Preservation of boar semen: An update

Reproduction in Domestic Animals, 2019
ContentsIn the pork industry, artificial insemination and the storage of boar semen in liquid at 17°C are routinely applied to optimize the ejaculate and bring about rapid genetic changes that are reflected in the animal protein. Although the results are satisfactory, they are below what occurs with natural mating.

Bacteriology of preserved stallion semen and antibiotics in semen extenders

Theriogenology, 1998
Three experiments were conducted to evaluate the effects of different antibiotics in a milk-glucose semen extender on motility of equine sperm and elimination of bacteria following storage of extended semen in vitro. In Experiment 1, 7 antibiotics were compared: amikacin, gentamicin, streptomycin, potassium penicillin, sodium penicillin, ticarcillin ...

Large-scale preservation of human semen

Cryobiology, 1972
Abstract Data were obtained and analyzed from the freezing of ejaculates of men storing semen prior to vasectomies and for donor insemination. Recoveries comparable to those previously published were obtained. Individual variability in percentage of recovery of sperm was noted but no correlations between the parameters measured and percentage of ...

Cryogenic Preservation of Low-Quality Human Semen

Archives of Andrology, 1990
The article describes the technical strategies for clinical cryogenic preservation of low-quality human semen. To compensate for sperm dilution resulting from the use of a cryogenic medium, ejaculated semen was concentrated before freezing by means of continuous-step density gradient centrifugation.

Insemination with Cryo-Preserved Semen

1982
The concept of cryopreservation of germinal cells is attributed to Spallanzani; Mantegazza was the first to suggest the use of frozen semen banks (Sherman, 1973). The results of attempted cryopreservation of semen have been quite variable and related to the development of the field of cryobiology. The discovery of the superior cryoprotective properties

Control and Preservation of Semen

Proceedings of the British Society of Animal Production, 1946
By control of semen I mean those tests which are applied to a semen sample to determine whether the sample is likely or not to be fertile when used for insemination, and to determine the extent to which it can be successfully diluted. For those who are not familiar with the methods of artificial insemination, I will try to give a very ...

Preservation and evaluation of semen for artificial insemination

Reproduction, Fertility and Development, 2004
Many years of research have been devoted to improving the fertility of preserved semen of small ruminants. There have been few significant advances in preservation in recent times, but considerable knowledge has been gained on the effect of preservation on the structure and function of spermatozoa.

Semen preservation in Macaca fascicularis.

Laboratory animal science, 1979
Semen was collected from adult male Macaca fascicularis using a rectal probe for electro-ejaculation. The effect on sperm motility of varying semen extender egg yolk concentration, pH, glycerol concentration, and equilibration times of sperm with glycerol was examined.

Nephrological Indications for Semen Preservation

1980
Many kidney diseases can strike a man at a time which he desires to be able to procreate. This can lead to sterility in essentially two ways: The inexorable course of many renal disorders towards kidney failure with associated impotence, and the prescription in certain renal diseases of drugs whose adverse effects on spermatogenesis are known.

Artificial Insemination and Semen Preservation

1982
Of the hundreds of millions of sperm cells that leave the male genital tract during intercourse and reach the vagina, only some will be successful enough to reach the female endocervix to be stored there for continuous release. Settlage et al. (1973) and Insler et al.
