WebBackground: The objective of the study was to investigate the developmental fate of oocytes with increased cytoplasmic viscosity as assessed by the persistence of the injection funnel after withdrawal of the ICSI pipette. Methods: For this purpose, 1008 oocytes showing a characteristic injection funnel during ICSI were subdivided into two groups according to …
WebIn continuum mechanics, time-dependent viscosity is a property of fluids whose viscosity changes as a function of time. The most common type of this is thixotropy, in which the viscosity of fluids under continuous shear decreases with time; the opposite is rheopecty, in which viscosity increases with time. Thixotropic fluids [ edit]
