Blastocyst Culture
The growth of medical science has made it possible to achieve so many things that one could not have possibly imagined a few decades ago. The formulation of the liquid in which in vitro culture is done to grow the embryo has made it possible to grow the embryo beyond the usual 3 day time period. Embryo can now be cultured in vitro for up to 5 days until it becomes a blastocyst which is the final stage of the embryo’s development before it comes out of the egg by breaking the zona pellucida and then plant itself in the uterine wall.
Why Is ItDone?
Embryo transfer on the fifth day, at the blastocyst stage, has higher pregnancy rates. There might be two conceivable explanations behind this:
Initially, transfer of the blastocyst to the uterus might be all the more physiologically suitable, since this imitates nature all the more intently, with the goal that the implantation rate might be higher.Additionally, holding up till the blastocyst stage enables the specialist to choose the best embryo since undesirable fetuses are probably going to arrest before they achieve this stage.
Blastocyst transfer fundamentally diminishes the likelihood of possibly dangerous twin or triplet birth. Higher implantation rates enable specialists to exchange fewer blastocysts – maybe just a single – decreasing or keeping away from multiple births and their related issues. Supernumerary blastocysts can likewise be effectively cryopreserved utilizing vitrification with the goal that pregnancies can be accomplished later. Read more
