Abstract: An embryo culturing method and apparatus enables a plurality of embryos to be grown in communal clusters in a culturing container. The embryos are kept separate from each other in open interconnected compartments that are disposed in the culture container. Each compartment is contained in a structure having a plurality of interconnected compartments, and each compartment is sized to contain a single embryo. The culturing container will contain a plurality of the compartmentalized structures. The method and apparatus of this invention includes a culturing container, such as a Petrie dish, in which the embryos are grown. The Petrie dish preferably contains a plurality of the embryo-culturing compartmentalized structures which can be positioned in the Petrie dish in a predetermined pattern. For example, the compartmentalized structuress can be positioned in the Petrie dish at the 12 O'Clock, 2 O'Clock, 4 O'Clock, 8 O'Clock and 10 O'clock positions, or in any other planned deployment.
