A trio of researchers with the University of Lausanne has found that cryopreservation of fish sperm leads to slowed growth of their offspring. In their paper published in Proceedings of the Royal Society B, David Nusbaumer, ...
Cryopreservation is a process where cells or whole tissues are preserved by cooling to low sub-zero temperatures, such as (typically) 77 K or −196 °C (the boiling point of liquid nitrogen). At these low temperatures, any biological activity, including the biochemical reactions that would lead to cell death, is effectively stopped. However, when cryoprotectant solutions are not used, the cells being preserved are often damaged due to freezing during the approach to low temperatures or warming to room temperature.
