| Abstract | ||
| The present study aimed to study the development and degeneration of ovarian follicles in goat during autumn and summer seasons. Seven ovaries were collected during each season from different popular markets. The ovaries were fixed in 10% neutral buffered formalin for histological examination. In autumn season; the histological examination revealed an increased ovarian activity that represented by presence of all developmental stages of ovarian follicles ( Primordial follicles, primary follicles, secondary follicles, tertiary follicles and mature Graafian follicles), corpus luteum, corpus albicans and corpus heamorrhagicum. In summer season; the histological examination revealed decreased ovarian activity. The mature Graafian follicles contained degenerated oocytes and abnormal arrangement of cumulus oophorus and granulosa cells. Also, presence of persistant corpus luteum where lutein cells became small with pyknotic nuclei, and presence of large number of atretic follicles (degenerated follicles). | ||
