Dr. Gabrielle Lyon sits down with fertility specialist Dr. Natalie Crawford to tackle the urgent rise in infertility across both men and women. Dr. Crawford, an advocate for proactive reproductive health, reveals why inflammation is hijacking your fertility and why the old dogma that "age is the only factor" for egg quality is dangerously incomplete.

They cover critical, actionable steps—from the most important lifestyle changes you can make before IVF, to the toxic habits that are directly lowering sperm counts and causing miscarriages. Learn the three essential fertility awareness methods (FAMs) and what your doctor is missing when they check your thyroid.
