The three different examples of stromal/total area ratio in pathological and normal ovaries. (A) Polycystic ovary. (B) Multifollicular ovary. (C) Normal ovary. All figures were obtained with a transvaginal approach. The values on the left side represent the circumference of the ovary and of the stroma; those on the right represent the total area of the ovary and the area of the stroma.
