Histomorphological Changes in the Reproductive Tract of Female Hemiechinus auritus collaris,Gray in Relation to the Estrous Cycle
Authors:Asha Sharma  R S Mathur
Abstract:The average length of the estrous period is 7.9 days in Hemiechinus auritus collaris. Follicular development takes place cyclically. Maximum atresia of follicles is noticed during metestrus. The corpus luteum is formed by the shrinkage of the remaining granulosa cells of the ovulated follicle. Maximum development of the corpus luteum is seen during the pregnancy. Histological changes in the uterus and vagina during the estrous cycle are described. There is a marked rise in the weight of the uterus and ovary during the proestrus phase of the cycle. The estrus phase is characterized by the signs of degeneration in the uterine epithelium. During metestrus degeneration and regeneration proceed together. Secretory activity is at a minimum and the lumina of the glands are empty during diestrus.
