FET vs fresh transfer is a common question for couples who are going through fertility treatments. Both these methods are popular in IVF, but they differ in when the embryo is transferred. In FET, the embryos are frozen, thawed and then transferred at a later time. However, in a fresh transfer, the embryos are placed in the uterus just a few days after fertilization. Both methods have their own benefits but the right choice totally depends on the individual’s health.
At RISAA IVF, Dr. Rita Bakshi, a senior IVF specialist helps patients to decide whether FET or fresh transfer is best for them. In this blog, we are going to discuss the main differences and benefits of both options. We will also tell you what you should keep in mind when choosing between Frozen Embryo Transfer and Fresh Embryo Transfer.
What is Frozen Embryo Transfer (FET)?
Frozen Embryo Transfer (FET) is a medical procedure which is used in IVF (In Vitro Fertilisation). In this procedure, embryos that were previously frozen are thawed and transferred into the woman’s uterus. FET procedure helps doctors to prepare the woman’s body for implantation at a later stage.
Additionally, in the FET timeline, embryos can be frozen at various stages. For example, it can be frozen at blastocyst or early embryo stages, and stored until the right time for transfer. FET offers flexibility to couples and it also avoids transferring embryos in the same cycle as egg retrieval. This helps to offer a more controlled environment and timing that suits the patient’s health.
What is Fresh Embryo Transfer?
Fresh Embryo Transfer is a procedure in IVF where embryos are placed into the woman’s uterus. This is done just a few days after the eggs are retrieved and fertilized. There is no freezing involved in this method. The transfer usually happens within 3 to 5 days after fertilization, during the same IVF cycle.
Between FET vs Fresh Transfer, Fresh transfer is often recommended by doctors. It’s best when the woman’s body responds well to ovarian stimulation and the uterine lining is ready to accept the embryo. It gives faster results because the process is done without any delay between fertilization and embryo transfer.
FET vs Fresh Transfer: Key Differences
FET vs Fresh Transfer mainly differ in the timing and preparation in the IVF process. In FET, embryos are frozen and transferred in a later cycle and gives the body some time to recover after egg retrieval. In a fresh transfer, embryos are placed in the uterus just a few days after fertilization, during the same cycle. Both methods have their own advantages. Let’s do a quick comparison of FET vs Fresh Transfer through a simple table.
Feature | Frozen Embryo Transfer (FET) | Fresh Embryo Transfer |
Timing | Embryos are frozen and transferred later | Embryos are transferred immediately |
Preparation | Happens in a separate, controlled cycle | Happens in the same cycle as egg retrieval |
Body Recovery | Body gets time to heal before transfer | Transfer happens right after stimulation |
Success Rates (in some cases) | May be slightly higher | Depends on the body’s condition |
Flexibility | More flexible scheduling | Less flexible, depends on same cycle |
Suitability | Good for women with high hormone levels | Good when the body is ready immediately |
Benefits of Frozen Embryo Transfer
Frozen Embryo Transfer (FET) has become very popular among couples due to its flexibility and advantages. It offers better timing and can sometimes lead to higher success rates in comparison with fresh transfers. Let’s see the benefits of FET:
- It gives the body time to heal after egg retrieval.
- FET offers better control over the timing of transfer.
- It reduces the chances of ovarian hyperstimulation syndrome (OHSS).
- It may lead to higher implantation and pregnancy rates in some cases.
- FET gives the chance to preserve extra embryos for future use.
- It can be a safer option for women with certain medical conditions.
Benefits of Fresh Embryo Transfer
Fresh Embryo Transfer is often the first choice for many IVF cycles. This is because it follows the natural flow of the treatment without extra steps like freezing and thawing. It can offer quick results because the embryo is transferred immediately after fertilization. Let’s see the benefits of fresh embryo transfer:
- No need to wait for a separate transfer cycle.
- Faster process from egg retrieval to embryo transfer.
- It avoids potential risks that are linked to freezing and thawing.
- It can be a good option if the uterine lining is already ideal.
- Fresh Transfer is often preferred when hormone levels are balanced and stable.
- It also reduces emotional stress by completing the cycle sooner.
Factors to Consider When Choosing Between FET vs Fresh Transfer
There are many factors to consider if you’re choosing between FET vs Fresh Transfer. Every couple’s situation is different, and the decision should be made after a careful discussion with a fertility specialist. Let’s look at the key factors to consider:
- The woman’s hormone levels during the stimulation cycle.
- Quality and number of embryos available.
- Condition of the uterine lining at the time of transfer.
- Risk of developing ovarian hyperstimulation syndrome (OHSS).
- Previous IVF history or past implantation failures.
- Overall health and any underlying medical conditions.
- Emotional readiness and timing preferences for the transfer.
- Recommendations from the IVF specialist based on individual needs.
How FET and Fresh Transfer Affect IVF Success Rates?
The success rates of FET vs Fresh Transfer can vary based on several factors. In some cases, frozen embryo success rate has shown slightly higher because the body is more relaxed and hormonally balanced compared to a fresh cycle.
Fresh transfers, on the other hand, can also be very successful. Especially if the body responds well to treatment and the uterus is ready for implantation. It’s important to remember that the best option is different for every couple. So, it’s better to consult a fertility specialist and follow their advice carefully.

Frequently Asked Questions (FAQs):
- Is it better to transfer embryos frozen or fresh?
It depends on the individual case; some women have higher success rates with frozen embryos, while others do well with fresh transfers.
- What is the difference between FET and fresh transfer?
In FET, embryos are frozen and transferred later; in a fresh transfer, embryos are placed in the uterus a few days after fertilization.
- Do fresh embryos implant faster?
Fresh embryos are transferred immediately, but implantation speed depends more on the body’s condition rather than the type of transfer.
- Is it better to implant 2 embryos?
Transferring 2 embryos can increase pregnancy chances but it can also raise the risk of twins or multiple pregnancies.
- What is the age limit for frozen embryo transfer?
There is no strict age limit, but many clinics recommend FET before the woman turns 50 for better success and safety.
- What is the best embryo grade?
Top-quality embryos, like Grade A or a high-grade blastocyst, are considered best for higher chances of implantation.
- Are babies born from frozen embryos healthy?
Yes, studies show that babies who are born from frozen embryos are just as healthy as those born from fresh embryo transfers.
