The Fertility Test Most Men Are Never Offered | Dr Michael Eisenberg and Dr Natalie Crawford

In this episode, host Simon Hill speaks with urologist Dr Michael Eisenberg and reproductive endocrinologist Dr Natalie Crawford about male fertility, often overlooked despite contributing to half of infertility cases. They explain that ejaculating normally does not guarantee fertility, and a semen analysis is the critical first step. The conversation reveals that sperm health may be a powerful window into overall wellness, with one Danish study linking semen quality to lifespan. They also discuss testosterone therapy as a temporary contraceptive, the alarming global decline in sperm counts driven by endocrine disruptors and lifestyle, and how sperm can regenerate within three months, making it a rapidly improvable health metric.
