During the last half of the 20th century there have been considerable advancements in
mammalian reproductive technologies, including in vitro production of pre-implantation …

Contents Storage of buffalo (Bubalus bubalis) bull semen in the cryopreserved state is
discussed in this article. Fertility rate in buffalo following artificial insemination with frozen …

Germplasm storage and transportation in artificial insemination (AI) and other advanced
technologies are facilitated by cryopreservation. In reproduction, the cryopreservation of …

Geographical barriers to breeding animals have long been reduced because of possibilities
of semen transportation. In modern cattle breeding, where artificial insemination (AI) is the …

Cryodamage is a major problem in semen cryopreservation, causing changes in the levels
of proteins that influence the function and motility of spermatozoa. In this study, protein …

Acceptable fertility using cryopreserved ram sperm is currently only achieved using
laparoscopic intrauterine insemination. Improving the cryosurvival of ram sperm may permit …

Contents Artificial insemination in ram is scarcely widespread comparing with other
domestic species. This has been due not only to fertility results being irregular and low but …

Abstract Currently, more than 16,000 plant and animal species are imminently threatened by
extinction, often as a direct consequence of anthropogenic influences. One of the measures …

Damage occurring to spermatozoa during cryopreservation results in a loss of motile cells
and cells that are functionally normal, compared with fresh sperm samples. Treating bull …

Ram semen contains sufficient quantities of superoxide dismutase (SOD) and much lower
concentrations of glutathione peroxidase (GSH-PX) and catalase (CAT) to prevent oxidative …
