Fresh Embryo vs Frozen Embryo: Which Choice is Best for Your IVF Journey?

If you're looking into IVF, one of the key decisions you'll face is whether to use fresh or frozen embryos for transfer. This choice can seem overwhelming, especially when trying to understand the differences between fresh and frozen cycles and which option may give you the best chance of success. Each approach has its benefits and potential drawbacks, and the right choice largely depends on your unique health factors, fertility goals, and treatment preferences.

 

In this blog, we will explain the main differences between fresh embryo and frozen embryo transfer, and tell you about the benefits and challenges of each option in simple terms. You will learn how these two types of IVF cycles – fresh cycles vs. frozen cycles – work, what situations they are best suited for, and the success rates associated with each.

 

Whether you are considering a fresh embryo transfer or considering the benefits of frozen embryos, this blog will provide you with the information you need to confidently pursue your IVF journey.

What are Fresh and Frozen Embryos?

Embryo transfer is a crucial step in the IVF process, and it involves transferring the embryos to the uterus for potential implantation. The difference between fresh and frozen embryos mainly lies in how they are handled after fertilisation:

 

        1.   Fresh Embryos: These embryos are created during the same IVF cycle in which the eggs are extracted and fertilized. They are usually transferred to the uterus within a few days without freezing.

        2.   Frozen Embryos: After fertilization, these embryos are cryopreserved, or frozen, for use in future cycles. This method can give the body time to recover between the egg retrieval and embryo transfer stages.

 

In many cases, frozen embryo transfer (FET) is increasingly being preferred due to its flexibility and likelihood of success. However, the best option depends on individual factors such as age, health, and personal preferences. Let's dive into the details of each option and evaluate the benefits and limitations.

Fresh Cycle vs Frozen Cycle: Understanding the Difference

Both fresh and frozen embryo transfers fall under different types of IVF cycles:

 

        •   Fresh Cycle: In a new IVF cycle, eggs are retrieved, fertilized, and then transferred within the same cycle, often within 3–5 days.

        •   Frozen Cycle: A frozen cycle involves transferring previously frozen embryos from an earlier cycle into the uterus after thawing them. This allows for more flexibility, as you can choose the time of embryo transfer based on your physical readiness.

 

Now that we understand these procedures, let’s compare their pros and cons to see which one is best suited for your fertility journey.

Pros and Cons of Fresh Embryo Transfer

Pros of Fresh Embryo Transfer

        •   Immediate Use of Embryos: Fresh embryo transfer allows embryos to be transferred as soon as they are ready, reducing the time from fertilization to transfer.

        •   Less Waiting Time: If both the egg and sperm are ready for fertilization, a fresh cycle may have a shorter delay than a paused cycle.

        •   Potential for Natural Preparation: Some patients prefer fresh embryo transfer if they feel it more closely mimics natural conception, although this depends on individual health.

Cons of Fresh Embryo Transfer

        1.   Hormonal Impact: A new cycle often requires more hormonal medications, which can take a toll on the body and increase stress levels.

        2.   Limited Flexibility: Since the embryos are not frozen, the timing of the embryo transfer is less flexible. If your body is not fully ready, the cycle may not be as successful.

        3.   Lower Success Rates in Some Cases: Research has shown that for some groups, particularly those with high ovarian stimulation, success rates may be lower than with frozen embryos.

Pros and Cons of Frozen Embryo Transfer (FET)

Pros of Frozen Embryo Transfer

        1.   Higher Success Rates in Many Cases: Studies have shown that frozen embryo transfer can lead to higher implantation rates, especially for patients with a high ovarian response. This is because the body gets more time to recover from the stimulation phase.

        2.   Less Hormonal Stress: With a frozen cycle, the body can return to a natural state without the immediate hormonal effects of fresh embryo transfer. This can provide a more comfortable environment for embryo implantation.

        3.   Flexible Timing: Frozen embryos give patients more control over timing, allowing them to wait until they feel physically and mentally ready for the transfer.

        4.   Reduced Risk of OHSS (Ovarian Hyperstimulation Syndrome): For women at risk for OHSS, frozen embryo transfer may reduce this risk, as it gives the ovaries a chance to stabilize after stimulation.

Cons of Frozen Embryo Transfer

        1.   Freezing and Thawing Process: Although the success rate is high, there is a slight chance that the embryos may not survive the freezing and thawing process.

        2.   Longer Process Overall: Frozen embryo transfers often involve more steps and may require additional time, which may feel like a longer journey for some couples.

        3.   Additional Costs: In some cases, frozen cycles may incur additional costs for freezing and storing embryos, depending on the clinic and country.

Is Frozen Embryo Better Than Fresh? Evaluating Success Rates and Health Factors

When comparing fresh vs frozen embryo transfer, several studies now show a slight advantage with frozen embryos, especially in specific patient groups:

 

        •   Patients with High Ovarian Response: Patients who experience a high response to ovarian stimulation typically see better outcomes with frozen embryos.

        •   Reduced Risk of Miscarriage: Some studies have shown that frozen embryos may reduce the risk of early miscarriage, which is an added benefit.

        •   Favourable for Endometrial Health: With frozen embryo transfer, the endometrium may be in a better condition to support implantation.

 

While frozen embryo transfers are generally associated with positive outcomes, it is important to remember that individual factors play a large role. For some patients, fresh embryos may still be the best option, depending on age, health status, and personal preferences.

Common Questions about Fresh vs Frozen Embryo Transfers

Which Has a Higher Success Rate?

Overall, recent studies suggest that frozen embryo transfer may offer slightly higher success rates, especially in women with high ovarian response. However, the best option varies, and individual success rates depend on many factors, including age, reproductive health, and embryo quality.

How Do I Decide Which Is Right for Me?

You should discuss with your fertility specialist to decide between fresh and frozen embryo transfer. Your doctor will consider your age, ovarian response, medical history, and personal preferences to guide you in making the right choice.

Can I Choose to Freeze My Embryos for Later?

Yes, many patients choose to freeze embryos for later use, even if they initially try a new cycle. This allows them to attempt additional transfers without having to go through another retrieval cycle.
