Embryo freezing (vitrification) has transformed IVF strategy. Instead of transferring fresh embryos immediately, most modern protocols freeze all embryos after biopsy for PGT-A, then transfer a single euploid embryo in a subsequent frozen embryo transfer (FET) cycle. This "freeze-all" approach produces equal or better outcomes than fresh transfers and gives you time for genetic testing and optimal uterine preparation.
Cost Comparison
| Component | US Cost | Colombia Cost |
|---|---|---|
| Embryo vitrification (freezing) | $1,000–$2,000 | $500–$1,000 |
| Annual embryo storage | $500–$1,000/year | $200–$400/year |
| Frozen embryo transfer (FET) cycle | $3,000–$5,000 | $1,000–$2,500 |
| FET medications (estrogen + progesterone) | $500–$1,500 | $100–$400 |
| PGT-A testing (before freezing) | $3,000–$6,000 | $1,000–$2,500 |
The Freeze-All Strategy
Modern IVF increasingly uses a freeze-all protocol for good reason:
- PGT-A compatibility: Biopsy results take 1–2 weeks. Freezing buys time for genetic testing without rushing a transfer.
- Uterine environment: Ovarian stimulation creates supraphysiologic hormone levels that may impair endometrial receptivity. Transferring in a subsequent, hormonally controlled cycle may improve implantation.
- Medical tourism logistics: Freeze-all allows you to complete your stimulation and retrieval in one trip (7–10 days), wait for PGT-A results at home, then return for a shorter FET trip (5–7 days).
- Banking across cycles: For patients over 38, banking embryos across 2–3 retrieval cycles, testing the entire batch, and then transferring the best euploid embryo maximizes success per transfer.
Store Abroad or Ship Home?
If you freeze embryos in Colombia, you have two options for future use:
Option A: Store in Colombia, return for FET
- Storage cost: $200–$400/year in Colombia vs. $500–$1,000/year in the US
- FET cost: $1,000–$2,500 in Colombia vs. $3,000–$5,000 in the US
- Trip length: 5–7 days for FET
- Advantage: Lower ongoing costs, same clinical team handles retrieval and transfer
Option B: Ship embryos to a US clinic
- Shipping cost: $1,000–$3,000 via specialized cryoshipping services (e.g., Cryoport, ARKCryo)
- Logistics: Embryos travel in liquid nitrogen dry shippers. FDA import documentation required. Your US clinic must agree to accept shipment.
- Advantage: FET at a local clinic. Convenient for monitoring and early pregnancy care.
- Drawback: Shipping adds cost and complexity. Not all US clinics accept internationally shipped embryos.
FET Trip Planning
A frozen embryo transfer trip is simpler and shorter than a retrieval trip:
- Pre-trip (at home): Start estrogen (oral or patches) per your Colombian RE's protocol. Monitor lining thickness via ultrasound at your local clinic.
- Day 1–2: Arrive in Colombia. In-person ultrasound to confirm lining readiness (typically >7mm, trilaminar pattern). Start progesterone supplementation.
- Day 3–5: Embryo transfer (a painless 5–10 minute procedure under ultrasound guidance). Rest for 24–48 hours.
- Day 5–7: Fly home. Continue progesterone supplementation as directed.
- Day 14 post-transfer (at home): Beta HCG blood test at a local lab.
