Dr. Mills is joined by reproductive urologist Dr. Jim Smith, a longtime colleague and leading expert in male fertility and men’s health. Together, they break down what a semen analysis actually measures, why quality and timing matter, and why men shouldn’t wait a year into the fertility journey to get checked. Dr. Smith also explains sperm cryopreservation — who should consider banking, how long it lasts, and why access remains a major barrier. Plus, they'll bust the biggest myths about what “kills” sperm, explain why semen can be a window into overall health, and offer a surprisingly practical prescription for better fertility.
