Early rescue oocyte activation at 5 h post-ICSI is a useful strategy for avoiding unexpected fertilization failure and low fertilization in ICSI cycles

Frontiers in Endocrinology
IntroductionAttempts to artificially activate unfertilized oocytes at 24 h post intracytoplasmic sperm injection (ICSI) have generally resulted in poor outcomes.

A Comparison of chromatin structure and PLCζ in sperms of subfertile oligoasthenoteratozoospermic and fertile men [PDF]

, 2016
زمینه و هدف: مهم ترین علل عدم فعال شدن تخمک پس از تکنیک های کمک باروری، عدم رهایش فاکتورهای اسپرمی فعال کننده تخمک و آسیب به DNA اسپرم است. PLCζ یکی از فاکتورهای اسپرمی است که در فعال شدن تخمک نقش دارد.

Effects of light wavelength on oocyte maturation, parthenogenesis, and parthenogenetic embryo development in pigs

The Journal of Reproduction and Development
Assisted reproductive technologies (ART) to generate developmentally competent oocytes necessitates light exposure due to the use of microscopes. Previous studies in several species have reported that the wavelength of light during the light exposure ...

Oocyte activation with phospholipase Cζ mRNA induces repetitive intracellular Ca2+ rises and improves the quality of pig embryos after intracytoplasmic sperm injection

The Journal of Reproduction and Development
For the intracytoplasmic sperm injection (ICSI) procedure in pigs, an electrical pulse (EP) has been used as an effective method for oocyte stimulation, but unlike sperm, EP is unable to induce Ca2+ oscillations.
