<P> The corpus luteum ( Latin for `` yellow body '' ; plural corpora lutea ) is a temporary endocrine structure in female ovaries and is involved in the production of relatively high levels of progesterone , moderate levels of estradiol , inhibin A and small amounts of estrogen . It is the remains of the ovarian follicle that has released a mature ovum during a previous ovulation . It is colored as a result of concentrating carotenoids ( including lutein ) from the diet and secretes a moderate amount of estrogen to inhibit further release of gonadotropin - releasing hormone ( GnRH ) and thus secretion of luteinizing hormone ( LH ) and follicle - stimulating hormone ( FSH ) . A new corpus luteum develops with each menstrual cycle . </P>
