Nidacon PureSperm 40/80 – 2×20 mL

PureSperm 40, PureSperm 80 and PureSperm 90 are formulated to minimize sudden pH and osmolarity changes during the transition of sperm from a semen sample to the fertilization medium. This helps avoid premature hyperactivation and improves fertilization potential. PureSperm 40, PureSperm 80 and PureSperm 90 maintain a pH of between 7.4 – 7.8 at room temperature (17 to 27°C) and when incubated at 37°, providing suitable conditions for good sperm motility, survival time, and fertilization potential. These preparations contain glucose as a usable energy substrate for normal cell metabolism and sperm function. The gradient enables motile sperm to be separated from extrawhen incubated neous cells and seminal plasma. In addition, damage to sperm DNA and structural molecules caused by reactive oxygen species (ROS) is minimized by the effective removal of immature sperm and lymphocytes. Bacteria, epithelial cells, and cell debris are also separated from the motile sperm, which can be difficult to achieve in polysucrose-based gradient preparations.
