Objective To study the general reproductive toxicity of HB13 in SD rats. Methods SD rats, 100 females and 100 males, were divided into low, medium and high dose groups 20, 40 and 80 mg/(kg·d) and the control group (0.5% CMC-Na), The rats were given HB13 for 28 days in male rats and 14 days in female rats respectively before mating, and then mated. The HB13 treatment continued until the 7th day of pregnancy. When the female rats were confirmed pregnant, the male rats were executed and the female rats were executed on the 14th day of pregnancy. Then we can observe the effect of HB13 on fertility and embryonic development in rats. Results Compared with the control group, the body weight of medium, high dose group reduced significantly, the coefficient of testicular and epididymis, abnormal sperm rate increased significantly. High dose group of HB13 also made the fertilityof male rats decline; The body weight, live births uterus weight (including the fetus) of pregnant rats in high and medium group decreased significantly. At the same time, the rate of lost oosperm and absorbed embryo increased. The high dose group of HB13 can also reduce the fertility of female rats. Conclusion The low dose group of HB13 didn't have general reproductive toxicity in rats, the medium dose group impaired early embryonic development, but the high dose group can significantly reduce the fertility of both male and female rats, and can impair the development of embryonic.
