"The optimal age to freeze eggs is 19" by GeneSmith
Jean Smith, essayist and reproductive data analyst, argues for much earlier egg freezing and backs it with statistics. She explains why eggs age faster than the uterus and how waiting until the mid-30s harms outcomes. She breaks down IVF statistics, embryo screening limits, why stem-cell eggs are not an immediate fix, and gives a practical how-to and risk overview for freezing eggs.
