Examples
In a total of n = 402 ART cycles, Guarneri et al. specifically evaluated the use of two different oxygen concentrations (atmospheric versus low oxygen) during oocyte culture from recovery until decumulation on day 1, followed by use of low oxygen concentration (5%) until transfer.
Flushing medium (Origio, Denmark) containing 300 μg/mL hyaluronidase (Sigma-Aldrich, USA) and 140 μm Flexipet pipettes adjusted to Flexipet handle (Cook Medical, USA) were used for COC decumulation.
