Scientists getting closer to understanding mechanisms that influence pregnancy success
In the early stage of pregnancy, the dialogue between the developing embryo and the mother is one of the key factors determining the success of the embryo implantation process in the uterus. Scientists from the Institute of Animal Reproduction and Food Research of the Polish Academy of Sciences in Olsztyn have discovered another relationship that helps to understand this complicated process.
