About Embryo Freezing

What Is Embryo Freezing?

Embryo freezing is a fertility preservation technique that involves freezing and storing fertilised eggs (embryos) for future use. These embryos are typically created through IVF (in vitro fertilisation) or ICSI (intracytoplasmic sperm injection) treatment and can be preserved for future pregnancy attempts.

Under current Singapore Ministry of Health (MOH) guidelines, up to two embryos may be transferred for women under 40 years of age, while up to three embryos may be transferred for women aged 40 and above. Any additional suitable embryos may undergo embryo freezing and be stored for future Frozen Embryo Transfer (FET) cycles.

Embryo freezing and storage can provide greater flexibility for family planning and may reduce the need for repeated ovarian stimulation and egg retrieval procedures in future treatment cycles.

A fertility specialist at Seng's OG Clinic can advise whether embryo freezing is suitable for your circumstances, explain the embryo freezing process, and discuss the benefits, limitations and considerations associated with long-term embryo storage.

Patient Eligibility

Who is Suitable for Embryo Freezing?

Women considering fertility preservation and future family planning

Embryo freezing may be suitable for patients who have additional good-quality embryos remaining after an IVF or ICSI treatment cycle. The decision to proceed with embryo freezing and storage depends on the number, quality and developmental stage of the embryos, as embryos with poor viability may be less likely to survive the freezing and thawing process.

If a treatment cycle is unsuccessful or if patients wish to expand their family in the future, frozen embryos can be thawed and used in a Frozen Embryo Transfer (FET) cycle without the need to repeat ovarian stimulation and egg retrieval procedures.

A fertility specialist can assess your suitability for embryo freezing, explain the expected outcomes, and discuss how embryo storage may support your future family-planning goals.

Embryo Freezing Outcomes

Success Rates of Embryo Freezing

Embryo freezing generally offers higher success rates than egg freezing because embryos consist of multiple cells that are more resilient to the freezing and thawing process. While some cells may be affected during cryopreservation, many embryos successfully survive thawing and continue normal development.

Advances in embryo freezing technology, particularly vitrification, have significantly improved embryo survival rates and pregnancy outcomes following Frozen Embryo Transfer (FET). As a result, embryo freezing and storage have become an important option for fertility preservation and future family planning.

Your fertility specialist can discuss the expected success rates of embryo freezing based on your age, embryo quality, and individual treatment circumstances.

The Procedure

Embryo Freezing Procedure

Safely preserve healthy embryos for future pregnancy opportunities.

STEP 01

Following IVF or ICSI treatment, multiple eggs may be collected and fertilised to create embryos. After embryo development is assessed, one or more embryos may be transferred, while any additional good-quality embryos can undergo embryo freezing for future use.

01
STEP 02

These frozen embryos can later be thawed and used in a Frozen Embryo Transfer (FET) cycle, providing another opportunity for pregnancy without the need to repeat ovarian stimulation and egg retrieval procedures.

02
STEP 03

Embryo freezing and storage offers flexibility for future family planning and is widely used as a fertility preservation option. In many cases, pregnancy outcomes from frozen embryo transfers are comparable to, or may even exceed, those achieved with fresh embryo transfers.

03
STEP 04

Your fertility specialist can advise whether embryo freezing is suitable for your treatment plan and discuss the expected outcomes based on your individual circumstances.
