If fertilization does not occur, which hormone promotes luteolysis and cessation of progesterone production?

Explanation:
Luteolysis in the absence of fertilization is driven by prostaglandin F2 alpha released from the uterus. This hormone acts on the corpus luteum to cause its regression, leading to a fall in progesterone production. Without progesterone, the reproductive system resets and the cycle can begin again. Estrogen isn’t responsible for terminating the luteal phase; it mainly regulates follicular development and uterine preparation. Progesterone is the hormone produced by the corpus luteum and maintains the luteal phase, not promotes its breakdown. LH supports the corpus luteum during the luteal phase in many species, so it isn’t the signal for luteolysis.
