They identified three criteria: a first cytokinesis lasting up to 33 minutes, an interval of 7.8-14.3 hours between the first and second mitoses, and an interval of up to 5.8 hours between the second and third mitoses. Use of these observations could lead to an improved pregnancy rate with in vitro fertilisation.
