GROWTH FACTORS IN THE FOLLICULAR DEVELOPMENT, EMBRYONIC EARLY AND IMPLANTATION. IMPLICATIONS IN THE PRODUCTION OF BOVINE EMBRYOS

The review describes the role the growth factors on follicular development, early embryonic, implantation and their importance in the production of bovine embryos. It describes, growth factors its important roles in key events of the reproductive activity, although some mechanisms action and their synergistic effects with other hormones are well known, their full role is far from being elucidated. Previous works in vivo and in vitro studies point out that they could improve notably, fertilization and clivage rates and implantation.
