BRD2 and polycystic ovary syndrome: Aberrant dynamics of follicle development during early stages leading to disproportionately more granulosa cells per oocyte in transitional and primary follicles may be the cause of such accelerated development.[11] Some authors have also proved that the granulosa cells cultured from follicles derived from anovulatory women with PCOS are hyperresponsive to FSH in terms of estradiol production.[12, 13] It is clearly indicated in our study that zooming of follicles is significant high (P < 0.001) among Group III patients who had bigger antral follicles.
