Concept & Option Breakdown

Standard Reference Verified

Pronuclear Transfer (PNT) is an assisted reproductive technology (mitochondrial donation technique / three-parent IVF) designed to prevent the transmission of maternally inherited mitochondrial DNA (mtDNA) disorders to offspring. In this technique, the pronuclei containing nuclear DNA are transferred from a fertilized egg of the mother into an enucleated donor embryo with healthy mitochondria.
