Corticosteroids (glucocorticoid and mineralocorticoid) produced by the adrenal cortex are crucial for keeping homeostasis. The ovary is exposed to the circulating corticosteroids throughout life yet little is known about the physiological effects of the steroids on the ovarian function. We have demonstrated that ovaries of various species such as rats, human and cattle express receptors and metabolizing enzymes for these corticosteroids and they are dramatically regulated during folliculogenesis and ovulation. These results strongly imply corticosteroids play important roles in the ovarian physiology. We are currently investigating roles of corticosteroids in the bovine oogenesis and embryo development. Our aim is to improve quality and efficiency of in vitro production of embryos.
