The components of ruminant seminal plasma and their influence on the fertility of spermatozoa are reviewed. Seminal plasma can both inhibit and stimulate sperm function and fertility through the multifunctional actions of organic and inorganic compon

Contents Successful sex-sorting of goat spermatozoa and subsequent birth of pre-sexed kids have yet to be reported. As such, a series of experiments were conducted to develop protocols for sperm-sorting (using a modified flow cytometer, MoFlo SX®) a

In order to advance the development of cryopreservation and other assisted reproductive technologies in camelids it is necessary to eliminate the viscous component of the seminal plasma without impairing sperm function. It has been postulated that gl

Cryopreserved, sex-sorted stallion sperm has been shown to have poor fertility. During this study, the effects of cryoprotectant (glycerol [GLY] and dimethyl formamide [DMF]), cryoprotectant equilibration time (0, 30, 60, 90, or 120 minutes), and cry

Excessive reactive oxygen species generation during sex sorting and cryopreservation of stallion sperm leads to DNA fragmentation, lipid peroxidation, and motility loss. In this study we investigated whether antioxidant supplementation during sex sor

Camelid semen is characterized by a highly viscous, low-volume ejaculate with a low concentration of spermatozoa that exhibit low progressive motility. The viscous seminal plasma is currently the major impediment to the development of assisted reprod

Sex-sorted, frozen-thawed stallion spermatozoa remain out of reach of commercial horse breeders because of the low efficiency of the sex-sorting process and unacceptable fertility rates after insemination. Two experiments were designed to test the ef

The low efficiency of flow cytometric sex-sorting of stallion sperm has been attributed to the use of an opaque skim milk-based diluent during Hoechst 33342 (H33342) staining. Three experiments were conducted to formulate an optically clear stallion

The response of ram spermatozoa to seminal plasma is highly variable, in part due to the presence of both stimulatory and inhibitory factors. The aim of this study was to assess variation in the protection of ram spermatozoa during freezing by semina

Despite considerable cryobiology research there is no industry standard for the concentration to which ram spermatozoa should be diluted before freezing. Ram semen is highly concentrated and often frozen at a high sperm concentration, necessitating t
