Blastocyst Culture

About This Treatment

Blastocyst culture extends embryo development in the laboratory to day 5 or day 6, allowing embryologists to identify the embryos with the highest implantation potential. By growing embryos to this advanced stage, we can transfer fewer embryos while maintaining excellent pregnancy rates, and select the best candidates for genetic testing or cryopreservation.

Treatment Process

1. 1

   Fertilization

   Eggs and sperm are combined in the laboratory through IVF or ICSI to create embryos for culture.

2. 2

   Early Embryo Culture

   Embryos are monitored in a controlled incubator environment during the first few days of development.

3. 3

   Extended Culture to Day 5–6

   Embryos continue developing to the blastocyst stage, allowing natural selection of the most viable candidates.

4. 4

   Embryo Assessment

   Embryologists grade blastocyst quality based on expansion, inner cell mass, and trophectoderm appearance.

5. 5

   Transfer or Cryopreservation

   The best-quality blastocyst is selected for fresh transfer or vitrified for a future frozen embryo transfer cycle.
