Abstract: Maternal-fetal dialogue is a complex dialogue between mother and fetus during pregnancy, which is a necessary process for successful implantation and pregnancy and is regulated by many factors. Abnormal mother-fetus dialogue can lead to the failure of embryo implantation and pregnancy, and can affect the normal development of fetus during pregnancy. Therefore, mother-fetus dialogue during pregnancy is of great significance for improving the litter size and reproductive efficiency of pigs. The review summarized the factors influencing the mother-fetus dialogue from pregnancy recognition (before pregnancy), embryo implantation (pregnancy) to fetal development (after pregnancy) using sows as a model, including hormones, cytokines, adhesion factors, genes and proteins, etc, which can provide reference for pig maternal-fetal dialogue study and increasing litter size in pig industry.

Key words: maternal-fetal dialogue, sow, pregnancy recognition, embryo implantation
