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.

Between Equity and Differentiation: An Analytical schema of the social function of education

International Journal of Sociology of Education, 2013
The educational sphere has an internal function relatively agreed by social scientists. Nonetheless, the contribution that educational systems provide to the society (i.e., their social function) does not have the same degree of consensus.

Expression of Tas1 taste receptors in mammalian spermatozoa [PDF]

, 2012
Background: During their transit through the female genital tract, sperm have to recognize and discriminate numerous chemical compounds. However, our current knowledge of the molecular identity of appropriate chemosensory receptor proteins in sperm is ...

Mitochondrial Activation and Reactive Oxygen-Species Overproduction during Sperm Capacitation are Independent of Glucose Stimuli

Antioxidants, 2020
Spermatozoa capacitation is a complex process that requires specific ionic and energetic conditions to support biochemical alterations leading to motility hyperactivation. However, human sperm capacitation is still poorly understood.

Influence of in vitro capacitation time on structural and functional human sperm parameters

Asian Journal of Andrology, 2020
A cascade of dramatic physiological events is linked to the sperm acrosome reaction and binding to the oocyte's zona pellucida during human sperm capacitation.

Osteopontin enhances sperm capacitation and in vitro fertilization efficiency in boars

Journal of Animal Science and Technology, 2022
In this study, we used more reliable experimental materials and methods to detect the effects of osteopontin (OPN) on boar sperm in vitro capacitation, acrosome reaction, and fertilization efficiency.

Capacitation promotes a shift in energy metabolism in murine sperm

Frontiers in Cell and Developmental Biology, 2022
In mammals, sperm acquire fertilization ability after a series of physiological and biochemical changes, collectively known as capacitation, that occur inside the female reproductive tract. In addition to other requirements, sperm bioenergetic metabolism

Bioenergetics of Mammalian Sperm Capacitation [PDF]

, 2014
After ejaculation, the mammalian male gamete must undergo the capacitation process, which is a prerequisite for egg fertilization. The bioenergetics of sperm capacitation is poorly understood although its fundamental role in sustaining the biochemical ...

Adhesion to oviduct glycans regulates porcine sperm Ca2+ influx and viability.

PLoS ONE, 2020
Before fertilization, sperm bind to epithelial cells of the oviduct isthmus to form a reservoir that regulates sperm viability and capacitation. The sperm reservoir maintains optimum fertility in species, like swine, in which semen deposition and ...

RESEARCH CONCERNING THE INFLUENCE OF CAPACITATION CONDITIONS ON THE QUALITY OF SPERMATOZOA USED FOR IN VITRO FERTILIZATION

Scientific Papers Animal Science and Biotechnologies, 2023
The optimization of capacitation technique is based on the study of the influence factors of this process. Studying the influence of capacitation conditions on boar sperm quality we concentrated our research upon capacitation technique and method.
