Adenine nucleotides and other factors indicative of glycolytic metabolism in murine spermatozoa.

Cyclic adenosine 3':5' monophosphate (cAMP) accumulation during one hour's incubation in 10 mM theophylline and 10 mM pyruvate; initial concentrations of adenosine triphosphate (ATP) and their rate of depletion during one hour's incubation; concentrations of adenosine diphosphate (ADP), adenosine monophosphate (AMP), fructose 2,6 diphosphate (FDP), and glyceraldehyde 3-phosphate (GAP), were assayed in spermatozoa of various genotypes. No effects of transmission ratio distorting t-haplotypes (in heterozygous males) on these variables were found.
