Embryo cryopreservation uses vitrification technology to freeze and store embryos for future use. China's advanced reproductive centers employ state-of-the-art vitrification protocols achieving survival rates above 95%. This technology allows patients to preserve fertility, plan future pregnancies, or store surplus embryos from IVF cycles at a fraction of Western costs.
Embryo Development & Selection
Following IVF or ICSI, embryos are cultured to the blastocyst stage (day 5-6) and graded by embryologists for quality and viability.
Duration: 5-6 daysVitrification Process
Selected embryos are rapidly frozen using vitrification — an ultra-rapid cooling technique that prevents ice crystal formation and preserves cellular integrity.
Duration: 1-2 hoursCryogenic Storage
Frozen embryos are stored in liquid nitrogen tanks at -196°C in secure, monitored facilities with backup systems and 24/7 surveillance.
Duration: Ongoing (annual renewal)Thawing & Transfer (when ready)
When the patient is ready, embryos are carefully thawed, assessed for viability, and transferred to the prepared uterus during a natural or medicated cycle.
Duration: 1-2 hours- Preserves fertility for future family planning
- Over 95% embryo survival rate with vitrification
- Avoids repeated ovarian stimulation cycles
- Annual storage fees significantly lower than Western countries
- Small percentage of embryos may not survive thawing
- Long-term storage requires ongoing fees and commitment
- Regulatory requirements for storage and use in China
- Emotional considerations around frozen embryo decisions
