The ovaries in the female are said to be the analogues of the testicles in the male; they both secrete a fluid that is essential to impregnation. They are situated on either side of the uterus, and are attached to either side of it by the posterior duplicature of the broad ligament called the ligament of the ovary. (Fig. 12).

They are oval flattened bodies about an inch and a half long, three-quarters of an inch wide at their greatest breadth, and a quarter of a inch thick. They are situated on the sides of the uterus in that portion of the broad ligament called the posterior wing, just behind the Fallopian tubes. The ovary consists of a peculiar structure enclosed by two envelopes, one of which is serous and the other fibrous. Within the fibrous coat is a special tissue called the stroma; imbedded in this are numerous small round transparent vesicles in various stages of development, varying in size from that of a millet seed to that of a hemp seed. They are the ovisacs, containing the ova, and are called the Graafian vesicles. These have thin transparent walls and contain a clear fluid, and within that the ovula. Fifteen or twenty may readily be distinguished in the adult female without the aid of magnifying glasses.
