The science of ultra-rapid freezing
Traditional slow-freezing methods caused ice crystal formation that damaged cells. Vitrification cools cells at over 20,000°C per minute, achieving a glass-like state without crystallisation. Survival rates approach 95+ percent for both eggs and embryos.
Where we use vitrification
- Surplus IVF embryos for future cycles
- Elective egg freezing for fertility preservation
- Medical fertility preservation (before chemotherapy)
- Donor egg programmes
- Banking sperm before vasectomy or oncological treatment
- Storing embryos when fresh transfer is suboptimal (high progesterone, OHSS risk)
Outcomes from vitrified material
Long-term follow-up of children born from vitrified eggs and embryos shows no increase in congenital anomalies or developmental issues compared to fresh-cycle babies. Vitrification is now considered the cryopreservation standard.
