Artificial oocyte activation with SrCl2 or calcimycin after ICSI improves clinical and embryological outcomes compared with ICSI alone: results of a randomized clinical trial

Human Reproduction, 2018
STUDY QUESTION Are pregnancy and birth rates affected by artificial oocyte activation (AOA) with SrCl2 or calcimycin after ICSI for couples with male-factor infertility linked to abnormal sperm morphology or for couples with previous ICSI cycles of ...

Effect of culture conditions on artificial activation of porcine oocytes matured in vitro

Reproduction, Fertility and Development, 1996
The effects of culture media used and culture period for in vitro maturation of porcine oocytes on their subsequent response to chemical and electrical activation, were investigated. Activated oocytes were identified by the presence of a pronucleus(ei) or cleavage.

Effect of high fat diet on artificial oocyte activation following superovulation in mice

Zygote, 2015
SummaryThe aim of the present study was to determine the effects of increased dietary intake and high fat diet (HFD) in mice on artificial oocyte activation by using puromycin or roscovitine. Six-week-old mice were fed as either a control diet group, an increased dietary intake group or an HFD group for 4 weeks.

Reconstruction of artificial nuclei with nuclear import activity in living mouse oocytes

Genes to Cells
Abstract In eukaryotes, DNA is housed within the cell nucleus. Molecules required for the formation of a nucleus have been identified using in vitro systems with frog egg extracts and in vivo imaging of somatic cells. However, little is known about the physicochemical factors and conditions required for nuclear formation in mouse ...

Intracellular Ca2+ during fertilization and artificial activation in mouse oocytes.

Zhongguo yao li xue bao = Acta pharmacologica Sinica, 1999
To study the mechanism of oocyte activation in mammals.Mouse oocytes arrested at metaphase of the second meiotic division were loaded with Fura 2-AM and then activated with ethanol, calcimycin, electric pulse or fertilization. Intracellular free Ca2+ during activation were measured by Spex AR-CM-MIC cation system.

[A control study of artificial oocyte activation in the same period].

Zhonghua yi xue za zhi, 2017
Objective: To compare the fertility rate and embryo outcome between normal fertilization and the use of Calcium ionophore A23187 on the same period of the same cycle of human ovum for artificial activation. Methods: Patients who conducted the intracytoplasmic sperm injection (ICSI) cycle in vitro fertilization assisted reproductive from January 2015 to
