一、历史回顾人类精子库是超低温冷冻贮存人精子的设备,泛指冷贮人精子的医疗或研究单位。自1776年,Spallanzani发现冰雪可以冷贮人精子以来,人精子冷冻贮存的研究已有200多年的历史。1866年,Mantegazza报道,人精子可耐受-15℃低温冷冻,并最先倡导建立人类精子库(Human Sperm Bank)。限于当时的条件,冷贮的精子只能存活很短的时间。1938年,Jahnel在研究性病时,意外发现存放在玻璃试管内的人精子,经-79、-196、及-269、5℃冷冻并冷贮在-70℃低温中40天,解冻后仍有活动精子。1940年Shettles证实了Jahnel的发现。并发现分装在毛细管内的精子经-269、5℃冷冻后,仍可存
First, the historical review The human sperm bank is cryogenic frozen sperm storage equipment, refers to the cold storage of human sperm or medical research unit. Since 1776, when Spallanzani discovered that snow and ice can cool human spermatozoa, the study on frozen storage of human sperm has been going on for more than 200 years. In 1866, Mantegazza reported that human sperm were able to tolerate cryogenic freezing at -15 ° C and were the first to promote the establishment of the Human Sperm Bank. Due to the prevailing conditions, cryopreserved sperm can only survive for a short period of time. In 1938, Jahnel in the study of sexually transmitted diseases, accidentally found that the human sperm stored in glass tubes, frozen at -79, -196, and -269,5 ℃ and cold storage at -70 ℃ for 40 days, after thawing there is still Activities of sperm. 1940 Shettles Confirmed Jahnel’s Discovery. And found that dispensing sperm in the capillary by -269,5 ℃ frozen, can still be saved
