Possibly non-standard use: fragmentation > fracture > “fragčeris”.

“Typically the laboratory denotes the degree of fragmentation by assigning it a grade along a four-point grading scale. One indicates an embryo with little fragmentation (<5%), and four indicates a high degree of fragmentation (>40%) and an embryo that is non-viable. Excessive embryo fragmentation (grade 3-4) is considered a marker for embryos with compromised developmental potential.”

“Within the embryo are many key cellular structures, as well as chromosomes that contain the genetic information required by the embryo, that are all vital for continued normal embryo development. If one of these vital components is expelled from the cells and ends up as part of a fragment it can no longer take part in the progression of the embryo. In this case the likelihood of successful implantation may be affected.”
