Oocyte from a developing follicle
WebFrom the time a follicle has been selected, the follicle destined to ovulate greatly enlarges and shows marked changes in its steroidogenic activity. LH surge causes a significant decline in gap junctions leading to dissociation of mural granulosa cells (GC) and expansion of the cumulus-oocyte complex (COC). WebOogenesis is an important and complex process in mammals facilitating female gamete development and is regulated by numerous intra- and extra-ovarian factors. The …
