Effects of fluoride and caffeine on the metabolism and motility of ejaculated bovine spermatozoa.


Treatment of washed, ejaculated bovine sperm with 30 mM sodium fluoride immobilized the cells in a characteristically rigid form. In cells metabolizing endogenous substrates, fluoride decreased respiration by about 60%, but did not inhibit the cells' ability to produce adenosine-5'-triphosphate (ATP) via oxidative phosphorylation and did not block access to… (More)
