BACKGROUND Oocyte activation deficiency (OAD) is attributed to the majority of cases
underlying failure of ICSI cycles, the standard treatment for male factor infertility. Oocyte …

Oocyte activation, a fundamental event during mammalian fertilisation, is initiated by
concerted intracellular patterns of calcium (Ca2+) release, termed Ca2+ oscillations …

Bacteriospermia is a documented risk to sperm quality when boar semen is stored at 17° C.
The objective of this study was to evaluate the effects of kojic acid (KA) on sperm quality and …

Maternal mitochondrial inheritance is a fundamental paradigm within reproductive biology,
yet the molecular mechanisms which underlie this process remain poorly understood. The …

Low motility and low sperm concentration are characteristics of alpaca semen. Thus, the
intracytoplasmic sperm injection (ICSI) technique represents an alternative to improve the …

Oocyte activation occurs at the time of fertilization and is a series of cellular events initiated
by intracellular Ca2+ increases. Consequently, oocytes are alleviated from their arrested …

Mobile zinc is an abundant transition metal ion in the central nervous system, with pools of
divalent zinc accumulating in regions of the brain engaged in sensory perception and …

Embryo development is stimulated by calcium (Ca2+) signals that are generated in the egg
cytoplasm by the fertilizing sperm. Eggs are formed via oogenesis. They go through a cell …

Zinc (Zn) is an essential trace element with anti-inflammatory and antioxidant effects and
plays a crucial role in the female reproductive system. We aimed to investigate the protective …

Mammalian oocyte activation is a critical process occurring post-gamete fusion, marked by a
sequence of cellular events initiated by an upsurge in intracellular Ca 2+. This surge in …
