Blastocyst Transfer
Advancing IVF Success with Precision, Care, and Science
At Almond Blossoms Fertility & Well-being Center in Dubai, we use the most advanced reproductive technologies to support couples on their fertility journey.
One of the most effective developments in modern IVF is the blastocyst transfer — a refined technique that allows our embryologists to select embryos that show good development.
This approach not only supports implantation timing but also helps ensure safer, more natural pregnancies with fewer complications.
What Is a Blastocyst?
A blastocyst is an embryo that has developed for five to six days after fertilization.
At this stage, the embryo contains around 100–200 cells and has begun to form two distinct parts:
- The inner cell mass, which will become the baby.
- The trophectoderm layer, which will form the placenta.
This advanced stage of development allows our embryologists to observe which embryos are growing normally making selection for transfer far more accurate.
What Is Blastocyst Transfer?
Blastocyst transfer is the process of transferring one or more embryos at the blastocyst stage into the uterus during an IVF cycle.
Compared to earlier-stage transfers (usually done on day 2 or 3), blastocyst transfer gives the embryo more time to develop under controlled laboratory conditions. This helps ensure that only the most viable embryos are chosen for transfer, closely mimicking the natural timing of embryo implantation in the womb.
Advantages of Blastocyst Transfer
Supports Pregnancy Planning
Because only embryos that have effectively reached the blastocyst stage are transferred.
Aims to Reduce Multiple Embryo Transfers
Fewer embryos are needed for transfer, reducing the need for twins or triplets.
Better Synchronization
The uterine lining is at its aligned with natural implantation timing.
Improved Embryo Selection
Embryologists can assess growth, cell quality, and morphology more accurately before transfer.
Supports Genetic Testing
Blastocyst-stage embryos are suitable for Preimplantation Genetic Testing (PGT-A) to identify chromosomally normal embryos.
Who Can Benefit from Blastocyst Transfer?
Blastocyst transfer is ideal for many couples, especially those who:
Have multiple good-quality embryos available after fertilization.
Have cared failed IVF cycles with earlier transfers.
Are undergoing PGT-A (genetic testing) or family balancing.
Wish to reduce the number of embryos transferred without compromising success rates.
Prefer a more natural implantation environment.
The Blastocyst Transfer Process at Almond Blossoms
After egg retrieval, fertilization is achieved either naturally (IVF) or through ICSI (Intracytoplasmic Sperm Injection). Embryos are then cultured in our advanced laboratory using time-lapse monitoring and carefully controlled conditions.
Our embryologists observe each embryo’s growth daily. Only those developing at a healthy pace are nurtured to the blastocyst stage.
On day five, the strongest blastocysts are selected for transfer based on morphology and development rate. If PGT-A testing is required, a few cells are gently biopsied for chromosomal screening.
A single (or occasionally double) blastocyst is transferred into the uterus using a fine catheter a painless, quick, and anesthesia-free procedure.
High-quality embryos not transferred are vitrified (frozen) for future use, ensuring the future treatment planning.
After the Transfer
After blastocyst transfer, our team continues to support patients through the two-week waiting period with careful follow-up, emotional support, and medication guidance to aid implantation and early pregnancy.
