Male Infertility and the Exposome: How Heat, Air, Plastics, and Stress Add Up
Male FertilityEnvironmental Toxins
Male infertility rarely comes down to a single cause. Heat, air pollution, plastics, chronic stress, and disrupted sleep each nudge sperm quality in the wrong direction, and when they stack up across the roughly 74-day window it takes to produce sperm, the combined load can matter far more than any one exposure on its own.If you ask most men what causes fertility issues, they’ll name one thing. Testosterone. Stress. A chemical. Maybe “plastics.”What I see more often is a stack of exposures that all nudge sperm in the wrong direction.... Read more...
The Testicular Temperature Paradox: Why Your Body Keeps Sperm Cool and What Happens When It Can't
Sperm HealthClaims Examined
Your body keeps sperm cool because spermatogenesis requires a temperature of about 34°C, roughly 3 to 4 degrees below core body temperature, and when scrotal temperature rises above that threshold repeatedly, sperm production suffers. The effect is temporary and reversible, but recovery takes months rather than days.Your testicles hang outside your body for a reason. It's not a design flaw—it's a temperature regulation system that's been conserved across 200 million years of mammalian evolution. Human sperm production requires a consistent temperature of about 34°C (93°F), roughly 3 to 4 degrees... Read more...
