Later granulosa cells disappear and the fibroblasts invade the cavity (Fig. 7). The basement membrane between theca and granulosa becomes thick and hyalinized, but the theca interna persists for a while. This pattern is more pronounced in premenarche, pregnancy, and in polycystic ovary syndrome. [19] The theca interna cells produce androstenedione, which, in the absence of granulosa, is not transformed into estradiol, and their microenvironment is predominantly androgenic. E. Atretic Follicles Of the original 1–2 million primordial follicles present at birth only 400 ovulate.

56–58] 20 The Normal Human Ovary Part I As a result, preantral follicles do respond to gonadotropins with cell division and differentiation. However, it is clear that follicles can progress even to the antral stage in the absence of gonadotropins. A clinical demonstration of this fact is seen in ovulation induction efficiency in women with hypogonadotropic hypogonadism. [23] In summary, these early phases of initial follicle recruitment up to the small antral stage reflects two processes: (1) The emergence from the restraints of stasis, arrest, and growth inhibitory or repressive factors, and (2) the gradual but accelerating emergence of intrafollicular growth promotion and endocrine assisted survival factors preparing for increased FSH responsiveness of the growing follicles.

And intrinsic (autocrine, paracrine) mechanisms. For example, by secreting increasingly high levels of estradiol and inhibin B, the selected follicle suppresses FSH availability. [19–22] In summary, whereas preantral growth displays increasing degrees of FSH responsiveness, the events governing the fate of the selected follicle reflect complete dependence on FSH and the intrafollicular (intrinsic) mechanisms that maximize and ensure follicle survival and further development. The complex events that yield an oocyte for fertilization and the ovarian processes that protect and support follicle function involve practically every regulatory mechanism in human biology.
