Acrosome reaction: relevance of zona pellucida glycoproteins [PDF]
Asian Journal of Andrology, 2010 During mammalian fertilisation, the zona pellucida (ZP) matrix surrounding the oocyte is responsible for the binding of the spermatozoa to the oocyte and induction of the acrosome reaction (AR) in the ZP-bound spermatozoon. The AR is crucial for the penetration of the ZP matrix by spermatozoa.

The Modulation of Functional Status of Bovine Spermatozoa by Progesterone
Animals, 2021 The aim of this study is to identify the effects of progesterone (PRG) on the capacitation and the acrosome reaction in bovine spermatozoa. The fresh sperm samples were incubated with and without capacitation inductors (heparin, dibutyryl cyclic ...

Indian Journal of Animal Sciences, 2022 Acrosome intactness of spermatozoa is the critical factor for establishing sperm reservoir in oviduct and for fertilizing an oocyte. However, frozen thawed spermatozoa tend to show higher proportion of acrosome reacted spermatozoa thereby compromising ...

The testicular form of angiotensin converting enzyme as a marker for human sperm quality assessment [PDF]
Folia Medica, 2023 Introduction: Spermatozoa are rapidly changing cellular structures that are highly dependent on their interaction with the environment. These interactions cause fundamental changes in the spermatozoa’s cells and membrane. All physiological changes

Versatile action of picomolar gradients of progesterone on different sperm subpopulations. [PDF]
PLoS ONE, 2014 High step concentrations of progesterone may stimulate various sperm physiological processes, such as priming and the acrosome reaction. However, approaching the egg, spermatozoa face increasing concentrations of the hormone, as it is secreted by the ...

Specific lectin binding sites during in vitro capacitation and acrosome reaction in boar spermatozoa
Italian Journal of Animal Science, 2021 Sperm glycocalyx and plasma membrane undergo outstanding modifications during fertilization. However, it is unclear how in vitro capacitation time and acrosome reaction affect the specific location of boar sperm glycoconjugates.
