All the Stats

All of the statistics I have found surrounding chromosomal abnormalities:

The risk of having a child with Trisomy is not higher than normal unless one or both parents have chromosomal abnormalities. Our chromosome test results were normal, so we have an average risk.

The risk of having a child with chromosomal abnormalities does increase with age, from 1/526 at age 20 to 1/8 at age 49. At age 27 my risk was 1/455, so still fairly low, but somebody always has to be the ‘1’ in statistics.

About 95% percent of embryos with genetic problems are miscarried. Chromosomal anomalies are responsible for about 60% of early miscarriages.

About 1 in every 160 pregnancies ends in stillbirth. Chromosome disorders account for 15-20% of all stillbirths.

Only 2 -3% of live-born infants have chromosomal abnormalities.
