When the embryos are only eight cells large , an embryologist very carefully makes a hole in each shell , and sucks out a single cell to be tested genetically .
Eggs of varying quality from my uterus this morning , it took pain meds , a doctor , nurses , a catheter , an ultrasound machine worth more than my house , a microscope , and an embryologist .
Several days later , the embryologist looks at her petri dishes under a microscope to see whether any of the eggs has transformed into a blastocyst-the cluster of five cells that will eventually divide and divide again until it becomes a baby .
