Abstract: The invention relates to compositions for in vitro fertilization, or for the in vitro culture of follicles, male germinal cells or embryos, said compositions comprising at least two growth factors in association with a compound of the family of corticoids involved in energetic production in mammals. The invention also relates to the culture media obtained with these compositions, these latter being preferably in the form of a lyophilizate. The invention also has for its object processes for the in vitro fertilization and processes for maturation of follicles, of male germinal cells, or embryos using such culture media, as well as kits for the practice of these processes and comprising a lyophilizate as mentioned above and an aqueous solution, if desired commercial, containing other constituents of said culture medium.
