Development of an optimal protocol to induce capacitation of boar spermatozoa in vitro

Journal of Animal Reproduction and Biotechnology, 2022
In 1951, Colin Russell Austin and Min Chueh Chang identified “capacitation”, a special process involving ejaculated spermatozoa in the female reproductive tract.

piR-121380 Is Involved in Cryo-Capacitation and Regulates Post-Thawed Boar Sperm Quality Through Phosphorylation of ERK2 via Targeting PTPN7

Frontiers in Cell and Developmental Biology, 2022
Cryopreservation induces capacitation-like (cryo-capacitation) changes, similar to natural capacitation, and affects the fertility potential of post-thawed sperm. The molecular mechanism of sperm cryo-capacitation during cryopreservation remains unknown.

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

Redox 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).

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 ...

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.

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

PLoS 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.

Energy Metabolism and Hyperactivation of Spermatozoa from Three Mouse Species under Capacitating Conditions

Cells, 2022
Mammalian sperm differ widely in sperm morphology, and several explanations have been presented to account for this diversity. Less is known about variation in sperm physiology and cellular processes that can give sperm cells an advantage when competing ...

Human sperm chaperone HSPA2 distribution during in vitro capacitation [PDF]

, 2021
Human fertilization success depends on the ability of the spermatozoa to undergo capacitation. Even though this process can be conducted in vitro, the optimal time for a sperm cell to complete capacitation in vitro is still under discussion due to the ...

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 ...

Potential Role of Acetylation on Equine Sperm Capacitation [PDF]

, 2021
A series of biochemical and physical modifications in the sperm during the transport in the female reproductive tract that make the sperm capable of fertilization are called capacitation.
