[ใหม่] ทำไมไนโตรเจนเหลวไม่สามารถฆ่าสเปิร์มได้

Liquid nitrogen is a low temperature liquid nitrogen, the temperature is as low as -196 degrees Celsius, but we often use it to freeze sperm to maintain sperm activity, so why can sperm remain active at such a low temperature? Why does liquid nitrogen not freeze sperm?
Under normal circumstances freezing would cause the water inside the cells to freeze, thus causing damage to the cells and theoretically to the sperm as well. In fact, only 0.1 percent of sperm remain active after thawing when they are frozen in a Dewar's vial with liquid nitrogen without any measures. In order to reduce the damage caused by freezing, a special cryoprotectant is added to the sperm before they are placed in the Dewar's vial with a freezing tube. This allows the sperm to be effectively protected in the freezing process and to lie dormant in liquid nitrogen in a relatively constant state. To better preserve sperm in liquid nitrogen, we need the more trustworthy Dewar bottle.
