Fig. 3From: In vivo bioactivity-guided isolation of antifertility fraction of Waltheria indica Linn. root in male Wistar ratsPhotomicrographs of the testis of male Wistar rats exposed to different doses of hexane soluble fraction of WILR. Control (C): normal testis showing the seminiferous tubules (star) and interstitium (black arrow). 200 μg/kg (HA): loss of interstitium (arrow) and germ cells. 500 μg/kg (HB): loss of interstitium (arrow) and erosion of germinal epithelium. 1000 μg/kg (HC): loss of interstitium (black arrow).
