His claim is correct. We have a fertility crisis. > 62% sperm count drop globally 1973 - 2018 > 23% drop in just 16 years > rate of decline accelerating > dropping 2.64% per year since 2000 I explain below how to improve yours. I've been working on improving my fertility markers for the past two years. They are elite for a early 20 something (I'm 48). Total motile count: 411 million Motility: 64% Morphology: 12% Concentration: 212 million Count: 642 million To put these numbers into perspective: the WHO considers a motile count above 42 million as normal, mine is 411 million, nearly 10x. And a normal concentration is 16 million (mL), mine is 212 million (mL). These personal-best fertility markers coincided with my first-in-human test result showing zero microplastics in my semen. Studies have shown 100% of men have microplastics in their semen. Microplastics hurt sperm. Human studies show the impact of various types of plastic, associated chemicals, and other toxins on male fertility: + 60% fewer normal shaped sperm (from PFAS) + 5x higher odds of low sperm count (from PTFE) + 10% lower sperm concentration (from PTFE) + 15% lower swimming ability (from PTFE) + 41% lower swimming ability (from PET) + 12% lower sperm swimming ability (from BPA) + 3x higher odds of low sperm count (from Phthalates) + 2x higher odds of poor swimming (from Phthalates) How to improve your fertility: > 7 to 9 hours of sleep, consistent bed and wake times > exercise: cardio fitness, strength, and muscle > reducing body fat and build lean mass > avoid alcohol, tobacco, and cannabis; each independently reduces sperm concentration, motility, and morphology, with cannabis also affecting sperm methylation. > cut junk food, added sugars, and excessive saturated fats > eat an anti-inflammatory, anti-oxidant diet (Mediterranean and green-Mediterranean): polyphenols, fiber, olive oil and other MUFAs, omega-3s (algal, fish, walnuts), plant protein, fresh veggies. > get full micronutrient coverage: zinc, selenium, folate, vitamins C, E, and D (blueprint solves this). > manage stress and cortisol load; chronic stress lowers testosterone and impairs spermatogenesis. Things I'm doing: 1. Sauna (dry). My toxin blood panel confirms sauna clears plastic related chemicals: BPA, phthalates, PFAS, flame retardants, pesticides. The plastic particles themselves are too big to sweat out directly. Heat may activate other clearance routes: bile flow through the liver, the cell's internal cleanup system, and the gut barrier. Humans have almost no enzymes that can break plastic apart, so the body has to physically push it out. 2. Reverse osmosis water filter. Drinking water is likely a major source of microplastic getting into your body. A reverse osmosis filter pushes water through a very tight membrane and strains the particles out. I filter everything I drink. 3. Trying to rid my environment of the big plastic items: cutting boards, cups, plates, food storage containers, non-stick pans, cling wrap, tea bags, water bottles, kitchen utensils, kettles, and synthetic clothing. Note, as hard as I try, I'm always finding new plastic things in my life. This can be all-consuming thing so try to just knock out the big ones. The studies: > meta-analysis with total 42,935 men; significant decline in both sperm concentration and total sperm count among men from Western countries, with total sperm count by about 59%, between 1973 and 2011. > A follow-up global meta-analysis, expanded the dataset to 223 studies and 57,168 men found the drop in sperm count was not only a Western phenomenon > total sperm count dropped by 62% globally between 1973 and 2018, including in men from South America and Asia. The rate of decline has also accelerated since 2000, reaching approximately 2.64% per year. > CDC data also showed US fertility rates peaking at the replacement level of 2.12 births per woman in 2007, then taking a sharp downward turn by 23% down to 1.62 in 2023.
