The technology that allows us to freeze a stallion’s semen for future use has opened up a world of opportunities. Not only does it allow the stallion’s DNA to be available to mare owners around the globe, but it enables a stallion to stand at stud while he continues his performance career. It also means reduced transport costs and less stress for mares (and their foals-at-foot). And with frozen semen, there is no limit to the length of the transport time, nor any worry about the container arriving at the appropriate time in the mare’s cycle. The use of extenders means that a single ejaculate can be used to inseminate a number of mares. Stallion semen can be collected, and the ejaculate frozen, at any time of year, and straws of frozen semen can be thawed and put to good use within seconds.

Many stallion owners now are looking at freezing semen as genetic "life insurance" for their valuable animals. Should the horse die, or be injured so that breeding is impossible, his frozen store of semen can insure that he can produce offspring for years to come. So far, no one has discovered any limitation on the length of time that semen can remain in the deep freeze. However, the storage temperature must be exceedingly low (i.e., -196� Centigrade)
