title: Effect of Ferula assa-foetida oleo gum resin on spermatic parameters and testicular histopathology in male wistar rats.
abstract: BACKGROUND
  In Ayurveda and traditional medicines of different countries such as Iran, America and Brazil, asafoetida has been used as an aphrodisiac agent.
  
  
  OBJECTIVE
  The present study was aimed to evaluate the effectiveness of asafoetida on spermatic and testicular parameters in treated rats.
  
  
  METHODS
  A total of 30 male Wistar rats divided equally to five groups (one control and four test groups receiving 25, 50,100 and 200 mg/kg asafoetida respectively). After 6 weeks, a small part of the cauda epididymis of each rat was dissected, and the spermatic parameters were evaluated for at least 200 spermatozoa of each animal. Testis of all rats was harvested for pathologic examination. The testosterone concentration of serum was also determined. Data were statistically assessed by one-way ANOVA and value of P < 0.05 was considered as the level of significance.
  
  
  RESULTS
  This study indicated that the asafoetida significantly increased the number and viability of sperms (P < 0.05). Histological study showed that spermatogenesis process and numbers of Leydig cells were increased with increasing the dose, but the Leydig cells become vacuolated. Johnsen score in experimental groups was increased compared to control although this difference was not significant (P > 0.05).
  
  
  CONCLUSIONS
  Asafoetida showed a positive effect on spermatic parameters although the histopathological effects on the testis were observed, particularly at high doses.
