The study conducted on the Iraqi buffalo ovaries in esterous stage at sixth to ninth years old . The study was appeared the buffaloes ovary enclosed by delicate fibrous capsule , the mean thickness in right and left ovary ( 37.5 ± 0.14 , 25± 1.52 , 18.75 ± 0.12, 17.22± 0.51) at respectively . The ovarian capsule enclosed by simple cuboidal epithelium . The study was revealed the buffalo ovary composed of ovarian cortex and medulla . the cortex was occupied large region when compared with medulla , the mean thickness of cortex in the left and right ovary of the study groups was (5625± 5.28 , 4357 ± 2.5 , 4102 ± 2.62 , 4010± 3.84 ) micrometer at respectively , while the mean thickness of the medulla was( 2875 ± 1.82 , 2375±2.24, 2235± 1.72 2125± 3.95 ) micro meter at respectively in left and right ovary of different age . The cortex of the buffalo ovary was included three types of ovarian follicles, primary , secondary and Graffian follicles which pass in different stages of development . the diameter of graffian follicles in nine year s old more when compared with sex years old in each right and left ovary ( 498±3.22, 425 ±2.86, 383± 1.14 , 397± 4.81 ) micro meter at respectively . The medulla of ovarian buffalo was characterized by very rich blood vessels supply consist of arteries , veins and their branches and nerves , as well as study was recorded the differences in the mean diameters of blood vessels that nourished the ovarian medulla.
