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

Asian Journal of Andrology, 2020 The acrosome reaction is a prerequisite for fertilization, and its signaling pathway has been investigated for decades. Regardless of the type of inducers present, the acrosome reaction is ultimately mediated by the elevation of cytosolic calcium ...

EFFECT OF DIFFERENT L-ARGININE CONCENTRATIONS ON IN VITRO BUFFALO SEMEN FERTILIZING POTENTIALS [PDF]
Assiut Veterinary Medical Journal, 2016 Sperm capacitation and acrosome reaction are essential for fertilization. L-Arginine plays an important role in the physiology of spermatozoa and has been shown to enhance their metabolism and maintain their motility.

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 ...

Frontiers in Cell and Developmental Biology, 2021 Human zona pellucida (ZP) matrix is composed of four glycoproteins designated as ZP glycoprotein -1 (ZP1), -2 (ZP2), -3 (ZP3), and -4 (ZP4). Mutations in the genes encoding human ZP glycoproteins are one of the causative factors leading to abnormal ZP ...

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.
