title: [Implantation of the zygote].
abstract: In order for implantation to occur, the endometrium must be adequately differentiated, a estate which results from the sequential interaction of progesterone and estrogens, and the local effects of prostaglandins and histamine. Nevertheless, the exact mechanism through which these hormones affect the uterus is not clearly understood. Recently it has been proposed the role of second messengers (cAMP.cGMP, inositol triphosphate and diacylglycerol) in this process. All these messengers are related with the intracellular mechanisms of proteic and steroid hormones action.
