2021
Mrackova, Miroslava | Vojtechovska, Lenka | Andrlova, Petra et al.
Two substances at two concentrations each were added to frozen-thawed stallion epididymal spermatozoa to improve motility indicators, which were assessed 30, 60, 120, 180 and 240 min after thawing. Pentoxifylline was added at concentrations of 3.6 mM (1 mg/ml) and 7.18 mM (2 mg/ml). Both concentrations had a positive effect on total and progressive motility of spermatozoa throughout the study. The other substance, caffeine, was added at concentrations of 2 mM (0.4 mg/ml) and 5.5 mM (1 mg/ml). Both concentrations had a positive effect on total and progressive motility of spermatozoa only 30 and 60 min after thawing. Subsequently, 180 min after thawing, improvement was found only in total sperm motility.
