The presence of an uneven distribution of unruptured follicles between "left and right ovaries" by ultrasound is a normal finding, as there is no symmetry in ovulation, with only the most mature eggs "chosen" by stimulation from pituitary hormones from the ovaries, and one ovary may predominate, causing apparent asymmetry.
