title: A comparative study of buffer systems as cryoprotectants for human spermatozoa.
abstract: Several cryoprotective media currently in use for human sperm cryopreservation have been directly compared with each other by use of a static vapor freezing technique. The TEST-citrate-yolk buffers with glycerol resulted in the highest motility and longevity after thawing; thus, their use is recommended.
