Resumen:
The ability of a range of extenders to cryopreserve ram spermatozoa was tested. The extenders were modiWed by the
inclusion of citrate, Tris buVer, trehalose, and EDTA. Ejaculates from three Pampinta rams were evaluated and pooled
at 30 °C. The semen was diluted to contain 1£109 cells/mL, cooled to 5 °C, loaded into 0.25-mL straws, frozen and
stored in liquid nitrogen. Evaluation was based on the hypoosmotic swelling test (HOS test), electron microscopy, and
biochemical parameters such as lipid peroxidation and reduced and total glutathione levels, all measured after thawing.
The HOS test indicated that the percentage of intact plasma membranes after freezing and thawing was signiWcantly
higher for the hypertonic extender containing trehalose (T), compared with an extender containing trehalose+EDTA
(TE) or an isotonic Tris extender (B) (p < 0.05). Membrane evaluation by ultramicroscopy also indicated better sperm
cryopreservation in extender T compared with the others, and there was a signiWcant reduction in the number of damaged
membranes (27%, p < 0.0002). The level of reduced glutathione was signiWcantly higher after sperm cryopreservation
in either hypertonic diluent (T and TE) with respect to the isotonic extender B, immediately after thawing (12%)
and after a 3-h post-thawing thermotolerance test at 37 °C (17%, pD0.007). Total glutathione levels did not show statistical
diVerences among the extenders. After 3 h post-thawing incubation at 37 °C, lipid peroxide levels in spermatozoa
were statistically lower for T than TE (35%) or isotonic extender B (44%) (pD0.002). Taken together these results indicate
a reduction in the oxidative stress provoked by freezing and thawing when semen is cryopreserved in extender T.

cryopreservation in extender T compared with the others, and there was a signiWcant reduction in the number of damaged
membranes (27%, p < 0.0002). The level of reduced glutathione was signiWcantly higher after sperm cryopreservation
in either hypertonic diluent (T and TE) with respect to the isotonic extender B, immediately after thawing (12%)
and after a 3-h post-thawing thermotolerance test at 37 °C (17%, pD0.007). Total glutathione levels did not show statistical
diVerences among the extenders. After 3 h post-thawing incubation at 37 °C, lipid peroxide levels in spermatozoa
were statistically lower for T than TE (35%) or isotonic extender B (44%) (pD0.002). Taken together these results indicate
a reduction in the oxidative stress provoked by freezing and thawing when semen is cryopreserved in extender T.
