assisted hatching

Examples
The optimization of ART conditions such as an adequate embryo culture, a suitable assisted hatching and [...], could all contribute to ensure the production of good-quality embryos that reduce the risk of implantation failure (Coughlan, 2018; Das & Holzer, 2012).
Among embryos that underwent assisted hatching on days 5-7, hatching was performed at the time of biopsy for 16.5% and before the day of biopsy for 83.5%.
