The changing trend of progesterone during oestrous cycle resembles with that during the first 14d of early pregnancy. Its content reaches the peak value at lOd after oestrus and then declines. The estradiol peak appears at 3d of oestrous cycle, and the level rises again before oestrus. The concentration of LH declines after oestrus. The level of follicle stimulating hormone reaches the peak value at lOd after oestrus (2.40mIU/ml).

He experiment proved that pre-implantation embryos are more sensitive than post-implantation ones, suggested TCDD may exert its effect before implantation, or at this process. 3. The toxicity of TCDD on the early embryo can be of omnifarious. It can strongly inhibit DCR, which represent mother toxicity; It cause un-synchronizated cleavage of pre-implanted zygote and pre-implanted embryo loss; It also decreases implantation sites in the uterus, and continued to effecting the uterus of pregnant mouse, cause the decreased number of fetus before birth. 4. TCDD exposure changed reproductive hormone level of pregnant mouse.

CDD对胚胎的毒性影响可能是多方面的：强烈抑制子宫蜕膜细胞反应，表现出典型的母体毒性；虽然没有影响胚胎转运速度，但造成着床前胚胎的丢失和发育不同步；早期染毒降低了第9天的胚胎着床数，同时使出生前第18天胚胎成活数继续减少。
