The decoction did not have the influence regarding to the wet weight of uterus.(2) Wet weight of ovary:Compared with the blank group,the ovary weight of other groups were significantly lighter(p＜0.05).There is two reasons:First, because of decoction intervention ahead of time,it may had the prevention and the treatment dual function;Second,it possibly promoted the ovulation, and caused the liquid discharged from the pouch of the ovary,thus promoted ovary volume and weight decline.(3) Endocrine changes:①The content of androsterone in high dose groups were significantly lower than the low dose groups(p＜0.05),Chinese herbal had certain dose-effect relationship.

上方对于子宫湿重无影响(P＞0.05)。2、卵巢湿重：用药的各组与空白组比较，对于卵巢的重量均有影响(p＜0.05)，考虑有两个原因：第一，由于造模的同时用药，有预防与治疗的双重作用；第二，可能是促进排卵，使囊内卵泡液排出，从而促进卵巢体积及重量的下降。3、内分泌改变：①高剂量组别与低剂量组别比较，在降调总睾酮的作用更大，差异有统计学意义(p＜0.05)，说明中药治疗作用具有一定的量效关系。
