The Men's Fertility Nutrition Podcast

CoQ10 is one of the most studied supplements in male fertility. The signal is stronger than many others, but it is not straightforward.In this episode, Alex breaks down what CoQ10 actually does, why it is often recommended for sperm health, and what the research really shows.You’ll learn how CoQ10 supports mitochondrial energy production, why that matters for sperm motility, and where the evidence appears strongest. The episode also explores the limits of the research, including why improvements in semen parameters do not always translate into pregnancy or live birth outcomes.This is a practical, balanced look at where CoQ10 may fit into a broader fertility plan.What You’ll LearnWhat CoQ10 is and how it works in the bodyWhy sperm require high energy production to functionWhy CoQ10 is often linked with sperm motilityWhat studies suggest about count, motility, and morphologyWhy stronger semen parameters do not always equal better fertility outcomesHow to think about CoQ10 in context rather than as a shortcutKey TakeawaysCoQ10 plays a central role in cellular energy productionThe strongest research signal appears to be sperm motilitySome studies suggest benefits for other parameters, but findings are less consistentEvidence for pregnancy or live birth outcomes remains limitedCoQ10 may be useful in selected contexts, but it does not replace foundations like diet, sleep, alcohol reduction, and metabolic healthWho This Episode Is ForMen with reduced motility on semen analysisCouples preparing for conception or IVFMen considering supplements and wanting an evidence-based viewAnyone trying to understand where CoQ10 fits in practiceWhat’s NextNext episode: Not All Evidence Is Equal — how to think about fertility nutrition research, conflicting studies, and what to trust.DisclaimerThis podcast is for general education only and does not replace personalised medical or nutrition advice.

Episode SummaryIn this episode, Men’s Fertility Dietitian Alex Hardy breaks down antioxidants and their role in male fertility. While the biological rationale is strong, the clinical outcomes are far less consistent. We explore how oxidative stress affects sperm, why antioxidants are often recommended, and what the research actually shows when it comes to semen parameters, DNA fragmentation, and fertility outcomes. This episode builds on the previous discussion of DNA fragmentation and sets up a more targeted look at individual nutrients in upcoming episodes.What You’ll LearnWhat oxidative stress is and why sperm are vulnerable to itHow antioxidants are thought to support sperm healthWhat clinical trials and meta-analyses showWhy results across studies are inconsistentThe difference between improving semen parameters and improving fertility outcomesWhere antioxidants may fit in practiceKey TakeawaysAntioxidants make biological sense, but outcomes are inconsistentSome studies show improvements in sperm parameters, others show little or no effectEvidence for improved pregnancy or live birth outcomes is limited and low certaintyImprovements in lab markers do not consistently translate into real-world fertility outcomesBlanket supplementation is unlikely to produce reliable resultsAntioxidants are best used as targeted tools, not default solutionsEpisode OutlineOxidative stress and sperm vulnerabilityBiological rationale for antioxidantsWhat clinical research shows Cochrane reviews and mixed evidenceThe MOXI trial and what it tells usWhy results vary across studiesDiet patterns versus isolated nutrientsWhere antioxidants fit clinicallyPractical ConsiderationsFocus on the foundations first — diet, lifestyle, and metabolic healthAvoid assuming more antioxidants equals better outcomesBe cautious with supplement stacking and high-dose combinationsConsider whether there is a clear indication, such as oxidative stress riskUse supplements deliberately, not as a starting pointWhat’s NextIn the next episode, we take a more targeted approach by looking at one of the most studied nutrients in male fertility, CoQ10, and where it fits in practice.DisclaimerThis podcast is for general education only and does not replace personalised medical or nutrition advice.

Episode SummaryA semen analysis can look acceptable on paper — but that doesn’t always mean sperm DNA is in good shape.In this episode, Men’s Fertility Dietitian Alex Hardy explains sperm DNA fragmentation — a deeper layer of sperm quality that isn’t captured by standard semen analysis.We explore what DNA fragmentation actually is, why it matters for fertility and pregnancy outcomes, and why it isn’t part of routine testing for most men.The episode also breaks down what drives DNA damage in sperm, when testing may be useful, and how lifestyle, health, and targeted interventions can influence sperm quality over time.Main TopicsWhat sperm DNA fragmentation is and how it differs from standard semen analysisWhy normal semen results don’t always reflect full sperm qualityHow DNA fragmentation relates to fertility, IVF outcomes, and miscarriage riskWhy DNA fragmentation testing isn’t routinely recommendedWhen testing may be useful in clinical practiceThe role of oxidative stress in sperm DNA damageClinical, lifestyle, and metabolic contributorsCan DNA fragmentation be improved? Where supplements may fit — and their limitationsPractical TakeawaysSperm DNA fragmentation helps explain why semen analysis results and outcomes don’t always alignTesting can be useful, but it’s only part of the picture — the focus is on what’s driving it and what can be improvedImproving overall health remains central — including diet quality, body composition where relevant, sleep, and reducing exposures like smoking, alcohol, and heatClinical issues such as varicocele or inflammation should be assessed and managed appropriatelyTargeted supplementation may play a role in some cases, but the evidence is mixed and not outcome-drivenIn situations like unexplained infertility, recurrent pregnancy loss, or failed treatment, more advanced testing may be worth discussing with a clinicianDisclaimerThis podcast is for general education only and does not replace individual medical or nutrition adviceIf you’re navigating fertility concerns or treatment, speak with your healthcare teamLinksWebsite: axisdietetics.comInstagram: @axisdietetics

Episode SummarySemen analysis provides a set of numbers, but those numbers are often misunderstood. In this episode, Men’s Fertility Dietitian Alex Hardy explains how to interpret the key parameters — sperm count, motility, and morphology — and why they need to be viewed together rather than in isolation.We break down what each parameter represents, how reference ranges are defined, and why results don’t always align neatly with fertility outcomes. This episode focuses on helping men move beyond confusion and use their results as a starting point for informed decision-making.What You’ll LearnWhat sperm count, motility, and morphology actually measureWhy semen analysis does not provide a single “fertility score”How each parameter reflects a different aspect of sperm functionWhy results must be interpreted together, not individuallyHow WHO reference ranges are defined and what they mean in practiceWhy semen analysis results can vary over timeWhat semen analysis does — and does not — tell us about fertilityKey TakeawaysSemen analysis is a screening tool, not a diagnosisSperm count, motility, and morphology reflect different biological processesNo single parameter determines fertility on its ownReference ranges are statistical, not pass–fail cut-offsResults can vary, so repeat testing is often neededSemen analysis provides useful information, but not the full picturePractical TakeawaysAvoid over-interpreting a single resultLook at patterns across parameters, not individual numbersUnderstand that “normal” does not necessarily mean optimalConsider repeat testing if results are borderline or unexpectedFocus on modifiable factors such as diet, lifestyle, sleep, and overall healthWhat’s NextIn the next episode, we look at one of the key limitations of standard semen analysis — sperm DNA fragmentation — and when more advanced testing may be useful.DisclaimerThis podcast is for general education only and does not replace personalised medical or healthcare advice.

Many couples spend months wondering whether something might be wrong. In this episode, Alex explains when fertility testing is actually recommended, when it may be worth doing earlier, and how semen analysis fits into the bigger picture.We cover what the test involves, what the results can and can’t tell you, and why repeat testing is sometimes needed.This episode marks the shift from foundational lifestyle factors into the clinical side of fertility assessment.What You'll LearnWhen fertility testing is typically recommendedSituations where earlier testing may be appropriateWhat a semen analysis involvesWhat sperm concentration, motility, and morphology representWhy semen analysis is not a pass–fail testWhy results can vary and when repeat testing is neededThe limitations of semen analysis and what it doesn’t measurKey TakeawaysMale factors contribute to around 50% of infertility casesTesting men early helps build a complete fertility pictureA semen analysis is a useful first-line test, not a definitive answerResults reflect a snapshot in time and can change“Normal” results do not necessarily mean optimal fertilityTesting replaces uncertainty with useful informationPractical PointsWhen to consider testingAfter 12 months of trying without pregnancyAfter 6 months if the female partner is over 35Earlier if there are known risk factors (injury, surgery, chemotherapy, infections, hormonal issues)Or simply to reduce uncertainty and guide next stepsWhat to expectSample collected at home or pathology2–5 days abstinence beforehandLab assesses count, motility, and morphologyHow to interpret resultsNot pass–failBased on population reference rangesShould be considered alongside clinical contextBig PictureA semen analysis is a starting point.It provides useful information about sperm health, but it doesn’t capture everything, including aspects like DNA integrity or actual fertilisation potential.The goal isn’t to assign blame.It’s to gather information that helps guide decisions.And importantly, it brings men into the fertility conversation earlier, where they should have been all along.DisclaimerThis podcast is for general education only and does not replace personalised medical or healthcare advice.

Episode overviewSleep is often overlooked when people think about fertility, yet it plays an important role in the hormonal environment that supports sperm production.In this episode, Alex explains how sleep patterns influence testosterone rhythms, why consistent sleep helps regulate key hormonal signals, and how disrupted sleep can gradually shift the environment sperm develop in.This episode continues the foundation series on sperm health, helping men understand how everyday habits influence fertility long before testing or treatment decisions come into the picture.In this episode, we cover:How sleep influences testosterone rhythms in menWhy hormonal signalling during sleep supports sperm productionWhat research suggests about sleep restriction and testosterone levelsThe connection between sleep disruption and semen parametersHow alcohol can indirectly affect sperm health through its effects on sleepCommon lifestyle patterns that shorten or disrupt sleepPractical habits that support consistent, restorative sleepKey takeaways:Sleep plays an important role in regulating the hormonal signals that support sperm productionTestosterone follows a daily rhythm closely linked to sleep patternsRegular sleep disruption may shift the hormonal environment sperm develop inAlcohol can impair sleep quality, which may indirectly affect sperm healthConsistent sleep patterns and adequate sleep duration help support reproductive healthSleep is rarely the only factor affecting fertility. But across the weeks when sperm are developing, it quietly shapes the hormonal environment those cells are exposed to.Practical strategies discussed:Keep sleep timing relatively consistent from night to nightAim for around 7–8 hours of sleep per nightProtect the later part of the night when deeper and REM sleep occurBe mindful of habits that repeatedly disrupt sleep, such as late-night alcohol or heavy screen useFocus on patterns across weeks rather than worrying about occasional poor sleepWho this episode is for:Men planning pregnancy or supporting a partnerMen preparing for fertility testing or IVFPartners looking for clear, realistic guidanceClinicians seeking aligned, referral-safe education for patientsWhat’s next:In the next episode we begin exploring the clinical side of fertility — when men should actually get tested and how to make sense of semen analysis results.DisclaimerThis podcast is for general education only and does not replace personalised medical or nutrition advice.If you are trying to conceive or undergoing fertility treatment, discuss your individual situation with your healthcare team.

Does alcohol actually need to be eliminated when trying to conceive — or is that an oversimplification?In this episode, Alex breaks down how alcohol influences sperm health, why timing and drinking patterns matter, and what men can realistically do to reduce risk without aiming for perfection. This is a practical, evidence-based discussion focused on sustainable changes rather than all-or-nothing rules.In this episode, we cover:• How alcohol affects the environment sperm develop in• The role of hormones and oxidative stress• Why timing matters during the 12-week sperm development window• Abstinence versus reduction — and when each approach makes sense• Practical strategies to reduce alcohol exposure without disrupting life• How alcohol, sleep, and recovery are connectedKey takeaways:• Alcohol doesn’t switch fertility on or off — it shifts the environment sperm develop in• Total drinking volume matters, but patterns and timing often drive risk• Regular heavy or binge-style drinking has a greater impact than occasional drinking spread out over time• Changes made in the 12 weeks before conception, testing, or treatment matter most• Sustainable reduction often delivers more benefit than short-term perfectionAlcohol isn’t a pass–fail test for fertility.It’s an exposure you can meaningfully reduce.Practical strategies discussed:• Focus on both how much and how often alcohol shows up• Avoid stacked nights and frequent heavy sessions• Be mindful of late-night drinking due to its impact on sleep and recovery• Prepare simple, honest responses for social situations• Replace alcohol as a stress outlet with other ways to unwindWho this episode is for:• Men planning pregnancy or supporting a partner• Men preparing for fertility testing or IVF• Partners looking for clear, realistic guidance• Clinicians seeking aligned, referral-safe education for patientsWhat’s next:In the next episode, we explore sleep, hormones, and testosterone — and how lifestyle inputs like alcohol and stress begin showing up in test results and treatment decisions. Up to now, the series has focused on foundations. From here on, those foundations begin intersecting with the clinical side.DisclaimerThis podcast is for general education only and does not replace personalised medical or nutrition advice.

Supplements are widely used in men’s fertility, but they’re often approached as a shortcut rather than a tool. In this episode, Alex explains where supplements actually fit, why results can be inconsistent, and how clinicians think about supplementation as part of a broader strategy that starts with food, lifestyle, and comprehensive assessment. The focus is on context, safety, and targeted use, not generic protocols.Why supplements are often misunderstood in men’s fertilityWhy motivated men start supplements early, and why that can inflate expectationsWhy “food first” is a sequencing decision, not an anti-supplement stanceThe three questions clinicians use to decide whether supplements belong (gap, mechanism, context)Why these decisions shouldn’t be guesswork, and the role of nutrition assessmentDose, timing, and duration, and why stacking can quietly lead to excessWhy the evidence can look mixed, and what study limitations mean in practiceA simple supplement audit you can do today to check overlap and dose creepWhy targeted supplementation tends to make more sense than blanket approachesSupplements are tools, not solutions. They tend to work best when used selectively, for a clear reason, on top of solid foundations.In the next episode, we’ll look at alcohol and sperm health, including what the evidence actually says and what changes are worth making.This podcast is for general education only and is not a substitute for individual medical advice.

Men’s fertility is often discussed in simplified, reassuring ways that don’t tell the full story. In this episode, Alex breaks down the most common misconceptions that can quietly undermine fertility outcomes, even when men feel they’re doing everything right.This episode focuses on understanding risk, timing, and preparation, not blame or guarantees.In this episode, we cover:Why fertility is often framed as pass/fail, and why thatcauses problemsWhy “normal” semen results don’t always mean optimalpreparationHow male fertility changes with age, and why riskaccumulates quietly over timeWhy lifestyle factors matter earlier than most men realiseWhy IVF and ICSI don’t remove the importance of spermqualityThe difference between control and certainty in men’sfertilityKey takeawayMen don’t control fertility outcomes, but they do influence risk. Understanding that distinction is the foundation for better timing, preparation, and decision-making.What’s nextIn upcoming episodes, we’ll start unpacking what actually helps, what matters when, and how men can approach fertility in a more proactive, informed way.DisclaimerThis podcast is for general education only and is not a substitute for individual medical advice.
