Preparing for pregnancy involves so much more than starting a prenatal vitamin.
Recently I co-hosted an expert session with Dr. Leah Gordon, a naturopathic doctor and fertility consultant who specializes in integrative fertility care and root-cause hormone balancing.
We talked about what we call the golden window, also known as the preconception window, and why it's such a valuable time to support your health before pregnancy. Here's what we covered.
Preconception health goes beyond conception
Preparation can start well before a positive pregnancy test, for both partners. Dr. Leah shared three reasons it matters:
You can address issues now. Options are more limited once you're pregnant. Gut health, hormones and nutrient deficiencies are easier to address beforehand.
Your own health trajectory. Your health often isn't the priority with a new baby. The foundations you build now carry you through pregnancy and postpartum.
Your baby's health. Through epigenetics, your choices influence how genes are expressed, for you and for your future child.
When to start. Eggs and sperm take about three months to mature. Dr. Leah's timeline: 6 to 12 months before trying is optimal, giving you time to build foundations and address root causes. 3 to 4 months is the minimum, covering one full maturation cycle. Less than 3 months still supports her eggs up to ovulation, but has less impact for him. That's also when to start a prenatal for her, or a high-quality multi for him.
Dr. Leah shared five practical foundations for supporting fertility:
Nutrition: whole-food forward, with high-quality protein and fat at every meal, nutrient-dense seafood for zinc and omega-3s, brightly colored foods for their antioxidants, probiotic-rich foods, and plenty of variety. She also suggested favoring cooked over raw to support digestion.
Lifestyle: protect your sleep with a steady sleep-wake cycle and screens out of the bedroom, phone included. Snoring, grinding, clenching or mouth breathing can point to disordered sleep breathing and are worth investigating.
Supplements: targeted, not generic. Support for egg and sperm health, omega-3s and probiotics, plus personalized support where it fits, such as hormone-balancing support for her with PCOS.
Stress: there's a lot of doing in preparing for pregnancy, and when it doesn't happen quickly, many of us lean even harder into control. Dr. Leah talked about balancing that doing and planning with trust, intuition and surrender.
Spirit: connection to your partner, your baby and yourself.
Preparing for pregnancy is a team effort
Prepping for pregnancy is not just a woman's thing. Dr. Leah shared that about half of fertility challenges involve a male factor. Sperm health plays a role in conception, fertility and miscarriage, and paternal epigenetics influence the health of the baby. Yet male testing isn't as common in conventional care as it should be, so test him early.
Know your numbers. Bloodwork and sperm testing during the preconception window show where to focus, for both of you. Dr. Leah's free Fertility Lab Guide for Him & Her covers what to test and the optimal ranges.
Do you need genetic testing before pregnancy?
Different tests answer different questions. I like to think of your DNA as an instruction manual: your genes are the chapters, and variants are typos in the text. We all have variation, and it's part of human diversity, but some variants can impact fertility.
There are two general kinds of genetic testing:
Medical and diagnostic testing looks for genetic conditions with a high impact, like recessive conditions such as cystic fibrosis. Carrier screening and karyotyping fall here.
Functional testing looks at how your body works. These are predispositions, not a diagnosis, and nutrition, lifestyle and environment shape how they're expressed. Nutrigenomics and functional genomics fall here.
You may already be familiar with one genetic test. Many people learn their baby's sex during pregnancy through a blood test called NIPT or NIPS. What many don't realize is that it's a type of genetic screening: it looks at DNA from the placenta circulating in the mother's blood, including information about the baby's sex chromosomes.
Carrier screening. We have two copies of each gene, and carrier screening checks whether you carry a typo in one copy. If both partners carry a typo in the same gene, they usually aren't affected themselves. But with each pregnancy, there's a 1 in 4 chance that both pass down the changed copy, which can lead to a recessive genetic condition in their child.
In my experience, carrier screening often isn't offered until someone is already pregnant. Knowing earlier can give you more options and more time to plan, no matter what you decide. For some couples, it opens a conversation about options like IVF with genetic testing of embryos. It can also matter for pregnancy and after birth, especially if a baby might need specialized care or treatment.
Testing based on your personal and family history. For example, a karyotype is often considered for couples who have had multiple miscarriages. Instead of looking for small typos within a single gene, it looks at each partner's chromosomes for large changes, or "big typos," that can increase the risk of miscarriage. A family history of a genetic condition can also point to specific testing.
Nutrigenomics and functional genomics. For both partners, understanding your pathways can help personalize support for fertility, pregnancy and postpartum.
Not all genetic tests are created equal
There are so many genetic tests out there, so it's important to choose the right one for you. Look for a reputable lab with appropriate clinical validation.
If a company promises to tell you everything you need by testing five genes and then selling you a bunch of supplements, that's probably not the most helpful approach.
Most importantly, you deserve proper interpretation of your results, with personalized recommendations from genetics experts who understand both the science and the limitations of testing. The goal isn't just a genetic report. It's understanding what that information means for YOU, and what, if anything, you should do differently.
Bringing all the pieces together
Genetics is one important piece of the puzzle. When we bring together your personal and family history, blood work, sperm testing, and your genetics, we can create a much more personalized plan.
The goal is never to overwhelm you. At Golden Genetics we're really against siloed care. We want all of these pieces to work together, with guidance along the way, to support you and your partner.
This is your golden window: a powerful time to shape how your pregnancy and birth go, and the health of everyone involved, including your future children.
