Genetic preservation of a stallion’s DNA is possible after castration or untimely death. A procedure referred to as epididymal s***m harvest can be performed to remove s***m from the tail of the epididymis after the te**es have been removed. The epididymis is the storage facility of the te**is and the tail of the epididymis stores billions of s***m. This organ can be dissected away from the te**is and flushed with semen extender. The s***m recovered can be frozen conventionally and stored in liquid nitrogen. S***m frozen after epididymal s***m harvest has been utilized to breed mares and obtain pregnancies. This technique allows us to preserve a stallion’s genetics after castration or death for many years.
