Blastocyst Culture and Transfer
Is a technique in which an embryo is developed in the laboratory for 4-6 days after
fertilisation before being placed in womb. The embryo gains many cells as a result
of being developed for so many days. The embryos developed for 4-6 days are much
more advanced than the ones developed for just three days. These Embryos are called
blastocysts.
The embryos which survive for 4-6 days are more likely to produce the fruitful results.
This enables embryologists to select from the more advanced embryos with better
potential for implantation.
The biggest advantage of Blastocyst Culture and Transfer method is that it significantly
reduces the risk of multiple pregnancies. Also, the pregnancy and implantation success
rate is higher in this technique because it is easy to determine the robust embryos
after developing for 4-6 days hence only the competent embryo are transferred to
uterus.
