[The relationship between the implantation of ovarian stimulated embryos and the expression of leukemia inhibitory factor mRNA in mice metrium].

Objective: To check the expression of leukemia inhibitory factor (Lif) mRNA, and to study the impact of ovarian stimulation on the ability of embryo implantation in mice.

Methods: Pregnancy models of mice were established. The relationship between the implantation of ovarian stimulated embryos and the expression of Lif mRNA in mice metrium was analyzed.
