title: Triple-blind, placebo-controlled trial of Ginkgo biloba extract on sexual desire in postmenopausal women in Tehran.
abstract: BACKGROUND
  During the menopausal period, sexual desire may decrease. Therefore, restoring the sexual desire may help to improve sexual functioning in this group of women. The aim of this study was to examine the effect of Ginkgo biloba extract (GBE) on sexual desire in postmenopausal women.
  
  
  METHODS
  In this triple-blind, randomized, placebo-controlled trial, 80 healthy female volunteers attending three healthcare centers of Tehran University of Medical Sciences (TUMS) were enrolled. The instrument of this study had two main parts. The first part covered the personal characteristics of the volunteers and the second part used the Sabbatsberg Sexual Rating Scale (SSRS) to subjectively evaluate sexual desire before and after intervention. The participants received GBE at a dose of 120-240 mg (n = 40) or received placebo (n = 40) daily for 30 days. The results were analyzed using Mann-Whitney test. All analyses were performed using SPSS software.
  
  
  RESULTS
  The sexual desire was significantly improved in the GBE group compared to the placebo group (P = 0.02).
  
  
  CONCLUSIONS
  In this study, we found that GBE had a positive effect on sexual desire of menopausal women; thus, these findings support the positive effect of GBE on the sexual function of menopausal women.
