[Successful use of deep-frozen stallion sperm after 23 years of storage at -196 degrees C].
A reduction in the motility of the spermatozoa in stallion semen stored in pellet form for 23 years in liquid nitrogen at -196 degrees C could not be seen after thawing. The insemination of a mare with this semen resulted in a normal pregnancy. A normally developed, healthy male foal was born after a gestational period of 321 days.
