Description of folliculogenesis with a brief explanation of what happens after ovulation. See this video post: https://medvetsite.com/folliculogenesis/ _________________________________________________________________________________________________ Summary of folliculogenesis: Folliculogenesis is the development of ovarian follicles from a reserve (in which they are found as inactive primordial follicles) established in the first years of life in female mammals. The follicle is a structure composed of somatic cells (follicular or granulosa cells, theca cells, and ovarian stromal cells) that surround the female germ cell (the oocyte). These cells are modified each time a cohort (group of primordial follicles) develops. This is called "leaving the reserve." When follicles leave the reserve, they transform from primordial follicles to primary follicles in transition, and the surrounding pregranulosa squamous cells transform into cuboidal granulosa cells and begin to proliferate. The name given to each stage of follicular development varies depending on the bibliographic source, but the process is the same. The gradual process of development and differentiation of a follicle, from a primordial structure to a preovulatory follicle, takes approximately 6 months in larger mammals, such as humans and cattle. The importance of folliculogenesis lies in that it allows for the development of female gametogenesis (oogenesis) and ovarian steroidogenesis. Both processes occur simultaneously for ovulation to occur. _________________________________________________________________________________________________ References Bradley, G. K. (2014).
