タイでの胚冷凍保存に最適なクリニックと費用をご発見ください2026

The standard method for embryo freezing in Thailand is vitrification, a high-tech flash-freezing technique. This rapid-cooling process uses cryoprotectants and specialized Cryotop devices to prevent ice crystal formation. Top Bangkok fertility centers maintain survival rates between 90% and 99% using these globally recognized protocols.

• Core technology: Vitrification uses ultra-rapid cooling to reach sub-zero temperatures in seconds.
• Storage equipment: Clinics commonly utilize Cryotop brand devices for secure, long-term embryo storage.
• Success rates: Post-thaw survival consistently reaches 90-99% in high-volume JCI-accredited laboratories.
• Laboratory standards: Thai embryologists often receive specialized training in Australia or Europe.

Bookimed Expert Insight: While many clinics offer vitrification, those with Joint Commission International (JCI) accreditation, like Sikarin Hospital, follow more rigorous audited protocols for sample tracking. Data shows that Thailand is a top 5 global destination for fertility, largely due to these high-standard labs that match Western success metrics at lower technical costs.

Patient Consensus: Patients emphasize the importance of requesting written thaw survival statistics and confirming the use of IATA-approved tanks if planning future international embryo transport.

Success rates for frozen embryo transfers in Thailand typically range from 50% to 70% per transfer at leading fertility centers. These high outcomes result from advanced vitrification technology and preimplantation genetic testing for aneuploidy (PGT-A), which aligns with global standards for reproductive medicine.

• Success markers: Euploid embryos combined with optimal uterine lining yield success rates above 60%.
• Age factors: Patients under 38 often achieve 60–65% live birth rates using screened embryos.
• Technological impact: Sequential estrogen priming can boost pregnancy rates by 10–15% over natural cycles.
• Transfer protocol: Many clinics perform frozen transfers exclusively to minimize ovarian hyperstimulation syndrome (OHSS) risks.

Bookimed Expert Insight: Thailand has become a global hub for frozen embryo transfers because clinics like Sikarin Hospital maintain JCI accreditation while offering significant savings. While US frozen cycles average $15,300, specialized centers in Bangkok provide cryopreservation for $3,000 to $5,000. This price gap allows patients to invest more in PGT-A screening, which is the single most important factor for increasing success rates in older patients.

Patient Consensus: Patients report that while clinic reputation is vital, success often depends on uterine lining preparation. Many emphasize that focusing on lining thickness and using genetic screening provides the most reliable path to a positive pregnancy test.

Legally, only married heterosexual couples can freeze embryos in Thailand. Current Medical Council of Thailand regulations on assisted reproductive technology (ART) require a valid marriage certificate. Single individuals, same-sex couples, and unmarried partners are generally prohibited from accessing embryo cryopreservation services within Thai clinics.

• Legal status: Patients must provide official marriage documentation to access ART services.
• Union type: Regulations specifically restrict embryo freezing to heterosexual married couples only.
• Specialist oversight: Procedures are managed by registered assisted reproductive technology specialists in Bangkok.
• Clinic compliance: Facilities like Prime Fertility Clinic strictly enforce these legal marriage requirements.

Bookimed Expert Insight: While many choose Bangkok for its high tech, the legal landscape is exceptionally rigid compared to Europe. Our data shows that top clinics like Sikarin Hospital maintain JCI accreditation, but this clinical quality does not bypass national marriage laws. Patients often overlook that storage extensions require ongoing proof of a valid legal marriage. If your marital status changes, the clinic may be legally required to terminate storage after the standard 2 to 5 year period.

Patient Consensus: Patients report that clinics verify marriage certificates multiple times during the process. Many suggest ensuring all legal paperwork is notarized before arrival to avoid service refusal.

Importing embryos into Thailand is permitted with proper documentation, while exporting them is subject to stricter regulations. Current legal frameworks like the Protection of Children Born Through Assisted Reproductive Technologies Act require explicit permits from the Thai Ministry of Public Health and specialized medical couriers for transport.

• Import requirements: Patients must provide a Certificate of Origin and obtain a Thai FDA permit.
• Export process: Exporting requires clinic coordination and typically a 4 to 6 week lead time.
• Transport protocol: Regulations mandate use of certified dry shipper couriers rather than hand-carrying genetic material.
• Facility standards: Most procedures occur in Joint Commission International (JCI) accredited centers like Sikarin Hospital.

Bookimed Expert Insight: While general legal summaries suggest a total ban, our data shows clinics like Prime Fertility Clinic actively assist international patients with the logistical paperwork for imports. Curiously, while importing is straightforward with a Certificate of Origin, exporting is the real bottleneck; it requires navigating multiple government layers that most general descriptions overlook.

Patient Consensus: Patients report that while shipping embryos into Bangkok is manageable via specialized couriers, you must ensure your home country’s import rules align with Thailand’s export permits to avoid transit delays.

Single women and same-sex couples cannot legally undergo embryo cryopreservation in Thailand due to the 2015 Assisted Reproductive Technologies Act. This law restricts embryo creation and storage to legally married heterosexual couples. Applicants must typically present a certified marriage certificate before clinics proceed with fertilization or freezing.

• Marriage requirement: Thai law explicitly requires a legal marriage certificate for embryo-related procedures.
• Single women: Creating embryos is prohibited, but egg freezing is widely available for individuals.
• Same-sex couples: Access is currently restricted despite recent shifts in Thai marriage equality laws.
• Legal alternatives: Patients often freeze eggs in Bangkok then transfer them to other jurisdictions.

Bookimed Expert Insight: While embryo freezing remains restricted, Thailand has become a global hub for oocyte cryopreservation. Clinics like Sikarin Hospital or Prime Fertility Clinic maintain Joint Commission International (JCI) standards for egg quality. This allows single women to preserve fertility now and move materials to more flexible regions later if needed.

Patient Consensus: Many patients report that clinics strictly verify marital status before any IVF steps. Most recommend freezing eggs as a legal preliminary step while monitoring the evolving legislative landscape in Bangkok.

In Thailand, fertility specialists typically transfer 1 high-quality embryo to minimize the risk of multiple births. This single embryo transfer approach is the standard recommendation for women under 38. For older patients or those with lower-grade embryos, 2 embryos may be considered to balance success rates.

• Transfer standard: Single embryo transfer is routinely recommended for women under 35-38.
• Risk mitigation: Selective transfer strategies significantly cut the risks associated with twin pregnancies.
• Patient age: Clinics may offer 2-embryo transfers for patients aged 38 or older.
• Success rates: Thai clinics report 40-60% success rates per frozen single embryo transfer.

Bookimed Expert Insight: While single transfer is the goal, some top-tier Bangkok clinics utilize advanced preimplantation genetic testing to ensure only the healthiest embryo is selected. This allows surgeons like those at Prime Fertility Clinic to maintain high success rates without the complications of multiple births. It is a smarter choice than transferring several untested embryos.

Patient Consensus: Patients report that single embryo transfer is increasingly standard in Thai clinics to ensure safer pregnancies. Many appreciate the focus on high-quality frozen embryos rather than higher quantity.

A standard embryo cryopreservation cycle in Thailand requires a stay of 12 to 16 days. This timeframe covers ovarian stimulation, regular ultrasound monitoring, and the egg retrieval procedure. Most patients are cleared to fly home 48 hours after retrieval while labs finish the fertilization and freezing process.

• Stimulation phase: Requires 8 to 12 days of daily injections and clinic monitoring visits.
• Egg retrieval: Completed on day 13 to 15 as a brief outpatient surgical procedure.
• Recovery period: Patients typically rest for 2 to 3 days before departing Thailand.
• Future transfers: Returning for a frozen embryo transfer requires a shorter 3 to 7-day stay.

Bookimed Expert Insight: While many clinics suggest a 20-day window, our data shows patients often optimize their stay to 14 days by starting initial screenings remotely. Leading specialists like those at Prime Fertility Clinic or JCI-accredited Sikarin Hospital provide digital coordination to ensure you arrive exactly when stimulation begins, saving nearly a week of hotel costs.

Patient Consensus: Patients emphasize adding a 2-day buffer for the trigger shot timing, as retrieval dates can shift based on follicle growth. Most feel comfortable flying shortly after retrieval since clinics provide digital updates on embryo grading once they have returned home.
