Explain the changes in progesterone production that occur when fertilization does occur and when fertilization does not occur
What will be an ideal response?
If fertilization occurs, progesterone from the corpus luteum inhibits the release of gonadotropins and will continue to do this. If fertilization does not occur, the corpus luteum degenerates into the corpus albicans and estrogen, progesterone, and inhibin levels drop. With ovarian hormones no longer inhibiting secretion of GnRH, its levels rise and the cycle begins again.
