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 ...

Sperm Capacitation and Kinematics in Phodopus Hamsters. [PDF]
Int J Mol Sci, 2023 This study was designed to analyze changes in the spermatozoa of three species of Phodopus hamsters incubated under different conditions. Cauda epididymal sperm were incubated for 4 h in modified Tyrode’s medium containing albumin, lactate, pyruvate, and Hepes (mTALP-H), in the same medium with the addition of bicarbonate (mTALP-BH), or with ...

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.

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.

F4-Neuroprostanes: A Role in Sperm Capacitation. [PDF]
Life (Basel), 2021 F4-neuroprostanes (F4-NeuroPs), derived from the oxidative metabolization of docosahexaenoic acid (DHA), are considered biomarkers of oxidative stress in neurodegenerative diseases. Neurons and spermatozoa display a high DHA content. NeuroPs might possess biological activities. The aim of this in vitro study was to investigate the biological effects of

Bioenergetics of Mammalian Sperm Capacitation [PDF]
BioMed Research International, 2014 After ejaculation, the mammalian male gamete must undergo the capacitation process, which is a prerequisite for egg fertilization. The bioenergetics of sperm capacitation is poorly understood despite its fundamental role in sustaining the biochemical and molecular events occurring during gamete activation.

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.
