Sperm capacitation in bulls, rams, bucks, and boars: molecular mechanisms and species-specific differences [PDF]

open access: yesFrontiers in Veterinary Science
Capacitation is the process by which sperm undergoes physical, biochemical, and molecular changes to acquire the ability to fertilize an oocyte.

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).

A special perspective on human fertilization: The role of sperm capacitation proteins and channels: A narrative review [PDF]

open access: yesInternational Journal of Reproductive BioMedicine
Sperm undergo a last step of maturation known as capacitation in the female reproductive system, which prepares themselves to fertilize the ovum. Mechanisms of capacitation include changes in membrane composition, electrolyte concentration, pH levels ...

Levels of Protein CoAlation Regulate Redox Signaling Events of Human Sperm Capacitation [PDF]

open access: yesAntioxidants
Infertility is a global health problem, with male factors contributing to nearly half of all cases. Up to 30% of male infertility is classified as idiopathic, in part because routine semen analysis does not assess sperm fertilizing competence ...

Systematic mRNA interactome analysis reconceptualizes translational quiescence in bovine sperm [PDF]

open access: yesCommunications Biology
Ejaculated mammalian sperm must undergo a series of biochemical changes called capacitation to gain fertilizing competence. Mounting evidence on protein synthesis during capacitation contradicts the widely accepted dogma of translational quiescence in ...

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

open access: yesJournal 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

open access: yesFrontiers 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.

New insights into posttranslational modifications of proteins during bull sperm capacitation

open access: yesCell Communication and Signaling, 2023
Background Due to the unique nature of spermatozoa, which are transcriptionally and translationally silent, the regulation of capacitation is based on the formation of posttranslational modifications of proteins (PTMs).

NADPH Oxidase 5 and Melatonin: Involvement in Ram Sperm Capacitation

open access: yesFrontiers in Cell and Developmental Biology, 2021
Reactive oxygen species (ROS) play an essential role in mammalian sperm capacitation. NADPH oxidase 5 (NOX5) has been described as the main source of ROS production in some mammalian spermatozoa, such as human and equine. On the other hand, melatonin can
