Beskrivelse

We talk with fertility naturopath and nutritionist Tasha Jennings about what embryos need to keep growing and why egg and sperm quality matter just as much in IVF as they do when trying naturally. We share practical ways to advocate for better answers after failed cycles or miscarriage and how to stop carrying the whole burden alone. • how embryo growth is fueled by egg energy through day three • why day-three timing can point to egg vs sperm factors • the 90-day preconception window for meaningful change • five pillars to support egg quality and sperm health: energy, DNA building blocks, antioxidants, cell membranes, environment • why “fine” semen results can still hide major issues, including DNA integrity • how BPA, plastics, fragrances, and device habits can affect fertility • why IVF can’t override poor egg or sperm quality, and what to ask the embryologist • common miscarriage drivers, including chromosomal issues and male contribution • when to look deeper at vaginal microbiome and immune balance • why “just relax” is unhelpful, and what support actually looks like Embryos don’t “just stop” for no reason, and hearing “everything looks fine” can be one of the most frustrating parts of trying to conceive. We sit down with fertility naturopath, nutritionist, author, and podcast host Tasha Jennings to get specific about what actually drives embryo development, why day three matters so much, and how to use that timeline to ask better questions after a failed IVF cycle. We dig into the overlooked truth that early embryo growth is fueled by what’s already inside the egg, including the mitochondria and nutrient reserves needed for rapid cell division. From there, Tasha lays out her five-part framework for improving egg quality and sperm health during the critical 90-day preconception window: boosting energy production, supplying DNA building blocks, increasing antioxidant protection, strengthening cell membranes with omega-3s and DHA, and reducing environmental stressors like BPA and fragrances. We also talk about male fertility in a way that’s practical and empowering, including why “normal” semen analysis results can still miss DNA integrity issues that affect embryo growth and miscarriage risk. If pregnancy starts but doesn’t continue, we walk through the most common reasons, including chromosomal abnormalities and what to consider when testing shows an embryo is chromosomally normal. Tasha explains when vaginal microbiome testing might matter, what to know about lactobacilli, and why immune balance and the uterine environment can be part of the story. We also name the emotional weight of this process and why “just relax” is not a plan.

Endocrine Disruptors In Daily Life And How To Reduce Exposure deep dive discussion with Helen Zee

We pull apart what recent documentaries reveal about plastics, endocrine disruptors, and the way “safe” chemical limits fail when exposure adds up across a whole day. We keep it grounded and practical, sharing realistic low-tox changes that can support fertility, IVF, menstrual health, and sperm health without spiraling into fear or guilt. • mass consumerism as the root driver of chemical overload • how regulatory silos miss cumulative exposure across food, water, textiles, and personal care • why endocrine disrupting chemicals matter beyond fertility, including metabolic health • timing of exposure vs level of exposure, especially in pregnancy windows • microplastics found in placenta, breast milk, and human blood • the body’s real detox pathways, supporting liver, kidneys, gut, lungs, and skin • practical swaps that stick, pantry changes, glass storage, safer bottles • kitchen upgrades, utensils, chopping boards, takeaway in your own container • “BPA-free” marketing and why substitutes can still disrupt hormones • PFAS and synthetic textiles, skin absorption, and simple ways to reduce contact • baby and child choices, toys, clothes, and gift registry boundaries • Dirty Dozen and Clean 15 shopping, plus baking soda produce washing • how xenoestrogens can disrupt ovulation and progesterone balance • progress over perfection as the only sustainable plan do share this Microplastics in the placenta. “BPA-free” labels that don’t mean what we think. Fertility trends shifting in ways that can’t be explained by genetics alone. That’s what sent us down the rabbit hole after watching the Plastic Detox documentary on Netflix and a new infertility documentary, and we knew we had to talk it through with clarity, not fear. We zoom out to the big picture of mass consumerism and why regulation often looks at one chemical at a time, even though real life exposure is cumulative across food packaging, canned foods, water, clothing, personal care products, and the air around us. Then we zoom in on reproductive health: sperm quality, egg health, pregnancy exposure windows, and what endocrine disrupting chemicals like phthalates, BPA, and PFAS can do to hormone signaling. We also unpack the research and headlines around microplastics detected in placenta, breast milk, and blood, and what that means for parents who are already doing their best. Most importantly, we make this actionable. We share low-tox living steps that are realistic and affordable: don’t microwave food in plastic, switch to glass for leftovers, choose stainless steel or glass drink bottles, wash produce with baking soda, use the Dirty Dozen and Clean 15, invest in a quality water filter, and focus on supporting the body’s real detox pathways by peeing, pooping, and sweating. We also do a rapid-fire myth check so you can separate good science from clever marketing.

Genetic Counseling For Fertility a Deep Discussion with Mona Saleh

We sit down with genetic counsellor Mona Saleh to unpack what genetic counseling really is and why it can be a game changer when you are trying to conceive or navigating IVF. We talk through carrier screening, Fragile X confusion in real-world reports, and how preimplantation genetic testing can support clearer choices and better odds. • what a genetic counselor is and why the role combines education with psychosocial support • why family history still matters even with modern genetic testing • how genetic carrier screening works and what it can reveal without any known family history • the common conditions discussed in screening like cystic fibrosis, Fragile X syndrome, and spinal muscular atrophy • a real example of a Fragile X report being misread and how the anxiety gets resolved • what preimplantation genetic testing is in IVF and how euploid vs aneuploid embryos affect outcomes • why asking questions early can protect your peace and improve decision-making • how to find Mona and when to check for in-house clinic genetic counselors A genetic test result can look like a wall of numbers, and when you are already carrying the emotional weight of IVF or fertility treatment, that uncertainty can hit hard. We’re joined by genetic counsellor Mona Saleh, who has three decades of experience helping people make sense of reproductive genetics with clarity, care, and zero shame for not knowing the jargon. We talk about what genetic counselors actually do, how they translate medical reports, and why that “translator” role can be the difference between panic and a plan.  We start with the basics that matter most for real life decisions: family history, inherited conditions, and how genetic counseling supports you as a person, not just a lab result. From there we dig into preconception genetic carrier screening, including common conditions like cystic fibrosis, Fragile X syndrome, and spinal muscular atrophy (SMA). Mona explains why carriers are often healthy, how two carriers can face a one in four risk for an affected child, and how informed choice looks different for different families, partners, and donor situations.  One of the most powerful moments comes from a true story: a Fragile X carrier screening report that was misread because the format was complex, which raised anxiety for both the GP and the patient. Mona walks us through how those reports are structured, how misunderstandings happen, and how a calm, expert conversation can quickly restore perspective and guide next steps.  We also explore preimplantation genetic testing (PGT) in IVF, including chromosome screening for euploid vs aneuploid embryos, why imbalance becomes more common with age, and how PGT can improve the chance of pregnancy while reducing miscarriage risk. If you’ve been wondering whether testing embryos increases IVF success, what it can and cannot tell you, or how to advocate for yourself with your clinic, you’ll leave with clearer language and better questions.  Subscribe, share this with someone who needs steadier footing, and leave a review to help more people find support on their fertility journey.

Your Body Chooses Safety Before Pregnancy And Here Is How To Help It a Great Discussion with Tammy Shemesh

We talk with fertility nutritionist Tammy Shemesh about why disordered eating and food anxiety are far more common in fertility treatment than most people realize, and how that hidden stress can disrupt hormones and cycle health. We share a more compassionate path that blends evidence-based fertility nutrition with nervous system safety, cycle awareness, and real pleasure in eating. • the research on disordered eating in fertility treatment and why it often goes unspoken • what disordered eating can look like beyond clinical diagnoses, including restriction, orthorexia, binge cycles and rigid rules • how chronic stress shifts the body into survival mode and disrupts ovulation, progesterone and thyroid function • the link between gut health, inflammation, estrogen clearance and common fertility conditions like PCOS, endometriosis and fibroids • feminine energy as receptivity, rest and embodiment, and how diet culture pushes control and distrust • the four menstrual cycle phases and how energy, mood and nutrition needs can change across the month • three practical steps to rebuild trust with food and your body, starting today • resources mentioned, including Brene Brown’s Atlas Of The Heart Food can look “perfect” on paper and still feel like a war in your head. If you have ever followed fertility diets, tracked every bite, or swung between restriction and emotional eating while trying to conceive, you are not alone and you are not broken. Liz sits down with clinical nutritionist and certified fertility nutritionist Tammy Shemesh to talk about the quiet reality that many people bring disordered eating patterns into fertility treatment and often never mention it to their doctor, even though it can meaningfully impact hormones, cycle regularity, and stress levels. We unpack what disordered eating can look like beyond a formal diagnosis: chronic dieting, orthorexia and clean eating fixation, rigid food rules, binge cycles, and using food for control when fertility feels out of control. Tammy explains how chronic stress and food anxiety keep the nervous system in fight or flight, pulling resources away from reproduction. We connect the dots between cortisol, progesterone, ovulation signaling, thyroid function, estrogen clearance, inflammation, and gut microbiome health, and why “more willpower” is not the solution. You will also hear a powerful reframe around feminine energy as receptivity, intuition, rest, and cyclical living, plus a simple guide to the four phases of the menstrual cycle and what each phase tends to need. Tammy shares three practical steps you can start now: add one act of genuine nourishment and pleasure daily, track your cycle as body reconnection, and honor what your current phase asks for, especially rest. If you want a calmer, more sustainable approach to fertility nutrition that supports both body and mind, this conversation is for you.

How To Navigate International Surrogacy And Donor Options Conversation with Anita from Growing Families

We sit down with Anita from Growing Families to talk honestly about international surrogacy and donor pathways, from embryo shipping delays to the paperwork, timing, and trust issues that can shape every decision. We share what helps intended parents stay grounded through the long stretches of waiting and the very real emotional swings that show up from matching to birth and beyond. • how Anita supports intended parents globally through surrogacy and donor journeys • who uses surrogacy and donor eggs, donor embryos, and double donor pathways • real-world challenges with embryo shipping, hand-carry logistics, and changing travel routes • paperwork, reports, notarization, and why exit planning matters early • why mindset becomes the hardest part and where overwhelm tends to spike • what makes independent concierge-style support different from going it alone • Anita’s personal story of cancer, embryo loss, and rebuilding trust with better due diligence • practical first steps like consultations, webinars, and understanding country rules • common early mistakes like ignoring timelines, donor dropouts, and surrogate screening setbacks The hard part of surrogacy is not just getting a “yes” from a clinic. It’s the waiting, the paperwork, the cross-border rules, and the moments where you realize you cannot control the timeline the way you want to. We’re joined by Anita from Growing Families, a global support manager with both professional expertise and lived experience, to talk through what intended parents really face on international surrogacy and donor conception paths. We get practical about the logistics that can stall a dream, including embryo shipping and biomaterial transport, flight-route disruptions, hand-carry delays, and the mountain of documentation different countries require. Anita explains who she supports, from heterosexual couples who cannot carry, to gay couples and single men who need an egg donor and surrogate, to single women considering donor eggs, donor sperm, or double donor options. We also discuss why “know the exit plan” matters early, especially when return-home and citizenship steps can be time-sensitive. Just as important, we talk about the emotional reality. Mindset gets tested at every stage: IVF updates, surrogate matching, gaps in communication, and the countdown to birth when excitement and fear can hit at the same time. Anita shares how her own cancer diagnosis and surrogacy journey shaped her approach, and what she wishes more people understood before they sign with an agency or choose a destination like Georgia, Colombia, or the USA. If you’re researching surrogacy abroad, listen for the questions you should ask, the mistakes to avoid, and the support that can make the process feel steadier and safer.  Subscribe, share this with someone who needs it, and leave a review so we can reach more families building their future.
