In the evolving world of fertility treatments, embryo freezing has emerged as one of the most impactful innovations in improving IVF success. Whether you’re delaying parenthood for personal or medical reasons, or navigating multiple IVF cycles, this technique gives hopeful parents more flexibility and control. At SCI IVF Hospital, we use the most advanced cryopreservation methods to help individuals and couples maximize their chances of pregnancy.
What Is Embryo Freezing?
Embryo freezing, also known as embryo cryopreservation, is the process of preserving fertilized eggs (embryos) at sub-zero temperatures for future use. After eggs are retrieved and fertilized through IVF or ICSI, the healthiest embryos are selected for transfer, while the remaining viable ones can be frozen.
This allows couples to attempt multiple pregnancies from a single egg retrieval cycle and reduces the physical and emotional strain of starting over.
Why Is Embryo Freezing Important?
The role of freezing embryos in an IVF journey goes beyond just storage—it’s about improving outcomes and providing backup:
- Increases Pregnancy Chances: Multiple frozen embryos give more opportunities for successful implantation across different cycles.
- Reduces Cost and Stress: With frozen embryos available, there’s no need to go through the full stimulation and egg retrieval process again.
- Preserves Fertility for Later: Especially useful for women undergoing cancer treatment, egg freezing or embryo preservation allows for future pregnancy.
- Facilitates Preimplantation Testing: Frozen embryos can be genetically screened for disorders before transfer, increasing the chances of a healthy pregnancy.
When Is Embryo Freezing Recommended?
At SCI IVF Hospital, our fertility specialists may recommend embryo freezing in several situations:
- Excess Embryos in IVF: When more embryos are created than needed in a single IVF cycle.
- Medical Treatments: For patients undergoing chemotherapy or surgeries that could impact fertility.
- Age-Related Fertility Planning: For individuals wanting to delay pregnancy but preserve younger, healthier embryos.
- Multiple Embryo Transfers: If the first transfer isn’t successful, frozen embryos can be used in later cycles without restarting the process.
Success Rates of Frozen Embryo Transfers
Many people assume that fresh embryos offer better outcomes, but current data shows otherwise. In many cases, frozen embryo transfers (FET) are equally effective—or even more successful—than fresh transfers. At SCI IVF Hospital, our freezing protocols use vitrification, a rapid freezing method that prevents ice crystals from forming and damaging the embryo.
This process results in:
- High Survival Rates: Over 90% of embryos survive the thawing process.
- Comparable Implantation Rates: FET outcomes now closely match those of fresh embryo transfers.
- More Flexibility: You can plan the transfer when your body and mind are best prepared.
Emotional Benefits of Freezing Embryos
Beyond the clinical data, embryo freezing offers peace of mind:
- Gives Hope: Knowing you have multiple chances without undergoing stimulation again can ease anxiety.
- Reduces Pressure: Couples are not forced to make immediate decisions about how many embryos to transfer at once.
- Supports Long-Term Family Planning: Frozen embryos can be used years later, allowing for sibling pregnancies using the same genetic material.
