abstract：:The effects of short-term genistein exposure on ovarian folliculogenesis in immature rats were examined stereologically. To determine whether genistein acts as an estrogen agonist or antagonist, the results were compared with the effects of 17α-ethynylestradiol. Immature female rats received 50 mg/kg/bw of genistein i...
