Changes in calcium transport in mammalian sperm mitochondria and plasma membranes caused by 780 nm irradiation.


BACKGROUND AND OBJECTIVE Regulation of intracellular Ca2+ concentrations are very important in control of sperm motility and acrosome reaction. It was shown previously that low-power lasers in the visible and near-infrared range alter Ca2+ uptake by sperm cells. In the present work the effect of a 780 nm diode laser on Ca2+ uptake by sperm mitochondria and… (More)
