Blastocyst is an embryo that develops after five to seven days of fertilization. It is a thin-walled hollow structure in early embryonic development. It contains cluster of cells called the inner cell mass. The outer layer of the cell gives rise to the supporting tissues for the uterus while the inner gives rise to the tissues of the body.

Blastocyst culture – a new approach to give birth to a child

  1. 1. Blastocyst Culture – A New Approach to Give Birth to a Childhttp://www.delhi-ivf.comBlastocyst is an embryo that develops after five to seven days of fertilization. It is a thin-walled hollow structure in early embryonic development. It contains cluster of cells calledthe inner cell mass. The outer layer of the cell gives rise to the supporting tissues for theuterus while the inner gives rise to the tissues of the body.Blastocyst culture is a selection of the best quality embryos for the transfer to the uterus ofthe mother. The quality of the embryo is very important for the couple who areexperiencing infertility. As Blastocyst culture transfers selected embryos to the uterus of themother the risk of multiple pregnancies reduces and so the danger of miscarriage keepingoverall pregnancy rates high.After few days the cell in the Blastocyst starts differentiating. The differentiation whichcannot be seen in the early Blastocyst with small cavity can be visualised properly by now.Just under the outer shell the surface cells that surround the cavity are called thetrophectoderm. The cells which are at the centre of the group of cells are called the innercells mass which later form into foetus.Advantages and Disadvantages of the Blastocyst cultureNormally two to three day old embryo are normally found in the fallopian tube and not inthe uterus. After ovulation the first uterus moves into the uterus for approx 80 hours. Asembryo implantation process begin Blastocyst formation and hatching out of the embryonicshell occurs within 3 days. The chances of transfer of Blastocyst embryo can be done in fivedays if healthy Blastocyst forms at a high rate. By Blastocyst culturing if we realise that someof them have not become Blastocyst we always have an opportunity to choose the mostbest embryo to transfer. So even if the rates of the embryo are less but the quality is greatthen yet there are chances of obtaining high pregnancy success ratesIf this 5embryo Blastocyst transfer is delayed even little bit then the chances of the highquality goes down. Therefore if the quality control and the test culture system is in the IVF
