Verified

After ovulation estrogen and progesterone secretions from corpus luteum slow down the hypophyseal LH and FSH secretions (It happens by inhibition of GnRH, gonadotropin-releasing hormone, hypothalamic hormone).  The blood concentration of these adenohypophyseal hormones drops to basal points again. When LH lowers corpus luteum (luteum stand for “yellow”) becomes atrophic and turns into corpus albicans (“white”). With regression of the corpus luteum the generation of progesterone and estrogen ceases.
