Treatment Overview
The CHA Embryo Freezing Program in Korea is one of the most advanced and trusted fertility preservation services available in Asia and beyond. Operated by CHA Fertility Center, a global leader in reproductive medicine, this program specializes in the vitrification and long-term cryostorage of embryos using next-generation technology.
CHA’s program integrates ultra-rapid freezing, AI-guided embryology, and biobank-grade cryogenic storage systems to ensure that every embryo maintains maximum viability, genetic stability, and developmental potential. Whether for IVF flexibility, family planning, or medical fertility preservation, the CHA Embryo Freezing Program provides safe, efficient, and scientifically optimized solutions for every patient.
Purpose & Benefits
The purpose of the CHA Embryo Freezing Program is to preserve high-quality embryos for future pregnancy, offering patients the flexibility to plan family-building at their preferred time.
Key benefits include:
- High embryo survival rate: Over 98% survival after thawing using CHA’s advanced vitrification systems.
- Long-term fertility flexibility: Allows embryo transfer months or years after IVF.
- Optimal timing for pregnancy: Enables transfer when the uterine environment is most receptive.
- Superior cryogenic stability: Prevents ice crystal formation and cellular damage.
- Integration with genetic testing (PGT-A/PGT-M): Ensures only chromosomally healthy embryos are preserved.
- Internationally accredited lab standards: CHA’s embryology laboratories meet ISO and CAP certification standards.
- Secure biobank environment: 24-hour temperature, nitrogen, and environmental monitoring for long-term safety.
Through this program, CHA provides an exceptional combination of science, precision, and compassionate reproductive care.
Ideal Candidates
The CHA Embryo Freezing Program is suitable for couples and individuals who wish to preserve their embryos for future use, whether for medical, personal, or logistical reasons.
Ideal candidates include:
- Couples undergoing in vitro fertilization (IVF) with surplus embryos.
- Women delaying pregnancy for career or personal planning.
- Patients preparing for cancer treatments or other medical procedures affecting fertility.
- Couples seeking to store embryos after genetic testing (PGT).
- Individuals using donor eggs or sperm in assisted reproduction.
- Families planning multiple pregnancies at different times.
This program is designed to support diverse reproductive needs while ensuring the highest possible embryo quality and safety.
Possible Risks & Complications
Embryo freezing is an extremely safe and well-established procedure. However, minimal risks exist:
- A very small number of embryos (typically <2%) may not survive the thawing process.
- Emotional or psychological stress related to IVF or delayed family planning.
- Rare equipment or storage malfunctions — effectively mitigated by CHA’s dual cryogenic backup systems.
CHA’s state-of-the-art laboratories use automated temperature sensors, redundant nitrogen tanks, and real-time monitoring alerts, ensuring complete safety for every stored embryo.
Techniques & Laboratory Innovations
The CHA Embryo Freezing Program combines decades of fertility research with global innovations in cryobiology and reproductive technology.
Core techniques include:
- Controlled Ovarian Stimulation & IVF: Eggs are fertilized and cultured under optimal lab conditions.
- Embryo Selection: Time-lapse imaging and AI-assisted embryo grading help identify the best-quality embryos.
- Vitrification (Flash Freezing): Ultra-rapid cooling prevents ice formation, maintaining cellular structure.
- Closed-System Freezing: Ensures sterile and contamination-free cryopreservation.
- Biobank Storage: Embryos are stored in cryogenic tanks at −196°C with continuous digital temperature logging.
- AI & Digital Management: CHA’s integrated system tracks each embryo with barcode identification for secure traceability.
- Smart Cryogenic Backup Systems: Automatic refilling and dual nitrogen storage to prevent environmental variation.
CHA’s fertility laboratories operate under Good Laboratory Practice (GLP) and ISO 9001 certification, ensuring medical excellence and global compliance.
Recovery & Aftercare
Recovery following embryo freezing involves minimal physical impact, as the procedure occurs after fertilization in the lab.
Typical aftercare recommendations:
- Rest after egg retrieval (if performed recently).
- Avoid intense physical activity for 1–2 days.
- Follow prescribed medications for hormonal balance.
- Attend follow-up consultations to discuss embryo reports and cryostorage confirmation.
- Maintain communication with fertility coordinators for future transfer planning.
CHA’s fertility programs include wellness and reproductive counseling, ensuring that both physical and emotional well-being are supported during the treatment journey.
Results & Longevity
The CHA Embryo Freezing Program has demonstrated outstanding success rates due to its precision vitrification and biobank management systems.
Clinical outcomes:
- Embryo survival rate post-thaw: 98–99%.
- Pregnancy rate with frozen embryo transfer (FET): 60–70% in women under 35.
- Live birth rate: Comparable to fresh embryo transfers.
- Storage longevity: Embryos remain viable for over 20 years in CHA’s biobank.
- Genetic integrity: Embryos retain full chromosomal stability throughout cryostorage.
These results place CHA among the world’s leading fertility institutions for cryopreservation outcomes.
Treatment Process in Korea
The CHA Embryo Freezing Program follows a structured, technology-driven, and patient-centered protocol designed for safety, precision, and long-term success.
Step 1: Fertility Consultation & Assessment
Comprehensive reproductive health evaluation, including hormone testing, ultrasound, and semen analysis.
Step 2: IVF Treatment & Embryo Creation
Eggs are retrieved and fertilized using IVF or ICSI methods in CHA’s advanced laboratories.
Step 3: Embryo Culture & Selection
Embryos are cultured for 3–5 days and monitored with AI-based imaging systems to determine quality.
Step 4: Vitrification (Embryo Freezing)
High-quality embryos are vitrified using CHA’s proprietary rapid-cooling system for maximum survival.
Step 5: Biobank Cryostorage
Embryos are transferred to CHA’s biobank facility with 24/7 digital monitoring, automated nitrogen systems, and secure backup power.
Step 6: Future Transfer
Embryos can be thawed and transferred during a patient’s optimal fertility window or at any future date.
