If you are wondering what is a blastocyst, it is an embryo that has reached the stage of the blastocyst — an empty structure with an inner cell mass and outer layer of cells. At Day 5 of development in the incubator, the blastocyst embryo is larger and contains more cells than a Day 3 embryo. Understanding blastocyst vs embryo helps couples see why this stage can increase implantation opportunities during blastocyst IVF.
These are then graded and either transferred in case of a fresh transfer or frozen in case of a frozen transfer
No more than two blastocysts can be implanted at a single transfer and the excess are always stored for future use
If we want to reduce the chance of multiple pregnancy to a minimum,it is preferable to opt for an elective single embryo transfer referred to as e-SET
The process is carried out in a specially equipped IVF laboratory:
In conventional IVF, embryos are transferred on Day 3, whereas blastocyst IVF transfers occur on Day 5 at the blastocyst stage. Longer culture allows embryologists to select embryos with the best implantation potential, increasing pregnancy rates and reducing multiple pregnancies.
Kanaa Fertility Center has a high success rate for blastocyst IVF cycles. Our expert team guides you through each step — from consultation, extended embryo culture, and blastocyst embryo transfer, to follow-up. With priority on patient care, education, and safe procedures like e-SET, we ensure your well-being throughout your fertility journey.
A blastocyst is an embryo that has developed for about 5 days after fertilization. It has more cells and a fluid cavity, making it more likely to implant successfully.
Blastocyst culture is the process of growing embryos in a lab until they reach the blastocyst stage (Day 5) before transfer or freezing.
In blastocyst IVF, embryos are transferred at the blastocyst stage, which can increase implantation chances and reduce the risk of multiple pregnancies.
An embryo is the early stage after fertilization (Day 2–3), while a blastocyst embryo is a more developed stage (Day 5) with a higher chance of implantation.
Typically, no more than two blastocyst embryos are transferred at one time. For reducing multiple pregnancy risks, elective single embryo transfer (e-SET) is recommended.
Yes. Good-quality blastocyst embryos can be frozen for future use, making future IVF cycles less invasive.
Yes. It is a widely used and safe technique performed under strict laboratory conditions by skilled embryologists.
Blastocysts are evaluated based on size, cell number, and inner cell mass quality to select the best embryos for transfer or freezing.
Yes. Transferring embryos at the blastocyst stage generally improves implantation rates compared to earlier-stage embryos.
Not all embryos develop into blastocysts. Some may arrest before Day 5, which is why careful lab monitoring during blastocyst culture is important.
