Avian semen cryopreservation: what are the biological challenges?

TLDR
Research based on biochemical and molecular comparisons of sperm among lines may lead to identification of factors that influence the freezability of poultry semen, and susceptibility to the cryogenic process seems to vary among lines and strains of birds.
Evaluation of The Cryopreservation Technology of Poultry Sperm: A Review Study
TLDR
It is concluded from the current review that the cryopreservation technology of poultry sperm is still in a non-advanced stage and needs many new methods to contribute to raising the fertility capacity, vitality and survivability rates after freezing.
Poultry semen cryopreservation technologies
TLDR
This paper reviews the possible reasons for the lower success of poultry sperm cryopreservation and suggests that poultry sperm membranes contain higher quantities of polyunsaturated fatty acids than mammalian sperm, and hence may require more antioxidant protection.
Cryopreservation of rooster sperm.

  • 1993
TLDR
The procedure described is the first to consistently result in > 50% fertilized eggs as a result of conventional intravaginal insemination of sperm processed after thawing by a procedure amenable to the scaleup required for commercial applications.
The effect of sialic acid on the success of poultry spermatozoa cryopreservation
TLDR
The results demonstrate that the optimal SA incubation conditions for improved fertility with frozen/thawed sperm occurs with 160 μg/ mL SA prefreeze for turkey and 120 μg/mL SA pre- freeze for chicken (P<0.05).
Freezing Avian Semen
TLDR
These constraints involve adaptations of the semen media used for freezing and of the zootechnical parameters of semen use, which are highly species-specific.
Evaluation of glycerol removal techniques, cryoprotectants, and insemination methods for cryopreserving rooster sperm with implications of regeneration of breed or line or both.
TLDR
The results indicate that reasonable postthaw sperm quality and fertility can be derived using cryopreserved rooster semen and estimations can be made for storing sufficient material for line or breed, or both, recreation programs.
Cryopreservation of rooster sperm using methyl cellulose.
TLDR
The MC reduces the contraceptive effects of Glycerol when inseminated with fresh sperm, but does not maintain fertilizing capacity in frozen-thawed sperm when used in combination with 3 or 4% glycerol.

Cryopreservation of mammalian sperm: what we ask them to survive.
TLDR
These concepts of membrane structure and the relationship of membrane composition to water and cryoprotectant movement are reviewed and reintroduced in the context of the established and successful protocol for freezing bull sperm to illustrate the molecular responses that may be necessary to survive a freeze-thaw cycle.
The contraceptive action of glycerol in chickens.
Abstract ARTIFICIAL insemination of chickens with liquid semen has been widely practiced for a number of years, but its commercial application has been hindered by the fact that chicken spermatozoa
The history and future of the cryopreservation of avian germ plasm.
TLDR
The history and future of the cryopreservation of avian germ plasm and the definition of “germ plasm” are discussed.
Acrosomal enzymes and ultrastructure of unfrozen and cryotreated human spermatozoa.
TLDR
Cryotreatment severely altered the motility and viability of the spermatozoa and their acrosomal morphology but did not cause significant decreases in most of the acrosome hydrolases measured.
The Fertility of Fowl Spermatozoa in Glycerol Diluents after Intrauterine Insemination
TLDR
A more efficient insemination technique which would increase the fertility of poorly viable sperm samples would be useful since it might render the removal of the glycerol unnecessary.
Effects of glycerol on chicken spermatozoa incubated in vitro at 41 C in oviducal and embryonic cell cultures.
TLDR
The most negative effect of glycerol on semen quality was observed with semen incubated in the tissue culture medium alone, and aspartate aminotransferase activity in the culture fluid revealed a harmful effect on spermatozoa and culture cells.
