Abstract Objective To learn the effects of Dendrobium officinale flowers on testivular tissue morphology and sperm quality in parent and offspring rats,so as to provide reference for safety evaluation of Dendrobium officinale flowers. Methods The 40 SD rats was randomly divided into the low-,middle-,high-dose and the control group,given 2.0,4.0,6.4 and 0 g/kgbw Dendrobium officinale flowers,respectively. After three months,the body weight,mass and organ/body coefficients of testis and epididymis of parent （P） and offspring （F1,F2） rats were measured;the number,activity and deformity of sperms were observed under microscope;the changes of testis and epididymis were observed by hematoxylin eosin staining. Results There were no significantly statistical differences in the body weight,mass and organ/body coefficients of testis and epididymis,sperm quantity,sperm motility rate among four groups of P、F1、F2 male rats （P>0.05）. There were no significantly statistical differences in sperm malformation rate between the high-dose group and the control group （P>0.05）. There was no significant change in testis and epididymis of P,F1 and F2 male rats. Conclusion Dendrobium officinale flowers did not show obviously adverse effects on testivular tissue morphology and sperm quality in parent and offsping rats.
