Blastocyst Transfer

Blastocyst transfer represents the final stage of an IVF cycle, in which embryos are allowed to develop in the laboratory until the blastocyst stage before being transferred into the uterus. This advanced developmental stage enables a more accurate selection of embryos with high potential, contributing to increased chances of achieving an ongoing pregnancy.

What is Blastocyst Transfer?

Blastocyst transfer is a procedure performed within IVF treatments, where embryos are cultured in the laboratory until day five or six of development. At this stage, the embryos have already formed a complex structure, allowing for a more precise evaluation of their reproductive potential.

This method is recommended when an advanced selection of embryos is desired, as only those that develop appropriately reach the blastocyst stage. Transferring at this point can increase implantation rates because the embryo is at a stage similar to the one it would naturally reach upon entering the uterus.

Depending on the specifics of each case, blastocyst transfer may be integrated with genetic analysis of embryos (PGT), cryopreservation of additional blastocysts, or strategic planning of IVF cycles to optimise outcomes.

Treatment steps

Your step-by-step guide to Blastocyst Transfer

Every treatment is built on a well-defined medical process, carefully structured and tailored to the individual needs of each case. The objective is for the patient to receive clear information, continuous support, and the assurance that every stage is explained in detail—from the initial consultation to the subsequent monitoring period. The entire journey is guided with professionalism, ensuring that medical decisions are made with full understanding.

Although procedures vary depending on each patient’s diagnosis, treatment always begins with a thorough evaluation of the individual situation and the establishment of a personalized strategy. This approach increases the real chances of success and ensures continuity of care throughout the entire journey toward becoming a parent.

Blastocyst Transfer
During your initial consultation, we will review your medical history and your response to previous treatments to determine whether blastocyst transfer is the most appropriate option for your situation. We will discuss the next steps together and provide all the information you need to make a safe and informed decision.
You will follow a personalized stimulation protocol, followed by egg retrieval and laboratory fertilization. Our team will monitor you closely and adapt the treatment according to your biological rhythm.
Fertilized embryos are cultured in the laboratory and monitored daily. Over five to six days, we track the development of each embryo to identify those reaching the optimal blastocyst stage.
A high-quality blastocyst is selected for uterine transfer, using a delicate and precise procedure performed under ultrasound guidance. If several good-quality blastocysts develop, they may be cryopreserved for future use.
Approximately two weeks after the transfer, you will have a blood test to confirm whether implantation occurred successfully and pregnancy has begun.

F.A.Q.

Blastocyst Transfer F.A.Q.

Starting a treatment or medical procedure often raises questions regarding safety, effectiveness, and its impact on fertility. This section provides general explanations to help patients better understand the working steps, what the procedure involves, and what results to expect. The information is presented in an accessible manner to facilitate a clearer understanding of the medical process.

If additional questions arise or if the individual situation requires specific clarifications, a direct discussion with the physician can offer personalized guidance and recommendations tailored to each case. Proper guidance supports informed decision-making and ensures that treatment proceeds safely.

Day 3 embryos are transferred earlier in development, while blastocysts (Day 5 or 6) have had more time to grow, allowing for better embryo selection.
Yes. Studies show that transferring a blastocyst often results in higher implantation and pregnancy rates, especially when embryo quality is high.
Not all embryos will reach the blastocyst stage. That is why this method is typically used when multiple good-quality embryos are available.
The transfer itself is the same. The main difference is that the embryo is transferred later, at a more advanced stage.
Yes. If multiple blastocysts are formed, the surplus can be cryopreserved and used in future frozen embryo transfer (FET) cycles.
No. The procedure is safe and commonly used. Your doctor will recommend it only if it offers a clear benefit for your situation.
