The effects of local and sustained release of fibroblast growth factor on testicular blood flow and morphology in spermatic artery--and vein-ligated rats.

Background/purpose: This study was carried out to evaluate the effects of local and sustained release of fibroblast growth factor (FGF) on testicular blood flow and morphology in spermatic artery--and vein-ligated rats.

Methods: Forty male Wistar albino rats weighting 300 +/- 20 g were allocated randomly into 5 groups consisting of 8 in each as follows: G-S (sham); G-C (control); and G-T0.85, G-T1.
