title: Sperm motility stimulation and preservation with various concentrations of follicular fluid.
abstract: OBJECTIVE
  The purpose of this study is to evaluate the optimal concentrations of follicular fluid (FF) for sperm motility stimulation and preservation.
  
  
  METHODS
  Thirty normal semen samples and FF from women in an in vitro fertilization programme were used in an experiment. The semen was processed and incubated in Earle culture media with 20, 50, 80, and 100% FF (v/v) with controls. Sperm motility was evaluated and followed up for 48 h.
  
  
  RESULTS
  FF could stimulate progressive sperm motility at all concentrations and last for at least 12 h. However, at more than 50% v/v of FF, sperm demonstrated a rapid decline in progressive motility after 12 h of incubation compared to other concentrations and the control group.
  
  
  CONCLUSIONS
  FF can stimulate the sperm motility properly at not more than 50% (v/v) concentration.
