After consulting a professional doctor, we know that semen can only survive for half a day at room temperature. After the sperm is extracted, it is sent to a common refrigerator to cool to 4 ° C, and then it is cooled to minus 25 ° C in a freezer. The third step is to freeze the semen into a liquid nitrogen tank at minus 196 ° C. After 6 months, all the test items of the sperm donors are up to standard, and the longest 'window period' from HIV infection to antibody production will be passed before it can be officially provided to those in need.
During an interview in the sperm storage, the staff wore frostbite-resistant gloves and pulled a container that had frozen dozens of tubes of sperm out of the liquid nitrogen tank. A white mist erupted in the storage immediately. A few seconds later, the staff hurriedly put the sperm back into the liquid nitrogen tank.
