Fertility, Reinvented: How WeNatal redefined fertility as a “we” journey

When you meet someone and just click, it’s like a puzzle piece snapping perfectly into place.

That’s exactly what happened to us more than a decade ago at a corporate job. We bonded over all the things you do in your twenties: falling in love, chasing promotions, and dreaming about starting families.

Then, life threw us something we weren’t prepared for: miscarriage.

For Vida, it happened twice. For Ronit, it happened after easily conceiving her first daughter. The pain was deep, but the confusion was worse. Why was this happening and why were the answers so vague?

Our doctors said the things women hear all too often: It’s random. It’s your age. It’s out of your control.

But deep down, we didn’t believe that was the whole story. So we did what many women do when we’re desperate for answers: we started researching like our lives depended on it.

What the research revealed about fertility, nutrition, and miscarriage risk

Night after night, we fell down research rabbit holes. We read medical journals, fertility studies, nutrition reviews, anything that might explain what was happening inside our bodies. And what we discovered shocked us. 

There was a growing body of scientific evidence showing that nutrition and lifestyle before conception can significantly  influence fertility, miscarriage risk, and even a baby’s lifelong health.

And the biggest surprise ? It wasn’t just about the woman.

Study after study showed that sperm health, including motility, count, and DNA quality, plays a critical role in conception and miscarriage risk. Poor sperm quality has been linked not just to lower fertility rates, but also to higher rates of pregnancy loss and even developmental challenges later in life.

Even more fascinating: sperm completely regenerates every 70–90 days. That means what a man eats, drinks, and does over the course of just three months can reshape the health of his sperm and potentially the health of his future child.

So we started asking a question that seemed almost obvious: Why are men rarely part of the fertility conversation? Why is all the pressure placed on women to fix what’s really a two-person biological process?

The preconception window: Why the 3–6 months before pregnancy matter

We decided to test what we’d learned,  not just on ourselves, but with our husbands.

We both committed to making changes alongside our husbands. Our partners cleaned up their diets, swapped processed foods for whole ones, reduced alcohol, and began targeted supplements with nutrients like CoQ10, selenium, methylated B vitamins, and omega-3s,  which research has shown can improve sperm motility and reduce oxidative stress.

At the same time, we focused on our own preconception health: stabilizing blood sugar, supporting hormone health, improving sleep, and prioritizing key nutrients like methylated folate, choline, iron, and zinc that play essential roles in egg quality and early fetal development.

A few months later, something incredible happened. 

We each found out we were pregnant again, with due dates just weeks apart.

That’s when it all clicked. What researchers call the “preconception window”, or  the three to six months before conception,  isn’t just preparation time. It’s a period that can influence fertility, pregnancy outcomes, and even your child’s long-term well-being. Eggs mature and sperm regenerate during this window, meaning your lifestyle and nutrient status are literally shaping the next generation.

The science supporting fertility for both men and women

As we dug deeper and continued researching, our personal experience was reinforced by emerging fertility science. Studies show that:

• Couples who follow whole-food, Mediterranean-style diets tend to have higher conception and live-birth rates.
  
  
• Men’s metabolic health, including weight, blood sugar, and inflammation, can directly influence sperm quality and miscarriage risk.
  
  
• Paternal nutrition and oxidative stress may influence the sperm epigenome, affecting embryo development and even the baby’s long-term health.
  
  
• Up to 60% of the population may struggle to properly convert synthetic folic acid (used in many prenatal vitamins) into its active form while methylated folate is a nutrient essential for early neural development.

We quickly realized the fertility system had a blind spot. Women were told to “just take a prenatal” and men were told… nothing.

Why we created WeNatal: Preconception support for both partners

We started WeNatal with a simple question: What if getting ready for pregnancy wasn’t just about her body, but about their health together?

Initially, we set out to make a preconception supplement for men, because no one was addressing sperm health. But the deeper we looked, the more we realized the prenatal market for women was missing the mark and had gaps too. Many prenatal vitamins relied on synthetic folic acid. Others contained the right nutrients but in doses too low to be meaningful, or required swallowing multiple large pills during a time when nausea can already be overwhelming.

So we created WeNatal, a comprehensive preconception and prenatal line designed for both partners. 

Our formulas prioritize:

• Bioavailable nutrient forms
• Evidence-informed nutrient levels
• Clean, thoughtfully sourced ingredients
  
  

But more importantly, WeNatal was built on the belief that preparing for pregnancy should start with “we,” not “me.”

Our mission expanded beyond supplements. We wanted to help educate couples to truly understand the power of the preconception window and how that 100-day period can meaningfully influence fertility, lower miscarriage risk, and nurture the health of your future baby.

Fertility and preconception health: Common questions

Why is sperm health important for fertility?

Sperm health plays a critical role in conception, pregnancy success, and even the long-term health of a child. Healthy sperm need strong motility, normal morphology, and intact DNA to fertilize an egg and support early embryo development. Research has shown that poor sperm quality may contribute not only to infertility, but also to an increased risk of miscarriage and pregnancy complications. Because sperm regenerates roughly every 70–90 days, nutrition, lifestyle, and targeted nutrients during the months before conception can significantly influence sperm health.

What nutrients support sperm health and fertility?

Several nutrients have been studied for their role in supporting sperm quality and male fertility. Antioxidants such as CoQ10, selenium, zinc, and vitamin C help protect sperm from oxidative stress, which can damage sperm DNA. Omega-3 fatty acids support sperm membrane health and motility, while B vitamins like methylated folate and B12 support healthy cell division and DNA synthesis. A balanced diet rich in whole foods alongside targeted preconception supplements may help support optimal sperm health.

What is the preconception window?

The preconception window refers to the three to six months before pregnancy, when both egg and sperm development are actively occurring. During this time, lifestyle choices such as nutrition, sleep, exercise, stress management, and environmental exposures can influence fertility and pregnancy outcomes. Because sperm regenerate every few months and eggs undergo critical maturation before ovulation, the habits couples adopt during this window may help support healthy conception and fetal development.

When should couples start preparing for pregnancy?

Many fertility experts recommend that couples begin preparing for pregnancy at least three to six months before trying to conceive. This allows time to optimize nutrient status, improve diet and lifestyle habits, support hormone levels, and address factors that may impact egg or sperm health. Starting early can help create a stronger biological foundation for conception and a healthy pregnancy.

A note from WeNatal on going from “me” to “we” and the future of fertility

Today, new research continues to confirm what we learned the hard way: fertility is a whole-body, two-person equation.

The choices both partners make from what you eat, how you move, how you sleep, how you manage stress, and the nutrients you take, can influence fertility, pregnancy outcomes, and the long-term health of your future child.

WeNatal was born out of heartbreak, hope, and science. Our mission is to help couples shift the fertility conversation from me to we by empowering both partners with the tools, knowledge, and nutrients to support healthy conception together.

If you’re preparing for pregnancy, we encourage you to start with education and intention. Our preconception guide walks couples through the key steps to support fertility, optimize sperm and egg health, and prepare your bodies for pregnancy.

And if you’re looking for targeted nutritional support during this time, our WeNatal supplements for women and men were designed to support the preconception window with nutrients chosen to optimize fertility, pregnancy, and beyond.

Because when it comes to creating the healthiest little humans imaginable, the journey truly begins together. And we really are stronger as “we” than “me.”
