Abstract:

Oocyte activation deficiency (OAD) is a common cause of failure of intracytoplasmic sperm microinjection (ICSI). The occurrence of OAD is usually related to the inability of sperm to produce sufficient amount of phospholipase C-ζ (PLCζ), causing calcium (Ca2 +) oscillation to activate oocytes. In order to solve OAD and improve the success rate of ICSI, the research and clinical application of artificial oocyte activation (AOA) are becoming more and more extensive. However, its biological safety has not been fully determined. It is necessary to clarify the role of Ca2 + in oocyte activation, summarize the principles of different activators and their current status in clinical application, and explore the safety and application prospect of AOA technology.

Key words: artificial oocyte activation (AOA), oocyte activation deficiency (OAD), intracytoplasmic sperm microinjection (ICSI), calcium oscillation
