Cytoplasmic Transfer: Then vs. Now 1997–2026 | INCIID
Cytoplasmic transfer was a pioneering IVF technique first performed in 1997, injecting donor cytoplasm into a patient’s egg to improve embryo development. This interactive guide explores the science behind cytoplasmic transfer — from how it works at the cellular level to why good eggs still fail, what heteroplasmy means for patients, and why regulatory and genetic concerns halted its adoption. Explore the evolution from the original 1997 procedure through today’s related techniques, MST and PNT.
