Embryo ivf stages

Day 3: Human embryo at the 8-cell stage (approximately 72 hours after insemination). Embryos that are late stage 3 and higher, and with A or B grades are biopsied and frozen on Day 5, 6, or 7. Early stage 3 embryos will remain in culture overnight to allow the embryo time to develop more cells, resulting in better survival of the biopsy procedure. If the transfer is on day 3, the embryos chosen for transfer are usually at the 6-8 cell stage. By day 5, the embryos should be at the blastocyst stage at which time each embryo contains approximately 100-120 cells.

Day 1 – After the embryos are transferred, the cells keep dividing. The blastocyst begins to emerge from its shell and this process is called hatching. Day 2 – The second day is crucial because this is the time when the embryo begins to attach itself to the uterine lining. The blastocyst continues to grow.

This may be done in cases of severe male infertility, previously cryopreserved eggs, preimplantation genetic testing of embryos (PGT), or if past IVF cycles have failed at the fertilization stage. But before eggs can be retrieved, the ovaries must be stimulated. IVF involves several steps — ovarian stimulation, egg retrieval, sperm retrieval, fertilization and embryo transfer.

Do’s and Don’ts After Embryo Transfer. Bed rest: Bed rest is advised while at the clinic after the embryo transfer is performed. Implantation takes place between 1 and 5 days after a blastocyst transfer. If you had a day-3 transfer, your implantation window is 6 to 10 days after egg retrieval.

It is at the blastocyst stage of development (five days after fertilisation) that an embryo would normally move out of the fallopian tube and into the uterus. There can also be excellent reasons to grow an embryo to the cleavage stage, stop there, and transfer it.
