Sperm freezing is a method of preserving a man’s fertility, so he may try to have children at a later stage in life. A special media (cryoprotectant) is first added to the sperm.
Once the media has been incorporated into the sperm, the sperm together with the media is loaded into either cryo-vails or cryo-straws and placed in liquid nitrogen at -196°.
At this temperature, sperm can be stored for many years while maintaining a reasonable quality.
Why should you freeze sperm?
