The biochemistry of the acrosome reaction [PDF]
Molecular Human Reproduction, 1997 The binding of the spermatozoon to the oocyte zona pellucida (ZP) occurs via specific receptors localized over the anterior head region of the spermatozoon. Zona pellucida binding stimulates the spermatozoa to undergo the acrosome reaction resulting in the release of hydrolytic enzymes and in the exposure of new membrane domains, both of which are ...

Effect of Uncoated Magnetic Nanoparticles on Stallion Sperm Parameters: Influence of Semen Quality. [PDF]
Reprod Domest AnimABSTRACT The aim of this study was to evaluate the effect of uncoated, non‐functionalised magnetic nanoparticles (MNPs) on stallion sperm and to determine whether these effects depend on initial semen quality. Ten cooled ejaculates from 3 stallions were exposed to different MNP concentrations ([MNPs] = 0, 5, 25, and 50 mg/mL), agitated, and exposed to ...

Genes Regulating Spermatogenesis and Sperm Function Associated With Rare Disorders
Frontiers in Cell and Developmental Biology, 2021 Spermatogenesis is a cell differentiation process that ensures the production of fertilizing sperm, which ultimately fuse with an egg to form a zygote.

Acrosome reaction is subfamily specific in sea star fertilization [PDF]
, 2006 In the fertilization process of sea stars, sperm is activated to go through the acrosome reaction before cell fusion. We focused on induction of the acrosome reaction as a key process in fertilization.

An Overview of The Globozoospermia as A Multigenic Identified Syndrome [PDF]
International Journal of Fertility and Sterility, 2019 Acrosome plays an integral role during fertilization and its absence in individuals with globozoospermia leads to failure of in vitro fertilization (IVF) and oocyte activation post-intracytoplasmic sperm injection (ICSI).
