After the egg retrieval process, my eggs were taken for lab work.
The day of the egg retrieval was considered as day 0 and we received calls from the lab on days 1, 2, 3, 5 and 6.
On Day 1, we were told that out of the 24 eggs retrieved, 18 were mature enough for ICSI (Intracytoplasmic Sperm Injection) and 16 were fertilised in the end.
On Day 2, out of the 16 fertilised eggs, 15 developed into embryos, and gradings were given as follows:
5 of Grade 2 +
6 of Grade 2
4 of Grade 2-
The diagram below shows what the gradings mean:
On Day 3, we were given an update on the gradings of the embryos. 1 embryo was downgraded from Grade 2+ to Grade 2.
4 of Grade 2+
7 of Grade 2
4 of Grade 2-
On Day 5, out of the 15 embryos, only 4 became blastocysts. For the remaining 11, 3 were dead and 8 were kept for another day and see how they would develop.
For those 4 blastocysts, gradings consist of a number and 2 letters were given.
5BB
4BB
3BB
4BC
The number shows the degree of cavity expansion:
The first and second letters show the inner cell mass and appearance of trophectoderm layer respectively:
On Day 6, we were told that those 8 embryos which were pending development into blastocysts did not make it in the end. As a result, we only have 4 blastocysts in total. Biopsy was performed and the cells will be taken for PGT-A (to identify embryos affected by chromosomal abnormalities that will affect an embryo by chance) and PGT-M (to help prevent certain diseases or disorders from being passed on to the child from the parent). The results will be available in around 4 weeks.
We were surprised that out of the 24 eggs retrieved, only 4 managed to make it to this stage. Fingers crossed for lab work part 2 and hopefully I don't need another cycle of injection.
