This audiobook is narrated by an AI Voice. Your grandfather had more testosterone at 65 than you do at the peak of your life.

That is not a metaphor. That is what the data shows.

Since the 1970s, average male testosterone levels have fallen by more than half. Sperm counts have dropped by nearly sixty percent. The World Health Organization quietly lowered its definition of a normal sperm count — not because science changed, but because too many men were failing the old standard.

Something did this. Something that arrived in daily life at roughly the same time the numbers started falling.

It is in your shampoo. It is in your deodorant. It is in the plastic container you heated in the microwave this morning. It is in the lining of food tins, the foam of your sofa, the air freshener in your bathroom. These are not conspiracy theories. They are peer-reviewed findings from reproductive endocrinology, toxicology, and epidemiology that have accumulated for decades without ever reaching the men they are about.

The Unmanning of Modern Men follows two men — Owen, who started reading studies at midnight after his body stopped feeling like his own, and Marcus, who resisted until his son sat in a specialist's office and the door he had kept shut would not stay shut anymore. Through their story, this book explains what synthetic chemicals actually do to testosterone production, sperm quality, and foetal development — in plain language, without jargon, without agenda, and without pretending the problem is smaller than it is.

You were not warned. The system was not built to warn you. But you are in the experiment whether you know about it or not.

This book is the briefing you should have been given twenty years ago.
