our initial investigation of your fertility workup, it’s not the only tool we should be using.

This is where comprehensive testing, understanding optimal vs. normal results and evaluating other connected factors like thyroid, adrenal and gut health have helped so many of our patients get pregnant and avoid IVF.

If you are tired of feeling overwhelmed and stressed, I highly recommend enrolling into Fertility Foundations to get the real support you need! (LINK IN BIO)
