Morphometrical Study on Pre-Antral Ovarian Follicles of Buffalo During Different Seasons

Abstract

The present study was conducted on left and right ovaries of 100 adult buffaloes during different seasons. The whole ovary was cut serially at a thickness of 10 µ. Every 20^th section was stained with haematoxylin and eosin stain and the number of pre-antral (primordial and primary) follicles in an ovary was counted. The
primordial follicles had flattened pre-granulosa cells that became cuboidal and divided during follicular activation which was an index of activation. The average number of primordial and primary follicles was significantly (p < 0.05) higher during winter and autumn as compared to other seasons. The number of follicles was more in right ovary as compared to left, though the difference was insignificant.
