This study was conducted to investigate the effects of Epimedium polysaccharide (EPS) on ovarian and uterine development in female mice and assess the in vitro maturation (IVM) rate. Healthy Kunming female mice were divided into 4 groups and administered 2, 4, 6, and 8 mg/0.1 mL of EPS, respectively; the control group was given 0.1 mL of 0.9% physiological saline solution. After 7 and 14 days, the mice were sacrificed and their reproductive tracts (uterus, oviduct, and ovaries) were removed. The reproductive tract was weighed; some ovaries were punctured to harvest oocytes for IVM culture and the others were used for histological analysis. EPS had virtually no effect on the body weight of the female mice. EPS at 4 mg/0.1 mL for 14 days of treatment had a significant effect (P < 0.05) on ovarian and uterine development when compared with 2, 6, and 8 mg/mL but no significant effect (P > 0.05) when compared with the control group. The number of follicles increased in the experimental groups and the arrangements of ovarian follicles were not negatively affected during histological observation. In conclusion, EPS at appreciable dosages has a positive effect on mouse ovarian development.
