Fibrinolytic activity of the rat ovum, appearance during tubal passage and disappearance at implantation.
Fertilized rat ova were histochemically examined for their fibrinolytic activity. Activity was found during tubal passage, which disappeared at implantation. Simultaneously the fibrinolytic activity of the endometrium disappeared at deciduation. These changes might be a prerequisite for implantation of the zygote.
