TESTOSTERONE & MALE HEALTH

The Hormone That Defines Masculine Biology — and Is Under Attack.

Average testosterone levels in Western men have fallen by 20-25% over the past three decades — a decline that cannot be explained by ageing alone. The culprits are environmental: xenoestrogens from plastics, phthalates in personal care products, dietary seed oils that suppress steroidogenesis, nutritional deficiencies in zinc and vitamin D, EMF radiation from mobile phones carried in trouser pockets, and chronic psychological stress driving cortisol that directly suppresses testicular Leydig cell function. Low testosterone drives depression, infertility, obesity, cardiovascular disease, cognitive decline, and loss of vitality.
