Histological and histochemical features of ovary in adult female one humped camel Camelus dromedarius in AL-Muthanna province

This study aimed to focus light on the gross and histomorphometry structure in addition to histochemical features of the camels' ovary. For this study, 7 ovaries (left and right) from adult female camels were used. The camel's ovary was huge, irregularly shaped, and appeared spherical to oval and not smooth surfaces that was somewhat convex on the medial and lateral surfaces. The ovaries have a variety of elevated follicles, big follicle, the corpus luteum, corpus albicanus. The medial and lateral surfaces are transparent and include several protrusions that may indicate the presence of growing follicles or yellow bodies. The ovaries' oval to irregular form was caused by these bodies. One or two performed, white, regressing corpus luteums and one or two tiny, developing follicles are seen in one or two ovaries. Simple cuboidal epithelium covered the ovaries' surface, and it was continually present at the hilus with the ovarian ligament's mesothelium. The ovary was covered by a germinal epithelium beneath a cortex that was packed with vascular medulla and several follicle maturation phases. The mature follicles had cumulus oophorous, granulosa cells around the usual oocytes, and a wide antrum and thick theca. revealed the cortex, which included many primordial follicles, was filled with various phases of growing follicles, encircled by stromal cells that were grouped in a concentric pattern, giving the appearance of a spindle, and having spindle basophilic nuclei in the center. Zonapellucida had a robust positive PAS response. The majority of reproductive structures are found in the ovarian cortex. The she-camel's ovaries had varying numbers of the follicles at different stages of development. The left ovary was larger than the right in every way, and it had more noticeable yellow bodies and ovarian follicles. Conclusion, demonstrated the follicular growth in camels took place in a follicular wave, that ovulation may take place in both ovaries, and that the left ovary's follicular activity may be marginally greater than the right ovary's
