title: [Influence of dibutyryl cyclic adenosine monophosphate on motility of sperm].
abstract: OBJECTIVE
  To investigate the influence of cAMP/PKA signal transduction on human sperm motility, and to study the effect of dibutyryl cyclic adenosine monophosphate dibutyryl cyclic adenosine monophosphate (dbcAMP) on human sperm motility in vitro.
  
  
  METHODS
  Sperm aseptically obtained by masturbation and prepared by swim-up technique from 10 healthy fertile men were incubated with different concentrations of dbcAMP. Measurement of mobility were carried out at 20, 30, and 60 min in all specimens.
  
  
  RESULTS
  The sperm treated with dbcAMP showed a significant increase in sperm progressive motility and the percentage of motile cells. The effect seemed enhanced with the increasing of dbcAMP concentration. VSL and VCL were not affected by dbcAMP.
  
  
  CONCLUSIONS
  dbcAMP can activate the mobility of human sperm in vitro.
