Three different fertility doctors independently recommended CoQ10 and L-carnitine to patients to support mitochondrial health in sperm and eggs, improving motility and quality.

Huberman frames fertility nutrition around one core tension: adequate calories are essential, but both excess and deficit are harmful, and body composition is the lens. For men, Dr. Kyle Gillett's guidance draws a key threshold at 15% body fat — above that, cut to reduce inflammation and improve testosterone; below that, avoid sustained deficits that suppress testosterone. [1] — Andrew Huberman "Any exogenous testosterone — even a low 'microdose' under 100mg/week — will suppress sperm count through negative feedback on the testes. H…" 52:40 He delivers what he describes as a critical, repeated point: any exogenous testosterone, even microdoses under 100mg/week, will reduce sperm count through negative feedback. HCG (~500 IUs three times per week) can partially offset this, but reversal isn't guaranteed — if fatherhood is a remote possibility, freeze sperm first. For women, the same bidirectional principle applies: excess body fat drives inflammation and impairs fertility, while too little causes menstruation to cease. The dietary prescription — endorsed by multiple fertility experts — is a low-inflammation diet: lean proteins, fresh produce, monounsaturated fats, fermented low-sugar foods. [2] — Andrew Huberman "A Stanford study found that eating ~4 daily servings of low-sugar fermented foods (kimchi, sauerkraut, Bulgarian yogurt) significantly redu…" 58:50 He cites the Stanford Sonnenberg/Gardner study showing ~4 daily servings of fermented foods (kimchi, sauerkraut, yogurt) significantly reduce inflammatory markers, whereas high-fiber diets increase inflammation in some people. On supplementation, three separate fertility doctors independently recommend L-carnitine and CoQ10 for their patients — both support mitochondrial health in sperm and eggs, improving motility and quality.
A Stanford study found that eating ~4 daily servings of low-sugar fermented foods (kimchi, sauerkraut, Bulgarian yogurt) significantly reduced multiple inflammatory markers. High-fiber diets actually increased inflammation in some participants — a finding that reframes how we think about gut health and fertility.
A Stanford study found that eating ~4 servings/day of low-sugar fermented foods significantly reduced multiple inflammatory markers, whereas high-fiber diets raised inflammation in some participants.
The large-scale HRT studies that concluded hormone therapy was dangerous or ineffective for menopause were apparently flawed in design and conclusion. Starting therapy early enough — in perimenopause or early menopause — shows significant benefits that were buried. Anxiety during hormonal transition is mechanistically well-founded and should prompt a conversation with your doctor.
Revised analysis of large-scale hormone replacement therapy studies shows that starting HRT early enough in perimenopause or menopause produces beneficial effects that were missed in the original, flawed conclusions.
Despite predictions that AI would eliminate radiologists, the Mayo Clinic's radiology staff grew 55% after AI arrived at reading scans.
In 2025, radiology was the second-highest paid medical specialty in America, with average incomes 48% higher than a decade ago.
A study across 3 hospitals found radiologists spent only 36% of their time reading scans — the part AI can do — with the rest being human judgment.
Robert Greene notes that one in six Americans is on some form of drug to deal with depression, suggesting a deep societal disconnection from meaningful experience.
Spencer Greenberg and Jeremy Stevenson analyzed almost 500 self-improvement techniques and found they all reduce to just 12 underlying psychological drivers.
Cold exposure has good short-term alertness benefits but the evidence base for long-term health benefits is much weaker than popularly believed.
In a randomized study of 20 habit-formation techniques run on hundreds of people, almost none of the techniques produced statistically meaningful results.
People given a tiny-habit fallback option (e.g. 10 squats instead of gym) were actually MORE successful at completing the full habit, not less.
The most effective habit-formation technique was 'habit reflection' — recalling a past successful habit, writing down what helped, then applying those lessons to a new habit.
