Coral Species Cryopreserved with Global Collaborators​

Mary Hagedorn, Ph.D., and her team developed a low-cost technique for cryopreserving coral sperm cells and have shared this knowledge with coral researchers around the world. Coral genetic material frozen in this way can be viable for hundreds of years. Conservationists can use the frozen sperm to generate new corals and to strengthen small populations by adding genetic diversity.

Below is a comprehensive list of all the coral species that have had sperm cells cryopreserved (as of December 2021) — an impressive result of international collaboration.

*There is some overlap in cryopreserved species across regions. ​They are counted twice in this list because if they are not separate species,​ they are distinct populations.
