Increased mitochondrial activity upon CatSper channel activation is required for mouse sperm capacitation

open access: yesRedox Biology, 2021
To fertilize an oocyte, sperm must undergo several biochemical and functional changes known as capacitation. A key event in capacitation is calcium influx through the cation channel of sperm (CatSper).

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

open access: yesAsian 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.

Redox regulation of mammalian sperm capacitation

open access: yesAsian Journal of Andrology, 2015
Capacitation is a series of morphological and metabolic changes necessary for the spermatozoon to achieve fertilizing ability. One of the earlier happenings during mammalian sperm capacitation is the production of reactive oxygen species (ROS) that will ...

Mammalian sperm capacitation: In vivo and in vitro juxtaposition

open access: yesVeterinary Integrative Sciences, 2022
The development of assisted reproductive technologies (ART) in mammalian species such as in vitro embryo production (IVEP) has the potential to provide great benefits for significant population increase, improve genetic performance and ...

Osteopontin enhances sperm capacitation and in vitro fertilization efficiency in boars

open access: yesJournal 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

open access: yesFrontiers 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

Seminal CD38 Enhances Human Sperm Capacitation through Its Interaction with CD31. [PDF]

open access: yesPLoS ONE, 2015
Human sperm have to undergo a maturational process called capacitation in the female reproductive tract. Capacitation confers upon the sperm an ability to gain hypermotility and undergo acrosome reaction.

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

open access: yesPLoS 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

open access: yesScientific 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.

Specific lectin binding sites during in vitro capacitation and acrosome reaction in boar spermatozoa

open access: yesItalian 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.
