The main objective of the present study was to investigate the changes in ovarian oestradiol and testosterone concentrations as follicles develop in the camel. Ovaries were collected from 15 non-pregnant females from a slaughter house. All follicles greater or equal to 4.0 mm diameter were dissected from each ovary, follicle size was recorded and follicular fluid was aspirated from each follicle and analyzed for its oestradiol and testosterone contents. A bi-modal distribution of follicles was observed when frequency was plotted against oestradiol:testosterone ratio. On this basis, individual follicles were classified as oestrogenic or non-oestrogenic if they had follicular fluid oestradiol:testosterone ratio of greater or equal to 6:1 or 6:1, respectively. The total number of follicles did not differ between the two ovaries (right 56.9%; left 43.1%). Similarly, the number of oestrogenic and non-oestrogenic follicles was similar between the two ovaries. Moreover, no difference was observed between the percentage of oestrogenic and non-oestrogenic follicles within the right or the left ovaries. In addition, there was no difference in the diameter of oestrogenic and non-oestrogenic follicles. The results suggest that in the camel, both ovaries are equally capable of producing normal preovulatory follicles.
