Human sperm chaperone HSPA2 distribution during in vitro capacitation [PDF]
Journal of Reproductive Immunology, 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 ...

NADPH Oxidase 5 and Melatonin: Involvement in Ram Sperm Capacitation [PDF]
Frontiers 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

Redox regulation of mammalian sperm capacitation
Asian 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 ...

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.

Bull Sperm Capacitation Is Accompanied by Redox Modifications of Proteins
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 ...

Mammalian sperm capacitation: In vivo and in vitro juxtaposition
Veterinary 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 ...

Citrate Promotes Nitric Oxide Production during Human Sperm Capacitation
AntioxidantsSperm 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 ...

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 ...
