Dr. Yoon Tae-gi and his colleagues discover a revolutionary new way to store sperms
- The discover is published on April issue of Fertility and Sterility Online.
- The new method solves the contagion problem when the sperms are stored

Dr. Yoon Tae-gi and his team of researchers at CHA Fertility Institute propose a new method to freeze-store the sperm; and Reuter Health presents full coverage of the finding.
Dr. Yoon and his team innovates the liquid nitrogen freeze-storing method for sperms. Conventionally, sperms were immersed in liquid nitrogen at 196 degrees Celcius, a temperature at which the sperm can remain frozen; however, there was a problem with this method? the sperms were exposed to infection from the virus or bacteria if the liquid nitrogen was contaminated. Dr. Yoon and his team revised the method and stored the sperms in the steam that existed in the tank of liquid nitrogen, reducing the contagion to the sperms while maintaining the survivability of the sperms. The sperm mitochondria, vitality, and activity remained almost unchanged from the sperms before they were frozen. This finding was published in Fertility and Sterility Online last April.
Reuter reports Dr. Yoon's method a safe alternative for sperm storage. According to Reuter Health, Dr. Yoon's method suggests a new approach to storing the sperms, and that it is the only existing method to keep the sperm's biological properties after a freeze-thaw cycle. Dr. Yoon's and his team plan to proceed with the study and use the sperms for the conception of a test tube baby.
