Blastocyst Treatment for Infertility?
With the advancing technology in every sphere of life, infertility treatment methods have also developed. Blastocyst treatment cannot be considered upgraded technology of treating infertility but a novel method for a particular problem of infertility. While ICSI is mainly used for treating male infertility, Blastocyst technology is used to improve chances of conceiving. The methodology is generally recommended when the woman has produced good quality of embryos but they failed to get implanted in the womb.
In simple terms, Blastocyst treatment is used to better the chances of implanting embryos in the womb. Considering the high probability of conceiving with the Blastocyst treatment, only a single embryo is transferred to the womb. That takes care of the risk of multiple births.
What is Blastocyst technology?
In Blastocyst technology, embryos are cultured for Day 5-6 after co-incubation and then transferred to the uterus as compared to the treatment given in IVF at the cleavage stage i.e. 2-4 days after co-incubation. At the Blastocyst stage, it becomes easier for the treating doctors to select the best quality of embryos. Your treating doctors will not recommend undergoing Blastocyst transfer in case you produce less number of eggs. In that scenario, they will prefer IVF only.
Blastocyst helps in Embryos selection
As explained above, Blastocyst is an embryo that is cultured in the lab for five to six days after insemination. That means the embryo is advanced is to the day-6 stage. While reaching this stage, it gets divided into many more cells during this period. Blastocysts, having a very thin outer shell, have increased chances of implantation into the uterine cavity. Most blastocysts hold a fluid cavity and it is easier for the doctors to see and identify the cells that have the potential of becoming a baby.
As against a large chunk of 3-day embryos, only 40 per cent of these embryos develop into blastocysts. These select embryos have a much higher chances of pregnancy and, thus, have a higher live birth rate.
Better conditions in womb and Fallopian tubes
Many researchers are of the opinion that the conditions are more conducive for pregnancy at Blastocyst stage than the conventional Day-2 or Day-3 Embryo Transfer.
Blastocyst Transfer helps in higher pregnancy rate
While infertility conditions of each couple have to be considered and treated independently, the available data leads to believe that blastocyst transfer gives increased chances of a live birth.
Blastocyst gives confirmation of embryo development
Specialists in the infertility treatment field are of firm belief that with the extended culture, the quality of embryo can be examined at the minute level. With this, repeated implantation failure can be examined and arrested. If the embryos stop developing after a stage or get fragmented, this would help them in diagnosing a potential problem.
Blastocyst transfer for specific reasons
Blastocyst transfer will be viable option in the following situations:
History of multiple pregnancy;
Blastocys Transfer with Frozen Embryos
In some patients, there are a large numbers of frozen embryos. That makes it difficult to know which one has the best prospect for pregnancy. Melting all embryos and culturing them through to the blastocyst stage helps in identifying the best one or two embryos.
The foremost benefit
The most important advantage of the blastocyst transfer line of treatment is its ability to distinguish between embryo as per their quality and implantation probability. It is pertinent to know that the extended culture process of Blastocyst doesn’t increase the quality of any embryo, but it is a method for choosing the front-runner embryo from the group.
