INSIGHT

Fertility Is A Window Into Whole-Body Health

  • Fertility acts as a sentinel health marker; infertility increases long-term risks of stroke, heart disease, and metabolic illness.
  • Viewing fertility as overall-health information reframes prevention and earlier evaluation.
ADVICE

Best Egg-Freezing Window: Early 30s

  • Consider egg freezing around ages 31–33 for best ROI and higher egg yield while balancing cost and life plans.
  • If you want children later, test and discuss options early rather than waiting until fertility problems appear.
ADVICE

Three Big Levers To Lower Inflammation

  • Reduce inflammation by prioritizing sleep, building muscle, and improving diet as primary interventions.
  • Aim for 7–9 hours sleep, resistance training three times weekly, and a fiber-rich whole-foods diet.
