- On the day of the ovum pick up make center well with cleavage medium and kept overnight in the incubator.
- The next day (day 1) after the denudation (IVF embryos) and PN assessment is done (IVF and ICSI embryos) the selected embryos are put in the culture medium
- This is done with a 170um flexi pipette.
- The dishes are then put in the incubator at 37*C and 6% Co2.
- On Day 2 a dish with cleavage media is made in the same way and kept in the incubator. The embryos in the cleavage media are assessed for cleavage and graded.
- On day 3 the embryos from culture media are then tranferred into well containing fresh culture medium.
- The embryos are generally at the eight cell stage.
- On day 4 the embryos are not touched but a transfer dish (0.8 ml ml G2.2 media in center well) is prepared for the blastocyst transfer the next day.
- On day 5 the embryos are assessed. The blastocyst from embryos with high PN scores on Day 1 are given priority.
- The blastocyst are washed in a wash dish, this time a 300um pipette is used and then transferred to the final Embryo transfer dish.
