The adjectives oval, ovate, and ovoid all come from roots meaning "egg-shaped". They are usually denotatively synonymous. A connotation of one end being bigger than the other (which is often true of eggs) may or may not be implied. Of the three, oval is the one mostly likely to connote a symmetrical ellipse.
