Cryopreservation of Rooster Sperm

Poultry Science, 1993
Successful cryopreservation of sperm requires: 1) selection of proper diluent; 2) selection of the best cryoprotectant; 3) determination of freezing and thawing rates for optimum retention of fertilization potential; and 4) removal of any materials deleterious to fertility (e.g., glycerol) before insemination.

Computerized Sperm Motility and Application of Sperm Cryopreservation [PDF]

Archives of Andrology, 1988
An objective method for measuring sperm motion characteristics was developed on an Intellect 100 Quantel Image Analysis System suitable for various image cytometric applications. It provided overall analysis of percent motility (% MS) as well as individual and mean measurements of motion characteristics, including vigor characteristics such as ...

Cryopreservation Effects on Ram Sperm Ultrastructure [PDF]

Biopreservation and Biobanking, 2020
Cryoprotectants are known to have protective effects against cryodamage to spermatozoa. In this study, the cryoprotective effects of two cryoprotectants (glycerol, ethylene glycol) and cryoprotectants/trehalose combinations on frozen-thawed ram spermatozoa were investigated at the ultrastructural level. For this purpose, ejaculates

A review on the functional roles of trehalose during cryopreservation of small ruminant semen

Frontiers in Veterinary Science
Sperm cryopreservation is an approach to preserve sperm cells in liquid nitrogen or other cryogenic media for future use in assisted reproductive technologies, such as in vitro fertilization or artificial insemination.

The use of deidentified organ donor testes for research

Andrology, EarlyView.
Abstract Our knowledge of testis development and function mainly comes from research using mammalian model organisms, primarily the mouse. However, there are integral differences between men and other mammalian species regarding cellular composition and expression profiles during fetal and post‐natal testis development and in the mature testis ...

A novel approach to sperm cryopreservation [PDF]

Human Reproduction, 1999
Human spermatozoa have unusual cryobiological behaviour and improvements in their survival have not been achieved by the standard approaches of cryobiology. Conventional approaches to cryopreservation impose a linear change of temperature with time; however, the stresses that cells encounter during cryopreservation are all non-linear with time. In this

EFFECT OF DIFFERENT CRYOPROTECTIVE AGENTS ON SKIM MILK AND DIMITROPOULUS EXTENDER FOR STALLION SEMEN CRYOPRESERVATION [PDF]

, 2010
Cryoprotective agents (CPAs) protect sperm during cryopreservation. The objective of this study was to assess different CPAs on stallion semen cryopreservation. Skim milk (SM) and Dimitropoulos (DV) were the extenders used in this study; each was added

Best practices for cryopreserving sperm in Nonhuman Primates: a systematic review and meta-analysis

Scientific Reports
Nonhuman primates (NHPs) are in increasing demand as models for preclinical research. The availability of a highly efficient cryopreservation protocol for use with NHP sperm has potential to significantly alleviate this demand and contribute to rapid ...
