New hopes and reduced complications with blastocyst transfer
Is there any way to reduce the risks that are in delivering multiples? Yes, it is blastocyst transfer. This not only help couples to become parents but it also erase the complications that are for both the mother and baby. With this technique, only fewer embryos are transferred and increase the chances of getting conceived.
What’s the result with blastocyst transfer?
In a conventional IVF treatment also called as three day transfer method, all the resulting embryos will turn into pregnancies and there is more chance of giving birth to multiple. So this result in many health risks and the couples will be in the dilemma of whether to move with risky pregnancy or to remove the fetuses. But in blastocyst transfer only fewer embryos are transferred that do away the risk of multiple births.
Blastocyst transfer is totally a modernized technique of transferring embryo where the embryo is allowed to grow for five to six days and then it develops into a ball of 120 cells called as blastocyst. Then it is ready to get inserted into the walls of the uterus. At the time of development an embryo stays inside a shell called as zona pellucid. So after five or six days it comes out of the shell and gets attached to the outer surface of uterine. In before coming out of the shell, an embryo turns into blastocyst.
Success rate in blastocyst transfer
In regard to the information released by Human Embryo and Fertilization Authority (HFEA), nearly 32.3 percent of women under the age of 35 are moving to non-blastocyst IVF method. And the percentage of women below 35 who got pregnant with blastocyst transfer method was 147.9 percent. This shows a variation of almost 15 percent and the higher success rate is for blastocyst method. The similar scenario is observed in older women also

Will blastocyst transfer works with ICSI?
ICSI, this is the technique used as a part of IVF when there is insufficient production of sperms by the male partner. On behalf of mixing the sperms and eggs in vitro, the DNA from a single sperm is implanted into each egg for the fertilization to take place. Then the resulted embryos are cultured as they are in an ordinary IVF cycle, and the same choice to wait for blastocysts to form can be made at day 2–3. If these grow well by day 5–6, then blastocyst transfer takes place.
Who are good for blastocyst transfer?Another challenging situation is to choose that who are good candidates for blastocyst transfer. This is good for people who are with large number of oocytes and embryos. And for people those who would not think about fetal reduction or for people where pregnancies would be predominantly unsafe. Blastocyst transfer is probably not advantageous for patients who develop only a few oocytes or embryos, except they decide to make use of extended culture to the blastocyst stage as a diagnostic indicator of embryo quality.
So, the transfer of a single blastocyst will turn into norm and the complications behind the multiple births will be faded out. This creates more hope for a safe delivery.
