The research noted that they don't yet know if this procedure will improve pregnancy rates.

The Journal of Equine Veterinary Science recently published an article titled, "Post-thaw addition of caffeine and/or pentoxifylline affect differently motility of horse and donkey cryopreserved spermatozoa." The authors were Alessandra Rota; Chiara Sabatini; Anna Przyby; Alessia Ciaramelli; Duccio Panzani and Francesco Camillo, researchers and/or practitioners from Italy and Poland.

The summary noted, in part, that, "Caffeine and pentoxifylline added post-thaw were able to increase the proportion of motile spermatozoa only for stallions and not for donkeys. Whether the improvement in post-thaw motility of equine spermatozoa may have an effect on in vivo or in vitro pregnancy rates remains to be determined."
