How does the hypophysis-corpus luteum negative feedback work? What is the name given to the atrophied corpus luteum after this feedback process?

After ovulation the estrogen and progesterone secretions from the corpus luteum inhibit the hypophyseal FSH and LH secretions (this happens by inhibition of GnRH, gonadotropin-releasing hormone, a hypothalamic hormone). The blood concentration of these adenohypophyseal hormones falls to basal levels again. As LH lowers the corpus luteum (luteum means "yellow") becomes atrophic and turns into the corpus albicans ("white"). With the regression of the corpus luteum the production of estrogen and progesterone ceases.
