2016年5月30日消息,西安。根据国内权威精子库的检查报告,正常成年男性精子的合格率不到30%。西北妇幼医院人类精子库2015年捐精1000人,合格的只有100人,但精配1400人。专家说,精子一年不如一年,但对精子的需求越来越大。不到30%的合格率背后,随着二胎政策的全面放开,国内对精子的需求越来越大。如何有效地储存精子样本也是国内各大精子库的一大考验!让精子永远“年轻”,-196℃液氮罐也广泛应用于各大精子库!精子永远“年轻”的秘密采集精液后,取少量做抽样检查,其余的加入保护剂,放入美龄生物医用液氮罐中(-196℃)冷冻起来。当需要时,精子样本管在37°C的水浴中解冻。液氮罐温度为-196℃,此时精子代谢处于最低水平,降低代谢可长期存活。 In theory, these sperm samples can be stored in liquid nitrogen tank for several years, decades or even a hundred years. Foreign literature has reported that 30 years after the resurrection of sperm frozen can still produce healthy offspring. Meiling liquid nitrogen tank use, not only in the life incubation period, more likely to be some people's life-saving straw. In recent years, the promotion of umbilical cord blood stem cells increased, the stem cell treatment prospects, Cord blood stem cells are not only rich in content, and immune rejection is relatively mild, can treat leukemia, cancer and other 80 kinds of diseases, baby and family can , Is a very good stem cell source. The same is the liquid nitrogen cans, cord blood in the umbilical cord blood bank as a "home" for the preservation of umbilical cord blood has an irreplaceable role. January 27 is the opening day of autologous umbilical cord blood in Beijing, in Beijing cord blood bank of 1,500 square meters of liquid nitrogen library in neatly arranged with hundreds of the world's largest single storage silver liquid nitrogen cans, more than 200,000 baby's umbilical cord Blood was stored in these -196 ° C liquid nitrogen tanks. In order to ensure the safety of umbilical cord blood, the liquid nitrogen reservoir is equipped with 24-hour closed-circuit monitoring, infrared alarm, dual-circuit power supply and the liquid nitrogen level of 24 hours monitor. Meiling Bio-medical liquid nitrogen tank and wireless intelligent monitoring system with the perfect, in the sperm, embryos and umbilical cord blood and other storage process, can effectively monitor the biological samples in the tank to protect biological samples of the safety and stability.
