Embryonic development in rabbits after insemination with spermatozoa stored at 37, 5 or-196 degrees C for various periods


, : Embryonic development in rabbits after insemination with spermatozoa stored at 37, 5 or-196 degrees C for various periods. Journal of Reproduction and Fertility 48(1): 43-49

Rabbit spermatozoa stored at 37 degrees C for 5 hr, 5 degrees C for 5 hr or 5 days, and-196 degrees C for 5 hr, 5 days, or 1 year were used to artificially inseminate does induced to ovulate normal or excess numbers of eggs. Fertility and subsequent embryonic development were examined. Frozen spermatozoa stored for 5 hr fertilized fewer oocytes than those stored for 5 days or longer. Fewer embryos were recovered on Day 6 than on Day 2. Blastocysts were smaller when spermatozoa were stored for 5 days, were frozen or were placed in superovulating does, but no statistically significant differences in the % of fetal survival were found in the groups of normally ovulating does. Embryonic wastage associated with storage of spermatozoa resulted from a reduced fertilization rate and/or increased embryonic mortality before implantation.
