IVF Embryoscope

Embryoscope - 12 embryos developing for a 5 day transfer at 2 minute intervals.
Well 2 and 11 become expanding (hatching) blastocysts and are transferred. Wells 4, 10 and 12 become blastocysts but only 2 of those 3 are frozen - not sure why.
Well 1 shows 3 nucleii and Well 3 shows only 1 nucleii so both abnormal. Its a bit of a mixed bag !
