title: [Maturation and fertilization of human ova outside of the body].
abstract: The egg-cells were obtained from ovaries removed for different clinical reasons and cultivated after Edward's technique with modifications to complete the maturation division. The process of fecundation, formation of pronucleuses, separation of the 2nd pole body and the first stage of egg-cell cleavage (up to the stage of 3 blastomeres). Non-fertilized egg-cells underwent random fragmentation into blastomere-like nucleus-free particles.
