The Decidual Hormones and Their Role in Pregnancy Recognition
How does the mother recognize the presence of the blastocyst and adjust to provide the right milieu for the embryo to implant, to grow, and to remain in a safe uterine environment until able to survive outside the womb? The answer to this question, as discussed by Dr. Mori and Kanzaki in another chapter, appears to differ in different species. However one common denominator to all species is the necessity to maintain adequate levels of ovarian steroids in the maternal circulation and to rapidly change the uterine environment so that contact between mother and fetus becomes possible without damage to the mother or rejection of the fetus.
