Follicle density by diagnosis, comparing benign lesions. Women with endometriosis involving the ovary had the highest number of follicles per section while women with cystadenomas had the fewest follicles per section. There was a trend seen in patients with benign lesions having decreased follicular density, but this did not reach statistical significance. With benign ovarian lesions, there may be a proliferation of ovarian stroma, with the same number of follicles spread over a larger surface area.
