Artificial oocyte activation and intracytoplasmic sperm injection
Fertility and Sterility, 2010To review different methods for artificial oocyte activation and its impact on intracytoplasmic sperm injection (ICSI).Literature review.University-based and university-affiliated medical centers.None.None.None.The ICSI procedure improves fertilization rates in cases of male factor infertility; however, fertilization failure still occurs in 2% to 3% of

Artificial oocyte activation with calcium ionophore for frozen sperm cycles [PDF]
Systems Biology in Reproductive Medicine, 2018 Fertilization problems are the major problems that may be faced in 30-55% of the patients during an intracytoplasmic sperm injection (ICSI) cycle. A successful oocyte activation depends on factors related to both sperm and oocyte, and one of the important factors that mediates the process is Ca2+ concentration within the oocyte.

Health of Children Born Through Artificial Oocyte Activation
Reproductive Sciences, 2015Artificial oocyte activation (AOA) has shown to improve fertility in severe male infertility following intracytoplasmic sperm insemination (ICSI). However, the effect of AOA on the health status of children has not been studied. This pilot historical cohort study aims to evaluate physical and mental health of 79 and 89 children from 275 and 406 couples

Cryobiology, 2017
Sucrose and trehalose are conventional cryoprotectant additives for oocytes and embryos. Ethanol can artificially enhance activation of inseminated mature oocytes. This study aims to investigate whether artificial oocyte activation (AOA) with ethanol can promote the development competence of in vitro matured oocytes.

Artificial activation of porcine oocytes matured in vitro
Molecular Reproduction and Development, 1991AbstractThese studies were undertaken to understand the biological basis of artificially induced activation of meiotic metaphase II oocytes and to develop a source of oocytes as recipients for cloning by nuclear transfer. In vitro matured porcine oocytes were pulsed with various voltages of electricity and evalulated for pronuclear formation.

In vitro maturation and artificial activation of donkey oocytes
Theriogenology, 2011Three media were evaluated for their ability to support in vitro maturation of donkey (Equus asinus) oocytes and their development after parthenogenetic activation. The basal medium for Medium 1 (M1) and Medium 2 (M2) was M199 and DMEM/F12 respectively, whereas, Medium 3 (M3) consisted of equal parts (v/v) of M199 and DMEM/F12.
