What is it about?
A remarkable feature of the female reproductive tract in many mammals, birds, fishes and reptiles is its ability to keep sperm alive for long periods, ranging from a few days to a few years. How this is achieved has remained a mystery despite several decades of research. Here we review what is currently know about the mechanisms responsible for sperm storage in an effort to identify clues that might be useful for the development of methods for artificial insemination.

Why is it important?
If we could understand the physiology behind long-term sperm storage it would help with the development of long-term sperm storage methods for use in animal breeding and human clinical medicine. At present, the only way to store sperm outside the body for more than a few days is to use freezing techniques. These cause considerable damage to sperm from most species, and significantly reduce the longevity of those that survive.
