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.

Frequently asked
Dr Patel leads fertility care at Balaji Horizon, integrating reproductive surgery and IVF into a single plan — ethical, evidence-based and individualised, with realistic expectations and no overpromising of success.
Individualised IVF and fertility planning with honest, evidence-based counselling — and realistic expectations from the very first consultation.
Why vitrification matters for your treatment
Vitrification is an ultra-rapid freezing method that has largely replaced older slow-freezing. By cooling eggs and embryos so quickly that ice crystals cannot form, it gives much higher survival rates on thawing — which is why frozen-embryo transfers today perform so well.
What it makes possible
Reliable freezing underpins several modern, safer strategies: a freeze-all cycle to avoid transferring into an over-stimulated uterus, banking embryos across cycles for cumulative chances, and fertility preservation by freezing eggs before age or treatment reduces the reserve.
How dependable is it
Survival of vitrified blastocysts is high in a good laboratory, and pregnancy rates from frozen transfers are at least comparable to fresh in most situations. The quality of the embryology lab is the single biggest variable, which is why technique and staffing matter as much as the method itself.
Honest framing
Freezing does not improve an embryo’s underlying quality — it preserves what is there. We are clear about that, and about realistic survival and success figures for your own situation.
