In this episode, Prof Chapman tackles one of the most heartbreaking questions in fertility, why miscarriages keep happening. Responding to a listener who has faced four losses across natural and IVF conceptions, he walks through the biggest culprit, genetic abnormalities in the embryo, and explains why age and egg quality sit at the centre of it all. He unpacks the other hidden causes worth investigating, from chromosome translocations carried by healthy parents to fibroids, scar tissue, and abnormalities in the shape of the womb. Along the way he covers the surprising fertility effects of COVID, the global decline in birth rates, and why more women in their early 30s are choosing to freeze their eggs while quality is still on their side. Practical, honest, and deeply reassuring for anyone navigating the road to a baby.
