Chromosomal balanced translocation, what is the success rate of IVF for the third generation

Patient's question:

I had two miscarriages in the Qing Palace, both around 52 days. After examination, the female has a balanced translocation on chromosome 6 and 7, while the male is normal.

Doctor's answer:

Hello! The female has a balanced translocation. Theoretically, the eggs produced are 1/18 normal, 1/18 balanced, and the rest are unbalanced. This can lead to an increased rate of early miscarriage in the female and also an increased risk of congenital defects in the fetus.
