Abstract

Thirty pairs ovaries of camel from Isfahan abattoiry were collected. In each specimen,  some parameters such as  length, width and thickness of left and right ovaries were measured. For histological studies , after tissue preparation  and staining with H&E, the ovarian follicles were recognized and classified. For each follicle some parameters such as: diameter of oocyte and follicle, thickness of layers were measured .At result, data between left and right ovary were analysed and were compare by t-test. The results showing that, mean length(37.19 ±3.45mm), width(30.12± 2.52mm) and thickness(19.04 ±2.03) in right ovary was more than mean length(33.57 ±3.44), width(27.41± 2.62) and thickness(15.5 ±1.97) in left ovary. There was no significant difference between dimensions of left and right ovaries. Microscopical studies revealed that, there was also no significant difference in diameter of primordial and primary follicles  and its oocyte of left and right ovaries. However , the diameters of secondary follicle and its oocyte in right ovary (2546.75± 93.75 µm) was more than left(2135.25 ±63 µm). There was significantly difference between diameter of scondary follicles in left and right ovaries. In graafian follicles, no significant difference detected between the right and left ovaries.There was no significant difference between dimensions of left and right ovaries in camel. Also diameter of  secondary follicle  and its oocyte  in right ovary were more than left.
