Fowl sperm are believed to be immotile prior to ejaculation. The concentration of
potassium found in deferent duct fluid is approximately 8 times higher than that found
in blood plasma, which is 5 mM in Gallus domesticus. The effect of ionic potassium
on fowl sperm motion was tested in a...
Sperm mobility denotes the net movement of a sperm population. Previous work implicated mitochondrial function as a basis underlying phenotypic variation in this quantitative trait. Our objective was to determine if mitochondrial function was indeed critical to expression of phenotype. Phenotype was assigned to roosters within a random bred population...
Sperm mobility is defined as the net movement of a sperm population against resistance. Previous research demonstrated that the cell-permeant Ca2+ indicator rhod-2 AM gave a fluorescent signal predominantly in the head region of fowl sperm that differed between sperm mobility phenotypes. This thesis served to explore the role of...
