Frozen embryo transfer (FET) is a routine, evidence-based step in modern fertility care, and it is offered abroad by MTA-verified clinics such as IVF Life Alicante, InSer Fertility Institute, and Azul Fertility Experts, though success still depends on embryo quality, the age at which the eggs or embryos were created, and uterine factors, so no clinic can promise a positive result. If you want to compare accredited options, you can browse verified providers here.
This guide explains what an FET involves, why patients choose to have one abroad, the main preparation protocols, the step-by-step experience, honest success-rate framing, typical costs, and the logistics of shipping embryos across borders.
Understanding Frozen Embryo Transfer
A frozen embryo transfer is the process of thawing a previously frozen embryo and placing it into the uterus. The embryo was created during an earlier cycle, then stored using vitrification, a fast-freezing technique that is now standard and protects embryos very well. FET is well established and performed routinely at fertility clinics worldwide, so it is ordinary, proven care rather than anything experimental.
Embryos used in an FET can come from several sources: surplus embryos from a prior in vitro fertilization (IVF) cycle that were frozen for later use, an egg or embryo donation cycle, or a planned freeze-all cycle, in which all embryos are frozen rather than transferred fresh, sometimes to allow preimplantation genetic testing for aneuploidy (PGT-A). Because the demanding parts of IVF, the ovarian stimulation and egg retrieval, have already happened, an FET is shorter and simpler, with the focus on preparing the uterine lining and timing the transfer precisely.
Why Patients Consider Frozen Embryo Transfer Abroad
Many patients travel for an FET because their embryos are already stored abroad, so returning to the clinic that created them is the most direct path. Coordinating with a donor program abroad is another common reason, since some destinations have well-developed egg and embryo donation systems.
Cost is a frequent factor, since in some countries an FET can be considerably more affordable than at home, which matters when several attempts are needed. English-language coordination and dedicated international patient teams make the logistics manageable from a distance. Some patients also ship frozen embryos internationally to a clinic abroad.
Be realistic, though: choosing a clinic abroad does not change what determines success, and lower cost does not mean higher chances. Laws and logistics around embryo storage, consent, and cross-border movement vary by country and can change, so confirm the current requirements directly with the clinic. Treat that as practical information to verify, not legal advice.
The Two Main Protocols and Endometrial Preparation
Before a transfer, the uterine lining, or endometrium, must be prepared so it is receptive to the embryo. There are two main approaches. In a natural-cycle FET, the clinic tracks your own menstrual cycle and times the transfer to your natural ovulation, using little or no medication, which suits regular cycles. In a medicated or hormone-prepared FET, estrogen and later progesterone build and mature the lining on a controlled schedule, which makes timing more flexible when traveling.
Whichever protocol is chosen, the clinic monitors your lining with ultrasound, and sometimes blood tests, to confirm it has reached a suitable thickness before scheduling the transfer.
Step by Step: What to Expect
An FET follows a clear sequence. First comes a consultation, often by video, where the team reviews your history and prior cycles, then agrees on a protocol. Next is lining preparation and monitoring, either following your natural cycle or using prescribed hormones. On the transfer day, the laboratory thaws the chosen embryo and confirms it has survived, which vitrified embryos usually do at high rates.
The transfer itself typically takes only a few minutes. Using a thin, soft catheter guided by ultrasound, the clinician places the embryo into the uterus. No anesthesia is needed, most people feel little more than during a routine cervical exam, and you can usually resume normal activity the same day.
Then comes the two-week wait, the interval before a pregnancy test can reliably detect the result. During this time you continue any prescribed progesterone or other support, and at the end a blood test measuring hCG confirms whether the transfer led to pregnancy. It is a hopeful but uncertain stretch, and good clinics stay in contact through it.
Success Rates: An Honest View
Frozen embryo transfer outcomes are often comparable to fresh transfers, and with good-quality embryos they can be favorable, partly because the body is not recovering from stimulation. That is encouraging, but it is not a guarantee. Success depends most on embryo quality and the age at which the eggs or embryos were created, since embryos made from younger eggs tend to have better potential. Uterine factors matter too.
Be cautious of any clinic that promises a certain result or quotes a headline success rate without context. Reported figures depend heavily on patient age, embryo grade, and PGT-A use. Ask what a rate refers to and how it applies to your situation, since honest, individualized expectations are a sign of a trustworthy program.
What Frozen Embryo Transfer Costs Abroad
An FET is usually much cheaper than a full fresh IVF cycle, because it does not involve ovarian stimulation medications or egg retrieval. Abroad, prices are commonly in the low single-digit thousands of US dollars, though this varies by country and clinic. Fertility care is generally self-funded and not covered by insurance.
Insist on an itemized written quote. It should spell out the consultation, monitoring scans and blood tests, lining-preparation medications, the embryo thaw, the transfer, laboratory fees, and the pregnancy test. If any embryos remain, ask about ongoing annual storage fees, and where relevant ask separately about shipping embryos, which is billed by specialist couriers.
Shipping Frozen Embryos Across Borders
If your embryos are stored in one country and you want your transfer in another, they can often be shipped by a specialist cryo-shipping company using validated liquid-nitrogen containers that keep them safely frozen. It is a well-practiced service, but it involves paperwork: you will typically need consent forms and records from both the releasing and receiving clinics. Rules on consent, storage limits, and cross-border movement differ by country and can change, so confirm current requirements with both clinics before you travel. This is information to verify, not legal advice.

Comparing These Providers
All three clinics offer frozen embryo transfer and coordinate care for international patients, so the right choice often comes down to geography, language comfort, and where your embryos are stored or your donor program is based. A clinic in Spain may suit patients within Europe, while the Colombian and Costa Rican programs can appeal to those in the Americas.
Beyond location, weigh how clearly each clinic communicates, how it explains your chances, and how well it supports the practical details, including any embryo shipping.
Planning Your Frozen Embryo Transfer Trip Abroad
An FET is well suited to a short trip, but it needs careful timing around your lining preparation and transfer window.
- Involve your own treating physician or fertility specialist before you travel, and share the plan with them.
- Bring your full records, including embryo details, prior cycle notes, and any PGT-A results.
- Continue any established, prescribed care and medications, and confirm your lining-preparation protocol before departure.
- Hold realistic expectations, since even with good embryos success is not guaranteed and more than one transfer is sometimes needed.
- Plan for follow-up, including the two-week wait, the pregnancy test, and remote support afterward.
How to Choose the Right Frozen Embryo Transfer Provider
A good provider combines clinical quality with honest communication and reliable coordination.
- Confirm the clinic and its laboratory are accredited and experienced with vitrification and frozen embryo transfer.
- Ask for individualized success expectations based on your embryo quality and the age at which the eggs or embryos were created, and be wary of guarantees.
- Request a fully itemized written quote covering monitoring, medications, thaw, transfer, and storage, plus any shipping.
- If your embryos are stored elsewhere, check the clinic's process for cross-border shipping, consent, and records.
- Assess how responsive and clear the international team is, and when you are ready to compare options side by side, get a free quote through Better by MTA.
