Total fertilization failure after ICSI: insights into pathophysiology, diagnosis, and management through artificial oocyte activation.

Human Reproduction Update, 2023
BACKGROUND Total fertilization failure (TFF) is the failure of all metaphase II oocytes to fertilize in ART cycles. The phenomenon represents a known cause of infertility, affecting 1-3% of ICSI cycles.

Requirement of Lysosomal Two-Pore Channels for Normal Fertilization and Artificial Oocyte Activation in Mice.

Frontiers in Bioscience-Landmark
BACKGROUND Lysosomes serve not only in the degradation of cellular components but also as calcium (Ca2+) stores. In this study, we investigated the effects of trans-Ned19, an inhibitor of lysosomal calcium channels known to block two-pore channels (TPCs),

Comparison of clinical artificial oocyte activation protocols on mouse egg activation and embryo development.

Reproduction
Artificial oocyte activation (AOA) with Ca2+ ionophores is an experimental procedure that benefits patients who fail to obtain fertilized eggs. However, the impact of non-physiological Ca2+ increases on cellular events involved in egg-embryo transition ...

Artificial oocyte activation after intracytoplasmic morphologically selected sperm injection: A prospective randomized sibling oocyte study

Human Fertility, 2016
This study aimed to evaluate the effect of artificial oocyte activation (AOA) by calcium ionophore after intracytoplasmic morphologically selected sperm injection (IMSI) on fertilization, cleavage rate and embryo quality. A total of 194 oocytes from 21 cycles from women with a history of low fertilization rate accompanying teratozoospermia were ...

Artificial oocyte activation with ionomycin compared with A23187 among patients at risk of failed or impaired fertilization.

Reproductive Biomedicine Online, 2022
RESEARCH QUESTION Do fertilization rates differ between intracytoplasmic sperm injection (ICSI) cycles treated with artificial oocyte activation (AOA) using 10 µmol/l ionomycin or commercial A23187 in women at risk of failed or impaired fertilization ...
