GENERATION is a collection of thirty-five essays exploring the dynamic frontiers of the biology and technology of human reproduction.

Once a neglected corner of physiology, reproductive science now shapes medicine, agriculture, and society in profound ways. From contraception and IVF to genetic screening, reproductive cloning, and the ethics of embryo research, the field has expanded with remarkable speed during the past half-century.

Drawing on a lifetime of research and teaching, I examine the science behind these advances while reflecting on their wider implications. The essays move from laboratory discoveries to clinical practice, from philosophical questions to personal encounters, and from the pioneers who laid the groundwork to the technologies transforming fertility today.

Written for scientists, clinicians, and curious readers alike, Generation offers a clear-eyed exploration of how humanity has learned not only to understand reproduction—but increasingly to shape it.

The essays are extracted from my Substack What’s Hot in Fertility? and deeply edited with extra articles. Available as an eBook at Amazon. $3.95 (or equivalent currency) or free on Kindle Unlimited.
