Abstract

This study investigates the influence of ovarian side and pregnancy status on the ovarian morphometry and follicular population in Camelus dromedaries. Two groups were studied: the first group included non-pregnant camels, while the second group included pregnant camels. The current study assessed ovarian morphometry (dimensions, weight) and follicular count in the ovaries of both groups. Results showed that the total follicular populations and the average number of small-, medium-, and large-sized follicles were significantly higher (P > 0.05, P > 0.01, respectively) in the left non-pregnant Camelus dromedary ovaries than those of the right ones. In pregnant camels, both the dimensions and weight of ovaries containing corpus luteum (CL) were significantly greater (P< 0.01) than those of ovaries without a CL. The total follicular populations of pregnant ovaries bearing a CL were significantly higher (P< 0.05) than those of non-bearings CL. Moreover, the mean number of small and medium follicles in pregnant ovaries bearing a CL was significantly (P< 0.01) higher than those of pregnant ovaries non-bearing CL. On the other hand, the mean number of large follicles in pregnant ovaries non-bearing CL was significantly (P< 0.01) higher than those of pregnant ovaries bearing a CL. In conclusion, the study highlights that ovarian side influences the total follicular count and size distribution, while the presence of the CL significantly affects ovarian morphometry. These findings provide valuable insights into the reproductive physiology of dromedaries, which are essential for optimizing breeding management strategies in this species.
