The nature and distribution of smooth muscle cells in the ovaries of the cat, rabbit, and human being were investigated by both histochemical and electron microscopic studies. In the human ovary, the typical smooth muscle cells are abundant in both the theca externa of the follicle and the cortical stroma. In the rabbit ovary, smooth muscle cells are concentrated in the cortical stroma rather than in the follicle wall. In the cat ovary, the smooth muscle cells cannot be considered typical. The characteristic features of these cells are discussed, and the possible role of ovarian smooth muscle in the ovulatory mechanism is suggested.
