Bull Sperm Capacitation Is Accompanied by Redox Modifications of Proteins [PDF]
International Journal of Molecular Sciences, 2021 The ability to fertilise an egg is acquired by the mammalian sperm during the complex biochemical process called capacitation. Capacitation is accompanied by the production of reactive oxygen species (ROS), but the mechanism of redox regulation during ...

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

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).

A Review on the Role of Bicarbonate and Proton Transporters during Sperm Capacitation in Mammals. [PDF]
Int J Mol Sci, 2022 Alkalinization of sperm cytosol is essential for plasma membrane hyperpolarization, hyperactivation of motility, and acrosomal exocytosis during sperm capacitation in mammals.

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

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

Expression of cystatin C in the female reproductive tract and its effect on human sperm capacitation
Reproductive Biology and Endocrinology, 2018 Background Cystatin C (CST3), a cysteine protease inhibitor in seminal plasma, is expressed in animal uteri. However, its expression in the human female reproductive tract and its effect on human sperm capacitation are unclear.

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.

Time to revise: impact of methodology on boar sperm capacitation in vitro via phosphotyrosine patterns [PDF]
BMC Veterinary ResearchCapacitation 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 ...

Zinc ion flux during mammalian sperm capacitation
Nature Communications, 2018 During sperm capacitation physiological changes occur that are required for fertilization. Here, the authors describe four sperm zinc signatures during invitro capacitation that are indicative of sperm quality and capacity to fertilize.
