How Pregnancy Chances Change With Age

The Biological Reality

Fertility peaks in your 20s (approx 25% per cycle) and begin to decline gradually in your 30s. After age 35, the decline in both egg quantity and chromosomal quality begins to accelerate.

How to Improve Odds

  • Track ovulation precisely with BBT or OPKs
  • Maintain a healthy BMI (19-24)
  • Reduce chronic high stress
  • Avoid smoking and excessive toxins
