Treatment Overview
Blastocyst transfer is a highly refined stage of in vitro fertilization (IVF), where embryos are cultured in the lab for 5–6 days after fertilization until they reach the blastocyst stage—a point at which they are more developed and have a higher potential for successful implantation. In Korea, blastocyst transfer is often integrated with donor egg IVF programs to maximize success rates, especially for women facing complex fertility issues. The procedure is carried out in advanced embryology labs equipped with next-generation incubators, time-lapse imaging, and AI-assisted selection systems to ensure only the most viable embryos are chosen for transfer.
Purpose & Benefits
The goal of blastocyst transfer is to improve implantation success and reduce the risk of multiple pregnancies. By allowing embryos to mature further before transfer, doctors can identify those most likely to result in a healthy pregnancy. Benefits include:
- Higher success rates per transfer compared to day 3 embryo transfers.
- Lower miscarriage risk due to advanced selection of embryos.
- Improved synchronization between embryo development and the uterine lining.
- The ability to perform genetic testing (PGT-A) before transfer to screen for chromosomal abnormalities.
For patients using donor eggs, this step further enhances the already strong outcomes, combining the advantage of young donor eggs with scientifically verified blastocyst selection.
Ideal Candidates
Blastocyst transfer is ideal for:
- Women undergoing donor egg IVF or traditional IVF cycles.
- Patients with previous failed IVF attempts or recurrent pregnancy loss.
- Couples desiring single embryo transfer with a high chance of success.
- Those wishing to minimize the risk of multiple pregnancies while maintaining excellent pregnancy outcomes.
It is particularly recommended for international patients seeking highly successful, evidence-based fertility treatments in Korea.
Possible Risks & Complications
Though generally safe, potential risks include:
- Failure of embryos to develop to the blastocyst stage (rare in top Korean labs).
- Slightly lower number of embryos available for freezing.
- Minimal risk of infection or uterine irritation after the transfer procedure.
However, Korea’s advanced IVF labs use optimized culture conditions and real-time embryo monitoring to ensure optimal development and minimize complications.
Surgical Techniques Used
Korean fertility specialists utilize state-of-the-art laboratory techniques, including:
- Time-Lapse Embryo Culture Systems for continuous monitoring.
- AI-based Blastocyst Grading Algorithms for accurate selection.
- Laser-Assisted Hatching (LAH) to aid embryo implantation.
- EmbryoScope™ incubators that replicate the natural uterine environment.
- Vitrification and warming systems to preserve blastocyst viability for future cycles.
These innovations, combined with Korea’s precision-based medical protocols, contribute to high success and global recognition in reproductive technology.
Recovery & Aftercare
Blastocyst transfer is a quick, non-invasive procedure with no need for anesthesia. Patients can return to daily activities almost immediately but are often advised to rest for a few hours post-transfer. Korean fertility centers provide detailed post-transfer care, including hormonal support, follow-up ultrasound checks, and early pregnancy monitoring. Emotional support and personalized nutrition guidance are also offered to ensure the best possible outcomes.
Results & Longevity
Blastocyst transfer in Korea demonstrates exceptional success rates, often ranging between 60% and 80% for donor egg IVF cycles. Pregnancies achieved via this method are typically strong and healthy, with a reduced likelihood of miscarriage. The longevity of results is comparable to natural conception, ensuring normal gestational progress once pregnancy is established.
Treatment Process in Korea
The Korean blastocyst transfer process follows an advanced, step-by-step approach:
- Fertilization of donor eggs with sperm in a state-of-the-art lab.
- Embryo culture and monitoring until the blastocyst stage (day 5–6).
- Optional preimplantation genetic testing (PGT-A).
- Transfer of one or two high-quality blastocysts into the uterus.
- Cryopreservation of remaining viable embryos for future use.
Korean fertility centers employ integrated AI systems, smart-lab automation, and personalized treatment mapping to maximize embryo potential. Korea’s fertility technology, ethical donor matching, and streamlined international patient services make it one of the top global destinations for IVF and blastocyst transfer.
Cost Range
The cost for blastocyst transfer as part of a donor egg IVF package in Korea typically ranges from USD 13,000 to USD 25,000, depending on the clinic, donor program, and whether genetic testing or embryo freezing is included. Standalone blastocyst transfer (for existing frozen embryos) costs between USD 3,000 and USD 6,000. Many clinics offer all-inclusive packages for international patients, covering medication, donor coordination, accommodation, and follow-up services.
