Fig. 2From: Effect of a bradykinin potentiating factor separated from honey bee venom on thyroid gland and testis in hypothyroid white ratsa, c, d Photomicrograph of testes is showing normal seminiferous tubules with different stages of spermatogenic cells. Also, the lumen of seminiferous tubules was fully packed with sperms (stars). b Photomicrograph of hypothyroid testes showing marked morphological changes as degeneration of germinal epithelium and sloughing of germ cells into the tubular lumen (arrow) compared to control. e, f Photomicrograph of hypothyroid rat testes co-administrated with BPF and levothyroxine showing normal spermatogenic cells and increase of sperms (star) similar to those treated with either BPF (c) or levothyroxine (d) only as compared to hypothyroid animals.
