Osteopontin enhances sperm capacitation and in vitro fertilization efficiency in boars [PDF]
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.

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

Time to revise: impact of methodology on boar sperm capacitation in vitro via phosphotyrosine patterns [PDF]
Capacitation is a crucial sperm maturation process occurring in vivo in the female reproductive tract, enabling spermatozoa to fertilize the oocyte. In vitro, capacitation can be induced using defined capacitation media (CM), with further assessment of ...

Cordycepin improves hyperactivation and acrosome reaction through adenosine receptors during human sperm capacitation in vitro [PDF]
Background Sperm capacitation is a prerequisite for natural or in vitro fertilization. After capacitation, sperm become hyperactivated and undergo an acrosome reaction, which helps them penetrate the oocyte.

Quantitative phosphoproteomics analyses reveal the regulatory mechanisms related to frozen-thawed sperm capacitation and acrosome reaction in yak (Bos grunniens) [PDF]
Mammalian spermatozoa are not mature after ejaculation and must undergo additional functional and structural changes within female reproductive tracts to achieve subsequent fertilization, including both capacitation and acrosome reaction (AR), which are ...

New insights into posttranslational modifications of proteins during bull sperm capacitation [PDF]
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).

Bottom-up approach to deciphering the targets of the ubiquitin-proteasome system in porcine sperm capacitation [PDF]
Capacitation is an essential post-testicular maturation event endowing spermatozoa with fertilizing capacity within the female reproductive tract, significant for fertility, reproductive health, and contraception.

Sperm capacitation in bulls, rams, bucks, and boars: molecular mechanisms and species-specific differences [PDF]
Capacitation is the process by which sperm undergoes physical, biochemical, and molecular changes to acquire the ability to fertilize an oocyte.

Citrate Promotes Nitric Oxide Production during Human Sperm Capacitation [PDF]
Sperm capacitation is a complex process essential for the spermatozoon to recognize and fertilize the oocyte. For capacitation to occur, human spermatozoa require low levels of reactive oxygen species (ROS), increased protein tyrosine phosphorylation ...

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