Rabbit Sperm Cryopreservation

Sperm cryopreservation is an excellent way to store genetic materials for a long period. Semen cryopreservation is associated with structural and functional damage of the spermatozoa caused by cold shock, osmotic stress, intracellular ice crystal formation, and the production of reactive oxygen species, which reduce their functional lifespan and ...

Cryopreservation of epididymal stallion sperm

Cryobiology, 2014
Any event that makes semen collection or mating impossible, such as death, castration, or injury, may terminate a stallion's breeding career. Fortunately, stallion sperm which are capable of fertilization can be harvested from the epididymis, and frozen for future use.

Cryopreservation of Plagiognathops microlepis sperm

Cryobiology, 2018
Sperm was collected from cultured male fish and cryopreserved in 0.25 ml straws for the study of sperm cryopreservation. Different parameters were evaluated, including extender, dilution ratio, cryoprotectant type and concentration, equilibrium time, cooling height (in a two-step cooling protocol), and thawing temperature.

Cryopreservation of epididymal dog sperm

Animal Reproduction Science, 2001
A method of cryopreservation was developed for sperm salvaged from the cauda epididymis and vas deferens of domestic dog testes. Four modifications of the glycerol concentration of a buffer used for cryopreservation of dog ejaculates and two freezing rates were assessed for their effect upon post-thaw spermatozoal motility and morphology.

Cryopreservation of microencapsulated canine sperm

Theriogenology, 2011
The objective was to develop a method for cryopreserving microencapsulated canine sperm. Pooled ejaculates from three beagle dogs were extended in egg yolk tris extender and encapsulated using alginate and poly-L-lysine at room temperature. The microcapsules were cooled at 4 °C, immersed in pre-cooled extender (equivalent in volume to the microcapsules)

A new development in the cryopreservation of sperm

Human Fertility, 2002
Recent developments in in vitro fertilization have made it necessary to develop better methods for sperm cryopreservation. This article sets out the cryobiological and physical background relevant to sperm cryopreservation together with some new observations on the morphology of sperm in the frozen state.

Sperm Cryopreservation and In Vitro Fertilization

2009
Since the mouse has become the most profound model system to investigate the genetics and pathogenetics of human diseases, a huge number of new mutant mouse strains has been generated and still a lot effort is being done to increase the number of suitable mouse models.
