Have you ever seen a headline claiming a certain food can boost your fertility and rolled your eyes? You're not wrong to be sceptical, and most of what circulates online about diet and conception is wellness noise dressed up as science.

This time, the science actually holds up. A new 2026 study traces a real, step by step mechanism from what's on your plate to whether an embryo implants.

In this episode of The Science of Motherhood, Dr Renee White breaks down a new mouse study linking dietary fibre, gut bacteria and the uterine immune system. She walks through how the pathway works, where the research falls short, and what's reasonable to take from it if you're trying to conceive.

You'll Hear About:

• Why mouse studies are used in fertility research
• What the new 2026 fibre study found
• How gut bacteria influence uterine immune tolerance
• Why this mechanism doesn't yet prove human benefit
• What foods support this specific fibre pathway

You don't need to overhaul your diet to take this seriously. Paying attention to fibre quality, not only quantity, is a small, evidence-backed step available to you now. The mechanism is real, even if the guarantee isn't, and that still counts for something.

You've sat through an antenatal appointment focused on blood pressure and bump measurements, wishing there'd been room to talk about how you were actually feeling. Midwives want that room too, working inside appointments measured in minutes. There's real momentum building to bring emotional wellbeing further into that time together.

Two researchers went looking at exactly what that momentum looks like in practice, and how to act on it without asking midwives to find time they don't have.

In this episode of The Science of Motherhood, Dr Renee White sits down with Lesley Pascuzzi, childbirth educator and perinatal mental health researcher, and her colleague Nicole Freeman, midwife and PhD researcher in early pregnancy care, to unpack what midwives told them about supporting mental health during pregnancy. Together they explore where the system falls short, and the pilot program already testing a different way forward.

You'll Hear About:

• Why the current model centres illness over wellness
• What midwives believe a well woman looks like
• How time pressure shapes mental health conversations
• Why continuity of care changes everything
• What the new pilot program is testing

Knowledge is the foundation of advocating for your own mental health, in pregnancy and beyond. The more you understand about your options, the more equipped you are to ask for exactly what you need.

If you've ever left an appointment feeling rushed or unheard, send this to a friend who's navigating pregnancy right now. And subscribe so you don't miss an episode of The Science of Motherhood.

Your parents or your in-laws are going to tell you they did things differently and you turned out fine, right in the middle of a conversation about sleep safety or feeding choices, and you can feel the eye roll building before they've even finished the sentence. Their love is real, and you don't have to brace for it each time they visit.

In this episode of The Science of Motherhood, Dr Renee White unpacks what grandparents and in-laws genuinely need to know before the baby arrives, cutting through outdated advice to share what the current evidence actually supports, what's changed, and what's genuinely worth doing differently.

You might be pregnant or newly postpartum and quietly dreading the moment a well-meaning relative tells you how it used to be done. If you're the grandparent listening in, most of those moments come down to a gap in information that's easy to close. Start the conversation early, and you give your village the chance to actually hold you up, the way you deserve.

You'll Hear About:

• Why vaccinations protect newborns before six weeks
• How updated safety guidance differs from old advice
• What matrescence means for the woman you love
• Why cuddles are something to be earned
• How to offer help without the unsolicited opinions

You don't have to manage anyone else's feelings while you're still learning your own baby. The right people in your life will meet you with curiosity instead of correction, and that's the kind of village worth building around yourself and your baby.

Share this with the grandparent, aunty, or friend who wants to support you well, and with the parent who needs the words to start this conversation early. And subscribe so you don't miss an episode of The Science of Motherhood.

The mental and emotional weight of trying to conceive doesn't disappear once you're pregnant, or once the baby arrives. For many women, it quietly shapes everything that comes after.

Sometimes the hardest part isn't the fertility treatment itself. It's carrying the aftermath of it into motherhood without anyone acknowledging that you went through something significant to get there.

In this episode of The Science of Motherhood, Dr Renee White sits down with Dr Edna Lekgabe, certified perinatal and reproductive psychiatrist practising in Melbourne, to explore the mental health dimensions of the trying to conceive journey. They cover the difference between normal anxiety and clinical anxiety, how IVF trauma shows up in the body long after treatment ends, and why perinatal mental health challenges are never a personal failing.

This is the final episode of the six-part Trying to Conceive series on The Science of Motherhood.

In this episode, you'll hear about:

• Why what you're feeling is a nervous system response, not a character flaw
• How to recognise when anxiety has moved from visitor to renovation
• What IVF trauma looks like in the body and why it often goes unidentified
• How medication decisions are made with a risk-versus-risk framework
• Why reaching out early makes a difference

Your mental health through this journey is part of the journey. It deserves the same attention as everything else. There is support available, and you deserve to use it.

The emotional side of a fertility journey is real, and it's the part that often goes unspoken. You can walk into treatment prepared with every medical question imaginable and still feel blindsided by the weight of the waiting, the uncertainty, and the grief that can come when things don't go to plan.

That gap deserves more airtime than it gets.

In this episode of The Science of Motherhood, Dr Renee White sits down with Dr Giselle Crawford, fertility specialist and gynaecologist with more than ten years of experience in obstetrics, gynaecology, and infertility care, to explore the emotional terrain of fertility treatment and what genuinely good care looks like from the inside. They cover everything from managing expectations through the IVF process, to navigating grief, supporting your relationship, and knowing when to pause.

This episode is Part 5 of the Trying to Conceive series on The Science of Motherhood.

You'll Hear About:

• Why emotional preparation matters as much as medical readiness
• How to understand the concept of attrition in IVF
• What stress actually does (and doesn't) do to fertility outcomes
• How partners can move from spectator to co-pilot
• Why stopping treatment isn't giving up

Having language for what you're going through makes it easier to carry. This episode gives you that, alongside the science to back it up.

If you've been trying to conceive for a while, you've probably found yourself down a research rabbit hole at some point, reading forum threads at midnight and trying to decode acronyms you barely know. IVF, IUI, FSH, ICSI. The information is out there, but it doesn't always feel like it was written for you.

Understanding the difference between your options, and knowing the right questions to ask, can make a conversation with a fertility specialist feel far less overwhelming.

In this episode of The Science of Motherhood, Dr Renee White sits down with Dr Denise Nesbitt, obstetrician, gynaecologist, and fertility specialist at Hunter IVF, to unpack the key differences between IUI and IVF, including when each is recommended and what to actually expect from both processes. They explore sperm health, egg freezing, success rates, and what's really happening during the two-week wait.

This episode is Part 4 of the Trying to Conceive series on The Science of Motherhood.

You'll Hear About:

• How doctors decide between IUI and IVF
• What actually happens during each fertility cycle
• Why sperm health matters more than most people realise
• What success rates mean and what influences them
• How to emotionally prepare for the two-week wait

Starting this journey is brave. Having the right information means you can walk into that appointment knowing the right questions to ask, and feeling far less alone in the process.

You've probably been told to "just relax" at some point on your fertility journey. Maybe by a friend, a family member, or even a health professional. And if you're anything like most people trying to conceive, you probably wanted to throw something at them.

That advice isn't just unhelpful. It's both slightly right and completely missing the point.

In this episode, Dr Renee White unpacks the real science behind stress, mindfulness, and fertility, cutting through the noise to tell you what the evidence actually supports, what it doesn't, and what's genuinely worth trying.

This is part three of our six-part Trying to Conceive series.

You'll Hear About:

• Why stress and reproduction are biologically competing systems
• How chronic stress disrupts your cycle and hormones
• What mindfulness reliably improves (and what it doesn't)
• Why pregnancy rate claims need more evidence behind them
• Five evidence-backed practices worth integrating now

The fertility journey asks so much of you. It can feel like your body is working against you, when the science tells a more nuanced story. Your nervous system and your reproductive system are in conversation, and understanding that relationship puts something real back in your hands.

Most of us weren't taught that what happens before conception matters. You were told to take a folate supplement, book in when you got a positive test, and go from there. But there's a window of time before you even start trying that can shape not just your pregnancy, but your child's long-term health.

The science on preconception care has moved significantly, and most people still aren't hearing about it.

This is Part 2 of our six-part Trying to Conceive series.

In this episode of The Science of Motherhood, Dr Renee White sits down with Dr Eliza Hannam, GP, International Board Certified Lactation Consultant, and founder of Nurtured Medical, a specialised perinatal clinic in Sydney, to explore what genuinely evidence-informed preconception care looks like. Together they unpack what the periconception window actually means, what testing is available and when to seek it, and what both partners can do to optimise health before pregnancy begins.

You'll Hear About:

• Why preconception health affects your child's long-term metabolic health
• What a thorough preconception GP appointment covers
• Which supplements and nutrients matter most before conception
• How to read your cycle beyond what any app can tell you
• When to seek fertility support without waiting 12 months

The periconception window is a gift of time, and knowing how to use it well changes things. You don't need to be a biochemist to understand it. You just need the right conversation.
