Blastocyst Transfer

What is a blastocyst stage?

The blastocyst is a stage of the human embryo that it attains after five to six days of fertilisation. It is considered to be a rapidly dividing mass of balls, whose inner group of cells will transform into the embryo.

What is blastocyst transfer?

The blastocyst transfer is one of the invitro-fertilisation techniques in which the fertilised egg is cultured till it transforms into the blastocyst form. At this stage, the blastocyst is implanted into the lining of the uterus (womb). 

In the case of natural embryo development, the blastocyst starts moving out from the fallopian tube into the uterus. This blastocyst naturally starts attaching to the innermost lining of the uterus by the process called implantation. Therefore, the embryo’s chances of implantation into the uterine wall are many times higher in the blastocyst stage than in other stages of embryo development.

How can blastocyst transfer help couples to have a baby?

The couples who choose in-vitro fertilisation to have a child should be aware of the steps of the treatment. At Veda Fertility, you will get complete consultation from fertility experts to understand the procedure easily. The blastocyst is one of the developmental stages of the embryo, which has a higher rate of implantation. The embryo is developed in the lab via the in-vitro method, and technicians observe it until it reaches the blastocyst stage. After this, the most capable blastocyst is transferred into the uterus for implantation. The implanted blastocyst continues the further development in the uterine lining. 

The couple can choose to keep the remaining blastocysts for further good news in later life. In that case, the rest of the blastocysts will be preserved by freezing them.

  • It minimises the risk of multiple pregnancies.

Blastocyst transfer allows the embryologists to observe the embryos for the longest time. The advantage is that the embryologist can identify the best embryos to transfer. One or two healthy embryos are selected with a higher successful implantation rate. Therefore, it increases the treatment’s success rate and minimises the risk of multiple conceptions.

Steps of blastocyst-stage extended culture and transfer

  • Ovarian stimulation

In this stage, ovaries are stimulated with certain medications to produce more eggs. The responses of ovaries to the medication are observed by performing blood tests or ultrasounds to observe the size and quantity of the follicles. After this, the matured eggs start loosening from the follicle wall under the injection of human chorionic gonadotrophins (the trigger). 

  • Egg recovery

After 35 to 38 hours of the trigger, the eggs are retrieved under ultrasound guidance while you are sedated.

  • Fertilisation

For this stage, motile and morphologically normal sperms are collected for insemination. Before insemination, the sperm sample is washed and concentrated. Then, it is injected into the eggs by the process called intracytoplasmic sperm injection (ICSI) approximately four hours after retrieval. The inseminated eggs are observed for 16 to 18 hours for fertilisation. The fertilised embryos are cultured for 2 to 5 days in the lab till they transform into blastocysts.

  • Embryo transfer

The best embryo is chosen for embryo transfer. It is loaded into the transfer catheter, passed via the uterine cervix, and gently released into the uterus.
